SUBJECT: INTRODUCE AN ORDINANCE AMENDING TITLE 5 (PERMITS,
LICENSES, AND REGULATIONS), TITLE 16 (SUBDIVISION
REGULATIONS), AND TITLE 17 (ZONING REGULATIONS) OF THE
MUNCIPAL CODE.
RECOMMENDATION
As recommended by the Planning Commission, introduce a Draft Ordinance entitl ed, “An
Ordinance of the City Council of the City of San Luis Obispo, California, Amending Title
16 (Subdivision Regulations), Title 17 (Zoning Regulations), and Title 5 (Licenses,
Permits, and Regulations) of the Municipal Code regarding Accessory Dwellin g Units,
Junior Accessory Dwelling Units, Urban Lot Splits, Mobile Homes, and other Clarifications
and Changes to Regulations Associated with Housing, with an Exemption from
Environmental Review (CEQA).”
REPORT-IN-BRIEF
In 2025, several bills implementing changes to state law regarding accessory dwelling
units (ADUs), junior accessory dwelling units (JADUs), and urban lot splits went into
effect, with the continued intention of streamlining and incentivizing housing production
statewide. Some of these changes, in turn, require modifications to the City’s Municipal
Code to maintain compliance with state law.
The City of San Luis Obispo is designated as a Prohousing city by the California
Department of Housing and Community Development (HCD). This designation is
assigned to cities that implement local policies beyond what is provided by the state that
seek to remove barriers to new housing development. This designation allows the City to
receive priority processing and additional points when applying for state funding
programs. Therefore, staff continue to reevaluate the City’s Municipal Code and its review
processes for improvements to continue facilitating housing development beyond the
changes required by new legislation. This process is further aided by public feedback
received throughout the past year, which contributed to some of the proposed
amendments.

Item 7a
Lastly, City staff have continued to evaluate the efficacy of existing standards and
procedures instituted through the Municipal Cod e. Based on staff and community
feedback, this update contains several miscellaneous amendments to the Municipal Code
to clarify City standards and procedures. The changes to the code include the following:
Clean-up of ADU code items relating to heights, setbacks, procedural
requirements, lot coverage, and definitions for state law compliance.
Update to Mobile Home Park Rent Stabilization Ordinance to remove long-term
lease exemption for state law compliance.
Clarifying fractional density requirements for density bonus project calculations.
Update of minor urban lot split regulations to comply with state law regarding
properties in historic districts and/or containing historic structures.
Minor revisions to language in the Homestay regulations, clarifying t hat failure to
submit required information annually constitutes grounds for revocation of permit.
Revisions to Accessory Structure regulations to clarify definitions and achieve
compliance with ADU requirements.
Addition of language to the Driveway Standards for driveway approach sight
triangles for consistency with the Engineering Standards.
POLICY CONTEXT
The California State Legislature has passed several bills requiring updates to the City’s
Municipal Code to maintain consistency with state housing law. The proposed
amendments are necessary to comply with state law, as well as provide for more efficient
processing or clarification, and are supported by City policy as described below.
On November 17, 2020, the City Council adopted the 6th Cycle Housing Element (HE),
which includes housing policies and programs for 2020 -2028. Accessory Dwelling Units
(ADU) are an important part of the City’s housing production, addressing state mandated
Regional Housing Needs Allocation (RHNA) and helping the City meet housing policy
goals. The current Housing Element contains the following policies that encourage
housing production.
HE Policy 2.4: Encourage housing production for all financial strata of the City’s
population, as allocated in the Regional Housing Needs Allocation, for the 6th cycle
planning period. The number of units per income category are: extremely low and very
low income, 825 units; low income, 520 units; moderate income, 604 units; and above
moderate income, 1,405 units.
HE Policy 8.1: Encourage housing development that meets a variety of special needs,
including large families, single parents, disabled persons, the elderly, students, veterans,
farmworkers, the homeless, or those seeking congregate care, group housing, single -
room occupancy, or cohousing accommodations, utilizing universal design.
HE Policy 6.8: To help meet the 6th cycle RHNA production targets, the City will support
residential infill development and promote higher residential density where appropriate.
Page 178 of 412
Item 7a
Community Development Department (CDD) staff also periodically review the City’s
Zoning Regulations to identify possible barriers to housing development. Several of the
proposed amendments aim to resolve identified barriers to development, as well as
provide for additional clarifications on regulations. This is especially important as housing
production is an integral part of the Housing and Neighborhood Liva bility Major City Goals
to “promote the expansion and diversification of housing opportunities for all” and
“Facilitate sustainable growth that aligns with climate, economic, and housing goals.”
DISCUSSION
New State Legislation
Provided below is a brief review of the various laws that went into effect in 2025 or at the
beginning of 2026 that this update integrates into the City’s Municipal Code. The
provisions introduced or altered by this legislation require amendments to Chapters 16.15
and 5.44 of the Municipal Code. These specific amendments are discussed later in the
report and can be viewed in Attachment A, respectively.
Senate Bill 1211
Senate Bill No. 1211 introduced several changes to Government Code sections 66313,
66314, and 66323, which deal with state ADU law. This bill prohibits local agencies from
requiring the replacement of off-street parking spaces if an uncovered parking space is
demolished in conjunction with the construction of, or conversion to, an ADU. It al so
prohibits local agencies from imposing any objective development or design standard not
authorized by the provisions listed in state ADU law and provides a definition for the
phrase “livable space” as being “a space in a dwelling intended for human habi tation,
including living, sleeping, eating, cooking, or sanitation.” Lastly, this bill allows up to eight
detached ADUs to be developed on a lot with an existing multifamily dwelling, provided
that the number of ADUs does not exceed the number of existing units on the lot.
Assembly Bill 1061
Assembly Bill 1061 introduced several changes to California Government Code Section
66852.21 that contain provisions pertaining to minor urban lot splits (a.k.a., SB -9 Lot
Splits). These changes allow for housing development pursuant to Section 66852.21 and
minor urban lot splits on properties within a historic district, which was previously
prohibited. State law still prohibits this type of development and subdivision on properties
that are listed as historic by the state and/or the City.
Assembly Bill 2782
Prior to January 1, 2025, state law (Civil Code Section 798.17) required that long-term
leases (those longer than twelve months) be excluded from local mobile home park rent
stabilization ordinances. Assembly Bill 2782, which was enacted in 2020, eliminated this
requirement effective January 1, 2025, meaning that these local ordinances may now
Page 179 of 412
Item 7a
include long-term leases in their rent stabilization protections. This allows most long-term
residents of mobile home parks to be protected from unauthorized rent increases in
violation of the City’s rent stabilization ordinance.

Item 7a
Miscellaneous ADU-Related Changes
Staff has proposed several miscellaneous amendments related to ADUs. These changes
were identified as possible barriers to housing development, possible inconsistencies with
state law, or items that would benefit from further clarification. These proposed
amendments are as follows:
Setbacks & Height: Both state law and the Zoning Regulations currently require
that new ADUs that include the creation of new square footage (i.e., new floor
space) with a side and rear setback of 4 feet are limited to a maximum height of
16 feet. The Zoning Regulations provide an additional pathway that allows higher
heights by allowing ADUs to be built to a maximum height of 25 feet (in excess of
state limits) so long as they comply with the setback standards required in the
underlying zone, beginning at a minimum of 5 feet for all residential zones.
However, state law also permits a height maximum of 18 feet with a side and rear
setback of 4 feet for a detached ADU on a property with a multistory multifamily
dwelling, as well as a height maximum of 25 feet with a side and rear setback of 5
feet for attached ADUs. Therefore, the current Zoning Regulations described
above are inconsistent with these additional height and setback allowances
provided by state law.
Section 17.86.020 is proposed to be amended to more clearly call out the height
and setback allowances permitted unde r state law. (Attachment A –
17.86.020(B)(3)(c).)
Additional Height Allowance: As stated above, the Zoning Regulations currently
allow ADUs a maximum height limit of 25 feet in any zone, if the ADU is compliant
with the underlying zone’s setback requireme nts. The City has received feedback
from the public to consider deferring ADU height limits to the underlying zone, as
is done for all other standards not accounted for in Section 17.86.020. Staff
considered this input and have updated this provision of Section 17.86.020 to defer
to the underlying zone standards for ADU height limits.
Deferring to the underlying zone standards is more permissive than state law and
could potentially increase ADU development in certain zoning districts, such as the
R-2 and R-3 zones, by allowing ADU designs to be more consistent with the typical
development pattern in said zones, which allow heights of up to 35 feet. This
change would not impact ADUs in the R-1 zone, as the current ADU maximum
height limit of 25 feet matches the height limit for structures in the R-1 zone. ADUs
that are built with a height in excess of state law allowances described above will
be required to comply with the setback standards of the underlying zone.
(Attachment A – 17.86.020(B)(3)(d).)
Procedural Requirements: In a previous update to the Zoning Regulations
pertaining to ADUs (adopted on April 1, 2025), staff introduced a provision under
Page 181 of 412
Item 7a
the “Procedural Requirements” subsection of Section 17.86.020 that attempted to
address issues related to attached ADUs and a “two-step” process that was
occurring with the development of ADUs pursuant to California Government Code
Section 66323.
The “two-step” process was utilized by developers to build an accessory structure
(step 1) and then take advantage of the state law requirement allowing
construction of an ADU by converting the accessory structure (step 2). This was
necessary for the development of attached ADUs, particularly on properties that
had an existing ADU, prior to 2025 when ADU development was restricted to 1 per
lot.
Upon feedback from developers and the community of the difficulty in utilizing the
“two-step” process, staff updated the “Procedural Requirements” to allow for a one-
step process for attached ADUs, eliminating the need to complete the construction
of the accessory structure before conversion to an ADU.
Since its implementation, this portion of the Procedural Requirements subsection
of the Zoning Regulations has not been widely utilized and it may potentially
conflict with state law which expressly allows for the construction of attached ADUs
in addition to detached ADUs on a parcel with a single-family residence. Staff’s
change to remove the 1 ADU per lot restriction in 2025 addressed this problem.
Therefore, this update proposes an amendment to Section 17.86.020 to remove
this provision entirely. (Attachment A – 17.86.020(B)(4)(c).)
Exceptions from Discretionary Review: The Zoning Regulations provide
instances in which additional discretionary review is required for ADU
development. These include properties that are subject to the Hillside
Development Standards (Section 17.70.090(E)) and additions to nonconforming
structures (Section 17.92.020(F)). However, state law prohibits the use of a
discretionary process to review ADUs that are compliant with all applicable ADU
state standards.
This update includes changes to Sections 17.70.090 and 17.92.020 that would
provide clear exceptions to the discretionary review process requirement under the
Hillside Development Standards and additions to nonconforming structures for
ADUs that are compliant with applicable ADU standards. (Attachment A –
17.70.090(E) & 17.92.020(G))
Expanding the ADU Definition: The Zoning Regulations provide a general
definition for ADUs. The City has received feedback from the public that additional
clarification is needed for an attached versus detached ADU. This update adds
additional language to the ADU definition provided under Section 17.156.004 that
further describes what constitutes an attached versus a detached ADU.
(Attachment A – 17.156.004)
Lot Coverage: The Zoning Regulations provide ADUs an exception to lot
coverage requirements as required by state law. The first 800 square feet of lot
coverage on a property for an ADU is exempt and anything in excess of that first
800 square feet is included in a property’s lot coverage calculation. This update
Page 182 of 412
Item 7a
would modify the current language under Section 17.70.120 to more clearly
articulate this lot coverage exception for ADUs. (Attachment A – 17.70.120(B))
Mobile Home Update
With Civil Code Section 798.17 repealed by AB 2782, the City is no longer required to
exclude long-term space leases from its mobile home park rent stabilization ordinance
(MHPRSO) found in Chapter 5.44 of the Municipal Code. Since the MHPRSO expressly
includes the long-term lease exemption in Section 5.44.030, rather than simply referring
to state law exemptions,1 removal of this exemption requires an amendment to the
ordinance (by deleting SLOMC § 5.44.030(E)). The long-term lease exemption has been
a significant loophole utilized by mobile home park owners across the state, and Council
directed staff at the 2025 Study Session on Renter Protections to bring this amendment
forward so that long-term mobile home residents are protected by the rent stabilization
ordinance.
Staff also recommends deletion of Section 5.44.040 as a clean-up of the MHPRSO to
reflect a 1992 amendment modifying the Ordinance’s exemptions. In 1988, the City
adopted a voter-approved version of the MHPRSO, in which Section 5.44.030(F) was an
exemption for “spaces in a mobile home park in which at least 66.67% of said spaces are
governed by a lease with an initial term of more than one year.” (see Ord. 1117 (1988
Series).) In 1989, the City adopted Ordinance 1146, establishing Section 5.44.040, the
procedures for “claiming an exemption under Section 5.44.030(F),” which, at the time,
was the 2/3 long-term lease exemption established by Ordinance 1117. Section 5.44.040
has not been modified since 1989. In 1992, the City adopted Ordinance 1228, which
deleted Subsections F and G and created a new subsection F (which is the same as its
current iteration, related to factory-built housing.), however, Section 5.44.040 was not
concurrently deleted and still sets forth procedures for a Subsection F exemption that no
longer exists. Deletion of Section 5.44.040 and the reference to the 66.67% exemption in
Section 5.44.060(A) will clarify the intent of the 1992 amendment. (Attachment D –
5.44.030 & 5.44.040)
Fractional Density
Currently, the City’s Affordable Housing Incentives in Section 17.140.040 do not specify
whether to use fractional density units (fractional density units are established in the City’s
municipal code and measure density based on the number of bedrooms in each unit) or
dwelling units per acre (general number of units provided, regardless of the number of
1 Some jurisdictions have taken the position that AB 2782 automatically repealed the long -term lease
exemption within their rent stabilization ordinances. For jurisdictions like the City of Petaluma, this makes
sense because their ordinance simply included the exemptions in Civil Code Section 798.17 by reference
instead of codifying a separate exemption for long-term leases. Rather than referring to state law, San
Luis Obispo’s municipal code sets forth a standalone long-term lease exemption that requires removal by
amendment to the MHPRSO.
Page 183 of 412
Item 7a
bedrooms in each unit) when calculating the amount of density bonus units awarded
and/or the amount of affordable units to be provided by the developer.
Under Section 17.70.040, the City calculates the maximum allowed density for a property
based on fractional density units, not dwelling units per acre. Density for a studio/one -
bedroom dwelling is 0.50 density units if less than 600 square feet in size or 0.66 density
units if over 600 square feet but no more than 1,000 square feet in size, a two -bedroom
dwelling is 1.00 unit, a three-bedroom dwelling is 1.50 units, and a four or more-bedroom
dwelling is 2.00 units. For example, the following density bonus project uses fractional
density units:
The developer for a residential project that would provide five density units worth
of dwellings applies for a 50 percent density bonus. This bonus would allow for a
total of 8 density units (after rounding), where two density units of affordable units
must be provided (after rounding). Under fractional density, the market -rate units
could be provided as eight two-bedroom units, with two of them provided as
affordable units.
However, there are two issues that occur under the current provisions provided in Section
17.140.040. Because this section does not clarify when and how fractional density can
be used, an applicant may maximize the number of market rate units built under fractional
density (e.g., six two-bedroom units) while minimizing the number of affordable units (e.g.,
two studio units, where under fractional density, two two-bedroom units would be
required).
Another issue is the way fractional density units can be applied to decrease the total
number of affordable units provided. Referring to the density bonus project example
above, the applicant is required to provide two density units of affordable housing to
qualify for a 50 percent density bonus. They provide six market -rate two-bedroom units,
but instead of two affordable two-bedroom units, they provide one four-bedroom dwelling
unit. Although under Section 17.70.140 a four-bedroom unit is worth two density units,
Density Bonus Law, Government Code Section 65915(r), states that the intent of this law
is to be interpreted as favoring the production of the maximum number of total housing
units, including the affordable units. Therefore, to comply with Density Bonus Law, the
applicant should be required to provide two, two-bedroom dwellings.
This update would add language to Section 17.140.040 requiring fractional density units
to be applied consistently for both the market rate and affordable units within a density
bonus project, and that fractional density shall only be utilized in favor of producing the
maximum number of affordable housing units provided. (Attachment A - 17.140.040)
Minor Urban Lot Splits and Housing Development In Historic Districts
Currently, the Subdivision Regulations prohibit minor urban lot splits, and in turn, housing
development pursuant to the same state laws that govern urban lot splits, in historic
districts and on properties listed as a historic resource by the state and/or City. This
restriction was consistent with state law at the time it was instituted.
Page 184 of 412
Item 7a
With the passage of Assembly Bill 1061, this restriction was modified, specifically allowing
minor urban lot splits and associated housing development on properties located within
a historic district. The restriction still remains for properties that are designated as historic
resources by the state and/or City. This update would adjust this provision in Section
16.15.020 to maintain compliance with state law. (Attachment A – 16.15.020(C))
Homestay Regulations
Section 17.86.160 provides requirements that operating Homestays must comply with to
apply for a Homestay permit. The requirements include the following:
Operators of homestays in all zones are required to obtain a homestay permit and
a business license.
The operator of the homestay shall pay transient occupancy tax and tourism
business improvement district tax as required by the municipal code.
The operator of the homestay shall annually provide verification of primary
residence through the homeowner’s property tax exemption or other appropriate
documentation.
The operator of the homestay shall provide the name and contact information of a
responsible party in the application if the owner-occupier anticipates he or she may
not be on the premises at all times during the homestay rental.
This update would add language to Section 17.86.160 clarifying that these requirements
must be complied with on a continuous basis and that Home stays that do not comply with
applicable requirements shall automatically expire, rather than the previous regulations
which necessitated a revocation hearing. This change will allow staff to proactively
monitor active homestays and ensure they are complying with requirements on a regular
basis, leading to more effective compliance for homestays in the City. (Attachment A –
17.86.160(E))
Accessory Structures
In review of Chapter 17.70 of the Municipal Code, staff identified outdated and restrictive
provisions in Section 17.70.010 pertaining to accessory structures. This update includes
changes to Section 17.70.010 to address these items and are as follows (Attachment A
– 17.70.010):
Modifying the term “secondary dwelling unit” used in this section to “accessory
dwelling unit.” The term “secondary dwelling unit” was used to refer to accessory
habitable space, which is now known as an ADU.
This section currently limits the number of accessory structures to three per lot,
only one of which may include a habitable accessory structure like an ADU. This
is inconsistent with both Section 17.86.020 of the City’s Municipal Code and state
Page 185 of 412
Item 7a
law. This language would be removed and replaced with a provision specifically
stating that the limit on accessory structures would not apply to ADUs and JADUs.
This section contains a provision requiring a property owner to record a covenant
agreement disclosing the accessory structure’s approved floor plan and status and
allowing for annual inspections by the City. The City has received feedback that
this requirement is particularly restrictive for what are otherwise minor projects.
The purpose of this requirement was to prevent the illegal conversion of accessory
structures into habitable spaces. However, since this provision was added to the
Zoning Regulations, ADUs and JADUs have become highly regulated and
pathways for “illegal” ADUs to become permitted units have been instituted by
state law. This update would remove this provision entirely.
Driveway Visibility Clarification
Section 17.70.210 provides provisions for intersection visibility requirements at roadway
intersections not controlled by a stop sign or traffic signal that prohibit plants, structures,
or other solid objects over three feet tall to be located within “sight triangles” further
described in this section. These provisions are based on Engineering Standard 7950,
which was updated in 2025, expanding this same requirement to driveway approaches.
This update would add a provision and figure specifically for driveway approach visibility
requirements to Section 17.70.210. This update will achieve consistency with current
Engineering Standard 7950. (Attachment A – 17.70.210)
Use Permit Clarification for General Retail
Section 17.26.030(A) provides maximum gross floor area limits for retail uses in the C -N
(Neighborhood Commercial) zone. It also provides that exceptions to these limits may be
granted through the approval of a Minor Use Permit. However, Table 2-1 of Chapter 17.10
(Use Regulations) indicates a Minor Use Permit is required for approval of a general retail
use in the C-N zone.
General retail is allowed by right in the C-N zone, and staff have determined that the
“MUP” note in Table 2-1 was mistakenly provided. Previous versions of this table included
individual line items describing what was allowed by right or what required discretiona ry
review based on the gross floor area limits. In 2018, Table 9 (now referred to as Table 2 -
1) was updated, which included the reduction of these items to one line referring to
“General Retail” as a whole, with a note to Section 17.26.030(A) to defer to the exceptions
allowed. However, this use was marked as requiring a Minor Use Permit in the C-N zone
where it should have been marked as allowed by right. This update would remove the
“MUP” designation from Table 2-1 for general retail uses in the C-N zone. (Attachment A
– 17.10.020)
Page 186 of 412
Item 7a
Setback Clarification for Decks
Section 17.70.170 contains provisions that permit decks with a height that exceeds 30
inches above grade to encroach into side and rear yard setbacks no more than four feet
or one-half the required setback, whichever is less. At the same time, it also provides that
certain structures, including decks with a height of 30 inches or less, may also be located
within required setbacks. However, the Municipal Code does not clearly state this, and
staff have received feedback from the public requesting this point be clarified. This update
would include changes to Section 17.70.170 that clearly specify that decks with a height
of 30 inches or less above grade are not subject to setback requirements. (Attachment A
– 17.70.010(C))
Feedback Received Regarding Additional Zoning Code Updates
During the year, staff has received questions and suggestions from the community and
individual Councilmembers regarding additional desired changes to the Zoning
Regulations, generally related to commercial uses. These Included allowing office use in
manufacturing zones, whether there are any necessary child care business related
changes to facilitate more childcare uses and allowing massage or physical therapy uses
in the office zones. Staff analyzed these changes to potentially include in this zoning
code update, however, they were not included at this time.
Family day cares are already an allowed use in all zones except the Conservation/Open
Space and Public Facilities zones, and it has not been staff ’s experience that there are
zoning barriers prohibiting the establishment of daycare uses in the City. Physical therapy
uses are allowed in the Office zone as they are typically operated by licensed medical
professionals, meeting the classification of a Medical/Dental Office under the existing
regulations. However, massage services fall under the Personal Services classification,
which are not allowed in the Office zone. Allowing this classification would best be
considered as part of a larger General Plan update that considers the potential
ramifications, as personal services cover a wide range of uses such as barber shops,
beauty salons, tailors, day spas, dry cleaners, tattoo shops, etc. Similarly, allowing certain
office uses in the manufacturing zone would also be best to consider as part of a larger
General Plan update to ensure that there is sufficient space for manufacturing uses in the
City as outlined in the General Plan, and that there are not unintended consequences of
making this change. These topics warrant more in-depth study and analysis than was
possible for this item.
Previous Council or Advisory Body Action
On April 8, 2026, the Planning Commission, on a 6-0 vote (Tolle absent) adopted a
Resolution (Attachment B) which recommended that City Council introduce and adopt an
Ordinance amending Title 16 (Subdivision Regulations), Title 17 (Zoning Regulations),
and Title 5 (Permits, Licenses, and Regulations) of the Municipal Code regarding
accessory dwelling units, junior accessory dwelling units, urban lot splits, mobile homes,
and other clarifications and changes to regulations associated with housing, with an
Page 187 of 412
Item 7a
exemption from environmental review (CEQA), as represented in the staff report and
attachments.
Public Engagement
Public notice was provided for the April 8th Planning Commission meeting and no public
comment was received on the item. Public notice of this hearing has been published in a
widely circulated local newspaper, and hearing agendas for this meeting were posted at
City Hall, consistent with adopted notification procedures. Email notices have been
provided for each public meeting to those on the interested parties list.
CONCURRENCE
Planning, Building, and Engineering Division staff from the Community Development
Department, as well as the City Attorney’s Office, have reviewed the proposed changes
to Titles 16, 17, and 5 and provided feedback that has been incorpo rated into the
proposed amendments.
ENVIRONMENTAL REVIEW
The proposed code amendments to Title 16, Title 17, and Title 5 of the Municipal Code
have been assessed in accordance with the authority and criteria contained in the
California Environmental Quality Act (CEQA), the State CEQA Guidelines, and the
environmental regulations of the City. Specifically, the proposed amendments have been
determined to be exempt from further environmental review pursuant to CEQA Guidelines
Section 15061(b)(3), the “Common Sense” exemption, because the activity is covered by
the general rule that CEQA applies only to projects which have the potential for causing
a significant effect on the environment, and it can be seen with certainty that there is no
possibility that the activity in question may have a significant effect on the environment.
Individual discretionary developments will still be required to conduct environmental
analyses as appropriate. The proposed code amendments pertaining to ADUs and
JADUs are also exempt under Public Resourced Code Section 21080.17 that applies to
local ordinances implementing state regulations related to accessory dwelling units.

Item 7a
The Municipal Code changes implemented by this ordinance would not have a direct
fiscal impact on the City.
ALTERNATIVES
1. Continue consideration of the proposed amendments. An action continuing
the project should include direction for staff on pertinent issues that should be
further studied or analyzed for future Council consideration.
2. Do not approve the proposed amendments. Not approving the amendments
would result in the City’s Municipal Code not being consistent with state law.
Denying the proposed amendments would also not address the potential barriers
to housing production that have been identified within the City’s Municipal Code.
3. Modify the proposed amendments. Any modifications to the proposed
amendments would need to be sent back to the Planning Commission for approval,
then re-introduced at City Council, followed by a second reading before
implementation. This would create significant delays in implementing the proposed
updates to Titles 5, 16, and 17, several of which are necessary to maintain
compliance with state law requirements.

SECTION 1. Findings. Based upon all evidence, and as recommended by the
Planning Commission, the City Council makes the following findings:
1. The proposed amendments to Titles 16, 17, and 5 will not cause significant
health, safety, or welfare concerns since the amendments are consistent with
the General Plan and directly implement City goals and polices.
2. The proposed amendments to Title 17 are consistent with the 6th Cycle
Housing Element in promoting Goal 5 (Housing Variety) and Goal 6 (Housing
Production).
3. The proposed amendments to Titles 16, 17, and 5 are consistent with state law.
SECTION 2. Environmental Determination. The proposed code amendments to
Title 16, Title 17, and Title 5 of the Municipal Code have been assessed in accordance
with the authority and criteria contained in the California Environmental Quality Act
(CEQA), the State CEQA Guidelines, and the environmental regulations of the City.
Specifically, the proposed amendments have been determined to be exempt from further
environmental review pursuant to CEQA Guidelines Section 15061(b)(3), the “Common
Sense” exemption, because the activity is covered by the general rule that CEQA applies
only to projects which have the potential for causing a significant effect on the
environment, and it can be seen with certainty that there is no possibility that the activity
in question may have a significant effect on the environment. Individual discretionary
developments will still be required to conduct environmental analyses as appropriate. The
proposed code amendments pertaining to ADUs and JADUs are also exempt under
Public Resourced Code Section 21080.17 that applies to local ordinances implementing
state regulations related to accessory dwelling units.
SECTION 3. Title 5 LICENSES, PERMITS, AND REGULATIONS: Section
5.44.030 Exemptions is hereby amended as follows:

more than a year, but only for the duration of such lease or contract. Upon the
expiration of or other termination of any such lease or contract, this chapter shall
immediately be applicable to the tenancy. No rent increases other than that
allowed under the provisions of the lease shall be allowed during the duration of
such a lease or contract.
F. E. Spaces in a mobile home park which sells lots for factory-built or
manufactured housing, or which provides condominium ownership of such lots,
but only when the dwelling unit and the underlying interest in the space it is
located upon are in the same ownership. (Ord. 1228 § 1, 1992; Ord. 1117, 1988)

element and shall be subject to a recorded affordability restriction of at least
forty-five years.
2. If the parcel is not identified in the city’s housing element for the current
planning period, the development will result in at least sixty-six percent of

SECTION 8. Title 17 ZONING REGULATIONS: Section 17.70.010 Accessory
structures is hereby amended as follows:
17.70.010 Accessory structures.
A. Purpose.
1. Regulations on accessory structures are established to provide a
distinction between nonhabitable accessory structures (e.g., garage,
storage shed, shop building) and accessory living spaces (e.g., accessory
dwelling unit secondary dwelling units, guest quarters, office, pool house,
etc.). These regulations establish standards which prevent the conversion
of accessory structures into unpermitted living space to ensure that such
structures are not used as separate dwelling units.
2. Unpermitted conversion of accessory structures is detrimental to the
public health, safety, and welfare of the community.
B. Applicability.
1. Application. This section shall apply to:
a. New Structures. All new structures, as defined in the building code,
located on the same site as the primary structure or use to which it is
accessory, including, but not limited to, garages, carports, porte-
cocheres, sheds, workshops, gazebos, greenhouses, cabanas,
trellises, play structures, aviaries, covered patios, etc.

accessory dwelling units as defined in Section 17.156.004 (A Definitions),
and guest quarters as defined in Section 17.158.018 (G Definitions).
Accessory structures that include habitable space, as defined by the
California Building Code, shall be regulated by Section 17.86.020
(Accessory Dwelling Units and Guest Quarters).
C. Development Standards.
1. General Development Standards. Accessory structures shall conform to
all applicable zoning regulations such as height, yards, parking, building
coverage, setbacks (unless otherwise allowed, see Section 17.70.170(C)),
etc.
2. Incidental Use. The use of an accessory structure is incidental, and
subordinate to the use of the principal structure, or to the principal land use
of the site.
3. Form. Accessory structures may consist of detached structures or
additions to primary structures.
4. No Bathing Facilities. No bathing facilities (e.g., shower, bathtub) may
be installed. Plans submitted for a building permit may not include spaces
within a bathroom designed for the later addition of bathing facilities.
5. Limit on Total Number in Residential Zones. In residential zones, no
more than three accessory structures shall be permitted per lot, only one of
which may include a habitable accessory structure such as an accessory
dwelling unit or guest quarters. This limit does not apply to accessory and
junior accessory dwelling units.
D. Process Requirements.
1. Building Permit. Development of an accessory structure shall require
approval of a building permit from the city’s building division.

O ______
2. Design Review. Plans submitted for a building permit shall be reviewed
for consistency with the city’s community design guidelines and general
development requirements of the zoning regulations.
3. Owners Agreement with the City. Prior to the issuance of construction
permits, a covenant agreement shall be recorded that discloses the
structure’s approved floor plan and status as an “accessory structure” which
cannot contain living space, including bathing facilities or a kitchen. This
agreement shall be recorded in the office of the county recorder to provide
constructive notice to all future owners of the property. The covenant
agreement also may contain authorization for annual inspections, and to
allow the city upon reasonable time and notice to inspect the premises for
compliance with the agreement and to verify continued compliance with
requirements of this section and Health and Safety Codes. (Ord. 1650 § 3
(Exh. B), 2018)
SECTION 9. Title 17 ZONING REGULATIONS: Section 17.70.070 Fences,
walls, and hedges is hereby amended as follows:
17.70.070 Fences, walls, and hedges.
A. Purpose. The purpose of these regulations is to achieve a balance between
concerns for privacy and public concerns for enhancement of the community
appearance, visual image of the streetscape, overall character of neighborhoods,
and to ensure the provision of adequate light, air, and public safety.
B. Application. These regulations apply to any type of visible or tangible
obstruction that has the effect of forming a physical or visual barrier between
properties or between property lines and the public right-of-way, including but not
limited to: any type of artificially constructed barriers of wood, metal, or concrete
posts connected by boards, rails, panels, wire or mesh, and any type of natural

b. Street Side and Front Setback. Up to one arbor, trellis, or other
similar ornamental feature per street frontage is allowed with a
maximum height of nine feet, and an area of not more than forty square
feet as measured by the perimeter formed by the vertical projection to
the ground of the outermost elements of the feature, and no horizontal
dimension shall exceed eight feet in length. Any portion of such a
feature wider than eighteen inches and that exceeds the usual fence
height requirements of this section shall be of an open design such that
a person standing on the adjacent public right-of-way can see
completely through at least fifty percent of the structure to the depth of
the required street yard (see Figure 3-6: Arbors in Front and Street Side
Setbacks). Such features within required setbacks shall not be
connected to another structure or building. For the purposes of this
section, the term “connected” shall include structures that are rigidly
joined by structural components. Such features within required
setbacks shall not be constructed of heavy materials such as masonry
or metal. Such features within required setbacks comply with Section
17.70.210 (Vision Clearance Triangle at Intersections).

6. Pilasters. Decorative pilasters, statuary, flower pots, and similar
ornamental elements attached to or incorporated into the design of
conforming fences or walls may exceed the required height limit up to 18
inches, provided that the decorative element is not wider than eighteen
inches and that such elements are used to define a gateway or other
entryway or are otherwise at least four feet apart.
D. Standards for Fences Located Outside of Required Setback Areas. Fences,
walls, and arbors may be placed outside required setbacks, provided:
1. The maximum fence, wall, arbor or hedge height is eight feet.
2. Where the fence, wall, or arbor is connected to and a part of a building,
it may be any height allowed in the underlying zone.
E. Fence Height with Difference in Grade. Fence height is measured from the
adjacent grade along the lower side of the wall, fence, or hedge, directly at the
base of the wall or fence.
F. Measurement of Height Where Fences or Walls Are Located on Retaining
Walls.
1. Where fences or walls are located on retaining walls, the height of the
retaining wall shall be considered as part of the overall height of the fence
or wall. Walls or fences must have a minimum spacing of five feet between
each other to be considered separate structures for purposes of measuring
overall height.

2. Where fences are located on a berm or mound, the height of the fence
shall include the berm or mound directly beneath the fence and above
natural grade in the overall height measurement.
3. Where fences are located on retaining walls within interior side or rear
setbacks, fences shall not exceed six feet as measured from the uphill side
if erected or replaced on top of the retaining walls, and the combined fence
and retaining wall height shall not exceed nine feet from the lower side,
provided no modification of grade has occurred from the original subdivision
improvements and/or design approvals. A building permit is required for the
combined fence and retaining wall height that exceeds six feet. If there is
evidence that a modification to the grade has occurred from the original
subdivision/design approvals, the height must be authorized through a
fence height exception pursuant to Chapter 17.108 (Director’s Action). For
retaining walls in hillside areas, see also Section 17.70.090(C)(3) (Retaining
Walls).
G. Intersection and Driveway Visibility. Notwithstanding other provisions of this
section, fences, walls, and hedges shall comply with Section 17.70.210 (Vision
Clearance Triangle at Intersections and Driveways).
H. Director’s Action. The director, through a director’s action, may grant
exceptions to standards of this section as set forth in Chapter 17.108 (Director’s
Action) when there is no practical way to comply with the provisions and no other
feasible alternatives will result in better implementation of other zoning
regulations or general plan policies while allowing reasonable use of sites.
Circumstances where a director’s action may be approved include, but are not
limited to, issues related to topography and privacy. (Ord. 1705 §§ 17, 22, 2021;
Ord. 1650 § 3 (Exh. B), 2018)
SECTION 10. Title 17 ZONING REGULATIONS: Section 17.70.090 Hillside
development standards is hereby amended as follows:
17.70.090 Hillside development standards.
A. Purpose and Application.
Page 205 of 412
Ordinance No. _____ (2026 Series) Page 16
O ______
1. Purpose. The purpose of this section is to implement goals of the
Conservation and Open Space and Land Use Elements of the General
Plan:
a. To protect and preserve scenic hillside areas and natural features
such as the volcanic morros, ridge lines, plant communities, rock
outcroppings and steep slope areas that function as landscape
backdrops for the community;
b. To avoid encroachment into sensitive habitats or unique resources
as defined in the Conservation and Open Space Element;
c. To protect the health, safety and welfare of community residents by
directing development away from areas with hazards such as
landslides, wildland fires, flooding and erosion; and
d. To protect the city’s scenic setting.
2. Application. The provisions of this section shall apply to all lots and sites
that have an average cross slope of sixteen percent or more (see Section
17.70.090(B): Average Slope Calculation). The director may require a
survey and slope analysis to determine whether the provisions of this
section apply to a specific property or development. Notwithstanding the
requirements of this section, a lot created pursuant to the Subdivision Map
Act and Title 16 (Subdivisions) of the San Luis Obispo Municipal Code prior
to the effective date of this division may be developed with a single unit
structure in compliance with other applicable requirements of these zoning
regulations.
B. Average Cross-Slope Calculation. Average cross-slope is the ratio,
expressed as a percentage of the difference in elevation to the horizontal
distance between two points on the perimeter of the area for which slope is being
determined. The line along which the slope is measured shall run essentially
perpendicular to the contours.
1. Where a site does not slope uniformly, average cross-slope is to be
determined by proportional weighting of the cross-slopes of uniformly
sloping subareas, as determined by the director.
Page 206 of 412
Ordinance No. _____ (2026 Series) Page 17
O ______
2. Cross-slope determinations shall be based on the existing topography
of the net site area after subtracting the area for any future on-site grading
necessary to accommodate proposed right-of-way improvements and other
on-site improvements.
3. Cross-slope shall be calculated only for the net area as defined in
Section 17.70.110 (Lot Area).
C. Hillside Development Standards.
1. General Site Planning Standards. To assist in maintaining a natural
appearance for hillsides and ridgelines, each structure shall be located in
the most accessible, least visually prominent, most geologically stable
portion or portions of the site, at the lowest feasible elevation, and shall, at
a minimum, meet the following requirements:
a. See Section 17.70.040(A)(2) (Maximum Development Density—
Sloped Sites) for maximum density in hillside areas.
b. See Section 17.70.090(B) (Building Height on Slopes with Sixteen
Percent Grade or Greater) for maximum height in hillside areas.
2. Site Access and Driveways. Each driveway shall not have a grade
steeper than five percent within ten feet of a garage or carport entry.
Driveway finished grade shall not exceed an average of fifteen percent, or
twenty percent at any point.
3. Retaining Walls. Retaining walls that are twenty feet in length shall be
limited to six feet in height (above ground/visible portion). Retaining walls
longer than twenty feet shall be limited to four feet in height (above
ground/visible portion). A minimum five-foot horizontal separation is
required between retaining walls. For exceptions, see subsection D of this
section.
4. Downhill Building Walls. No single building wall on the downhill side of a
house shall exceed fifteen feet in height above grade. Additional building
height on a downhill side is allowed in fifteen-foot increments, where each
increment is stepped-back from the lower wall a minimum of ten feet.

Ordinance No. _____ (2026 Series) Page 18
O ______
5. Height of Lowest Floor Level, Decks, and Support Structures. See
Figure 3-9: Height Limit for Lowest Floor, Decks, and Support Structures.
a. Lowest Floor Level. The vertical distance between the lowest point
where the foundation meets grade and the lowest floor line of the
structure shall not exceed six feet.
b. Decks. No portion of the walking surface of a deck with visible
underpinnings shall exceed a height of six feet above grade.
c. Support Structures. Support structures (e.g., columns, pilings, etc.)
below the lowest floor on the downhill side of a house shall be enclosed
unless visible structural members are an integral feature of the
architectural design. Support structure wall surfaces shall not exceed
six feet in height.
Figure 3-9. Height Limit for Lowest Floor, Decks, and Support
Structures
6. Exterior Wall Surfaces.
a. Single-story and small-scale elements, setbacks, overhangs, roof
pitches, and/or other means of horizontal and vertical articulation shall be
used to create shade and shadow and break up otherwise massive forms to
minimize the apparent size of exterior wall surfaces visible from public
rights-of-way.
Page 208 of 412
Ordinance No. _____ (2026 Series) Page 19
O ______
b. Large flat building planes are prohibited; the spatial arrangement of the
building, including roof overhangs, shall be used to achieve alternating light
and dark building surfaces that will blend with similar contrasts found in the
surrounding natural vegetation.
7. Mechanical Equipment. Mechanical equipment may be placed on rooftops or
below a deck only if the equipment is not visible from the public right-of-way or
adjacent properties, except for solar collectors that are compatible with the roof
line and architecturally integrated with the structure.
8. Fencing. Hillside area perimeter fencing that is visible from off-site vantages,
except on side and rear yards that are directly adjacent to living areas on
adjacent lots, shall be of a semitransparent, rather than solid, design.
Semitransparent material includes, but is not limited to, wrought iron, split rail,
and four-inch square welded wire. In side and rear yards between living areas on
adjacent lots, solid, opaque fencing is allowed. However, the preference is for a
more naturalistic approach to screening in the side yards, with semi-transparent
fencing combined with landscaping, or landscaping alone.
D. Director’s Action. The director may grant exceptions to standards of this
section as set forth in Chapter 17.108 (Director’s Action), subject the following
additional findings:
1. Intent. The director, through a director’s action, may act to approve an
exception to the hillside requirements of this section only where the
applicant can provide clear and substantiated evidence that there is no
practical way to comply with the provisions and that no other feasible
alternatives will result in better implementation of other zoning regulations
or general plan policies while allowing reasonable use of sites subject to
hillside regulations.
2. Application Type. A hillside regulation less than required by this section
may be approved by city action on a plan for public facilities approved by
the council or on a specific plan, development plan under planned
development zoning, land division, use permit, or architectural review.
Where one of these types of applications is not otherwise required for the
proposed feature, an exception request shall be in the form of a director’s
action.
Page 209 of 412
Ordinance No. _____ (2026 Series) Page 20
O ______
3. Findings. Each director’s action to grant an exception to a required
hillside regulation shall be subject to each of the following findings,
regardless of the type of project application under which the request is
considered:
a. The proposed alternative complies with and furthers the intent of
this section; and
b. The proposed alternative provides a design solution that is
equivalent to or better than the standards prescribed in this section for
quality, effectiveness, durability, and safety; and
c. The location and design of the feature receiving the exception will
minimize impacts to scenic resources and will not hinder opportunities
for wildlife habitation, rest, and movement; and
d. The exception will not prevent the implementation of city-adopted
plans, nor increase the adverse environmental effects of implementing
such plans; and
e. There are circumstances applying to the site, such as size, shape,
or topography, which do not apply generally to land in the vicinity with
the same zoning, that would deprive the property of privileges enjoyed
by other property in the vicinity with the same zoning; and
f. The exception will not constitute a grant of special privilege—an
entitlement inconsistent with the limitations upon other properties in the
vicinity with the same zoning; and
g. The exception will not be detrimental to the public welfare or
injurious to other property in the area of the project; and
h. Site development cannot be feasibly accomplished with a redesign
of the project or redesign of the project would deny the property owner
reasonable use of the property. “Reasonable use of the property” in the
case of new development may include less development than indicated
by zoning. In the case of additional development on an already
developed site, “reasonable development” may mean no additional
Page 210 of 412

O ______
development considering site constraints and the existing
development’s scale, design, or density.
E. Process Requirements.
1. Minor Development Review. Except as provided in state law, hillside
Hillside development shall require approval of minor development review
from the city’s planning division.
2. Design Review. Except as provided in state law, plans Plans submitted
for hillside development shall be reviewed for consistency with the city’s
community design guidelines, this section, and general development
standards of the zoning regulations. (Ord. 1705 § 17, 2021; Ord. 1650 § 3

SECTION 11. Title 17 ZONING REGULATIONS: Section 17.70.120 Lot
coverage is hereby amended as follows:
17.70.120 Lot coverage.
A. Purpose and Application. As defined in Chapter 17.158 (General Definitions),
lot coverage is the ratio of the total area of a lot covered by the footprint of all
structures to the net lot area, typically expressed as a percentage of the total lot
area, including all buildings, decks, balconies, porches, accessory structures and
accessory dwellings, and similar architectural features. Maximum coverage shall
be as provided in the specific property development standards for the various
zones in Chapters 17.12 through 17.60, inclusive.

O ______
B. Excluded from Lot Coverage. The following structures shall be excluded from
the lot coverage calculation:
1. Uncovered decks, porches, landings, balconies, and stairways that are
thirty inches or less in height, as measured from the adjacent existing
grade.
Figure 3-12. Decks Excluded from Coverage
2. Roof eaves which project thirty inches or less from the structure are not
included in the determination of coverage.
3. Swimming pools and hot tubs that are not enclosed in roofed structures
or decks.
4. One small, nonhabitable accessory structure under one hundred twenty
square feet and under seven feet high. Any additional structures above
quantity of one shall be included in lot coverage.
5. The first Up to eight hundred square feet of an accessory dwelling unit
lot coverage. Any additional square footage of an accessory dwelling unit
lot coverage shall be subject to applicable requirements included in lot
coverage. (Ord. 1705 §§ 17, 23, 2021; Ord. 1677 § 2, 2020; Ord. 1657 § 9,
2019; Ord. 1650 § 3 (Exh. B), 2018)
SECTION 12. Title 17 ZONING REGULATIONS: Section 17.70.170 Setbacks is
hereby amended as follows:
17.70.170 Setbacks.
Page 212 of 412
Ordinance No. _____ (2026 Series) Page 23
O ______
A. Purpose. This section establishes standards for the measurement of
setbacks and required setback areas. These provisions, in conjunction with other
applicable provisions of the zoning regulations, are intended to help determine
the pattern of building masses and open areas within neighborhoods. They also
provide separation between combustible materials in neighboring buildings.
Setback areas are further intended to help provide landscape beauty, air
circulation, views, and exposure to sunlight for both natural illumination and use
of solar energy.
B. Measurement of Setbacks.
1. General. All setback distances shall be measured at right angles from
the designated property line to the building or structure, and the setback
line shall be drawn parallel to and at the specified distance from the
corresponding front, side, or rear property line. Exception: Where the front
property line is located beyond the curb (i.e., within a street or common
driveway), the front setback is defined as the minimum distance between a
structure and the edge of curb.
2. Building Height and Setbacks. The height of a building in relation to
setback standards is the vertical distance from the ground to the top of the
roof, measured at a point that is a specific distance (the setback distance)
from the property line. Height measurements shall be based on the existing
topography of the site before grading for proposed on-site improvements.
Where building height is linked to a minimum setback, that setback shall
apply to the building incrementally and shall not require a clear-to-sky
setback for the entire building. Rather, the setback requirements allow the
building to be stepped back incrementally consistent with the required
setback distance based on building height.
3. Sloped Lots. For sloped lots, the measurement shall be made as a
straight, horizontal line from the property line to the edge of the structure,
not up or down the hill slope.
4. Flag Lots. For flag lots, the pole portion of the parcel shall not be used
for defining setback lines.
Page 213 of 412
Ordinance No. _____ (2026 Series) Page 24
O ______
C. Allowed Projections into Required Setback Areas. The following features are
allowed projections into required setback areas:
1. Utility Structures. Adequately screened components of public utility
systems may be located within front and street side setbacks when
approved by director’s action.
2. Fences, Walls, and Hedges. Fences, walls, and hedges may occupy
setbacks to the extent provided in Section 17.70.070 (Fences, Walls, and
Hedges). Vegetation may also be controlled by the California Solar Shade
Control Act.
3. Arbors and Trellises. Arbors and trellises may occupy setbacks subject
to the extent provided in Section 17.70.070 (Fences, Walls, and Hedges).
Arbors and trellises shall not be connected to or supported by a building,
nor be designed to support loads other than vines or similar plantings. They
are not considered structures for zoning purposes and shall not be used as
patio covers.
4. Signs. Signs in conformance with the sign regulations codified in
Chapter 15.40 (Sign Regulations) may occupy setbacks to the extent
provided in that chapter.
5. Architectural Features. The following and similar architectural features
may extend into a required setback:
a. Cornices, canopies, eaves, buttresses, chimneys, solar collectors,
shading louvers, reflectors, water heater enclosures, and bay or other
projecting windows that do not include usable floor space may extend
no more than thirty inches into a required setback (see Figure 3-13:
Architectural Feature Projections into Required Setbacks).

O ______
b. Uncovered balconies, uncovered porches, and decks over thirty
inches in height may extend into the required setback not more than
four feet or one-half the required setback distance, whichever is less.
Fire escapes, exit stairs, or other required exits may be required to
meet greater setbacks to comply with building code requirements.
c. Planters and similar features (e.g., patios and decks) less than thirty
inches in height may be located within the required setbacks.
6. Mechanical Equipment. Mechanical equipment shall comply with
required setbacks, with the following exceptions:
a. Ground-mounted heating and air conditioning equipment, and
tankless water heaters shall be set back not less than thirty inches from
the side and rear property lines and shall comply with Chapter 9.12
(Noise Control).
b. Mechanical equipment serving swimming pools, spas, and water
features shall be set back not less than three feet from a side or rear
property line. All such equipment shall be acoustically shielded to
comply with Chapter 9.12 (Noise Control).
7. Trash Enclosures. Enclosures that have been approved in conjunction
with Development Review or a discretionary review process may be located
within a required side or rear setback, provided no part of the enclosure is
less than three feet from any right-of-way or adopted setback line.

O ______
8. Vehicle Parking. Vehicle parking in front yard areas (as defined in
Section 17.158.016: F Definitions) of residential properties shall conform to
Section 17.76.040 (Front Yard Parking). No person shall stop, park, or
leave standing any vehicle, whether attended or unattended, within any
front or street side setback or upon any unpaved surface as defined in this
section and Section 12.38.040 (Parking and Driveway Standards).
9. Unenclosed Parking Spaces in Side and Rear Setbacks. Unenclosed
parking spaces and parking aisles may be located within side and rear
setbacks. For residential properties, parking spaces may not be located
within the front yard area unless consistent with Section 17.76.040 (Front
Yard Parking).
10. Enclosed and Unenclosed Parking Spaces in Front and Street Side
Setback Prohibited. In no case shall an enclosed parking space or required
parking space from which vehicles exit directly onto the street be located
less than twenty feet from the street right-of-way or property line, except as
provided in subsection D (Exceptions to Setback Requirements) of this
section, or as provided in Section 17.76.040(D) (Single Car Garages and
Single Car Parking). In no case shall a parking space encroach on a public
sidewalk.
11. Landscaping in Setbacks. Required setbacks with city-required
landscape plans and stormwater facilities shall be landscaped and
maintained in compliance with approved plans.
12. Second Story Setback in R-1 Zone. Up to fifty percent of the upper
story side wall may align with the lower floor wall, provided such alignment
occurs within the rear half of the structure (see Figure 3-14: Second Story
Setback Allowed Projection).

O ______
D. Exceptions to Setback Requirements.
1. Exceptions Entitled to Property Due to Physical Circumstances.
a. Front and/or Street Side Setback Averaging in Developed Areas.
Where these zoning regulations require front and/or street side
setbacks and where buildings have been erected on at least one-half of
the lots in a block as of the effective date of the regulations codified in
this section, the minimum required front and/or street side setback shall
be the average of the front and/or street side (as applicable) setback of
the developed lots, but in no case less than ten feet nor more than
would otherwise be required. Averaging does not apply to enclosed
parking structures.
b. Reduced Front or Street Side Setback for New Structure Providing
Additional Creek Setback. Where a new structure provides a rear or
side creek setback larger than required by these Zoning Regulations,
the required front and/or street side setback, respectively, shall be
reduced by one foot for each one foot of additional creek setback, so
long as the front and street side setback is at least one-half that
required by the zone in which the property is located. Refer to the front
and street side setback standards for each zone in Chapters 17.12
through 17.60, inclusive.
c. Setbacks Adjacent to an Alley. The standards required for interior
side and rear setbacks shall apply along alleys. However, zero setback
is allowed for required surface parking spaces.
Page 217 of 412
Ordinance No. _____ (2026 Series) Page 28
O ______
d. Rear Setback on Through Lots. On through lots, the minimum rear
setback shall be the equivalent to the minimum required front setback.
2. Discretionary Exceptions. Discretionary exceptions to setback
requirements shall require a director’s action and meet the findings required
for a director’s action (Chapter 17.108), as well as any findings indicated
below for an individual exception.
a. Reduced Front and Street Side Setbacks. Upon approval of a
director’s action, or in conjunction with tandem parking approval, the
director may allow front and/or street side setbacks to be reduced to
zero for unenclosed parking spaces. Front and street side setbacks
may be reduced to ten feet for structures, including side-loaded
carports and garages. However, no driveway shall be less than 18 feet
six inches deep, as measured from the sidewalk to face of a garage, or
where no sidewalk exists, the outer edge of the street, to accommodate
a parked car in the driveway without overhanging onto the public right-
of-way.
b. Variable Front Setbacks in Subdivisions. In new residential
subdivisions, the review authority may approve variable front setbacks,
to be noted on the approved map, provided the average of the front
setbacks on a block is at least fifteen feet and no front setback is less
than ten feet. Garages or carports that back directly onto the public
right-of-way shall maintain a minimum setback of at least eighteen feet
six inches, as measured from the sidewalk or where no sidewalk exists,
as measured from the outer edge of the public right-of-way, to
accommodate a parked car in the driveway without overhanging onto
the public right-of-way.
c. Variable Side and Rear Setbacks in New Subdivisions. In new
residential subdivisions, the review authority may approve exceptions to
the side and rear setback standards, with the exceptions to be noted on
the map, provided a separation of at least ten feet between buildings on
adjacent lots will be maintained and an acceptable level of solar
exposure will be guaranteed by alternative setback requirements or
private easements to ensure the development will comply with solar
Page 218 of 412
Ordinance No. _____ (2026 Series) Page 29
O ______
access standards of General Plan Conservation and Open Space
Element Policy 4.5.1.
d. Other Setback Variations in Previously Subdivided Areas. Upon
approval of a director’s action, the director may allow side and rear
setbacks to be reduced to zero under either of the following
circumstances:
i. When there exists recorded agreement, to the satisfaction of the
city attorney, running with the land to maintain at least ten feet of
separation between buildings on adjacent parcels and the
development will comply with solar access standards of General
Plan Conservation and Open Space Element Policy 4.5.1; or
ii. When the reduction is for either a minor addition to an existing
legal structure that is nonconforming with regard to side and rear
setback requirements or for a detached single-story accessory
structure; provided, that all such minor additions and new accessory
structures shall comply with applicable provisions of Title 15, Building
and Construction (see also Chapter 17.92, Nonconforming
Structures) and the director makes the following findings:
(a) In the case of a minor addition, that the minor addition is a
logical extension of the existing nonconforming structure;
(b) In the case of a detached single-story accessory structure
(either new or replacing a previously approved nonconforming
structure), that the accessory structure is consistent with the
traditional development pattern of the neighborhood and will have
a greater front and/or street side setback than the main structure;
(c) That adjacent affected properties will not be deprived of
reasonable solar exposure, and the development will comply with
solar access standards of General Plan Conservation and Open
Space Element Policy 4.5.1;
(d) That no useful purpose would be realized by requiring the full
setback;
Page 219 of 412
Ordinance No. _____ (2026 Series) Page 30
O ______
(e) That no significant fire protection, emergency access,
privacy, or security impacts are likely from the addition; and
(f) That it is impractical to obtain a ten-foot separation easement
in compliance with subsection (D)(2)(d)(ii)(a) of this subsection.
e. Side and Rear Setback Building Height Exceptions. Upon approval
of a director’s action, the director may allow exceptions to the side and
rear setback standards provided in Article 2 for each zone. Such
exceptions may be granted in any of the following and similar
circumstances, but in no case shall exceptions be granted for less than
the minimum setback required:
i. When the property that will be shaded by the excepted
development will not be developed or will not be deprived of
reasonable solar exposure, considering its topography and zoning;
ii. When the exception is of a minor nature, involving an insignificant
portion of total available solar exposure;
iii. When the properties at issue are within an area where use of
solar energy is generally infeasible because of landform shading;
iv. When adequate recorded agreement running with the land exists
to protect established solar collectors and probable collector
locations;
v. When the property to be shaded is a street;
vi. Where no significant fire protection, emergency access, privacy
or security impacts are likely to result from the exception.
vii. The development will comply with solar access standards of
General Plan Conservation and Open Space Element Policy 4.5.1.
Any other exception to the height limits requires approval of a variance as
provided in Chapter 17.114 (Variances). For height limits of signs, see Chapter
15.40, Sign Regulations. (Ord. 1705 §§ 17, 27, 28, 2021; Ord. 1657 § 10, 2019;

implementing numerous changes to the Mobilehome Residency Law, primarily
repealing an exemption to rent control measures for long-term mobile home leases; and
WHEREAS, on October 10, 2025, Governor Newsom approved AB 1061 to
allow minor urban lot splits on properties located in a historic district; and
WHEREAS, the City of San Luis Obispo desires to update Title 16 (Subdivision
Regulations) and Title 5 (Licenses, Permits, and Regulations) so that they may be
consistent with current state law; and
WHEREAS, a number of changes have been identified in order to clarify or
change processes related to housing development to more efficiently implement policies
and programs of the City of San Luis Obispo’s General Plan that are implemented
through Title 17 (Zoning Regulations) and align with state housing law; and
WHEREAS, the Planning Commission of the City of San Luis Obispo conducted a
public hearing in the Council Chamber of City Hall, 990 Palm Street, San Luis Obispo,

Planning Commission Resolution No. PC-1118-2026
CODE-0149-2026 (Citywide)
Page 2
SECTION 1. Findings. Based upon all evidence, the Planning Commission makes
the following findings:
1. The proposed amendments to Titles 16, 17, and 5 will not cause significant health,
safety, or welfare concerns since the amendments are consistent with the General
Plan and directly implement City goals and polices.
2. The proposed amendments to Title 17 are consistent with the 6th Cycle Housing
Element in promoting Goal 5 (Housing Variety) and Goal 6 (Housing Production).
3. The proposed amendments to Title 16, 17, and 5 are consistent with state law.
SECTION 2. Environmental Determination. The proposed code amendments to
Title 16, Title 17, and Title 5 of the Municipal Code have been assessed in accordance
with the authority and criteria contained in the California Environmental Quality Act
(CEQA), the State CEQA Guidelines, and the environmental regulations of the City.
Specifically, the proposed amendments have been determined to be exempt from further
environmental review pursuant to CEQA Guidelines Section 15061(b)(3), the “Common
Sense” exemption, because the activity is covered by the general rule that CEQA applies
only to projects which have the potential for causing a significant effect on the
environment, and it can be seen with certainty that there is no possibility that the activity
in question may have a significant effect on the environment. Individual discretionary
developments will still be required to conduct environmental analyses as appropriate. The
proposed code amendments pertaining to ADUs and JADUs are also exempt under
Public Resourced Code Section 21080.17 that applies to local ordinances implementing
state regulations related to accessory dwelling units.
SECTION 3. Action. The Planning Commission hereby recommends to the City
Council the introduction and adoption of an ordinance to amend Title 16 (Subdivision
Regulations), Title 17 (Zoning Regulations), and Title 5 (Licenses, Permits, and
Regulations) of the City’s Municipal Code regarding accessory and junior accessory
dwelling units, urban lot splits, mobile homes, and other clarifications and changes to
regulations associated with housing, as set forth in Attachments B, C, and D.

following roll call vote:

The proposed amendments to Title 5, Title 16, and Title 17 are consistent with
various policies under the City’s 6th Cycle Housing Element:
•Policy 2.4 – encourage housing production for all financial strata of the City’s
populations…
•Policy 6.8 – to meet the 6th Cycle RHNA production targets, the City will
support residential infill development and promote a higher residential density
where appropriate
•Policy 8.1 – encourage housing development that meets a variety of special
needs, including large families, single parents, disabled persons, the elderly,
students, veterans, farmworkers, the homeless…
Summary
Proposed amendments would:

•Address inconsistencies between state law and the code
•Remove barriers to housing development
•Incorporate miscellaneous changes that address conflicts within the
Municipal Code and other changes
Accessory & Junior Accessory Dwelling Units
Clarify height and setback limits for ADUs

Defer to underlying zone standard for maximum ADU height
•Potentially increase ADU development in multifamily zones
Remove provision regarding “two-step” to “one-step process”
•Introduced in 2024 code update – can be interpreted as
inconsistent with state law

exempt from discretionary review
“Attached” ADU v. “Detached” ADU
•Adds language to definition to differentiate between attached and
detached ADUs
Lot Coverage Clarification
•Per state law, the first 800 square feet of ADU building footprint is

districts
•Minor urban lot splits are still prohibited on sites that are listed as
historic resources (by either the state or city)
•Minor urban lot splits are still prohibited if the alteration or
demolition of a historic resource is required to facilitate the
subdivision

maintain consistency with state law
Mobile Homes
Per AB 2782, the City is no longer required to exclude long-term space
leases from its mobile home park rent stabilization ordinance (SLOMC
5.44)

remove this exemption
Staff identified a provision of SLOMC 5.44 regarding an exemption
process for a section of this chapter that no longer exists

SLOMC 17.140.040 does not specify whether to use fractional density
units or “dwelling units per acre” when calculating density bonus units.
•Allows an applicant to maximize the number of market-rate units
they can while limiting the number of affordable units they must
provide
Staff proposes an amendment requiring the consistent use of either
fractional density units or “dwelling units per acre” as provided in
Density Bonus Law (Section 65915) when calculating density bonus
units
