community greenhouse gas emissions as the result of on-site energy use; and
WHEREAS, a first reading of Ordinance 1668 (2019 Series) to establish local
amendments to the California Building Code was approved by Council, but the ordinance was not
adopted.
NOW, THEREFORE, BE IT ORDAINED by the Council of the City of San Luis Obispo
as follows:
SECTION 1. Purpose. It is the purpose and intent of this Ordinance to establish the Clean
Energy Choice Program, including standards for new buildings to exceed minimum 2019 Title 24
Part 6 requirements.
SECTION 2. Adoption. The 2019 California Building Code, Title 24, Part 6, is hereby
adopted by the City of San Luis Obispo with local amendments to be codified under Chapter 15.04
as specified in Exhibit A. The Council hereby adopts the recitals herein as separate and additional
findings of fact in support of adoption of the ordinance.

O 1684
SECTION 3. Severability. If any word, phrase sentence part, section, subsection or other
portion of this amendment or any application thereof to any person or circumstance is declared
void, unconstitutional, or invalid for any reason, then such word, phrase, sentence, part, sect ion,
subsection, or other portion, or the prescribed application thereof, shall be severable, and the
remaining provisions of this amendment, and all applications thereof, not having been declared
void, unconstitutional or invalid, shall remain in full force and effect. The City of San Luis Obispo
hereby declares that it would have passed this amendment and each section, subsection sentence,
clause and phrase of this amendment, irrespective of the fact that any one or more sections,
subsection, sentences, clauses or phrases is declared invalid or unconstitutional.
SECTION 4 - Findings. The City Council finds that each of the changes or modifications
to measures referred to therein are reasonably necessary because of local climatic, geological, or
topographical conditions in the area encompassed by the boundaries of the City of San Luis
Obispo, and the City Council adopts the following findings in support of local necessity for the
changes or modifications:
1. As a city located on the California Central Coast, San Luis Obispo is vulnerable to the
effects of sea level rise and resultant flooding within the San Luis Creek watershed,
and human activities releasing greenhouse gases into the atmosphere cause increases
in worldwide average temperature, which contribute to melting of glaciers and thermal
expansion of ocean water – resulting in rising sea levels.
2. San Luis Obispo is already experiencing the repercussions of excessive greenhouse gas
emissions as rising sea levels and severe weather events threaten the City’s nearby
shoreline and infrastructure and cause significant erosion leading to infrastructure
failures including the Mud Creek slide resulting in closure of Highway 1 for repairs,
and economic impacts to surrounding communities.
3. San Luis Obispo is situated along a wildland-urban interface and has been identified as
a Community at Risk from wildfire and is extremely vulnerable to wildfires and
firestorms, and human activities releasing greenhouse gases into the atmosphere cause
increases in worldwide average temperature, drought conditions, vegetative fuel, and
length of fire seasons- contributing to the likelihood and consequences of fire.
4. The City of San Luis Obispo is situated at the base of a watershed of the Santa Lucia
Mountains and flooding of San Luis, Chorro, Stenner, Old Garden,
and Brizzolara Creeks results in conditions rendering fire department vehicular traffic
unduly burdensome or impossible, as witnessed in major floods that occurred in 1952,
1961, 1969, 1973, 1978, 1982, and 1995. Furthermore, flood conditions described
above create the potential for overcoming the ability of the fire department to aid or
assist in fire control, evacuations, rescues and other emergency task demands inherent
in such situations. The resulting overburdening of fire department personnel may cause
a substantial or total lack of protection against fire for the buildings and structures
located in the City of San Luis Obispo. The afore-described conditions support the
imposition of fire protection requirements greater than those set forth in the California
State Building Standards Code and, in particular, support the imposition of more
restrictive requirements than set forth in the California Energy Code for the purpose
of reducing the City’s contributions to Greenhouse Gas Emissions resulting in a
warming climate and related severe weather events.
Ordinance No. 1684 (2020 Series) Page 4
O 1684
5. The aforementioned flood and rain events result in conditions wherein stormwater can
inundate the wastewater treatment system as witnessed in major floods that occurred
in 1952, 1961, 1969, 1973, 1978, 1982, and 1995. Furthermore, rain events and flood
conditions described above create a condition referred to as Inflow and Infiltration (I/I)
that allow rain and flood waters to flow and/or seep into the wastewater system and
overcome the ability of the wastewater collection system and Water Reclamation
Facility (WRF) to convey and treat sewage. The resulting overburdening of the
wastewater system can result in threats to public health, public and private property
and water quality and violations and fines from the State of California, the
Environmental Protection Agency (EPA) or others. To the extent that climate change
has the potential to make these conditions worse, more restrictive Energy Code
requirements to achieve reduced greenhouse gas emissions are necessary.
6. The City of San Luis Obispo is situated near three major faults each capable of
generating earthquakes with a magnitude of 7.5. These are the San Andreas to the east
of the City, the Nacimiento-Rinconada that crosses Hwy 101 north of the City then
parallels the City to the east, and the Hosgri to the West. Other faults of importance
are the Huasna and West Huasna to the Southeast of the City, the San Simeon to the
Northwest, and the Edna and Edna Extended faults which enter the southern areas of
the City. In as much as these faults are included as major California earthquake faults,
which are subject to becoming active at any time, the City of San Luis Obispo is
particularly vulnerable to devastation should such an earthquake occur. The potential
effects include isolating the City of San Luis Obispo from the North and South due to
the potential for collapsing of freeway overpasses or a slide on both the Cuesta and
Ontario Grades and the potential for horizontal or vertical movement of the Edna fault
rendering surface travel across the southern extremities of the city unduly burdensome
or impossible. Additional potential situations inherent in such an occurrence include
loss of the City's two main water sources (the Salinas and Whale Rock reservoirs),
broken natural-gas mains causing structure and other fires, leakage of hazardous
materials, the need for rescues from collapsed structures, and the demand for first aid
and other medical attention to large numbers of people. As a result, the City is pursuing
a policy to discourage additional natural gas extensions and the related, expanded risk
of gas leaks and explosions during seismic events for the protection of human life and
the preservation of property in the event of such an occurrence.
7. That seasonal climatic conditions during the late summer and fall create numerous
serious difficulties in the control and protection against fire situations in the City of San
Luis Obispo. The hot, dry weather in combination with Santa Lucia (offshore) winds
frequently results in wildland fires in the brush-covered slopes on the Santa Lucia
Mountains, San Luis Mountain, and the Irish Hills areas of the City of San Luis
Obispo. The aforementioned areas surround the City. When a fire occurs in said areas,
such as occurred in 1985 when the Los Pilitas fire burned six days and entered the City
and damaged many structures, the entirety of local fire department personnel is required
to control, monitor, fight and protect against such fire situations in an effort to protect
life and preserve property and watershed land. The same climatic conditions may result
in the concurrent occurrence of one or more fires in the more populated areas of the
City without adequate fire department personnel to protect against and control such a
situation. Therefore, the above-described findings support the imposition of measures
Ordinance No. 1684 (2020 Series) Page 5
O 1684
to increase the efficiency of new buildings in the City and reduce Green House Gas
emissions from carbon, and support reducing the amount of natural gas distributed and
used throughout the City.
SECTION 5 CEQA. This ordinance is categorically exempt from CEQA because it is an
action taken by a regulatory agency for the purpose of protecting the environment (CEQA
Guidelines Section 15308). In addition, this ordinance is exempt from CEQA under the general
rule, 15061(b)(3), on the grounds that these standards are more stringent than the State energy
standards, there are no reasonably foreseeable adverse impacts, and there is no possibility that the
activity in question may have a significant effect on the environment.
The following findings are made in support of these determinations:
1. The purpose of the City’s Clean Energy Choice Policy and the implementation of a
Reach Code is to reduce the amount of greenhouse gas emissions in the City of San
Luis Obispo that are produced from buildings.
2. All electric buildings constructed in the City of San Luis Obispo consistent with the
Clean Energy Choice Policy and implementation of a Reach Code will reduce
greenhouse gas emissions, improve indoor air quality, and reduce the risk of
catastrophic infrastructure failure, including explosions and fires caused by breaks and
leaks in the natural gas distribution system as a result of upset conditions due to
deferred maintenance or following an earthquake.
3. The Reach Code approval process requires that City determine it is cost effective and
that the local standards will require buildings to use no more energy than current
statewide. Furthermore, the CEC approval process requires that the City make the
findings as part of its approval process. Therefore, the Reach Code standards can only
go into effect if they protect the environment by making buildings more efficient and
in a cost-effective manner.
4. The City’s Clean Choice Energy Program enables property owners and developers to
take advantage of a statewide effort to build a clean, efficient, and reliable grid to serve
expanding energy needs across the State of California.
5. The Intergovernmental Panel on Climate Change estimates that global emissions need
to be reduced by 45 percent from 2010 levels by 2030, and 100 percent by 2050 to
prevent global catastrophe. However, due to the lack of coordinated action or a
comprehensive plan to address this threat at a national level, cities and states across the
United States must lead the way.
SECTION 6. Violations. Violation of the requirements of this Ordinance shall be
considered an infraction of the City of San Luis Obispo Municipal Code, punishable by all the
sanctions prescribed in Chapter 1.12.
SECTION 7. Effective Date. This Ordinance shall be effective as of September 1, 2020.

SECTION 8. A summary of this ordinance, together with the names of Council members
voting for and against, shall be published at least five (5) days prior to its final passage, in The
New Times, a newspaper published and circulated in this City. This ordinance shall go into effect
at the expiration of thirty (30) days after its final passage.

A. Adoption of Codes and Applicability.
1. The City of San Luis Obispo hereby adopts the 2019 California Code of Regulations, Title
24, Part 6 (California Energy Code) with local amendments as set forth herein. The
provisions of such are hereby referred to, adopted, and made a part hereof as if fully set out
in this Chapter except as modified hereinafter. These regulations will be known as the City
of San Luis Obispo Energy Reach Code and all prior provisions are hereby superseded.
2. The effective date of this ordinance shall be September 1, 2020 and is applicable to new
construction buildings including those that are built after a demolition. The amendments
contained in 15.04.110 do not apply to Additions, Alterations, or Attached Accessory
Dwelling Units. Residential subdivisions in process of permitting or constructing initial
public improvements for any phase of a final map recorded prior to January 1, 2020 are
exempt, unless compliance is required by an existing Development Agreement. Additional
exemptions and exceptions are identified below.
3. Notwithstanding the requirements of this Chapter and the Council's Clean Energy Choice
Policy, and other public health and safety hazards associated with natural gas
infrastructure, natural gas may be allowed in a building otherwise subject to the
requirements of this ordinance if the authority responsible for entitling or permitting the
project makes any of the following findings:
a. That current limitations of electric power infrastructure in the vicinity of the project
site make it impossible to serve the project without significant upgrades, such as to
transformers or other distribution equipment, that are outside the scope of the
proposed project and would render it economically infeasible.
b. The proposed project would result in a de minimis use of natural gas that could be
offset, such as through a sequestration project or other proposal directly tied to the
development project.
c. Consistent with the purpose and intent of these regulations, the authority granting
approval to a project may permit the use of natural gas without requiring the
additional efficiency requirements or appliance pre-wiring if it is determined to be
necessary to serve public health, safety and welfare.
B. Amend Section 100.1(b) by adding the following definitions:
ALL-ELECTRIC BUILDING is a building that has no natural gas plumbing installed

order to comply with performance standards.
L. Amend Section 150.1(b)1 and 2 to read as follows:
1. Newly Constructed Buildings. The Energy Budget for newly constructed buildings or
newly constructed Detached Accessory Dwelling Units is expressed in terms of the Energy
Design Rating, which is based on TDV energy. The Energy Design Rating (EDR) has two
components, the Energy Efficiency Design Rating, and the Solar Electric Generation and
Demand Flexibility Design Rating. The Solar Electric Generation and Demand Flexibility
Design Rating shall be subtracted from the Energy Efficiency Design Rating to determine
the Total Energy Design Rating. The Proposed Building shall separately comply with the
Energy Efficiency Design Rating and the Total Energy Design Rating.
A. An All-Electric Building complies with the performance standards if both the Total
Energy Design Rating and the Energy Efficiency Design Rating for the Proposed
Building are no greater than the corresponding Energy Design Ratings for the Standard
Design Building.
B. A Mixed-Fuel Building complies with the performance standards if:
i. The Energy Efficiency Design Rating of the Proposed Building is no greater than
the Energy Efficiency Design Rating for the Standard Design Building;
ii. The Total Energy Design Rating of the Proposed Building is less than the Total
Energy Design Rating of the Standard Design Building by at least 9 for a single-
family dwelling unit and 9.5 for a multi-family dwelling unit.

Exception to Section 150.1(b)1.B.ii. Buildings with limited solar access are excepted if all of
the following are true:
1. The Total Energy Design Rating for the Proposed Building is no greater than the Total
Energy Design Rating for Standard Design Building; and
2. A photovoltaic (PV) system(s) meeting the minimum qualification requirements as
specified in Joint Appendix JA11 is installed on all available areas of 80 contiguous
square feet or more with effective annual solar access. Effective annual solar access
shall be 70 percent or greater of the output of an unshaded PV array on an annual basis,
wherein shade is due to existing permanent natural or manmade barriers external to the
dwelling, including but not limited to trees, hills, and adjacent structures; and
3. The Energy Efficiency Energy Design Rating for the Proposed Building is no greater
than the respective value for the Standard Design Building by the EDR margin in Table
150.1(b)1 below.

Exception to Section 150.1(b)1.: A community shared solar electric generation system, or
other renewable electric generation system, and/or community shared battery storage system,
which provides dedicated power, utility energy reduction credits, or payments for energy bill
reductions, to the permitted building and is approved by the Energy Commission as specified
in Title 24, Part 1, Section 10-115, may offset part or all of the solar electric generation system
Energy Design Rating required to comply with the Standards, as calculated according to
methods established by the Commission in the Residential ACM Reference Manual.
M. Amend Section 150.1(c) to read as follows:
Prescriptive Standards/Component Package. All-Electric Buildings that comply with the
prescriptive standards shall be designed, constructed, and equipped to meet all of the
requirements for the appropriate Climate Zone shown in TABLE 150.1-A or B. In TABLE
150.1-A and TABLE 150.1-B, a NA (not allowed) means that feature is not permitted in a
particular Climate Zone and a NR (no requirement) means that there is no prescriptive
requirement for that feature in a particular Climate Zone. Mixed-fuel buildings shall comply
with requirements of section 150.1(b). Installed components for All-Electric Buildings shall
meet the following requirements:
NOTE: The rest of the Section 150.1(c) applies without modifications but is not reproduced
here for brevity.
