AN ORDINANCE OF THE CITY COUNCIL OF THE CITY OF SAN LUIS
OBISPO, CALIFORNIA, ADOPTING LOCAL AMENDMENTS TO PART 6
OF THE BUILDING CONSTRUCTION AND FIRE PREVENTION CODE,
2023
WHEREAS, greenhouse gas accumulation in the atmosphere as the result of
human activity is the primary cause of the global climate crisis; and
WHEREAS, in California alone, the initial impacts of climate change have resulted
in unprecedented disasters with tremendous human, economic, and environmental costs
and;
WHEREAS, 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; and
WHEREAS, the State of California enacted Assembly Bill (AB) 1279 to require
statewide carbon neutrality "as soon as possible," but no later than 2045; and
WHEREAS, City of San Luis Obispo residents and businesses have repeatedly
identified climate action as a top community priority; and
WHEREAS, Resolution 11159 (2020 Series) adopts the City of San Luis Obispo
Climate Action Plan for Community Recovery, which includes a communitywide goal of
carbon neutrality by 2035 and sector specific goal of reducing emissions from existing
buildings by half by 2030; and
WHEREAS, Resolution 11381 (2022 Series) reaffirmed these communitywide and
sector specific goals; and
WHEREAS, the inventoried greenhouse gas emissions in the City of San Luis
Obispo come from a variety of sources, primarily transportation and energy use in
buildings and facilities; and
WHEREAS, in order to achieve carbon neutrality, existing sources of greenhouse
gas emissions need to be substantially reduced or eliminated; and
WHEREAS, Public Resources Code Section 25402.1 (h)(2) allows local agencies

O 1736
WHEREAS, the California Energy Codes and Standards Statewide Utility
Program, has determined specific modifications to the 2022 State Energy Code for each
climate zone that are cost-effective; and that such modifications will result in designs that
consume less energy than they would under the 2022 State Energy Code; and
WHEREAS, staff has reviewed the “2022 Code Cycle: Custom Cost Effectiveness
Analysis - City of San Luis Obispo” existing building cost-effectiveness study, and finds it
sufficient to illustrate compliance with the requirements set forth under California
Administrative Code Chapter 10-106; and
WHEREAS, based on these studies, the City finds the proposed local
amendments to the 2022 California Energy Code to be cost-effective and consume less
energy than permitted by Title 24, Part 6; and
WHEREAS, the 2022 California Energy Code offers compliance options that were
established through the public rulemaking process of the code update; and
WHEREAS, the Council expressly declares that the proposed amendments to the
Energy Code are reasonably necessary because of local climatic, topological, and
geological conditions; and
WHEREAS, the requirements specified in this Ordinance were reviewed via public
comment and through a publicly noticed public hearing process.
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
standards for single-family residential retrofits including major additions and alterations
that exceed minimum 2022 Title 24 Part 6 requirements.
SECTION 2. Adoption. The local amendments to Part 6 of the City of San Luis
Obispo Building Construction and Fire Prevention Code, 2023 (SLOMC Section
15.02.060) as specified in Exhibit A, are hereby adopted by the City of San Luis Obispo
to be codified under Chapter 15.02.060 and Chapter 15.04.065. The Council hereby
adopts the recitals herein as separate and additional findings of fact in support of adoption
of the ordinance.
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, section, 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.
Ordinance No. 1736 (2024 Series) Page 3
O 1736
SECTION 5. 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. 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.
2. 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, 1995, and 2023. 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 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.
3. 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.
Ordinance No. 1736 (2024 Series) Page 4
O 1736
4. 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 to increase the efficiency of existing buildings in the
City to reduce greenhouse gas emissions.
5. Failure to address and substantially reduce greenhouse gas emissions creates
an increased risk to the health, safety, and welfare of City residents.
6. The standards imposed by this Ordinance are necessary because of local
climatic, geological, or topographical conditions evidenced above and are cost-
effective, as supported by the “2022 Code Cycle: Custom Cost Effectiveness
Analysis - City of San Luis Obispo” cost effectiveness study prepared by the
California Energy Codes and Standards Statewide Utility Program. Specifically,
the City finds that there are at least five cost effective measure packages:
x Package 1, installing the efficiency measure of R-30 Floor Insulation would
save energy relative to the base code and would achieve a benefit to cost
ratio of 1.4 on an on-bill basis.
x Package 2, installing the efficiency measure of R-19 Floor Insulation would
save energy relative to the base code and would achieve a benefit to cost
ratio of 1.4 on an on-bill basis.
x Package 3 to installing a Heat Pump Water Heater (HPWH), would save
energy relative to the base code and would achieve a benefit to cost ratio
of 1.6 on a “Long-term System Cost” (LSC basis).
x Package 4, Heat Pump Space Heater, would save energy relative to the
base code and would achieve a benefit to cost ratio of 4.2 on an LSC basis.
x Package 5 to install PV + Electric Ready Pre-Wiring would save energy
relative to the base code and would achieve a benefit to cost ratio of 1.4 on
an on-bill basis.

O 1736
SECTION 6. 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 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. The Reach Code approval process requires that the City determines that the
local standards will require buildings to use no more energy than current
statewide requirements. Furthermore, the California Energy Commission
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.
SECTION 7. Violations. Violation of the requirements of this Ordinance shall be
considered, at the City’s election, an infraction of the City of San Luis Obispo Municipal
Code punishable by all sanctions prescribed in Chapter 1.12, or an administrative
violation punishable as provided under Chapter 1.24.
SECTION 8. Effective Date. Pending approval by the California Energy
Commission, this Ordinance shall be effective on January 1, 2025.

SECTION 9. Ordinance Summary. 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.
