NOW, THEREFORE, THE TOWN COUNCIL OF THE TOWN OF LOS GATOS DOES HEREBY
ORDAIN AS FOLLOWS:
Section 1.
3 of 72
Ordinance 2380 December 2,2025
LEGISLATIVE FINDINGS
A. The recitals set forth above are true and correct and are incorporated into this
ordinance by reference as if fully set forth herein.
B. In accordance with Health and Safety Code Sections 17958 and following,the
Town Council finds that local amendments are reasonably necessary because of the following
local climatic, geological, or topographical conditions:
1. Climatic:The Town of Los Gatos experiences low humidity, high wind, and warm
temperatures during the summer months, creating conditions that are particularly conducive to
the ignition and spread of grass, brush, and structure fires.
2. Geologic:The Town of Los Gatos is situated adjacent to active earthquake faults
capable of producing substantial seismic events.
3. Topographic: The Town of Los Gatos is partially located in rugged, steep, and heavily
vegetated hillsides accessible over limited roadways that are steep, narrow, and circuitous.
4. Topographic: The Town of Los Gatos is divided by a creek, freeways, and other traffic
corridors, and is partially located in hillside areas with limited access. The occurrence of a major
earthquake would significantly impact the ability of fire crews to respond to emergencies
should one or more bridges collapse or be substantially damaged. Additionally,fire suppression
capabilities will be severely limited should the water system be extensively damaged during a
seismic event.
5. Climatic: Climate change exacerbates fire risk in the Town. Greenhouse gas emissions
contribute to climate change. The State of California has outlined specific steps to reduce
greenhouse gas emissions to prevent these negative impacts of a changing climate. This allows
local governments to achieve greenhouse gas emission reductions with a climate-positive
impact by powering buildings from clean electricity. The proposed Reach Code would reduce
the amount of greenhouse gas emissions produced by the Town's existing housing and
encourage the use of cleaner sources of energy that are in line with Mitigation Measure GHG-1
of the General Plan Environmental Impact Report.These climatic conditions along with the
greenhouse emissions generated from existing structures require exceeding the energy
standards for construction established in the 2025 California Buildings Standards Code.
6. Due to the Town's local climatic, geological, geographical, and topographical
conditions, mitigation measures are necessary, such as automatic fire suppression systems,
communications systems, access to buildings, seismic protection, safety controls for hazardous
materials, and other safeguards to minimize the risks to citizens,firefighters, and property
resulting from the severity of a fire threat and potential delays in responding to such threats.
C. In accordance with Health and Safety Code Sections 17958, 17958.5, and
17958.7, the Town Council finds that the AC to heat pump and electric-readiness changes to
4 of 72
Ordinance 2380 December 2, 2025
building standards affecting residential units in the 2025 California Energy Code and 2025
California Green Building Standards Code are necessary to implement the Town's local code
amendment adding an AC to heat pump and electric-readiness requirement, and that the local
code amendment:
a. Is adopted to align with the Town's General Plan, specifically Section 8.5,
"Climate Change/Greenhouse Gas Emissions," of Chapter 8, "Environment and
Sustainability Element," and Policy 9.6, "Energy Conservation and Renewable
Energy Use," adopted on June 30, 2022; and
b. Permits mixed-fuel residential construction consistent with federal law; and
c. Incentivize all-electric construction, as part of the Town's adopted greenhouse
gas emissions reduction strategy in its 2012 Sustainability Plan.
In accordance with Public Resources Code Section 25402.1(h)(2) and Section 10-106 of the 2025
California Administrative Code (Cal. Code Regs. Title 24, Part 1), the Town Council finds that the
Town's AC to heat pump reach code modifications to the energy standards in the California
Green Building Standards Code (Cal. Code Regs. Title 24, Part 11) ("CALGreen") are cost-
effective, and that the modifications will require the diminution of energy consumption levels
permitted by the Energy Code.
7. The Town Council finds that all codes adopted herein related to residential structures
are substantially equivalent to prior local amendments, or are related to home hardening and
wildfire safety, consistent with the requirements of Assembly Bill 130.
