Code Regs. Title 24, Part 1); 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.
