San Luis Obispo Council moves to introduce 2025 building and fire code ordinances, including limited local amendments

San Luis Obispo City Council voted unanimously to introduce two ordinances that would adopt the 2025 California Building Standards Code and the 2025 California Energy Code with a small set of local amendments.

Community Development Director Timmy Twain told the council staff's recommendation "is generally a pretty routine item that the city council considers every few years" and outlined that state law AB 130 establishes a moratorium on many local residential amendments through June 2031, with narrow exceptions for emergency standards, home‑hardening, grandfathered local standards, and general‑plan alignment. The staff recommendation seeks to readopt existing local standards that qualify under those exceptions and add two limited local amendments: clarification of energy retrofit applicability for residential remodels and a fire‑sprinkler density change tied to certain EV charging installations in parking structures.

Fire Marshal Josh Daniel described the WUI code's home‑hardening and defensible‑space provisions and noted an emergency express term (EF0125) signed Oct. 15 by the state fire marshal that removed a prior July 1, 2008 exemption for some structures. "We recommend staff adopt this as is," Daniel said, arguing the city should implement the code and monitor how it works before making further local adjustments.

On energy measures, staff explained the 2025 energy code tightens water‑heating and HVAC standards, requires buildings to be electric‑ready with updated solar/battery and storage readiness, and advances EV charging and embodied‑carbon rules for certain large projects. For residential remodels and additions, staff said the city is moving from a square‑foot trigger to valuation triggers: projects with a valuation of $100,000 would trigger electric‑readiness measures and projects at $200,000 would trigger energy‑efficiency requirements. Staff said cost‑effectiveness analyses justify the findings needed for those local amendments.

Councilmembers asked staff about the pending zone‑0 (0–5 feet) defensible‑space rules from the Board of Forestry, outreach materials and an instructional video, and why additional sprinklers for some EV charging areas are being proposed. Daniel cited NFPA guidance and described the sprinkler change as intended to create a large water curtain to control smoke and protect parking structures and firefighters, saying "it's just copious amounts of water" to manage EV fire risks.

Staff outlined implementation steps including a unified web page, a home‑hardening checklist and video, a fee‑based voluntary inspection program, and available technical assistance and rebate programs through partners such as Central Coast Community Energy. The fire department also reported a $60,000 FEMA grant to seed two community risk‑reduction intern positions to support outreach and inspections.

Vice Mayor Shoresman moved to introduce staff's recommendations; Councilmember Francis seconded. The clerk called the roll and the motion to introduce the ordinances passed 5-0. Staff said the ordinances will return for a second reading in December; final adoption requires subsequent state review where applicable.
