Home My WebLink About102125-08.2 ADMINISTRATIVE STAFF REPORT 8.2 TO: Mayor and Town Council October 21, 2025 SUBJECT: Ordinance No. 2025-05, repealing existing Chapters 10-1 through 10-7, 10- 13 through 10-15, 10-18 and 10-19 of the Danville Municipal Code and adding new Chapters 10-1 through 10-7, 10-13 through 10-15, 10-18, 10-19 and 10-20 to the Danville Municipal Code adopting the 2025 California Building Codes BACKGROUND Every three years, the California Building Standards Commission (the “Commission”) adopts a new set of building codes. The latest set of codes were adopted by the Commission in 2025 and become effective January 1, 2026 (as will the proposed ordinance). Once adopted by the Commission, these codes become the minimum standard for construction throughout the state. Local agencies are authorized by law to adopt more stringent standards if they are based on environmental, geologic, topographic, or climatic conditions unique to that jurisdiction. Without any local action, the California codes are binding on local agencies. Even without making local changes, almost all jurisdictions adopt the California codes by reference to ensure consistency. The California codes proposed for adoption are:  2025 California Building Code  2025 California Residential Code  2025 California Electrical Code  2025 California Mechanical Code  2025 California Plumbing Code  2025 California Fire Code  2025 California Green Building Standards Code  2025 California Administrative Code  2025 California Energy Code  2025 California Referenced Standards Code  2025 California Historical Building Code  2025 California Existing Building Code  2025 California Wild-Urban Interface Code (new Title 24, Part) Adoption of 2025 Building Codes 2 October 21, 2025 All of these codes replace the 2022 versions previously adopted by the Town, with the exception of the California Wildland-Urban Interface Code which is brand new. DISCUSSION Town staff is not proposing any local amendments to the California codes approved by the State. While the San Ramon Valley Fire Protection District adopts local amendments to the California Fire Code through its own ordinance, the timing of the Town’s code adoption does not align with the District’s process this cycle. If necessary, the Town may return at a later date to incorporate those amendments into the Danville Municipal Code. The 2025 California Building Standards Code introduces a new Wildland-Urban Interface (WUI) Code consolidating wildfire safety standards for construction and landscaping in high-risk fire zones to improve community resilience and fire protection. This new WUI Code will be codified in Chapter 10-20 of the Danville Municipal Code and applies to new construction and significant remodels in designated Fire Hazard Severity Zones. It ensures compliance with updated state-mandated ignition-resistant construction, defensible space, and vegetation management requirements.
