OVERVIEW
Every three years, the State of California repeals, revises, and republishes the California Building
Code Standards Code in its entirety, and in doing so, adopts and publishes amendments to the
California Fire Code. Counties and fire protection districts may adopt the California Fire Code
by reference or establish more restrictive standards if such changes are reasonably necessary
because of local climatic, geological, or topographical conditions.
On March 14, 2023 (1), the County of San Diego (County) enacted the previous version of the
California Fire Code into the County’s Code of Regulatory Ordinances (Consolidated Fire
Code). As part of today’s proposed actions, the Board of Supervisors would repeal the existing
Consolidated Fire Code and reenact the updated Consolidated Fire Code, and the San Diego
County Fire Protection District (SDCFPD) Board of Directors would adopt the updated 2025
California Fire Code with modifications, which shall be enforced as the 2026 San Diego County
Consolidated Fire Code (2026 Consolidated Fire Code) by SDCFPD. In addition, as part of
today’s proposed actions, the SDCFPD Board of Directors would adopt the new 2025 California
Wildland-Urban Interface (WUI) Code with modifications, which shall be enforced as the 2026
San Diego County WUI Code (2026 WUI Code) by SDCFPD. The WUI Code includes chapters
related to the home hardening from the previous building code and defensible space from the
previous fire code.
There are 11 fire districts and one water district that provide fire services within the geographical
area of the county, including the SDCFPD. In addition to the modifications by the SDCFPD, the
2026 Consolidated Fire Code and the 2026 WUI Code contain modifications that other districts
deem necessary because of local conditions. There are 19 changes to the 2026 Consolidated Fire
Code and 22 to the 2026 WUI Code proposed by the fire marshals of the unincorporated fire
districts. The fire code standards in today’s proposed ordinances increase protection of structures
and property against wildfire-related damage and loss through progressive requirements that go
beyond those required by the State. Key changes include increasing the sizes of water tanks that
are used as an alternative to fire hydrants, increasing the size of unhabitable residential structures
that require sprinkler systems, adding home hardening requirements, and adding defensible space
enforcement requirements on one acre or less vacant properties.
The 10 other local fire districts and the one water district have already adopted the 2026
Consolidated Fire Code and the 2026 WUI Code. To take effect within the fire districts, the 2026
Consolidated Fire Code and the 2026 WUI Code must be either ratified, modified, or denied by
the Board of Supervisors. One of today’s actions is for the Board of Supervisors to ratify the
2026 Consolidated Fire Code and the 2026 WUI Code.
Today’s request is for the Board of Directors of the SDCFPD and the Board of Supervisors to
find this project exempt from CEQA and for the Board of Directors of the SDCFPD to consider
