CAL FIRE to Release 2025 Fire Hazard Severity Maps

SONOMA COUNTY, CA – CAL FIRE has notified local government fire and planning departments about the potential release of the 2025 Local Responsibility Area (LRA) Fire Hazard Severity Maps. The maps were released on February 24, 2025.

Sonoma County adopted the Sonoma County Fire Safety Ordinance #6396 in 2022, which references development regulations in both the State Responsibility Area (SRA) and LRA Very High Fire Hazard Severity Zones (VHFSZ). CAL FIRE, in coordination with the Office of the State Fire Marshal, is mandated under Title 14 of the Natural Resources Code to periodically update these maps and severity zones. As part of this process, CAL FIRE is required to notify local governments before releasing updated severity zone maps for both the SRA and LRA.

Local governments must adopt these maps when changes affect areas designated as LRA VHFSZ. Under an agreement with CAL FIRE, Sonoma County serves as the inspection authority and enforces fire safety requirements outlined in Sections 13-21 of the county code and Title 14 of the Natural Resources Code. The Fire Safety Ordinance acknowledges these minimum fire safety standards for the LRA and the county will assist with public outreach and development standards related to LRA VHFSZ areas.

Adoption and Implementation

According to the county code, the updated maps will automatically become official 120 days after their release by CAL FIRE. Per the Fire Safety Ordinance and Title 14 of the Natural Resources Code, the updated regulations will apply to unincorporated areas of Sonoma County within the designated VHFSZ, regardless of local fire jurisdiction.
