2025 Fire Hazard Severity Zone's

The recent updates to Fire Hazard Severity Zones (FHSZ) in California provide a more accurate assessment of wildfire risks based on modern climate data and fire modeling. These updates affect both State Responsibility Areas (SRA) and Local Responsibility Areas (LRA), influencing fire prevention measures, building codes, and real estate disclosures.

Adoption of these newest maps for the LRA is required by Legislative Assembly Bill 211 (AB211). Monterey County Regional Fire District (MCRFD) has 120 days to adopt these map updates. MCRFD received these maps on March 10, 2025. The updated regulations will apply to those areas located within the District boundaries. The District has no influence over downgrading hazard levels, we can only increase them if justified

Key Takeaways:

FHSZ Classification: Properties are categorized as Moderate, High, or Very High Fire Hazard Severity Zones based on terrain, vegetation, fire history, and climate conditions.
Fire Hazard vs. Risk: The maps indicate hazard potential, not immediate risk, and do not account for mitigation efforts like defensible space or fire-resistant construction.
Impact on Property Owners:
- Homeowners in Very High FHSZ must comply with stringent defensible space and home hardening requirements.
- 100-foot defensible space clearance is mandatory around structures in these zones.
- New construction and renovations in designated zones must adhere to Wildland-Urban Interface (WUI) building codes.
- Property sellers must disclose FHSZ designations during real estate transactions.

Legislative Updates:

Senate Bill 63 (2021) now requires FHSZ classifications to include Moderate and High zones in addition to Very High, expanding fire hazard oversight.
Assembly Bill 337 (1992) originally mandated the identification of Very High Fire Hazard Severity Zones following devastating wildfires.

Mapping & Compliance:

The State Fire Marshal is responsible for updating FHSZ maps, which are used to enforce fire safety standards across the state.
Residents can check their property's FHSZ status online at osfm.fire.ca.gov/FHSZ.
Local jurisdictions are required to review and adopt the updated maps, ensuring communities are better prepared for wildfire threats.
