2025 Fire Hazard Severity Zone Adoption
CAL-Fire's Office of the State Fire Marshal (OSFM) has released updated Fire Hazard Severity Zone (FHSZ) maps for 2025. These updates reflect modern wildfire risks and directly impact our Local Responsibility Areas (LRAs).
The Fire Hazard Severity Zone maps are created and regulated solely by CAL-Fire's Office of the State Fire Marshal (OSFM). While the City of Hemet / Hemet Fire Department / Department of Life Safety did not develop these maps and lacks the authority to alter or regulate them, we provide this information to ensure that property owners are aware of the proposed upcoming changes to the maps and regulations.
Key changes include:
• Fire Hazard Severity Zone boundaries have been updated.
• 100 feet of defensible space is required in Very High FHSZ.
• New construction must meet Wildland-Urban Interface (WUI) building codes.
• Property sellers must disclose FHSZ status.
