2025 Fire Hazard Severity Zones: What You Need to Know
CAL FIRE has released updated 2025 Fire Hazard Severity Zone (FHSZ) maps, bringing a more accurate picture of wildfire risk across California. These maps are based on improved science, fire history, vegetation, and climate data. You can view the maps here: FHSZ Viewer.

Top 3 Things to Know:
1. More Detailed and Accurate Maps
The new maps show expanded high and very high hazard areas, especially in rural and wildland-urban interface zones. This reflects updated risk modeling.
2. Impact on Homeowners and Insurance
If your property is now in a higher risk zone, you may face insurance changes or requirements for defensible space and home hardening. It’s important to stay informed.
3. Public Outreach Matters
Counties like San Luis Obispo are stepping up outreach to help residents understand these changes and how to prepare. Local input is important in this process.
