Very High Fire Hazard Severity Zones

New! 2025 Fire Hazard Severity Zone Map Released
The Office of the State Fire Marshal (OSFM) has released the updated 2025 Local Responsibility Area (LRA) Fire Hazard Severity Zone (FHSZ) Map. For detailed information and to view the new map, visit the 2025 LRA FHSZ Map Page.


State law requires that all local jurisdictions identify very high fire hazard severity zones within their areas of responsibility. Inclusion within these zones is based on vegetation density, slope severity and other relevant factors that contribute to fire severity.

Very High Fire Hazard Severity Zone Map

The purpose of this map is to classify lands in accordance with whether a very high fire hazard is present so that public officials are able to identify measures that will retard the rate of fire spread and reduce the intensity of uncontrolled fire through vegetation management and implementation of building standards developed to minimize loss of life, resources and property.
