What are Fire Hazard Severity Zones?

State law requires the California Office of the State Fire Marshal (SFM) to classify lands within State Responsibility Areas into Fire Hazard Severity Zones and transmit maps of those zones to cities with jurisdictions over the zones (Local Responsibility Areas). The SFM is to identify areas in the state as Moderate, High, and Very High Fire Hazard Severity Zones consistent with statewide criteria and based on the severity of fire hazard that is expected to prevail in those areas.

State law also requires that cities designate a Very High Fire Hazard Severity Zone through the adoption of a local map within 120 days of receiving maps of the Fire Hazard Severity Zones from the SFM. To see precise boundaries of streets and areas within Fire Hazard Severity Zones, as of April 1, 2024, please visit the CalFire Fire Hazard Severity Zone viewer.

How might Fire Hazard Severity Zones affect property owners?

State law through SB 63 requires that the State Fire Marshal and the California Department of Housing and Community Development extend certain building standards and Wildland Urban Interface (WUI) regulations for Very High Fire Hazard Severity Zones. Such regulations require compliance with defensible space standards and WUI regulations.
