Fire Hazard Severity Zone Map

Government Code section 51178 requires the State Fire Marshal to identify areas in the state as moderate, high, and very high fire hazard severity zones based on consistent statewide criteria and based on the severity of fire hazard that is expected to prevail in those areas.

Moderate, high, and very high fire hazard severity zones shall be based on fuel loading, slope, fire weather, and other relevant factors including areas where winds have been identified by the Office of the State Fire Marshal as a major cause of wildfire spread. 

The latest Fire Hazard Severity Zone Map for Calabasas was published by CALFIRE on March 24, 2025.

Why the Local Responsibility Area Fire Hazard Severity Zone maps matter:

 The LRA FHSZ maps are used to inform land-use decisions, building standards, and wildfire mitigation practices.

Properties identified within high or very high zones may be subject to California Building Code Chapter 7A and defensible space requirements pursuant to Public Resources Code 4291.
