Westminster, CA Fire Regulations: Wildfire Zones (2026)

Wildfire hazard mapping in California is handled by CAL FIRE's Office of the State Fire Marshal, which classifies land into Moderate, High, and Very High Fire Hazard Severity Zones based on fuels, terrain, fire history, and weather. In Orange County, those zones concentrate in the foothills and canyons—areas such as the Cleveland National Forest fringe and hillside communities—and CAL FIRE released updated Local Responsibility Area maps for the county in 2025. Westminster, by contrast, sits on the flat coastal plain of northwestern Orange County and is essentially fully developed with residential, commercial, and light-industrial uses and no adjacent wildland fuel. As a result, it is not designated as a Very High Fire Hazard Severity Zone, and the special building hardening and 100-foot defensible-space requirements that attach to those zones (under the California Fire Code and Public Resources Code section 4291) are not triggered for typical Westminster properties. The Orange County Fire Authority provides fire protection to the city and would be the authority for any future zone determinations. Property owners should still control dead and overgrown vegetation under the city's nuisance code (WMC Chapter 8.20) and maintain general fire safety, but Westminster's structural fire risk centers on building and urban hazards rather than wildfire. Residents can confirm a specific parcel's status using OCFA and CAL FIRE hazard-zone viewers.
