Portions of Fullerton in the northern hills near the Puente Hills and West Coyote Hills are designated as Very High Fire Hazard Severity Zones (VHFHSZ) by CAL FIRE. Properties in these zones face additional building and landscaping requirements.
CAL FIRE designates portions of northern Fullerton, particularly areas near the West Coyote Hills and the Puente Hills, as Very High Fire Hazard Severity Zones. Properties in these zones must comply with California Building Code Chapter 7A for ignition-resistant construction, including fire-rated roofing, exterior wall materials, and ember-resistant vents. The Fullerton Fire Department enforces defensible space requirements per California PRC Section 4291, requiring 100 feet of brush clearance around structures. New construction and major remodels in VHFHSZ areas require fire-resistant landscaping plans and may need fire sprinkler systems. The Fire Department conducts annual inspections of properties in fire hazard zones. Fullerton participates in the Orange County Fire Authority mutual aid system for wildfire response.
Failure to maintain defensible space may result in citations, fines up to $500 per violation, and potential criminal liability if a fire results. Non-compliant construction may receive stop-work orders.
