Understanding Fire Zones

Fire Hazard Severity Zones

Fire Hazard Severity Zones classify areas based on fire risk from terrain, vegetation, and weather. Designations can change; confirm your property's status with local hazard maps and align materials with local requirements. CAL FIRE dataset notes SRA FHSZ effective Apr 1, 2024 and LRA recommendations from 2007-2011 (source).

Higher-Exposure Areas

Insurance treatment varies by carrier and policy. Fire hardening may help, but discounts or eligibility are not guaranteed. Confirm details with your insurer.

Communities: Examples vary by map updates; check local hazard maps.

HFHSZ

Hillside / Canyon Areas

Communities: Del Mar (backcountry), Encinitas (eastern), Carmel Valley, Rancho Bernardo, Escondido, Valley Center

MODERATE / COASTAL

Moderate & Urban Zones

Lower fire risk, but coastal homes benefit from non-combustible fencing for salt corrosion resistance and long-term durability. Urban areas may have HOA requirements for material types.
