San Diego County's Fire Hazard Severity Zones Updated: What Homeowners Need to Know
In March 2025, the California Office of the State Fire Marshal released updated Fire Hazard Severity Zone (FHSZ) maps for San Diego County—the first major revision in over a decade. These maps, which assess wildfire hazard based on factors like vegetation, slope, and fire history, are crucial tools for homeowners, buyers, and sellers alike.
🔥 Key Changes in San Diego County
Significant Expansion of High-Risk Areas: The acreage classified as "Very High" fire hazard increased by 26%
Newly Affected Cities: Imperial Beach, La Mesa, and Lemon Grove now have areas designated as "Very High" hazard zones for the first time.
🏡 Implications for Homeowners
Insurance Considerations: While insurers are not mandated to use these maps for underwriting, properties in high-risk zones may face increased premiums or coverage challenges.
Building and Maintenance Requirements: Homes in these zones may be subject to stricter building codes, including the creation of "Zone Zero"—a 5-foot ember-resistant area around structures.
Property Value and Marketability: The designation can influence property values and may be a factor for potential buyers concerned about wildfire risks.
