Hazard is not the same as your insurance risk
A Fire Hazard Severity Zone measures long-term physical wildfire hazard - vegetation, terrain, weather, and fire history - to guide land-use planning, building codes, and defensible-space rules. It is not an insurer's property-level underwriting score or catastrophe model. The California Department of Insurance has stated that CAL FIRE's maps do not by themselves determine insurance rates or availability, so a zone designation is one input among many, not the decision.
When carriers price a home and decide whether to write it, they may evaluate factors such as:
- Roof type and age, and overall construction
- Surrounding vegetation and defensible space
- Slope, terrain, and road access
- Distance from a fire station and available water supply
- Replacement cost and the home's loss history
- Their own proprietary wildfire catastrophe models

Contra Costa County FHSZ FAQ
Is Contra Costa County in a Fire Hazard Severity Zone?
Yes. CAL FIRE maps parts of Contra Costa County as High or Very High Fire Hazard Severity Zones, especially in the wildland-urban interface.
Does a Fire Hazard Severity Zone set my insurance rate in Contra Costa County?
No. A CAL FIRE zone classifies long-term physical wildfire hazard for planning, building, and mitigation. It is not an insurer's underwriting score or catastrophe model, and the California Department of Insurance has stated the maps do not by themselves determine insurance rates or availability. Carriers price each property on its own characteristics.
Can I still get homeowners insurance in Contra Costa County?
Yes. As an independent broker we shop admitted carriers writing Contra Costa County, then surplus lines wildfire markets and the California FAIR Plan paired with a difference-in-conditions wrap when a home is hard to place in the standard market.
Does the California FAIR Plan cover Contra Costa County?
Yes. The California FAIR Plan is available statewide, including Contra Costa County, as a last-resort option for fire coverage when the standard market declines. It is typically paired with a difference-in-conditions policy for the theft, liability, and water damage the FAIR Plan does not include.
What is a Very High Fire Hazard Severity Zone (VHFHSZ)?
A Very High Fire Hazard Severity Zone is CAL FIRE's highest wildfire-hazard classification, based on factors like vegetation, terrain, and fire history. The zone triggers stricter building codes and defensible-space and home-hardening rules; it is a hazard measure, not an insurer's decision, though insurers may weigh a property's wildfire exposure among many underwriting factors.
