Hazard is not the same as your insurance risk
A Fire Hazard Severity Zone measures long-term physical wildfire hazard to guide building codes and defensible-space rules. It is not an insurer's underwriting score, and the California Department of Insurance has stated that CAL FIRE's maps do not by themselves determine insurance rates or availability. Carriers weigh your roof, your defensible space, your access and water supply, and their own catastrophe models - so a zone designation and a carrier's decision can and do diverge.
We explain that gap in full, including what the 2025 statewide map update changed and why most homes destroyed in the Eaton Fire sat outside the mapped very-high zone, on our California Fire Hazard Severity Zone guide. You can look up any San Joaquin County address on the official CAL FIRE zone viewer.

These are incidents CAL FIRE responded to or monitored, not every ignition in California, so treat the count as a measure of significant fire activity rather than a complete tally. Acreage attributed to the county excludes multi-county complexes, because CAL FIRE reports acres per incident rather than per county.
