Has this property burned?
Check any California address or coordinate against CAL FIRE’s mapped wildfire perimeters, 1950 to the present. Every fire by name, year and size.
Rural parcels are often missing from the national address database. If yours isn’t found, enter coordinates instead — for example .

Two different answers, both shown. Fire history tells you what has already burned. The Fire Hazard Severity Zone, shown beneath it, is CAL FIRE’s forward-looking rating — fuel, slope and weather — and the one that drives building codes, defensible-space rules and insurance decisions.
A property with no recorded fire can still sit in a Very High zone, and a property that burned decades ago may not. The zones come from the Office of the State Fire Marshal’s 2024–25 maps for state and local responsibility areas.
Nothing here is an insurance determination, an appraisal, or a substitute for professional due diligence.
How it works
Your address is converted to a coordinate, then tested against every CAL FIRE mapped perimeter to see whether that exact point falls inside one. This is the same check Trelys runs on every parcel California counties auction for unpaid taxes.
The address database behind the lookup is maintained by the US Census Bureau and has real gaps in rural areas — and it will occasionally match a similarly-spelled street rather than yours. That is why the matched address is always shown back to you, and why coordinates are accepted directly.
