Is your home in a Zone 0 area? Check your address

Queries CAL FIRE's official hazard layers directly·Your address never touches our servers

Enter a California street address. Your browser sends it straight to an OpenStreetMap geocoder to get coordinates, then queries CAL FIRE's official Fire Hazard Severity Zone map service, the same data behind the state's own viewer. We never see, log, or store the address.

Street address, city, CA

How to read your result

Official designation	Under the adopted state Zone 0 rule
State Responsibility Area (SRA), any hazard class	Covered, once the rule takes effect (Public Resources Code §4291)
Local Responsibility Area (LRA), Very High	Covered, once the rule takes effect (Gov. Code §51182)
LRA, High or Moderate	Not covered by the state rule, though local rules may apply
No mapped zone	Not covered by the state rule; local agencies can still designate area

Details on the two-statute split: Does Zone 0 apply to your home? Whatever the map says, the insurance credit for noncombustible fencing applies statewide to insurers that price wildfire risk.

Accuracy notes, honestly stated: this checks a point at your address against CAL FIRE's published layers (SRA effective April 2024; LRA zones per the March 2025 state maps). LRA zones take legal effect through local adoption, local agencies may designate more area than the state map shows, and parcels on zone boundaries deserve a closer look. Address lookup is done by OpenStreetMap-based geocoders, so a hard-to-find address may land on the street rather than the parcel. For anything consequential, confirm on the official OSFM FHSZ page and with your local fire agency. Not legal advice. Geocoding © OpenStreetMap contributors.

Frequently asked questions

Where does the data come from?

Geocoding: OpenStreetMap (Nominatim, with Photon as a backup). Hazard designation: CAL FIRE's published Fire Hazard Severity Zone feature service (the "FHSZ for real estate inspections" layer, which combines SRA zones and the 2025 LRA classifications). Both are queried live from your browser.

My result says "no mapped zone" but I got a Zone 0 mailer. Who's right?

Possibly both. The state rule reaches only SRA land and LRA Very High zones, and many mailers are sent far beyond that footprint. But local agencies can designate additional area, so check with your city or fire district too. The myths article covers what mailers get wrong.

Does a covered result mean I have to do something today?

Statewide, no: the Board approved the regulation on August 19, 2026, but it is not in effect yet, and no compliance clock starts until an effective date exists. Once it does take effect, fences are a phased item for existing homes. Locally, six jurisdictions already have requirements in force: the Ventura County Fire Protection District, Laguna Beach, the Moraga-Orinda Fire District, Auburn, Berkeley's hillside zones, and the City of San Diego.
