Fremont FAQ
How do I check if my Fremont home is in a VHFHSZ?
Use the CAL FIRE Fire Hazard Severity Zone viewer at osfm.fire.ca.gov or contact Fremont Fire Prevention at 510-494-4200 with your address for a written determination.
Does VHFHSZ affect my insurance?
Yes. Many carriers non-renew VHFHSZ policies. The California FAIR Plan is the insurer of last resort. Completing home hardening and defensible space can qualify you for the Safer from Wildfires insurance discount.
Oakland FAQ
How do I find out if my Oakland home is in the VHFHSZ?
Check the City's online Fire Zone GIS map or enter your address on the CAL FIRE FHSZ viewer. If your parcel is in the zone, defensible space, Chapter 7A, and AB 38 disclosure requirements apply.
What is AB 38 disclosure?
AB 38 (effective 2021) requires sellers of homes in high or very high fire hazard zones to provide documentation of defensible space compliance and, for homes built before 2010, disclose specified ignition-resistance retrofit items in the Natural Hazard Disclosure Statement.
