Berkeley FAQ
How do I check if my home is in the VHFHSZ?
Use the CAL FIRE FHSZ Viewer online or Berkeley's parcel map. Most homes east of the Hayward Fault (roughly above Shattuck elevation) fall inside the VHFHSZ.
Do I need to retrofit my existing home to WUI code?
Only new construction and substantial remodels trigger Chapter 7A compliance. However, voluntary home hardening is strongly encouraged and may qualify for insurance discounts under the Safer from Wildfires framework.
Hayward FAQ
Is all of Hayward in the VHFHSZ?
No. Only the eastern hillside neighborhoods. Flatland Hayward west of the hills is not in the VHFHSZ.
Does AB 38 apply to my sale?
Yes if the home is in the VHFHSZ; sellers must disclose and may need to demonstrate defensible space compliance.
