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.
