Fremont FAQ
Do flatland Fremont homes need defensible space?
PRC 4291 technically applies statewide, but enforcement focuses on VHFHSZ east foothill neighborhoods. Flatland homes in Centerville, Irvington, and Warm Springs face general weed abatement rules rather than full 100-foot clearance.
What happens if I miss the deadline?
The Fremont Fire Department will hire a contractor to clear the property and bill you. Unpaid bills become a lien on your parcel through Alameda County, typically with administrative fees of several hundred dollars on top.
Hayward FAQ
How do I know if I am in the VHFHSZ?
Check the CAL FIRE FHSZ Viewer or call Hayward Fire Prevention at (510) 583-4900.
What happens if I do not clear?
The city issues a notice; failure to comply results in forced abatement billed to the property owner via a lien.
