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.
Sunol FAQ
When do inspections occur?
The Alameda County Fire Department and CAL FIRE typically inspect from May through October, with peak focus in June and July before peak fire season.
What happens if I fail inspection?
You receive a notice to correct with a deadline; failure to correct results in fines and county abatement where contractors perform the work and bill the property owner.
