Berkeley FAQ
What if my lot is less than 100 feet from the neighbor?
You must still clear to your property line and coordinate with neighbors. Berkeley Fire can require reciprocal clearance and will cite both parcels if vegetation threatens structures.
Can I keep my mature oak trees?
Yes, native oaks are encouraged, but lower limbs must be pruned to 6 feet above ground (or 1/3 tree height), and no branches may overhang within 10 feet of the chimney or roof.
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.
