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.
Oakland FAQ
Do I need to clear 100 feet if my lot is smaller than that?
You only need to clear to your property line. You are not required (or allowed) to clear vegetation on neighboring parcels. If a neighbor's vegetation threatens your structure, coordinate with them or contact OFD's Vegetation Management Unit.
Can I keep a wood fence attached to my house in the Hills?
Zone 0 rules under AB 3074 are phasing out combustible materials within 5 feet of structures. Wood fences directly attached to homes are discouraged and may be cited. Replacing the section within 5 feet of the house with non-combustible material is recommended.
What if I don't clear by the deadline?
Oakland will perform forced abatement through a contractor and bill the owner, typically at rates higher than private clearance. Administrative fines and a lien against the property can also be imposed.
