Fremont requires lawns and weeds kept below 6 inches citywide, and 4 inches in east foothill VHFHSZ defensible space zones. Overgrown lots are tagged for abatement each spring.
Fremont Municipal Code weed abatement rules require property owners to keep grass, weeds, and rank vegetation cut to a reasonable height, generally interpreted at 6 inches on flatland parcels. In the east foothill Very High Fire Hazard Severity Zone (Mission Peak, Weibel, Niles Canyon, Mission San Jose foothills), PRC 4291 defensible space requires grass and non-native annual grasses to be maintained at 4 inches or less within 100 feet of structures. The Fremont Fire Department opens the weed abatement season in April, posts notice, and inspects properties. Non-compliant owners receive a correction notice with 30 days to cure. Failure to comply triggers contractor abatement billed to the owner through an Alameda County property tax lien. Vacant lots, creek edges, and hillside parcels draw the most enforcement attention.
