Full Breakdown

Unincorporated LA County requires weed and vegetation maintenance primarily through fire hazard abatement and nuisance ordinances. In fire hazard zones, the LA County Fire Department mandates all weeds and grass be cut to 3 inches or less within 200 feet of structures (defensible space). Outside fire zones, the LA County Agricultural Commissioner operates a weed abatement program targeting vacant lots and unimproved parcels. Property owners receive annual notices to clear weeds. The county can perform the abatement and bill the property owner if they fail to comply.

Violations & Fines

Agricultural Commissioner weed abatement: property owner billed for clearing costs plus 35% administrative fee. Liens placed for non-payment. Nuisance abatement for overgrown lots: fines of $100-$500 per day after notice period.
