Antioch, CA Landscaping Rules: Grass Height Limits (2026)

Antioch does not codify a specific lawn-height number (e.g., 'grass over six inches'). Instead, the City regulates overgrown turf and weeds through a nuisance framework: Antioch Municipal Code § 5-1.202 lists 'premises on which overgrown, dead or decayed trees, weeds or other vegetation' that pose a public-safety risk, constitute visual blight, or reduce nearby property values as a Specific Nuisance Prohibited. Code Enforcement responds to 'overgrown vegetation creating a hazard' as a common violation category. Each spring the City partners with the Contra Costa County Fire Protection District (CCCFPD) on an annual Weed Abatement Program; for 2026 the City began work on March 30, 2026 with completion by June 30, 2026 to reduce wildfire risk on City-owned open spaces, and the East-County compliance deadline (which covers Antioch and surrounding cities) was May 15, 2026. CCCFPD's Minimum Weed Abatement Standards, adopted under California Health and Safety Code Division 12, Part 5 and Contra Costa County Ordinance 2023-07, require parcel owners to cut weeds, dry grass, tree litter and other flammable materials that could ignite and endanger public safety. Property owners are responsible for keeping vegetation cut before the fire-season deadline; the City and CCCFPD may abate non-compliant parcels and assess the cost as a property lien.
