Summary
Antioch's municipal code does not set a specific lawn-grass height limit, but Antioch MC § 5-1.202 declares 'overgrown, dead or decayed trees, weeds or other vegetation' that poses a public-safety risk or visual blight a prohibited nuisance. The Contra Costa County Fire Protection District's annual Weed Abatement Program, which covers Antioch, enforces minimum vegetation-clearance standards each spring to limit wildfire spread.
Premises on which overgrown, dead or decayed trees, weeds or other vegetation pose a risk of harm to the public, or constitute visual blight or reduce the aesthetic appearance of the neighborhood, or are offensive to the senses, or are detrimental to the use and enjoyment of nearby properties.
Full Breakdown
, 'grass over six inches'). 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.
Violations & Fines
Code Enforcement may issue a Notice to Abate giving the owner a fixed period (typically 30 days, shorter in fire season) to clear vegetation. Non-compliance authorizes the City or CCCFPD to enter the property, perform abatement, and bill the cost back to the owner, which can become a special tax lien on the parcel. Continuing nuisances may be charged as infractions or misdemeanors under AMC Title 1.
