Vacaville, CA Landscaping Rules: Weed Ordinances (2026)

Vacaville's primary weed-abatement authority is VMC Chapter 8.04 (Abatement of Weeds and Rubbish). The chapter declares all weeds and rubbish constituting a fire or sanitation hazard a public nuisance, and authorizes the City to inspect properties on or about June 1 each year, issue notice to clear, and abate non-compliant properties at the owner's expense. Costs are recovered as administrative fines and ultimately as special assessment liens on the property tax bill under the procedures of California Government Code Section 39561 et seq. The Vacaville City Council periodically takes action to place liens on chronically non-compliant properties. Separate from city-level weed abatement, the Solano County Agricultural Commissioner administers the Solano Weed Management Area program targeting state-listed noxious weeds - yellow starthistle (Centaurea solstitialis), perennial pepperweed/whitetop (Lepidium latifolium), medusahead (Elymus caput-medusae), and Italian thistle - under California Food & Agricultural Code Sections 5001-5026. Defensible-space and fire-hazard clearance under California Public Resources Code Section 4291 overlay these rules for parcels in or near State Responsibility Areas, including portions of the Vaca Hills and Lagoon Valley. Code Enforcement is reachable at (707) 449-5693 or CodeEnforcement@CityofVacaville.com.
