Solano County, CA Property Maintenance: Weeds & Overgrown Grass (2026)

Weed and dry-grass control in unincorporated Solano County is handled through Chapter 12.5 of the County Code, Abatement of Fire Hazards, rather than a generic lawn-height ordinance. Under Section 12.5-20, the county officer charged with fire protection in the unincorporated area, or that officer's designated agent, may call the existence of flammable material that endangers public safety to the attention of the applicable fire protection district, and the fire protection district 'may clear or order the clearing of land, or remove or order the removal of dry grass, stubble, brush, rubbish, litter, or other flammable material.' Section 12.5-21 provides the enforcement teeth: if an owner, occupant, or person in charge fails to comply with a clearing requirement, the county or the fire protection district may do the work, and the reasonable cost becomes a lien against the property when a notice of lien is recorded with the County Assessor/Recorder. The cost is also a personal charge against the owner and can be added to the next year's tax bill or recovered by an action at law. Because Solano County contains multiple fire protection districts, the specific defensible-space distances, deadlines, and inspection schedules are set by the responsible district, not by a countywide height number. The County Code itself does not state a maximum permitted grass or weed height, so any specific clearance figure should be confirmed with the local fire protection district.
