Solano County, CA Fire Regulations: Brush Clearance (2026)

Chapter 12.5 of the Solano County Code authorizes the county officer charged with fire protection — or the local fire protection district (CAL FIRE LNU, Vacaville Fire Protection District, Suisun Fire Protection District, Cordelia Fire Protection District, Montezuma Fire Protection District, or Rural North Solano FPD depending on location) — to order the clearing of flammable vegetation as a nuisance. Under California Public Resources Code §4291, every person who owns, leases, or controls land covered with flammable material in the SRA must maintain a defensible space of 100 feet around every building or structure: Zone 1 (0–30 feet) is the lean-clean-and-green zone with all dead vegetation removed and trees pruned 10 feet from chimneys; Zone 2 (30–100 feet) requires reduced fuels with horizontal and vertical spacing between plants. Zone 0 (0–5 feet) is a state-required ember-resistant zone with no combustible materials. Government Code §51182 imposes the equivalent 100-foot standard in LRA Very High Fire Hazard Severity Zones; on February 24, 2025, the State Fire Marshal released updated LRA FHSZ maps for Solano County, which the County Board of Supervisors adopted to begin enforcement in July 2025. Common violations include dry grass over 4 inches near structures, accumulated dead brush, woodpiles within 30 feet of a home, and tree branches overhanging roofs.
