Corona, CA Fire Regulations: Brush Clearance (2026)

Corona enforces brush and weed abatement under Corona Municipal Code Chapter 8.20 in coordination with Riverside County Fire/CAL FIRE, applying California's statewide 100-foot defensible space rule from Public Resources Code §4291 to all parcels within or adjacent to State Responsibility Areas (SRA) and Local Responsibility Area Very High Fire Hazard Severity Zones (LRA-VHFHSZ). Defensible space is divided into Zone 0 (0-5 feet ember-resistant zone added under AB 3074, regulations finalizing 2025), Zone 1 (5-30 feet 'lean, clean and green'), and Zone 2 (30-100 feet reduced fuel zone with grass mowed to 4 inches and limbs trimmed). Hillside Corona neighborhoods including Skyline Drive, the Sierra Del Oro/Coronita corridor, and parcels backing onto Cleveland National Forest receive annual notice-and-inspection cycles each spring before fire season. Notices typically allow 30 days for owner abatement before the city engages a contractor for forced abatement at owner expense plus administrative fees, with costs recorded as a special assessment against the property tax roll if unpaid. Empty lot owners are equally responsible for weed abatement to a 6-inch height over the entire parcel under MC Chapter 8.20.
