Chino, CA Fire Regulations: Brush Clearance (2026)

Wildland-urban interface (WUI) parcels in Chino fall under California Public Resources Code §4291, which requires 100 feet of defensible space around any structure (or to the property line, whichever is closer). California Board of Forestry & Fire Protection now defines three zones: Zone 0 (Ember-Resistant Zone, 0–5 ft, no combustibles touching the structure — phase-in under AB 3074), Zone 1 (Lean, Clean & Green Zone, 5–30 ft, mowed grass <4 in, spaced shrubs, no dead vegetation), and Zone 2 (Reduce Fuel Zone, 30–100 ft, vertical/horizontal spacing of trees and brush). The Chino Valley Fire District adopted these standards through CVFD Ordinance 2022-01 (effective March 2022) and updated the local Fire Hazard Severity Zone map under Ordinance 2025-01 (effective September 1, 2025) — CAL FIRE's 2024 update designated portions of southern and western Chino as moderate-to-high FHSZ where local defensible-space rules apply, and >7,300 acres of Chino Hills State Park as Very High FHSZ. Citywide weed and rubbish abatement is enforced by Chino Public Works Services under Chino Municipal Code Title 8 (Health and Safety) as a public-nuisance program; the city's Code Compliance Division (909-334-3319) and Public Works (909-334-3266) handle complaints. CVFD's Vegetation Management unit (weeds@chofire.org / 909-902-5285) conducts inspections in late spring through fall.
