Rialto adopted the State Fire Marshal's updated 2025 fire hazard severity zone maps, which place parts of the city in Moderate, High, or Very High zones. Very High zone properties must maintain 100 feet of defensible space and meet home-hardening and disclosure rules.
On March 24, 2025, the Office of the State Fire Marshal released updated Fire Hazard Severity Zone (FHSZ) maps, and under Government Code section 51179(b)(3) local agencies like Rialto may not decrease the zone levels OSFM recommends; state law (AB 211, 2022) requires adoption within 120 days. The city's FHSZ page explains that properties in a Very High FHSZ must maintain 100 feet of defensible space around structures, comply with home-hardening and wildland-urban interface (WUI) building codes, and disclose the designation when selling; High zone properties face home-hardening and WUI construction requirements for new construction. Rialto's fire code amendments back this up locally: Ordinance No. 1706 adds CFC section 304.5 requiring owners of buildings in or adjoining hazardous fire areas (the FRAP-designated Local Responsibility Area Very High FHSZ) to maintain an effective firebreak by clearing combustible vegetation within 100 feet of structures, and amended section 304.1.3 ties vegetation clearance to Public Resources Code sections 4290 and 4291. Residents can look up their parcel on CAL FIRE's FHSZ map viewer or contact the Rialto Fire Department at 131 S Willow Ave.
The fire chief or fire code official may issue notices to correct hazardous vegetation conditions, impose daily penalties under amended CFC section 113.4 (up to $1,000 per day as a misdemeanor), abate the hazard, and place a lien on the property for the abatement cost (Ord. No. 1706, amended CFC secs. 304.1.3, 304.5.1).
