Upland, CA Fire Regulations: Wildfire Zones (2026)

Upland is a foothill city at the base of the San Gabriel Mountains, and its northern edge carries serious wildfire exposure. According to CAL FIRE's Fire Hazard Severity Zone data (the official statewide map service), the northern foothill portion of Upland near the San Antonio Heights edge is classified Very High Fire Hazard Severity Zone in both the State Responsibility Area and the Local Responsibility Area, while the central, developed part of the city returns no fire-hazard-zone designation. Fire protection is provided by the San Bernardino County Fire Protection District (SBCFPD), and on June 10, 2025 the San Bernardino County Board of Supervisors, acting as the SBCFPD governing body, adopted Ordinance No. 4489 designating updated Fire Hazard Severity Zones (moderate, high, very high) in the district's Local Responsibility Areas, aligning with state law (SB 63). Residents can look up their own parcel using CAL FIRE's Fire Hazard Severity Zone viewer and the SBCFPD map page. For parcels in High or Very High zones, California Public Resources Code 4291 and Government Code 51182 require maintaining up to 100 feet of defensible space around structures (not beyond the property line), with grass cut to about 4 inches and dead vegetation removed. Upland's own Weed Abatement Program reinforces this with a 30-foot defensible-space standard citywide. Buildings in these zones are also subject to wildland-urban interface construction standards under the state fire code.
