Baldwin Park, CA Fire Regulations: Wildfire Zones (2026)

Fire Hazard Severity Zones are mapped by the California State Fire Marshal under Government Code section 51178, classifying lands as Moderate, High, or Very High based on fuel, slope and fire weather. The official Local Responsibility Area Fire Hazard Severity Zone map for the City of Baldwin Park (dated March 24, 2025, prepared by CAL FIRE / OSFM) shows the entire incorporated city as "Unzoned LRA." The only Moderate and High zones shown on the map lie outside the city, in the San Gabriel River and quarry corridor near Irwindale and El Monte. Baldwin Park is a roughly seven-square-mile, flat, densely developed San Gabriel Valley city with no significant wildland-urban interface, so it carries none of the elevated wildfire designations that drive special requirements in foothill and hillside communities. Practically, this means the California Building Code's Wildland-Urban Interface (Chapter 7A) construction standards and the 100-foot defensible-space requirement of Public Resources Code 4291 are not triggered for ordinary homes in Baldwin Park. Standard fire-safety measures still apply: keep yards clear of accumulated dry weeds and combustible debris, maintain working smoke and CO alarms, and follow the adopted California/LA County Fire Code. Residents who want to verify a specific parcel can consult the City's posted FHSZ map or the State Fire Marshal's online zone viewer.
