Garden Grove is a flat, fully urbanized city in central Orange County and First Street rates citywide wildfire risk as Very Low (about 4% of buildings at any risk). The City has not historically been mapped as containing CAL FIRE High or Very High Fire Hazard Severity Zone (FHSZ) area, so AB 38 disclosure and statewide defensible-space rules generally do not apply. Verify your parcel against the 2025 LRA FHSZ map before relying on this.
California's Fire Hazard Severity Zone (FHSZ) program, run by CAL FIRE and the Office of the State Fire Marshal under Public Resources Code 4201-4204 and Government Code 51175-51189, maps Moderate, High, and Very High zones across both State Responsibility Areas (SRA) and Local Responsibility Areas (LRA). Garden Grove sits at the flat coastal-plain core of Orange County with no canyons, foothills, or wildland-urban interface, and First Street's wildfire model rates the City as Very Low overall, with only about 4% of buildings at any modeled wildfire exposure. Unlike eastern Orange County cities (Anaheim Hills, Yorba Linda, Orange, Mission Viejo, Lake Forest, Laguna Beach, Laguna Niguel, San Clemente) that contain mapped Very High FHSZ in their hillside portions, Garden Grove has not historically been listed on the OC Public Works Very High FHSZ in LRA roster. CAL FIRE issued recommended 2025 LRA FHSZ maps for Southern California on March 24, 2025, and each city must adopt the maps; confirm any change for a specific parcel using the CAL FIRE FHSZ Viewer before assuming a property is exempt. Where no FHSZ designation exists, AB 38 (Civil Code 1102.19, Government Code 51182, 51189) defensible-space disclosure at point of sale and the PRC 4291 100-foot defensible-space rule do not attach. Garden Grove still adopts the 2022 California Fire Code with local amendments at GGMC Chapter 8.18 and the Orange County Fire Authority enforces weed abatement, vegetation management on vacant lots, and fire-lane standards citywide. Confirm your parcel's FHSZ status with OCFA at (714) 573-6000 or with the Garden Grove Fire Marshal before buying or building.
If a parcel is later mapped into a High or Very High FHSZ, owners become subject to PRC 4291 defensible-space requirements, Chapter 7A wildland-urban-interface building standards (CRC R337), and AB 38 seller disclosure at sale; failure to disclose or maintain defensible space can trigger civil penalties, transaction delays, and OCFA enforcement.
