Wildfire Zones: Lodi vs Stockton
How do wildfire zones rules compare between Lodi, CA and Stockton, CA?
Lodi and Stockton have similar restriction levels.
Lodi, CA
San Joaquin County
Lodi is a Central Valley flatland city (elevation about 52 feet) located in the Local Responsibility Area (LRA) and is NOT mapped by the California State Fire Marshal as a Moderate, High, or Very High Fire Hazard Severity Zone under California Government Code Sections 51178-51179 (LRA) or Public Resources Code 4202 (SRA). As a result, the 100-foot defensible-space requirements of PRC 4291 and the Wildland-Urban Interface (WUI) building standards of California Building Code Chapter 7A do not apply citywide. Lodi remains subject to the California Fire Code adopted at LMC Chapter 15.20.

San Joaquin County
Stockton sits in Local Responsibility Area (LRA) on the San Joaquin Valley floor and is NOT classified as a Very High Fire Hazard Severity Zone (VHFHSZ) by CAL FIRE on the 2024 LRA maps. WUI building standards (Chapter 7A) and Public Resources Code 4291 defensible space requirements therefore do not apply to most Stockton parcels.

Lodi FAQ
Is Lodi in a wildfire hazard zone?
No. The California State Fire Marshal's Local Responsibility Area Fire Hazard Severity Zone maps released in 2025 do not designate Lodi as a Moderate, High, or Very High Fire Hazard Severity Zone. Lodi sits on the floor of the San Joaquin Valley with flat, irrigated terrain and limited wildland fuel.
Do I have to clear 100 feet around my house in Lodi?
No. The 100-foot defensible-space rule in Public Resources Code 4291 applies in State Responsibility Areas and Very High Fire Hazard Severity Zones. Lodi is not in either, so PRC 4291 does not apply citywide. You still must comply with the Lodi 12-inch grass standard and the California Fire Code's general combustible-waste rules.
Do new Lodi homes need ignition-resistant WUI construction?
No, not citywide. California Building Code Chapter 7A (ignition-resistant construction in WUI fire areas) is triggered in mapped FHSZ areas. Because Lodi is not designated FHSZ, Chapter 7A is not required for new construction unless local planning conditions specifically apply it.
Stockton FAQ
Do I need ignition-resistant siding or vents for a new home in Stockton?
California Building Code Chapter 7A WUI standards apply only in VHFHSZ areas and SRA. Stockton is not in a VHFHSZ on the 2024 CAL FIRE LRA maps, so Chapter 7A construction standards are not required citywide. Verify a specific parcel via the CAL FIRE FHSZ viewer or the San Joaquin County GIS map.
Will my insurance company treat Stockton as a wildfire-risk area?
Insurance carriers use their own risk models (e.g., Verisk, CoreLogic), which may classify some Stockton ZIP codes as elevated risk even when CAL FIRE does not. The official CAL FIRE FHSZ map is the legal trigger for code requirements, but insurer pricing decisions are separate.
