Wildfire Zones: Carson vs Lakewood
How do wildfire zones rules compare between Carson, CA and Lakewood, CA?
Carson has fewer restrictions than Lakewood.
Carson, CA
Los Angeles County
Carson lies in Los Angeles County's urban/industrial core and is largely outside CAL FIRE-designated Very High Fire Hazard Severity Zones. There is no Local Responsibility Area VHFHSZ mapped over the developed portion of Carson, so WUI building standards (Cal. Building Code Chapter 7A) generally do not apply — but PRC §4291 defensible space is mandatory on any parcel that does fall in a designated zone.

Carson FAQ
Is Carson in a wildfire hazard zone?
The developed core of Carson is not mapped as a Very High Fire Hazard Severity Zone by CAL FIRE / Office of the State Fire Marshal. Carson's fire risk is dominated by industrial and refinery exposures rather than wildland fire.
Do I need Chapter 7A ignition-resistant materials when I build?
Generally no — California Building Code Chapter 7A applies only to structures in a designated FHSZ. Check the OSFM Fire Hazard Severity Zone viewer for your specific parcel before assuming exemption.
Where can I check my parcel's fire hazard zone?
Use the California Office of the State Fire Marshal Fire Hazard Severity Zone viewer at osfm.fire.ca.gov — search by address. LACoFD also maintains local hazard maps.
Lakewood FAQ
How much defensible space do I need?
Typically 30 feet of lean/clean zone and 100 feet of reduced fuel zone around structures in Lakewood wildfire areas.
Is my property in a wildfire zone?
Check with Lakewood fire department or your state wildfire hazard map. Real estate disclosures must include wildfire zone status.
