Las Vegas, NV Fire Regulations: Wildfire Zones (2026)

Nevada does not maintain a statutory wildfire zone map equivalent to California's Fire Hazard Severity Zones. Wildfire risk in Las Vegas is assessed using federal BLM fire regime condition class data and the USDA Wildfire Risk to Communities dataset. Under these tools, the vast majority of Las Vegas's urban core is rated low or very low risk because it is surrounded by hardscape and irrigated (or xeriscaped) development without continuous wildland fuels. The western edge neighborhoods abutting Red Rock Canyon NCA and the Spring Mountain front (including parts of Summerlin and The Ridges) are rated moderate risk from fine-fuel grass fires, particularly in years when winter rain produces abundant invasive annual grass that cures in late spring. Nevada has no state-mandated defensible space code equivalent to PRC 4291, but Las Vegas's weed-abatement and international fire code adoption effectively requires maintained property. Homeowners in interface neighborhoods should consider voluntary Firewise USA enrollment and ember-resistant vent screens.
