Eastern and northern Tucson neighborhoods adjacent to Saguaro National Park, Coronado National Forest, and Tucson Mountain Park fall within mapped wildland-urban interface zones. Properties in these zones face stricter building code requirements including Class A fire-resistant roofing, ember-resistant vents, and defensible space maintenance.
Arizona Forestry and Tucson Fire map WUI severity zones based on topography, fuel type, and historic fire occurrence. New construction and substantial remodels in severe zones must meet IWUIC 2021 construction standards adopted by the city. Features include 1-hour-rated exterior walls within 10 feet of property line, non-combustible decking, and ember-resistant under-eave vents. The 2003 Aspen Fire and 2020 Bighorn Fire on Mount Lemmon prompted tighter rules. Homeowners can request a free defensible space inspection from Tucson Fire.
Building permits are withheld until WUI compliance is verified. Existing properties with defensible space deficiencies face abatement orders. Post-fire investigations may find owners liable for spread from their property if they failed to maintain required clearance.
