Idaho Falls, ID Fire Regulations: Wildfire Zones (2026)

Idaho Falls does not designate Wildland-Urban Interface (WUI) zones, fire-hazard severity zones, or a defensible-space overlay in its City Code; the City's adopted 2018 International Fire Code (City Code 7-10-1) governs construction and fire-protection generally rather than mapping wildfire zones. The City's terrain on the Snake River Plain is largely flat agricultural and developed land, giving it a lower wildland-fire exposure than Idaho's forested mountain towns - though dry grass and rangeland on the urban fringe and in unincorporated Bonneville County still carry summer fire risk. Wildfire risk is therefore managed through seasonal, jurisdiction-wide tools rather than a permanent zone map: the Bonneville County Commissioners issue county-wide burn bans during periods of high temperature and low humidity (for example, a ban effective July 25 through September 30, 2025) that prohibit all outdoor burning, fireworks and exploding targets to reduce wildfire risk; campfires in approved pits at improved campgrounds and picnic areas are excepted, and the ban applies to private property in unincorporated parts of the county. Statewide, Idaho Code 39-2609(4) makes it unlawful to use fireworks in any area that constitutes a severe fire threat based on current-season vegetative conditions as determined by the county commission or fire authority. The Idaho Department of Lands maintains a Fire Restrictions Finder for current statewide restrictions.
