Idaho Falls, ID Fire Regulations: Brush Clearance (2026)

Idaho Falls sits on the relatively flat Snake River Plain, and the City does not publish a formal vegetation-management / defensible-space clearance ordinance comparable to wildland-urban-interface cities in higher-fire-risk states. Brush, weed and irrigation-ditch clearing by burning is treated as 'irrigation/weed control' fire by the Idaho Falls Fire Department and is only permissible with a Fire Code Operational Permit from Fire Prevention, where other means are impractical and the fire poses little to no nuisance. Statewide fire law addresses dry-vegetation risk indirectly: Idaho Code 39-2609(4) makes it unlawful to use fireworks in any area that constitutes a severe fire threat based on the vegetative conditions during the current fire season, as determined by the county commission or authority having jurisdiction, when notice is given. During hot, dry summers the Bonneville County Commissioners issue county-wide burn bans (for example, effective July 25 through September 30, 2025) that ban all outdoor burning, fireworks and exploding targets to reduce wildfire risk and protect lives and property; campfires in approved pits at improved campgrounds or picnic areas are excepted. Property owners should keep dry grass and weeds cleared and avoid parking vehicles on dry grass as the county recommends.
