Boise, ID Outdoor Cooking: Smoker Rules (2026)

Boise City Code does not contain a smoker-specific ordinance. Backyard pellet grills, offset smokers, and wood-fired pizza ovens at single-family or duplex homes are treated as ordinary residential cooking and are not regulated under normal conditions. At multi-unit buildings (3 or more dwelling units), IFC §308.1.4 — adopted via Boise City Code Title 9 — extends to smokers because pellet grills, offset pits, and wood-fired ovens are 'open-flame' or solid-fuel cooking devices and are prohibited on combustible balconies or within 10 feet of combustible construction. Wildfire season restrictions are a significant Boise-specific consideration: Stage 1 fire restrictions typically prohibit open campfires while allowing pressurized propane and charcoal/wood smokers in approved containers; Stage 2 restrictions often prohibit all solid-fuel cooking including wood-fired smokers and pellet grills even at residences, with exceptions only for pressurized gas appliances with shut-off valves. The Boise Fire Department, Idaho Department of Lands, BLM, and US Forest Service coordinate these restrictions. Smoke nuisance: excessive smoke crossing property lines may be addressed under Boise City Code Title 6 (nuisance provisions) with enforcement by Code Enforcement. Idaho DEQ regulates outdoor air quality under IDAPA 58.01.01 but residential cookers are generally exempt; DEQ's Air Quality Index advisories during summer (wildfire smoke), winter (Treasure Valley inversion), and burn restrictions for woodstoves can also affect backyard smoker use. Burn ban days during temperature inversions in winter can restrict solid-fuel use. Foothills Hillside Development Overlay properties face heightened scrutiny due to wildland-urban interface fire risk.
