Idaho Falls, ID Outdoor Cooking: BBQ & Propane Rules (2026)

Idaho Falls adopts the International Fire Code, 2018 Edition (City Code 7-10-1, Ord. 3252). IFC Section 308 governs open-flame cooking devices. The model code provides that charcoal burners and other open-flame cooking devices shall not be operated on combustible balconies or within 10 feet of combustible construction, and that LP-gas cooking devices with an LP-gas container of more than 2.5 pounds water capacity (anything larger than a small 1-lb camping canister - which includes a standard 20-lb barbecue tank) shall not be located on combustible balconies or within 10 feet of combustible construction. Exceptions apply where the building, balconies and decks are protected by an automatic sprinkler system, and for one- and two-family dwellings (single-family homes), where backyard grilling is generally allowed away from the structure. These restrictions chiefly affect apartments, condos and townhomes. Idaho Falls also restricts bulk LP-gas storage to industrial zones I&M-1 and I&M-2 (City Code 7-10-3(V)), but a consumer-size grill cylinder in use is treated under the IFC open-flame-cooking limits, not the bulk-storage rule. Grills must be attended in use, kept clear of combustibles, and propane cylinders should be stored outdoors, upright, away from ignition sources.
