Caldwell, ID Outdoor Cooking: Smoker Rules (2026)

Caldwell City Code 08-17-01 provides that the open-burning article does not prohibit outdoor fireplaces, barbecue pits or grills used in preparing food or for recreational purposes, and 08-17-03 lists barbecues and other fires used in the preparation of food among allowable fires that need no permit. A wood, pellet, charcoal or propane smoker used to cook food therefore qualifies as a cooking fire and does not require a burn permit. Under 08-17-03(4), if a cooking fire exceeds three feet (3') in diameter and two feet (2') in height, a Caldwell Fire Department permit is required, so very large pit smokers or whole-hog burn pits could cross that threshold; ordinary backyard smokers do not. All cooking fires must be attended by a competent adult and must not create a hazard or nuisance. Because smokers produce continuous smoke, the practical constraint is Caldwell's nuisance standard: persistent heavy smoke drifting onto neighboring property can be addressed as a nuisance even though the cooking activity itself is allowed. Smokers should be operated outdoors away from structures and overhangs, and propane- or wood-fueled units remain subject to the adopted International Fire Code for fuel handling. The air-quality and wind burn-ban triggers that govern open burning do not prohibit ordinary food smoking.
