DEQ monitors daily air quality and weather conditions throughout the state to evaluate whether outdoor open burning should be limited to protect public health. Local ordinances may also restrict or prohibit open burning due to air quality or fire safety conditions.
If you live within the boundaries of an Indian reservation, check with your tribal air quality office before burning.

Residential backyard burning of natural vegetation such as tree leaves, branches, yard trimmings, or gardening waste is allowed in most areas of Idaho under specific conditions.
Residential burning is allowed only on the property where the waste was generated and if house-to-house solid waste collection service is unavailable. Burning is always prohibited when DEQ has issued a burn ban.
Training fires are allowed if conducted by qualified personnel to train firefighters in methods of fire suppression and firefighting techniques or to display certain fire ecology or fire behavior. The responsible agency conducting the training fire is required to notify a DEQ regional office prior to igniting and must ensure that the site has been certified free of asbestos and lead paint prior to burning.
Training fires are always prohibited when DEQ has issued a burn ban.
Infrequent burning of agricultural and silvicultural waste, land clearing debris, diseased trees, or debris from emergency cleanup operations is allowed at landfill disposal sites. Basic smoke management practices must be included in the facility’s approved Operations Plan and adhered to when burning.
Landfill disposal site burning is always prohibited when DEQ has issued a burn ban.
Unless specifically allowed by the “Rules for the Control of Air Pollution in Idaho” (IDAPA 58.01.01), burning waste generated from business, trade, or industry is prohibited. This includes trade wastes generated during construction, renovation, demolition, or repairs.
Always check with your local fire department before burning. A permit from your local fire department or the Idaho Department of Lands may be required. Fire safety concerns may prohibit open burning.
Fire safety permit holders must also comply with DEQ rules and any local ordinances and are never allowed to burn any prohibited materials or burn if a burn ban is in effect.
