The fire burnpermit is free and required under Idaho law for any burning outside city limits stateside (excluding campfires) from May 10 through October 20. However, some cities and other jurisdictins - including local or county fire departments, Idaho DEQ, Tribal Reservations, and others - may have additional or alternate permit systems in place.
For questions regarding burn permits, contact the Idaho Department of Lands Fire Management Bureau at this Contact link. If after hours or no answer, please contact your local Fire Department or Sherriff's office.
Burning can be limited based on current fire restrictions. This Web site provides information about most current fire restrictions, but check with your local fire department for other restrictions that may be in place at the time you want to burn.
Also, compliance with air quality regulations is required at the time of burning. You can check air quality conditions online, call the DEQ office in your area before burning, or contact the appropriate Tribe if you plan to burn within Reservation boundaries.
