Washington County, UT Fire Regulations: Outdoor Burning (2026)

Section 4-4-1 sets the closed fire season during the statutorily closed period from June 1 through October 31 and the regulatorily closed period from November 16 through the last day of February, during which burning is prohibited except where state statute allows it, and then only if the person obtains a state-issued closed-season burning permit before burning and notifies the local fire authority of the approximate burn time beforehand. Section 4-4-2 covers the open fire season, March 1 through May 30 and November 1 through November 15, during which a person must obtain a county burning permit before starting a fire in the unincorporated areas of the county.

Section 4-4-3 carves out agricultural and horticultural exceptions to both seasons for burning prunings, dead or diseased trees and stubble, ditch bank weed growth, and controlled orchard frost-protection heating, though the pruning exception still requires a permit in residentially zoned areas during the regulatorily closed season. Section 4-4-5 puts the chief fire officer of each fire protection entity serving the unincorporated county in charge of signing and issuing open-season burning permits, and bars any permit issuance during closed season or whenever the clearing index is below 500.
