Open Burns

Permit Types: 
General Open Burn Permits:
Residents in all other areas of Larimer County must obtain a General Open Burn Permit for mountain slash piles. These General Open Burn Permits have a limit of 50 slash piles or less per year. Slash is defined as clean, dry branches four inches or less in diameter, not containing other smoke producing materials. Applications will not be processed until one week before the start of the open burn period.

Specialty Burn Permits:
A Specialty Burn Permit must be obtained for conducting agricultural ditch burns, bonfires, or other fires containing non-prohibited materials. These types of permits are reviewed by the local fire department. Attaching digital photos for review of material types and specific safety guidelines is encouraged and may expedite the permitting process.
