Open Burning Permits in Larimer County

Most outdoor burning requires a permit from both your local fire department and the Larimer County Department of Health and Environment (LCDHE). The fire department checks for fire safety risks, and the health department reviews air quality concerns that could affect people's health.

Open burning is regulated by the Colorado Department of Public Health and Environment (CDPHE) under air quality rules. The Larimer County Health Department enforces these rules, including regulations about burn permits and illegal burning. The Larimer County Sheriff’s Office or local fire departments enforce these rules for areas outside of city limits.

Please Note: Burning without a permit is illegal and can lead to fines up to $10,000 per day.

Things to know before applying for a Burn Permit

Anyone planning to burn outdoors in Larimer County must follow all local, state, and federal rules. It’s your responsibility to understand the air quality rules and any restrictions for open burning. You can review local and state regulations, common exemptions, and other resources below.

About Burn Permits

Open burn permits are typically used for wildfire prevention or land management by property owners in the mountains. These permits are usually limited to 50 slash piles or fewer per year. If you need to burn more than 50 piles, you will need a Smoke Management Permit from CDPHE. Slash is defined as woody material (branches, limbs, and stems) under six inches in diameter, free of dirt. It does not include tree stumps, roots, or other materials.

Notifying Local Agencies

For safety reasons, anyone planning to burn (including agricultural burns, bonfires, or non-commercial cooking fires) should fill out a burn permit application. This helps local fire departments or the Sheriff’s Office review the plan. Fire departments may have specific rules for burning in their areas, so it's a good idea to contact them directly if you have any questions. For more details, please review the Open Burn Permit Regulations and Guidelines below.

Alternative Disposal Options
Before burning, consider other ways to dispose of natural woody or vegetative materials, like mulching, recycling, or reusing. These options may be safer and more environmentally friendly.
