Burn Permits

Below is the Burn Permit information provided from Larimer County Burn Brochure

How to Get a Burn Permit

1. Access the burn permit application online from Larimer County Department of Health and Environment (LCDHE) or call 498-6775 for assistance. Digital photos can be uploaded to assist in the review and approval process avoiding a possible site inspection. A permit must be renewed each year.

2. LCDHE will evaluate and process the application. It will be forwarded to your local fire authority for their approval also. You will get the Permit via an email attachment if you can include/provide an email address, or it is mailed via the USPS.

3. To see if the permit has been approved or denied you can track its’ progress online. Some applications require a site visit; all permits require fire authority approval.

4. Your local fire authority has final approval determination on the application based on any fire restrictions.

5. Once a Permit is in your possession, call the appropriate communication center each day prior to ignition (phone number listed on the permit). This prevents a fire department from responding to a report of smoke at the location of an approved burn.

6. Keep a copy of your burn permit on site when you are burning. A valid permit will have authorization from both the health department and the fire department.

Air Quality

Most outdoor burning in Larimer County requires a permit signed by both the Fire Department and the Health Department. The fire department evaluates applications for potential fire safety issues, while the health department evaluates applications for air quality issues that can impact human health. For example, open burning releases fine particulates that can aggravate chronic lung diseases and carbon monoxide that can prevent the transport of oxygen in the blood.

Open burning in Larimer County is regulated by the Colorado Department of Public Health and Environment/Air Pollution Control Division and the Larimer County Department of Health and Environment under Colorado Air Quality Control Commission’s Regulations # 1 and # 9. Open burning without a permit is illegal and can result in fines of up to $10,000 per day. For info go to:
