From bonfires to agricultural open burns, citizens must have approvals from both health and fire officials. If you’re a resident of Broomfield, Boulder, Jefferson or Weld County, you should first contact your county’s health department. Adams County residents should contact the Colorado Department of Public Health and Environment Department.
After the health department approves the burn, residents need to contact North Metro’s Fire Prevention Division at (720) 887-8217 to obtain and complete an open burning application.

All open burning shall be conducted in accordance with the adopted fire code as enforced by North Metro Fire, with emissions standards as administered by the applicable county health department or the State of Colorado (where there is no county health department), and with regard to public safety as determined by the county sheriff.
Under the authority of the adopted fire code, North Metro Fire may ban all open burning for reasons deemed necessary (i.e., high fire danger, high winds, county burn bans or fire restrictions, etc.). Fire and weather conditions change constantly and are continuously evaluated by Fire Prevention Division staff throughout the day.
The county health department is also empowered to ban all open burning for reasons deemed necessary, such as poor air quality, etc. Please contact the Clean Air Advisory Line at (303) 758-4848 to determine if open burning is permitted.
Furthermore, the county sheriff may also ban all open burning for reasons deemed necessary. Notification of such a ban is provided via a press release to local newspapers with a copy provided to the fire jurisdiction(s) affected. The information can also often be found on the county sheriff’s website.
