Open burn smoke permits


Due to continuing concerns with the COVID-19 pandemic and its associated threat to people with heart and/or lung disease, the Colorado Department of Public Health and Environment recommends reducing open burning at this time, if possible, to lower the potential for additional respiratory effects from smoke. If open burning is conducted, please be considerate of nearby residents, especially those who may be suffering from cardiac or respiratory ailments.


Open burn smoke permits are for 50 or fewer piles to burn in the current calendar year and each pile is small enough that it will be out cold by sunset. Pile size is limited to 8'x8'x8' (512 cubic feet).Larger burns may require a smoke management permit.

If you wish to open burn in the following counties, please contact the local county health department for a permit:


All other counties require a state permit. Please apply below.
