Can I have an outdoor fireplace or chiminea?

Open Burning is allowed at single-family homes, duplex and town homes without a permit, provided these regulations are met:

  • Only small fires are allowed (maximum 3-foot diameter by 2-foot height) that are contained in a non-combustible chiminea, outdoor fireplace, fire pit, or other approved method.
  • All openings in the container must be covered with wire mesh or other screening materials that will prevent the passage of sparks and embers.
  • Fires must be kept at least 15 feet from structures.
  • Fires must be constantly attended.
  • The burning of yard waste, leaves, garbage, or other rubbish is prohibited in the City of Thornton, unless specifically exempted.

All other burning requires a permit from the Thornton Fire Department.  For a brochure on Open Burning Regulations, please visit the Fire Department website.  If the open burning regulations are not being followed, please call 9-1-1 to report the danger. 

We often receive calls from citizens inquiring about their neighbors and offensive smoke. The Fire Department can order any fire to be extinguished that does not comply with all regulations, creates a hazardous condition, or poses a health risk.  We generally do not intervene if there is only an unpleasant odor or drifting smoke. For more information, please call our main phone number at 303-538-7602, or visit the Fire Department website.
