​Fire Restrictions -  

Open burning is allowed at single-family homes, duplexes, and townhomes 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 open burning requires a permit from the Thornton Fire Department.
