Why do I need an Open Burn Permit?

Unless specifically exempted by rule,1 persons setting outdoor fires, by law,2, 3  must obtain a permit from ADEQ or a delegated permitting authority. These laws are intended to help protect the public from smoke impacts. Two types of open burn permits are issued in Arizona: Open Burn Permit and Dangerous Materials Open Burn Permit. 

Open Burn Permit

An Open Burn Permit is needed for open outdoor fires for the purposes of weed abatement, prevention of a fire hazard or instruction in the methods of fighting fires, unless conducted by a public officer in the performance of an official duty.

If your burn will take place in Maricopa, Pima or Pinal County, you must apply with that county:

In some locations outside these counties, fire departments and local governments have authority to issue open burn permits | See Jurisdiction List for County Open Burn Permit Information >

Only ADEQ has authority to issue open burn permits for dangerous materials.

Can I Burn Household Trash?

Unless certain criteria are met,4 by law, household trash may not be burned, and should be disposed by way of waste collection systems.

How Can I Conduct Burning?

Material to be burned must be either piled, collected in a pit or ditch, field burned (agricultural only), or burned using an approved waste burner. An approved waste burner means an incinerator constructed of fire resistant material with a cover or screen that is closed when in use, and has an opening in the sides or top no greater than one-inch in diameter. The open burn permit will specify the allowable methods that can be used for burning.
