The department regulates all open outdoor fires. The purpose of this program is to limit the emissions of air contaminants that are produced from open burning. Below contains a partial list of the kinds of burning activities, whether they require permits and the restrictions on them. Some restrictions apply throughout Maricopa County, and some apply only in Area A. For an interactive map of Area A, see Planning Area Maps.
To determine high pollution advisory days you can sign up for email or text alerts, download the Clean Air Make More Mobile App, or call the burn restrictions update line at 602-506-6400 to find out if burn restrictions are in place.
Household Waste and Yard Waste
