Fireplaces, Fire Pits, and Chimineas During the Holidays

What is a No Burn Day? When air pollution levels are on the rise and weather conditions create dry, stagnant air, the Maricopa County Air Quality Department will issue a "No Burn Day." Restrictions last for a 24-hour period, starting at midnight, and include a ban on woodburning activity including fireplaces, fire pits or open outdoor fires.

The purpose of the No Burn Day restriction is to avoid adding pollution to our air when the forecast suggests air quality will approach or exceed the federal health standard. Learn more at Fireplaces and Winter Air and Residential Wood-Burning Q&A.
