Is Open Burning Legal in Arizona After the 2026 Law Changes?

It is strictly regulated.

Arizona permits open burning only under stringent conditions, with local air quality districts enforcing near-universal prohibitions. The Arizona Department of Environmental Quality (ADEQ) and county environmental offices restrict most open burning to agricultural, silvicultural, or fire-fighting exemptions, while residential burning faces near-total bans. Recent 2026 compliance shifts under ADEQ’s revised Rule 310 (Particulate Matter) tighten enforcement, particularly in Maricopa, Pima, and Yuma counties where air quality nonattainment persists.


Key Regulations for Open Burning in Arizona

  • Permit Requirements: Open burning mandates prior approval from ADEQ or county environmental agencies, with applications scrutinized for smoke impact zones. Agricultural burns require pre-notification to local fire departments under Arizona Revised Statutes § 37-361.
  • Prohibited Materials: Burning household waste, treated wood, tires, or construction debris is illegal statewide. Violations trigger fines up to $25,000 under ADEQ’s 2024 Penalty Policy, with repeat offenders facing escalated enforcement.
  • Seasonal Restrictions: Burning is largely prohibited during high-pollution months (May–October) in nonattainment areas, aligning with EPA’s 2026 ozone standards. Exemptions apply only to certified prescribed burns with approved burn plans.
