Aircraft noise in Maricopa County is federally regulated by the FAA and exempt from the county noise ordinance (P-23, Section VI.A.1). Noise from aircraft in flight and sounds originating at airports related to flight operations are explicitly exempt. Unincorporated areas near Phoenix Sky Harbor, Deer Valley, Falcon Field, and other airports experience aircraft noise but the county has no authority to regulate it.
Aircraft noise in Maricopa County is exempt from the county noise ordinance P-23 under Section VI.A.1, which excludes sounds from aircraft in flight and airport-related flight operations. Maricopa County has an unusually high concentration of airports and airfields including Phoenix Sky Harbor International, Phoenix-Mesa Gateway, Deer Valley, Falcon Field, Glendale Municipal, Goodyear, Buckeye, and several smaller general aviation airports. Unincorporated areas near these facilities, particularly around Deer Valley and Falcon Field, experience significant aircraft noise from flight training operations. The FAA controls aircraft noise through Part 150 noise compatibility studies and flight path management, and residents have no county-level recourse for aircraft noise complaints. Homes within Airport Vicinity Overlay zones in the MCZO are subject to sound attenuation construction requirements to reduce interior noise levels.
Specific penalty amounts for this ordinance are not published in a publicly accessible fine schedule. Contact Maricopa County code enforcement directly for current fines, enforcement procedures, and hearing options.
