Summary

Unincorporated Pinal County's noise ordinance does not reach aircraft. County Code Section 10-27(12) exempts any aircraft operated in conformity with federal law, federal air regulations, or air traffic control instructions, including aircraft responding to a federally declared emergency, from the county's excessive-noise standards entirely.

These county ordinances apply to unincorporated areas of Pinal County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Any aircraft operated in conformity with, or pursuant to, federal law, federal air regulations or air traffic control instructions issued pursuant to or within duly adopted federal air regulations, together with any noise created by aircraft operated under, or pursuant to, declaration of an emergency under federal air regulations;

Full Breakdown

The aircraft exemption is one of fourteen exemptions listed in Section 10-27, and it is written as near-total deference to federal airspace regulation rather than a county-set noise limit: any aircraft flying in conformity with federal law, FAA regulations, or air traffic control instructions is exempt, and the exemption separately extends to aircraft operating under a declared federal emergency. Nearby exemptions in the same list give context for how narrowly the county otherwise carves out exceptions: item (13) exempts only special events approved by the board of supervisors, and item (14) caps motorized sporting events that clear site-plan review at 120 decibels at the property line, rather than exempting them outright.

Aircraft is treated more generously because county governments do not have authority to regulate flight noise, which is federally preempted. The exemption is directly relevant to unincorporated county land near general-aviation traffic and Pinal Airpark operations. S. Section 11-251(31).

Violations & Fines

Because aircraft operated under federal air regulations is fully exempt under Section 10-27(12), the county cannot cite an aircraft operator under Section 10-28 for engine or flyover noise. The Class 1 misdemeanor disorderly-conduct charge under A.R.S. Section 13-2904 and the civil infraction fines of up to $750.00 per day under Section 10-28 remain reserved for non-exempt excessive-noise sources reached by Sections 10-21 and 10-24, not for federally regulated flight operations.

Frequently Asked Questions

Can Pinal County cite a pilot for a loud flyover?
No. Section 10-27(12) exempts any aircraft operated in conformity with federal law, federal air regulations, or air traffic control instructions from the county's noise chapter entirely, so flyover noise is regulated by the FAA, not the county.
Does the exemption cover Pinal Airpark or other airport operations in the unincorporated county?
It covers aircraft operated under federal air regulations, which includes flight operations at airports in the unincorporated county; the exemption turns on the federal authorization the aircraft is operating under, not the specific airport.
What about noise from an emergency flight?
Section 10-27(12) separately exempts noise from aircraft operated under, or pursuant to, a declaration of emergency under federal air regulations, so emergency flight operations are exempt on the same basis as routine federally authorized flights.
Is any aviation-related noise still enforceable by the county?
Ground noise or activity that is not aircraft operated under federal air regulations, such as unrelated ground equipment, falls outside the Section 10-27(12) exemption and remains subject to the ordinary Table 1 limits and Section 10-28 penalties like any other source.
