Summary
In unincorporated Maricopa County, it's illegal to run a bar or nightclub's radio, loudspeaker, or sound amplification equipment so loudly it can be heard inside a closed home within 500 feet of the property line.
It shall be unlawful for any person to operate any radio, loudspeaker, musical instrument, or other sound producing, sound reproducing, or sound amplification equipment which emits noise that can be heard from within closed residential structures located within 500 feet of the boundary of the property from which such noise emanates.
Full Breakdown
Maricopa County's noise ordinance, P-23, makes it unlawful to operate a radio, loudspeaker, musical instrument, or other sound-amplification equipment that emits noise audible inside a closed residential structure within 500 feet of the property line: a standard that reaches bar and nightclub sound systems in unincorporated areas. A separate public-disturbance clause exempts noise from the normal conduct of business during that business's customary hours, so daytime service isn't targeted, but amplified music carrying into nearby homes late at night is. The Sheriff's Office administers the ordinance and can issue a written warning before pursuing a misdemeanor charge in Maricopa County Justice Court.
Violations & Fines
Violating this section is a misdemeanor: fines run up to $300 for a first offense, $500 for a second, and $750 for a third or later offense, with each day treated as a separate violation.
