Alpharetta, GA Noise Ordinances: Amplified Music & Outdoor Sound (2026)

Section 26-114(f) of the Alpharetta Code targets amplified sound specifically within an MU-zoned master planned project: it is unlawful for a commercial or business establishment there to employ any machine, device or instrument for producing, reproducing or amplifying sound, including radios, televisions, stereos, musical instruments, amplifiers, loudspeakers or recorded-music players, at a volume that creates sound plainly audible within a residential dwelling unit 100 feet or more away, between 11:00 p.m. and 7:00 a.m. Sunday through Thursday, and between midnight and 7:00 a.m. on Saturday and Sunday.

The code defines 'plainly audible' as sound whose information content, such as understandable speech, a raised voice, repetitive bass, or musical rhythm, is distinguished by a listener with normal hearing without any listening device. Separately, section 26-115(b)(9) exempts events with amplified sound from the general sound level limits of section 26-114(a) when the event operates within the time and volume parameters set out in an approved special administrative permit, giving event organizers a compliance path other than the numeric decibel table. Section 26-118 lets the police chief or a designee grant special variances from the noise article generally, weighing hardship to the applicant against the health, safety and welfare impact on affected persons, with any granted variance carrying conditions and a time limit.
