Alpharetta, GA Noise Ordinances: Quiet Hours (2026)

Fulton County's noise rules are in Part II, Chapter 46 (Offenses), Article III, Division 2 of the Code of Ordinances, with the core prohibition at Sec. 46-144 (Loud, disturbing, unnecessary noise). The ordinance prohibits any noise that is loud, disturbing, or unnecessary and that interferes with the comfort, repose, health, or safety of others within unincorporated Fulton County. Common enumerated nuisances include amplified music, motor vehicle sound systems audible at a distance, construction outside permitted hours, barking dogs, and outdoor power equipment used at night. The ordinance is enforced primarily through a plainly audible standard at or across a residential property line, with heightened enforcement during typical nighttime hours (commonly 11:00 PM to 7:00 AM). State law O.C.G.A. §16-11-39 (disorderly conduct) and §40-6-14 (motor-vehicle sound) provide parallel authority. The cities of Atlanta, Sandy Springs, Roswell, Alpharetta, Johns Creek, Milton, Mountain Park, College Park, East Point, Hapeville, South Fulton, Union City, Fairburn, Palmetto, and Chattahoochee Hills each maintain separate noise ordinances that apply within their limits.
