Outdoor amplified music in Boston requires an APCC noise variance and a Special Event permit. Unpermitted outdoor events are limited to the plainly audible 50-foot standard and must stop by 11 PM.
Outdoor concerts, festivals, block parties, and restaurant patio DJ events in Boston need layered approval. Event organizers file with the Office of Special Events for street closures and permits, obtain an APCC noise variance for amplified sound exceeding 70 dBA, and secure a Boston Licensing Board entertainment permit if admission or alcohol is charged. Patio music at City Hall Plaza, Faneuil Hall, and along the Greenway follows site-specific terms. Residential backyard gatherings do not need a permit but must follow general noise rules and stop amplified music by 11 PM (10 PM on Sunday through Thursday in practice per ward expectations).
Specific penalty amounts for this ordinance are not published in a publicly accessible fine schedule. Contact Boston code enforcement directly for current fines, enforcement procedures, and hearing options.
