Suffolk County has no county-level amplified sound ordinance — regulation is municipal. In Boston, outdoor amplified music requires an Entertainment License from the Mayor's Office of Consumer Affairs & Licensing under Boston Municipal Code §17-17, and public-space amplification requires a separate permit from Boston Parks & Recreation or the Public Improvement Commission. Boston Municipal Code §16-26 caps residential sound at ambient +10 dB at the property line. Chelsea, Revere, and Winthrop each require special event permits for amplified public sound. ABCC-licensed establishments (bars, clubs, restaurants with liquor licenses) must comply with license-specific noise conditions administered locally through the Boston Licensing Board or equivalent. Live-music venues in Boston's entertainment districts (Theater District, Fenway, Seaport) face enhanced scrutiny. MGL c. 272 §53 disturbing-the-peace charges can be brought by any Massachusetts police officer regardless of local ordinance.
Unpermitted amplification in Boston: $100-$300 plus license suspension risk. Repeat noise violations can trigger entertainment license review or revocation by the Boston Licensing Board. MGL c. 272 §53 disturbing the peace: up to $150 fine or 6 months imprisonment.
