Commercial establishments in The Bronx must comply with NYC Admin Code §24-231, limiting music and amplified sound to plainly-audible standards. HVAC, refrigeration, and loading-dock noise are regulated separately under §24-227 and §24-233. DEP enforcement is aggressive in mixed-use Bronx neighborhoods.
Commercial music cannot exceed 42 dBA inside any nearby residential dwelling between 10 PM-7 AM or 45 dBA otherwise. Circulation devices (HVAC, refrigeration) cannot exceed 45 dBA at a residential property line. Refuse collection after-hours in commercial zones requires DSNY authorization. Bronx businesses along Fordham Road BID, Hub (149th Street), and Bruckner Boulevard corridors face recurring DEP inspections. OATH Environmental Control Board adjudicates disputed summonses.
Commercial music: $350-$2,400 first, up to $8,000 chronic. HVAC/refrigeration excess: $880-$2,625. Construction/refuse noise: $440-$1,750.
