Construction in The Bronx is limited to 7 AM-6 PM Monday through Friday under NYC Admin Code §24-223. Weekend, holiday, or after-hours work requires a DEP After Hours Variance (AHV). Major Bronx projects near Yankee Stadium, Hunts Point, and the Grand Concourse must comply with noise mitigation plans.
Section 24-223 of the NYC Admin Code prohibits construction noise between 6 PM and 7 AM weekdays and all day Saturdays, Sundays, and legal holidays without an After Hours Variance issued by DEP. Contractors must file a Noise Mitigation Plan under §24-220 for any project using equipment over 85 dBA. Jackhammers, pile drivers, and rock crushers have specific equipment-based dBA limits. Emergency work is exempt. DOB permit holders must post signs listing project hours, contractor name, and DEP complaint number. Common Bronx violations involve early-morning weekend work and exterior facade repairs without AHV.
Working without AHV: $3,200 first offense, $6,400 second, $8,000+ third. Missing noise mitigation plan: $880-$2,625. Stop-work orders can be issued by DOB for repeated violations.
