Construction hours in New York County, NY — sometimes called construction noise rules or contractor work-hour ordinances — set when contractors can run power tools, hammers, and heavy equipment.
Manhattan construction limited to 7 AM to 6 PM weekdays per NYC Noise Code. After-Hours Variance (AHV) permits required for weekend and nighttime work. DOB enforces with significant fines.
Manhattan construction noise is regulated under NYC Administrative Code §24-222 and the Noise Code. Standard permitted hours are 7 AM to 6 PM weekdays. Saturday, Sunday, holiday, and after-hours work requires an After-Hours Variance (AHV) from the Department of Buildings. AHV permits specify allowable activities and noise mitigation measures. NYC DOB and DEP jointly enforce construction noise. Manhattan's continuous development means construction noise is a pervasive issue. Pile driving, jackhammering, and other high-impact activities have additional restrictions. Community boards provide input on AHV applications.
After-hours without AHV: up to $8,000. Noise Code violation: $350 to $8,000. DOB stop-work order possible. Repeat violations: escalating penalties.
