New York City Noise Ordinance: What You Need to Know (2026)

New York City's noise code is one of the most comprehensive in the nation. Officially known as the NYC Noise Code (Local Law 113), it covers everything from construction noise to ice cream truck jingles. Given the density of the city and the proximity of residential, commercial, and industrial uses, the code attempts to balance urban life with residents' right to reasonable quiet. Understanding the basics can help you navigate noise issues whether you live in Brooklyn, Queens, Manhattan, or anywhere else in the five boroughs.

How the NYC Noise Code Works

The NYC Noise Code sets specific decibel limits based on the time of day and the type of noise source. For general noise in residential areas, the code uses a standard based on the ambient noise level plus an allowable increase. In practice, this means that noise from any source should not exceed the existing background noise by more than 10 dB during the day (7 AM to 10 PM) or 5 dB at night (10 PM to 7 AM). The code also sets absolute limits for specific sources, such as music, construction equipment, and commercial operations.

Quiet Hours and Residential Protections

While the code applies 24 hours a day, the stricter nighttime standards effectively create quiet hours between 10 PM and 7 AM. During these hours, amplified music that is audible from 15 feet away in a residence is considered a violation. Dog barking that continues for 10 minutes or more is also a violation under the code. Air conditioning units must meet specific decibel limits when measured from a neighboring window. These provisions apply citywide, including in all five boroughs.

Construction Noise

Construction noise is the single most regulated category in the NYC Noise Code. Standard construction hours are weekdays from 7 AM to 6 PM. Any work outside of these hours requires an After Hours Variance (AHV) from the Department of Buildings. The code also requires a noise mitigation plan for large construction projects, and certain equipment (such as pile drivers and concrete breakers) must meet specific decibel limits at the nearest residential facade. Construction noise is the leading source of 311 noise complaints in New York City.

How to File a Complaint

Noise complaints in NYC are filed through 311 (phone, website, or app). The complaint is routed to the appropriate agency based on the source. The Department of Environmental Protection (DEP) handles most noise enforcement, including construction noise, commercial noise, and certain residential noise issues. The NYPD handles noise complaints related to parties, bars, and other social gatherings. Response times vary depending on the priority and the time of day.

Penalties and Enforcement

The NYC Noise Code carries significant penalties. First-time violations for unreasonable noise can result in fines of $350 or more. Construction noise violations can reach $8,000 per offense, with repeat offenders facing even higher penalties. The DEP employs noise inspectors who carry calibrated sound measurement equipment and can issue violations on the spot. The combination of high fines and active enforcement makes NYC's noise code one of the most consequential in the country.
