To file a noise complaint in New York City, call 311, use the 311 website, or submit through the 311 app. The city routes your report to either the NYPD or the Department of Environmental Protection (DEP) depending on the source of the noise, and the response you get depends on whether the sound is still happening when an officer or inspector arrives and whether it crosses the measurable limits set in the city’s Noise Code.1Department of Environmental Protection. Noise Code
How to File the Complaint
Every noise complaint in the city goes through 311. You can call, use the website, or use the 311 mobile app. When you file, include the exact street address of the noise source, the type of sound (construction, music, barking, mechanical equipment, lawn tools), the times of day it happens, and how long it typically lasts. The system issues a service request number so you can track the case online.1Department of Environmental Protection. Noise Code
One point of confusion worth clearing up: the NYC Noise app on smartphones is a data-logging tool, not a complaint system. It measures and records sound levels but does not open a 311 service request. If you want the city to act, you have to use 311 directly.
Who Responds, and How Quickly
The NYPD handles neighbor noise: loud music, parties, television, shouting, and similar sounds coming from a residence. Officers aim to arrive within 8 hours when no higher-priority calls are pending, and they can only act if the noise is still happening when they get there.2NYC311. Noise from Neighbor A party that ends before officers show up usually ends the case.
DEP handles commercial establishments, construction sites, air conditioners, and other mechanical sources. DEP responses often take longer because inspectors need to arrive with calibrated sound meters and take measurements that meet American National Standards Institute specifications.3NYC Department of Environmental Protection. New York City Noise Control Code For ongoing problems, like a rattling AC unit or a bar that plays loud music every weekend, file repeatedly with consistent details so inspectors can plan a visit when the noise is active.
What Actually Counts as a Violation
Knowing the thresholds helps you decide whether a complaint is worth filing and what to document. Section 24-218 of the Administrative Code defines unreasonable noise by comparing the sound to the surrounding ambient level, with different rules by time of day:4eLaws. New York City Administrative Code Section 24-218 – General Prohibitions
- Between 10 p.m. and 7 a.m., a continuous sound is a violation if it measures 7 dB(A) or more above ambient.
- Between 7 a.m. and 10 p.m., the threshold is 10 dB(A) or more above ambient.
- Sudden, sharp sounds (banging, slamming) violate the code at 15 dB(A) above ambient at any time.
Measurements can be taken inside your apartment or from at least 15 feet away on a public sidewalk or street. The lower nighttime threshold matters: a sound that was legal in the afternoon can be a violation at 11 p.m. without getting any louder.
Neighbor Music, TVs, and Instruments
These fall under the general rule in Section 24-218. There is no safe hour for practicing an instrument or playing a stereo. The test is whether the sound inside your unit exceeds the daytime or nighttime threshold.
Barking Dogs and Other Animals
Section 24-235 covers animal noise. If an animal’s sound is plainly audible inside your home and continues for 10 minutes or more during the day (7 a.m. to 10 p.m.) or 5 minutes or more at night (10 p.m. to 7 a.m.), the owner or caretaker is in violation.5American Legal Publishing. New York City Administrative Code 24-235 – Animals Time-stamped notes help: when the barking started, when it stopped, how often it repeats.
Window Air Conditioners and Fans
Section 24-228 sets a hard ceiling of 42 dB(A) for a circulation device as measured inside a neighboring dwelling, at least three feet from the nearest wall, floor, or ceiling.3NYC Department of Environmental Protection. New York City Noise Control Code That’s roughly the volume of a quiet library. A unit that rattles or vibrates against a window frame often fails. Central building HVAC and emergency equipment are exempt from this specific section, though they still fall under the general unreasonable noise rule.
Bars, Restaurants, and Nightclubs
Music from a commercial establishment cannot exceed 42 dB(A) inside any neighboring dwelling under Section 24-231.6American Legal Publishing. New York City Administrative Code 24-231 – Commercial Music A separate limit addresses bass: sound cannot exceed 45 dB in any one-third octave band between 63 Hz and 500 Hz. If what you feel in your floor is the thumping more than the melody, that bass provision is likely the relevant one.
Construction
Construction is permitted on weekdays between 7 a.m. and 6 p.m. No weekend work is allowed without special after-hours authorization.7American Legal Publishing. New York City Administrative Code 24-222 – After Hours and Weekend Limits on Construction Work Every site is required to have a written Noise Mitigation Plan available at the job site for DEP inspection.8American Legal Publishing. New York City Administrative Code 24-220 – Noise Mitigation Plan Weekend or late-night work without an authorization is a straightforward complaint.
Lawn and Leaf Equipment
Lawn mowers, leaf blowers, and similar tools cannot run before 8 a.m. or after 7 p.m. (or sunset, whichever is later) on weekdays. On weekends and state or federal holidays, the window is 9 a.m. to 6 p.m. or sunset.9NYC311. Noise from Lawn Equipment Parks Department crews may start at 7 a.m. on weekdays if they’re more than 300 feet from any residential building.
What the Offender Faces in Fines
If an inspection confirms a violation, the responsible party receives a notice of violation and a civil penalty from the schedule in 15 RCNY ยง47-02. The amounts vary by section and escalate with repeat offenses in that same section:10American Legal Publishing. 15 RCNY 47-02 – Noise Code Penalty Schedule
- General unreasonable noise under Section 24-218: $75 first offense, $150 second, $350 third.
- Animal noise under Section 24-235: $70 first, $140 second, $210 third.
- Commercial music under Section 24-231: $440 first offense, $880 second, $1,320 third. A business can avoid the first-offense fine entirely by making permanent soundproofing improvements within 30 days and certifying compliance to DEP. That mitigation option applies only to commercial music.
Repeat counts track each section separately. A bar fined under the commercial music section does not start at the second-offense level if it later gets a general unreasonable noise citation.
If the Case Goes to a Hearing
Violations are resolved at a public administrative hearing. Both sides can bring counsel, present evidence, cross-examine witnesses, and submit written arguments, and all testimony is under oath and recorded.11American Legal Publishing. New York City Administrative Code 24-263 – Hearings The hearing officer issues a written decision with findings of fact and conclusions of law. If sustained, a penalty from the schedule is imposed. Either side has 20 days to file written exceptions with the board, which can adopt, modify, or reject the officer’s findings.
If you’re the complainant, your contemporaneous records matter here: dates, start and stop times, how long each incident lasted, and the type of sound. The more consistent your documentation across repeated complaints, the more useful it is both for inspectors trying to catch the noise in progress and for any later hearing.
