How New York decides what counts as too loud
New York measures most residential noise relative to background level rather than against a fixed cap, so what counts as a violation depends on how quiet the surroundings already are.
Noise limits in New York
| Applies to | Daytime | Night |
|---|---|---|
| Residential (relative to ambient) | Not more than 10 dB above background, 7:00 AM – 10:00 PM | Not more than 5 dB above background, 10:00 PM – 7:00 AM |
| Construction | Not more than 10 dB above ambient, measured 15 ft from the source | Restricted; after-hours authorization required |
What's specific to New York
- Because the standard is relative to background noise, a reading that is legal on a busy avenue can be a violation on a quiet residential block.
- Abrupt, impulsive sounds from construction are treated separately from steady noise.
- DEP publishes a plain-language guide to the code that is easier to work from than the code text itself.
What New York residents most often report
- After-hours construction, which is the single largest category of 311 noise complaints in the city and usually turns on whether a variance was issued.
- Neighbour and party noise in multi-family buildings, routed to NYPD rather than DEP.
- Building mechanical equipment — HVAC, compressors, ventilation — which is judged against the ambient standard and is where a meter helps most.
How to measure it in New York
Take two readings, not one. Because the code compares the noise to background level, a reading of the source alone proves nothing — you need the ambient level from the same spot at a comparable time with the source off. Measure at your window or just inside the affected room, and note whether it was before or after 10:00 PM, since the allowance drops from 10 dB to 5 dB.
Record levels with the free online decibel meter, and log the date, start time and duration with each reading. A phone microphone is accurate to roughly ±2 dB and is not a calibrated instrument — enough to establish a pattern, not enough for an enforcement hearing.
Penalties in New York
Civil penalties vary by source and are set out in the code's penalty schedule; repeat violations escalate.
How to file a noise complaint in New York
Call or text 311, or file online. 311 routes the complaint to the responsible agency — DEP for most sound, NYPD for parties and street noise.
