Who this helps: Renters, homeowners, and anyone in NYC losing sleep to summer noise — jackhammers before 7 a.m., a neighbor’s rooftop AC unit, a parked ice cream truck looping its jingle, or a private garbage truck grinding away at 4 a.m. This guide tells you exactly which complaint goes to which agency, what the law actually says, and how to file a 311 report that gets inspected instead of closed.
Summer is noise season in New York City. As the weather warms, 311 noise complaints climb — the city logged more than 610,000 noise complaints in 2024, according to reporting from Gothamist, and the warm-weather surge reliably begins in May. The problem isn’t just that there’s more noise. It’s that most New Yorkers file a complaint into the wrong system, describe it the wrong way, and never get an inspection. Here is how the city actually handles it — verified against the NYC Department of Environmental Protection (DEP) and NYC311.
The single most important thing: who handles your complaint
New York City splits noise enforcement between two agencies, and which one responds depends entirely on the source of the noise. Get this wrong and your complaint can sit in the wrong queue.
The DEP handles noise from equipment and machinery. According to NYC311’s noise complaints directory, the DEP responds to service requests for: air conditioner and ventilation equipment, boilers, construction, business equipment and generators, ice cream trucks, lawn and leaf-blower equipment, private garbage trucks, chronic alarms, dogs and other animals, and boats.
The NYPD handles noise from people and parties. Loud music from a neighbor or a club, banging and pounding, talking or television, street parties, and fireworks generally route to the police precinct rather than the DEP.
When you file at NYC311, the system asks you to pick a category — residential, commercial, streets and sidewalks, vehicles, construction. Choosing the right one is what sends your report to the agency that can actually act on it.
Construction noise: the 7 a.m. to 6 p.m. rule
This is the complaint that explodes every spring and summer. The rule, confirmed on the DEP’s Construction Noise Rules & Regulations page, is straightforward: construction is allowed on weekdays between 7 a.m. and 6 p.m. At all other times — before 7 a.m. or after 6 p.m. on weekdays, and any time on weekends — the contractor must apply for after-hours authorization (a “variance”) from the Department of Buildings or Department of Transportation.
There’s a narrower carve-out the DEP’s noise-code fact sheet spells out: professional construction work on a personal home is permitted on weekdays between 10 a.m. and 4 p.m., provided the house is at least 300 feet from a house of worship.
Every NYC construction site is also required to have a Construction Noise Mitigation Plan in place before work begins, with a copy available on site. And as of April 21, 2026, the DEP added new Construction Noise Monitoring Rule requirements for projects that operate under Alternative Mitigation Plans — meaning sites running on after-hours variances now face additional noise-monitoring obligations.
What to do if you hear illegal construction: If you hear construction before 7 a.m. or after 6 p.m. on a weekday, or any time on a weekend, and there is no posted after-hours permit, file a 311 construction-noise complaint while the noise is happening. A DEP inspector must observe the violation in person to issue a summons, so timing matters — a complaint filed during active noise is far more likely to result in enforcement than one filed the next morning.
Air conditioner and HVAC noise: there’s a decibel limit
Your neighbor’s window unit or a building’s rooftop HVAC system isn’t automatically legal just because it’s an appliance. Per the NYC Noise Code Fact Sheet, noise from a heating, air conditioning, or ventilation unit may not exceed 42 decibels (dBA) measured three feet from an open window of a nearby dwelling unit. The cumulative sound of multiple units in circulation is subject to additional restrictions.
This is a DEP complaint. File it under air conditioner or ventilation equipment, and note the days and times the noise is worst — the DEP uses that pattern to schedule an inspection when the unit is actually running.
The ice cream truck rule almost nobody knows
Here’s one that surprises people every summer: under the NYC Noise Code, food vending vehicles may only play their jingle or music while the vehicle is in motion. A parked, standing, or stopped ice cream truck looping its jingle is violating the law. NYC311’s ice cream truck noise article confirms you can report music or a jingle from a truck that is parked, standing, or stopped. This, too, is a DEP complaint — and a DEP inspector must witness it in person to act.
Private garbage trucks at 4 a.m.
Commercial waste haulers servicing businesses overnight are a major source of early-morning noise complaints. The Noise Code sets hard limits: a private garbage truck’s noise cannot exceed 80 dBA measured 35 feet from the source, and operation is prohibited within 50 feet of residential properties between 11 p.m. and 7 a.m. if the sound exceeds 80 dBA at that distance — except during an emergency or storm. Report these to the DEP under private garbage truck noise, with the time and location.
A note on the NYC Noise app — it does NOT file complaints
The DEP offers a free mobile app called NYC Noise for iPhone and Android. It’s worth knowing what it is and isn’t: per NYC311, the app is for data collection only and does not submit complaint service requests. It logs decibel levels, time, and source to help the DEP map noise hotspots — but if you want an inspection, you still have to file through 311. Don’t assume tapping the app counted as a complaint.
How to Take Action
1. Identify the source first. Equipment, construction, vehicles, animals → DEP. People, parties, loud music, banging → NYPD. This determines everything.
2. File the complaint while the noise is active. Call 311 (or 212-639-9675 / 212-NEW-YORK from outside the city), use the NYC311 online portal, or the NYC311 mobile app. Service is available 24/7 in more than 200 languages, and you can file anonymously — though leaving contact information lets the responding agency follow up with you.
3. Be specific. Give the exact address, the type of noise, and the days and times it recurs. For equipment and HVAC complaints, a recurring pattern helps the DEP schedule an inspection for when the noise is happening.
4. Save your Service Request number. You can look up the status at the NYC311 Look Up Service Requests page. If a DEP inspection is completed, you can request a Noise Inspection Report by emailing the DEP with your service request number and the inspection date.
5. For chronic neighbor noise, consider mediation. NYC311 notes that free mediation may be an option for ongoing disputes — a way to resolve recurring issues with a neighbor, landlord, or business without repeated enforcement calls.

Frequently Asked Questions
Does the DEP or NYPD handle loud music from a bar? A bar, club, or restaurant noise complaint generally routes through NYC311’s commercial category. Loud music from a neighbor or on the street typically goes to the NYPD; equipment and commercial-establishment sound levels can involve the DEP. When in doubt, file through 311 and select the most specific category.
Can I file a noise complaint anonymously? Yes. NYC311 lets you file anonymously, but providing contact information helps the responding agency follow up and, for DEP cases, arrange an inspection.
Why was my noise complaint closed with no action? For DEP-handled noise (construction, HVAC, ice cream trucks), an inspector must personally observe the violation to issue a summons. If the noise had stopped by the time an inspector arrived, the case may close without a finding. Filing while the noise is active — and noting recurring times — improves your odds.
Is the NYC Noise app the same as filing a 311 complaint? No. The DEP’s NYC Noise app collects noise data only and does not create a complaint service request. To request enforcement, file through 311.
