Spring in New York City brings two things to every block: more people on the sidewalk, and more trash hitting the curb at the wrong time. If you have ever walked past a heap of contractor bags, an uncovered mattress, or a refrigerator with the door still attached, you have already seen the kind of violation that NYC’s Department of Sanitation (DSNY) wants you to call in. The catch — most New Yorkers don’t know which complaints DSNY will actually act on, and which ones get closed without an inspection.
This is the 311 lane HelpNewYork owns. Below is exactly what you can report, what you can’t, and how the city’s 2024 commercial bin mandate has changed enforcement going into the warmer months of 2026.
Why illegal dumping and waste complaints matter right now
NYC311 routes Trash, Recycling, or Compost Disposal complaints directly to DSNY for inspection and potential fines, and the agency now operates a dedicated Illegal Dumping category with two descriptors — “Removal Request” and “Chronic Dumping” — so residents can flag both one-off pileups and ongoing problem locations. DSNY publishes the program at nyc.gov/dsny, including the Illegal Dumping Award Program that pays out a portion of recovered fines to residents whose tips lead to a conviction.
Brooklyn historically files the most complaints across this category, with reported hotspots in Bushwick and parts of Coney Island, according to DSNY enforcement reporting. But the most common 311 complaints in this lane are far more ordinary: trash bags put out three hours too early, an uncovered mattress, or a commercial business still using black bags after the city’s containerization deadline.
What you CAN report through 311 — DSNY will respond
Per the official NYC311 guidance at portal.311.nyc.gov, the following are valid, actionable complaints in 2026:
Set-out time violations
Residential buildings of any size have two legal set-out windows:
- After 6 PM — if waste is in a bin of 55 gallons or less with a secure lid
- After 8 PM — if bags are placed directly on the curb
- All waste must be set out by midnight to be collected
If a neighbor consistently puts bags out at 3 PM, that’s a reportable violation. One-time set-outs are not actionable — 311 requires a chronic pattern, and you must include the specific days and times.
Bins left out after pickup
If pickup happens before 4 PM, residential bins must be retrieved by 9 PM the same day. If pickup is after 4 PM, residents have until 9 AM the next morning. Commercial bins must be cleared by the time the business reopens.
Loose trash
Open bags, unfastened bin lids, and refuse that isn’t tied or bundled all qualify. This is one of the most underused 311 categories — and one of the most reliable for triggering a DSNY inspection.
Mattress or box spring not sealed
City rules require any mattress or box spring to be fully sealed in a plastic bag before being placed at the curb. DSNY will not collect an uncovered or partially covered mattress, and a chronic offender can be reported.
Refrigerator or freezer with door attached
Property owners must remove all doors and locking devices before placing a refrigerator or freezer curbside. A refrigerator with the door still on is both a 311 reportable violation and a child-safety hazard.
Construction debris mixed with household trash
Sheetrock, tiles, concrete, bricks, tubs, sinks — none of it can go out with regular residential trash unless you live in a 1- to 2-family home AND did the work yourself with no paid help. Hired-contractor debris is commercial waste and must be hauled by a private carter or in a dumpster.
Business without a private carter or carter decal
Every NYC commercial business must either hire a private carter or register as a self-hauler with the Business Integrity Commission. Businesses must also post a decal showing the carter’s name and pickup schedule. Missing decals and missing carters are both reportable.
The 2024 commercial bin rule
As of March 1, 2024, every business in NYC must place trash for collection in a bin with a secure lid — regardless of what the business sells. Recycling can still go in bags or bundles after 8 PM, but perishable material must be containerized. If you have watched a commercial corridor go from a wall of black bags to a row of standardized bins over the last two years, this is why.
What you CAN’T report (and what to call instead)
- A one-time issue. You need a chronic pattern with dates and times.
- Bags on the property’s collection day — unless the sidewalk is completely blocked.
- Residential buildings with 10+ units mixing bags and bins — DSNY is still rolling out containerization for these buildings, and complaints in this category are not yet accepted.
- Unknown-origin dumping in front of your property — file as Illegal Dumping, not Trash Disposal Complaint, to trigger a removal request.
How to Take Action
- Identify the right category first. The wrong category gets the wrong agency and your complaint dies. The four most relevant: Trash, Recycling, or Compost Disposal Complaint; Illegal Dumping; Dumpster Complaint; Litter Basket Complaint. Browse them at portal.311.nyc.gov/report-problems.
- Document the pattern. Take photos with timestamps. Note the exact address where waste is generated AND the address where it ends up. Note the days and times — “every Tuesday and Friday at 4 PM” is far stronger than “all the time.”
- File through the NYC311 app or website. You can also call 311 (or 212-NEW-YORK / 212-639-9675 from outside the city). Online filings give you a service request number to track the response.
- Track the request. Use the “Look Up Service Requests” tool on the 311 site to see when DSNY inspected and what action was taken. If it was closed without an inspection, you can refile with stronger documentation.
- Report illegal dumping separately for cash recovery. The DSNY Illegal Dumping Award Program returns a portion of fines to residents whose complaints lead to a conviction — but only if filed through the dedicated illegal dumping channel, not the general trash complaint.
Block-by-block strategy: what actually works
The single most effective complaint pattern HelpNewYork sees from readers: a chronic-pattern report filed by multiple neighbors within the same week, all referencing the same address and the same set-out time. DSNY’s inspection priority is data-driven — repeat complaints from a single block trigger faster site visits than scattered one-off reports across a neighborhood. If you and three neighbors file the same chronic-set-out complaint about the same building, you will almost certainly get an inspector within a week.
For mattress and refrigerator complaints, photograph the item the moment it appears and file before the next collection — DSNY’s response is to flag the item for non-collection until it is properly sealed or has the doors removed, which creates the enforcement pressure on the property owner.
Disclaimer
This article summarizes publicly available NYC311 and DSNY guidance and is intended as general information, not legal advice. Specific enforcement outcomes depend on the inspector’s findings and the property’s compliance history. Contact 311 or DSNY directly for situations involving disputes between tenants and landlords, or any case where you believe you are being targeted with retaliatory complaints.
HelpNewYork is here to help you navigate this. If your block has a chronic dumping problem and 311 isn’t moving fast enough, write to us — we publish reader-flagged patterns and keep public pressure on the agencies that owe you a response.
