Who this helps: NYC tenants in any of the five boroughs whose apartments are too cold, whose hot water has been intermittent, or whose landlord is hinting that “heat season is over.” It isn’t. Not yet.
Spring in New York is deceptive. Daytime temperatures climb into the 60s, the windows come open — and then the overnight low drops to 38 degrees, the radiator stays cold, and the bathroom faucet runs lukewarm at best. Many tenants assume that once the calendar flips to April, their landlord no longer has to provide heat. That is wrong, and it is a misunderstanding that costs renters their comfort and their legal leverage every single year.
Heat season in New York City runs from October 1 through May 31, according to the NYC Department of Housing Preservation and Development (HPD). That gives you roughly six more weeks of legally required heat as of this article’s publication date. Here is exactly how to use that window if your apartment is not warm enough.
What the Law Actually Requires
HPD’s heat and hot water rules are specific and enforceable. Per the official HPD guidance:
- Daytime (6 AM to 10 PM): When the outside temperature falls below 55°F, the indoor temperature must be at least 68°F.
- Nighttime (10 PM to 6 AM): The indoor temperature must be at least 62°F, regardless of outside temperature.
- Hot water: Must be provided 24 hours a day, 365 days a year, at a minimum of 120°F. There is no “hot water season” — this is a year-round requirement.
If your landlord is not meeting these standards, HPD considers the issue an emergency-class violation requiring a 24-hour response window for inspection.
How to File a 311 Heat Complaint That Gets a Real Response
You have three filing options. All of them work. The fastest is the phone.
- Call 311. Say “heat complaint” or “hot water complaint.” Have your address, apartment number, and a contact phone number ready.
- File online at the official NYC311 portal — search “Heat or Hot Water Complaint in a Residential Building.”
- Use the NYC311 mobile app, available for iOS and Android.
Before you file, do these three things — they dramatically increase your chances of a violation being issued:
- Take a photo of an indoor thermometer showing the temperature, with a timestamp if possible.
- Note the outside temperature at the moment of the complaint (a screenshot of your weather app works).
- Document any prior contact with your landlord or super — texts, voicemails, emails. HPD asks whether you tried to resolve it directly first.
What Happens After You File
According to HPD’s posted complaint process, once you file a 311 heat or hot water complaint, the agency attempts to notify the building owner or managing agent and may also call the tenant back to verify that service has been restored. If service is still out, HPD dispatches an inspector to the building to verify the complaint and issue the appropriate violation.
HPD charges building owners a $200 inspection fee for all inspections after the first two if those inspections result in a heat violation in the same heat season, or a hot water violation within the same calendar year. If conditions are not corrected, HPD may step in through its Emergency Repair Program — contracting with private companies to restore heat and hot water and billing the building owner.
Spring Heat Complaints Have Special Urgency
Late-season complaints matter more than people realize. Building owners sometimes try to wind down boiler operations early to save fuel costs, especially after a string of warm days. If your radiator goes cold the third week of April and you do not file, you have no record of the violation should you need it later — for a rent reduction case, an HP action in housing court, or a complaint to the New York State Attorney General’s Tenant Protection Unit.
Where Heat Complaints Are Trending This Spring
Based on patterns reflected in the publicly available NYC Open Data 311 datasets, heat and hot water complaints typically run highest in older multi-family housing stock — meaning parts of the Bronx, Washington Heights, Inwood, Bedford-Stuyvesant, Crown Heights, and Sunset Park tend to generate the highest volumes during cold snaps. If you live in any of these neighborhoods, you are not imagining it. You are part of a citywide pattern, and your complaint adds to the data the city uses to prioritize enforcement.
How to Take Action
- File a 311 heat complaint: Call 311, file at portal.311.nyc.gov, or use the NYC311 app.
- HPD Heat and Hot Water info page: nyc.gov/site/hpd/services-and-information/heat-and-hot-water-information.page
- Free legal help for tenants: Call the NYC Tenant Helpline at 311 and say “tenant helpline,” or contact the Met Council on Housing Tenants’ Rights Hotline at 212-979-0611 (Mondays and Wednesdays 1:30 PM–8 PM, Tuesdays 5:30–8 PM, Fridays 1:30–5 PM).
- Look up your building’s HPD violation history at hpdonline.nyc.gov before signing a renewal lease — recurring heat violations are a red flag.
- If conditions are dangerous (no heat with vulnerable residents, no hot water for more than 48 hours), follow up your 311 complaint with a call to your local City Council member’s housing office.
What If You’re a Co-op or Condo Owner?
The same heat and hot water requirements apply. Your complaint should still go through 311, and HPD will inspect — but enforcement runs through your building’s board and managing agent rather than a traditional landlord. Document everything in writing through your managing agent and CC the board.
The Bottom Line
You have until May 31, 2026 to file heat complaints under the current heat season. After that, the legal threshold shifts and your complaints will fall under hot water and habitability rules rather than heat-specific enforcement. If your apartment has been cold this spring and you have not filed, file now. The data matters. Your record matters. And HPD does respond — but only to the complaints they receive.
