1. NYC Heat Law Requirements during Heat Season
The heating requirement depends on the time of day and, during daytime hours, the outdoor temperature. A warm radiator does not establish compliance if the apartment remains below the applicable minimum.
Daytime and Overnight Temperature Rules
The Housing Maintenance Code establishes these requirements during heat season:
| Time | Outdoor Temperature Condition | Minimum Indoor Temperature |
|---|---|---|
| 6 a.m. .o 10 p.m. | Below 55°F | 68°F |
| 10 p.m. .o 6 a.m. | Any outdoor temperature | 62°F |
6 a.m. .o 10 p.m.
- Outdoor Temperature ConditionBelow 55°F
- Minimum Indoor Temperature68°F
10 p.m. .o 6 a.m.
- Outdoor Temperature ConditionAny outdoor temperature
- Minimum Indoor Temperature62°F
The daytime trigger is strictly below 55°F. At night, the owner must maintain the minimum indoor temperature even when the weather is mild.
These are city requirements. Older summaries using a 40°F outdoor threshold and a 55°F indoor minimum overnight do not reflect the current rule.
Heating and Hot Water Have Different Schedules
Heat season in NYC runs from October 1 through May 31. Hot water obligations continue year-round, so the end of heating season does not excuse a hot water outage.
Temperature requirements are one part of landlord-tenant law. A separate habitability claim examines whether conditions interfere with safe, livable housing.
2. Check the Temperature and Keep a Useful Record
Measure the air temperature in the affected room rather than relying on how the heating equipment feels. Record when you took the reading and the outdoor conditions so the applicable standard is clear.
What to Include in Your Heating Log
Use a room thermometer according to its instructions. Avoid placing it directly beside a radiator, portable heater, or open window, which may distort the reading.
Keep a simple record of:
- The date, time, room, and indoor temperature.
- Outdoor temperature information for daytime readings.
- When heating stops and resumes.
- Repair requests and management’s responses.
- Complaint numbers and inspection results.
Photographs of the thermometer can supplement the log. Keep original messages and images as part of your evidence preservation. Your records help establish the history of the problem, but they do not replace an HPD inspection.
Why Time of Day Matters
A 65°F indoor reading is below the daytime minimum when the outdoor temperature is under 55°F. The same indoor reading exceeds the overnight minimum.
That difference matters when describing an outage. “The apartment was cold all weekend” is less useful than readings showing which rooms were cold, when, and for how long.
3. How to Report No Heat in NYC
Notify your landlord or managing agent about inadequate heating. If the owner does not respond or the problem remains unresolved, file a complaint by calling 311 or using its online or mobile service.
Give Management and 311 Specific Information
Include your address, apartment number, and the time the problem began. Explain whether heating is absent, insufficient, or repeatedly interrupted. Provide temperature readings if you have them.
Send a written repair request when practical and save a copy. If management promises a repair, record the promised date and whether adequate heating returns.
Keep your 311 service-request number. You do not need to postpone reporting an unresolved problem while waiting indefinitely for management to act.
Help HPD Verify the Condition
The Department of Housing Preservation and Development, or HPD, may contact you to ask whether heating has returned. Explain whether service is stable or continues to fail.
Make inspection access possible. If an inspector cannot enter your apartment, they may attempt another apartment in the building. Access to the affected unit helps HPD assess the condition you reported.
4. What HPD Can Establish after Your Complaint
A complaint starts the agency response; it does not automatically establish a violation or guarantee a repair. HPD attempts to notify the owner and may contact you before attempting an inspection.
The Inspection Captures Conditions at That Moment
During a daytime inspection, the inspector checks both indoor and outdoor temperatures. Overnight, the indoor minimum applies regardless of the outdoor reading.
Heating sometimes returns before an inspector arrives. A compliant reading then does not establish what happened earlier. Continue documenting recurring interruptions and report them accurately when they occur.
Use HPD Online to review complaint information and issued violations. If a complaint closes but heating fails again, preserve the earlier complaint number alongside the new outage records.
Violations, Enforcement, and Emergency Repairs
HPD may issue violations and pursue enforcement against the owner. In qualifying circumstances, its Emergency Repair Program may arrange restoration of essential services and charge the owner.
Emergency repairs have additional criteria, so a heating violation does not automatically trigger a city-arranged repair. Civil penalties imposed on an owner also differ from rent relief a tenant may seek.
5. When Heating Problems Require Court or Rent Relief
If inadequate heating persists, consider whether you need an order restoring service, financial relief, or both. These remedies involve different procedures and evidence.
An HP Proceeding Can Seek Restoration of Heat
A tenant may start an HP proceeding in Housing Court after notifying the landlord about conditions that remain uncorrected. An existing HPD violation is not necessarily required.
File in the county where the apartment is located. Identify the conditions needing correction and bring the owner’s or managing agent’s information. Follow the signed court order’s instructions for serving papers and meeting deadlines.
For repeated outages or an ignored repair order, an attorney handling real estate litigation can review the evidence and available enforcement steps. Bring your lease, heating log, repair requests, and complaint history.
Rent Relief Is Not Automatic
New York State’s warranty of habitability protects residential tenants against conditions that undermine safe, livable housing. Inadequate heating may support a rent abatement, depending on its severity, duration, and the evidence.
Tenants in rent-regulated apartments may also qualify for a DHCR rent-reduction remedy based on reduced services. A 311 complaint alone does not establish either form of relief.
Withholding rent can lead to a nonpayment case. Before changing payments, obtain advice about the available remedy and keep the disputed funds available. If you receive court papers, respond by the applicable deadline.
6. Frequently Asked Questions
Yes. HPD permits anonymous complaints. In that situation, the inspector selects an apartment to attempt to inspect. Providing contact details helps the agency reach you and inspect the affected unit.
HPD’s complaint guidance does not impose a general 24-hour waiting period on tenants. Notify the landlord and report an unresolved condition. Deadlines governing an owner’s correction of a violation are separate.
Never use a gas stove or oven to heat your home because of carbon monoxide and fire risks. Temporary heating measures do not eliminate the owner’s obligation to meet the applicable temperature requirements.
