What to Do When Your NYC Apartment Has No Heat
Meta description: Learn NYC’s legal heat requirements, how to report a cold apartment, what to document, and how to stay safe while your landlord makes repairs.
A cold apartment in New York City is more than an inconvenience: building owners must provide heat during the city’s heating season. Knowing the temperature standards, how to contact your landlord, and when to report a violation can help residents respond quickly. The right steps also depend on whether the problem affects one apartment or the entire building, and whether there is an immediate safety hazard.
Know NYC’s Legal Heat Requirements
New York City’s official heating season runs from October 1 through May 31. During this period, residential building owners are required to provide heat when outdoor temperatures and the time of day trigger the city’s standards.
- Daytime, 6 a.m. to 10 p.m.: If the outdoor temperature falls below 55°F, the indoor temperature must be at least 68°F.
- Nighttime, 10 p.m. to 6 a.m.: The indoor temperature must be at least 62°F, regardless of the outdoor temperature.
These standards apply to residential buildings, including rental apartments. The daytime rule does not require the same indoor temperature during every weather condition: the outdoor temperature must be below 55°F. The nighttime minimum is different because it applies regardless of outdoor temperature during heating season.
New York City also requires building owners to provide hot water year-round at a minimum temperature of 120°F. Although hot water is a separate requirement from apartment heat, a simultaneous loss of both may point to a broader boiler or building-system problem.
Residents can check the city’s current guidance on NYC Department of Housing Preservation and Development (HPD) heat and hot water. The official rules, rather than a landlord’s preferred thermostat setting, determine the minimum requirements.
What to Do First When the Apartment Is Cold
Start by checking the indoor temperature with a reliable thermometer. Take readings in a commonly used room, away from a window, exterior door, radiator, or direct sunlight. Note the time and the outdoor conditions. A simple thermometer reading is useful when describing the issue to the landlord or a city agency.
Then contact the landlord, property manager, or building superintendent promptly. Use a method that creates a record, such as email, a tenant portal, or text message. Include the apartment number, when the heat stopped or became inadequate, the temperature readings, and whether the problem affects other rooms. Ask when repairs are expected.
If there is no response, the heat is not restored promptly, or the indoor temperature appears to fall below the legal minimum, report the problem to 311. Residents can call 311 or submit a report through the city’s website or 311 app. For a report about a lack of heat, provide the building address and apartment number and explain what has happened.
Calling the landlord first is practical, but it is not a prerequisite to contacting 311. A resident who cannot reach management, or whose household faces an urgent cold-weather risk, can report the condition directly.
Report a No-Heat Problem to 311
When a resident reports inadequate heat, 311 can route the complaint to HPD. HPD may attempt to contact the owner and, depending on the circumstances, send an inspector. If an inspector finds a violation, the agency can issue a notice requiring correction. The inspection and enforcement process may take time, so residents should keep communicating with management and preserve their own records.
After making a complaint, save the 311 service-request number. Residents can use it to check the status of the request and to follow up if the condition continues. If the heat is still out, the temperature drops further, or a new detail changes the situation, contact 311 again and refer to the earlier request.
A 311 report is not a substitute for emergency services. Call 911 if someone is in immediate danger, has severe symptoms of cold exposure, or faces another life-threatening emergency. For a suspected gas leak or carbon monoxide emergency, leave the area and follow the emergency guidance below.
Document the Conditions and Keep a Clear Record
Good documentation can make it easier to explain the problem to building management, HPD, a tenant-support organization, or a lawyer. Keep a simple log with the date, time, indoor temperature, outdoor conditions, and the steps taken to request repairs. If the heat returns and fails again, record each interruption rather than treating the issue as a single event.
- Save emails, texts, maintenance requests, and written responses from the landlord or superintendent.
- Record thermometer readings and photograph the thermometer where practical.
- Note which rooms are cold and whether radiators, vents, or other heating equipment appear to be working.
- Keep the 311 complaint number and any inspection or agency communications.
- Write down the dates and times of phone calls, along with the name or role of the person contacted.
Photos and videos can help show a condition, but they do not replace an accurate thermometer reading or a city inspection. Residents should not dismantle a radiator, boiler component, or other building equipment to prove that it is not working.
Stay Safe While Waiting for Repairs
Use only a portable space heater that is in good condition and certified by a recognized testing organization, such as UL. Place it on a stable, level surface, keep it at least three feet from bedding, curtains, furniture, clothing, and other combustible materials, and plug it directly into a wall outlet. Do not leave it running unattended or while sleeping, and follow the manufacturer’s instructions.
Never use a gas stove, oven, charcoal grill, camping stove, or outdoor heater to warm an apartment. These devices can cause fires or produce deadly carbon monoxide. Do not run a generator indoors, in a hallway, or near windows or air intakes. Keep smoke and carbon monoxide alarms operational, and do not block building exits or corridors with heaters or other equipment.
Layer clothing and use blankets while arranging repairs, but do not let temporary measures delay reporting the problem. Older adults, infants, people with certain medical conditions, and anyone who cannot keep warm may need to relocate temporarily to a heated place. If a person becomes confused, unusually drowsy, weak, or difficult to warm, seek urgent medical help.
For a suspected gas odor or a carbon monoxide alarm, do not try to locate the source or switch electrical devices on or off. Leave the building or affected area, move to fresh air, and call 911 from a safe location. Follow instructions from emergency responders and the utility company.
Understand Common Causes Without Taking Repair Risks
No heat can result from a building-wide boiler failure, a malfunctioning thermostat, a problem with a radiator or heating loop, or a localized issue in one apartment. If several neighbors have the same problem, that information may help management identify a building-system failure. If only one room or apartment is affected, there may be a local distribution or control problem.
Residents can safely note whether radiators are cold, whether heating pipes feel warm, and whether neighboring apartments are also affected. They should not bleed a radiator, remove covers, adjust boiler controls, or attempt electrical or plumbing repairs unless specifically authorized and qualified. Changes to shared systems can create hazards or damage and may affect other apartments.
Some buildings use systems that make noise or heat unevenly, but noise alone does not establish whether a legal heat violation exists. The relevant question is whether the apartment meets the required indoor temperature under the applicable time and outdoor-temperature conditions. Document the actual conditions and let qualified building personnel inspect the equipment.
What Tenants Can Do if the Landlord Does Not Act
If management does not restore heat, residents can continue reporting the condition to 311 and keep records of every contact. A tenant may also contact a local tenant organization or a lawyer for guidance about available options. HPD’s tenant resources provide information about housing conditions and city services.
In some situations, tenants can ask the Housing Court to order a landlord to make repairs through an HP proceeding, sometimes called an HP action. The process and the evidence needed depend on the circumstances. Residents should consult the court’s official information or obtain legal advice before filing, especially if there are other housing or lease issues involved.
Tenants should be cautious about withholding rent, arranging repairs and deducting the cost, or breaking a lease without advice. Those steps can carry legal or financial risks, and the right response depends on the facts. A tenant can seek help from a qualified attorney or a nonprofit tenant-services organization before taking such action.
Residents in rent-regulated apartments can also ask the New York State Division of Housing and Community Renewal (DHCR) about rights and complaint procedures that may apply to their tenancy. DHCR’s role is distinct from HPD’s city enforcement role, so the appropriate agency can depend on the issue.
When the Problem May Be a Utility Outage
If the apartment uses electric heat or building equipment that depends on electricity, check whether neighbors or common areas have also lost power. Report an outage to the electric utility and follow its safety instructions. In New York City, residents can find outage information and report a problem through Con Edison or their service provider.
A utility problem does not make an unsafe workaround acceptable. Do not use a stove, grill, or generator inside to replace electric heat. If the apartment becomes dangerously cold, contact 311 for the housing condition and seek a safer heated location. Call 911 for an immediate medical or fire emergency.
Quick Checklist for a No-Heat Apartment
- Measure and record the indoor temperature and the time of the reading.
- Notify the landlord, property manager, or superintendent in writing and request repairs.
- Call 311 or submit a heat complaint if the problem persists, management cannot be reached, or conditions appear to violate city requirements.
- Save the 311 request number, messages, photos, and a dated temperature log.
- Use a portable heater only according to its safety instructions; never heat the apartment with an oven, grill, or generator.
- Seek emergency help for signs of serious cold exposure, a gas leak, or suspected carbon monoxide.
For accurate, current instructions, residents can review HPD’s heat and hot water information and contact 311. A prompt written report, reliable temperature records, and safe temporary measures help residents address a no-heat problem while city agencies and building staff work toward a repair.
