NYC Heat Law: Requirements for Winter Heating (2025-2026)
Go Back To Previous PageThe NYC heating season runs from October 1 through May 31. During those months, landlords are legally required to keep apartments and hot water at
specific minimum temperatures, and the requirements are more precise than most tenants realize — there’s a daytime rule, a separate nighttime rule, and a year-round hot water rule that most articles skip entirely. Here’s exactly what the law requires, what happens if it’s violated, and what a rent-stabilized tenant can do that a market-rate tenant can’t.
NYC Heat Law Requirements (2025-2026 Heat Season)
The 40-60 word answer: From October 1 to May 31, if it’s below 55°F outside between 6 AM and 10 PM, your apartment must be at least 68°F. Between 10 PM and 6 AM, it must be at least 62°F no matter how cold it is outside. Hot water must be at least 120°F year-round, every day, without exception.
| Rule | Hours | Outdoor Trigger | Required Indoor Temp |
|---|---|---|---|
| Daytime heat | 6:00 AM – 10:00 PM | Outside below 55°F | 68°F minimum |
| Nighttime heat | 10:00 PM – 6:00 AM | Any outdoor temp | 62°F minimum |
| Hot water | 24/7, year-round | N/A — no heat season limit | 120°F at the tap (110°F if fixture has an anti-scald valve) |
Two details most heat-law articles leave out: hot water isn’t seasonal — landlords owe it 365 days a year, not just during the October-May heat season. And if a shower or tub has an anti-scald valve capping output, the minimum drops to 110°F for that fixture specifically, per NY State’s own guidance on the rule.
Why NYC Heat Laws Exist
New York City heat laws guarantee tenants the right to sufficient heating as a fundamental necessity of life. Without proper heating, an apartment can be deemed uninhabitable, and it’s part of what’s called the “warranty of habitability” that every NYC landlord owes every tenant, regardless of what the lease says.
Therefore, inNew York City, tenants have the explicit right to a sufficiently heated apartment during winter, enforced by the Department of Housing Preservation and Development (HPD).
Landlords cannot violate tenants’ protected rights, including the right to heating and hot water. Heat complaints remain one of the most common calls to 311 every winter, and enforcement is real: violations carry daily fines (details below), which are usually enough to get a landlord to act.

Rent-Stabilized Tenants Have an Extra Remedy Market-Rate Tenants Don’t
The 40-60 word answer: Market-rate tenants can call 311 and, if needed, sue in Housing Court. Rent-stabilized tenants have an additional option: filing DHCR Form HHW-1 (“Tenant Application for Rent Reduction”) for lack of heat or hot water. If DHCR rules in the tenant’s favor, it can order an actual rent reduction — not just a fine against the landlord.
Filing an HHW-1 requires an accompanying report from a city agency, typically an HPD violation from a 311 complaint, so the two remedies work together rather than as alternatives. If you’re not sure whether your unit is rent-stabilized, that’s worth confirming first since it changes your options here.
What Can You Do If Your Landlord Has Violated NYC Heat Laws?
- Notify the Landlord in Writing
- File a Complaint or Call 311
- Rent-Stabilized? File DHCR Form HHW-1
- Commence a Legal HP Proceeding
- Withhold Rent as a Last Resort
1. Notify the Landlord in Writing
Before escalating, notify your landlord. You can do this by calling, emailing, or writing a letter. Your lease or building rules should specify the procedures for filing a maintenance request. Keep a copy of all written correspondence for your records.
2. File a Complaint or Call 311
If your apartment has no heat or hot water, you can file a complaint online with the city or call 311 to report the conditions to HPD’s Central Complaint Bureau. This routes an inspector to the building and, if the violation is confirmed, triggers the fine schedule below.
3. Rent-Stabilized? File DHCR Form HHW-1
Once you have an HPD violation on record, rent-stabilized tenants can file DHCR’s HHW-1 form requesting a rent reduction for the period heat or hot water was inadequate. This is in addition to, not instead of, the HPD complaint.
4. Commence an HP Legal Proceeding If Your Apartment Lacks Heat
If all else fails, you can initiate a legal proceeding in housing court against your landlord, known as an “HP proceeding.” Tenants bring this type of case to compel landlords to make repairs, correct existing building violations, or address other issues with the landlord or building.
At Housing Court, the clerk will help you fill out an “Order to Show Cause” directing the correction of violations. In it, you’ll detail the lack of heat and can include any other repair needs in the apartment or common areas.
Upon filing, you can request an HPD inspection, though you can also request one after the initial court appearance to secure a faster court date. If you can’t afford the filing fee, you can apply to proceed as a poor person; if approved, you can bring your case against the landlord at no additional cost.
5. Withhold Rent as a Last Resort
Tenants can legally withhold rent during a serious heat outage, but should proceed with caution. If you withhold rent, your landlord may sue for nonpayment; you can then file a counterclaim that the landlord broke the warranty of habitability, and the court may order a rent abatement.
Since the exact abatement amount is never guaranteed in advance, be prepared to pay the full rent as a worst-case scenario, and only withhold what you can set aside until the court decides. Tenants who can’t pay rent, even after a court-ordered abatement, risk eviction for nonpayment — which is why most tenants find 311 and, where applicable, an HHW-1 filing the lower-risk path.
What Fines Do Landlords Face for Heat Violations?
The 40-60 word answer: HPD fines are tiered: roughly $250-$500 per day for a first heat violation, and $500-$1,000 per day for a repeat violation at the same building.
Landlords who fix the problem within 24 hours and pay within 10 days can settle for a flat $250. Tampering with heat systems can result in a separate Housing Court penalty starting at $1,000, plus $25/day.
| Violation Type | Fine |
|---|---|
| First heat/hot water violation | ~$250 – $500/day |
| Subsequent violation, same building | ~$500 – $1,000/day |
| Fixed within 24 hrs, paid within 10 days | Flat $250 settlement |
| Tampering with heat/hot water systems | Housing Court penalty, $1,000 + $25/day minimum |
New York City imposes these daily fines to make noncompliance expensive fast, which is why most landlords respond quickly once a 311 complaint results in a confirmed HPD violation.
What If You Have Heat but It’s Still Too Cold?
Some tenants find 68°F too cold and consider a space heater. If you do, observe basic fire safety: never place a space heater near flammable materials like curtains, rugs, or furniture; keep it on a stable, flat surface to prevent tipping; and plug it directly into a dedicated outlet rather than a power strip. Space heaters also draw significant electricity, which shows up on your utility bill.
What Can You Do If You Have Too Much Heat In Your Apartment?
Balancing heat across differently sized units on multiple floors is genuinely hard in older buildings, many of which don’t let tenants control heat individually—a common cause of overheated units.
Tenants can install a thermostatic radiator valve on old radiators to regulate output; it costs a few hundred dollars, and landlords may not fund it.
As a last resort, opening a window is the practical fix.
FAQ
Does the NYC heat law apply to co-ops and condos?
The Housing Maintenance Code’s heat and hot water rules apply to residential rental units. Co-op and condo owner-occupants aren’t tenants under a lease, so the specific HPD complaint process is generally for renters — though co-op/condo boards still have their own obligations under proprietary leases and bylaws.
Is heat required on weekends and holidays?
Yes. The heat law applies every day of the heat season, including weekends and holidays, with no exceptions for landlord staffing.
What if my landlord says they can’t afford to fix the boiler right now?
That isn’t a legal defense. HPD violations and fines accrue regardless of a landlord’s stated financial situation, and a broken boiler serving multiple units is typically treated as an emergency HPD will prioritize.
Does hot water have a season, as heat does?
No. Heat is only required during the October 1– May 31 season; hot water at 120°F (110°F behind an anti-scald valve) is required 365 days a year.
NYC Heat Laws Bottom Line
New York City winters are frigid, and the law doesn’t leave heat to a landlord’s discretion.
If your apartment isn’t warm enough during the heating season, or hot water isn’t 120°F any day of the year, document it, call 311, and know that rent-stabilized tenants have the added HHW-1 rent-reduction option.
Withholding rent should stay a last resort, since fines and DHCR remedies are usually faster and lower-risk than a Housing Court standoff.
