The NYC warranty of habitability is an automatic legal guarantee, written into every residential tenancy in New York, that your apartment and its shared spaces are safe, livable, and free from conditions that threaten your health or safety. It comes from New York Real Property Law Section 235-b and applies whether your lease says so or not.1New York State Senate. New York Real Property Law 235-B – Warranty of Habitability If your landlord fails to meet it, you have concrete ways to force repairs and reduce what you owe.
What Conditions the Warranty Covers
The statute does not list every problem. It sets a standard: your apartment and the building’s common areas must be fit for human habitation and free from conditions dangerous or harmful to your life, health, or safety.1New York State Senate. New York Real Property Law 235-B – Warranty of Habitability Courts ask whether a condition meaningfully interfered with your ability to live there safely and comfortably.
In practice, that covers structural problems with roofs, floors, walls, and windows, so the apartment stays weather-tight and secure. It covers broken plumbing and faulty wiring. Pest infestations of mice, rats, or roaches are the landlord’s responsibility, not yours. Visible mold, broken entry-door locks, and inadequate lighting in common areas all fall inside the warranty.
Heat and Hot Water Standards
NYC sets specific numbers for heat during heat season, which runs October 1 through May 31. Between 6:00 a.m. and 10:00 p.m., if it’s under 55°F outside, indoor temperature must be at least 68°F. Between 10:00 p.m. and 6:00 a.m., indoor temperature must reach at least 62°F regardless of the outdoor reading.2NYC Housing Preservation and Development. Heat and Hot Water Information Every hour a building sits below those numbers is a violation.
Hot water is required all year, at every faucet, 24 hours a day, at a minimum of 120°F. Losing hot water for a single day in July is a violation you can report the same day.
Lead Paint in Older Buildings
Most NYC housing predates 1960, which puts lead paint squarely in the picture. Under NYC health regulations, landlords of pre-1960 rental buildings must address lead paint hazards when a child under six lives in the unit or regularly spends ten or more hours a week there. Buildings built between 1960 and 1978 can also fall under these rules in some circumstances. The landlord must inspect for peeling or deteriorating paint, safely repair hazards, and keep records.3NYC Health. Lead Poisoning – Information for Residential Building Owners
A separate federal rule applies to virtually all pre-1978 housing. Before you sign, the landlord must disclose any known lead paint or hazards, hand over any inspection reports they have, and give you the EPA pamphlet “Protect Your Family From Lead in Your Home.” The lease itself must include a lead warning statement.4U.S. Environmental Protection Agency. Lead-Based Paint Disclosure Rule Landlords who skip these steps face federal penalties, and tenants who never received the disclosure may have additional remedies.
Who Is Covered
The warranty covers essentially every residential tenant in New York. Written lease, oral agreement, month-to-month arrangement, public housing, rent-stabilized, rent-controlled: all in.1New York State Senate. New York Real Property Law 235-B – Warranty of Habitability
Any lease clause that tries to waive or limit these rights is void as a matter of public policy.1New York State Senate. New York Real Property Law 235-B – Warranty of Habitability “Accepts the premises as-is” and “waives all claims related to condition” language in the fine print is legally worthless. A court will disregard it. You have not signed anything away.
Start With a 311 Complaint
Before Housing Court, most tenants should file a complaint with the city. NYC’s 311 system routes maintenance complaints to the Department of Housing Preservation and Development (HPD). You can call 311, use the website, or use the app. Try to notify your landlord or building manager first, because HPD expects that.5NYC.gov. Apartment Maintenance Complaint
Once you file, HPD contacts the managing agent to warn that a violation may issue if the problem isn’t corrected. HPD also tries to reach you to confirm whether the issue was fixed. If it wasn’t, or HPD can’t reach you, an inspector is dispatched without warning to the landlord.5NYC.gov. Apartment Maintenance Complaint
HPD violations come in three classes. Class A is non-hazardous, like minor peeling paint over a small area, with a longer correction window. Class B is hazardous, with a 30-day deadline. Class C is immediately hazardous — no heat, no hot water, lead paint hazards, vermin infestations — and must be corrected within 24 hours. A Class C violation on your record is powerful documentation if you end up in court.
Filing an HP Action in Housing Court
When violations sit uncorrected, you can file an HP proceeding in NYC Housing Court. It’s a case designed specifically to force repairs, and it’s set up so tenants can file without a lawyer.
You’ll need your landlord’s legal name and physical address (not a P.O. box), which you can find in HPD’s building registration or the city’s property records. Bring that information, a complete written list of the conditions you want addressed, and the filing fee of about $45 to the Housing Court clerk in your borough. If you can’t afford the fee, ask the clerk for a Poor Person’s Relief form. The clerk hands you three documents: a Request for HPD Inspection, a Verified Petition, and an Order to Show Cause.
Be exhaustive on the Request for HPD Inspection. Every problem gets its own line. If you leave something off, the inspector may not document it and the court’s order may not reach it. A judge reviews and signs the Order to Show Cause, which sets a hearing date and triggers an independent HPD inspection.
After the judge signs, you’re responsible for serving the landlord and HPD on the schedule and by the method the judge specifies, usually certified or first-class mail within a set number of days. Missing the deadline or using the wrong method can get your case dismissed, so use the court’s help center if you’re unsure.
Rent Abatements: What You Can Recover
When a court finds a breach of the warranty, the main financial remedy is a rent abatement. It isn’t a check from the landlord. It’s a percentage reduction of the rent you owed while the conditions existed, credited against what you owe.
Judges use a diminution-in-value approach: the gap between what the apartment was worth in good condition and what it was worth with the defects. The ranges below come from housing court decisions, not from any statute:
- Complete loss of essential services, like no heat in winter or no running water, can produce abatements of 50% or more of the monthly rent for the affected days, and courts have awarded up to 100% in extreme cases.
- Serious but partial problems, such as persistent pest infestations, chronic leaks causing mold, or broken bathroom fixtures, often land in the 15% to 40% range.
- Minor defects like a dripping faucet, cracked plaster, or a sticking window may yield 5% to 15%.
The judge has broad discretion, and documentation drives the outcome. A tenant with dated logs, timestamped photos, and copies of every 311 and HPD filing will do substantially better than one with a general story about a cold winter.
Building the Evidence That Wins
Start a written log the moment a problem appears. Dates, times, specific descriptions. “No heat” is useful. “No heat on January 14, indoor temperature 48°F at 7:00 a.m., outdoor temperature 22°F” is much more useful.
Take photos and video with timestamps on. Shoot the same conditions repeatedly over time to show the problem is ongoing rather than a one-day event. If you have a thermometer, photograph its reading with the time and date visible. For pests, photograph droppings, damage to food containers, and any dead insects or rodents.
Keep every communication with your landlord. Texts and emails create automatic records. Letters should go by certified mail with return receipt so you can prove delivery. Save your 311 complaint confirmations and any HPD inspection reports. All of this proves three things at once: the conditions existed, the landlord knew, and they persisted after notice.
Protection Against Retaliation
Real Property Law Section 223-b bars landlords from evicting or penalizing a tenant for filing a good-faith habitability complaint, contacting a government agency about code violations, or joining a tenant organization. If a landlord takes adverse action within a set window after you exercise those rights, courts can presume retaliation and put the burden on the landlord to show a legitimate reason.
These protections don’t make you immune from eviction for independent reasons. A landlord can still pursue eviction for nonpayment or for lease violations unrelated to the complaint. Timing matters, though. An eviction notice arriving shortly after an HP action will draw scrutiny, and the landlord will need to show the two are unrelated.
Constructive Eviction When Conditions Force You Out
Sometimes conditions get so bad that staying is impossible. When a landlord’s failure to maintain the premises effectively forces you to leave, the law calls it constructive eviction. If you can prove the apartment was genuinely uninhabitable and you left within a reasonable time after conditions became intolerable, you may be released from the remaining lease.
Timing is the pressure point. Courts expect tenants to leave promptly once conditions cross from bad to unlivable. Staying for months after a catastrophic problem develops undercuts the claim. There’s no bright-line rule, but the longer you wait, the weaker your case.
This is a serious step. If a court later decides the conditions didn’t justify leaving, you could owe the rest of the lease. Document exhaustively before you go, and consider consulting a housing attorney. The Housing Court help centers and organizations like Legal Aid can help at no cost.
Extra Option for Rent-Stabilized Tenants
If you’re in a rent-stabilized apartment, you have another route beyond Housing Court. You can file a complaint with the Division of Housing and Community Renewal (DHCR), which can issue a rent reduction order when services drop below the required level.6Homes and Community Renewal. Living Conditions and Essential Services A DHCR order lowers your legal regulated rent going forward until the landlord restores services and applies to have the rent returned to its prior level.
DHCR and Housing Court run in parallel. Some rent-stabilized tenants pursue both at once: an HP action to compel the repairs and a DHCR complaint to reduce the rent until those repairs actually happen. One remedy is about getting the work done. The other is about adjusting what you pay while you wait.
