Water leak in your apartment: who is responsible?

NYC building owners must repair leaks from the roof, pipes or the unit upstairs. Who pays for your damaged things, how to report a leak to 311, and mold rules.

7 min read · Updated

In a New York City apartment building, the owner is responsible for stopping and repairing a leak, whether it comes from the roof, a building pipe or the apartment upstairs. Who pays for your damaged belongings is a separate question: usually your renters insurance first, then whoever was negligent, whether that is the landlord or the neighbor.

New York's Multiple Dwelling Law says every multiple dwelling, “including its roof,” must be kept in good repair, and the owner is responsible for that. A tenant is also liable if a violation is caused by their own willful act or negligence, or that of their household or guests. That split drives most leak disputes.

Who is responsible for what

Typical responsibility by leak source (general rule; facts and lease terms matter)
Fix the sourceRepair your ceiling/wallsPay for your belongings
Roof or facade leakOwnerOwnerYour insurer; owner if negligent
Building pipe, riser or boiler lineOwnerOwnerYour insurer; owner if negligent
Upstairs neighbor's overflowing tub or applianceNeighbor stops it; owner repairs building partsOwnerYour insurer; neighbor if negligent
Leak you caused (left a faucet running)Owner repairs buildingOwner, but may seek costs from youYou (your insurer)
Flood or sewer backupOwnerOwnerOften excluded from standard renters policies

The building itself (ceilings, walls, floors, pipes, the roof) is the owner's to repair regardless of who caused the leak. Liability for damage to your property usually turns on negligence: did someone fail to act reasonably? A landlord who ignored repeated reports of a dripping roof is in a very different position from one hit by a pipe that burst without warning.

Your belongings: renters insurance vs. a claim

New York's Department of Financial Services is direct about this: the landlord's insurance “will not protect you or your belongings as a renter.” Standard renters policies typically cover water from plumbing failure, appliance failure, sprinklers and other accidental discharges. A standard policy does not cover floods, and sewer and drain backups are coverage you may need to add. DFS also notes one exception to the landlord-doesn't-pay rule: when the landlord knew of a hazardous condition, failed to fix it in a reasonable time, and your property was damaged as a result.

  • File with your own insurer first. It is usually faster. If the leak was someone else's fault, your insurer may pursue them to recover what it paid you.
  • Living expenses. If your apartment becomes unlivable during repairs, check whether your policy pays for temporary housing; DFS says renters policies may cover it.
  • No insurance? Send a written demand to whoever you believe was negligent (the landlord, the neighbor or both) with photos and an itemized list of losses. If they refuse, small claims court is a common next step.

See our renters insurance guide for what to buy before the next leak.

If the landlord doesn't fix it

Write down the date you reported the leak and keep every message. If repairs don't happen, file a complaint through 311 (online, app or phone). HPD can inspect and issue a violation. Most water-leak violations are written as Class B (hazardous), but a leak can be Class C, the immediately hazardous class, depending on what the inspector finds.

Other options, depending on your situation:

  • HP action. Ask a Housing Court judge to order the repairs. See HP actions explained.
  • Rent reduction for stabilized tenants. NYS Homes and Community Renewal lists “water leak (cascading water, soaking electrical fixtures)” among the emergency conditions it processes first. File Form RA-81 for your apartment or RA-84 for building-wide problems. A rent reduction for stabilized tenants is generally the most recent lease guideline increase, effective from the first of the month after HCR serves the complaint on the owner.
  • Warranty of habitability. Every New York residential lease includes a promise that the apartment is fit to live in. A court can reduce rent for the time a serious leak made part of the apartment unusable. Read can I withhold rent before holding back any payment.

After the water stops: watch for mold

Mold needs moisture to grow, so wet drywall and ceilings are a risk. Under Local Law 55, owners of buildings with three or more units must fix the underlying moisture and remediate mold with safe work practices. HPD classes mold violations by size:

Mold in a roomClassTime to correct
Under 10 sq ftA90 days
10 to 29 sq ftB30 days
30 sq ft or moreC21 days
Source: NYC HPD, Indoor Allergen Hazards

In buildings with 10 or more units, mold over 10 square feet must be assessed and removed by separate, NYS-licensed mold professionals. Painting over a stain is not a repair. More in mold in your NYC apartment.

If you are the upstairs neighbor

Shut off the water at the fixture if you can, tell the super right away, and notify your own insurer. If your appliance, tub or negligence caused the leak, you can be liable for damage to the apartment below. Ask your insurer whether the liability part of your renters policy applies.

This is general information, not legal advice. Who pays for damage depends on the facts, your lease and your insurance policy.

Fact-checked October 12, 2026

Independent fact-check 2026-10-12. MDL §78 (owner keeps building "including its roof" in good repair; tenant liable for own willful act or negligence), RPL §235-b and GOL §5-321 ("void as against public policy and wholly unenforceable") read on nysenate.gov. DFS renters page confirms landlord policy does not cover tenant belongings, the prior-hazard exception, water-discharge coverage, flood exclusion and sewer/drain backup add-on. HPD ABCs of Housing confirms no advance notice for leaking pipes/roofs/dangerous ceilings and the Underlying Conditions Program. HPD allergen page confirms mold classes and 10+ unit licensed-assessor rule. HCR FS-14 (11/2023) confirms emergency list and reduction terms. Violation table re-queried: the original LEAK filter also matched 3,265 rat violations whose text mentions fixing leaks, so it now counts descriptions containing "WATER LEAK" only; an unsupported claim that roof leaks are often Class C was removed.
