Found a Leak After Closing: Can I Go After the Seller?

You have just moved in, and the first heavy rain brings a stain on the ceiling or water in the basement. The first reaction is often, “The seller must have known. I want them to pay!” In New York, whether you can go after the seller depends on what the seller said, what the seller did and what the contract says.

The Starting Point: Buyer Beware

New York has traditionally followed caveat emptor: a seller generally has no duty to volunteer information about the property’s condition, and the buyer is responsible for inspecting before buying. Mere silence usually is not fraud. But in the situations below, a buyer may have a claim.

Situation One: A False Disclosure Statement

Since March 20, 2024, sellers of one- to four-family homes must deliver a Property Condition Disclosure Statement (PCDS) before the buyer signs, including questions about roof leaks and basement water. Under Real Property Law §465, a seller who willfully fails to meet the disclosure requirements (for example, answering “no” while knowing about a leak) is liable for the buyer’s actual damages, in addition to other legal remedies.

Note that sellers answer based on actual knowledge and have no duty to investigate. Answering “unknown” truthfully generally is not a violation. Condo and co-op sellers do not complete a PCDS.

Situation Two: The Seller Actively Concealed the Problem

If the seller took active steps to hide a defect, such as painting over water stains, temporarily boarding up a leak or removing buckets before showings, the buyer may sue for fraud or fraudulent concealment. In the well-known “haunted house” case (Stambovsky v. Ackley, 169 A.D.2d 254 (1st Dep’t 1991)), a New York court also recognized that in special circumstances, a seller may be liable for exploiting facts that only the seller knew and the buyer could not reasonably discover.

But fraud claims are not easy. The buyer must prove a false statement or active concealment, the seller’s knowledge, the buyer’s justifiable reliance and damages. If the contract contains a specific disclaimer, for example a statement that the buyer is “not relying on any representations by the seller as to the physical condition,” proving reliance becomes much harder (Danann Realty Corp. v. Harris, 5 N.Y.2d 317 (1959)).

Situation Three: Do the Contract’s Promises “Survive”?

Many New York contracts have the seller represent that the plumbing, electrical and heating systems will be in working order at closing, and that the roof is free of leaks. But under New York’s merger doctrine, the contract generally merges into the deed at closing and its terms are extinguished, unless the contract expressly says a provision survives. So when you discover a leak after closing, the first question is whether the contract has a survival clause.

Situation Four: New Construction

For a new home bought from a builder, General Business Law §777-a provides a statutory implied warranty:

• 1 year for construction defects;
• 2 years for defects in the installation of plumbing, electrical, heating, cooling and ventilation systems;
• 6 years for material defects.

The buyer must give the builder written notice within the warranty period (and no later than 30 days after it expires). For new condos, look to the sponsor’s warranty in the offering plan.

Situation Five: Condos and Co-ops

In an apartment, the party responsible for a leak is often not the seller but the building or the neighbor upstairs. Check the co-op’s proprietary lease or the condo’s bylaws to see who repairs the roof, facade and risers. Contact the managing agent and your insurer.

Deadlines: Don’t Wait

• Fraud: six years from the fraud, or two years from when it was or should have been discovered, whichever is later (CPLR 213(8));
• Breach of contract: generally six years (CPLR 213(2));
• New home warranty: subject to the warranty and notice periods above.

What to Do as Soon as You Find a Leak

1. Stop the damage. Call a plumber or roofer and keep the invoices;
2. Document everything. Take photos and video, and note the date and circumstances;
3. Preserve evidence. Avoid tearing out and repairing every trace before the other side has a chance to inspect;
4. Gather documents: the PCDS, inspection report, listing photos, emails and the contract;
5. Check the records. Your attorney can search Department of Buildings permits for past roof or waterproofing work;
6. Notify your insurer. Homeowners policies usually cover “sudden and accidental” water damage, not long-term seepage or wear and tear;
7. Consult an attorney promptly, and have the attorney notify the seller in writing. For smaller amounts, small claims court is an option (the limit in New York City small claims court is $10,000).

Attorney’s Insight

In leak disputes, the outcome is often decided before closing. A few steps at contract signing are far more effective than a lawsuit afterward:

• Make key representations survive closing, for example that “the roof and basement have not leaked in the past several years,” with a stated survival period;
• Ask the seller in writing whether the home has leaked or had insurance claims, and ask for repair records. Written questions and answers are the strongest evidence if you later claim fraud;
• Take inspection notes about “elevated moisture” or “possible old water stains” seriously. Have a professional follow up with a moisture meter or thermal imaging, or negotiate an escrow holdback at closing.

If you do find a problem after closing, don’t give up too quickly. If there is evidence the seller deliberately hid it, bringing in an attorney early to preserve evidence is often the key to recovering your loss.
