New York · Construction-defect rights
Here is what you have, and here is how to keep it.
New York gives every new-home buyer a warranty that the builder cannot make you sign away: one year on workmanship, two on plumbing, electrical and heating, six on material defects. It stays with the home when it is sold. The trap is the notice - the builder must receive your written notice before you file any lawsuit and no later than 30 DAYS after the relevant warranty period ends, and owners have lost otherwise good claims on that alone. In one condominium case the six-year period did not apply because the defects were not "major structure", leaving the one- and two-year periods, and the notice had been missed on both. Write down what you find, the day you find it.
What you have
YOUR WARRANTY CANNOT BE SIGNED AWAY. GBL s.777-a(5) makes any contract term excluding or modifying the housing merchant implied warranty VOID AS CONTRARY TO PUBLIC POLICY. Every new home carries it automatically - 1 year skillful construction, 2 years plumbing/electrical/heating/cooling/ventilation, 6 years material defects - and it SURVIVES THE PASSING OF TITLE, so it is still there if you bought from the first owner. New York has no general statute of repose for buildings, but that does not mean there is no deadline: claims must be brought within 3 years for injury to property (CPLR 214(4)) or 6 years on a written contract (CPLR 213(2)), and courts often start that clock at completion, not discovery.
The deadline
New York has no general statute of repose for construction
None — New York has no statute of repose for improvements to real property
New York has NO general statute of repose for construction or improvements to real property. Claims run under the CPLR from ACCRUAL, not a fixed outer deadline: 3 years for injury to property (CPLR 214(4)) and 6 years for breach of a written construction contract (CPLR 213(2)). CPLR 214-d adds a notice-of-claim requirement for actions against licensed design professionals (architects/engineers/surveyors) but is NOT a general construction repose. Accrual for latent defects is contested in NY case law and often runs from completion — dating accrual for a specific claim needs counsel.
“CPLR 214: "The following actions must be commenced within three years: ... 4. an action to recover damages for an injury to property except as provided in section 214-c". CPLR 213: "The following actions must be commenced within six years: ... 2. an action upon a contractual obligation or liability, express or implied".”
Before you sue: THE 30-DAY TRAP, verbatim from s.777-a(4)(a): written notice of a warranty claim "must be received by the builder prior to the commencement of any action... and no later than thirty days after the expiration of the applicable warranty period." The owner must afford the builder reasonable opportunity to inspect, test and repair. Courts have barred claims solely for missing this - in one condominium case the six-year material-defect period did not apply because the defects were not "major structure", leaving only the 1- and 2-year periods, and the owners had missed the 30-day notice on those. FILING WINDOW s.777-a(4)(b): an action may be commenced up to one year after the applicable warranty period expires, OR within four years after the warranty date, WHICHEVER IS LATER. If the builder makes repairs in response to a claim, a further period applies. (N.Y. Gen. Bus. Law s.777-a(4))
What to do now
Write it down the day you notice it. Photograph it with something for scale. Note the date, the room, and what you saw. If it gets worse, photograph it again - a sequence is far stronger than one picture. Keep every message with the builder. You are not starting a fight; you are keeping the option open. New York requires written notice to the builder before you sue: see "Before you sue" on this page for the exact rule. Describe each defect in reasonable detail; a record made at the time is what most people are missing later.
The same defect, a different answer next door
The construction-defect deadline is a state-by-state accident of geography. The identical crack in the identical house can be dead in one state and live in another.
