THE DOCKET / TOO LATE BEFORE YOU KNEW — THE FOUR-MONTH WINDOW
What the board is said to have done
Adopted house rules five months after a penthouse sale making that owner responsible for protecting the roof membrane beneath his terrace and indemnifying the cooperative for any damage to it.
No tribunal ever decided this.

What the court held
A cooperative shareholder challenging a board's action must proceed under CPLR article 78, which carries a four-month statute of limitations running from the date the determination becomes final and binding -- that is, from notification. A plenary action brought eleven months after the house rules issued was time-barred, and the claim could not be salvaged by recasting it as a breach of the proprietary lease. Separately: a terrace for the shareholder's own exclusive outdoor use is an amenity, not an essential function, so the implied warranty of habitability does not reach it.
“Where, as here, a cooperative shareholder seeks to challenge a co-op board's action, such challenge is to be made in the form of an article 78 proceeding”
154 AD3d at 403
Outcome in full
The board prevailed on the appeal. Dismissal of the house-rules challenge as time-barred affirmed, with costs; denial of leave to amend affirmed; the co-op's motion to quash the shareholder's nonparty subpoenas to its accountant and its roofer affirmed. Some claims survived below (a declaration as to three doors, and a breach-of-contract claim against the co-op), which is why the docket is still open.
The harm continued while the case ran
The shareholder bought a penthouse in February 2013 without ever inspecting its terrace, because the roof was under renovation. The house rules adopted five months later made him responsible for protecting the roof membrane and indemnifying the co-op for any damage. The terrace condition was never adjudicated: the claim died on the limitations period, not on the facts. The docket remains ACTIVE as of 2026-08-04 -- twelve years after filing.
What it cost
Not disclosed. No decision in this case states a figure, and we publish no estimate. Why costs are mostly blank.
What would have prevented this
A statutory challenge window measured from DISCOVERY rather than notification -- or an administrative complaint channel with no four-month bar -- would have let this dispute be decided on whether the terrace was usable. Instead it was decided on a calendar. Note the compounding effect: RPL 339-w would not have entitled this owner to the board's minutes or engineering reports in the first place, so the information needed to evaluate the decision was not obtainable inside the period allowed to challenge it.
