Co-op vs. condo repairs: who handles what in NYC buildings
A Brick Underground guide explains who handles common repairs in NYC co-ops and condos. In co-ops, the proprietary lease controls. A rule of thumb puts anything you can touch on the shareholder, with exceptions like in-wall wiring, steam risers and the front door. Condo owners may have to fix damage themselves and sue a negligent neighbor later.

What happened
Brick Underground published a guide on October 16, 2026 explaining who usually pays for common repairs in New York City co-ops and condos. An editor's note says the piece first ran in September 2021 and was updated with information for August 2025. The main point is that the answer depends on the type of building. Condo buyers get a deed and own their unit. Co-op buyers are shareholders in a corporation and sign a proprietary lease, which works much like a rental lease.
For co-ops, attorney Marc J. Luxemburg of Gallet Dreyer & Berkey describes a "rule of thumb nail." Anything you can touch with a finger or fingernail is usually the shareholder's job. Deeper parts of the building are usually the board's. Attorney Andrew Freedland of Herrick, Feinstein said that "nine times out of 10" windows are the co-op's responsibility. He added that many co-ops converted in the 1970s and 1980s, and some have amended their leases to shift that duty to shareholders. Plumbing inside the walls usually falls to the board. Faucets, toilets and sinks usually fall to the shareholder.
There are exceptions. Electrical wiring inside the walls is typically the shareholder's responsibility. In prewar co-ops, exposed steam risers belong to the board. The unit's front door belongs to the board, but the shareholder handles painting and any extra lock beyond the standard one.
The warranty of habitability protects NYC renters and also co-op shareholders, but it does not apply between a condo board and its unit owners. Condo owners with water damage from a neighbor generally must fix it themselves and sue later, and they would need to prove negligence. A co-op shareholder can call 311 about bad paint or wall coverings, but Luxemburg warned the board may then charge the shareholder for the work and possibly legal costs, since "the legal codes don't supersede the proprietary lease."

What it means
Buyers and owners
Before you pay for a repair, read your proprietary lease or condo documents, because amendments can shift duties like windows or insurance. Condo owners have no habitability claim against the board and may have to fix damage first and sue later.
Landlords
If you rent out a condo or co-op unit, you take on warranty of habitability duties to your tenant, even though a condo board owes you no such duty. Plan for repair costs you may not be able to pass to the building.
Tenants and voucher holders
Renters, including those subletting in a co-op or condo, are protected by the warranty of habitability through their landlord. Your landlord may be the unit owner, not the building board, so report problems to the person you rent from.
The highlights
- Co-op boards cover windows nine times out of 10, per attorney Andrew Freedland.
- Pipes inside walls usually fall to the co-op; faucets, toilets and sinks to the owner.
- Condo owners get no warranty of habitability from their board.
Why it matters Landlords
Owners who rent out a condo take on warranty of habitability duties to their tenants, even though the board owes them none.
What to do: Check your proprietary lease before paying for a repair.

Background
In New York City, housing code complaints made through 311 are generally routed to the Department of Housing Preservation and Development (HPD), which can inspect and issue violations to building owners. Co-ops and condos are run by boards under their own governing documents, so private agreements like a proprietary lease or condo bylaws often decide who pays for a repair, even when a city code sets the minimum condition that must be met.
