What Happens If Your Condo Floods? Who Pays: You, the Board or Insurance

Updated · 5 min read

Short answer: It depends on where the water came from. If a shared pipe, riser (the main vertical pipe) or the roof failed, the condo usually repairs the building and its insurance responds. If the water came from a unit, through an overflowing tub, a burst dishwasher hose or a renovation gone wrong, that owner is usually responsible. 83% of the 2,319 NYC condo offering plans we read say that repairs made necessary by an owner's negligence, misuse or neglect are charged to that owner. What's inside your own walls, from your floors to your appliances, is mostly yours to insure.

First: What to Do When the Water Starts

  1. Stop the water if you can: the fixture's shutoff valve, or your unit's main valve.
  2. Call the super or managing agent right away. They can shut off a riser, get into the unit above, and start finding the source.
  3. Document everything: photos and video of the damage and the source, before cleanup.
  4. Call your own insurer and tell the managing agent in writing. Many policies require prompt notice.
  5. Dry out quickly to limit mold, and keep receipts.

Who Pays Depends on the Source

Water from a common element: usually the condo

The board maintains and repairs the common elements: the structure, the roof, and the pipes and risers that serve more than one unit. When one of them fails, the repair is a common expense. The plan for 582 Park Place puts it plainly: repair of the roof "and resultant water damage" is the board's responsibility for common element areas, and the unit owner's for limited common elements, like a private roof terrace.

Water from a unit: usually that owner

Pipes and fixtures that serve only one unit are that owner's to maintain. At 103 Joralemon Street, the by-laws make owners responsible for repairs in their units, including "plumbing stoppages" and pipes "located in and exclusively servicing the Unit." And when an owner's negligence, misuse or neglect makes a building repair necessary, the cost is "assessed to and paid for by such Unit Owner," plus an administrative charge of 20% of the cost. That kind of clause is standard: we found it in 1,935 plans.

Gray areas

The hardest cases are a slow leak nobody noticed, a pipe that failed inside a wall at the joint between a riser and a unit's branch line, and terraces over someone else's ceiling. The answer turns on the exact wording of the declaration and by-laws, and often on what the plumber finds. See who fixes what in a NYC condo and terrace repairs.

How the Insurance Splits

A condo has two layers of insurance, and in a flood both may be involved.

The building's policy

The board insures the building. How far that coverage reaches into your unit varies by plan:

Your policy (HO-6)

Many by-laws require owners to carry their own insurance and name water damage specifically. The Morgan requires each owner to carry liability insurance covering claims "including, but not limited to, loss due to water damage" from the unit, and property insurance for the unit's improvements and betterments and "loss due to water damage." We found that requirement in 465 plans. Other plans recommend it instead: Bellrose suggests owners consider "water damage legal liability to cover damage arising from leaks or other conditions within the unit," and 82 Sterling Place instructs owners to carry coverage for water damage and "sewer and drain back up."

The liability part matters most. If water from your unit damages the apartments below, your policy is what pays your neighbors. See condo insurance vs. homeowners insurance.

The deductible

Even when the building's policy pays, someone covers the deductible. At 45 West 81st Street, owners share any deductible on the common elements by percentage, but each owner "shall be fully responsible for any deductible with respect to insurance covering damage to the Unit itself." We found clauses putting a deductible on the owner in 128 plans. Building deductibles can run into the thousands, so it's worth having loss assessment coverage on your own policy.

FAQ

Is the condo association responsible for water damage to my unit?

If the water came from a common element like a riser or the roof, the condo is usually responsible for the building repair, and its policy may cover your unit's original finishes. Your improvements, belongings and any deductible are usually on you and your own insurance.

My upstairs neighbor's unit leaked into mine. Who pays?

Usually the neighbor, if the leak came from their fixtures, appliances or carelessness, often through their liability insurance. In practice, your own insurer may pay you first and then go after the neighbor's insurer.

Can the board charge me for a leak that started in my unit?

Yes, under most by-laws. 83% of the NYC condo plans we read let the board charge an owner for repairs caused by their negligence, misuse or neglect, sometimes with an administrative fee on top.

Do I need HO-6 insurance in a NYC condo?

Usually yes, and many by-laws require it, with water damage named specifically. Your lender will likely require it too.

Does condo insurance cover flooding from a storm?

Water from a burst pipe and water from outside are treated differently. Standard policies generally exclude flooding from storms or rising water, which needs separate flood insurance. Ask the board whether the building carries it.

Where this comes from: the declarations, by-laws and insurance notes in 2,319 NYC condo offering plans, searched for owner-negligence repair clauses, owner insurance requirements that name water damage, board policies covering original kitchen and bath equipment, and deductible clauses; and the plans for 582 Park Place, 103 Joralemon Street, 842 Sixth Avenue, The Morgan, Bellrose, 82 Sterling Place and 45 West 81st Street. Every building is different, and its own documents and policies control. This is general information, not legal or insurance advice. Updated November 2026.
