Flood or water damage: which policy usually pays in New York

The basic split

Insurers draw the line by where the water came from. Water that rises from outside, from heavy rain across the ground, a river or a storm surge, is flood. Water that escapes from something inside the building, a pipe, a fixture, an appliance, is water damage. The two are usually covered by different policies.

This is general information, not advice about your policy. Wording varies, and your insurer or agent is the one who decides.

What homeowners, condo and renters policies usually cover

Standard policies usually cover sudden and accidental water from inside: a burst supply line, a washer hose that splits, a toilet overflow, a leak from the unit above. They usually don't cover slow leaks that went on for weeks, wear and tear, or water that came in from outside at ground level.

Rain that gets in because a storm damaged the roof or a window is often treated differently from flood, because the opening came first. Our storm damage page covers that kind of job.

What flood insurance usually covers

Flood policies cover damage from surface water that enters the home from outside, typically when it affects more than one property or a wide area. They usually treat basements differently from living space, with limits on what's covered below grade, so it's worth reading that section before a storm.

In low-lying parts of the city and along the Long Island shore, flood coverage matters. Our flood damage work is documented with the water line and removal lists flood adjusters ask for.

Where sewer backups fit

Sewer backups sit awkwardly between the two. Water coming up through a floor drain or toilet during a cloudburst isn't a burst pipe and isn't surface flooding, so many homeowners policies need a sewer backup endorsement to cover it. The city logged an average of 12,569 backup complaints a year between 2019 and 2023 (source), so it's worth checking whether yours has it.

Our guide on sewer backups covers the causes and prevention.

What to document for any claim

Photos and video of the source, the water, the damage in each room and the height of the water line. A timeline: when you noticed it, what you did and who you called. Damaged items kept until the adjuster says otherwise, and samples of flooring or materials that were removed.

From the restoration side, a daily drying log with moisture readings, a list of what was removed and why, and photos before and after each stage. That paperwork is what lets an adjuster approve the work quickly.

Renters, condo owners and co-op owners

Renters are usually responsible for insuring their own belongings, and flood coverage for contents can be bought separately from a building policy. In condos and co-ops, the association or corporation usually insures the building, and each owner looks after their own contents and, depending on the documents, some interior finishes.

After a flood, each of those parties may file separately. Records kept by unit, with each space's photos and removal lists, keep the claims from tangling.

After a regional storm

When a storm floods whole neighborhoods, adjusters are stretched and claims take longer. Start mitigation right away, keep every receipt and photo, and write down the date and time the water came in. Insurers generally expect you to limit the damage while you wait, and a complete record keeps your claim moving when everyone is filing at once.

Timing and deadlines

Report the loss as soon as you can; policies expect prompt notice. You're also expected to prevent further damage, which is why extraction and drying can start before the adjuster arrives. Keep receipts for emergency work, hotel stays and anything you buy to protect the property.

Flood policies can have their own timelines for filing proof of loss, so ask about them early.
