Flood Insurance in Brooklyn, NY: Storm Surge, Basement Flooding, and Quotes
Flood insurance in Brooklyn covers two very different risks. Superstorm Sandy pushed the ocean into Red Hook, Coney Island, Sheepshead Bay, and Gerritsen Beach in 2012, and on September 29, 2023, 7.32 inches of rain fell on the borough and flooded streets and basements far from the water.
Standard homeowners, condo, and renters policies exclude flood, yet a 2019 investigation by THE CITY found only 14% of Canarsie homeowners had flood insurance.
Blake Insurance Group is an independent agency based in Tucson that serves Brooklyn homeowners and renters by phone and online.

Flood risk in Brooklyn: what drives it
Brooklyn has miles of waterfront, canals, and low-lying neighborhoods built on former marsh. Three things drive most flood claims.
Storm surge on the waterfront and canals
During Sandy, Red Hook flooded on all sides, Coney Island’s streets filled with water and sand, and water spread from the Gowanus Canal and Newtown Creek.
Cloudburst rainfall
Intense storms in 2021 and 2023 overwhelmed sewers, flooding streets in neighborhoods such as Williamsburg and basements across the borough.
Low insurance take-up
Most properties in flood-prone areas are uninsured, so a single storm can cause large uninsured losses.
Brooklyn flood zones and maps
Higher-risk flood zones cover much of Red Hook, Coney Island, Sea Gate, Brighton Beach, Manhattan Beach, Sheepshead Bay, Gerritsen Beach, Canarsie, and the Gowanus and Newtown Creek waterfronts. Many inland blocks are outside those zones but still flood in cloudbursts.
FEMA flood maps label higher-risk areas as Special Flood Hazard Areas, such as Zones A and AE, and lower-risk areas as Zones X, B, or C. If your building is in a high-risk zone and you have a federally backed mortgage, your lender will require flood insurance. Outside those zones, coverage is optional, but flood damage is still excluded from standard homeowners and renters policies.
You can look up an address on the FEMA Flood Map Service Center. Maps show estimated risk, not a guarantee, and do not capture every street or wash that floods during a heavy storm.
Coverage priorities for Brooklyn homeowners and renters
| Your situation | Coverage to review | Why it matters |
|---|---|---|
| Homeowner in Gerritsen Beach, Sheepshead Bay, or Canarsie | Building and contents flood | These areas flooded in Sandy and many homes are uninsured |
| Renter in a basement or ground-floor apartment | Contents-only flood and renters water backup | Your landlord’s policy does not cover your belongings |
| Condo or co-op owner | Unit flood coverage alongside the building’s master policy | The building policy may not cover your improvements or belongings |
| Buying a home with a mortgage | Flood zone and flood history check | New York sellers must now disclose flood zone and claim history |
Examples only, not recommendations. Coverage availability and terms vary by insurer.
New York flood facts every Brooklyn property owner should know
- Flood is excluded from homeowners and renters policies. Rising water from the ocean, a bay, a canal, or an overloaded sewer, or heavy rain that pools around a building, is flood damage. It needs a separate flood policy.
- Sewer backup is a separate gap. Water backing up through floor drains or toilets is usually covered only by a water backup endorsement on your homeowners policy. A flood policy covers backup only when it is caused directly by a flood.
- Basements have limited flood coverage. NFIP policies cover only certain items below ground level, such as furnaces, water heaters, and washers and dryers, not finished walls, flooring, or most belongings. Some private policies offer more.
- New York sellers must answer flood questions. Since March 20, 2024, the Property Condition Disclosure Statement asks whether a home is in a FEMA floodplain or flood hazard area, whether it has flood insurance or an elevation certificate, and whether the seller received federal flood aid or filed a flood claim. Sellers can no longer give a $500 credit instead of the form.
- Leases must disclose flood risk. Since June 21, 2023, New York residential leases must say whether the property is in a FEMA floodplain or flood hazard area and whether it has had flood damage, and remind renters that renters insurance usually excludes flood.
- Lenders require flood insurance in high-risk zones. If your building is in a Special Flood Hazard Area and your mortgage is federally backed, flood insurance is required. Elsewhere it is optional.
- State floodplain help. The New York State Department of Environmental Conservation is the state’s NFIP coordinating agency, and 1,466 New York communities take part in the NFIP.
NFIP vs. private flood insurance: what to compare
Most flood policies come from the National Flood Insurance Program, run by FEMA, or from a private flood insurer. Line up each quote on the same terms before comparing price.
| Coverage | What to compare |
|---|---|
| Building coverage | Same limit. The NFIP pays up to $250,000 for a home's structure. Private flood insurers may offer higher limits. |
| Contents coverage | Same limit. The NFIP pays up to $100,000 for belongings, and renters can buy contents-only coverage. |
| Deductibles | Same deductibles. Building and contents deductibles are often separate. |
| Loss settlement | Whether the building is paid at replacement cost or actual cash value, and how contents are paid |
| Living expenses | The NFIP does not pay for a hotel or other extra living costs. Some private policies do. |
| Basements | The NFIP limits what it covers below ground level. Check what each policy pays for in a basement. |
| Waiting period | NFIP policies usually take effect after 30 days, with some exceptions, such as a loan closing. Private waiting periods vary. |

Flood insurance is priced by the exact address, including its flood risk, the building's elevation and foundation, its replacement cost, and the coverage and deductibles you choose. Have your address and, if you have one, your elevation certificate ready.
Ways to lower your Brooklyn flood premium
- Compare NFIP and private quotes. Since FEMA's Risk Rating 2.0, NFIP prices reflect each property's own risk, and a private quote can come in higher or lower for the same home.
- Choose a higher deductible if you can afford it after a loss.
- Get an elevation certificate. It can help, especially for buildings in high-risk zones.
- Reduce the damage a flood can do. Raising utilities, adding flood openings, or elevating the building can lower the price over time.
- Ask about community discounts. Communities in FEMA's Community Rating System can earn NFIP discounts for their residents.
Discounts and pricing factors vary by insurer and program.
Closing on a home? If your lender requires flood insurance, tell us your closing date. NFIP policies tied to a loan closing can start without the usual 30-day wait. Call 888-387-3687.
