Do You Need Flood Insurance in Ohio?

Updated November 1, 2026 · General information, not insurance advice

Standard homeowners policies in Ohio don't cover flood damage. If water rises from a river, Lake Erie, a creek or heavy rain and enters your home, you need a separate flood policy to be covered. Many Ohio flood claims come from homes outside high-risk flood zones.

Who in Ohio should think about flood insurance?

Homes near the Ohio River, Lake Erie, the Maumee, Great Miami, Scioto or Muskingum rivers, or any creek or low-lying area
Homes with basements in areas where streets or yards flood during heavy rain
Anyone whose lender requires it because the home is in a mapped high-risk flood zone

Two ways to buy flood insurance

National Flood Insurance Program (NFIP)

The federal program, run by FEMA, sells policies through regular insurance agents. For a home, NFIP coverage tops out at $250,000 for the building and $100,000 for belongings. You can check your flood risk and find an agent at FloodSmart.gov.

Private flood insurance

Some private companies sell flood policies with higher limits or extras such as temporary living costs. Prices and availability vary by address.

Don't wait for the forecast: the 30-day waiting period

NFIP policies normally don't start until 30 days after you buy. A storm in the forecast is too late. There are exceptions, for example when you buy coverage as part of getting a mortgage, or within 13 months after your area's flood map changes. Private flood policies often have shorter waits, commonly 10 to 14 days.

What flood insurance typically covers

The structure: foundation, walls, electrical and plumbing, furnace and water heater
Built-in appliances, flooring and cabinets
Belongings, if you buy contents coverage

Basement coverage under the NFIP is limited, so finished basements and items stored there may not be fully covered. Ask your agent what applies to your home.

Sewer backup is different

Water that backs up through drains or a failed sump pump is usually not flood. It is covered by an optional water backup endorsement on your homeowners policy. It's inexpensive and worth asking about if you have a finished basement.
