Does homeowners insurance cover flooding?

No. Standard homeowners, condo and renters policies exclude flooding. But some water damage is covered, and the difference matters when you file a claim.

The short answer

Homeowners insurance usually does pay for sudden water damage that starts inside your home, such as a pipe that bursts. It usually doesn't pay for water that comes in from outside and rises from the ground: an overflowing river, storm surge, heavy rain pooling around the house, or mudflow. That's a flood, and it needs a separate flood insurance policy.

What happened Homeowners policy Flood policy
A frozen pipe bursts and soaks the kitchen Usually covered Not a flood
Heavy rain floods the street and water comes in the front door Not covered Covered
A river overflows into the basement Not covered Covered, with basement limits
Storm surge from a hurricane Not covered Covered
Wind tears off the roof and rain pours in Usually covered (wind damage) Not a flood
Sewer or drain backs up into the house Only with a sewer backup add-on Only if the backup was caused by a flood
A slow leak under the sink rots the floor Usually not covered (wear and maintenance) Not a flood

Every policy is different. Read your own, or ask your agent, before you need it.

What counts as a flood

The National Flood Insurance Program defines a flood as water covering normally dry land, affecting at least 2 acres or two or more properties, for example from overflowing rivers or lakes, unusual and rapid buildup of rainwater, or mudflow. If only your house is wet and your neighbors are dry, it may not count as a flood, and the source of the water decides which policy, if any, pays.

Why it matters even outside a flood zone

A large share of NFIP flood claims come from outside FEMA's high-risk flood zones. Lenders only require flood insurance in high-risk zones, so many homes elsewhere have none. Policies in low- and moderate-risk zones often cost much less. See how much flood insurance costs.

Add-ons worth asking about

  • Sewer and drain backup coverage, added to a homeowners policy for a small extra cost. Floods aren't the only way water comes up through a basement drain.
  • Sump pump failure is usually part of the same add-on. A battery-backup sump pump helps too.
  • Flood insurance from the NFIP or a private insurer. A new NFIP policy usually takes 30 days to start, so buy it before storms are in the forecast. See flood insurance basics.

Renters

Your landlord's insurance covers the building, not your belongings. Renters insurance doesn't cover flooding either, but you can buy contents-only flood insurance from the NFIP, up to $100,000.
