Do I need flood insurance?
Your homeowners policy won't pay for flood damage — and a quarter of flood claims come from low-risk areas. Here's what to know.
Flooding is the most common and costly natural disaster in the U.S. — and standard homeowners insurance specifically excludes it. Flood insurance is a separate policy, and more people need it than realize it.
Who needs it
If you have a government-backed mortgage on a home in a high-risk flood zone, flood insurance is required. But risk isn't binary: about a quarter of flood claims come from low-to-moderate risk areas. Just one inch of water can cause around $25,000 in damage, so coverage is worth considering even outside mapped flood zones.
What it covers and costs
A standard federal (NFIP) policy provides up to $250,000 in building coverage and up to $100,000 for contents. The national average premium is roughly $1,000 a year, but it varies widely by flood zone and elevation — private flood insurers may offer higher limits or different pricing.
How to check your risk
- Look up your address on FEMA's flood map to see your zone.
- Ask whether your lender requires coverage.
- Remember there's typically a 30-day waiting period before a new flood policy takes effect — don't wait for a storm in the forecast.
