Why a separate policy
Most homeowners insurance does not cover flood damage. Flood insurance is a separate policy that can cover buildings, the contents of a building, or both. The National Flood Insurance Program (NFIP) is managed by FEMA and sold through participating insurance companies; private flood insurance also exists.
Waiting period
There is typically a 30-day waiting period before an NFIP policy takes effect, so do not wait until a storm is forecast. Exceptions include no wait when you buy flood insurance while making, increasing, extending or renewing a mortgage, and a one-day wait when your property is in a newly designated high-risk flood zone and you buy within 12 months of the map update.
Who should consider it
Flooding can happen outside high-risk flood zones. If your mortgage lender requires flood insurance you must buy it; if not, it may still be worth considering. Renters can buy contents coverage.
What flood insurance can cover
Building coverage protects the structure and certain fixtures, and contents coverage protects belongings. Renters can buy contents coverage. Check what is and is not covered in the policy.
How to buy
- Check your flood risk on FEMA’s tools.
- Ask an insurance agent about NFIP and private options.
- Buy early because of the waiting period.
- Review your policy each year.
