Most homeowners and renters insurance does not cover flood damage. Flood coverage is a separate policy. The federal National Flood Insurance Program (NFIP), managed by FEMA, sells it through insurance companies and agents. Here is what NFIP policies cover and exclude, the coverage limits, the waiting period, when a lender requires it, and how to buy, each fact copied from FEMA or federal law with its source. Checked 2026-10-13.
| Coverage | Maximum |
|---|---|
| Home (building) | $250,000 |
| Home or renter (contents / belongings) | $100,000 |
| Business (building) | $500,000 |
| Business (contents) | $500,000 |
Building and contents coverage are typically bought separately and have separate deductibles. Renters can buy contents coverage only. An NFIP policy lasts one year, with a 30-day grace period after it expires if you renew and pay in full by the end of that period.

It covers direct physical flood damage to your home and belongings.
FEMA's standard policy defines a flood as two or more acres of normally dry land, or two or more properties, partly or fully under water from overflowing inland or tidal waters, unusual and rapid surface-water runoff, mudflows, or collapse of land along a lake or other body of water caused by waves or currents. NFIP also pays up to $1,000 to protect insured property and up to $1,000 to move it away from an imminent flood (for example sandbags, pumps, plastic sheeting).

The cause matters: a sewer backup from a heavy rainstorm's flooding is covered, but a sewer backup from clogged pipes is not. No matter the cause, NFIP policies don't cover:

NFIP coverage generally starts 30 days after you buy, which is why FEMA says to plan ahead. FloodSmart lists four exceptions:

Congress must renew the NFIP's authority periodically. On Sept. 2, 2026, legislation extended it to Dec. 11, 2026. FEMA says that if authorization lapses it can still pay valid claims with available funds, but it would stop selling and renewing policies.

Private insurers also sell flood policies outside the NFIP. Federal law requires covered lenders to accept a private policy that meets the mandatory-purchase coverage requirements (42 U.S.C. § 4012a (flood insurance purchase requirement), via Cornell LII). Private policies' prices, limits and waiting periods are set by each insurer, so compare the policy wording with NFIP's limits and exclusions above. We don't have sourced data on private flood prices, so we don't show any.

Usually not. FEMA says most homeowners and renters insurance doesn't cover flood damage; flood coverage is a separate policy, often from the NFIP.
Up to $250,000 for a home's building and $100,000 for contents; businesses can get up to $500,000 each for building and contents (FloodSmart.gov).
Generally 30 days after purchase. Exceptions: no wait when buying with a new, increased, extended or renewed mortgage or when changing coverage at renewal; one day after a flood-map change (within 12 months) or post-wildfire flooding on federal land (within 60 days of containment).
Yes for properties in high-risk zones (A or V on FEMA maps) with a mortgage from a federally regulated, insured or agency lender, in NFIP communities. The lender must accept a qualifying private flood policy.
No. Every company and agent selling NFIP policies uses the same FEMA pricing.
