Standard homeowners policies do not cover flood. The National Flood Insurance Program caps a home at $250,000 for the structure and $100,000 for belongings, pays contents at actual cash value, and pays the building at replacement cost only for a principal residence insured to at least 80% of replacement cost or the program maximum. Excess flood sits on top of an NFIP or private primary policy, and private primary flood can offer higher limits from the first dollar. Lenders require only the lesser of the loan balance or the program maximum, which is rarely the cost of rebuilding an expensive home.
What the NFIP covers, and where it stops
FEMA’s FloodSmart site sets the ceiling: up to $250,000 for a home’s structure and up to $100,000 for belongings inside. For valuable items such as original artwork and furs, contents coverage is limited to $2,500.
How a claim is valued matters as much as the limit. Under the NFIP dwelling form, replacement cost settlement applies to a single-family dwelling only if it is your principal residence, meaning you or your spouse lived there at least 80% of the prior 365 days, and it is insured to at least 80% of full replacement cost or the program maximum. Otherwise the building is paid at actual cash value. The Insurance Information Institute notes contents are paid at actual cash value.
That is why a second home on the water can face a depreciated payout on top of the dollar cap.
What an NFIP policy leaves out
- Temporary housing and additional living expenses while the home is repaired.
- Personal property kept in basements.
- Property outside the building, such as landscaping, septic systems, decks, patios, fences and swimming pools.
- Currency, precious metals, stock certificates and other valuable papers.
- Cars and most self-propelled vehicles.
On an expensive home, the outdoor improvements and the cost of living elsewhere during a long rebuild can be large numbers. Ask whether a private policy treats any of them differently.
How excess and private flood fill the gap
The Insurance Information Institute describes two private options. Private primary, or first-dollar, flood policies work like an NFIP policy but generally offer higher coverage. Excess flood sits over and above a primary policy, and it can be bought whether the primary policy is from the NFIP or a private insurer.
Excess flood is also an option for homeowners in communities that do not participate in the NFIP, and the Insurance Information Institute says it is available in all parts of the country, in high-risk zones and in lower-risk areas alike.
The cleanest setup on a high-value home is the one where the primary and excess limits, deductibles and waiting periods are designed together. More on the flood insurance page.
What your lender requires, and what it accepts
Federal flood rules set a floor, not a target. For an FDIC-supervised lender, the flood insurance on a designated loan must be at least the lesser of the outstanding principal balance or the maximum coverage available under the program, and it covers the building and personal property securing the loan, not the land.
Since July 1, 2019, federally regulated lenders must accept private flood insurance that meets the statutory definition, and lenders may rely on a statement in the policy saying it meets that definition. They may also accept some private policies that do not meet the definition, under conditions.
A policy that satisfies the lender may still leave most of an expensive home uninsured for flood.
Timing and who should look at excess flood
NFIP coverage generally starts 30 days after purchase. FloodSmart lists exceptions, including no wait when the policy is bought in connection with making, increasing, extending or renewing a mortgage. Private policies set their own terms, so ask.
- Homes in or near a mapped flood zone, on the coast, or near rivers and lakes.
- Homes where rebuild cost is well above $250,000, which describes nearly every home in this price range.
- Homes with finished lower levels, valuable contents or extensive outdoor improvements.
- Second homes, where NFIP building claims are paid at actual cash value.
Common questions
What are the NFIP limits for a home?
Up to $250,000 for the building and up to $100,000 for contents, according to FEMA’s FloodSmart site.
What is excess flood insurance?
A policy that pays above a primary flood policy’s limits. The Insurance Information Institute notes it can sit over an NFIP or a private primary policy.
Will my mortgage lender accept private flood insurance?
Federally regulated lenders must accept private flood policies that meet the federal definition of private flood insurance, and may accept some others under conditions.
Does NFIP pay replacement cost on my vacation home?
Not for the building. Under the NFIP dwelling form, replacement cost applies only to a principal residence that meets the insurance-to-value test; otherwise the building is paid at actual cash value.
Is there a waiting period for flood insurance?
NFIP policies generally take effect 30 days after purchase, with exceptions such as a purchase tied to a mortgage closing. Private policies set their own waiting periods.
