Do I need flood insurance?
Checked against FEMA and other official sources · Last reviewed October 8, 2026
You're required to carry flood insurance if your building is in a high-risk flood area (a Special Flood Hazard Area) and your mortgage comes from a federally regulated or federally backed lender. If your property has received federal disaster assistance before, you must have flood insurance to qualify for future disaster aid. Otherwise federal law generally leaves it to you, though your lender may still require it. But most homeowners and renters policies don't cover flood damage, and nearly a third of NFIP claims over the past 10 years came from outside high-risk zones. [1][2][3]

When flood insurance is required
Federal law sets the mandatory purchase rule. Lenders regulated by federal agencies may not make, increase, extend, or renew a loan secured by a building in an area FEMA has identified as having special flood hazards, in a community where NFIP insurance is available, unless the building is insured against flood "for the term of the loan." The same rule applies to federal agency lenders and to loans bought by Fannie Mae and Freddie Mac.
The required amount is the lesser of the loan's outstanding principal balance or the maximum coverage available for that type of property. For a single-family home, the NFIP maximum is $250,000 for the building.
FloodSmart puts it simply: "You're required to have flood insurance if you own a home or business in a Special Flood Hazard Area (SFHA) and have a government-backed mortgage." High-risk areas appear on flood maps as zones starting with A or V, such as zone AE, zone A, and zone VE. To check yours, see what flood zone am I in. [1][2][4][5]
Required after federal disaster aid
The flood insurance requirement can come from past aid as well as a mortgage. FloodSmart says: "If your property has received federal disaster assistance before, you must have flood insurance to qualify for future disaster assistance. This includes disaster grants from FEMA and U.S. Small Business Administration disaster loans."
FloodSmart says this requirement "is tied to a property, not an individual homeowner." So if you bought a home from someone who once got disaster aid for it, you need flood insurance to qualify for future aid. [2]
When it isn't required (and why you might buy it anyway)
If your home is outside a high-risk area, or you own it without a mortgage, federal law generally doesn't require flood insurance. Your lender may still require it. FloodSmart notes that "some banks require flood insurance even if you don't live in a high-risk area," so check your mortgage agreement.
Low or moderate risk isn't no risk. FloodSmart says "nearly one-third of NFIP claims are from outside the high-risk zones" over the past 10 years. It also says "99% of counties in the U.S. experienced a flood in the past 20 years." FloodSmart reports that NFIP policyholders "saw average claim payments of $68,000 from 2016–2021." Flood zone X explains what moderate- and low-risk zones mean. Flood insurance cost explains how prices differ by risk. [1][2][3][6]
Your homeowners or renters policy won't cover a flood
FloodSmart says "most homeowners insurance does not cover flood damage," and the NAIC, the association of state insurance regulators, says "the damage from a flood is not covered under a standard homeowner's policy." A homeowners policy also won't satisfy a mortgage or disaster-aid flood insurance requirement. FloodSmart says "only flood insurance meets those rules." For water damage that isn't a flood, see homeowners insurance and water damage. [2][6][7]
FEMA disaster assistance is not a substitute
Federal disaster assistance is only available after a presidential disaster declaration, and FloodSmart says "most flood events do not get a presidential disaster declaration."
When aid is available, it's limited. For disasters declared on or after October 1, 2025, FEMA's maximum Individuals and Households Program award per household is $44,800 for housing assistance and $44,800 for other needs. An NFIP policy can pay up to $250,000 for a home's structure and $100,000 for contents.
FloodSmart also says disaster aid "typically comes in the form of loans that must be repaid with interest," while flood insurance claim payments do not have to be paid back. More on aid programs is in FEMA assistance. [2][3][4][8]
Renters: contents-only coverage
If you rent, you can buy an NFIP contents-only policy for the things you own inside your home. FloodSmart says it covers "things like your furniture, clothes, television, computers, rugs and some artwork," up to $100,000. Under the policy form, a tenant's contents coverage also includes your stove and refrigerator. It can also cover improvements you paid for in your unit, up to 10% of your contents limit. Basement contents are limited; see what flood insurance covers. [5][9]
If you decide to buy
You can get NFIP coverage if your community participates in the NFIP, and FloodSmart says most U.S. communities do. FEMA keeps a list of participating communities. New policies usually take effect 30 days after purchase, unless you buy in connection with a mortgage closing, which has no wait. Rates are the same from every NFIP insurer, so you can use any participating agent or company. [2][9]
Questions people ask
Is flood insurance required in flood zone X?
Not by federal law, because zone X is outside the Special Flood Hazard Area. Your lender can still require it. FloodSmart says some banks require flood insurance even if you don't live in a high-risk area. [1][2][5]
Do I need flood insurance if my house is paid off?
The federal mortgage requirement applies for the term of a loan, so it generally doesn't apply once there's no loan. It's different if your property has received federal disaster assistance before. Then you must keep flood insurance to qualify for future aid, and that rule stays with the property. [1][2]
Can renters get flood insurance?
Yes. The NFIP sells contents-only policies to renters, covering belongings up to $100,000. [9]
Will FEMA pay to rebuild my house after a flood?
Not fully. Aid requires a presidential disaster declaration, which most floods don't get. For disasters declared on or after October 1, 2025, FEMA's housing assistance is capped at $44,800 per household. FloodSmart says much disaster aid comes as loans that must be repaid. [2][8]
Can I buy an NFIP policy right now?
Congress has to keep extending the NFIP's authority to sell new policies. Public Law 119-103 extended it to December 11, 2026. After that date, check FloodSmart or an agent for the current status. [10]
