How to Get Flood Insurance
Flood insurance is a separate policy you buy from the National Flood Insurance Program or a private insurer, not an add-on to homeowners coverage
Standard homeowners insurance does not cover flood damage — water that rises from heavy rain, overflowing rivers, storm surge, or melting snow. If you live in or near a flood zone, you need a separate flood policy. The National Flood Insurance Program (NFIP), run by the Federal Emergency Management Agency (FEMA), is the largest source of flood coverage in the United States. Private insurers also write flood policies, and some offer lower rates or broader coverage than NFIP.
You can buy flood insurance whether or not your mortgage lender requires it. If your property is in a high-risk flood zone and you have a federally backed mortgage, your lender will require it. Even if you are not required to carry it, flood insurance protects your home and belongings from a real financial loss — a single flood can cost tens of thousands of dollars to repair.
Key Takeaways
- Flood insurance is sold separately from homeowners insurance and covers damage from rising water, heavy rain, and storm surge.
- The National Flood Insurance Program (NFIP) is available in most communities, but private flood insurers may offer lower rates or different coverage limits.
- There is typically a 30-day waiting period before NFIP coverage takes effect, so buying early matters if a storm is forecast.
- Your flood zone determines your premium — properties in high-risk zones pay significantly more than those in moderate or low-risk areas.
- You can find your flood zone and compare rates through FEMA's Flood Map Service Center, your insurance agent, or private insurers directly.
How to learn about you are in a flood zone
Your flood zone determines whether your lender requires coverage and what you will pay. FEMA divides land into zones based on flood risk. High-risk zones (labeled A or AE on flood maps) have a 1 percent or greater chance of flooding in any given year. Moderate-risk zones (B or X, shaded) have between a 0.2 and 1 percent annual risk. Low-risk or minimal-risk zones (C, D, or X, unshaded) have less than a 0.2 percent annual risk.
Check your flood zone using FEMA's Flood Map Service Center at msc.fema.gov. Enter your address and view the official flood map for your area. You can also call your local floodplain manager or ask your insurance agent to look it up for you. If you believe the map is wrong — for example, if your home sits on higher ground than the map shows — you can request a Letter of Map Amendment (LOMA) from FEMA, though this process takes time and requires surveying.
Buying flood insurance through the National Flood Insurance Program
NFIP policies are sold through private insurance agents and brokers, not directly from FEMA. To find an agent who sells NFIP coverage, visit floodsmart.gov or call 1-888-379-9531. You will need your property address, the date you want coverage to start, and information about your home — its age, construction type, and whether the first floor is at or below ground level.
NFIP premiums are based on your flood zone, the replacement cost of your home, and the elevation of your first floor relative to the base flood elevation. A home in a high-risk zone with a basement can cost $1,000 to $3,000 or more per year; a home in a low-risk zone might cost $300 to $600 annually. Rates vary widely, so get quotes from multiple agents.
NFIP policies have a 30-day waiting period before they take effect, except in cases where the policy is required by a mortgage lender (then it takes effect immediately). This means if you buy a policy today, it does not cover floods that occur for the next 30 days. If a hurricane or heavy rain is forecast, buying early matters.
Comparing private flood insurance options
Private insurers have entered the flood insurance market in recent years and may offer rates lower than NFIP, especially for homes in moderate-risk zones or homes that have been elevated or improved. Private policies may also offer higher coverage limits or cover items NFIP does not, such as detached garages or pool equipment.
The trade-off is that private insurers are not backed by the federal government. If a catastrophic flood affects many properties at once, a private insurer could become insolvent, though most states require insurers to maintain reserves. Ask your insurance agent which private flood insurers operate in your state and request quotes from at least two.
Some private insurers require that you carry NFIP coverage first, or they will only cover the amount above NFIP's limits. Understand the terms before you commit. If you switch from NFIP to private coverage, your new private policy will also have a waiting period unless it is required by your lender.
What flood insurance covers and what it does not
NFIP covers direct physical damage to your home's structure caused by flooding — foundation repair, wall and floor damage, electrical systems, and built-in appliances. It also covers personal property inside your home, though personal property coverage has a separate, lower limit (usually $100,000 compared to $250,000 for the structure).
NFIP does not cover damage from water that backs up through sewers or drains, damage from wind-driven rain that enters through broken windows or doors, or damage that occurs before the policy takes effect. It does not cover temporary housing, loss of use, or items stored in a basement or crawl space below the base flood elevation. Basements are particularly limited — NFIP covers the structure but not the contents.
Private policies vary. Some cover sump pump failure or water backup, which NFIP does not. Read the policy language carefully and ask your agent what is and is not covered before you buy.
Costs and how to lower your premium
NFIP premiums are set by FEMA and do not vary between agents, though agents may charge different service fees. Your premium depends on your flood zone, the replacement cost of your home, and your home's elevation. A home in an AE zone (high-risk) with a first floor at or below the base flood elevation pays the highest rates. A home in a low-risk zone pays substantially less.
You can lower your premium by elevating your home, installing flood vents in foundation walls, or moving utilities and mechanical systems above the base flood elevation. These improvements take time and money upfront but can reduce your annual premium by 30 percent or more. Ask your agent whether your specific improvements will lower your rate before you invest in them.
If you have not had a claim in five years, NFIP offers a 10 percent discount. Some states and communities also offer grants or low-interest loans to help homeowners make flood-resistant improvements. Contact your local floodplain manager or your state's emergency management office to learn what is available in your area.
Renewing and updating your flood insurance
Flood insurance policies renew annually. NFIP policies renew automatically unless you cancel, and your agent will send you a renewal notice 30 to 60 days before expiration. Review the renewal carefully — if you have made improvements to your home or if flood maps have changed, your premium or coverage may shift.
If you sell your home, your flood policy does not transfer to the new owner. The new owner will need to buy their own policy. If you are buying a home in a flood zone, you can buy a policy before closing, and it will take effect on the day you take ownership (no waiting period if the lender requires it).
If FEMA updates the flood map for your area and your home moves to a lower-risk zone, contact your agent — your premium may decrease. If your home moves to a higher-risk zone, your premium will increase, usually on your next renewal.
Frequently Asked Questions
Do I need flood insurance if I am not in a high-risk flood zone?
No, it is not required by your lender. However, about 20 percent of flood claims come from properties outside high-risk zones, often from localized flooding, poor drainage, or storm surge. Whether to buy coverage is a personal decision based on your risk tolerance and the cost of potential repairs.
Can I buy flood insurance after a flood watch or warning is issued?
Yes, but NFIP policies have a 30-day waiting period. If a flood watch is in effect, you can buy a policy, but it will not cover floods that occur in the next 30 days. Private insurers may also impose waiting periods or decline to write new policies during active weather events.
What happens if I do not have flood insurance and my home floods?
You will pay for repairs out of pocket. FEMA may offer disaster assistance grants if a federal disaster is declared, but these grants are limited and do not cover all losses. Homeowners insurance will not cover the damage. Without flood insurance, a single flood can result in tens of thousands of dollars in uninsured losses.
How do I file a flood insurance claim?
Contact your insurance agent or the insurer directly as soon as it is safe to do so. Document the damage with photos and video. Keep receipts for emergency repairs and temporary housing. NFIP claims are typically processed within 30 to 60 days, though complex claims may take longer.
Can I cancel my flood insurance if I pay off my mortgage?
Yes, once your mortgage is paid off, your lender cannot require you to carry flood insurance. However, if you live in a high-risk zone, canceling leaves you exposed to significant financial loss. Many homeowners choose to keep coverage even after the mortgage is gone.
