Severe weather has also become increasingly costly. According to Climate Central, the U.S. experienced 23 weather and climate disasters that each caused at least $1 billion in damage in 2025, totaling approximately $115 billion. This was the third-highest annual number of billion-dollar disasters since 1980.
Unfortunately, standard homeowners insurance usually doesn't cover damage caused by flooding. That's where flood insurance comes in.
Flood insurance is a separate policy that helps cover types of flood-related damage. Depending on the property's location and mortgage, you may be required to carry coverage. But even if it's optional, understanding your flood risk and potential insurance costs can help you make a more informed homebuying decision.
What Does Flood Insurance Cover?
Flood insurance helps pay for covered damage caused by flooding, but the protection you receive depends on your policy. Generally, coverage falls into two categories: building coverage for the home's structure and contents coverage for personal belongings.
The National Flood Insurance Program (NFIP), managed by the Federal Emergency Management Agency (FEMA), offers these two types of coverage separately. Each has its own limits, and policies may exclude certain property or types of damage.
Building Coverage
Building coverage helps repair or rebuild your home’s structure, up to $250,000. This includes the foundation, electrical and plumbing systems, furnace, water heater, built-in appliances, permanently installed carpet and certain cabinets.
If rebuilding your home would cost more than $250,000, an NFIP policy won’t cover the full amount. A private policy may offer higher limits.
Contents Coverage
Contents coverage helps protect personal belongings damaged by a covered flood. That includes furniture, clothing, portable appliances, curtains and other household items. NFIP residential policies offer up to $100,000 in contents coverage, separate from building coverage.
NFIP contents coverage pays for covered belongings based on actual cash value, which accounts for depreciation. For example, if a five-year-old couch is damaged in a flood, your payout may reflect what the couch was worth at the time of the damage rather than what it would cost to buy a brand-new replacement.
If you are at a higher flood risk, you should keep a record of your belongings and their values to help claim processes go smoothly.
What Doesn't Flood Insurance Cover?
Under the NFIP, common exclusions and limitations include:
Most basement items: Finished walls, flooring and personal belongings in a basement have limited or no coverage. Essentials like a furnace or water heater are usually covered.
Vehicles: Comprehensive auto insurance may cover flood damage to your car.
Outdoor property: Landscaping, trees, fences, decks, patios and pools aren’t covered.
Temporary housing: Hotel stays, meals and other living costs while your home is being repaired aren’t covered.
Preventable mold or moisture damage: Mold or mildew the owner could have reasonably prevented isn’t covered.
The cause of the water damage also matters. For example, a river overflowing and inundating your home may qualify as a flood loss, while water damage from a burst pipe typically falls under a different type of insurance coverage.
When Is Flood Insurance Required for a Mortgage?
Federal law requires flood insurance when two things are true.
1. The home is in a high-risk flood zone. FEMA calls these Special Flood Hazard Areas. They have at least a 1% chance of flooding in any year and show up on FEMA flood maps as zones that start with A or V (such as Zone A, AE or VE).
2. Your mortgage is government-backed or comes from a federally regulated lender. This includes:
FHA loans
VA loans
USDA loans
Conventional loans sold to Fannie Mae or Freddie Mac
Loans from federally regulated banks and credit unions
That covers nearly every home loan. If the home is in a high-risk flood zone, plan on needing flood insurance.
When coverage is required, it has to equal at least the smallest of three amounts: your loan balance, the home’s insurable value or the NFIP maximum of $250,000. Fannie Mae and Freddie Mac may require more. You’ll keep the policy for as long as you have the loan.
Your lender determines the property’s flood zone early in your homebuying journey. If coverage is required, your policy must be in place by closing day.
A few other things to know:
Lenders can set their own rules. A lender may require flood insurance outside a high-risk zone based on the property’s risk.
Some communities don’t participate in the NFIP. If a high-risk property is in one of these areas, FHA, VA and USDA loans generally aren’t available, and Fannie Mae and Freddie Mac won’t buy the loan.
Flood maps can be challenged. If you think a home was mapped into a high-risk zone by mistake, you can ask FEMA for a Letter of Map Amendment (LOMA). If it’s approved, the federal requirement goes away, though your lender may still require coverage.
Do You Need Flood Insurance If You're Not in a Flood Zone?
No. If you are not located in a high-risk zone, your lender will generally not require you to have a policy, however, every property technically has some level of flood risk, even if it's outside a designated high-risk flood zone. FEMA flood maps help identify areas with elevated risk, but they don't guarantee that properties in other areas won't flood.
Here's how your property's flood zone may affect your insurance needs:
| Property's flood zone | Mortgage insurance requirement | Should you consider coverage? |
|---|---|---|
| Higher-risk area (such as many A or V zones) | Required for mortgages subject to federal flood insurance rules | Yes. Evaluate your risk and compare available policies. |
| Moderate-risk area | Federal requirements don't apply solely because of the property's location | Consider coverage based on the property's individual risk. |
| Lower-risk area | Federal requirements don't apply solely because of the property's location | Voluntary coverage may still make sense. |
Your property's specific flood zone and mortgage requirements will help determine whether coverage is mandatory.
How Does Flood Insurance Work With Your Mortgage Payment?
If you live in a FEMA-required zone, your lender will factor the cost of flood insurance into your total monthly housing expenses, along with your mortgage payment, property taxes, homeowners insurance and other applicable costs. This amount is also included in your debt-to-income ratio (DTI), which compares your monthly debt payments to your income. A higher insurance premium could affect how much home you qualify for.
If your lender requires an escrow account for flood insurance, your monthly mortgage payment will collect money monthly to set aside to pay the premium when it's due. Your mortgage servicer then uses those funds to pay the insurance company.
Not every borrower pays flood insurance through escrow. Depending on your loan and lender's requirements, you may need to pay the insurer directly.
Flood insurance premiums can also change over time. If your premium increases, your monthly escrow contribution and total mortgage payment may increase as well.
Before closing, you should ask your lender whether the premium will be included in escrow. Getting this information early can help you build a realistic housing budget and avoid surprises after you move in.
NFIP vs. Private Flood Insurance
Like homeowners insurance, flood insurance is another cost you can shop around for. You can choose coverage through the National Flood Insurance Program (NFIP) or a private insurer. Private policies may offer different pricing, higher coverage limits or additional benefits.
If your lender requires flood insurance, the estimated cost will appear on your Loan Estimate, but you're free to compare quotes and choose a provider. Just make sure your policy meets your lender's requirements.
How Much Does Flood Insurance Cost?
There's no single price that applies to every homeowner because insurers consider factors related to the building and its flood risk. However, according to a 2026 analysis of National Flood Insurance Program (NFIP) policies, the average cost for a single-family primary residence is about $1,259 per year, or $105 per month. Your actual cost may be higher or lower depending on several factors.
Factors that may affect your premium include:
Location: The property's flood risk and geographic characteristics can influence pricing.
Building characteristics: The home's elevation, foundation type, construction and other features may affect its risk profile.
Replacement cost: The estimated cost to rebuild the home can influence the amount of building coverage needed.
Coverage choices: Your selected coverage limits and deductibles affect the policy's cost.
Is Flood Insurance Worth It If It's Not Required?
Even if your lender doesn't require flood insurance, having a policy may still make sense. Flooding can happen outside designated high-risk zones, and without coverage, you could be responsible for costly repairs and damaged belongings. Federal disaster assistance also isn't guaranteed and may not cover all your losses.
When deciding whether coverage is worth the cost, consider factors that could increase your home's flood risk, including:
Proximity to rivers, streams, lakes or coastal areas
Local drainage problems or a history of flooding
Frequent heavy rainfall
Your home's elevation and the slope of the surrounding property
You can check FEMA's flood maps and ask local officials about past flooding in the area. Comparing the cost of a policy with what you could afford to pay out of pocket can help you decide whether coverage makes sense for your budget.
How to Get Flood Insurance When Buying a Home
If you're purchasing a home, you can take a few steps to determine whether flood insurance is necessary and find appropriate coverage.
Check the property's flood risk. Use FEMA's flood maps to review the property's designated flood zone. You can also ask your real estate agent, lender or local officials about flood history and other risk factors.
Confirm your lender's requirements. Ask whether flood insurance is mandatory for your mortgage and what coverage limits or policy requirements apply.
Compare insurance options. Request quotes from NFIP-participating insurance agents and private insurers. Compare the coverage, exclusions, deductibles and premiums.
Choose an acceptable policy. Select coverage that meets your lender's requirements and fits your financial needs. Confirm the effective date and payment arrangements before closing.
Be aware that flood insurance policies can have a waiting period before coverage takes effect. NFIP policies generally have a 30-day waiting period, but exceptions apply. For example, an exception generally applies when coverage is purchased in connection with making, increasing, extending or renewing a mortgage loan.
Don't assume a new policy will protect you immediately. Confirm the effective date and applicable waiting period with your insurer, especially if you're purchasing a home in a flood-prone area.
What Happens If You Don't Maintain Required Flood Insurance?
If your mortgage requires flood insurance, you're responsible for maintaining the required coverage for as long as that requirement applies.
If your policy lapses or you don't obtain the required coverage, your lender or mortgage servicer may notify you and require you to correct the issue. If you don't, the lender may purchase insurance on your behalf, commonly called lender-placed or force-placed flood insurance.
This coverage is intended to protect the lender's interest in the property. It may cost more than a policy you obtain yourself and may not provide the same protection for your personal belongings.
Maintaining your own acceptable policy can help you avoid coverage gaps and unexpected expenses. If you receive a notice about missing or insufficient flood insurance, contact your mortgage servicer promptly to understand what's required.
The Bottom Line
Flood insurance provides protection that standard homeowners insurance usually doesn't. Depending on your property's flood zone and mortgage, coverage may be mandatory, but even when it's optional, it can offer valuable financial protection.
If you're considering buying a home, request a flood insurance quote before making a final decision. Comparing quotes early can help you understand the potential cost, choose appropriate coverage and determine whether the home fits your budget.
