Mortgage Required Flood Insurance: When Is It Required by Lenders?
Learn about mortgage required flood insurance and when lenders require it, so you can protect your property and comply with lender flood insurance rules.

When buying a property, particularly in flood-prone areas, there is more to consider than just monthly payments and interest rates. One critical but sometimes ignored requirement is flood insurance. If your new home is in a high-risk flood zone, lenders may legally require you to obtain flood insurance before closing the transaction and maintain it for the life of the loan.
Understanding flood insurance requirements and why you need it can save you from delays, unexpected expenses, and even loan denials. As part of this blog, we'll discuss how homeowners can stay compliant and protected by flood insurance, when it's required, and when it's not.
What Is Mortgage Required Flood Insurance?
Mortgage required flood insurance is a type of insurance policy that protects against physical damage to property and possessions caused by flooding. While ordinary home insurance often excludes flood damage, this coverage ensures that flood-related losses and repairs are covered.
From the lender's perspective, this insurance protects their investment if the property is significantly damaged or destroyed by flooding. It offers the homeowner financial security and peace of mind in flood-prone areas.
When do Lenders require Flood Insurance?
Lenders don't always require flood insurance, but sometimes they do. Here is when it becomes a legal and financial need:
- If the property is in a Special Flood Hazard Area (SFHA), FEMA says these are high-risk areas where there is at least a 1% chance of flooding in any given year. Homes in these areas are much more likely to experience a flood, so lenders have to follow regulator guidance and rules.
- When a federally regulated or insured lender provides a mortgage, flood insurance is mandatory for properties in SFHAs. This is also the case if your loan is through Fannie Mae, Freddie Mac, FHA, or the VA.
Failing to purchase a policy before closing could result in loan denial or closing delays.
Laws and Regulations Involved
The federal government plays a key role in regulating mortgage required flood insurance requirements. Two key laws enforce these rules:
- Flood Disaster Protection Act of 1973: This act requires flood insurance for any property in an SFHA with a federally backed mortgage.
- National Flood Insurance Reform Act of 1994: Strengthens lender obligations to ensure coverage is in place and maintained.
How to Know If You Need Flood Insurance
The most reliable way to find out is by checking your flood zone using the FEMA Flood Map Service Center. You’ll need your property’s address to access updated flood hazard maps. These maps determine whether your home is in an SFHA, which triggers the lender’s insurance requirement.
During the mortgage approval process, the lender will also order a flood zone determination report. If your residential property or commercial property is within a high-risk area, they’ll notify you that insurance is required.
What Happens If You Don’t Have It?
Choosing to skip flood insurance when it’s required (or letting your policy lapse) can lead to serious consequences:
If you’re required to have flood insurance by the mortgage lender and fail to purchase or maintain it, the consequences can be both immediate and costly. For properties located in FEMA-designated Special Flood Hazard Areas (SFHAs), federally regulated or insured lenders are legally obligated to ensure that a valid flood insurance policy is in place throughout the life of the loan.
The first and most common consequence of not carrying flood insurance when required is loan denial or delay at closing. If the insurance isn’t secured by the time of final approval, your mortgage lender may postpone or even cancel the closing, regardless of your credit score or financial standing. For homebuyers eager to move in, this can be frustrating and costly.
After your mortgage has been issued If your property is later remapped into a high-risk flood zone your lender will advise you that a flood insurance policy must be obtained as a result of the flood zone change. If evidence of flood insurance isn’t provided your lender has the right to purchase force-placed flood insurance to protect their interest in the property. In addition, if your policy lapses after the mortgage has been issued, again, your lender has the right to purchase force-placed flood insurance. This type of policy is generally much more expensive than a standard NFIP or private insurance policy and typically offers limited coverage to only cover the outstanding balance of the loan and their interest in the property. You’ll be responsible for the cost of this policy, as it will be added to your escrow and monthly mortgage payment without the opportunity to shop around for better rates. Worse still, if a flood occurs and you don't have mortgage required flood insurance, you'll be fully responsible for all repair and rebuilding costs. Unlike fire or theft, flooding is not covered under most standard homeowners' insurance policies. This could leave you paying tens of thousands of dollars out of pocket, especially if both the structure and contents of your home are damaged.
Optional Flood Insurance: Should You Get It Anyway?
Even if you’re outside an SFHA and your lender doesn’t require coverage, buying flood insurance might still be a smart move. Flooding isn’t just a coastal or riverfront issue. Heavy rain, snowmelt, hurricanes, or even construction in your area can change water flow and increase flood risk.
According to FEMA, more than 40% of flood claims come from low-to-moderate-risk zones. With climate change causing unpredictable weather patterns, it’s wise to consider optional coverage.
How to Get a Quote or Policy
There are two main places where you can get flood insurance:
- NFIP stands for the National Flood Insurance Program. NFIP policies are the same in all 22,600 participating communities in the U.S. and are backed by the government.
- Private Flood Insurance Companies: These might have more flexible coverage options, higher limits, or extra benefits like covering temporary living costs.
To optimize rates and coverage for your property, compare quotes from both sources. Most private flood products are accepted by lenders, but your lender may need to approve the private flood insurance company.
Final Thoughts
Mortgage required flood insurance isn’t just a legal requirement; it’s an essential layer of protection for your home and finances. Lenders require it to protect their investments, but as a homeowner, you benefit from being financially prepared for the unexpected.
Whether mandated or optional, flood insurance can be the difference between complete recovery and financial ruin following a calamity. Don't wait for the storm clouds to build; check your flood zone, review your mortgage terms, and get the necessary coverage now.
