If you take out a mortgage on a house that is in a high-risk flood area, your lender will likely require you to purchase flood insurance. If your mortgage is backed by the government or secured through a financial institution like Fannie Mae and your home is in a special flood hazard area (SFHA), you’re actually required by law to have flood insurance.
The amount of flood insurance you need on top of your homeowners insurance will depend on your lender and what type of mortgage you have. When setting your flood insurance limits, don’t assume your lender’s minimum coverage requirements will be enough. Aim to have enough coverage to pay for a full rebuild of your house and to replace all of your personal belongings.
Flood insurance is usually only required if you live in a high-risk flood area and you have a mortgage on the home.
Your lender will have their own flood insurance coverage limit requirements, but you should generally aim to have enough coverage to pay for a rebuild of the house.
Flood insurance is traditionally purchased through private insurers but backed by the federal government’s National Flood Insurance Program (NFIP). However, many homeowners are pivoting to the private flood insurance market for lower-cost and more comprehensive coverage.
Your minimum flood insurance requirements will depend on the type of mortgage you have on the home. Loans secured by Fannie Mae and Freddie Mac, for example, are subject to the following minimum flood insurance requirements (whichever is lowest of the three):
The outstanding principal balance of the loan
The maximum amount available under the NFIP for the type of structure you own. For homes, that amount is $250,000
The insurable value of the property, or the home’s rebuild cost
Keep in mind that there is a good chance your actual flood insurance needs will differ from the coverage minimums required by your lender. The following section will guide you through how to select the right amount of coverage.
If you live in a high-risk flood area, you’ll want to gauge how much flood insurance you’d need to rebuild your house from the ground up and replace all of your personal property. Prior to setting your coverage amounts, find out the following:
The amount it would cost to rebuild your home. The property coverage in your policy should be equal to the home’s replacement value, not its market value or the outstanding balance of the mortgage principal. The dwelling coverage limit in your homeowners insurance policy is a good barometer of how much flood insurance you’ll need. For something more precise, contact a certified appraiser who specializes in replacement cost appraisals.
The amount it would cost to replace your belongings. Be sure to evaluate and add up the value of your personal belongings. Setting up ahome inventory with property descriptions and prices is an effective and convenient way to figure out the value of everything you own.
Your flood insurance needs are going to hinge largely on which flood zone you’re in
A home in a high-risk flood zone may be best served by a more comprehensive private flood insurance policy with higher coverage limits than the more limited NFIP flood policy.

The National Flood Insurance Program (NFIP) has long been the standard flood insurance provider on the market, and still accounts for roughly 95% of active policies. With NFIP flood insurance, private insurance companies sell the policies and settle claims on behalf of the federal government, but the government is responsible for claim payouts.
But this policy isn’t ideal for high-value homes (exceeding $250,000 in rebuild value) due to the program’s strict coverage maximums. For additional protection, consider something like supplemental excess flood insurance or a private flood insurance policy.
|Coverages and guidelines||NFIP||Private flood insurance|
|Buildings coverage||Maximum: $250,000 (replacement value)||Maximum: $2,000,000 or higher (replacement value)|
|Contents coverage||Maximum: $100,000 (actual cash value)||Maximum: $1,000,000 (replacement value)|
|Additional living expenses||N/A||Maximum: $50,000|
|Debris removal||Maximum: $250,000||Maximum: $500,000 or buildings coverage maximum (whichever is less)|
|Loss avoidance coverage||$1,000||$1,000|
|Deductible||Minimum: $1,000||Minimum: $500|
|Elevation certificate||Required||Not required|
|Waiting period||30 days||As little as 10-14 days|
|Accepted by mortgages||Yes||Yes|
|Availability||All 50 states||May be limited in higher-risk areas|
It’s becoming increasingly common for private companies to write and service their own flood insurance
Private flood insurance is a good alternative to NFIP coverage for a few reasons: building property coverage limits can be higher, coverage for personal belongings is more comprehensive, and private flood insurance is often cheaper than NFIP coverage.
Excess flood insurance works like this: Let’s say you maxed out the full $250,000 in building property coverage, but your home’s actual rebuild value is $350,000. That’s a $100,000 insurance gap that you’ll need to pay out of your own pocket in the event your home is destroyed in a flood. Excess flood insurance essentially fills that gap in coverage.
In addition to increasing your buildings and contents limits, excess flood insurance may also include additional protection like additional living expenses coverage to pay for added living costs like meals and hotel stays after a flood evacuation. If you have coverage through the NFIP and your home is in a particularly high-risk area, excess flood insurance is a smart option.
Flood insurance can be prohibitively expensive in the most high-risk areas, so if you’re wondering how you can minimize or opt out of flood insurance requirements, you’re probably not alone. There are a few things you can do to lower the cost of coverage or potentially become exempt from flood insurance requirements.
If you believe the NFIP incorrectly determined that your home was in a Special Flood Hazard Area, you can submit an application to FEMA to request a change in flood zone designation.
Once FEMA reviews the request, they will issue a response either denying or accepting the map change request, also known as a Letter of Map Amendment (LOMA). If the map revision is approved, be sure to show this document to your lender to have the flood insurance requirement removed.
Private flood insurance is often cheaper than NFIP coverage, not to mention the coverage itself is superior. If you’re looking for cheaper insurance alternatives, your best bet as always is to re-shop your insurance.
If you have a government-backed or conventional mortgage on your home, your lender is typically required by law to require flood insurance. That isn’t the case, however, with home loans that aren’t required to meet Fannie and Freddie guidelines, or nonconforming mortgages.
If you’re looking for a mortgage with less strict standards and insurance requirements, or you’re planning on refinancing anyway, look into a nonconforming mortgage with a private lender.
Flooding impacts almost every county in the U.S., so every home that is at or below the base flood elevation (BFE) probably should have flood insurance. 
There are a number of different flood risk areas, but they’re generally broken up into three distinct categories: high-risk areas, moderate- to low-risk areas, and undetermined areas.
High-risk areas. A high-risk flood zone or Special Flood Hazard Area has at least a 1% chance of flooding each year. Homeowners in these areas with a federally regulated or insured mortgage are required to buy flood insurance. If by chance you have a nonconforming/unregulated mortgage that doesn’t have the flood insurance requirement, you’re going to want coverage anyway. Homes in high-risk flood zones have a 1 in 4 chance of flooding over the course of a 30-year mortgage, according to FEMA.
Moderate- to low-risk areas. Moderate to low-risk areas have less than a 1% chance of flooding each year, but the possibility is still there. Federally-regulated lenders can’t require flood insurance in these areas, but it’s still highly recommended.
Undetermined-risk areas. These are areas that haven’t been mapped out by FEMA. This creates a degree of uncertainty around the home’s risk, for both residents and insurance companies. If you live in an undetermined risk area, consult your lender or local floodplain administrator for more information about flood risk in the community.
Mortgage lenders have a financial interest in protecting your property from catastrophic events, including tornadoes, wildfires, and flooding. While just about every lender requires homeowners insurance, flood insurance is usually only mandatory if your home is in a high-risk flood zone.
A flood insurance policy through the NFIP costs around $700 annually, but the cost of your own policy will depend on which flood zone you’re in and the BFE of your property.
Short term, your best bet may be to shop around and check prices with private flood insurers. Long term, consider retrofitting your home. Raising your home’s elevation or moving systems and utilities (like water heaters, electrical and plumbing) above the BFE can all result in lower rates. Filling in crawl spaces and basements can also lead to lower flood insurance premiums.
