What a FEMA high-risk flood zone means for your mortgage

If a home sits in a FEMA high-risk flood zone and your mortgage comes from a federally regulated or federally backed lender, which covers most U.S. mortgages, you'll be required to carry flood insurance for the life of the loan. The way to avoid surprises is to check flood exposure before you fall for a house. A Consilium Compare report shows how much of each ZIP code sits in high-risk zones, side by side, for $1.99 at our launch price.

Does flood zone A99 require flood insurance?

Yes, for a federally backed or federally regulated mortgage. Zone A99 is a Special Flood Hazard Area that will be protected by a federal flood-control system still under construction. FEMA does not publish base flood elevations for A99, and the mandatory purchase requirement still applies. See FEMA flood insurance and the A99 section below.

What are lenders' flood insurance requirements?

In a Special Flood Hazard Area, a federally regulated or federally backed lender must require flood insurance for the life of the loan. The coverage amount is generally the lesser of the outstanding loan balance, the maximum available under the National Flood Insurance Program, or the insurable value of the building. FloodSmart explains which zones are high risk. To check flood risk before you buy, start with the ZIP, then confirm the address. Zone letters are explained in FEMA flood zones, including Zone X and Zone AE.

Check the area first

Flood insurance can add a real cost to every monthly payment. A Consilium report shows which of two places carries more flood exposure before you start touring homes, so you can budget for it or steer your search.

When flood insurance is required

• The home is in a high-risk zone, meaning a zone that starts with A or V. FEMA calls these Special Flood Hazard Areas.
• The loan is federally regulated or backed. That includes most banks and FHA, VA, Fannie Mae, and Freddie Mac loans.
• The requirement lasts as long as the loan. If the policy lapses, the lender can buy one for you and add the cost to your payment, usually at a higher price.

Outside high-risk zones, flood insurance is optional, though a lender may still ask for it.

Does flood zone A99 require flood insurance?

Usually, yes. Zone A99 is a high-risk flood area: land with a 1% annual chance of flooding that will be protected by a federal flood-control system (such as a levee) that is under construction and has met specific legal milestones. Because A99 is still a Special Flood Hazard Area, lenders on federally backed or regulated mortgages must require flood insurance, just as in zones A and AE.

What makes A99 different: FEMA maps show no base flood elevations there, and the protection isn't finished yet. Under FEMA's current pricing (Risk Rating 2.0), premiums are based on the individual property's risk rather than the zone letter alone, so get a quote for the exact address before you commit.

What the federal program covers

Most flood policies are written through FEMA's National Flood Insurance Program. For a single-family home, the most it covers is:

If the home is worth more, ask about private flood insurance, which many lenders accept, or extra coverage on top.

Timing and cost

• The 30-day wait: most new flood policies take 30 days to start, but the wait is waived when you buy the policy as part of closing on a mortgage. Set it up before closing day.
• Price varies by house: premiums depend on things like elevation, distance to water, and rebuilding cost. Two homes on the same street can pay very different amounts. Get a quote during your inspection period.

Questions to ask before you close

1. Is the home in a high-risk zone, and does my lender require flood insurance?
2. Does the home have an elevation certificate? It can lower your premium.
3. Has the current owner had a flood policy, and what does it cost?
4. Have there been past flood claims on the property?
