Flood Insurance When Buying a Home in Texas: 2026 Guide

If you are thinking about flood insurance when buying a home in Texas, start early in your contract, not in closing week. If the home sits in a high-risk flood zone and your mortgage is federally regulated or federally backed, you generally need flood coverage before you can close. Even when it isn’t required, it may be worth considering, because a standard homeowners policy usually doesn’t cover flood damage. This year there is a second reason to move early: the National Flood Insurance Program (NFIP) can write new policies only through December 11, 2026, unless Congress extends it.

TL;DR

A home in a FEMA Special Flood Hazard Area (zones starting with A or V) generally needs flood insurance for the life of a federally regulated or federally backed mortgage.

Most Texas resale sellers must disclose flood zones, past flooding and past flood claims, but that form does not apply to a never-occupied new home.

Check the FEMA flood map and get a quote during your option period, before you are locked in.

NFIP coverage usually starts after 30 days, but there is no wait when you buy it in connection with making a mortgage loan.

Closing near December 11? Ask about taking over the seller’s policy, compare private flood insurance and get your mortgage company’s plan in writing.

Why flood insurance is in the news

On October 20, 2026, FEMA launched a way to buy an NFIP policy completely online at FloodSmart.gov. It works in almost 22,700 communities that take part in the program. You enter basic building information, get a quote, and then buy online or share it with an insurance agent. FEMA calls floods the most common and costliest natural disaster in the United States.

The deadline matters too. According to the Congressional Research Service, Congress authorized the NFIP through December 11, 2026. Unless Congress acts, its authority to issue new flood insurance contracts expires then. Policies already in place would continue until the end of their one-year term. The program lapsed from October 1 through November 12, 2025, and again from February 1 to February 3, 2026. CRS notes that in past lapses, borrowers could not get NFIP coverage to close loans on homes in high-risk areas until the program was reauthorized.

A Government Accountability Office report released October 1, GAO-27-108012, adds context. As of April 2026, 86% of high-risk properties nationwide lacked NFIP coverage. GAO also found that FEMA’s maps don’t capture all flood risk, especially from heavy rainfall, and that about 13 million high-risk properties sit outside mapped high-risk zones.

Does your home need flood insurance?

It depends on two things: your flood zone and your loan type.

A Special Flood Hazard Area (SFHA) is land FEMA maps as having at least a 1% chance of flooding in any year. On the map, these zones start with A or V (for example, A, AE, AO, AH, VE). You may hear this called the “100-year floodplain.” That name does not mean a flood happens only once a century.

Under the federal flood insurance purchase requirement, a loan from a federally regulated institution, or a loan backed by a federal agency or Fannie Mae or Freddie Mac, on a building in an SFHA in a participating community must carry flood insurance. That covers most conventional, FHA, VA, and USDA home loans. For federally regulated institutions, the rule says the coverage must last for the term of the loan and be at least the lesser of the outstanding principal balance or the maximum coverage available. FHA’s rule uses the lowest of the home’s replacement cost, the maximum NFIP coverage, or the loan balance.

For a home, NFIP building coverage goes up to $250,000 and contents coverage up to $100,000, according to FloodSmart. Flood insurance covers the building and your belongings, not the land.

When the home is in an SFHA, a federally regulated institution must give you a written notice that the property is in a special flood hazard area within a reasonable time before closing. The notice also says private flood insurance may be available and encourages you to compare coverage, deductibles, and premiums. A mortgage company can also set its own requirements, so ask your loan officer early whether the flood determination is done and what the company needs.

What the Texas seller’s disclosure tells you

For most resale homes with one dwelling unit, Texas Property Code Section 5.008 requires the seller to give you a written disclosure notice on or before the effective date of the contract. The flood questions ask whether the seller is aware of:

Present flood insurance coverage on the property.
Previous flooding from a reservoir release or breach, or water getting into a structure from a natural flood.
Whether the property is wholly or partly in a 100-year floodplain, a 500-year floodplain (shaded Zone X), a floodway, a flood pool or a reservoir.
Any flood damage claim with any insurance provider, including the NFIP.
Any FEMA or U.S. Small Business Administration assistance for flood damage.

Read every answer and ask follow-up questions about “unknown” answers, drainage repairs, and past claims. If the seller didn’t provide the notice before the contract took effect, the law lets the buyer terminate the contract for any reason within seven days of receiving it.

New construction: you have to ask

The seller’s disclosure law does not apply to a new home that has never been lived in. If you are buying new construction, ask the builder for the flood zone, any elevation certificate, and how the lot and neighborhood drain. A brand-new house doesn’t prove the lot has low flood risk.

How to check flood risk during your option period

Many Texas resale contracts include a short option period. That is the best time to do flood homework, while you still have choices.

Look up the address. Search the home on FEMA’s Flood Map Service Center and note the zone where the house itself sits.
Ask for an elevation certificate. FloodSmart says you don’t need one to buy flood insurance, but it can help you pay less. Ask the seller, builder, or insurance agent if one exists.
Ask about water history. Ask about past water in the home or garage, drainage work, and any flood claims or FEMA assistance.
Get a real quote. Have an insurance agent quote the actual address, or use the new online tool at FloodSmart.gov. Ask what is covered, what the deductibles are, and the start date.

Add the premium to your budget as soon as you have a quote. Our guide on how much house you can afford in Texas walks through the full monthly picture. If flood insurance is required on a residential loan made on or after January 1, 2016, a federally regulated institution generally must collect the premium through escrow, with some exceptions. The first year’s premium is often part of your cash to close.

NFIP or private flood insurance?

The Texas Department of Insurance says most Texans with flood insurance have an NFIP policy, but you can also buy flood coverage from a private insurance company. TDI suggests shopping around, asking whether the seller has an NFIP policy that can transfer to you, and confirming the coverage your mortgage company requires.

A private policy can count toward the requirement. Federally regulated institutions must accept a private flood policy that meets the federal definition and coverage amount. For FHA loans, the mortgage company may accept a qualifying private policy. GAO reported that private policies made up 14% of all flood policies in 2025. Coverage, deductibles, and exclusions vary, so send the policy to your loan officer before closing week.

The 30-day wait and your closing date

NFIP coverage generally starts 30 days after you buy it. Federal law makes an exception when you purchase it in connection with making, increasing, extending, or renewing a loan. FloodSmart also lists a one-day wait if your property was newly mapped into a high-risk zone and you buy within 12 months of the map change. For a home purchase, that usually means coverage can start at closing. Still, your agent needs time to quote and issue the policy, and your mortgage company needs time to review it.

Closing in December? Plan for the December 11 date

Congress has often extended the NFIP before a deadline, and in most past lapses it restored the program retroactively. But that does not prevent delays during a lapse. The National Association of REALTORS explains what happens if the program lapses:

The NFIP cannot issue new or renewal policies until it is reauthorized.
Existing policies stay in effect until they expire, including a 30-day grace period.
The seller’s NFIP policy may be assigned to the buyer, so the buyer doesn’t need a new policy.
Private flood insurance is not affected.
Most federal regulators suspend the purchase requirement during a lapse and leave it to each mortgage company to decide whether to close loans in high-risk zones.

If you could close on or after mid-December, get your flood quote now, ask the seller’s agent whether the seller has an NFIP policy that could be assigned, get a private flood quote as a backup, and ask your loan officer in writing how the mortgage company would handle your closing if the NFIP lapses.

Flood insurance do’s and don’ts

Do and avoid checklist for flood insurance when buying a Texas home: do check the FEMA flood map early, read the seller's flood disclosures, get a quote during the option period and get your mortgage company's lapse plan in writing; avoid assuming homeowners insurance covers flood, assuming zone X means no risk, waiting until closing week and buying a policy before your loan officer reviews it

Do

Look up the flood zone as soon as you are under contract.
Read the seller’s flood answers and ask follow-up questions.
Get a flood quote during your option period.
Compare NFIP and private coverage, deductibles, and exclusions.
Send the policy to your loan officer before closing week.
Ask in writing how a December 11 lapse would affect your closing.

Avoid

Assuming your homeowners policy covers flood damage.
Assuming a home outside a high-risk zone has no flood risk.
Waiting until the Closing Disclosure to think about flood insurance.
Treating a new home as automatically low risk.
Buying a policy before confirming it meets your mortgage company’s requirements.

FAQ

Is flood insurance required on every Texas home purchase?

No. It is generally required when the building is in a Special Flood Hazard Area, and the mortgage is federally regulated or federally backed. A mortgage company can have its own requirements, and flood risk can exist outside mapped high-risk zones.

Does homeowners insurance cover flooding?

Usually not. FloodSmart says most homeowners insurance does not cover flood damage, so flood coverage is a separate policy.

Can I use private flood insurance instead of an NFIP policy?

Often, yes, if the policy meets the federal definition and your mortgage company accepts it. Have your loan officer review it early.

Will I have to wait 30 days for coverage?

Usually not for a purchase. Federal law waives the 30-day wait when you buy NFIP coverage in connection with a loan. Confirm the start date with your insurance agent.

What happens to my closing if the NFIP lapses on December 11?

New NFIP policies could not be issued until Congress acts. Options include assigning the seller’s existing NFIP policy or buying private flood insurance, and some mortgage companies may decide on a case-by-case basis. Ask your loan officer for the plan in writing.
