Quick answer
How much is flood insurance in Texas? There is no one price. FEMA rates each flood policy on that house's own risk: how close it is to water, how high it sits, its first-floor height, and what it would cost to rebuild. On a Texas beach house, flood is only one bill. Windstorm coverage, property tax without a homestead exemption, and salt-air upkeep all add up, so get real quotes on the real address before you buy or decide to hold.
How much is flood insurance in Texas? It is the first question we hear from owners and buyers at the coast, and the honest answer is "it depends on the house." We are Carter Signature Properties, the largest brokerage on the island, and we help owners in Surfside Beach, Treasure Island, Freeport, and the rest of Brazoria County figure out what a beach house really costs to keep. Here is the plain-English version.
Why is flood insurance in Texas cost so different from house to house?
Since FEMA moved to its current rating method (called Risk Rating 2.0), each National Flood Insurance Program (NFIP) policy is priced on the home's own flood risk. FEMA's FloodSmart site lists the main factors:
- Distance to a water source
- Elevation and first-floor height
- The cost to rebuild the home
- The deductibles you choose
Plain-English takeaway: a raised house on pilings and a slab house two streets back can get very different quotes. Your neighbor's number is not your number.
Two more facts to know. FEMA's NFIP caps residential coverage at $250,000 for the building and $100,000 for contents, and new policies usually have a 30-day waiting period (FEMA and TWIA both point this out). Plain-English takeaway: if your home is worth more than the cap, ask about extra coverage, and never wait for a storm in the forecast to buy a policy.

Does TWIA require flood insurance on a beach house?
Sometimes. The Texas Windstorm Insurance Association (TWIA) says it requires flood insurance only when all three of these are true:
- Any part of the property is in a V zone (V, VE, or V1-V30) on FEMA's flood map.
- NFIP flood coverage is available for the property.
- The structure was built, altered, remodeled, or enlarged after September 1, 2009.
TWIA also lists a windstorm Certificate of Compliance (form WPI-8 or WPI-8-E, issued by the Texas Department of Insurance) as an eligibility requirement. Plain-English takeaway: before you buy, ask for the windstorm certificate and the flood zone. Before you sell, find yours now. Buyers ask for them early.

What does it really cost to own a Texas beach house?
Think of it as a monthly bill with several lines. We don't put dollar amounts here because every house is different, but here is the checklist and where to find your real number:
Cost | Where to get your real number |
|---|---|
Flood insurance | A quote on the exact address (call Anthony at Connect Insurance) |
Windstorm insurance | A quote, plus the home's WPI-8 certificate |
Homeowners insurance | Your declarations page |
Property tax | Brazoria Central Appraisal District account and your tax bill |
HOA or condo dues | Your HOA statement |
Utilities | Last 12 months of bills (they still run when it's empty) |
Salt-air upkeep | AC, paint, metal hardware, pilings, and decks wear faster at the beach |
Management or cleaning | Your rental manager's statements, if you rent it out |
What is the Brazoria County property tax rate on a second home?
There isn't just one. Your Brazoria County property tax rate is the total of every taxing unit on your bill: the county, your city, your school district, and others. The bigger surprise for second-home owners is the homestead exemption. The Texas Tribune reported on October 20, 2026 that homeowners can't claim more than one primary residence, and that the school district homestead exemption is now $140,000. Plain-English takeaway: a beach house that isn't your main home usually pays tax on its full value, with no homestead exemption and no 10% homestead cap.

Beach town or inland: how the costs change across Brazoria County
- Surfside Beach and Treasure Island: right on the Gulf, so ask about flood zone, windstorm certificate, and elevation first.
- Freeport: mix of older homes and newer builds. Check flood maps street by street.
- Lake Jackson, Clute, and Angleton: inland, but flood risk still varies by street. Look up the address on FEMA's Flood Map Service Center.
Thinking about buying a beach house? Ask for these 5 things
- The flood zone and any elevation certificate
- The windstorm certificate (WPI-8 or WPI-8-E)
- Current insurance declarations pages
- The last property tax bill
- Rental income and expense records, if it's been rented

Hold or sell? The one-number test
Add up the monthly lines in the table. Then compare that number with the real money the house brings in after every expense. If the house costs more to keep than it gives back, and you rarely use it, it may be time to talk about selling. If it pays its way and you love it, keep it. Both are fine answers. If you live far away, our guide on how to sell a house from out of state walks through every step, and cash offer vs. listing your Texas house shows what you really keep.

Frequently asked questions
How much is flood insurance in Texas for a beach house?
It depends on the house. FEMA prices each National Flood Insurance Program policy on that home's own flood risk, including distance to water, elevation, first-floor height, and the cost to rebuild, so two beach houses on the same street can get very different quotes. For insurance quotes or questions, call Anthony at Connect Insurance at 214-215-0956.
Does TWIA require flood insurance?
Sometimes. TWIA says it requires flood insurance only when all three apply: part of the property is in a V zone (V, VE, or V1-V30), NFIP flood coverage is available, and the structure was built, altered, remodeled, or enlarged after September 1, 2009.
How long does it take for flood insurance to start in Texas?
New NFIP flood policies usually have a 30-day waiting period, according to FEMA and TWIA. That means you can't wait for a storm in the forecast and then buy coverage.
Can I get a homestead exemption on a Texas beach house?
Only if it is your primary home. The Texas Tribune reported on October 20, 2026 that homeowners may not claim more than one primary residence, so a second home or rental at the coast usually pays property tax without the homestead exemption.
What is a Texas windstorm certificate?
It is a Certificate of Compliance (form WPI-8 or WPI-8-E) issued by the Texas Department of Insurance. It shows the work meets building codes for high winds and hail, and TWIA lists it as an eligibility requirement.
