Selling Coastal Property in Texas: Coastal Addenda, Windstorm and Flood

What agents need to track on Texas coastal transactions: the coastal addenda, windstorm coverage and certificates, flood insurance and elevation certificates, and rental properties.

Selling Coastal Property in Texas: Coastal Addenda, Windstorm and Flood

Coastal files look like any other Texas resale until you get into the details. Then there are extra notices the statute requires, insurance that can’t be bound without a certificate, flood questions the lender will ask whether or not the seller did, and, often, a buyer who’s closing on a rental from three hours away.

None of it is hard. It just has to be started on day one instead of discovered the week of closing. Here’s what we track on Galveston, Bolivar Peninsula and Gulf Coast files.

The coastal addenda

Two statutory notices apply to coastal property in Texas, and TREC promulgates an addendum for each: the Addendum for Coastal Area Property and the Addendum for Property Located Seaward of the Gulf Intracoastal Waterway.

  • Coastal area property. When the property adjoins and shares a boundary with tidally influenced waters, the Texas Natural Resources Code requires a notice about coastal area property to be included in the contract. The TREC resale contract’s statutory notices (Paragraph 6.E) point you to it.
  • Property seaward of the Gulf Intracoastal Waterway. Property located seaward of the GIWW needs a separate notice covering the public’s right to use the beach and the effects of erosion. On the island and the peninsula, that’s a lot of listings.

Because these are required by statute, we confirm them at intake, when we’re reading the executed contract, not at the closing table. If an addendum is missing, the time to fix it is before anyone has relied on the contract.

Windstorm coverage and certificates

Along the Texas coast, standard homeowner’s policies often exclude wind and hail, so coverage comes from the Texas Windstorm Insurance Association (TWIA) or a private carrier.

What trips files up is the certificate of compliance. The Texas Department of Insurance issues it after a windstorm inspection shows the structure, or a later repair, meets the windstorm building code. Coverage can depend on it. If the house was re-roofed, added onto or repaired without one, the buyer’s agent and the insurance agent need to know now, not five days before funding.

What we track:

  • Whether the seller has windstorm certificates for the home and any later work
  • The buyer’s windstorm quote and binder, alongside the homeowner’s policy
  • The lender’s insurance requirements, so the binder matches what underwriting needs

Flood: disclosures, elevation and insurance

Flood comes up on nearly every coastal file.

  • Seller’s disclosure. The Texas seller’s disclosure asks about flood insurance, prior flooding, flood claims and whether the property is in a floodplain. Make sure it’s complete and delivered.
  • Elevation certificate. It drives the flood premium. If the seller has one, get it into the file early. If not, the buyer may want one ordered.
  • Flood insurance. In a special flood hazard area with a federally backed or regulated loan, the lender will require it. A new NFIP policy normally has a waiting period, but a policy bought in connection with making the loan can take effect at closing, so coordinate the timing with the lender.
  • Rentals. Texas landlords have to give tenants a flood disclosure in residential leases, so if there’s a long-term tenant, ask for the lease and its disclosure. TREC publishes a Landlord’s Floodplain and Flood Notice for this.

Rental properties and out-of-town buyers

A lot of Galveston buyers are buying a second home or a rental, and many of them don’t live nearby.

  • Existing bookings. Short-term rentals often have guest reservations on the calendar past closing. The contract should say what happens to them and to any deposits.
  • Management agreements. If a rental manager is in place, find out whether the agreement transfers or ends, and on what notice.
  • Registration and taxes. Rentals may carry local registration and hotel occupancy tax accounts. In the City of Galveston, short-term rentals register through the Park Board. The buyer will need their own.
  • Remote signing. Out-of-town buyers often sign by mail-away or remote online notarization. Line it up with the title company early, especially if a spouse or entity is signing too.

A coastal checklist

At intake on a coastal file, we add these to the standard contract-to-close checklist:

  1. Coastal area and seaward-of-the-GIWW addenda: needed? signed?
  2. Windstorm certificates for the home and later work
  3. Windstorm and homeowner’s quotes and binders
  4. Elevation certificate and flood quote
  5. Seller’s disclosure flood answers complete
  6. Leases, flood disclosure to tenants, bookings, management agreement
  7. Remote signing plan with the title company

If you work coastal files and want someone running that list for you, that’s what we do on every Galveston and Houston-area file.

Frequently Asked Questions

When does a Texas contract need the coastal area addendum?
When the property adjoins tidally influenced waters, Texas law requires a notice about coastal area property to be part of the contract, and TREC promulgates an addendum for it. Property seaward of the Gulf Intracoastal Waterway needs a separate addendum covering beach access and erosion. Check both at intake, before the contract is signed.
What is a windstorm certificate in Texas?
It’s the certificate of compliance the Texas Department of Insurance issues after a windstorm inspection shows a structure (or repair) was built to the windstorm building code. In the coastal counties it’s often needed to get windstorm coverage, so ask for it at the start of the file.
Does a buyer need flood insurance to close on a Galveston home?
If the home is in a special flood hazard area and the buyer has a federally backed or regulated mortgage, the lender will require flood insurance. Many coastal buyers carry it anyway. Get the elevation certificate and a quote early so the premium doesn’t surprise anyone at closing.
Are there extra steps when the property is a short-term rental?
Usually. Existing guest bookings, rental management agreements and local registration or hotel occupancy tax accounts need to be addressed in the contract and handed over or closed out. In the City of Galveston, short-term rentals register through the Park Board.
