The wet beach
From the water up to the mean high-tide line. This is state-owned and always public.
Coast / Who owns the beach
The answer is surprising, and very Texas. You have a constitutional right to the Gulf beach - with some real limits worth understanding. Here's the plain version.
Picture three zones, from the water up:
From the water up to the mean high-tide line. This is state-owned and always public.
From the high-tide line up to the natural line of vegetation (where the grass and plants start). This may be privately owned, but the public still has the right to use it - so even on private dry sand, you can generally walk, sit, and play.
This is private property.
In plain terms, the line of vegetation marks the boundary: everything seaward of it is open to you. (The Open Beaches Act public easement actually runs all the way from the mean low-tide line up to the vegetation line.)
The catch
Get there the right way: Use public access points - public road ends, marked beach access points, and parks - rather than crossing someone's yard to reach the sand.
Storms move the line, and the law is complex: Hurricanes and erosion shift the vegetation and tide lines. After a 2012 Texas Supreme Court case (Severance v. Patterson), the public's beach easement does NOT automatically jump landward onto previously private land after a sudden storm - though it can still shift with gradual erosion. What a beachfront owner may rebuild after a storm is governed by state law and the GLO.
This is general orientation, not legal advice. Whether a specific stretch is public, and what an owner can build, are fact-specific and sometimes contested - so check with the GLO, and for a real dispute, talk to an attorney.
Official sources
Beach access comes from the Texas Open Beaches Act and a 2009 constitutional amendment, enforced by the GLO and the Attorney General. We explain the doctrine; we don't rule on a specific stretch or dispute.
