Waterfront property on Lake LBJ or Lake Marble Falls is a different purchase than a home in town, and most of the differences come down to one thing: the Lower Colorado River Authority (LCRA) controls the shoreline, not the county and not the HOA. Before you write an offer on a lake lot, it’s worth understanding what that actually means for what you can build, what you can keep, and what it costs to own.
TLDR
- LCRA, not the city or county, sets the rules for docks, boathouses, and shoreline changes on the Highland Lakes.
- Most residential docks don’t need an LCRA permit, but they do need to meet LCRA’s safety standards, and those standards vary by lake.
- Lake LBJ and Lake Marble Falls are both kept within a narrow, fairly steady operating range in normal conditions, unlike Lake Buchanan and Lake Travis, which the LCRA manages for flood control and water supply and which fluctuate a lot more.
- Waterfront access doesn’t always mean full water rights. Check whether access is deeded or shared before you assume anything.
- HOA or POA rules stack on top of LCRA rules and can be more restrictive.
Existing Docks and Structures Aren’t Automatically Fine
The most common mistake I see buyers make on a lakefront listing is assuming that whatever’s already built is legal and stays that way. LCRA sets Safety Standards for Residential Docks on the Highland Lakes covering flotation, lighting, anchoring, and how far a dock can extend from the shoreline. On Lake LBJ that maximum is 50 feet from shore; on Lake Marble Falls it’s 35 feet, with some allowance in shallow coves. A dock built years ago under different rules, or built without ever following them, can become the new owner’s problem to fix.
Here’s the part that surprises people: LCRA doesn’t require a permit or fee for a typical residential dock under 1,500 square feet of water surface area. Most single-family docks fall under that. What does require a permit is anything bigger, shared community docks, or a marina, under LCRA’s Highland Lakes Marina Ordinance. So the permit question isn’t really “do I need LCRA’s sign-off,” it’s “does this dock actually meet the safety standards,” which is a different thing to verify before you close.
Lake LBJ and Lake Marble Falls Behave More Alike Than People Assume
Both lakes are what LCRA calls pass-through lakes, along with Inks Lake and Lake Austin. They’re operated within a fairly narrow band under normal conditions rather than swinging with rainfall the way Lake Buchanan and Lake Travis do, since those two are managed as flood-control and water-supply reservoirs. That’s genuinely useful for a lake-house buyer: a dock that works in June should generally still work in December on either lake. It’s not an absolute guarantee, though. Even the pass-through lakes can rise above their normal range during a flood event, so “steady” isn’t the same as “never changes.”
Water Access Isn’t Always the Same as Water Rights
Some lots look like true waterfront in photos but only carry a shared or easement access point rather than a deeded stretch of shoreline. That distinction matters for how you can actually use the water and for resale value down the road. If a listing mentions a community boat ramp or shared dock instead of private shoreline, ask specifically what the deed says before you assume you’re buying the same thing as the lot next door.
HOA and POA Rules Layer on Top of LCRA’s
Plenty of lake communities on Marble Falls and LBJ sit inside an HOA or POA with its own rules on boat lifts, dock style, fencing, or exterior colors, and those rules aren’t always in the public listing. I’ve seen buyers assume they could add a second story or a bigger dock, only to find out the neighborhood association had already said no. It’s worth pulling the HOA or POA documents before you fall in love with a specific improvement plan.
Check the Floodplain Before You Check the View
A lakefront lot can still sit partly or fully in a mapped floodplain, and that affects insurance cost, what you’re allowed to rebuild if something happens, and how a lender treats the loan. Get an actual insurance quote on the specific property, not a general estimate for the area, before you finalize an offer. It’s a five-minute call that can change the real cost of owning that lot.
How I Can Help
I’m Robbie English, Broker and REALTOR® with Uncommon Highland Lakes Realty, and I spend a good part of most weeks walking buyers through exactly these questions on Marble Falls and Lake LBJ properties. I’d rather tell you a dock isn’t permitted or a lot sits in a floodplain before you write the offer than have you find out at closing. If you’re weighing a lake lot, reach out or call 830-953-5571 and let’s look at the specific property together.
