Boathouse Rebuilds on Lake Grapevine
A permitted structure taken back to bare pilings and rebuilt to the original footprint — new substructure, decking, roof, lift and lighting, engineered for today's boat weights.

Boathouse rebuilds and shoreline work on Lake Grapevine.
Grapevine is a closed-inventory lake. New boathouse permits are not being issued, so the whole game here is what you can do with a structure that already holds one — and what you can build on your own ground behind it.
The Permit Situation
No new boathouses. The ones that exist are the ones there will be.
The Grapevine Lake Office is explicit about it, and it is the single most important fact about waterfront property on this lake.
Lake Grapevine is a 6,700-acre U.S. Army Corps of Engineers reservoir on Denton Creek, a tributary of the Elm Fork of the Trinity, straddling Tarrant and Denton counties between Grapevine, Southlake, Flower Mound and Trophy Club. The Grapevine Lake Office — 817-865-2600, part of the Fort Worth District's Trinity Regional Project — administers the shoreline, and it states that new boathouse permits will not be issued.
An existing boathouse transfers with a notarized bill of sale and an inspection, after which the new owner is issued a five-year shoreline use permit at a current fee of $35. The permitted use is boat storage. Living quarters are not allowed. And a rebuild is not a free hand: it requires Lake Office approval, and the rebuilt structure must match the original footprint or be smaller than it.
That last clause is what separates a Grapevine project from a project on an open-permit lake. Every design decision — slip width, roof line, deck extension, lift capacity, storage — has to be made inside a fixed outline someone else drew decades ago. Older boathouses cluster in McPherson Slough, and many are now well past the age where the substructure carries what a modern lift and a modern boat weigh.
How It Goes
From bill of sale to finished rebuild.
The sequence matters. Work started before the Lake Office signs off is work that may have to come back out, and a footprint measured wrong is a rebuild that fails inspection.
1
Transfer and inspect
A notarized bill of sale plus inspection is how a permitted boathouse changes hands. The inspection is also your best free structural assessment — read it before you plan anything.
2
The five-year permit
A shoreline use permit runs five years at a current fee of $35 and covers boat storage only. No living quarters. Design accordingly, and keep the permit current through the build.
3
Rebuild to the footprint
Lake Office approval first, then a rebuild that matches the original footprint or comes in smaller. Everything gained has to be gained in engineering and finish, not in square feet.
What We Build Here
Work that fits Grapevine's rules.
Rebuild inside the outline, or build on the private ground behind it. Those are the two honest options at Grapevine.
Seawalls & Retaining Walls
Wall and slope work on private ground above the federal boundary, matched to Grapevine's rock and boulder banks rather than to soft-soil assumptions.
Repairs to Permitted Structures
Decking, walkways, bumpers, hardware and rot repair on an existing permitted structure — keeping it serviceable and inside what the Lake Office has approved.
Marina & Commercial Facilities
Slip systems, access piers and shoreline structures for organizations holding their own agreements on the lake.
Know the Water
Rock, timber, and a ten-foot swing.
Grapevine has an unusual amount of hard bottom for a North Texas reservoir, and that shows up in the cost and method of every pile.
The shoreline carries boulders, and there are submerged boulders offshore — driving conditions that punish a crew equipped for mud. Flooded timber stands in the Twin Coves area, and terrestrial vegetation floods whenever the lake runs above conservation pool.
Conservation pool sits at 535 feet msl, and Texas Parks and Wildlife reports fluctuation of five to ten feet. Ten feet is enough to leave a lift stranded or a walkway underwater if the structure was set for a good day, so pile length, walkway slope and bumper heights get worked out against the range rather than the reading on the gauge.
Questions We Hear
Lake Grapevine FAQ.
Can I get a permit for a new boathouse on Lake Grapevine?
No. The Grapevine Lake Office does not issue new boathouse permits. Buying a property with an existing permitted boathouse is the only way onto the water with a covered slip here.
Can I make my boathouse bigger while I rebuild it?
No — a rebuild has to match the original footprint or be smaller, and it needs Lake Office approval before work starts. What you can improve is everything else: substructure capacity, lift, decking, roof, storage layout and finish.
Can I add a room or sleeping space?
No. The permit covers boat storage, and living quarters are not allowed. Enclosed storage is a different question and worth asking the Lake Office about at the design stage.
Does the boulder shoreline change how you build?
Considerably. Rock changes pile type, embedment and driving method, and it is the difference between a wall that stands and a wall that racks. It gets confirmed on site before a bid, not assumed from a map.
Is Lake Grapevine inside Shoretech's service area?
Yes. Dave travels as far as a project warrants across Texas and western Louisiana. Call 936-662-5100 and describe the structure, the permit status and the shoreline.
