New Docks & Boathouses on Lake Guntersville
When replacement beats repair
Most of this site is about fixing what you have, because on Lake Guntersville that's usually the right money. New construction earns its place in three situations: the piling map came back mostly red, the structure was never properly permitted and can't be brought right as-is, or the dock you have simply isn't the dock your family uses — wrong slip size, no lift, no room to sit. In those cases a rebuild resets the clock on everything: structure, hardware, and TVA paperwork.
What the rules let you build
- Footprint: docks, slips, piers, and boathouses must fit within a 1,000 sq ft rectangular envelope at the end of the access walkway — 1,800 sq ft where the property qualifies as pre–November 1999 development. The walkway itself doesn't count against the footprint.
- Reach: no more than 150 feet from the shoreline, or one-third the distance to the opposite shore, whichever is less — this matters in Guntersville's narrower sloughs.
- Height: a second story is allowed as an open deck with railing; roofing or enclosing it is not, and non-compliant second stories are a known removal risk at resale.
- Approval first: construction starts after the Section 26a permit is issued, not before. Building ahead of approval risks modification or removal orders.
How a build runs
- Site look and wish list: water depth, bottom, exposure, boat size, and what your permit envelope actually allows on your lot.
- Drawings and the 26a application — TVA's process is online-only as of late 2025; the plain-English version of the whole process lives in our permit guide.
- Construction from the water: pilings driven to refusal, marine-grade framing and decking, lift installed and tuned, everything matching the approved drawings exactly — TVA compares.
Not sure which side of the repair/replace line you're on? Start with a repair assessment and the piling map — the honest answer is sometimes that your dock has another fifteen years in it.
Frequently asked questions
How much does a new dock or boathouse cost on Lake Guntersville?
Broad typical ranges: open docks and slips commonly start in the $15,000–$30,000 territory; roofed boathouses with lifts commonly run $30,000–$80,000+ depending on size, water depth, and finish. Site conditions move these numbers — quotes follow a site visit.
How long does the whole process take?
Plan on the TVA permit review (up to ~100 days for minor facilities, sometimes longer) plus construction time. Starting the paperwork in fall targets a dock for the next boating season.
Can I roof the second story for shade?
No — TVA rules allow second stories as open decks with railing only. Covered or enclosed second stories are non-compliant and can be ordered modified or removed.
We just bought a lot with an old dock. Rebuild or repair?
First step is the permit record: TVA transfers don't happen automatically at closing, and what you're allowed to rebuild depends on what was permitted. The assessment covers both the structure and the paperwork.
