Dreaming of a dock where the boat is ready to go and the kids can jump right in? If your home sits on an East Tennessee lake like Watts Bar, Fort Loudoun, Tellico or Norris, there’s one step that comes before any construction: a TVA Section 26a permit. Here’s a plain-English guide to what it is, what goes into the application and how to keep your dock project on schedule.
What Is a Section 26a Permit?
Section 26a of the Tennessee Valley Authority Act requires TVA’s approval before anyone builds, operates or maintains a structure that could affect navigation, flood control or public lands along the Tennessee River and its tributaries. TVA’s regulations list boat docks, piers, boathouses, boat ramps, shoreline stabilization, water intakes and similar structures as examples. In short, if you’re building a dock on a TVA reservoir, you need TVA’s written approval first.
You can read TVA’s official overview on its Shoreline Construction Permits page, and the full rules are published as the Section 26a regulations.
Does It Matter Who Owns the Shoreline?
Yes, and it’s one of the first things to figure out. On many TVA lakes, the strip of land along the water is TVA-owned shoreland, and TVA’s rules for residential docks on that land are especially detailed. Other shorelines are privately owned but subject to a TVA flowage easement. TVA’s regulations treat structures on flowage-easement land as obstructions that also need 26a approval. Either way, a permit is required. The type of shoreland affects which specific standards apply, which is why we look at land maps, subdivision plats and the site itself before we design anything.
What the Application Includes
For a residential dock, which TVA considers a “minor facility,” the regulations call for:
- A completed application form with a project description explaining what will be built, removed or modified, and in what order
- A plan or drawing showing the type of structure and its purpose, its principal dimensions and location relative to the shoreline, its elevation above full summer pool, and the reservoir name, river mile and landmarks
- A site photograph showing where the dock will go and the adjacent shoreline
- A location map, such as a TVA land map, subdivision map or USGS topographic map, with the subdivision name and lot number if available
- Other permits or consultations that apply, such as from the U.S. Army Corps of Engineers or state water-quality agencies, which should be applied for at the same time as or before the 26a application
Accurate, dimensioned drawings matter. TVA’s rules say applicants must submit plans that conform to its size standards, and TVA can limit the size it approves if site conditions require it.
How Big Can a Dock Be?
On TVA-owned residential access shoreland, TVA’s regulations generally cap docks, piers, boathouses and other residential water-use facilities at a total footprint of 1,000 square feet. The exception is areas of “pre-existing development,” which generally means subdivisions with TVA-permitted facilities before November 1, 1999, or sites near a facility TVA permitted before that date. Narrow coves, water depth and neighboring docks can also limit what’s possible. This is a big reason to settle the layout with your builder before you fall in love with a design.
How Long Does TVA Review Take?
TVA’s own acknowledgment letters, which we receive when we submit applications for our clients, describe four steps:
- Initial review of the application for completeness
- Site inspection by TVA staff
- Environmental and programmatic review
- Project closure, when the permit is issued
Those letters list a typical processing time of about 120 days, and they note that changes during review cause delays. Some projects take longer. One Spring City dock we built needed interagency review of a proposed dredge before TVA issued the permit. Others move faster. For a recent Kingston dock expansion, TVA received our application in early December 2025 and approved it on January 28, 2026.
Bottom line: if you want your dock ready for summer, start the design conversation in the fall or winter.
After the Permit Is Issued
- Don’t start early. Construction shouldn’t begin until every required permit is in hand, including TVA, county and any HOA or local agency approvals.
- Mind the clock. Under TVA’s regulations, a 26a permit expires if construction doesn’t begin within 18 months of issuance.
- Build what was approved. TVA’s permit letters make clear that deviations from the approved plans require additional review, generally a new application.
- Display the tag. TVA provides a permit tag that goes on the most lakeward, visible side of the dock.
- Selling later? When waterfront property with a permitted facility changes hands, TVA’s rules require the new owner to notify TVA within 60 days.
Other Approvals You Might Need
A 26a permit isn’t always the only one. Depending on your project and location, you may also need a county building permit, HOA architectural approval or approval from a local agency. Around Tellico Lake, for example, lakeside projects can require a Tellico Reservoir Development Agency permit. TVA also reviews related work as part of the permit, such as electrical service to the dock, jet ski ports, water intakes, shoreline stabilization and tree removal.
How Smoky Mountain Deck Builders Handles Your Permit
At Smoky Mountain Deck Builders, TVA permitting is part of the job, not an extra chore for you. On our dock projects we:
- Visit the site and review the shoreline, water depth and access
- Design your dock and show it to you in a 3D rendering
- Finalize the layout before submitting, since late changes slow TVA review
- Prepare and submit the Section 26a application with accurate drawings
- Coordinate the TVA site inspection and answer TVA’s questions
- Handle county permits and help with HOA or agency approvals
- Build exactly what was approved and install the TVA tag
We’ve guided dock projects through TVA review on Watts Bar Lake near Kingston, Rockwood and Spring City, on Fort Loudoun Lake in Knoxville and Louisville, and in the Maryville and Loudon areas.
Frequently Asked Questions
Do I need a TVA permit to repair my dock?
Routine maintenance generally doesn’t change a dock, but repairs that change its size or structure, or add new features, need TVA review. When in doubt, ask. We can help you figure out whether your project needs an application.
Can I submit the application myself?
Yes, homeowners can apply directly. TVA’s page explains current submission options. Most of our clients prefer that we handle it, since we’re already producing the drawings.
Does the permit guarantee I can build any dock I want?
No. TVA reviews size, placement and environmental impacts and can require changes or limit the size based on site conditions.
