Yes — most waterfront owners at Smith Mountain Lake can have a dock, and the dock is a large part of what makes waterfront here worth owning. But the shoreline itself is managed by Appalachian Power under a federal hydroelectric license, which means a dock is a permitted structure, not an automatic right. Building or modifying one requires AEP’s Occupancy and Use Permit — and if you are buying a home that already has a dock, that permit does not follow the deed on its own. It has to be formally reassigned to you.
Who actually controls the shoreline
It surprises nearly every out-of-state buyer: you can own the land, the house, and the view, and still not control the water’s edge. Smith Mountain Lake is a working hydroelectric project, licensed by the federal government and operated by Appalachian Power, and the project boundary runs along the 800-foot elevation contour — with full pond at 795 feet. Inside that band, AEP manages what gets built, moved, and modified. Your dock lives in their jurisdiction, under their permit.
That is not a reason to walk away from waterfront. It is the reason lake deals here have a step that deals in a subdivision do not — and the reason you want someone at the table who has handled that step a few hundred times.
The permit, and the closing item everyone forgets
New dock, bigger dock, second slip, major repair — construction and modification run through AEP’s Occupancy and Use Permit. And when a property changes hands, the existing dock’s permit must be formally reassigned to the new owner. It is a paperwork step, not a hard one, but it is the kind of paperwork that gets missed when nobody at the closing table has done a lake transaction before. Buy a dock whose permit still names the previous owner and you have inherited a loose end with a federal licensee. Our buying process guide treats dock transfer as its own stage of closing, because on this lake, it is.
The rules that shape what you can build
A few of AEP’s siting rules are worth knowing before you fall in love with a lot. An access structure has to sit at least 30 feet from any nearby structure, stay within six feet in width, and keep 15 feet clear of your extended property lines. Dredging is tightly restricted — nothing within 10 feet of the base elevation, nothing between the 793- and 795-foot contours — so the depth a shoreline has is, for practical purposes, the depth it keeps. And docks are for boats, not bathrooms: sinks, showers, and bulkheads need variances you should not count on.
Beyond those, AEP’s Shoreline Management Plan carries further siting limits — cove position and shoreline classification matter — which is why two similar-looking lots can have very different dock prospects. That difference is often worth six figures, and it is invisible in the listing photos.
Buying with a dock vs. buying to build one
If the dock exists: verify the permit, verify what it actually covers, and make the reassignment part of your closing checklist. If you are buying a waterfront lot to build: confirm what AEP will permit on that shoreline before you buy, not after. Whether a lot is dockable — and what kind of dock it can carry — is the single biggest value question on undeveloped waterfront at this lake. I have watched it double a lot’s value, and I have watched its absence quietly cut one in half.
Straight answers
Do I need a permit to build or change a dock?
Yes. Construction and modifications both run through Appalachian Power’s Occupancy and Use Permit. Do not let a contractor tell you otherwise.
Does the dock permit transfer automatically when I buy?
No. It must be formally reassigned to the new owner when the property changes hands. Make it a line item in your closing, the same as the survey.
Can I dredge my cove deeper?
Count on no. Dredging is prohibited within 10 feet of the base elevation and between the 793- and 795-foot contours. Buy the depth you need; do not plan to dig it.
Who issues the permit?
Appalachian Power, through the Smith Mountain Project’s shoreline management program. For the full picture — boathouses, siting, what the process feels like in practice — start with our dock and boathouse guide.
