Dominion Energy is your first stop. Because Dominion owns the shoreline easement around the entire lake, any dock or boathouse you want to build requires their approval before anything else. Their agreement ties dock size directly to how many linear feet of shoreline your property has. Under 54 feet of shoreline? You won’t qualify for a dock or boathouse at all. Over 300 linear feet? You can build up to 3,000 square feet of structure — the maximum allowed for residential use.
Then come the other layers. After Dominion, you’ll work through your county (Louisa, Spotsylvania, or Orange each have their own permitting offices), and potentially the Virginia Marine Resources Commission if your project affects state-owned bottomland. The Army Corps of Engineers may also be involved depending on scope. If your property is in an HOA, many require association approval before you even submit to the county.
Boathouses have their own rules. Flat-roof boathouses max out at 20 feet above normal lake level (250 feet above sea level). Pitched-roof structures can go to 28 feet. Some HOAs restrict or prohibit boathouses entirely — so confirm before you design.
The bottom line
Start the dock conversation early. Permitting can run weeks for a simple replacement, and months for something more complex. Knowing your lot’s shoreline footage and county before you buy is part of doing this right.
People Also Ask
Do I need a permit to replace an existing dock on Lake Anna?
Yes. Even like-for-like replacements typically require Dominion approval and a county permit. Existing licenses don’t always transfer automatically at sale — ask for written documentation.
Can any lot on Lake Anna have a dock?
Not automatically. Lots with less than 54 linear feet of shoreline don’t qualify under Dominion’s guidelines. Lot width and configuration matter significantly.
What's the difference between a dock and a boathouse at Lake Anna?
Both require Dominion approval, but boathouses face stricter review. Enclosed or multi-level structures are more tightly regulated and may be prohibited by your HOA or county, even if Dominion approves them.
