Ameren dock permit: Lake of the Ozarks rules, fees and transfers

On Lake of the Ozarks, MO water, the lake operator is the real permit gate. Here is who issues it, the rules, the fees and the official sources — before you build or buy.

How to get the permit

• Any activity affecting project lands needs an Ameren permit before work starts: docks, breakwaters, seawalls, riprap, dredging, ramps, piers, decks, steps, pumps and geothermal coils. No habitable structures.
• Apply in Ameren's online portal. Apply from the property owner's Ameren account — if a builder applies from the builder's own account, the builder becomes the permit holder.
• Include the fire-district permit or electrical approval (docks and pumps) and to-scale drawings on 8.5 x 11 paper showing distances to extended property lines, neighboring docks and the cove or channel center.
• Only an Ameren Certified Dock Builder or the property owner may build or modify a dock.
• New or modified docks must be finished within 1 year (one 6-month extension). An expired permit is void.

Size and placement rules

• Residential docks: up to 125 ft wide, slips up to 55 ft long, 10 slips or fewer.
• Coves up to 500 ft wide: no more than one-third of the distance to the opposite shore, or 25 ft to the cove center, whichever limits more, and no more than 100 ft.
• Coves over 500 ft: no more than 20% of the way across, up to 350 ft. Main channel: no more than 25%. No dock over 350 ft long, breakwaters included.
• At least 5 ft from the side property line extended. Parallel slips or lifts 15 ft or longer: 1.5 times their length from the line.
• Docks over 3,000 sq ft need plans signed by a Registered Professional Engineer.

Fees

• New dock or modification, any size: $550. Docks 3,000 sq ft and up: $0.06 per sq ft, billed yearly.
• Breakwater $1,000 new / $500 renewal · pier $100 · deck or patio $100 · steps $50 · boat ramp $300 · dredging $500 · extension $50.
• Permit transfer $100 ($200 if filed more than 24 months after the land transfer). Work without a permit: double the fee, up to $2,000.

Buying or selling a lake house

• The new owner files a transfer application with the fee, the deed and an approved electrical inspection (within the last 12 months in listed fire districts).
• One application covers every permitted facility on the property. The permit number stays with the property.

Other layers that can apply

• Town or county — zoning, shoreland and building permits.
• State — see the state page for your lake.
• Federal — Army Corps Section 10 / Section 404 where the work triggers them.
