Boat dock pricing at Lake of the Ozarks varies more than most newcomers expect. A 1-well aluminum dock can run $22,000. A premium 50x50 concrete build with a sundeck and dual hydraulic lifts can run $129,000 or more. The Lake's combination of Ameren regulation, cove-specific access constraints, and a wide range of build profiles creates a 6x spread between the cheapest and most expensive new docks on the water.
This guide breaks down 2026 pricing by project type: new construction (broken out by material and configuration), modifications (slip additions, refoaming, extensions), repair work, boat lifts, sundeck and roof additions, and Ameren permit fees. We close with the cove-by-cove variance you should expect when comparing quotes.

| Project | Typical 2026 range |
|---|---|
| Dock repair (hardware, decking, cables) | $500 to $15,000 |
| Refoaming (replace foam billets) | $6,000 to $18,000 |
| Boat lift install | $1,800 to $35,000 |
| Slip addition (single) | $8,000 to $25,000 |
| Sundeck addition | $6,000 to $35,000 |
| Roof addition (single slip) | $8,000 to $18,000 |
| 1-well new dock (aluminum or concrete) | $22,000 to $48,000 |
| 2-well concrete dock | $36,500 to $89,500 |
| Premium 50x50 concrete | $98,000 to $129,000 |
What drives dock pricing at the Lake
Four factors explain almost all the variance you'll see between quotes for what looks like the same dock.
- Cove access and water depth. Steep hillside lots (common on the Niangua) require barge-side material delivery and add 10 to 20 percent to labor. Shallow coves (parts of the upper Gravois) constrain lift sizing and limit dock width.
- Material choice. Concrete framing typically costs 25 to 50 percent more than aluminum for the same configuration. The premium buys 30 to 40-year service life vs aluminum's 20 to 30, lower annual maintenance, and stronger resale.
- Configuration and add-ons. A 2-well dock with a sundeck, roof, and hydraulic lift can cost 2.5x a bare 2-well. Add-ons stack quickly.
- Builder scheduling. Peak season (May through September) commands premium pricing because every Ameren-certified builder is fully booked. Off-season quotes routinely come in 5 to 15 percent lower.
New boat dock construction costs (2026)
Most new builds at Lake of the Ozarks are floating concrete or aluminum docks. Pier-and-beam stationary docks are rare on the Lake and reserved for specific shallow-water exceptions.
1-well builds: $22,000 to $48,000
The entry tier. Single-slip dock for a runabout, fishing boat, or small pontoon. Aluminum framing dominates this tier ($22,000 to $32,000), with concrete framing pushing the high end ($28,000 to $42,000). Common on the Gravois Arm, Linn Creek, and Eldon markets where practical budgets and smaller coves favor lighter builds.
2-well concrete builds: $36,500 to $89,500
The Lake's most common premium new build. Two-slip concrete dock, typically with a roof over both slips, a sundeck above, and lifts in both wells. The wide range covers the difference between a basic 2-well at $36,500 and a fully built-out 2-well with composite decking and standing-seam roof at $89,500. Common everywhere from Sunrise Beach to Osage Beach.
3-well configurations: $44,000 to $110,000
For active boating families with three watercraft (often a pontoon, a runabout, and a PWC). Less common than 1- or 2-well builds but the standard step up for owners outgrowing 2-well capacity.
Premium 50x50 concrete: $98,000 to $129,000
The Lake's top tier. Full party-deck footprint with multiple slips, sundeck, roof, integrated lifts, and finished build-outs. Concrete framing throughout, standing-seam metal roofing, composite decking, often outdoor kitchen or wet-bar build-outs. Concentrated on the Glaize Arm around Osage Beach and on parts of the Niangua Arm near Camdenton.
Modification costs (2026)
Modifications are the most common Ameren-permitted work after new construction. Slip additions lead the volume, followed by refoaming and extensions.
| Modification | Typical 2026 range |
|---|---|
| Refoaming a 2-well dock | $6,000 to $18,000 |
| Single slip addition (open) | $8,000 to $15,000 |
| Single slip addition (covered) | $14,000 to $25,000 |
| Dock extension (10 to 20 ft) | $12,000 to $35,000 |
| Full reconfiguration | $15,000 to $45,000 |
| Major rebuild with modifications | $30,000 to $75,000 |
Slip additions are the most common modification by volume. Property owners typically add a slip when an adult child takes over the property, when a PWC enters the family, or when an extra pontoon joins the existing boat collection. Read the slip additions service page for details on slip types and what each costs.
Repair costs (2026)
Repair work covers everything from hardware swaps to full storm-damage rebuilds.
| Repair type | Typical 2026 range |
|---|---|
| Hardware and small parts | $500 to $2,500 |
| Decking replacement (per section) | $1,500 to $4,500 |
| Cable replacement (full set) | $2,000 to $5,000 |
| Foam billet replacement | $4,000 to $12,000 |
| Major storm or ice damage rebuild | $8,000 to $25,000 |
Most repair work doesn't trigger an Ameren permit. Decking replacement, hardware swaps, and cable replacement typically fall outside the permit zone. Refoaming does require a permit because Ameren classifies it as a modification, not repair.
Boat lift costs (2026)
Lift pricing scales with capacity. Match the lift to your boat's wet weight plus a 20 percent safety margin.
| Lift type | Typical 2026 range |
|---|---|
| PWC lift (under 1,500 lb) | $1,800 to $4,500 |
| Cable lift, 4,000 lb | $4,000 to $8,500 |
| Cable lift, 7,000 lb | $7,000 to $14,000 |
| Hydraulic lift, 10,000 lb | $12,000 to $22,000 |
| Hydraulic lift, 15,000+ lb | $18,000 to $35,000 |
Lift installs don't typically require an Ameren permit since the lift sits inside an existing permitted slip. The exception is when slip modification is needed to accommodate the lift, which is rare.
Sundeck and roof addition costs (2026)
Sundecks and roofs add usable space and protect stored boats from sun and weather. Roofs usually require an Ameren permit; pure sundeck additions sometimes don't.
| Addition type | Typical 2026 range |
|---|---|
| Open sundeck (basic) | $6,000 to $14,000 |
| Open sundeck with composite | $10,000 to $22,000 |
| Roof addition (single slip) | $8,000 to $18,000 |
| Roof addition (2-well) | $12,000 to $28,000 |
| Full boat house enclosure | $20,000 to $50,000 |
| Premium sundeck with kitchen build-out | $25,000 to $75,000 |
Ameren permit fees
Ameren permit fees are a separate line item from build cost. For 2026, a standard new construction or modification permit runs $400 to $1,200 depending on dock size and complexity. Refoaming permits sit at the lower end. Premium 50x50 builds and unusual configurations sit at the upper end.
Some CDBs include the permit fee in their build quote. Others itemize it separately. Either approach is fine, but confirm which during the quote conversation so the total cost matches expectations. Read the dock permit guide for the full process walkthrough.
Hidden costs to watch for
- Site access surcharges. Hillside lots, narrow shoreline approaches, or lots without barge-side access can add 10 to 20 percent to labor cost.
- Underwater obstacles. Some Niangua and Gravois coves have submerged stumps or rock that need removal before a dock can be placed. $1,500 to $8,000 in additional cost depending on what's down there.
- Design changes during construction. Mid-build design changes often trigger Ameren re-review and material change orders. Get the design right before the permit application is submitted.
- Materials inflation. A quote pulled in February can shift by 8 to 15 percent by August. The further out your build date, the more variance you should plan for.
- Custom design fees. Premium 50x50 builds and custom Big Niangua configurations often carry separate design fees of $2,000 to $8,000 on top of construction cost.
Cove-by-cove variance (rules of thumb)
The Lake's four arms produce different cost profiles. These are rules of thumb, not guarantees. Your specific cove will produce its own quote.
| Cove | Variance vs Lake baseline | Why |
|---|---|---|
| Main Channel | 1.00x (baseline) | Standard access, premium market expectations |
| Glaize Arm | 1.00x | High traffic, premium builds dominate |
| Gravois Arm | 0.95x | Aluminum dominates, easier access |
| Niangua Arm | 1.05x | Steep hillside lots, premium aesthetics |
| Big Niangua Arm | 1.10x | Custom builds, longer drive times for CDBs |
