CDB Primer
What Is an Ameren CDB?
An Ameren-Certified Dock Builder (CDB) is a contractor on Ameren Missouri's official roster of approved boat dock builders for Lake of the Ozarks. CDB status is the regulatory gate for new dock construction, dock modifications, slip additions, refoaming, and most roof additions at the Lake. Without a CDB-submitted permit application, Ameren won't issue the permit, which means the work can't legally proceed.
To earn and hold CDB status, a builder demonstrates dock construction capability, carries appropriate liability insurance, accepts Ameren's shoreline rules and inspection process, and stays in active good standing with the permit office. CDB numbers are issued in order of certification. A CDB-7 has been on the roster since the program's early years; a CDB-150 is a newer addition.
The CDB program exists because Ameren operates Lake of the Ozarks under a Federal Energy Regulatory Commission license. Ameren is responsible for shoreline integrity, navigation safety, and environmental compliance across the Lake's 1,150 miles. The CDB program is how Ameren ensures only qualified builders work on dock structures that touch the shoreline.
See Ameren's official program page at ameren.com/missouri. The published CDB roster is updated as builders are added or removed.

Choosing a Builder
How to Choose a CDB Builder
CDB status is a baseline, not a differentiator. Every builder on the roster has cleared Ameren's bar. The right CDB for your specific project depends on six factors.
Cove and corridor experience
A CDB who works the Glaize Arm every week may be a poor fit for a Big Niangua project, simply because they don't know the cove's geography or have a barge route worked out. Ask any candidate CDB how recently they completed a project in your specific cove or town.
Project type fit
Some CDBs specialize in premium new builds. Others focus on refoaming and repair work. Others are best on slip additions and lift installs. Match the CDB's day-to-day work to your project type. A premium builder is usually overqualified and overpriced for a simple refoaming job; a repair-focused CDB may not have the design capacity for a 50x50 build.
Realistic lead times
Peak season (March through August) sees stretched calendars. Off-season (September through February) moves faster. Ask any candidate CDB for a realistic start date and project completion estimate. If the answer feels too good to be true, it probably is. CDBs who promise faster timelines than the corridor norm often deliver late.
Written warranty terms
Insist on a written workmanship warranty in the contract. Verbal warranties don't survive turnover at the builder's company. The warranty should specify covered items, exclusions, duration, and the warranty contact. Common Lake of the Ozarks warranties run 1 to 5 years on labor, with manufacturer warranties on materials (often 10 to 25 years).
References and recent work
Ask for 2 to 3 recent project references in your area. A reputable CDB will provide them readily. Drive past the references' docks if possible. The dock you see is the dock you'll get. Pay attention to finish quality, hardware spec, and general workmanship rather than just the dock's overall size.
Permit handling capacity
Confirm that the CDB will handle the Ameren permit application on your behalf and at no separate charge (permit handling is typically included in the build quote). Some smaller CDBs charge a separate permit fee or expect the homeowner to handle parts of the application. Get this clarified in writing before signing.

Frequently Asked Questions
Common questions about Ameren CDB certification and how to use this directory.
What is an Ameren CDB?
An Ameren-Certified Dock Builder (CDB) is a contractor on Ameren Missouri's official roster of approved boat dock builders for Lake of the Ozarks. To earn CDB status, a builder demonstrates structural construction capability, holds appropriate insurance, agrees to Ameren's shoreline rules and inspection process, and stays in active good standing with Ameren's permit office. CDB numbers are issued in order of certification, so a CDB-7 has been on the roster longer than a CDB-150.
Why is the CDB requirement important?
Ameren Missouri operates Lake of the Ozarks under a Federal Energy Regulatory Commission license. Ameren requires that any new dock, dock modification, slip addition, or refoaming permit application be submitted by a CDB. Hiring a non-CDB for permit-required work means the permit can't be filed, which means the work can't legally happen. Ameren can order removal of unpermitted dock work at the property owner's expense.
Can a non-CDB contractor work on my dock at all?
For pure repair work that doesn't touch the dock's structure or flotation (decking replacement, hardware swap, cable replacement), a non-CDB can technically do the work. But most owners hire a CDB anyway because (1) CDBs carry liability insurance specific to lake work, (2) any future modification or refoaming will need a CDB-submitted permit, and (3) CDBs know the corridor's typical failure modes and warranty conventions.
How often is the Ameren CDB list updated?
Ameren Missouri maintains and publishes the official CDB roster on its shoreline management page. The list is updated as builders are added (newly certified) or removed (lapsed certification, business closure, or program violation). We refresh the directory below from Ameren's published roster on a quarterly basis.
How do I verify a builder's CDB status?
Three options. First, check Ameren's official shoreline management page, which publishes the current CDB list. Second, ask the builder directly for their CDB number and verify it against Ameren's roster. Third, ask Ameren's permit office directly, since they can confirm active CDB status by phone or email. The Ameren-certified builders we connect you with all carry current CDB status that you can verify by any of these methods.
What if my builder loses their CDB certification mid-project?
Rare, but it happens. If a CDB loses certification while your project is in progress, ongoing permit applications would need a different CDB to submit. Work already completed under the original CDB's permit is grandfathered. The builders we route projects to all have current good-standing CDB status at the time of routing, but for very long projects (premium 50x50 builds running 9+ months), confirm CDB status quarterly with the builder.
