Louisiana dock permits: who actually issues yours

Waterfront permitting in Louisiana is not one rule. Here is the authority that controls the permit, what rides along with it, and the official source — before you build anything.

Watch for this in Louisiana

Inside the coastal zone it is a Coastal Use Permit. Outside it, the Office of State Lands water-bottom permit can apply. Parish and levee districts add layers.

The state program covers the coast. Inland lakes go to the lake operator. Lake operators that can be the real gate here: Louisiana Office of State Lands / local-waterbody manager.

Layers that can apply

• Town or county — local zoning, shoreland and building permits.
• Waterbody owner or operator — reservoirs, utility lakes, river authorities and lake associations.
• State — Louisiana Department of Energy and Natural Resources (Coastal Use Permit).
• Federal — Army Corps of Engineers, see below.

Federal layer (applies in every state)

• Rivers and Harbors Act §10 — a structure in, over or under navigable waters of the United States needs Army Corps authorization unless a general or nationwide permit covers it.
• Clean Water Act §404 — placing fill or dredged material in waters of the United States needs Corps authorization (Michigan and New Jersey run this program in certain waters).
• 2026 Nationwide Permits — effective March 15, 2026. Some docks qualify, sometimes with a pre-construction notice. Regional conditions apply.
• Clean Water Act §401 — a state water-quality certification that rides on a federal permit. It is not a dock permit by itself.

Preliminary regulatory path. Ask Dock.AI is an information tool, not a permitting authority. Rules change and every waterbody has its own owner and wrinkles. Confirm your project with the listed authority before you build. You pull your own permit; we show you the path.
