Michigan dock permits: who actually issues yours

Waterfront permitting in Michigan 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 Michigan

A qualifying seasonal private dock or hoist may not need a permit. Permanent structures generally do. Great Lakes projects add submerged-lands rules.

The state agency below is the main permit path. On reservoirs and lakes owned by a utility, the Corps or another operator, check who owns the water first. The owner can be the real permit gate.

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 — Michigan EGLE (Part 301 inland lakes/streams + Great Lakes submerged lands).
• 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.
