The most common question we get from homeowners planning a new dock or significant dock replacement: do I need a permit for this? The honest answer is: it depends. Michigan has a layered permitting system involving state, federal, and local authorities, and the requirements vary significantly depending on what you're building, where you're building it, and which lake or water body you're on.
This guide explains each layer in plain language so you know what applies to your situation before you call a contractor or submit anything to a government agency.
Layer 1: Michigan EGLE — Part 301 Inland Lakes and Streams
The Michigan Department of Environment, Great Lakes, and Energy (EGLE) regulates activities in or near the water under Part 301 of the Natural Resources and Environmental Protection Act (NREPA). If you're planning to install, replace, or substantially modify a dock on a Michigan inland lake, Part 301 is the state-level authority you need to understand first.
What Requires a Permit Under Part 301?
In general, these activities in an inland lake or stream require a permit from EGLE:
- Placing fill material in a lake or stream bed
- Constructing a seawall, bulkhead, or revetment
- Significant dredging or excavation in or near the water
- Installing a permanent crib dock or anchored dock structure that involves fill or alteration of the lake bed
- Projects that significantly change water flow, navigation, or fish/wildlife habitat
What Usually Does NOT Require a Part 301 Permit?
- Seasonal pipe docks and aluminum frame docks that are removed each fall — these sit on the bottom without disturbing it and are generally considered temporary structures
- Replacing an existing dock in the same footprint with like materials
- Floating docks secured to shore with cables or anchors (in most cases)
- Minor repairs that don't alter the structure's footprint
The key distinction EGLE makes: Temporary structures that are seasonally removed and don't involve fill, dredging, or permanent alteration of the lake bed typically don't need a Part 301 permit. Permanent structures — especially anything involving concrete, anchored pilings, crib construction, or fill — almost always do.
Part 302: Floodplains and Wetlands
If your property includes wetlands adjacent to the water body, EGLE's Part 303 (wetlands) protections may also apply to your project. Disturbing regulated wetlands without a permit carries significant penalties. If you're not sure whether your shoreline area qualifies as regulated wetland, EGLE offers a wetland determination process.
Layer 2: Army Corps of Engineers — Section 10 and Section 404
Federal jurisdiction kicks in on navigable waters of the United States under Section 10 of the Rivers and Harbors Act, and on dredge/fill activities under Section 404 of the Clean Water Act.
For most Michigan homeowners on inland lakes, Army Corps jurisdiction is less commonly triggered than EGLE's — but it does apply in certain cases:
- The Great Lakes (Lake Michigan, Lake Superior, Lake Huron, Lake Erie): Federal navigation jurisdiction applies. Any significant structure in navigable Great Lakes waters needs Army Corps review.
- Lake St. Clair and the Detroit River: Federal navigable waters. The Army Corps Detroit District actively reviews dock permits in these areas. Homeowners on St. Clair Shores, Harrison Township, Grosse Pointe, and other metro Detroit lakefront communities regularly deal with both Army Corps and EGLE permitting.
- Navigable rivers and connecting channels: If your property is on a river or channel that's legally classified as a navigable water, federal rules apply.
- Nationwide Permits: The Army Corps issues Nationwide Permits (NWPs) that authorize common activities — including many residential dock installations — with minimal review, provided the activity meets specific criteria. NWP 36 covers recreational facilities including docks for individual homeowners.
Layer 3: Local Rules — Townships, Cities, and County Ordinances
This is where things get most variable — and where many homeowners get caught off guard. Local jurisdictions have their own dock regulations that can be more restrictive than state and federal rules, even when no state or federal permit is required.
Common local requirements include:
- Dock length limits: Many townships limit dock length to a specific number of feet from shore or to a certain percentage of the channel width.
- Setback requirements: Minimum distance from property lines extended into the water.
- Width restrictions: Limits on how wide a dock can be.
- Material requirements: Some communities specify or prohibit certain materials (e.g., treated wood near the water).
- HOA and lake association rules: If your property is in an HOA or on a lake with an active lake association, their rules may layer on top of all government regulations.
On Lake St. Clair specifically, we've navigated requirements from Macomb County, St. Clair County, and numerous individual municipalities (St. Clair Shores, Harrison Township, New Baltimore, Algonac, Grosse Pointe Park, and others) — each with their own ordinances. What's allowed in one community may not be in the next one over.
Quick Reference: What's Typically Needed by Project Type
| Project Type | EGLE Part 301 | Army Corps | Local Permit |
|---|---|---|---|
| Seasonal pipe dock (new install) | Usually No | Usually No | Check locally |
| Seasonal aluminum dock (new install) | Usually No | Usually No | Check locally |
| Floating dock (anchored, not fill) | Usually No | Usually No | Check locally |
| Crib dock (new construction) | Usually Yes | Maybe | Check locally |
| Permanent piling dock | Often Yes | Maybe | Check locally |
| Dock on Great Lakes shoreline | Usually Yes | Usually Yes | Usually Yes |
| Dock on Lake St. Clair | Usually Yes | Often Yes | Yes — varies by city |
| Dock repair (same footprint) | Usually No | Usually No | Often No |
| Dock replacement (larger/different) | Depends on scope | Depends on scope | Check locally |
| Seawall / bulkhead installation | Yes | Maybe | Usually Yes |
What Happens If You Skip the Permit?
Building without a required permit in Michigan isn't just a technical violation — the consequences are real. EGLE can require you to remove a dock built without a permit, restore the shoreline to its original condition at your expense, and pay civil fines. Enforcement activity has increased in recent years, particularly in high-visibility areas and on lakes where neighboring property owners file complaints.
Beyond the legal risk, an unpermitted structure can create complications when you sell your property. Title companies and buyers increasingly ask about permits for dock structures, and an unpermitted dock can complicate or delay a sale.
How to Find Out What Applies to Your Property
- Contact your local township or city zoning office first. Ask specifically about dock permits and any local ordinances covering waterfront structures. This costs nothing and takes a phone call.
- Contact EGLE's district office for your area. EGLE has district offices across Michigan. Explain what you're planning and ask whether a Part 301 permit is required. They're generally helpful for preliminary questions.
- For Great Lakes and Lake St. Clair projects, contact the Army Corps Detroit District for guidance on whether federal review is needed.
- Work with a contractor who knows your lake. An experienced local dock contractor has dealt with the regulatory requirements for your specific lake before. We know which townships require local permits, which lakes EGLE watches closely, and where Army Corps jurisdiction applies.
Our approach: When we quote a dock project, we ask about your specific lake and location before finalizing scope. For jobs where permitting may be required, we include it in our project planning conversation so there are no surprises. Call us at (231) 227-8885 — we're happy to walk through what likely applies to your property before you commit to anything.
Michigan's permitting system is navigable when you know the layers involved. Most seasonal dock installations on inland lakes fall well outside the permit requirement threshold, but crib docks, permanent structures, and anything on Lake St. Clair or the Great Lakes warrant a closer look before you proceed.
