Need a Boat Lift Permit in MN, WI or MI? State Rules

Usually not from the state, if the lift is private, sits on an inland lake and is the ordinary removable kind. All three states exempt that lift, but each attaches a different condition, and the conditions do not line up. Minnesota looks at how the lift is built. Wisconsin looks at where it sits and how many boats you moor. Michigan looks at whether the lift comes out of the water every fall. The same lift can be exempt on one side of a state line and need a permit on the other.

Two answers circulate among lake owners. One is "lifts never need a permit up here". The other is "anything on the lake bed needs a DNR permit". The first is closer for a free-standing lift that comes out each fall. It persists because most lake lifts are that kind, and it fails for the cases people actually ask about: a lift left in over winter in Michigan, a hard-roof canopy in Minnesota, a third boat lift on a narrow Wisconsin lot, and anything on Great Lakes frontage. Below, each state's rule text is set out side by side. This is general information, not legal advice.

The three states side by side

The table covers the state layer only: the DNR in Minnesota and Wisconsin, and EGLE (the Department of Environment, Great Lakes, and Energy) in Michigan. Counties, townships, lake associations and the Corps of Engineers sit on top of it, as described in boat lift permits.

Minnesota: the lift has to be built to come out

Minnesota's rule on structures in public waters says no permit is required "to construct, reconstruct, or install a dock, floating or temporary structure, watercraft lift, or mooring facility" if seven conditions hold. For a lift, the ones that matter: no hazard to navigation or safety, free flow of water beneath it, no marina use, and "consistent with or allowed under local land use controls". The 8 ft width limit applies to "the structure, other than a watercraft lift or watercraft canopy", so lifts and canopies escape it.

The word that carries the weight is the definition. Minn. R. 6115.0170 defines a watercraft lift as a device "without walls" that lifts watercraft above the water and "is designed and constructed so that all components may be removed from the lake or stream bed on a seasonal basis by skidding intact or by disassembly with hand tools." A lift "may be designed to include a fabric covered roof."

Removable by design, not by habit. The definition is about how the lift is built. A free-standing lift on adjustable legs fits it whether or not you pull it every fall. A lift on driven pilings that cannot be skidded out or taken apart with hand tools does not fit it, so the no-permit line written for watercraft lifts does not reach it. Take that design to the DNR area hydrologist before you buy.
Fabric roof only. A watercraft canopy is defined as having "a fabric covered roof and without walls or a floor." Captain Ken Soring, a DNR enforcement supervisor, told the Brainerd Dispatch that "boat lifts with metal or other hard-surface roofing do not meet current Minnesota statutes." Separately, the rule prohibits any structure "designed or intended to include walls, a roof, or sewage facilities", and a structure with walls, a roof and a boat well is a "boat storage structure". Side curtains are walls.
Local rules come in through the exemption. Because the exemption defers to local land use controls, breaking a county shoreland ordinance also loses the state exemption.

Senate File 4497, introduced in March 2026, would have the DNR change "fabric covered roof" to "fabric- or metal-covered roof". Its last recorded action is March 17, 2026, and it has not become law.

The sheriff's permit almost nobody knows about

Minn. R. 6110.1800 says no person shall leave "any temporary structure not extending from shore" in state waters between sunset and sunrise "without first obtaining a permit in writing therefor from the sheriff of the county." A watercraft lift is a temporary structure under the definitions in 6115.0170. So a lift standing on its own in the water, not attached to a dock or shore, needs one, with the permit number painted on it and a light or reflective material that keeps 80 percent of its dry reflectivity when submerged. Aitkin County charges $2.00 per year, sold in 5-year increments. A lift beside your dock avoids this entirely.

Wisconsin: exempt in place, but the boat on it is a slip

Wis. Stat. 30.12(1g)(e) exempts "a boat shelter, boat hoist, or boat lift that is placed on a seasonal basis adjacent to the riparian owner's pier or wharf or to the shoreline on the riparian owner's property." Like every exemption in 30.12(1g), it applies only outside an area of special natural resource interest and only where the lift does not interfere with neighbors' riparian rights. The DNR's 2026 Pier Planner then says plainly: "Boat lifts and hoists can remain in place year round." That year-round sentence is the reverse of Michigan's rule.

The limit that catches Wisconsin owners is the slip count. The Pier Planner counts "all watercraft docked at a pier or wharf including boats in a boat lift or hoist" as slips. An exempt pier may have no more than 2 slips for the first 50 ft of shoreline and one more for each additional 50 ft (30.12(1g)(f)). Separately, 30.12(1h) lets you secure up to 2 personal watercraft to the pier for the first 50 ft and one more per additional 50 ft without losing the exemption. The pier itself may be up to 6 ft wide and may run out to 3 ft of water at summer low levels, "or to the point where there is adequate depth for mooring a boat or using a boat hoist or boat lift," whichever is farther. For a deep-draft boat, check water depth requirements.

Canopies: Wisconsin calls them seasonal boat shelters

A roof over a lift turns it into a boat shelter. The DNR's Seasonal Boat Shelters exemption checklist (dated 9/2026) allows the shelter without a permit if it meets every item, including:

No more than 30 ft long and no more than 14 ft wide outside.
A roof, but no walls, sides or equivalent construction.
Roof pitch between 1 ft and 2.5 ft from peak to eaves.
Used for a single watercraft, connected to land by a conforming pier.
The roof "completely removed from the waterway annually between December 1st and April 1st." The Pier Planner adds canopy and supports.
No more than 2 seasonal shelters (or one permanent and one seasonal) for the first 100 ft of frontage, plus one seasonal shelter per additional 50 ft.

Wisconsin sets no fabric-only rule, but the December 1 date matches what canopy makers ask for anyway (see taking a boat lift canopy off for winter). A permanent boat shelter needs a DNR permit and is not allowed on lakes and flowages under 500 acres, or on rivers other than the stretches of the Mississippi, Wolf and Fox the DNR lists.

Worked example: three boats on a 120 ft Wisconsin lot

An owner with 120 ft of frontage wants two boats on lifts with canopies, a third boat tied at the pier, and two jet skis.

Slips: 2 for the first 50 ft, plus 1 for the next full 50 ft (the last 20 ft earns nothing). That is 3 slips. Two boats on lifts plus one at the pier uses all three.
Personal watercraft secured to the pier: the same 2 plus 1 formula allows 3, so two jet skis tied to the pier are within 30.12(1h).
Shelters: 2 for the first 100 ft; the remaining 20 ft is short of the 50 ft that earns a third. Two canopies fit.
The fail case: a fourth boat on a third lift needs a fourth slip, which needs 150 ft of frontage. On 120 ft it takes the pier out of the exemption.

Unsure whether a layout qualifies? The checklist offers a voluntary exemption determination under NR 300.04(4), decided within 15 days of a complete request.

Michigan: seasonal means it comes out

Part 301 of Michigan's Natural Resources and Environmental Protection Act forbids anyone without a permit to "construct, enlarge, extend, remove, or place a structure on bottomland" of an inland lake or stream (MCL 324.30102). The exemption in 30103(1)(b) covers "a seasonal structure placed on bottomland to facilitate private noncommercial recreational use of the water if it does not unreasonably interfere with the use of the water by others entitled to use the water or interfere with water flow." Section 30101 defines a seasonal structure as "any type of dock, boat hoist, ramp, raft, or other recreational structure that is placed into an inland lake or stream and removed at the end of the boating season."

A hoist that comes out each fall is exempt. One left standing through the winter is not removed at the end of the season, so it is not a seasonal structure, and the general rule requiring a permit applies. Attorney Clifford Bloom puts the same point plainly for docks in his guide for the Michigan Lakes and Streams Association: "Permanent docks or piers (i.e., docks or piers that are left in the water year-round) require a special state permit."

Once a permit is issued, the yearly cycle is free. Section 30103(1)(l) exempts the "annual installation of a seasonal dock or docks, pilings, mooring buoys, or other mooring structures previously authorized by and in accordance with a permit," and the Act's definition of mooring structures includes boat hoists.

If you want to leave the lift in, the permit is one cost to weigh against pulling it each fall. Ice is the other, and winterizing a boat lift covers what a lift left in has to survive.

Great Lakes frontage is a different law

Below the ordinary high-water mark of the Great Lakes, Part 325 (Great Lakes Submerged Lands) applies instead of Part 301, and EGLE's page says permits "are required for construction activities such as filling, dredging, and placement of structures such as docks, boat lifts, or seawalls on all of Michigan's Great Lakes Bottomlands." The Part 325 rules carve out only this: "placing spoil or other material on bottomlands does not include" seasonal, private, noncommercial docks and boat hoists (R 322.1008(3)(a)). That is not a statement that the hoist needs no permit. On Great Lakes frontage, contact EGLE before the lift goes in.

The layers above the state

Federal. Under 33 CFR 322.3(a), Department of the Army permits "are required under section 10 for structures and/or work in or affecting navigable waters of the United States" unless an exception or general permit applies. The Great Lakes are navigable waters, and a state exemption does not answer the federal question; see boat lift permits.

Local. Minnesota writes local land use controls into its exemption, and Wisconsin's checklist ends with "A person is responsible for requesting and obtaining all necessary federal, state, and local permits."

Electrical. None of these exemptions covers wiring. Power to a lift on a dock is work for a licensed electrician under a local electrical permit, with the ground-fault protection described in boat lift electrical. Faulty dock wiring can cause electric shock drowning.

Where this answer stops applying

Commercial, marina and multi-unit properties. Minnesota and Michigan exclude marina and commercial use, and Wisconsin has separate slip rules for properties with 3 or more dwelling units.
Minnesota spawning areas. The rule bars construction in posted fish spawning areas.
Moving a used lift in. Permits aside, Minnesota requires a lift from another lake to be out of the water 21 days first, as set out in moving a boat lift between lakes.
Other states. Florida's rules work differently and depend on whether the lift floats; see Florida boat lift permits. Iowa, just south of Minnesota, has no lift exemption: every dock and hoist on public water needs a DNR permit, free for one dock with up to two hoists, $125 for five years from the third hoist (see Iowa boat lift permits). Indiana, to the south of Michigan, treats a removable lift on a public lake as a temporary structure under a general license: no filing, if the frame is no more than 10 by 20 ft, the poles no more than 3 1/2 in across, the top and sides canvas, and the lift within 150 ft of shore (see Indiana boat lift permits).

Frequently asked questions

Can I leave my boat lift in the lake over winter in Michigan without a permit?

Not under the seasonal exemption. Michigan defines a seasonal structure as one placed in an inland lake and removed at the end of the boating season, and only seasonal structures are exempt under MCL 324.30103(1)(b). A hoist left in year round falls under the general Part 301 permit requirement. Once permitted, its yearly reinstallation needs no new permit under 30103(1)(l).

Is a metal roof boat lift canopy legal in Minnesota?

Not under the current rule. Minn. R. 6115.0170 defines a watercraft canopy as having a fabric covered roof and no walls or floor, and a DNR enforcement supervisor has said hard-surface roofs do not meet current law. Senate File 4497 (2026) would allow metal roofs, but it has not become law.

Does a boat on a lift count as a slip in Wisconsin?

Yes. The DNR's Pier Planner counts all watercraft docked at a pier, including boats in a lift or hoist, toward the slip limit for an exempt pier: 2 slips for the first 50 ft of shoreline and one per additional 50 ft. Up to 2 personal watercraft secured to the pier, plus one per additional 50 ft, are allowed on top of that.
