Critical dune area due diligence for Michigan self-directed IRA real estate

A dune does not look like a problem until it becomes one. It can be the long grass ridge running across the back of a lakeshore parcel, the soft, shifting sand that swallows a walkway by spring, or the low pocket between two ridges where water settles after a heavy storm. From the road it reads as open, buildable land. Up close it may be a living system that moves, erodes, and supports plants and animals that do not tolerate much disturbance. For a parcel close to Lake Michigan or Lake Huron, the question to settle early is whether it sits inside a regulated dune area, and what that means for where and how the account can build.

For a self-directed IRA, the dune question lands in two places. First, on the property side: a Critical Dune Area can narrow what the account may construct and add a state permit step before the house, the driveway, or the septic field goes in. Second, on the account side: the permit application, the engineering, and the construction costs that follow have to move through the custodian without giving the owner a personal benefit or a personal signature. A lot that looks like a clean slice of shoreline can still carry a dune boundary that changes the whole plan, and that is worth finding out while the offer is still open.

A critical dune area is a designated boundary, not just a sandy spot

Michigan holds the largest collection of freshwater dunes in the world, and its major dune systems sit along the Lake Michigan and Lake Superior shorelines, with West Michigan's Lake Michigan and Lake Huron lakeshore counties falling inside the mapped Critical Dune Areas. In 1989 the state identified roughly 74,000 acres of dunes along 265 miles of coastline that needed protection from development pressure, and those designated boundaries are the Critical Dune Areas, or CDAs. A CDA is not defined by whether the sand looks interesting on a listing photo. It is a mapped area, a mix of coastal barrier dunes, land with dune-like features, and particular plant communities, where developmental, silvicultural, and recreational activities are regulated.

That is why the first task is to place the parcel against the current CDA maps rather than against the listing description. A property can be well inside a CDA and not feel like it, or it can sit just outside the line where the rules are different. The answer for a specific address comes from the official boundary records and the local authority, not from a seller's impression of the view. Get the CDA status for the exact parcel, save the source and the date, and treat a clean result as a screen, not a guarantee that no dune conditions exist on the ground.

Part 353 is the rulebook the parcel may be working under

Within a CDA, the governing authority is Part 353 of the Natural Resources and Environmental Protection Act, the sand dunes protection and management article of NREPA, at Michigan Compiled Laws 324.35301 and following. EGLE's Water Resources Division administers it, and the statute balances protecting and restoring the dunes against economic development, multiple use, and public access. A permit is required for a regulated use in a CDA, so the practical question is not whether the dunes are pretty but whether the work the account wants to do is one of the regulated uses.

EGLE lists typical activities that call for a permit application: building a house or a garage, putting in a road or driveway, installing a septic system, adding retaining walls, and removing sand. The same office notes that some smaller projects can proceed without a permit when they meet specific criteria, and it gives stairways as a common example. An elevated stairway that is no wider than five feet including its entry and exit platforms, has no roof or walls, is built without wheeled or tracked self-propelled equipment, and touches vegetation only within its footprint can fall outside the permit requirement. A stairway that misses any of those points does not. The line between no permit and a permit is a project-specific one, and the responsible move is to confirm it in writing with the permitting office before the account commits to a design.

Know who will actually run the permit for this parcel

• Confirm the parcel's CDA status against the current official maps and note the date and source
• Ask which local unit, if any, administers Part 353 through its zoning ordinance for this address
• List the proposed work: house, garage, driveway, septic, retaining walls, sand removal, stairways, or other items
• Separate the items that clearly need a permit from the ones that may be exempt under specific criteria
• Ask the local health department what a new or replacement septic system will require on this parcel

Part 353 can be administered two ways. Local units of government may choose to run it through their zoning ordinance, while EGLE administers it directly in all CDAs except a small set of communities, which EGLE currently lists as Pere Marquette Township in Mason County and Peaine and St. James Townships on Beaver Island. If the parcel is one of those locally administered areas, the zoning administrator is the first call. For a West Michigan shoreline parcel in most other counties, the permit question goes to EGLE. The distinction matters because it changes who the account talks to, which forms are used, and how long the review can take.

The EGLE process has a shape the budget should respect

EGLE's CDA program describes a workable path. A property owner may request a pre-application meeting, an optional service where local EGLE staff discuss the proposed project before a formal application is written. Applications for both the meeting and the individual permit are submitted through the MiEnviro Portal. Once an application is in, EGLE staff review it and visit the site to assess the proposed impact on the CDA, and the status of the application can be tracked in the portal.

The timing is part of due diligence, not just a footnote. EGLE describes a 30-day administrative completeness period, during which the application is checked for required information and set on hold if anything is missing. Once complete, the agency has 60 days to process the permit application, or 90 days for a project that requires a public hearing. A valid permit can be transferred to a new owner with the current permittee's written permission, and that transfer is requested in the portal. These windows are general, they can move, and they interact with the purchase contingency dates, so the account's team should build the real calendar from the specific parcel and the specific project, not from the averages.

An application is a package, not a single form

EGLE says every CDA permit application must include a completed online form, property owner authorization, the property location, a local health department permit if a new or replacement septic system is proposed, a soil erosion and sedimentation control permit or waiver from the local agency, and a vegetation assurance. The proposed impact has to be identified and quantified, with a site plan and a cross-section submitted. Some projects need more, and EGLE staff will ask for it. Projects that cannot meet the standard review criteria of Part 353 go through a special exception process, and EGLE may require a surety bond to make sure the permit is carried out as approved.

Two practical points from that list deserve their own attention. The septic item means the dune permit and the health department permit are not independent; they move together, and a delay in one can hold up the other. The soil erosion item means the state erosion and sedimentation rules from Part 91 can apply alongside the dune rules on the same earthwork, so the account should not assume a single permit covers every layer of the project. West Michigan adds one more wrinkle: much of the usable ground is close to water, and shoreline work, dock or shore structure decisions, and wetland conditions can pull in additional reviews. The point is to find the full set of approvals early, because the dune permit is rarely the only one on the table.

Price the constraint, not the view

A CDA is not a reason to walk away, but it is a reason to stop pricing the property the way an unrestricted lot is priced. If the building pad shifts to stay clear of the dune boundary, what does that do to the footprint and the foundation plan? If the septic field moves, does the parcel still have usable ground for it? If a driveway or a retaining wall needs a permit, what does the application fee, the engineering, and the construction add? EGLE lists the CDA permit application fee in a range from $150 to $6,000, added on top of all other application fees, so the cost of the process itself is not negligible next to the other line items.

Do not net out a known dune or permitting cost against assumed rent, occupancy, appreciation, or a seller concession that may never arrive. None of those results is guaranteed, and none of them pays for a permit the account may still need. The account also needs enough liquidity to carry the engineering, the permit fees, the bond if one is required, and the construction, while it keeps paying the property taxes and insurance. A lot that prices low against the neighborhood can still be the wrong price once the buildable ground and the permit path are counted honestly.

Keep the dune work inside the IRA's process

Every step in this review has an account-side version. The IRA owns the property, so the CDA permit application, the engineering, the vegetation assurance, and the construction belong to the account, not to the individual. The account, through its custodian, is the applicant and the owner. The owner does not sign the application in a personal name, pay the engineer or the contractor from a personal account, or do the grading and clearing with personal labor. IRS Pub 590 and the prohibited-transaction rules are what keep a personal lakeshore project from becoming a problem for the whole account, and the custodian should confirm how the account names itself on the application, who is authorized to sign, and how each payment leaves the account.

For a rental, decide who monitors the property, keeps the permit and site-plan records, and handles an erosion or wind event, and make sure those procedures are applied consistently. Tenant selection and property management must comply with the Fair Housing Act and applicable Michigan and local protections. Dune capacity, permit limits, or a special exception are property facts, not a reason to treat any applicant or tenant differently on the basis of a protected characteristic. Have Michigan counsel review the rental policies for the specific property.

This article is educational, not legal, tax, financial, environmental, engineering, fair-housing, retirement-plan, or investment advice. No property, CDA determination, permit, or strategy is approved or endorsed by the IRS. Have your own self-directed IRA custodian, CPA, Michigan attorney, qualified environmental or dune professional, licensed land surveyor, septic professional, EGLE, and other qualified advisors review the account, the parcel, the CDA boundary, and any proposed work before taking action.

What Rennie can coordinate

Primary sources for the public-rule portions of this review are EGLE's Sand Dunes and Critical Dune Areas program pages, Part 353 of the Natural Resources and Environmental Protection Act at Michigan Compiled Laws 324.35301 and following, and EGLE's 2026 delineation of critical dunes. Those sources describe the framework in general, including that EGLE administers Part 353 in all CDAs except Pere Marquette Township in Mason County and Peaine and St. James Townships on Beaver Island, and that a CDA permit application fee ranges from $150 to $6,000 on top of other fees. The answer for one parcel and one project comes from the current official maps, the local or state permitting office, and the buyer's own qualified professionals.

Rennie can help identify West Michigan property and organize the real estate side of the review: the CDA status for the exact parcel, the public records, the offer calendar that gives the account's advisors time to finish the permit work, and the coordination with the local or state permitting offices. The dune determination, the permit questions, the tax treatment, and the retirement-account structure stay with the buyer's own custodian, CPA, attorney, and environmental professionals.
