Most buyers who call me have done their homework. They have studied listings, driven around the lake, and already know which direction the chairs face at sunset.
What almost no one has studied is the regulatory layer sitting underneath every Lake Michigan property. That layer controls what you are allowed to build, improve, or even plan. And it applies whether you know about it or not.
The rule that surprises buyers most is the High-Risk Erosion Area (HRA) designation. If you are shopping for Lake Michigan property in Southwest Michigan, understanding this before you write an offer is essential.

Lake Michigan’s High-Risk Erosion Areas Set the Rules for Every Parcel
An HRA is a shoreline designation assigned by Michigan’s Department of Environment, Great Lakes, and Energy (EGLE). It applies when a stretch of Lake Michigan shoreline loses more than one foot of land per year, averaged over fifteen years. Beyond just describing the condition, it also limits what you can do with the land.
When a property sits within an HRA, EGLE establishes two setback thresholds based on measured erosion and projected rates. One is a 30-year setback, and the other is a 60-year setback. Those thresholds determine where any structure can be placed, and they limit what you can add to an existing home.
Here is what catches buyers off guard: if your planned addition falls within that setback zone, EGLE can stop it. Everything on the lakeshore side of the setback line is effectively off-limits for new construction or significant improvement. Knowing this before you fall in love with a listing puts you in a much stronger position than finding out after you have committed.
Movable Foundation Requirements and What They Mean for New Builds
For new builds within an HRA, the restrictions are more stringent. A home cannot be built on a slab foundation within the 30-year setback. It must sit on a movable foundation, a crawl space, block foundation, or poured concrete. That way, the structure can be relocated if the bluff erodes beneath it.
Drew Vinton, a Lake Michigan property specialist on my team, brings deep experience in this specific coastal market. He puts it plainly:
“If you’re within that 30-year setback, the additions, site improvements, anything like that, most of the time, you can’t do anything towards the lake. It has to be inward, away from the lake, if you want to make an improvement to the property. But as far as a new build in an HRA, if you’re within that 30-year setback, it has to be put on what they call a movable foundation. They only allow a garage on a slab. You have to put it on a crawl space, block foundation, or poured concrete so that if the bluff ever erodes, the home can be moved.” – Drew Vinton, Lake Michigan Specialist, Lake Life Realty
Lot Depth Is a Strategic Factor in HRA Zones
Most buyers think about lot size in terms of yard space, privacy, and parking. On a Lake Michigan HRA property, lot depth takes on an entirely different meaning.
If the bluff erodes and the structure needs to be relocated, there has to be somewhere on the parcel to move it. A lot that looks generous on a listing sheet might not carry enough usable depth to absorb a relocation. Before you write an offer, consider this question: if I had to move this home back from the bluff, does this parcel have room for that?
It feels abstract until the bluff starts moving. Then it is the only question that matters.
The Coastal Zone Management Act provides the federal framework that shapes how states like Michigan regulate high-risk coastal zones. EGLE administers Michigan’s program, and the setback boundaries it enforces on Lake Michigan properties are not suggestions.

The 2015 to 2020 Water Rise Changed the Shoreline Math in Southwest Michigan
Between 2015 and 2020, Lake Michigan water levels rose significantly. Beaches disappeared, and bluffs eroded at accelerated rates. Homeowners and HOAs along the Southwest Michigan shoreline were forced to act fast.
The response, in many cases, was the installation of seawalls and revetments: large stone barriers placed at the base of the bluff to slow erosion. At the time, those installations ran $2,000 to $3,000 per linear foot. For a 100-foot frontage property, that is a $200,000 to $300,000 expense that arrived with almost no warning. HOAs with shared bluff frontage levied special assessments across all member properties to cover the work.
Water levels have receded since that peak, and some beaches have returned. But the HRA designations that resulted from that period remain in place. The underlying cyclical risk does not disappear when the water drops. Buyers who understand that going in are the ones who budget for it correctly.
Drew has guided buyers through enough of these situations to know that the regulatory layer is rarely the first thing buyers ask about. His take on what matters most before writing an offer is direct:
“The thing they probably don’t understand is the critical dunes and high-risk erosion question, the environmental issues of being along the lake and the restrictions for any improvements or anything they want to make over time. I think that’d be the biggest question I’d ask.” – Drew Vinton, Lake Michigan Specialist, Lake Life Realty
What to Confirm Before You Write an Offer on Any Lake Michigan Property
Before making an offer on any Lake Michigan property in Southwest Michigan, confirm whether the parcel carries an HRA designation. Review the 30-year and 60-year setback lines relative to the current structure and any planned improvements. If your renovation vision conflicts with what EGLE permits inside the setback, you need to know that before committing.
If you are looking at vacant land, ask whether the building envelope sits inside the HRA and what foundation type EGLE requires. Ask whether the lot carries enough depth to relocate the home if bluff erosion becomes a future issue.
The same due diligence mindset applies to water rights and dock access, too. These are the standard questions every serious Lake Michigan buyer should work through before writing an offer.
Questions Buyers Ask About HRA Designations on Lake Michigan
How do I confirm whether a Lake Michigan property is in an HRA before writing an offer?
Check EGLE’s Shorelands mapping tools, or work with a broker who pulls HRA status as a standard step in the evaluation. MLS listings and real estate portals do not flag these designations. The confirmation needs to happen before you write an offer, not during inspection.
What construction is allowed on a Lake Michigan HRA property inside the 30-year setback?
Within the 30-year setback, EGLE generally prohibits new slab-foundation structures. Garages on a slab are permitted. All other new construction requires a movable foundation: crawl space, block, or poured concrete. Additions and site improvements must be directed away from the lake. Anything toward the lakeside of the setback line is typically off-limits.
Can I renovate or expand an existing home on a Lake Michigan HRA property?
Renovations that stay within the existing footprint are generally possible. Expansions that push toward the lake or into the setback zone are subject to EGLE restrictions. The answer depends on which setback zone your structure sits in and what the proposed improvement involves. A broker with Lake Michigan HRA experience can help you frame the right questions before you hire a contractor.
How does HRA status affect the purchase price of a Lake Michigan property?
HRA designation does not automatically lower a property’s value, but it directly affects future improvement potential. A parcel with a constrained building envelope and limited lot depth for relocation carries more long-term risk than one with room to maneuver. Buyers who understand the designation negotiate with clearer information.
What happens if Lake Michigan water levels rise again after I purchase?
The 2015 to 2020 high-water cycle caused significant bluff erosion and forced emergency shoreline protection work. Stone revetment installation ran $2,000 to $3,000 per linear foot at that time. HOA properties spread those costs through special assessments. Water levels are cyclical, and the erosion risk that led to the existing HRA designations can return. Budgeting for this possibility is part of owning Lake Michigan frontage.
Does a critical dunes designation work the same way as an HRA?
No. Both are EGLE designations that restrict development on Lake Michigan properties, but they address different risks. Critical dune designations protect ecologically sensitive dune systems and restrict grading, vegetation removal, and construction. HRA designations address active erosion rates and govern setbacks and foundation requirements based on land loss data. A single parcel can carry both designations simultaneously.
What should I ask a seller about shoreline protection work on a Lake Michigan property?
Ask whether any seawall, riprap, or revetment has been installed, when it was done, who did the work, and whether EGLE permits were obtained. Ask whether the HOA has levied any special assessments related to shoreline protection in the past ten years. Ask whether any EGLE permit applications have been submitted or denied for the property. Getting those answers upfront puts you in control of the conversation before you inherit the history.
Are Lake Michigan properties with HRA designations harder to insure or finance?
Standard homeowner’s insurance typically excludes damage from shoreline erosion. Insurers categorize it as a land movement loss rather than a weather event. Lake home insurance specialists can sometimes structure coverage that addresses structural risk on bluff properties, but this requires specific underwriting. For financing, lenders may factor bluff condition and lot depth into appraisal review for properties in active erosion zones.
