In West Michigan, a lot of expensive real estate problems start with something that looks harmless: a skid steer, a pile of fill, and a “quick regrade” to fix drainage.
The permit that gets missed more than it should is Michigan’s Soil Erosion and Sedimentation Control (SESC) permit under Part 91 (often just called “a soil erosion permit”). Missing it can lead to stop-work orders, fines, forced stabilization work, and a last-minute scramble when a buyer asks, “Were permits pulled for this grading?”
This is not just a new-construction issue. I see it come up with driveway work, barn pads, trails on acreage, shoreline prep, downspout and sump discharge projects, and “we’re just fixing the yard” drainage corrections.
Here’s the closing-safe way to think about Part 91 in 2026: if you disturb enough soil, or you are near water, assume you need to check in with the local enforcing agency before you start.
What a “soil erosion permit” is in Michigan (in plain English)
Part 91 is Michigan’s statewide framework for controlling sediment leaving a job site and ending up in a storm drain, ditch, creek, lake, or a neighbor’s yard. The state sets the rules, but permits are typically issued and enforced locally by a county enforcing agency (CEA) or a municipal enforcing agency (MEA) that has adopted a local ordinance.
That local angle matters for real estate because requirements and processes can vary by jurisdiction, and some municipalities and counties are more restrictive than the statewide “baseline.”
The two permit triggers that catch homeowners and sellers
1) Disturbing one acre or more
A permit is generally required when an earth change disturbs one acre (43,560 square feet) or more. On an acreage property, that threshold can be reached faster than most owners expect once you include grading, spoil piles, access paths, staging areas, and multiple work zones.
2) Working within 500 feet of a lake or stream (regardless of size)
Even if your project is well under an acre, proximity to water can trigger permitting. EGLE’s guidance is that permits are typically required for projects within 500 feet of a lake or stream, regardless of the total earth disturbance size, and they recommend contacting the local agency even when you think you are outside the trigger.
Practical takeaway: If you are on waterfront (including smaller inland lakes), near a creek, or adjacent to a drain or open channel, treat Part 91 as part of your due diligence, not as an afterthought.
Who issues SESC permits in West Michigan?
Part 91 is administered through a mix of county and municipal enforcing agencies. The right starting point is to identify where the property sits (city, township, village) and then confirm the enforcing agency for that jurisdiction.
Kent County (Greater Grand Rapids area)
- Kent County Road Commission is listed by EGLE as the county enforcing agency (CEA) for Kent County.
- Several Kent County municipalities are listed as municipal enforcing agencies (MEAs), including the City of Grand Rapids, Kentwood, Rockford, and Walker (among others).
Grand Rapids also publishes internal procedures referencing the same typical triggers (1 acre or within 500 feet of the water’s edge of a lake or stream). This is one reason city deals can move from “simple landscaping” to “you need a plan on file” quickly.
Ottawa County (Holland, Jenison, Hudsonville, Grand Haven area)
Ottawa County’s Water Resources Commissioner describes their office as responsible for enforcement of Part 91 and the county’s soil erosion ordinance, including permits and penalties.
Allegan County (including parts of the lakeshore and inland acreage markets)
EGLE lists the Allegan County Health Department as the county enforcing agency. The county’s Environmental Health field services page also flags soil erosion permitting and notes that a site visit may be required to determine whether a permit is needed.
Important: Some local ordinances can be more specific than the statewide baseline. Always confirm the enforcing agency and trigger details for the jurisdiction before you schedule equipment.
Projects that commonly trigger Part 91 in real transactions
These are the categories I’d mentally flag any time you are preparing to list, writing an offer, or planning improvements:
- Drainage correction grading (swales, re-sloping, building up low areas, ditch work)
- Driveways and private road work (especially where a ditch, drain, or culvert is involved)
- Pole barns, arenas, and outbuildings on acreage (pads, access paths, clearing)
- New construction and additions (obvious, but often underestimated on “small” builds)
- Pools and large patios (excavation plus spoil handling plus runoff management)
- Trail building and site clearing near water features
- Any earth change near lakes and streams, even if it looks minor
If you are thinking, “That’s basically every nice improvement people make,” you are not wrong. The permit question is not meant to stop projects. It’s meant to keep sediment out of water and off adjacent property. But it also means paperwork and inspections can become part of your real estate timeline.
Why Part 91 becomes a closing problem (even when the work looks good)
Most buyers do not show up at a showing asking about soil erosion permits. The issue usually surfaces later, in one of three ways:
- A neighbor complains (sediment in the street, ditching that changes runoff, muddy water leaving the site).
- A municipal inspection is triggered (often through unrelated building permit activity).
- A buyer’s due diligence catches it (photos show silt fence, visible exposed soil, or the seller mentions “we regraded”).
Once the question is asked, you are usually no longer deciding “Should we permit?” You are deciding how to keep the transaction on track while a permit is applied for, transferred, or closed out.
EGLE specifically links to permit transfer forms and transfer obligations as part of its soil erosion guidance, which is a reminder that permitting can follow the project, not the owner’s intentions.
A closing-safe Part 91 checklist for sellers (do this before you list)
If you are preparing to sell a property where any meaningful earthwork happened recently, use this as your pre-listing playbook.
- Inventory the earthwork. Regrading, fill brought in, ditching, shoreline prep, trails, driveway rebuilds, pads for outbuildings.
- Map the water question. Is there a lake, stream, open channel, or drain anywhere nearby? If yes, don’t guess. Confirm distances and jurisdiction.
- Confirm the enforcing agency. In Kent County, this can mean determining whether the city is the MEA or whether the county CEA applies. In Ottawa and Allegan, start with the county offices noted above, then confirm any local overlays.
- Pull documentation now. If you have a permit, get copies of the approved plan, any inspection sign-offs, and close-out documentation.
- If you do not have a permit, don’t wait for the buyer to find it. Talk to the enforcing agency about whether a permit is required retroactively and what stabilization is needed.
- Stabilize exposed soil. Seed, sod, mulch, and erosion controls are not cosmetic at this point. They are risk management.
- Keep it simple for the buyer. The goal is to hand over a clean file: permit issued (if required), inspections passed, final stabilization completed, permit closed or transferable.
This is one of those areas where being proactive protects your net. Surprises on permits tend to show up as rushed contractor work, price concessions, or delayed possession terms.
A due diligence checklist for buyers (especially near water or on acreage)
If you are buying and you see evidence of recent grading or site work, use this list during your inspection window.
- Ask directly: “What grading, drainage work, or earthmoving has been done in the last 2 to 3 years?”
- Request permits and sign-offs for earth change activities when triggers may apply.
- Look for visual clues: fresh topsoil with no vegetation, straw blankets, silt fence remnants, newly cut ditches, sediment at the curb line, or exposed slopes.
- Understand the water feature risk. A “seasonal” creek or an open drain can matter as much as a named river when it comes to runoff and enforcement.
- Plan for timing. If a permit needs to be applied for or closed out, build that into the transaction strategy rather than hoping it resolves itself.
If your due diligence also includes wetlands, floodplains, shoreline work, or private road/ditch conditions, this is a natural companion check. Those issues tend to cluster on the same types of properties.
Does “normal landscaping” require a permit?
It depends on the scope and location. Some county rules summarize the concept this way: Part 91 applies to certain land use activities that disturb one acre or more, or are within 500 feet of a lake or stream, with an exception commonly described as “normal maintenance on landscaping activities.”
But “normal maintenance” is not a magic phrase that covers regrading, importing fill, changing drainage patterns, or clearing a large area. If you are changing how water moves, or you are near water features, it’s worth confirming with the enforcing agency before you assume you are exempt.
What happens if the enforcing agency gets involved mid-project?
At that point, your objective is to get back to a controlled process: permit coverage (if required), a plan on file, and stabilization measures installed. Michigan law gives enforcing agencies enforcement tools when conditions may contribute to soil erosion or sedimentation and measures are not in place.
Grand Rapids’ own internal SESC procedures also describe enforcement-style outcomes in contractor scenarios, including stopping work and civil infractions when measures are not implemented per plan.
I am not sharing this to be dramatic. I am sharing it because the best time to deal with Part 91 is before the first bucket of dirt is moved, and the second-best time is before you go active on the market.
Transaction strategy when a Part 91 issue shows up
When soil erosion permitting becomes a live issue during a transaction, the solution usually falls into one of these buckets:
- Seller cures before closing: obtain the permit (if required), install controls, complete stabilization, and provide documentation.
- Scope-limited cure: stabilize and bring the site into compliance now, with a plan for final close-out after closing.
- Contract structuring: adjust timelines, responsibilities, or credits so the buyer is not inheriting unknown compliance risk.
The right approach depends on the season, the lender’s requirements, the buyer’s plans, and the risk tolerance on both sides. The wrong approach is pretending it is “not a big deal” and hoping nobody asks the question that they usually ask during inspection due diligence anyway.
How I help clients stay ahead of this
If you are planning to list a property with recent grading, shoreline prep, driveway rebuild work, or acreage improvements, I can help you run a pre-listing permit reality check so you know what a sophisticated buyer (and their inspector) is likely to ask for.
If you are buying, I can help you identify when to pull the thread on permitting early, so you do not burn your inspection window discovering that the timeline is longer than expected.
