Benzie Has Required a Septic Inspection to Sell a Home Since 1992. Cross Into Grand Traverse and It Depends on How Close You Are to the Water.
Picture two nearly identical cottages on the same inland lake, a quarter mile apart. One sits in Benzie County, the other in Grand Traverse. The Benzie seller has to pass a septic inspection before the deal can close. The Grand Traverse seller might not, and whether they do comes down to a tape-measure reading from the shoreline.
That’s not a loophole or an oversight. That’s just how septic rules work up north, and it catches second-home buyers off guard almost every season.
Michigan Is the Only State in the Country Without a Statewide Septic Code
Every other state sets baseline standards for how septic systems get inspected. Michigan hands that job to roughly 45 local health departments, each writing and enforcing its own rules. The result is a patchwork where the requirement to prove your septic system works can flip on and off as you drive from one township to the next.
That may finally be changing. Senate Bill 771, sponsored by Sen. Sam Singh of Lansing, went in front of a Senate committee this spring and would end Michigan’s status as the lone holdout. As Singh put it, Michigan is the only state in the entire country that doesn’t have a statewide septic code.
The bill would build a statewide database of where septic systems actually are, require periodic evaluations, and direct the state to write uniform standards within three years. Until that lands, though, the county line is still the line that matters.
The Time-of-Transfer Map, County by County
Here’s the ground truth for the four counties we work in most, and it’s worth committing to memory before you fall in love with a listing.
Benzie County has required a time-of-transfer evaluation since 1992, the longest-running program up here. If you’re buying anything with a well and septic around Frankfort, Beulah, or Crystal Lake, plan on an inspection as part of the sale. You can dig into the area over on our Frankfort guide.
Leelanau County joined the club much more recently. The Benzie-Leelanau District Health Department adopted a unified sanitary code effective January 27, 2023, so the entire county now requires a well-and-septic evaluation before a property transfers. If you’re shopping Lake Leelanau, Suttons Bay, or Cedar, the septic inspection is now standard.
Grand Traverse County is the newest and the trickiest. As of January 2026, a time-of-transfer evaluation is only required for homes within 300 feet of surface water. Buy a place two blocks off the bay and you’re likely exempt; buy the one on the water and you’re not. Commissioners started with the shoreline properties and have signaled they may expand it later as more inspectors get trained.
Antrim County doesn’t have a countywide rule at all. Instead, individual townships opted in, including Milton, Torch Lake, and Elk Rapids Township, plus the Village of Elk Rapids. So a cottage on Torch Lake triggers an inspection, while a similar place a few miles inland in a township that never adopted the ordinance may not. We see this trip people up constantly along the Elk Rapids and Torch Lake corridor.
What a Septic Inspection Actually Checks, and What It Costs
A time-of-transfer evaluation isn’t the wave-a-flashlight walkthrough a lot of buyers picture. The inspector locates and often uncovers the tank, checks the baffles and the drainfield, and pulls a water sample from the well to test for bacteria. Well and septic are usually evaluated together, because up north they’re a matched set.
Budget accordingly. In Grand Traverse County the time-of-transfer inspection runs about $850, which folds in a roughly $65 water test and a $300 health department fee. And remember the tank usually has to be pumped before the inspector shows up, which is an added cost that typically lands on the seller.
There’s also a clock. A Grand Traverse certification is good for 36 months, and Leelanau’s evaluations are valid for three years with the water test only good for six. That means an inspection from a sale two years ago might still count, or might already be stale, so it’s worth checking before anyone pays to redo one.
How to Keep This From Blowing Up Your Deal
The single biggest mistake we see is treating the septic inspection as a formality you handle right before closing. In these markets, a failed drainfield can mean a five-figure replacement, and August is the worst possible time to discover it, when every excavator in the county is booked solid.
Over 25 years up here, Janel has watched these ordinances roll out one county at a time, and the pattern is always the same: the buyers who win are the ones who ask which rules apply before they write the offer, not after. Call the health department for the property’s county, or better, ask your agent to, and confirm whether an inspection is required and whether a valid one already exists.
Then write it into the deal on purpose. Who orders the septic inspection, who pays for the pump-out, who’s on the hook if the system fails, and how long the seller has to cure it are all negotiable, and they play very differently on a lakefront property in Leelanau than on a wooded lot in an Antrim township with no ordinance at all.
The Rules Are About to Get Less Weird, Eventually
If SB 771 becomes law, a lot of this county-by-county guesswork gets replaced by one statewide standard, plus a database that finally tells everyone where these systems even are. That’s genuinely good news for buyers, sellers, and the lakes themselves.
But within three years of a bill that’s still in committee is a long runway, and in the meantime the septic inspection question up north is still answered one county line, sometimes one township line, at a time. If you’re weighing a property and can’t tell which side of that line you’re on, that’s exactly the kind of thing we sort out before it becomes a closing-table surprise.
Thinking about buying or selling a place with a well and septic in Grand Traverse, Leelanau, Benzie, or Antrim County? Reach out and we’ll tell you exactly what the rules are for that address before you’re in too deep.
