What Franklin, MI Sellers Need to Know About Wells, Septic, and Grinder Pumps Before Listing

Here is the claim most Franklin sellers don't hold until it costs them time at the closing table: the question on Michigan's Seller Disclosure Statement about your septic system is not a formality you can guess your way through. In a village where water and wastewater infrastructure changes street by street, sometimes lot by lot, that single line is where more Franklin closings slow down than any other section of the form. The reason isn't that septic systems are rare here. It's that in Franklin, more than in most nearby communities, you may not actually know which system serves your address until you check.

Franklin doesn't run on one utility system. It runs on three, layered across a village of roughly 3,000 people and long private lots that predate the subdivisions around it. Some homes draw water from private wells and treat wastewater through a septic tank and drain field. Others connect to a Village-operated gravity sewer. A third group sits on a pressure sewer system, meaning wastewater from the home is pushed to the main line by a grinder pump rather than flowing there by gravity. Which one applies to your house is not something a listing photo, a property tax record, or a neighbor's description will reliably tell you. It has to be verified by address.

The Village's Own Rule, Not Just the County's

Most guidance about Michigan septic law starts and stops at the state level: there is no statewide septic code, and each of Michigan's counties writes its own. That's true, but it undersells what's happening in Franklin specifically. The Village of Franklin has its own ordinance layered on top of Oakland County's rules. Homeowners on septic systems are required to pump and inspect their tanks once every three years, and proof of that pumping has to accompany a $25 Septic Operating Permit filed with the Village. This isn't a one-time inspection triggered by a sale. It's a standing obligation that's been running in the background of your ownership, whether or not you've been keeping track of it.

For homes on the Village's pressure sewer system, a different set of rules applies. Franklin's own municipal code specifies that grinder pump stations on the pressure sewer system have to meet both Village and Oakland County standards. The Village's Water Resource Commission oversees that system and handles the quarterly sewer billing, and if your grinder pump has ever acted up, that's the office fielding the call, not a plumber you found online.

Here's how the three systems break down for a seller trying to figure out what applies to their address:

If you've owned your home for years and never had to think about which of these three columns applies to you, that's the point. Most sellers haven't had a reason to ask until they're staring at a disclosure form with a deadline attached.

Oakland County's Point-of-Sale Rule Changes the Timeline

Michigan has no single statewide law requiring a septic inspection before a home sells. Instead, individual counties decide, and the rules differ sharply from one to the next. Wayne and Macomb counties, both a short drive from Franklin, have no mandatory septic inspection at the point of sale. Oakland County does. When a septic property changes hands here, a point-of-sale evaluation is part of the process, which means the three-year pumping cycle a Franklin homeowner might have let slide can suddenly become the thing standing between an accepted offer and a scheduled closing.

This matters for timing more than most sellers expect. If your last documented pumping was four years ago, or if you never filed the county's paperwork after your most recent one, that gap doesn't surface on the listing photos. It surfaces during due diligence, often after a buyer already has a mortgage commitment on the calendar. Lenders backing FHA and VA loans in particular will not close until the septic system is confirmed to be functioning, which means a seller who hasn't verified their pumping history before listing is negotiating from a weaker position than one who has.

There's also a legislative thread worth watching without overstating it. Senate Bill 771, which would establish statewide septic evaluation requirements tied to system age rather than to a sale, advanced out of Senate committee in June 2026 but has not passed and is not law. It wouldn't replace Oakland County's existing point-of-sale rule if enacted. For now, the operative rule for Franklin sellers is the one already on the books at the county and Village level, not a future one still sitting in Lansing.

Why Guessing on the Disclosure Form Is the Real Risk

Michigan's Seller Disclosure Statement asks directly whether the property has a well, a septic system, or connects to municipal water and sewer, and for septic systems specifically, it asks for the approximate age, the last pumping date, and whether the system has ever failed. The instructions on the form are unambiguous: answer based on what you actually know, mark items unknown if you genuinely don't know, and don't guess.

That distinction has teeth. In a Michigan Court of Appeals case, Pilcher v. Benoit, a buyer discovered a faulty septic tank cover after closing and sued, arguing the seller had committed what the law calls silent fraud by failing to disclose a problem they likely knew about. The court found there was a legitimate factual question about what the seller actually knew at the time they filled out the form. The lesson for a Franklin seller isn't that septic systems are dangerous. It's that "I didn't check" is not the same as "I didn't know," and a disclosure form filled out carelessly can follow you well past the closing table.

Franklin's older housing stock raises the stakes here. Custom homes and long-held estate lots mean some septic systems have been in the ground for decades, sometimes under one owner's entire tenure. If the paperwork from an installation or a past repair was never filed with the Village or the county, or if it was filed under a different owner's name, tracking it down before you list is far easier than reconstructing it under contract pressure.

What to Verify Before You List

A short sequence, done early, solves most of this:

1. Contact the Village of Franklin's offices to confirm whether your address is on well and septic, gravity sewer, or the pressure sewer and grinder pump system.
2. If you're on septic, request your pumping history and current Septic Operating Permit status, and schedule a pump and inspection now if it's been close to three years.
3. If you're on the pressure sewer system, check with the Water Resource Commission for any open service history on your grinder pump station.
4. Confirm with the Oakland County Health Division whether a point-of-sale evaluation will apply to your specific transaction.
5. Fill out the Seller Disclosure Statement's water and waste section only after you have documentation in hand, not from memory.

Why This Matters More in a Market This Thin

Franklin's home values reflect a market where broad trend lines don't tell you much. As of August 2026, the average home value across the village sits above $850,000, up modestly over the past year, while the median list price that same month was in the high $700,000s. Those numbers move around more than they would in a higher-volume market simply because so few homes trade hands here in any given month. When a market closes a handful of sales a year rather than dozens, a single delayed closing over a septic technicality is a bigger story locally than a percentage shift in a headline stat. In a market this thin, the paperwork you have ready before you list matters more than the number you saw on a home value estimate.

Frequently Asked Questions

How do I find out whether my Franklin home is on well and septic or Village sewer? Contact the Village of Franklin directly. Water and sewer infrastructure varies by street, and the Village and its Water Resource Commission can confirm which system serves your specific address.

Does a grinder pump on the Village's pressure sewer system count as public sewer for disclosure purposes? Yes. A home connected to the Village's pressure sewer system, even through a grinder pump, is on municipal sewer service rather than a private septic system, which changes what you need to disclose on the Seller Disclosure Statement.

If my septic tank was pumped two years ago, do I still need to worry about timing? Not urgently, but you should have the Village's Septic Operating Permit on file and documentation ready before you list. Buyers and their lenders will look for proof, not just your recollection of the date.

Selling a home in a village where the utility system changes from one lot to the next takes more than a sign in the yard. It takes an agent who checks the specific mechanics of your address before a buyer's inspector does.
