Manchester has roughly 1,149 housing units and about 60% of them are single-family detached. The year a house went up decides more about what an inspection turns up than almost anything else about it, which is why it is where we start rather than where we finish.
More of it dates from the years before 1940 than from any other decade — 353 homes, roughly 31% of the town.
The median owner-occupied home here is valued at $210,700.
This is not a forecast for any one address. It is where a Manchester home inspector starts in a home of this age — and whatever we actually find, it goes in the report with photographs.
Housing figures: US Census Bureau, American Community Survey 2022 five-year estimates.
When Manchester was built
85% of homes here run on utility gas. Another 18 use bottled or LP gas.
Local knowledge
Manchester publishes something most municipalities do not: a plain-English page telling residents which water problems are the house’s fault and which are the City’s. It is, almost word for word, the distinction a home inspection exists to draw, and it makes this an unusually easy place to ask the right question of the right person.
The first thing to know, though, is a money one. The City states that delinquent water utility bills remain with the property, not the occupant, and that under Michigan Compiled Law it may charge those bills to the property and place a lien against it. A buyer can inherit a seller’s unpaid water bill. Ask for the utility account status in writing before closing, every time.
Second, a naming point that trips people up. Manchester is a city. Its council, clerk and offices are all city ones, and the local construction authority lists the City of Manchester and Manchester Township as separate members. Plenty of people, listings and older documents still say village out of habit, so when you go looking for ordinances or offices, look for the city.
Third, the drainage history. Manchester used to run a combined sewer system, and the City records that in 1990 the storm sewers were fully separated from the wastewater sewers, significantly reducing overflows. That is a genuinely useful thing to know in a town where the largest group of houses predates 1940 — because it tells you the below-ground arrangement at an old house may have been altered mid-life.
The housing itself has two peaks and a hollow between them: about 353 units predate 1940 and about 312 went up in the 1990s, while the entire span from the 1940s through the 1980s accounts for roughly 359 between them. Around 40% of the stock is not a detached house, which is a high share for a town this size.

Before you buy
Water
The City’s common water problems page carries a table headed, in effect, when to call a plumber and when to call the City. We would happily hand that page to a client. It is honest, specific, and it saves people money.
On brown water the City points to hydrant flushing and other disturbances loosening deposits in the mains, and notes that in dead-end lines iron bacteria or iron deposits can accumulate. On cloudy water it names air entering the system, and lists a faulty water softener and the home’s own plumbing alongside hydrant flushing and main breaks as possible causes.
The detail we like most is this one: a rotten egg odor from the hot water only is usually the magnesium rod in the water heater. That is a home-inspection finding, published by a city, and it is correct. If the smell is in both hot and cold, the City suggests flushing the system first.
On low pressure the City is equally straight: it is most often something inside the home’s own plumbing, and only if nothing is found there does a main break become the likely explanation.
All of which lines up with what we do. We run fixtures to see how the system behaves under load rather than testing one tap, we look at the water heater’s age, its temperature and pressure relief valve and discharge arrangement, its venting and any visible corrosion, and we note the condition of softeners and treatment equipment. When a house shows staining or poor flow, our report says what we saw and where it appears to originate — which is the information you need to decide whether the next call is to a plumber or to the City.
The public supply comes from three alternating wells with a combined pumping capacity of over 800 gallons per minute, and the City states it serves all platted areas.

Utilities and money
This deserves its own section because it is the one item on this page that can cost a buyer real money on day one. In the City’s own words on its water and sewer services page, delinquent water utility bills remain with the property, not the occupant.
The City sets out its authority plainly: it may shut off utilities for nonpayment, charge delinquent bills to the property, and place a lien against the property for unpaid utilities. So the question to ask is not whether the seller has paid, but whether the account attached to the address is clear. Get it confirmed in writing.
Rates as published, effective July 2025, are a ready-to-serve charge of $10.80 a month for water plus $4.54 per thousand gallons, and $26.58 a month for sewer plus $5.81 per thousand gallons, with garbage and recycling at $13.06 a month. The ready-to-serve charge applies whether or not any water is used, and there is a $50 fee when service has to be turned on or off for repairs.
One quirk worth knowing if the property has any outdoor water use. Outside or second meters measure water that does not enter the sanitary sewer, are billed twice a year (both times in June) and carry a $12 annual administrative fee. If there is no outside meter and you have a one-off large use that never reaches the sewer — the City’s own example is filling a swimming pool — contact the City promptly, because a sewer billing adjustment may be available.
None of this is something an inspection reports on. We mention it because it is the kind of thing that is easy to find out before closing and expensive to discover afterwards.

Permits
Building permits and inspections here are handled by the Western Washtenaw Construction Authority, a shared authority covering Freedom Township, Bridgewater Township, Manchester Township and the City of Manchester. It is the permitting and enforcement agency for building work and for soil erosion and sedimentation control across all four.
It sits in the lower level of the Manchester city offices, and it opens Monday, Wednesday and Friday from eight until one, closed Tuesday and Thursday. As with any part-week office, gather your questions and ask them in a single visit. A fee schedule took effect in February 2024 and permit payments can be made online.
The Authority also publishes which code editions are actually in force — the 2015 Michigan Residential Code, the 2015 Michigan Building Code and a 2021 mechanical code among them. That is a rare courtesy. It matters because the standard a house was built or altered to is the standard it is fairly judged against, and knowing the current edition tells you what any new work will have to meet.
A home inspection is not a code inspection and we do not present it as one. We report condition and function, and we flag work that looks as though it was done without the benefit of a permit or an inspection — which on a house with a lot of history is a common finding and a reasonable thing to ask the Authority about.
Ask for the permit history on the specific address while you are there. On a town where roughly 353 units predate 1940, the gap between what was permitted and what is physically present has had a very long time to open up. Commercial building inspections to the CCPIA standard are available where the building is commercial.

Drainage
The City’s own history notes that early settlement here was slow because of boggy ground and tree stumps. That is a nice piece of local color and also a practical hint: ground that held water in 1832 has not necessarily stopped doing so, and low-lying parts of an old settlement are exactly where wet basements concentrate.
The City’s community systems page records that a combined sewer system previously caused stormwater management problems, and that in 1990 the storm sewers were fully separated from the wastewater sewers. It also notes the sanitary system was designed to accommodate moderate growth over a fifteen to twenty year period from 1989, and that it covers most but not all of the platted areas.
For a buyer that translates into two questions. Is this address actually on the public sewer, given the City says most and not all. And on a house that predates 1990, how is the roof and surface water handled now that the two systems are separate?
So we record where the downspouts terminate and whether they carry water clear of the walls or drop it at the foundation, where any sump pump discharges and whether there is a backup arrangement, and how the ground falls away from the building. On a pre-1940 house the original arrangement has usually been altered more than once.
Inside, we look for what water leaves behind: staining and tide lines on foundation walls, efflorescence and mineral deposits, replaced lower wall finishes, and corrosion at the base of mechanical equipment. Equipment sitting up on blocks usually means something happened once, and it is always worth asking about.
Washtenaw County averages around thirty inches of precipitation a year, with about seventy percent of it returning to the atmosphere and the rest going to lakes, streams and groundwater. The share that lands on a roof is the part a homeowner controls.

The housing
Roughly 353 of the housing units here predate 1940 and about 312 were built in the 1990s. The four decades in between produced only around 359 units altogether, so most Manchester houses are either genuinely old or comfortably modern, with relatively little in the middle.
On the pre-1940 stock the questions are about accumulated change. Electrical systems rebuilt in stages by different hands, with mixed wiring types meeting in the same box, ungrounded receptacles, overfilled panels and overfused circuits. Plumbing renewed in part rather than in whole, so the material transitions at the joins are where trouble concentrates. Several generations of roof covering. Heating equipment several replacements from the original. Foundations of stone or early block whose condition depends far more on water management than on original construction.
On the 1990s houses the questions are about timing. Those homes are now thirty to thirty-five years old, which is when the first full round of replacements lands at once: original roof coverings reaching the end of their service life, water heaters on their second or third, furnaces and condensers at the point where the next failure means replacement. Windows are usually original, and failed double-glazing seals show as clouding between the panes. Decks from that era need their ledger connections, flashing, fasteners and post bases genuinely examined, because that is where deck failures start.
The 40% of stock that is not a detached house matters more here than the number suggests. In a small city that usually means converted upper floors above shops, small multi-unit buildings and mixed commercial and residential in the old core. Shared roofs, shared walls and shared services raise questions a single-family inspection does not, and access to common areas has to be arranged rather than assumed. Tell us what the building actually is and we will scope the visit properly.
Radon testing and mold inspection and testing can be added to any visit.

The buried line
The pipe running out from the building belongs to the owner, and no visual inspection reaches inside it. On a house predating 1940 in a town whose sewer arrangement was reworked in 1990, that pipe has had a long and possibly eventful life.
We will not name a material from a build year. No authoritative source establishes what Manchester laterals are generally made of, and a guess in a report is worse than no statement at all.
A sewer camera inspection records what is actually in there: roots, cracks, displaced joints, bellies or blockages where they exist, and a clear run where they do not. In an old platted town with mature street trees, roots are the common finding, and they give no warning until the day the drains back up.
If the address turns out not to be on the public sewer, the camera earns its place a different way: it documents the building drain out to the tank, which is the owner’s pipe and the part a septic evaluation does not examine. Take septic and well questions to the county health department, and start early, because that work runs to its own timetable.
A camera inspection is added to the same appointment rather than booked separately. We deliver a full written report with photographs, generally the same day. You can read what our clients say, browse answers to common questions, or get in touch about a specific address in Manchester — and if you are buying, a buyer’s inspection is the place to start.

Radon in Washtenaw County
Zone 1 is the highest of the three EPA categories — the predicted average indoor level across the county is above the 4 pCi/L action level. What a zone cannot tell you is anything about one house: 38% of tests actually run in Washtenaw County still came back at or above the EPA’s 4 pCi/L action level. The zone describes a county. The only result that describes your basement is the one measured in it.

Reviews
Mr. Cahoon was very thorough inspecting the home I am interested in purchasing. He explained everything clearly as he went along. Went above and beyond crawling into the very small crawl space! Thank you!
I recently hired Trademark for a full home inspection on a new purchase, including sewer scope and radon testing. It was a phenomenal experience from beginning to end. Our inspector, Mitch, did a fantastic job explaining all the findings, and the digital report with photos and videos was superb. Would definitely recommend without hesitation.
We had Mitch inspect our prospective house and he was amazing. He was thorough, patient to answer my questions and provide feedback on what areas he would recommend having a follow up expert and why. The office was responsive and I was able to book multiple services to be done in the same visit (inspection, radon test, sewer scope).
What happens
Questions
The City states that delinquent water utility bills remain with the property, not the occupant, and that it may charge them to the property and place a lien against it. Ask for written confirmation that the utility account for the address is clear before closing.
A city. Its council, clerk and offices are all city ones, and the local construction authority lists the City of Manchester and Manchester Township as separate members. Many people still say village out of habit, so search for city ordinances and city offices.
The Western Washtenaw Construction Authority, a shared authority covering Freedom Township, Bridgewater Township, Manchester Township and the City of Manchester. It sits in the lower level of the city offices and opens Monday, Wednesday and Friday, eight to one.
The City says an odor in the hot water only is usually the magnesium rod in the water heater — a house issue rather than a supply one. If the smell is in both hot and cold, it suggests flushing the system first.
The City explains that flushing and other disturbances loosen deposits in the mains, and that iron bacteria or iron deposits can accumulate in dead-end lines. Running the largest faucet until it clears usually resolves it.
No. The City says the sewage system covers most of the platted areas, with some exceptions. Confirm what the specific address is actually connected to rather than assuming, and if it is on septic, take that to the county health department early.
The storm sewers were fully separated from the wastewater sewers, ending a combined system that had caused stormwater problems and overflows. On a house older than that, the below-ground drainage arrangement may have been altered part way through its life.
Yes. Around 40% of Manchester’s housing stock is not a detached house, and shared roofs, walls and services raise questions a standard single-family inspection does not. Tell us what the building actually is so we can scope it and arrange access properly.
