A damp basement can have several causes, and the buried sewer line is the one a visual inspection cannot check. A scope rules it in or out. More about sewer scope inspections
View a sample reportHarrison Township housing stock
Harrison Township has roughly 12,692 housing units and about 54% of them are single-family detached. Age is the most useful single fact about a house before anyone has seen it. It narrows down what is worth checking first, and it is why two places of much the same size can need quite different inspections.
If the town has a defining decade it is the 1970s, which accounts for 2,798 homes, around 22% of the housing stock. It is also less detached-house territory than most of the area at 54%, so condominiums, duplexes and small multi-family buildings are a bigger share of what we inspect here — and those bring their own questions about what is yours to maintain and what belongs to the association.
The median owner-occupied home here is valued at $241,700. There are around 513 manufactured and mobile homes in Harrison Township. Those are a different inspection — the questions are about the frame, the anchoring and the skirting rather than a basement. Around 614 homes sit in two-to-four unit buildings, where a shared roof, a shared wall and sometimes a shared furnace mean the report has to be clear about where one unit stops.
Treat this as a starting list, not a diagnosis. A Harrison Township home inspector checks these things early in a home of this age and then records what is genuinely there, which is often not what the era would suggest.

When Harrison Township was built
87% of homes here run on utility gas. Another 75 use bottled or LP gas.
Local knowledge
Harrison Township draws the sewer ownership line more clearly than almost anyone, and it is worth knowing before rather than after.
The Township states that it is responsible for cleaning a blockage in the sewer main only, and that the homeowner is responsible for cleaning or removing any blockage in the sewer lead from the building up to the main. Everything between your basement and the street is yours — its condition, its blockages and its repairs.
It is equally direct about what happens after a backup. Under Public Act 222, a written claim must be filed with the Township within 45 days of the overflow or backup being discovered, and the Township says plainly that failure to give that notice will prevent recovery of damages. Forty-five days sounds generous until you are dealing with the mess itself.
The housing is suburban and spread across four decades: of about 12,692 units, 2,798 date from the 1970s, 2,183 from the 1990s, 2,107 from the 1980s and 1,782 from the 1960s. Around 54% is single-family detached, so nearly half of what changes hands here is attached housing.
Before you buy
The sewer lead
Most municipalities describe this vaguely if at all. Harrison Township puts it in two sentences.
On its sanitary sewer backup guidelines, the Township asks that you call the Water and Sewer Department during business hours or the after-hours emergency line, and a representative will respond to determine whether the main is blocked. If it is, the Township clears it. If the blockage is in the lead running from the building to the main, that is the homeowner’s to clear.
And then the claim clause. In compliance with Public Act 222, a written claim must be filed with the Township within 45 days after an overflow or backup is discovered, and failure to provide that notice will prevent recovery of damages. That is the Township’s wording, not ours, and it is the plainest statement of the consequence we have found in any municipality.
Put the two together and the practical conclusion is straightforward: the pipe you are about to own is the pipe most likely to cause the problem and least likely to be somebody else’s to fix. Knowing its condition before closing is not an upsell, it is arithmetic.
The Township’s system is substantial — 117 miles of water main and 89 miles of sewer line serving around 9,700 customers, with a population of 24,317 at the 2020 Census — and the Township is a regulated MS4 community with a published storm water plan, working alongside the Clinton River Watershed Council.
If you are planning work
If your reason for buying involves getting work done soon after closing, the Township publishes exactly what you need to plan around.
On the Building Department pages, inspections run by trade on fixed days: building Monday through Friday; mechanical Monday, Wednesday and Friday from late morning to early afternoon; plumbing Monday, Wednesday and Friday mornings; and electrical Monday and Friday afternoons.
There is also a published window for questions. Inspectors take them in the Building Department between 8:00 and 8:30 in the morning — the code enforcement and building inspector Monday to Friday, the plumbing inspector on Monday, Wednesday and Friday, with the mechanical and electrical inspectors reached by voicemail. Outside that half hour, the Township asks that you leave a message.
The department inspects any construction for which a permit is taken out, covering building, plumbing, heating and electrical work, and asks that you contact it if you are unsure whether a permit exists or is required. That is a useful call to make about a property you are considering, and it is free.
What the record cannot tell you is condition. That is a buyer’s inspection: the roof, structure, foundation, drainage, electrical, heating and cooling, plumbing and accessible interior, with what is failing, what is near the end of its service life, and what to plan for.
Attached housing and four decades of building
With around 54% single-family detached, close to half of what sells here is a condominium, a townhouse or something else with shared structure — and that changes the first question of the inspection.
On attached housing, work out which components are yours and which belong to the association before the appointment. Roof, siding, windows and sometimes the water heater or furnace flue can fall to either side depending on the governing documents, and that line decides who pays for what we find. Having the documents in advance changes how you read the report rather than what is in it.
On the detached side the housing runs from the 1960s to the 2000s with no single dominant decade. A 1975 house has been through at least one full round of roof, furnace, air conditioning and water heater replacements. A 1995 house is thirty years old and coming due for its first. A 1965 house has had two.
We do not name components from a build year. We report what is installed, its condition, what is at or past the end of its service life, and what could not be seen — and we say plainly where something was inaccessible rather than guessing at it.
The buried line
Everything on this page comes back to the same component, because the Township itself keeps pointing at it.
On a house from the 1970s the lead running from the building to the sewer main has been in the ground fifty years or more, and on a 1960s house sixty — long enough for roots to find a joint, for ground movement to displace a section, or for a repair to have been made that nobody now remembers. We will not name a material from a build year, because no authoritative source establishes what Harrison Township leads are generally made of.
A sewer camera inspection records what is actually inside — roots, cracks, displaced joints, bellies or blockages where they exist, and a clear run where they do not — and it is added to the same visit rather than booked separately. Given what the Township says about who clears a blockage in that lead, it is a straightforward piece of due diligence here.
Alongside it, commercial building inspections follow the CCPIA standard for offices, retail, multifamily and warehouse property, and radon testing or mold inspection and testing can be added to a residential or commercial visit.

Radon in Macomb County
Zone 3 is the lowest of the three EPA categories — the predicted average indoor level across the county is below 2 pCi/L. So on the state’s map Harrison Township sits well away from the worst of it, and we are not going to dress that up into something it is not.

Reviews
Mitch did our inspection for the sale of our home and he was professional, efficient and friendly. The report was sent to me and my agent in a timely fashion and I appreciated how quickly the appointment was made and everything was finished! Would recommend to others.
Kendra AllenRoseville, MII 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.
Salina HamiltonOak Park, MIWe 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).

Questions
It depends where it is, and the Township is explicit. It is responsible for cleaning a blockage in the sewer main only; the homeowner or resident is responsible for cleaning or removing any blockage in the sewer lead running from the building up to the main. Call the Water and Sewer Department during business hours or the after-hours emergency line, and a representative will respond to determine whether the main is blocked.
Forty-five days, and the Township states the consequence bluntly. In compliance with Public Act 222, a written claim must be filed with Harrison Township within 45 days after the overflow or backup was discovered, and failure to provide the required notice will prevent recovery of damages. Photograph everything, keep receipts, and get the notice in early rather than late.
On fixed days by trade. Building inspections run Monday through Friday; mechanical Monday, Wednesday and Friday from late morning to early afternoon; plumbing Monday, Wednesday and Friday mornings; and electrical Monday and Friday afternoons. Inspectors take questions in the Building Department between 8:00 and 8:30 in the morning, with mechanical and electrical reached by voicemail. If a plan depends on several trades signing off quickly, sequence it rather than assuming it.
Ask the Building Department. It inspects any construction for which a permit is taken out — building, plumbing, heating and electrical — and specifically invites you to contact it if you are unsure whether a permit exists or is required. It is a free call and worth making about a property you are considering. Bear in mind that a permit on file does not establish that work is sound today, and nothing on file does not establish it was done badly.
Spread across four decades. Of about 12,692 housing units, 2,798 were built in the 1970s, 2,183 in the 1990s, 2,107 in the 1980s and 1,782 in the 1960s, with 1,160 from the 1950s and 1,052 from the 2000s. Around 54% is single-family detached. Because no decade dominates, assumptions about age do not travel — a 1965 house has had two rounds of mechanical replacements, a 1995 house is coming due for its first.
Which components are yours. With nearly half the township’s housing attached, this is the most common question we get here — the roof, siding, windows and sometimes the water heater or furnace flue can fall to either the owner or the association depending on the governing documents. Getting those documents before the inspection changes how you read the report rather than what is in it.
The Water and Sewer Department reports maintaining 117 miles of water mains and 89 miles of sewer lines for approximately 9,700 customers, serving 24,317 residents as of the 2020 Census. The Township is also a regulated MS4 community with a published storm water plan and works with the Clinton River Watershed Council on community education.
Here more than most places, because the Township has already told you the lead is yours. On a 1970s house that pipe has been in the ground fifty years or more, and no visual inspection reaches inside it. We will not guess a material from a build year — no authoritative source establishes what leads here are generally made of. Putting a camera down the line documents roots, cracks, displaced joints, bellies or blockages where they exist, and is added to the same appointment.
