The other things worth testing while somebody is already there.
Carried out after remediation on the treated area and the areas next to it, to confirm what was found. More about mold inspection and testing
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 reportMarysville housing stock
Marysville has roughly 4,632 housing units and about 66% 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 1970s than from any other decade — 1,120 homes, roughly 24% of the town.
The median owner-occupied home here is valued at $167,700. 86% are owner-occupied, which is high even for this area. There are around 329 manufactured and mobile homes in Marysville. Those are a different inspection — the questions are about the frame, the anchoring and the skirting rather than a basement.
This is not a forecast for any one address. It is where a Marysville 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 Marysville was built
85% of homes here run on utility gas. Another 63 use bottled or LP gas.
Local knowledge
Marysville publishes something no other municipality in this project does: an online map where you can enter an address and see what the City believes the water service line is made of — at four separate points along its length, and whether each of those is verified or merely inferred.
That exists because of the state’s lead and copper rules. Michigan adopted its current provisions in June 2018, and every water system had to submit a Complete Distribution System Materials Inventory to the state by 16 October 2024, detailing the material of every service line in its distribution system. Marysville completed and filed its inventory, and is required to keep it available for public viewing.
The four points are worth knowing because they are the places a service line changes hands and changes material: inside the house at the meter connection, outside on the private side of the curb stop box, outside on the public side of the same box, and out at the connection to the water main. A line can be copper at one and something else at another.
For a buyer, that means a real answer is available before you make an offer — not a guess from a build year, and not from us. Look the address up.
The housing is mostly late-century: of about 4,632 units, 1,120 date from the 1970s and 817 from the 1980s, with 651 from the 1990s and 204 predating 1940. Around 66% is single-family detached.
Before you buy
The service line inventory
The City’s water service line program document explains its own categories, and the distinctions matter.
A material marked verified has actually been looked at, and needs nothing further. A material marked inferred was predicted from other similar information — the state allowed random physical verifications to be used to predict materials across the rest of a system — and a resident who knows better can submit evidence to correct it. And a material classified as unknown, potentially lead, is one that could not be predicted at all, which means some or all of the line could be lead, or galvanized pipe previously connected to lead.
That last category carries an obligation on the City: annual notification to the resident, every year, until the material is known. If you are buying a property in that category, the notices will keep arriving until somebody establishes what is down there.
The route to establishing it is published. A resident can go to the viewer, look up the address, and use the resident submission tutorial to determine and submit what is in their own home — a submission the City’s consulting engineer then reviews. Or they can call the Public Service Department and schedule an appointment with a City inspector.
The outside half is not a homeowner job. The City states that outside materials are determined by a qualified contractor and require one or two excavations on each side of the curb box, roughly twelve inches across and four to five feet deep, with that work running from spring 2025 through summer 2026. If you see holes near the sidewalk on a Marysville street, that is what they are.
Our own role here is narrow and worth stating. We do not test water — that is a separate discipline with its own certified laboratories. What an inspection reports is the visible supply piping where it is accessible, including at the point the service enters the building and along exposed runs, and whether visible piping appears to be galvanized rather than copper or plastic. That is point one of the City’s four, and it is the one you can see without digging.
Who pays
Almost every buried pipe in this project belongs to the property owner, and almost every page we write says so. Marysville publishes an exception worth knowing about.
The City states that all portions of the service line containing lead — or galvanized pipe previously connected to lead — must be replaced at the water supply’s expense. That covers the portion the water system owns and the homeowner’s portion.
This is a state-wide framework rather than a Marysville invention, and it is the opposite of how the sanitary lateral works. On the waste side the owner typically owns the pipe from the building to the main and pays for whatever happens to it. On the lead water service side, replacement is the supply’s cost.
For a buyer the practical consequence is that a lead classification on the City’s inventory is not the liability it might first appear. It is a scheduling question and a water-use question rather than a bill you inherit. What it does mean is that you should know which category the address falls in, read whatever notices the City has sent, and follow the state’s guidance on reducing exposure in the meantime — running the tap after water has stood, using cold water for drinking and cooking, and a certified filter where appropriate.
None of that is something a building inspection answers, and we will not pretend otherwise. The City’s inventory and its published resources are the authoritative source.
Permits
Marysville’s Building Department runs plan reviews and issues building, electrical, mechanical and plumbing permits itself, then inspects the work. That is worth knowing when you are researching a property: unlike several townships in this project, everything is in one place.
The definition of what needs a permit is the broad one taken straight from the construction code, and it is worth reading against any house you are considering. Permits are required to construct, enlarge, alter, repair, move, demolish or change the occupancy of a building or structure — and to erect, install, enlarge, alter, repair, remove, convert or replace any electrical, gas, mechanical or plumbing system.
Read that list next to what previous owners typically do to a 1970s or 1980s house and it covers most of it: the furnace, the water heater, the service upgrade, the basement, the addition, the deck. The Building Official is also the code enforcement officer and the planning and zoning administrator, which for a city this size means one person holds the whole picture and is the right person to ask.
What an inspection adds is condition rather than compliance. A buyer’s inspection covers the roof, structure, foundation, drainage, electrical, heating and cooling, plumbing and the accessible interior. On the largest slice of this city — 1,120 houses from the 1970s and 817 from the 1980s — the recurring theme is second-generation equipment: the original furnace and water heater are long gone, what replaced them is now itself aging, and the interesting question is how well that replacement was done.
The city code carries the rest, and the City runs its own water and wastewater treatment plants.
The other buried line
Having established that a lead water service is replaced at the supply’s expense, the sanitary lateral is worth a paragraph of contrast, because it works the other way.
That pipe runs from the building to the sewer main, it is normally the owner’s responsibility, and it is the one component no visual inspection reaches. On a 1970s house — the largest single slice of Marysville — it has been in the ground fifty years, with the landscaping planted at construction now fully mature above it. On one of the 204 prewar units here, far longer.
That is 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 Marysville laterals are generally made of.
It is also the one buried line the City is not inventorying. There is no public map of sanitary laterals, no four-point verification and no program to replace them. The only way to know is to look.
A sewer camera inspection records what is actually inside the line: roots, cracks, displaced joints, bellies or blockages where they exist, and a clear run where they do not. It is added to the same visit rather than booked separately. 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.

Reviews
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.
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).
Chris PlaweckiOak Park, MIThis is one of the finest companies I have come across - that means serious customer service and professionalism. Justin was the inspector and he was very thorough yet very kind to answers all the questions that came in my mind during inspection. He took enough time, no rush, and a very detailed inspection was conducted. Extremely competitive pricing and timing from the company. 100% recommend to anyone looking for any kind of property inspection!!

Questions
Yes, and Marysville makes it easier than most. The City publishes an online Water Service Line Viewer: enter an address and it shows the material recorded at four points — inside at the meter connection, outside on the private side of the curb stop box, outside on the public side, and at the connection to the water main — along with whether each is verified or inferred.
Verified means the material has actually been looked at. Inferred means it was predicted from other similar information, which the state allowed water systems to do from a sample of physical verifications — and a resident who knows better can submit evidence to correct it. Unknown, potentially lead, means it could not be predicted at all, and carries annual notification from the City until the material is established.
The water supply. The City states that all portions containing lead, or galvanized pipe previously connected to lead, must be replaced at the water supply’s expense — including the homeowner’s portion. That is the opposite of how the sanitary lateral works, where the owner normally owns and pays for the pipe from the building to the main.
Service line verification. The City states that outside materials are determined by a qualified contractor and require one or two excavations on each side of the curb box, roughly twelve inches across and four to five feet deep, and that this work runs from spring 2025 through summer 2026. The material has to be checked on each side of the box because it can change there.
No. Water testing is a separate discipline with its own certified laboratories, and the City’s inventory and published resources are the authoritative source for service line material. What an inspection reports is the visible supply piping where it is accessible — including where the service enters the building — which is the one of the City’s four points you can see without digging.
The City. Its Building Department conducts plan reviews and issues building, electrical, mechanical and plumbing permits itself, then inspects the work — so unlike several townships in this region, the whole record is in one place. Permits are required to construct, enlarge, alter, repair, move, demolish or change the occupancy of a building, and to install, alter, remove, convert or replace any electrical, gas, mechanical or plumbing system.
Mostly late twentieth century. Of about 4,632 housing units, 1,120 date from the 1970s and 817 from the 1980s, with 651 from the 1990s, 473 from the 1960s and 204 predating 1940. Around 66% is single-family detached. On that stock the recurring theme is second-generation equipment — the original furnace and water heater are long gone, and what replaced them is now aging in turn.
Yes, and it is the buried line nobody is inventorying. Unlike the water service, there is no public map of sanitary laterals and no program to replace them — and the owner normally owns that pipe. On a 1970s house it has been in the ground fifty years with mature landscaping above it. Putting a camera down the line documents roots, cracks, displaced joints, bellies or blockages where they exist, and is added to the same appointment.
