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

Hazel Park has roughly 7,256 housing units and about 87% 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 1950s, which accounts for 2,076 homes, around 29% of the housing stock.
The median owner-occupied home here is valued at $129,300.
Treat this as a starting list, not a diagnosis. A Hazel Park 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.
Housing figures: US Census Bureau, American Community Survey 2022 five-year estimates.
When Hazel Park was built
86% of homes here run on utility gas, and 22 still heat with oil. If yours is one of them, the tank is the thing to ask about — where it is, and whether it was ever buried. Another 173 use bottled or LP gas.
Local knowledge
Hazel Park is a small, dense, old city of detached houses, and the age of the housing is the single most useful thing to know about inspecting here.
Of roughly 7,256 housing units, about 21% predate 1940, 13% date from the 1940s and 29% from the 1950s — something like 63% built before 1960 — with a median build year of 1956 and around 87% single-family detached. Almost everything here is a whole house, and most of it has been standing for seventy years or more.
On housing that old the build year stops being informative. Everything with a shorter service life has been replaced, repaired or left running past its design life, usually in some combination nobody has a complete record of. We will not reason from the year to what is installed — the only reliable way to know is to look at the house.

Before you buy
Seventy years on
With roughly 63% of the city built before 1960 and 21% of it before 1940, this is a housing stock that has been through several complete cycles of replacement.
A roof, a furnace, a water heater and windows all have service lives far shorter than seventy years, so each has been renewed at least once or is running well past its design life. The electrical service and supply plumbing have had the same period to be extended, altered or partly replaced, often by different hands at different times.
Two houses of the same age on the same street can therefore be entirely different by now. Some have been comprehensively updated; others have original components still in service. A home buyer inspection establishes which — reporting the roof, structure, foundation, drainage, electrical, heating and cooling, plumbing and the accessible interior, photographed and written up with how urgent each finding is, and saying plainly what could not be reached.

Heating
Among the forms the Building Department publishes is a furnace and heating plant inspection record. Several communities in this region ask for something similar, and they tend to be the ones with older housing.
It is worth being precise about what such a record establishes. A contractor inspecting a furnace is answering whether the equipment is safe to operate at that moment. That is a useful thing to know and not the same as a condition assessment — a heating system can be signed off as safe and still be within a year or two of replacement.
An inspection answers the broader question: what condition the equipment is in, how old it is, how the installation looks, whether the venting is right, how it performs on the day, and roughly how much service life is left. On a house with a median build year of 1956, the gap between those two answers is where a buyer most often gets caught out.
The department also handles permits for building, electrical, mechanical, plumbing, right-of-way and sign work, and registers contractors. Permit history is worth checking on a property of this age, with the usual caution: a permit does not establish that work is in good condition today, and nothing on file does not establish that it was done badly.

Rentals
The Building Department is responsible for conducting all rental inspections in the city, alongside business inspections and inspections of tagged buildings.
We found no residential point-of-sale requirement here of the kind several Downriver cities operate. Confirm the position for a specific address with the department rather than relying on our search — municipal requirements change and this is worth a phone call. But where none applies, the inspection you commission is the only one examining the house on your behalf.
What we assess outside the building is how it manages water: accessible grading, gutters and downspouts and where they discharge, foundation conditions, the basement or crawlspace and sump equipment where present, documented as found. On a small lot in a dense older city, where the water goes matters more than people expect. Radon testing and mold inspection and testing can be added to the same appointment.

The buried line
On a housing stock where a fifth of the properties predate 1940, the private sewer lateral is one of the least known things about any of them.
It runs underground from the house to the public system and no visual inspection can see inside it. Seventy years or more is ample time for tree roots to find a joint, for ground movement to displace a section, or for repairs to have been made that nobody now remembers. We will not name a material from a build year, because no authoritative source establishes what Hazel Park laterals 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. It is added to the same visit. Alongside it, commercial building inspections follow the CCPIA standard for offices, retail, multifamily and warehouse property.

Radon in Oakland County
Zone 2 is the middle EPA category — the predicted average indoor level across the county sits between 2 and 4 pCi/L. What a zone cannot tell you is anything about one house: 29% of tests actually run in Oakland County still came back at or above the EPA’s 4 pCi/L action level. Zones are drawn around counties, not around addresses, which is why the only number that settles the question is the one from the house itself.

Reviews
Would recommend using Trademark Inspection Services. Ora was our inspector; he was thorough, knowledgeable and personable. His report was timely and informative. This put us at ease knowing we could be the most informed about the property.
Kurt did a fantastic job with our home inspection today! He was extremely thorough and took the time to explain everything in a way that was easy for me to understand. I really appreciated his patience and professionalism throughout the entire inspection. He answered all of my questions and gave me a much better understanding of the home, which gave me a lot of confidence moving forward with my house purchase. I highly recommend Kurt to anyone looking for a knowledgeable, thorough, and trustworthy home inspector!
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.
What happens
Questions
Older than most of the region. Of roughly 7,256 housing units, about 21% predate 1940, 13% date from the 1940s and 29% from the 1950s — something like 63% built before 1960 — with a median build year of 1956 and around 87% single-family detached. Most houses here have been standing seventy years or more, which means everything with a shorter service life has been replaced, repaired or left running. Which applies to a particular house is not something the build year can tell you.
The Building Department publishes a furnace and heating plant inspection record, and several communities in this region with older housing do something similar. Worth understanding what it establishes: a contractor inspecting a furnace is answering whether the equipment is safe to operate at that moment. That is not a condition assessment. A heating system can be signed off as safe and still be close to the end of its service life, which is the question an inspection answers.
We found no residential point-of-sale requirement of the kind several Downriver cities operate. The Building Department is responsible for conducting all rental inspections, alongside business and tagged building inspections. Confirm the position for a specific address with the department rather than relying on our search — municipal requirements change. In the meantime, plan on your own inspection being the one examining the house on your behalf.
The Building Department publishes a contractor registration form, so contractors working in the city register with it. If you are choosing between quotes after an inspection, asking whether a contractor is registered with the City is a straightforward check. The department also handles permits for building, electrical, mechanical, plumbing, right-of-way and sign work, so most home improvement projects of any substance will involve it.
The Building Department conducts all rental inspections in the city, alongside business inspections and inspections of tagged buildings. If you are buying a let property or intending to let one, that inspection regime is part of what you take on, and the department is the place to confirm where a particular property stands. Knowing the condition of the roof, heating, electrical and plumbing before you close is what tells you how comfortably a property will meet a compliance standard.
On this housing stock it is worth serious consideration. With around a fifth of properties predating 1940 and 63% built before 1960, many private laterals here have been in the ground seventy years or more. The line is buried, no visual inspection can see inside it, and we would not guess a material from a build year — no authoritative source establishes what Hazel Park laterals 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.
