View a sample reportGrand Blanc housing stock
Grand Blanc has roughly 3,538 housing units and about 53% of them are single-family detached. Homes built in a single stretch tend to wear out in the same places at the same time. That is why when somewhere was built is the first thing worth knowing about it.
The busiest stretch of building here was the 1970s: 937 homes, about 26% of everything standing today. It is also less detached-house territory than most of the area at 53%, 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 $229,300. Only 55% of occupied homes are owner-occupied, so a good share of what we inspect here is bought as a rental or sold with tenants in place — which changes what access on the day looks like.
None of this says anything about the specific house you are buying. It is the shortlist a Grand Blanc home inspector works through in a home of this age, and every item on it gets photographed and written up whichever way it turns out.

Local knowledge
The City of Grand Blanc makes its own water. It draws from its own groundwater wells, runs it through a reverse osmosis plant, tests it daily, and states plainly on its own website that the supply has no connection to the Flint River or the Flint water system.
One detail in the City’s explanation of how that plant was paid for is worth more to a homeowner than the rest put together: the reverse osmosis process has the added benefit of softening the water. Municipally softened water is genuinely unusual, and it changes what a household water softener in the basement is actually there for.
The second thing to know is the age profile, which is unusually concentrated. Of roughly 3,538 units, 937 date from the 1970s and 902 from the 1960s — 52% of the entire housing stock in two decades — with barely a hundred units built since 2000. About 53% is single-family detached.
That is a specific kind of house with a specific set of questions, and it is the sort of stock where the electrical system in particular has usually been through more than one round of change.
Unlike several nearby cities, Grand Blanc issues all four kinds of permit itself — building, plumbing, electrical and mechanical — so a property’s permit history sits in one place rather than being split with the State.
Before you buy
Water
Very few communities we cover treat their own water to this extent. The City’s water and sewer page describes groundwater wells, its own treatment plants, daily testing and reverse osmosis filtration before the water reaches homes and businesses.
The plant was funded by a debt millage approved by voters in 2001. When falling taxable values stopped the millage covering the bond payments, the Water Fund absorbed the difference until 2012, at which point a capital charge was introduced. That history explains the structure of the bill, which carries two separate ready-to-serve charges — one for water and one for sewer — payable regardless of how much you use, plus a garbage charge, with usage billed per hundred cubic feet on top.
Billing is bimonthly and the schedule has a lag worth noting: bills go out on the 21st of one month and are due on the 10th of the month after next, with a penalty applied after that. The City accepts payment arrangements on past due accounts, which is worth knowing exists.
The softening is the part that shows up during an inspection. Where the supply arriving at the house is already soft, a water softener in the basement is doing something different from what it would do on a private well, and it may have been installed long before the plant existed or carried over by habit. We report the presence and visible condition of water treatment equipment, its plumbing arrangement, and whether it appears to be in service or bypassed — we do not test water or evaluate treatment performance, and water testing goes through a certified laboratory.
Soft water also has ordinary consequences worth understanding rather than worrying about: it behaves differently in fixtures, appliances and water heaters than hard water does, and a buyer moving from a well or from a hard-water community will notice the difference.
Electrical
The Building Department publishes a note about a change that took effect on 12 March 2024. Michigan adopted the 2023 National Electrical Code, and electrical permits applied for after that date must also meet the emergency service disconnect requirement for one and two family dwellings. Where a building permit was issued before that date, the earlier code editions still apply.
The practical effect of an emergency service disconnect requirement is a means of cutting power to a house from outside it, reachable without entering the building. On new work and service replacements it is now part of the job.
On existing houses it is not retroactive, and we do not report older installations as violations for lacking something that was not required when they were done. What we do report is what is actually there and what condition it is in.
That matters here because of the age profile. On a house from 1968 or 1974, the original service was sized for a very different household. Most have been upgraded; many have had circuits added in stages by different hands; some carry original distribution behind a newer panel. The panel itself is often the clearest single indicator of how a house has been looked after — whether circuits are labeled, whether the work inside is orderly, whether obvious corners have been cut.
A buyer’s inspection covers the service, the panel and the accessible branch circuit wiring, along with the roof, structure, foundation, drainage, heating and cooling, plumbing and the accessible interior. We are not a code inspection and do not issue citations, but we say plainly where something looks wrong or unsafe.
Permits
Grand Blanc keeps the whole permit process in house. There are separate applications for building, plumbing, electrical and mechanical work, plus a contractor registration form and a zoning compliance application covering fences, sheds, retaining walls and detached accessory structures. The three trade applications can now be submitted online for a small fee, with paper applications still accepted by email, mail or in person.
For anyone researching a property, that arrangement is the friendliest of the ones we come across. A single records request at city hall should produce the roof, the addition, the deck, the furnace, the water heater, the service upgrade and the re-pipe together, rather than sending you to a county office or a state database for half of it.
The Building Department also issues certificates of occupancy and enforces the building codes, and the City publishes its residential and non-residential building regulations by zoning classification along with separate setbacks for the central business district.
It is worth pulling that file on any property here where something has obviously been altered. On sixties and seventies housing the common candidates are a finished basement, a converted garage, an added bathroom, a deck and a replaced furnace — and where the paperwork exists, it tells you the work was seen by somebody whose job it was to look.
Trees
The Department of Public Works publishes two lists for planting in the City right-of-way: the species it approves, and the species it says should be avoided. Permission from the DPW Director is required before planting either way.
The criteria the City sets out are sensible and mostly about the street: how large the mature tree will be, whether it will crowd other trees or structures, whether it will obstruct a driver’s view, whether it is prone to pests, whether it drops litter, and whether it adds variety to the area.
The avoid list is the interesting one. Willow, poplar, silver maple, elm, sycamore, birch, mulberry and tree of heaven all appear on it. The City does not give a reason species by species, but several of those are the trees best known for fast, aggressive, water-seeking root systems — and a water-seeking root system is exactly what finds a cracked joint in a buried drain line.
On a walkthrough it is worth looking up as well as down. A mature willow or silver maple standing over the line between the house and the street is not a reason to walk away from a property, but it is a very good reason to find out what is happening underneath it before you commit.
The same trees are worth noting for what they do above ground: limbs over a roof, shade that keeps a roof slope damp, roots lifting a drive or a walk, and debris in gutters that never quite clear. We report all of that as part of the exterior.
The buried line
The drain line from the building to the main belongs to the property owner. On a house built in 1968 or 1974 — which describes just over half the housing in this city — that pipe has been in the ground for fifty years or more, under a lot whose planting has had the whole of that time to mature.
We will not name a material from a build year, because no authoritative source establishes what Grand Blanc laterals are generally made of, and a guess in a report is worse than no statement at all.
What matters is not the material anyway but the condition, and the only way to establish that is to look inside. A sewer camera inspection records roots, cracks, displaced joints, bellies or blockages where they exist, and a clear run where they do not. It is added to the same appointment rather than booked separately.
Alongside it we offer radon testing, mold inspection and testing, and commercial building inspections to the CCPIA standard for offices, retail, multifamily and warehouse property — which comes up regularly in a city where roughly 47% of the housing is something other than a detached house.

Desmond SheppardFlint, MINoah Scott was very thorough and explaining things to us, especially in regard to a possible mold problem.
Claudette GranvilleFlint, 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.

Questions
The City has its own groundwater wells and treatment plants. It states that the water is tested daily and filtered through a reverse osmosis system before reaching homes and businesses, and that it does not come from the Flint River or the Flint water system. Annual water reports are posted on the City website.
Yes. In explaining the capital charge on the bill, the City notes that the reverse osmosis plant approved by voters in 2001 has the added benefit of softening the water. That is unusual for a municipal supply, and it is worth knowing when you find a water softener in the basement of a house you are buying.
That is a question for you and a plumber rather than for us, but the starting point is that the supply arriving at the house is already treated. On an inspection we report the presence and visible condition of water treatment equipment, how it is plumbed, and whether it appears to be in service or bypassed. We do not test water or evaluate treatment performance.
The City notes that Michigan adopted the 2023 National Electrical Code effective 12 March 2024, and that electrical permits applied for after that date must also comply with the emergency service disconnect requirement for one and two family dwellings. Where a building permit was issued before that date, the earlier code editions apply.
The requirement applies to permits applied for after March 2024 rather than retroactively to existing installations. We do not report an older service as a violation for lacking something that was not required when it was installed. We report what is actually there and what condition it is in.
All in one place. The City issues building, plumbing, electrical and mechanical permits itself, along with zoning compliance for fences, sheds, retaining walls and detached accessory structures. That makes a single records request at city hall considerably more useful here than in communities that split the trades out to the State.
There are two ready-to-serve charges each billing cycle, one for water and one for sewer, payable regardless of usage, plus a garbage charge, with consumption billed per hundred cubic feet. Billing is bimonthly, bills go out on the 21st and are due on the 10th of the month after next, and a penalty applies after the due date. The City accepts payment arrangements on past due accounts.
On this housing stock it is usually worth it. Just over half the city was built in the 1960s and 1970s, so the lateral has typically been in the ground fifty years or more, and the City’s own list of trees to avoid planting includes several species best known for aggressive water-seeking roots. A camera inspection documents the actual condition and is added to the same visit.
