Mold and Radon Testing in Leoni Township

Add either to a Leoni Township home or commercial inspection, or book it on its own. We test and we never remediate, so there is nothing to sell you on the back of a result — the number you get is just the number.

How each one works

Radon measured in house on a professional continuous monitor; mold samples to an accredited laboratory:

  • Radon: 48-hour continuous monitor, read on site
  • No mail-in radon kit and no waiting on a laboratory
  • Mold: laboratory results in one to three business days
  • Either can go on the same visit as the inspection

  • Post-remediation mold verification

    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

  • Sewer camera inspections

    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

Leoni Township housing stock

The median Leoni Township home was built in 1966

Leoni Township has roughly 5,884 housing units and about 88% 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.

The other numbers

The median owner-occupied home here is valued at $164,600. 85% are owner-occupied, which is high even for this area. There are around 300 manufactured and mobile homes in Leoni Township. Those are a different inspection — the questions are about the frame, the anchoring and the skirting rather than a basement.

  • Original sewer lateralsWhether the line is still original, and what it is made of, are not questions the build year answers. A scope on the same visit is the cheapest way to see inside it.
  • Aluminum wiring, from about 1965Aluminum branch wiring went into many homes built from roughly 1965. In houses at the later end of this decade it is specifically something to identify.

Treat this as a starting list, not a diagnosis. A Leoni 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.

  • Pre-194018%
  • 1940s9%
  • 1950s16%
  • 1960s12%
  • 1970s13%
  • 1980s5%
  • 1990s12%
  • 2000s14%
  • 2010s<1%
  • 2020s<1%

79% of homes here run on utility gas, and 40 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 462 use bottled or LP gas.

Local knowledge

What makes inspecting a Leoni Township property different?

Leoni Township is currently publishing a public notice about lead in drinking water, and the first thing to say about it is what the Township itself says: this is a corrosion control measure, not a verdict on every tap in the township.

The Township sampled ten homes. The lead 90th percentile came back at 19 parts per billion, above the Action Level of 12 ppb, with two of the sampled sites over the Action Level. The notice is explicit that the Action Level is a measure of corrosion control effectiveness and is not a health-based standard — while also being clear that the goal for lead in drinking water is zero.

What the exceedance triggers is process: educational outreach, sampling every six months at twenty sites, work toward a corrosion control treatment strategy, and replacement of service lines. The Township states the exceedance is resolved after two consecutive six-month rounds below the action levels. Because that sampling is ongoing, the figures above are the round the Township published rather than the last word — ask the Township where things currently stand.

The relevance to a property here is direct, because the Township’s own first piece of advice is to find out what your service line is made of. The housing stock makes that a live question: of about 5,884 units, 4,338 — roughly 74% — were built before 1990, and 1,030 predate 1940 altogether.

Before you buy

Buying a property in Leoni Township? Pay attention to these four things

  • Find out what the service line is made of

    The Township asks residents to determine whether the line from the main is lead, galvanized or another material, through the Township or a licensed plumber.
  • Three quarters of the stock predates 1990

    Which matters because state guidance flags copper plumbing with lead solder from before 1988, and fixtures sold before 2014, as reasons to filter.
  • The sewer ordinance expects the old line to be tested

    Leoni allows an existing building sewer to serve a new building only after examination and test. The Township treats the buried line as something to check.
  • Septic is restricted where sewer is available

    Connection is required within 180 days of notice where a public sewer passes within 200 feet. Establish what the property is on, and what it will be on.

Lead in drinking water

What the Township asks residents to do, and what an inspection can contribute

The Township’s public notice is a good piece of plain writing and worth reading in full. Its practical advice comes down to a few things.

First, learn what your service line is made of — lead, galvanized, or something else — through the Township or a licensed plumber. Second, use a filter certified to NSF/ANSI Standard 53 for lead reduction and Standard 42 for particulates if the home has, or may have, lead or galvanized plumbing, a lead service line, copper plumbing with lead solder from before 1988, or faucets and fittings sold before 2014. Third, flush the tap before drinking or cooking — thirty seconds to two minutes without a lead service line, at least five minutes with one. Use cold water; boiling does not remove lead; clean the faucet aerator.

We want to be exact about our own role here. We do not test water. Water testing is a separate discipline with its own certified laboratories, and the Township points to the state’s list of them. Nothing in a building inspection is a substitute for a water test.

What an inspection contributes

What an inspection does contribute is directly relevant to the Township’s first question. Where the supply piping is accessible — typically at the point the service enters the building, and along exposed runs in a basement or crawlspace — we report what the visible piping appears to be, and we note where visible supply piping is galvanized rather than copper or plastic. That is an observation of what can be seen, not a laboratory finding and not a determination of what is buried beyond the wall. But on a house where nobody has ever looked, it is a useful starting point for the conversation the Township is asking people to have.

Given the age profile here — three quarters of the stock built before 1990, and a fifth of it before 1940 — the plumbing history of an individual house is worth understanding properly rather than assuming. A buyer’s inspection covers the roof, structure, foundation, drainage, electrical, heating and cooling, plumbing and the accessible interior, and reports the plumbing as it is found.

The sewer ordinance

A township that expects the old line to be examined and tested

Leoni Township’s sewer use regulations contain a provision we have not found stated this plainly anywhere else. Section 38-127 allows old building sewers, or portions of them, to be used in connection with new buildings — but only when they are found, on examination and test by the inspector, to meet all the requirements of the division.

Read that as a statement of principle and it is exactly the argument for looking inside a buried line rather than assuming it. The Township does not take an existing lateral on trust. It expects the pipe to be examined and tested before it carries anything new.

What is specifically permitted

The same section is unusually specific about what is permitted. Section 38-127 names vitrified clay, asbestos cement, extra heavy cast iron soil pipe, concrete sewer pipe, ABS extra strength solid wall plastic and PVC to ASTM D-3034 DR-35, and requires cast iron in filled or unstable ground unless the pipe is laid on an approved bed or cradle. Residences need a minimum four-inch pipe, average commercial six-inch, at a fall of one eighth of an inch per foot. Joints and connections must be made gastight and watertight, and a separate, independent building sewer is required for every building, with a narrow exception for a rear building on an interior lot.

That list is worth knowing because it describes the range of what may be under a property here — clay, cast iron, concrete, asbestos cement and plastic have all been permitted at different times. It does not tell you which one is under any particular house, and neither will a build year. The only thing that answers that question is looking.

One more line matters to a buyer: all costs and expenses incidental to the installation and connection of the building sewer are borne by the owner. The pipe is yours, and so is what happens to it.

Sewer or septic

The 200-foot rule and the 180-day clock

Section 38-125 sets out when a property has to be on the public sewer, and the terms are firmer than most.

Where a public or combined sewer runs in an abutting street, alley or right-of-way, and passes not more than 200 feet at the nearest point from a structure in which sanitary sewage originates, the owner is required at their own expense to install suitable toilet facilities and connect them directly to the sewer — within 180 days of official notice to do so. The same section makes it unlawful, except as the division provides, to construct or maintain a privy, privy vault, septic tank or cesspool.

For a buyer that is a question to settle before closing rather than after: is this property on the public sewer, is it on a septic system, and if it is on a septic system, is there a sewer within 200 feet? A yes to the last one means an obligation that can arrive on a 180-day clock, at the owner’s expense.

What we do not do

We do not evaluate septic systems — that is a separate discipline with its own credentials, and the county health department is where it belongs. What we do cover on the water side is the building and the ground immediately around it: accessible grading and how it falls away from the foundation, gutters and downspouts and where they discharge, foundation conditions, the basement or crawlspace, and any sump equipment and where it sends what it pumps.

The Township’s utility department handles water and sewer billing and publishes its rate changes; it is also the place to confirm what serves a given address. One jurisdiction note while you are asking: Michigan Center is a community within Leoni Township rather than a separate municipality, so a Michigan Center address is a Leoni Township address and these are the rules that apply to it.

Older housing

A fifth of the township predates 1940

Of about 5,884 housing units here, 1,030 were built before 1940 and another 533 in the 1940s. The 1950s added 942 and the 1970s 793. Only 33 units have been built since 2010. Around 88% is single-family detached.

A township whose housing is largely pre-war and mid-century asks specific things of an inspection. Prewar houses were built before wiring, plumbing and heating standardized, which means the systems in them have almost always been replaced in stages by different people over different decades. The panel and the branch circuits often disagree. Original supply plumbing has passed the end of any normal service life. Foundations are frequently stone or unreinforced masonry, with the drainage arrangements of their day.

None of that makes an old house a bad house — plenty of them have outlasted things built fifty years later. But it does mean the interesting questions are about the junctions: where new work meets old, where an addition meets the original structure, where a finished basement covers what used to be visible, and whether the building has been maintained as a whole or patched a piece at a time.

On houses of this age, radon testing is worth considering as an add-on to the same visit, and where there is any history of water in a basement, mold inspection and testing can be added too. Read what clients say about how the reports read.

The buried line

Examination and test, which is what a camera is for

The Township’s ordinance sets the standard: an old building sewer may serve a new building only when it is found, on examination and test, to meet the requirements. The same logic applies to a house changing hands.

On a prewar house that pipe has been in the ground eighty years or more; on a 1950s house, seventy; on a 1970s house, fifty, with the landscaping planted alongside it long since mature. Any of those is more than 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. The ordinance names the materials that have been permitted here over the years — clay, cast iron, concrete, asbestos cement, plastic — but which one runs under a particular house is not something a build year answers.

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 rather than booked separately, and on housing this old it is one of the more useful things you can put on the list.

Alongside it, commercial building inspections follow the CCPIA standard for offices, retail, multifamily and warehouse property. Get in touch to talk through what a particular property needs.

  • 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).

Questions

Leoni Township home inspector questions

  • What does the Township’s lead notice actually say?

    That sampling showed elevated lead in drinking water in some homes. The Township sampled ten homes; the lead 90th percentile came back at 19 parts per billion against an Action Level of 12 ppb, with two sampled sites over the Action Level. The notice is explicit that the Action Level measures corrosion control effectiveness and is not a health-based standard, while also saying the goal for lead in drinking water is zero. Sampling continues every six months at twenty sites, so ask the Township where things currently stand rather than relying on any single published round.

  • Do you test water for lead?

    No. Water testing is a separate discipline with its own certified laboratories, and the Township points residents to the state list of them. Nothing in a building inspection substitutes for a water test. What we can do is report what the visible supply piping appears to be where it is accessible — including where the service enters the building — which is a useful starting point for the question the Township asks residents to answer.

  • How do I find out what my service line is made of?

    The Township asks residents to contact it, or a licensed plumber, to determine whether the line connecting the home to the water main is lead, galvanized or another material. That is the authoritative route. An inspection can tell you what the piping looks like where it is visible inside the building, which often narrows the question but does not settle what is buried beyond the wall.

  • Does the age of the house matter for lead?

    State guidance suggests it can. The Township’s notice reproduces MDHHS advice to use a certified lead-reducing filter where a home has, or may have, lead or galvanized plumbing, a lead service line, copper plumbing with lead solder from before 1988, or faucets and fittings sold before 2014. About 74% of the housing here was built before 1990, and 1,030 units predate 1940 — so for most properties in the township those markers are worth checking rather than dismissing.

  • Can an existing sewer line be reused for a new building here?

    Only after it is checked. The Township’s ordinance allows old building sewers, or portions of them, to be used in connection with new buildings only when they are found on examination and test by the inspector to meet all requirements. That is a municipality declining to take a buried pipe on trust, and the same reasoning applies when a house changes hands.

  • The property is on a septic system. Will I have to connect to the sewer?

    Possibly, and on a short clock. Where a public sewer runs in an abutting street and passes not more than 200 feet at the nearest point from the structure, the owner is required at their own expense to connect within 180 days of official notice. The ordinance also makes it unlawful, except as it provides, to construct or maintain a privy, privy vault, septic tank or cesspool. Establish what the property is on, and how close the nearest sewer runs.

  • How old are homes in Leoni Township?

    Old, and very little is new. Of about 5,884 housing units, 1,030 were built before 1940 and 533 in the 1940s, with 942 from the 1950s and 793 from the 1970s. Only 33 units have been built since 2010, and around 88% is single-family detached. On housing of that age the systems have almost always been replaced in stages by different people over different decades, which is why the junctions between old work and new are where an inspection spends its time.

  • Is Michigan Center part of Leoni Township?

    Yes. Michigan Center is a community within Leoni Township rather than a separate municipality, so a Michigan Center address is a Leoni Township address and the Township’s ordinances and utility arrangements are the ones that apply. Worth confirming with the Township if you are relying on it for anything that matters.
