Plumbing Inspection in Markham, IL
Markham is settled. Only 14% of owner households moved in during 2018 or later, which means most of the plumbing here has not been looked at by anybody in a long time.
The one-paragraph answer
Only 14% of owners in Markham arrived in 2018 or later, which makes this settled ground. Long tenure does not change the scope: a standard inspection covers what can be seen and operated, and the drain line beyond the house is excluded from it.

When Markham moved in
Low turnover means the last inspection on most of these houses is old, and the systems in them have had years to change since. Nothing about a settled town makes plumbing age more slowly.
| Owner households in Markham | Share of all owners |
|---|---|
| Moved in 2021 or later | 3% |
| Moved in 2018–2020 | 12% |
| Moved in 2010–2017 | 23% |
| Moved in before 2010 | 63% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 3,655 occupied housing units, of which 2,679 are owner-occupied. This counts when the CURRENT occupant moved in, so it measures recent moves as a share of the housing stock — not a rate of sales per year.
What the inspection will not cover
Water conditioning systems are excluded by ASHI outright, along with lawn irrigation, fire suppression and clothes washer connections. None of that is an inspector cutting corners; it is the published boundary of the service.

What it is required to cover
Both standards cover the interior drain, waste and vent system, and ASHI asks for the predominant material of the service, distribution and DWV pipes to be described. A report naming one material is describing the majority of the house, not every run in it.
The rest of what an inspector must do is set out here. It is shorter than the excluded list and it is the half that tells you what a finding is worth.
What to do about it
Two categories are worth chasing before you exchange: water somewhere it should not be, and anything the report could not see the end of. Both are open-ended, and open-ended is what moves a price.
Ten minutes of reading covers it: what nobody was required to look at, what they were, and the drain run that is a separate instruction altogether.
