Plumbing Inspection in Saint Charles, IL
Saint Charles turns over at about the national middle: 23% of its owner households arrived in 2018 or later. Common enough that most people know somebody who has had a report, rare enough that few have read the exclusions in one.
The one-paragraph answer
23% of owners in Saint Charles bought in 2018 or later, an ordinary rate. Ordinary is where the usual mistake happens, which is assuming the inspection covered the plumbing: the buried lateral is excluded by both published standards.

When Saint Charles moved in
With turnover near the middle, roughly one owner in five or six arrived recently. For everyone else the last time the plumbing was examined by a third party was whenever they bought.

Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 21,386 occupied housing units, of which 16,989 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
ASHI asks for the predominant material of the water service, distribution and drain-waste-vent pipes to be described. Predominant is an honest word for a house that has been altered more than once, and it is not a complete answer about any single run.

What it is required to cover
ASHI requires the energy source and vent system of the water heating equipment to be covered, and InterNACHI requires the same ground from the other direction. Where the two standards overlap is the part of the report you can rely on whichever association the inspector belongs to.
The full list of obligations is published here. Reading it once is what stops a standard note from looking like a finding.
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.
The two standards are published in full and worth ten minutes: what is excluded, what is covered, and why the drains outside the house are a separate instruction.
