Plumbing Inspection in Grayslake, IL
In Grayslake, 24% of owner households moved in during 2018 or later — close to the middle of the towns we cover. Enough movement that inspections are routine, not enough that anybody treats them as routine.
The one-paragraph answer
Turnover in Grayslake sits near the middle, with 24% of owner households arriving in 2018 or later. The figure that actually matters is in the standards of practice: a home inspection covers what is visible and operable, and the buried sewer lateral is not.

When Grayslake 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: 14,244 occupied housing units, of which 11,784 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
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 covered list, and why the distinction between the two lists is the whole of reading a report properly.
What to do about it
Where a report says a condition was observed but its extent could not be established, that is the sentence to act on. It means the boundary of the inspection was reached, not that the problem is small.
The published standards settle most arguments: excluded, covered, and the separate instruction for everything past the building.
