Plumbing Inspection in Naperville, IL
In Naperville, 19% 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
In Naperville, 19% of owner-occupied homes have changed hands since 2018. Whichever side of a sale you are on, the exclusions decide what you know: a standard inspection stops at the visible plumbing and leaves the sewer lateral to a camera survey.

When Naperville moved in
A middling turnover figure is the least informative kind, which is its own useful fact: it means you cannot infer much about any particular house from the town, and the report on the one in front of you is the only evidence that counts.
| Owner households in Naperville | Share of all owners |
|---|---|
| Moved in 2021 or later | 6% |
| Moved in 2018–2020 | 14% |
| Moved in 2010–2017 | 29% |
| Moved in before 2010 | 52% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 61,065 occupied housing units, of which 46,067 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
Fire suppression and sprinkler systems are outside the inspection. In a house that has one, the system most likely to matter in an emergency is the one nobody was asked to look at.

What it is required to cover
InterNACHI requires the location of the main water shut-off and the main fuel shut-off to be described, and whether the supply is public or private. Those are the three lines worth copying out of the report on the day you get it, because nobody looks them up until they are standing in water.
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
If you are selling, establish it before somebody else does. The same finding is worth more to a buyer who discovered it than to one who was told.
The published standards settle most arguments: excluded, covered, and the separate instruction for everything past the building.
