Plumbing Inspection in Warrenville, IL
In Warrenville, 22% 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
22% of owners in Warrenville 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 Warrenville 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 Warrenville | Share of all owners |
|---|---|
| Moved in 2021 or later | 6% |
| Moved in 2018–2020 | 16% |
| Moved in 2010–2017 | 27% |
| Moved in before 2010 | 51% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 5,675 occupied housing units, of which 4,304 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
Both standards state that an inspection is not technically exhaustive and covers readily accessible, visually observable systems. That sentence is not a disclaimer at the end of the report. It is the definition of what was bought.

What it is required to cover
Sump pumps are in scope on both standards — InterNACHI for drainage pumps with an accessible float, ASHI for sewage ejectors and sump pumps. Accessible is the whole qualifier. A float nobody can reach is not a float anybody tested.
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
Ask a contractor what would have to be opened up to answer the question, rather than asking for a number. A quote given without that step is a guess with a figure attached to it.
Both standards are public. Start with the exclusions, then the obligations, and read the sewer scope separately — it is ordered on its own for a reason.
