Plumbing Inspection in Oak Brook, IL
20% of owner-occupied homes in Oak Brook have changed hands since 2018. That is an ordinary rate, which makes the ordinary mistake more likely: assuming the inspection covered the plumbing.
The one-paragraph answer
Turnover in Oak Brook sits near the middle, with 20% 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 Oak Brook moved in
Enough houses change hands here for inspections to be routine, which tends to make people incurious about them. The scope is where the surprises are, and it is published rather than hidden.
| Owner households in Oak Brook | Share of all owners |
|---|---|
| Moved in 2021 or later | 6% |
| Moved in 2018–2020 | 14% |
| Moved in 2010–2017 | 31% |
| Moved in before 2010 | 49% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 4,203 occupied housing units, of which 3,356 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 exclude septic and other sewage disposal or wastewater treatment systems. The inspector confirms that the fixtures drain; the run leaving the building is not part of the job, and it is the most expensive thing on a property to be wrong about.

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.
What is actually covered — because silence in a report means one thing about a covered system and something completely different about an excluded one.
What to do about it
Read the exclusions in your own report before the findings. The findings say what was looked at; the exclusions say what you still do not know, and only one of those two lists gets attention.
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.
