Plumbing Inspection in Oak Lawn, IL
In Oak Lawn, 18% 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
18% of owners in Oak Lawn 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 Oak Lawn moved in
An average rate hides two different populations: recent buyers with a report, and long-standing owners without one. The advice for the two is not the same.
| Owner households in Oak Lawn | Share of all owners |
|---|---|
| Moved in 2021 or later | 5% |
| Moved in 2018–2020 | 12% |
| Moved in 2010–2017 | 23% |
| Moved in before 2010 | 59% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 21,745 occupied housing units, of which 17,940 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
Visual means visual. Pipe inside a wall, under a slab or below grade is not observed, and neither standard asks anyone to open a sealed access panel to reach it. InterNACHI names polybutylene piping in its exclusions outright.

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 covered list in full. Most people read the exclusions and stop; the two only mean anything against each other.
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.
Everything above comes from documents you can read yourself: the exclusions, the requirements, and why a camera down the lateral is never part of it.
