Plumbing Inspection in Westchester, IL
In Westchester, just 16% of owner-occupied homes have changed hands since 2018. A low rate has a consequence people miss: an inspection is the one moment a house gets examined, and most of these have not had one recently.
The one-paragraph answer
Homes in Westchester rarely change hands — only 16% of owner households moved in during 2018 or later — so an inspection there is usually of a house somebody has lived in for years. The buried sewer lateral is still outside both published standards of practice.

When Westchester moved in
Low turnover means the last inspection on most of these houses is old, and the systems in them have had years to change since. Nothing about a settled town makes plumbing age more slowly.
| Owner households in Westchester | Share of all owners |
|---|---|
| Moved in 2021 or later | 4% |
| Moved in 2018–2020 | 12% |
| Moved in 2010–2017 | 27% |
| Moved in before 2010 | 57% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 7,084 occupied housing units, of which 6,473 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
The water heater is covered in some detail by both standards — and InterNACHI is equally explicit that nobody is required to measure its capacity, temperature or adequacy, or to test the relief valve. It is looked at, not operated.

What it is required to cover
The covered list is shorter than the excluded one and it is not thin. Every fixture run, every toilet flushed, the drain-waste-vent system described, the water heater and its venting examined, the shut-offs located. That is a real morning of work and it is worth knowing it happened.
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
Two categories are worth chasing before you exchange: water somewhere it should not be, and anything the report could not see the end of. Both are open-ended, and open-ended is what moves a price.
The published standards settle most arguments: excluded, covered, and the separate instruction for everything past the building.
