Plumbing Inspection in Rock City, IL
In Rock City, just 8% 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
Only 8% of owners in Rock City arrived in 2018 or later, which makes this settled ground. Long tenure does not change the scope: a standard inspection covers what can be seen and operated, and the drain line beyond the house is excluded from it.

When Rock City 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 Rock City | Share of all owners |
|---|---|
| Moved in 2021 or later | 2% |
| Moved in 2018–2020 | 6% |
| Moved in 2010–2017 | 12% |
| Moved in before 2010 | 80% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 509 occupied housing units, of which 456 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
Wells, pumps, pressure tanks, storage tanks and filters are excluded by both standards. On a property with its own supply, the equipment feeding the whole house sits outside the inspection carried out on it.

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.
Worth ten minutes before you read your own report: everything the two standards require, in the order an inspector does it.
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.
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.
