Plumbing Inspection in Rancho Cucamonga, CA
19% of owner-occupied homes in Rancho Cucamonga 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
In Rancho Cucamonga, 19% of owner-occupied homes have changed hands since 2018. Whichever side of a sale you are on, the exclusions decide what you know: a standard inspection stops at the visible plumbing and leaves the sewer lateral to a camera survey.

When Rancho Cucamonga moved in
With turnover near the middle, roughly one owner in five or six arrived recently. For everyone else the last time the plumbing was examined by a third party was whenever they bought.
| Owner households in Rancho Cucamonga | Share of all owners |
|---|---|
| Moved in 2021 or later | 5% |
| Moved in 2018–2020 | 15% |
| Moved in 2010–2017 | 26% |
| Moved in before 2010 | 55% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 57,983 occupied housing units, of which 36,703 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
Water conditioning systems are excluded by ASHI outright, along with lawn irrigation, fire suppression and clothes washer connections. None of that is an inspector cutting corners; it is the published boundary of the service.

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.
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
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.
Ten minutes of reading covers it: what nobody was required to look at, what they were, and the drain run that is a separate instruction altogether.
