Plumbing Inspection in Rialto, CA
In Rialto, just 13% 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 13% of owners in Rialto 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 Rialto 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 Rialto | Share of all owners |
|---|---|
| Moved in 2021 or later | 3% |
| Moved in 2018–2020 | 10% |
| Moved in 2010–2017 | 29% |
| Moved in before 2010 | 58% |

Universe: 27,316 occupied housing units, of which 17,843 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
ASHI asks for the predominant material of the water service, distribution and drain-waste-vent pipes to be described. Predominant is an honest word for a house that has been altered more than once, and it is not a complete answer about any single run.

What it is required to cover
Knowing what is required is what lets you read the report properly. A finding against something the standard covers is a finding; silence about something it excludes is not reassurance. Most people read the document without that distinction and it is the difference between two very different pieces of paper.
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
Write down where the main water shut-off and the main fuel shut-off are. InterNACHI requires both locations to be described, and they are the two most useful lines in the document.
Before you accept a report, read what it did not have to cover against what it did. Then decide whether the drains outside need their own visit.
