Plumbing Inspection in San Gabriel, CA
San Gabriel is settled. Only 9% of owner households moved in during 2018 or later, which means most of the plumbing here has not been looked at by anybody in a long time.
The one-paragraph answer
Only 9% of owners in San Gabriel 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 San Gabriel 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 San Gabriel | Share of all owners |
|---|---|
| Moved in 2021 or later | 3% |
| Moved in 2018–2020 | 6% |
| Moved in 2010–2017 | 22% |
| Moved in before 2010 | 70% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 20,086 occupied housing units, of which 10,230 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
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.
The rest of what an inspector must do is set out here. It is shorter than the excluded list and it is the half that tells you what a finding is worth.
What to do about it
Read the exclusions in your own report before the findings. The findings say what was looked at; the exclusions say what you still do not know, and only one of those two lists gets attention.
The published standards settle most arguments: excluded, covered, and the separate instruction for everything past the building.
