Plumbing Inspection in South San Francisco, CA
South San Francisco rarely changes hands — 13% of owner households arrived in 2018 or later. The upside is stability. The other side of it is that nothing has triggered an inspection in most of these houses for years.
The one-paragraph answer
Only 13% of owners in South San Francisco 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 South San Francisco moved in
In a town this settled the report is likelier to matter to a seller than a buyer. Knowing what is there before somebody else looks is the whole of the advantage.
| Owner households in South San Francisco | Share of all owners |
|---|---|
| Moved in 2021 or later | 5% |
| Moved in 2018–2020 | 8% |
| Moved in 2010–2017 | 22% |
| Moved in before 2010 | 65% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 22,033 occupied housing units, of which 13,392 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 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.
