Plumbing Inspection in San Bruno, CA
San Bruno rarely changes hands — 14% 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
San Bruno is settled, with 14% of owner households having moved in since 2018. The plumbing most likely to matter in a house held that long is the part no standard inspection covers, which is the buried sewer lateral.

When San Bruno 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 San Bruno | Share of all owners |
|---|---|
| Moved in 2021 or later | 4% |
| Moved in 2018–2020 | 10% |
| Moved in 2010–2017 | 19% |
| Moved in before 2010 | 66% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 15,463 occupied housing units, of which 9,556 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
Gas leak testing is not part of a home inspection. The fuel shut-off gets located and described; the line itself is not tested, and no part of the report should be read as saying it was.

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.
What is actually covered — because silence in a report means one thing about a covered system and something completely different about an excluded one.
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.
