Plumbing Inspection in Altadena, CA
In Altadena, just 12% 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 12% of owners in Altadena 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 Altadena moved in
Where houses stay put, an inspection is a rare event, and the report on file — if there is one — describes a building that has since had a decade or more of ordinary use.
| Owner households in Altadena | Share of all owners |
|---|---|
| Moved in 2021 or later | 4% |
| Moved in 2018–2020 | 8% |
| Moved in 2010–2017 | 24% |
| Moved in before 2010 | 64% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 12,724 occupied housing units, of which 10,248 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
Wells, pumps, pressure tanks, storage tanks and filters are excluded by both standards. On a property with its own supply, the equipment feeding the whole house sits outside the inspection carried out on it.

What it is required to cover
InterNACHI requires the location of the main water shut-off and the main fuel shut-off to be described, and whether the supply is public or private. Those are the three lines worth copying out of the report on the day you get it, because nobody looks them up until they are standing in water.
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
Where a report says a condition was observed but its extent could not be established, that is the sentence to act on. It means the boundary of the inspection was reached, not that the problem is small.
Everything above comes from documents you can read yourself: the exclusions, the requirements, and why a camera down the lateral is never part of it.
