Plumbing Inspection in Monrovia, CA
Monrovia rarely changes hands — 10% 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 10% of owners in Monrovia 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 Monrovia 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 Monrovia | Share of all owners |
|---|---|
| Moved in 2021 or later | 4% |
| Moved in 2018–2020 | 7% |
| Moved in 2010–2017 | 27% |
| Moved in before 2010 | 62% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 15,312 occupied housing units, of which 7,604 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
The covered list is shorter than the excluded one and it is not thin. Every fixture run, every toilet flushed, the drain-waste-vent system described, the water heater and its venting examined, the shut-offs located. That is a real morning of work and it is worth knowing it happened.
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
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.
The published standards settle most arguments: excluded, covered, and the separate instruction for everything past the building.
