Plumbing Inspection in Westminster, CO
24% of owner-occupied homes in Westminster have changed hands since 2018. That is an ordinary rate, which makes the ordinary mistake more likely: assuming the inspection covered the plumbing.
The one-paragraph answer
Turnover in Westminster sits near the middle, with 24% of owner households arriving in 2018 or later. The figure that actually matters is in the standards of practice: a home inspection covers what is visible and operable, and the buried sewer lateral is not.

When Westminster moved in
An average rate hides two different populations: recent buyers with a report, and long-standing owners without one. The advice for the two is not the same.
| Owner households in Westminster | Share of all owners |
|---|---|
| Moved in 2021 or later | 6% |
| Moved in 2018–2020 | 18% |
| Moved in 2010–2017 | 30% |
| Moved in before 2010 | 46% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 21,121 occupied housing units, of which 14,179 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
Water conditioning systems are excluded by ASHI outright, along with lawn irrigation, fire suppression and clothes washer connections. None of that is an inspector cutting corners; it is the published boundary of the service.

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.
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
Two categories are worth chasing before you exchange: water somewhere it should not be, and anything the report could not see the end of. Both are open-ended, and open-ended is what moves a price.
The published standards settle most arguments: excluded, covered, and the separate instruction for everything past the building.
