Plumbing Inspection in Carnation, WA
Carnation turns over at about the national middle: 26% of its owner households arrived in 2018 or later. Common enough that most people know somebody who has had a report, rare enough that few have read the exclusions in one.
The one-paragraph answer
Turnover in Carnation sits near the middle, with 26% 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 Carnation moved in
A middling turnover figure is the least informative kind, which is its own useful fact: it means you cannot infer much about any particular house from the town, and the report on the one in front of you is the only evidence that counts.
| Owner households in Carnation | Share of all owners |
|---|---|
| Moved in 2021 or later | 8% |
| Moved in 2018–2020 | 18% |
| Moved in 2010–2017 | 24% |
| Moved in before 2010 | 51% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 2,789 occupied housing units, of which 2,525 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
Both standards exclude septic and other sewage disposal or wastewater treatment systems. The inspector confirms that the fixtures drain; the run leaving the building is not part of the job, and it is the most expensive thing on a property to be wrong about.

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.
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
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.
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.
