Plumbing Inspection in Kirkland, WA
Kirkland turns over at about the national middle: 20% 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
20% of owners in Kirkland bought in 2018 or later, an ordinary rate. Ordinary is where the usual mistake happens, which is assuming the inspection covered the plumbing: the buried lateral is excluded by both published standards.

When Kirkland 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 Kirkland | Share of all owners |
|---|---|
| Moved in 2021 or later | 6% |
| Moved in 2018–2020 | 14% |
| Moved in 2010–2017 | 32% |
| Moved in before 2010 | 49% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 38,459 occupied housing units, of which 23,860 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
ASHI asks for the predominant material of the water service, distribution and drain-waste-vent pipes to be described. Predominant is an honest word for a house that has been altered more than once, and it is not a complete answer about any single run.

What it is required to cover
The fixtures are a live test rather than a look. InterNACHI requires the inspector to run the water at every faucet, flush every toilet, and check that every sink, tub and shower drains; ASHI requires functional flow and functional drainage. If a fault shows up in ordinary use, this is the part of the inspection that finds it.
The full list of obligations is published here. Reading it once is what stops a standard note from looking like a finding.
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.
Both standards are public. Start with the exclusions, then the obligations, and read the sewer scope separately — it is ordered on its own for a reason.
