Plumbing Inspection in Redmond, WA
Redmond turns over at about the national middle: 19% 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
In Redmond, 19% of owner-occupied homes have changed hands since 2018. Whichever side of a sale you are on, the exclusions decide what you know: a standard inspection stops at the visible plumbing and leaves the sewer lateral to a camera survey.

When Redmond moved in
At an ordinary rate of turnover, the housing here divides fairly evenly between homes inspected in the last few years and homes that have not been looked at since the previous sale, whenever that was.
| Owner households in Redmond | Share of all owners |
|---|---|
| Moved in 2021 or later | 5% |
| Moved in 2018–2020 | 14% |
| Moved in 2010–2017 | 38% |
| Moved in before 2010 | 43% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 41,474 occupied housing units, of which 22,753 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
Visual means visual. Pipe inside a wall, under a slab or below grade is not observed, and neither standard asks anyone to open a sealed access panel to reach it. InterNACHI names polybutylene piping in its exclusions outright.

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.
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
Ask a contractor what would have to be opened up to answer the question, rather than asking for a number. A quote given without that step is a guess with a figure attached to it.
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.
