Plumbing Inspection in Issaquah, WA
Roughly 24% of the people who own in Issaquah bought since 2018. A normal rate for a town this size, and normal is where the gaps in a standard inspection do their quiet work.
The one-paragraph answer
In Issaquah, 24% 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 Issaquah moved in
Enough houses change hands here for inspections to be routine, which tends to make people incurious about them. The scope is where the surprises are, and it is published rather than hidden.
| Owner households in Issaquah | Share of all owners |
|---|---|
| Moved in 2021 or later | 7% |
| Moved in 2018–2020 | 17% |
| Moved in 2010–2017 | 36% |
| Moved in before 2010 | 40% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 23,661 occupied housing units, of which 15,642 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
The water heater is covered in some detail by both standards — and InterNACHI is equally explicit that nobody is required to measure its capacity, temperature or adequacy, or to test the relief valve. It is looked at, not operated.

What it is required to cover
Sump pumps are in scope on both standards — InterNACHI for drainage pumps with an accessible float, ASHI for sewage ejectors and sump pumps. Accessible is the whole qualifier. A float nobody can reach is not a float anybody tested.
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
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.
