Plumbing Inspection in Snohomish, WA
Snohomish turns over at about the national middle: 22% 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 Snohomish sits near the middle, with 22% 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 Snohomish 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 Snohomish | Share of all owners |
|---|---|
| Moved in 2021 or later | 6% |
| Moved in 2018–2020 | 16% |
| Moved in 2010–2017 | 31% |
| Moved in before 2010 | 48% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 23,906 occupied housing units, of which 20,296 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
ASHI requires the energy source and vent system of the water heating equipment to be covered, and InterNACHI requires the same ground from the other direction. Where the two standards overlap is the part of the report you can rely on whichever association the inspector belongs to.
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
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 two standards are published in full and worth ten minutes: what is excluded, what is covered, and why the drains outside the house are a separate instruction.
