Plumbing Inspection in Thornton, CO
In Thornton, 21% of owner households moved in during 2018 or later — close to the middle of the towns we cover. Enough movement that inspections are routine, not enough that anybody treats them as routine.
The one-paragraph answer
21% of owners in Thornton 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 Thornton 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 Thornton | Share of all owners |
|---|---|
| Moved in 2021 or later | 8% |
| Moved in 2018–2020 | 13% |
| Moved in 2010–2017 | 32% |
| Moved in before 2010 | 46% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 12,237 occupied housing units, of which 9,580 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 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
Write down where the main water shut-off and the main fuel shut-off are. InterNACHI requires both locations to be described, and they are the two most useful lines in the document.
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.
