Plumbing Inspection in Allen, TX
Allen turns over at about the national middle: 27% 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 Allen sits near the middle, with 27% 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 Allen 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 Allen | Share of all owners |
|---|---|
| Moved in 2021 or later | 7% |
| Moved in 2018–2020 | 20% |
| Moved in 2010–2017 | 33% |
| 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: 40,668 occupied housing units, of which 29,387 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.
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
Read the exclusions in your own report before the findings. The findings say what was looked at; the exclusions say what you still do not know, and only one of those two lists gets attention.
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.
