Plumbing Inspection in Sanborn, IA
In Sanborn, 20% 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
20% of owners in Sanborn 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 Sanborn 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 Sanborn | Share of all owners |
|---|---|

| Moved in 2018–2020 | 17% |
| Moved in 2010–2017 | 28% |
| Moved in before 2010 | 52% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 707 occupied housing units, of which 547 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
Neither standard requires an inspector to determine water flow, pressure, quality or potability. A report can be entirely clean on a house whose water arrives at a pressure nobody would live with, because that was never a defect it was looking for.

What it is required to cover
InterNACHI requires the location of the main water shut-off and the main fuel shut-off to be described, and whether the supply is public or private. Those are the three lines worth copying out of the report on the day you get it, because nobody looks them up until they are standing in water.
Worth ten minutes before you read your own report: everything the two standards require, in the order an inspector does it.
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.
The published standards settle most arguments: excluded, covered, and the separate instruction for everything past the building.
