Plumbing Inspection in Mendham, NJ
Mendham turns over at about the national middle: 24% 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
24% of owners in Mendham 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 Mendham moved in
With turnover near the middle, roughly one owner in five or six arrived recently. For everyone else the last time the plumbing was examined by a third party was whenever they bought.

Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 3,487 occupied housing units, of which 3,198 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
Both standards state that an inspection is not technically exhaustive and covers readily accessible, visually observable systems. That sentence is not a disclaimer at the end of the report. It is the definition of what was bought.

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
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 published standards settle most arguments: excluded, covered, and the separate instruction for everything past the building.
