Plumbing Inspection in National Park, NJ
In National Park, 17% 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
17% of owners in National Park 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 National Park moved in
An average rate hides two different populations: recent buyers with a report, and long-standing owners without one. The advice for the two is not the same.
| Owner households in National Park | Share of all owners |
|---|---|
| Moved in 2021 or later | 3% |
| Moved in 2018–2020 | 14% |
| Moved in 2010–2017 | 18% |
| Moved in before 2010 | 65% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 1,083 occupied housing units, of which 910 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
ASHI asks for the predominant material of the water service, distribution and drain-waste-vent pipes to be described. Predominant is an honest word for a house that has been altered more than once, and it is not a complete answer about any single run.

What it is required to cover
Both standards cover the interior drain, waste and vent system, and ASHI asks for the predominant material of the service, distribution and DWV pipes to be described. A report naming one material is describing the majority of the house, not every run in it.
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
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.
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.
