Plumbing Inspection in Denville, NJ
In Denville, 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
In Denville, 21% of owner-occupied homes have changed hands since 2018. Whichever side of a sale you are on, the exclusions decide what you know: a standard inspection stops at the visible plumbing and leaves the sewer lateral to a camera survey.

When Denville 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: 6,686 occupied housing units, of which 5,737 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
Lawn irrigation is excluded. It is buried, it is seasonal, and it is connected to the same supply as the house — which makes it the one excluded item that can affect something the inspection did cover.

What it is required to cover
The fixtures are a live test rather than a look. InterNACHI requires the inspector to run the water at every faucet, flush every toilet, and check that every sink, tub and shower drains; ASHI requires functional flow and functional drainage. If a fault shows up in ordinary use, this is the part of the inspection that finds it.
What is actually covered — because silence in a report means one thing about a covered system and something completely different about an excluded one.
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.
Ten minutes of reading covers it: what nobody was required to look at, what they were, and the drain run that is a separate instruction altogether.
