Plumbing Inspection in Northbrook, IL
19% of owner-occupied homes in Northbrook have changed hands since 2018. That is an ordinary rate, which makes the ordinary mistake more likely: assuming the inspection covered the plumbing.
The one-paragraph answer
19% of owners in Northbrook 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 Northbrook 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 Northbrook | Share of all owners |
|---|---|
| Moved in 2021 or later | 6% |
| Moved in 2018–2020 | 13% |
| Moved in 2010–2017 | 29% |
| Moved in before 2010 | 51% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 16,290 occupied housing units, of which 13,312 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
Wells, pumps, pressure tanks, storage tanks and filters are excluded by both standards. On a property with its own supply, the equipment feeding the whole house sits outside the inspection carried out on it.

What it is required to cover
The water heater is covered in more detail than most of the system: InterNACHI takes in the energy source, the venting connections, the temperature and pressure-relief valve, seismic bracing where it applies, and the labeled capacity. What it stops short of is operating any of 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
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.
Everything above comes from documents you can read yourself: the exclusions, the requirements, and why a camera down the lateral is never part of it.
