Plumbing Inspection in Oak Park, IL
22% of owner-occupied homes in Oak Park 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
Turnover in Oak Park sits near the middle, with 22% of owner households arriving in 2018 or later. The figure that actually matters is in the standards of practice: a home inspection covers what is visible and operable, and the buried sewer lateral is not.

When Oak Park 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: 23,267 occupied housing units, of which 14,128 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
Sump pumps are in scope on both standards — InterNACHI for drainage pumps with an accessible float, ASHI for sewage ejectors and sump pumps. Accessible is the whole qualifier. A float nobody can reach is not a float anybody tested.
The covered list in full. Most people read the exclusions and stop; the two only mean anything against each other.
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.
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.
