Plumbing Inspection in Baltimore, MD
In Baltimore, 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 Baltimore 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 Baltimore 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 Baltimore | Share of all owners |
|---|---|
| Moved in 2021 or later | 4% |
| Moved in 2018–2020 | 13% |
| Moved in 2010–2017 | 25% |
| Moved in before 2010 | 58% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 80,213 occupied housing units, of which 46,532 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
InterNACHI requires the location of the main water shut-off and the main fuel shut-off to be described, and whether the supply is public or private. Those are the three lines worth copying out of the report on the day you get it, because nobody looks them up until they are standing in water.
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
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.
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.
