Plumbing Inspection in Columbia, MD
In Columbia, 20% 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 Columbia, 20% 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 Columbia moved in
At an ordinary rate of turnover, the housing here divides fairly evenly between homes inspected in the last few years and homes that have not been looked at since the previous sale, whenever that was.
| Owner households in Columbia | Share of all owners |
|---|---|
| Moved in 2021 or later | 5% |
| Moved in 2018–2020 | 15% |
| Moved in 2010–2017 | 25% |
| Moved in before 2010 | 55% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 39,859 occupied housing units, of which 25,693 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
Gas leak testing is not part of a home inspection. The fuel shut-off gets located and described; the line itself is not tested, and no part of the report should be read as saying it was.

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.
Worth ten minutes before you read your own report: everything the two standards require, in the order an inspector does it.
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.
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.
