Plumbing Inspection in Seneca, MO
Seneca turns over at about the national middle: 21% of its owner households arrived in 2018 or later. Common enough that most people know somebody who has had a report, rare enough that few have read the exclusions in one.
The one-paragraph answer
21% of owners in Seneca 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 Seneca moved in
Enough houses change hands here for inspections to be routine, which tends to make people incurious about them. The scope is where the surprises are, and it is published rather than hidden.
| Owner households in Seneca | Share of all owners |
|---|---|
| Moved in 2021 or later | 5% |
| Moved in 2018–2020 | 16% |
| Moved in 2010–2017 | 25% |
| Moved in before 2010 | 54% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 1,814 occupied housing units, of which 1,468 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.
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
Write down where the main water shut-off and the main fuel shut-off are. InterNACHI requires both locations to be described, and they are the two most useful lines in the document.
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.

Checking a plumber in Missouri
Checking a credential in Missouri
Missouri has no state plumbing board. Section 341.010 of the Revised Statutes requires a certificate for plumbers working in cities or towns of fifteen thousand or more inhabitants, and the chapter elsewhere recognizes licenses issued by any county or city operating under plumbing rules, so the office that issued one is a local office. Start here. Ask the contractor which municipality licenses them and confirm it with that office before work begins.
