Does a Missouri septic inspection include the well?

Yes, when there's a private well on the same property. State rule requires the inspector to also collect a water sample and inspect the visible water-supply construction — one visit, one licensed person, both systems.

Who is allowed to do the inspection?

Only someone currently licensed by Missouri DHSS as an inspector/evaluator — not a repair contractor, not the well driller, and not anyone working under an unlicensed person’s supervision.

How long is a septic inspection report good for?

The state rule itself doesn't set an expiration date. A county ordinance or your buyer's lender may still have their own timing requirement — worth confirming before you assume an older report still counts.

Does the inspector also do the repair if something fails?

They can, but they have to tell you first that you're not obligated to use them — Missouri rule keeps that choice with you.

How long the report stays good

The state rule itself doesn't set an expiration date on an inspection report. That's not the same as "always valid" — a county ordinance or your buyer's lender can still impose their own timing requirement on top of the state rule, so confirm before assuming an older report still counts for your transaction.

Whether Missouri requires one at all

Statewide, no — on its own. Some counties require one by their own ordinance; where a loan is involved, FHA/VA/USDA financing usually does too. See your county's actual requirement rather than assuming either way.
