Does Lincoln County, Missouri require a septic inspection to sell a home?
Not that we can find. Lincoln County's On-Site Sewage Disposal System Ordinance requires a permit for any new construction, installation, modification, or repair of a septic system, but nothing in it ties an inspection to a property sale itself. What actually drives a septic and well inspection here is your buyer's mortgage. We're confirming this reading directly with the Lincoln County Health Department.
Read against the Lincoln County On-Site Sewage Disposal System Ordinance and the county Health Department's own application-process guide, 2026-09-15. Confirmation from the county is pending. See what we're confirming.
Who and what this applies to
- This applies if your home in Lincoln County is on a private septic system and/or private well.
- The trigger is your buyer's loan and inspection contingency: FHA, VA, USDA.
- One real local wrinkle: the county denies a construction or repair permit if a public sewer connection within 300 feet of the property is practical, economically feasible, and approved by the public sewer authority — those properties get pushed onto public sewer instead of a new or replacement septic system.
What a seller should do
- Find the records and confirm the system type — the pre-listing checklist.
- Book the septic inspection and the water test early, with a DHSS-licensed inspector and a certified lab.
- If a problem turns up, get a written bid from a Lincoln County-licensed installer and pull the county permit timeline. See your options if it fails.

What we're confirming with the county
- that there is no point-of-sale septic or well inspection requirement;
- the current licensed-installer and soil-evaluator roster (the county’s own list we found is dated 2018);
- the Health Department's repair/replacement permit process and realistic timeline;
- whether a private well water test is expected locally at a sale.

Choosing an inspector
Use a Missouri DHSS-licensed inspector, checked against the suspended list; for a repair, Lincoln County requires its own licensed installer, not just the state DHSS credential. The inspector and the repair contractor stay separate under 19 CSR 20-3.070(10). See choosing a septic inspector and a repair contractor.
