Does Christian County, Missouri require a septic inspection to sell a home?
No. Christian County has run a county-wide on-site sewage ordinance since 1992, updated it with Wastewater Standards in 2015, and certifies its own installers on top of the state. Neither the standards nor the Health Department's pages require an inspection when you sell. What usually drives a septic and well inspection here is your buyer's mortgage.

Who and what this applies to
- This applies if your home in Christian County is on a private septic system and/or private well. Parts of the county sit on Ozark karst, where sinkhole and stream setbacks matter for any replacement.
- The trigger is your buyer's loan and inspection contingency: FHA, VA, USDA.
- The county certifies installers locally, in addition to the state registration — so a repair or replacement contractor needs the Christian County certification, not only the DHSS one.
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 Christian County–certified installer and pull the county permit timeline. See your options if it fails.

- Does karst terrain change anything for a Christian County septic system?
- It can. Parts of the county sit on Ozark karst, where sinkhole and stream setbacks affect where a replacement system can go, and may push a repair toward an engineered or alternative system.
- Has Christian County always regulated septic systems this way?
- The county has run a county-wide on-site sewage ordinance since 1992, updated by the 2015 Wastewater Standards. Neither version ties an inspection to a property sale.
