What Missouri Requires When a Home Is Sold
Missouri law doesn't require a septic inspection before a sale. DHSS says so directly. But if a lender, buyer, seller or agent requests an inspection or evaluation as part of a real-estate transaction, state rule 19 CSR 20-3.070 says it must be done by an individual who meets the Missouri Department of Health and Senior Services requirements for that purpose. In your request, say it's for a sale.
DHSS also notes that local public health agencies mostly no longer inspect existing systems for real-estate transfers. That work is done by these private inspectors and evaluators who meet DHSS requirements.
Don't Confuse It With the County's Existing-System Evaluation
Boone County Resource Management charges a fee for an "existing evaluation" when someone adds bedrooms or bathrooms to a home on septic. That review is tied to remodeling and additions. It isn't a real-estate inspection. For a sale, you need a private inspector or evaluator who meets Missouri DHSS requirements under 19 CSR 20-3.070.
Inspection vs. Evaluation
- Inspection: a thorough assessment of all components, plus a hydraulic test of whether the soil treatment area can take normal flows.
- Evaluation: covers how the tank is working, the observable condition of the soil treatment area, and signs of past or present failure. No hydraulic test.
Reports go to whoever requested them, with copies to DHSS and the local onsite agency. Findings don't automatically mean a violation, and state rules don't require repairs to finish a sale. Buyer and seller decide.
Lagoon Properties
Many rural Boone County homes use lagoons. A lagoon assessment looks at different things than a lateral field does: whether the banks are intact and mowed, whether trees shade the water, whether there's vegetation in the basin, whether the fence and gate are in good shape, and whether the tank ahead of it (if any) is working. Boone County's guide covers these maintenance points in detail, and they're useful for any buyer to walk through.
Clay Soils and What an Inspector Looks For
With heavy clay and perched water tables common in the county, inspectors pay close attention to wet spots, ponding over laterals, and whether a curtain drain is working. A hydraulic test (inspection, not evaluation) is the way to see how the field handles water.
Typical Inspection Cost
NeedSeptic's 2026 Missouri cost page lists septic inspections at about $150–$375. Hydraulic-test inspections and lagoon properties can vary. This is a typical published range, not a quote.
