Quick answer: new systems require a final inspection before approval for use, and existing systems are typically inspected as part of a building or remodeling permit process. Requirements can vary by situation — the Oldham County Health Department is the authoritative source for what applies to your specific case.
When an Inspection Is Required
A final inspection is required after any new system installation or major repair, before the system is approved for use. Beyond that, local building code offices generally require a health department inspection of an existing septic system prior to issuing a building or remodeling permit — if you’re planning renovations, it’s worth checking with Oldham County Health Department early, before you’re mid-project.
Buying or Selling a Home?
Kentucky does not have a single statewide mandatory point-of-sale septic inspection law that applies uniformly — requirements can depend on your specific transaction, lender, or county. If you’re buying or selling a home with a septic system in Oldham County, confirm directly with the health department or your real estate professional whether an inspection is needed for your specific situation, rather than assuming either way.

What Inspectors Look For
A typical inspection checks the tank’s structural condition, baffles, sludge/scum levels, and the drainfield for signs of saturation or failure — the same fundamentals covered in our maintenance guide. If you’re noticing any warning signs already, check them against our symptom checker before your inspection.
