Quick answer: any new septic installation or major repair in Jefferson County requires LMPHW inspection before work is covered. For existing systems, inspections are required as part of building or remodeling permits. Records for any septic system in Louisville Metro must be requested through the Louisville Metro Government’s open records request portal.
When an Inspection Is Required
- New installations and repairs. LMPHW must inspect before any work is covered — this is a mandatory step in the construction permit process, not optional.
- Building or remodeling permits. Local building code offices require LMPHW to inspect an existing septic system before issuing a building or remodeling permit. If you’re planning an addition or renovation, confirm this requirement before starting.
- Plan review. LMPHW’s Plan Review Division must approve plans for residential homes with septic systems before a plumbing or building permit can be issued — including pools on properties with septic systems.
Looking Up Your Septic Records

Unlike some counties that have a direct online lookup, LMPHW requires a formal open records request for any septic system documentation. Plan ahead — this can take several days to fulfilll.

Buying or Selling in Jefferson County
There is no single statewide mandatory point-of-sale septic inspection law in Kentucky that applies uniformly to every transaction. Whether an inspection is required for your specific sale depends on your lender, loan type, or other transaction specifics — confirm directly with LMPHW or your real estate professional rather than assuming either way. See our installation cost guide for what a failing system could mean financially.
