Buying or Selling a Septic Property in Mississippi

We have not verified a statewide law in Mississippi requiring a septic inspection at the time a property transfers. That does not mean no requirement applies where you're buying: county and municipal time-of-transfer ordinances exist in various places around the country outside the states with a statewide law. Check the county page below, and ask the local health department directly — that is the authoritative source for a local ordinance, and this page is not.

What we could verify

No statewide Mississippi law requiring septic inspection at time of transfer. Three states do have a real, verified one — Massachusetts, Iowa, and a waterfront-only law in New Hampshire — for comparison; Mississippi is not one of them, at least not at the state level. A county or municipality in Mississippi could still have its own ordinance we have not audited; the local health department for the specific county is the authoritative source.

Who regulates septic in Mississippi

Finding the record before you close

Wherever you're transacting in Mississippi, the septic permit or as-built (where one exists) is almost always held by the county or district health office, not the state. How to find septic records before closing covers how to pull it; below is the county-by-county index of what we hold for Mississippi.
