How to Find the Septic Records for a Property in Maury or Williamson County
Two counties, two completely separate filing systems, and the link most pages still send you to has been switched off.
People go looking for septic records for one of four reasons: they are buying a house and the inspector asked, they are selling and the buyer asked, they want to add a bedroom and need to know what the system was sized for, or the tank needs pumping and nobody knows where it is buried.
All four need the same paperwork. Where that paperwork lives depends entirely on which county the parcel sits in, and the two counties on this corridor do it completely differently.
Maury County: the records are held by the state
Maury is not one of Tennessee's nine contract counties, so septic here is administered by TDEC and the files sit in the state system. Search them yourself:
TDEC Document Viewer — Search for Septic Tank Permits
- Worth knowing
- A great many pages, including some that rank well for
this, still link
tdec.tn.gov/filenetsearch. That address now returns 410 Gone. We checked it on the date at the top of this page. If a guide sent you there and it failed, that is why, and the Document Viewer link above is the current one.
If the Document Viewer does not turn up your property, TDEC also accepts file requests by email at [email protected]. Older systems, and systems permitted before records were digitised, are the usual reason a search comes back empty. An empty search result is not proof that no system was permitted.
Williamson County: the records are held by the county
Williamson has run its own septic program since January 1993, which means the state system does not hold its files. Requests go to the Williamson County Department of Sewage Disposal Management through the county form:
Williamson County — Septic Records Request
The form asks for your name, email, phone and the property address, and then makes you pick which record you want. There are four:
| Record | What it is, and when you want it |
|---|---|
| Permit | The original approval to install. Shows the system was authorised and what it was approved for. |
| Repair Permit | Issued when an existing system was repaired or altered. Its absence is not proof no repair happened. |
| Soil Map | The soil consultant's map of the lot. This is the document that shows where the field is, and it is usually what you actually want if you are trying to locate a system. |
| COC | Certificate of Completion, issued after the final inspection passes. The permit says a system was allowed; the COC says it was finished and approved. Buyers and closing attorneys ask for this one. |
One thing the county form points out and people miss: if what you need is the plat or location map, that is not a septic record and Sewage Disposal Management does not hold it. That comes from the Register of Deeds, on 615-790-5706.
Spring Hill is the trap
Spring Hill sits across the Maury/Williamson county line. A Spring Hill mailing address tells you nothing about which office holds the file, because the split follows the parcel, not the post office. Establish which county the parcel is actually in before you file a request, or you will wait out a turnaround only to be told the file is in the other building. The same applies to permitting a new system there.
What we do not know
Neither authority publishes a copy fee schedule for records online, so we are not going to print one. Ask what a copy costs when you make the request. We also cannot tell you how far back either system's digitised records reach; if your house predates the 1990s, expect to fall back to an email request rather than the self-service search.
Once you have the records
If the file shows a repair you did not know about, or no COC where you expected one, the next step is usually an inspection by someone licensed to work on the system. Every operator in our directory is checked against the state permit roster — you can see the permit number and the date we checked it on each listing.
If this is for a sale, read what Tennessee actually requires at closing first. The short version is that the state requires disclosure, not inspection, and buyers routinely assume otherwise.
Common questions
- Where do I look up septic records for a property in Maury County?
- Maury County records are held by the state. Use TDEC's Document Viewer at tdec.tn.gov/document-viewer/search/stp. The older tdec.tn.gov/filenetsearch address that many sites still link now returns 410 Gone.
- Where do I look up septic records in Williamson County?
- Williamson runs its own septic program, so its records are not in the state system. Use the county's Septic Records Request form under Sewage Disposal Management. It asks for the property address and which record you want: Permit, Repair Permit, Soil Map, or COC.
- What is a septic COC?
- A Certificate of Completion, issued when an installed system passes its final inspection. It is the document that shows a system was actually approved rather than merely permitted, which is why it is the one buyers and closing attorneys ask for.
- Which county holds the records for a Spring Hill property?
- Whichever county the parcel is physically in. Spring Hill straddles the Maury/Williamson line, so a mailing address does not settle it. Check the parcel, then use that county's route.
- Are septic records public in Tennessee?
- Yes. Permit files are public records, and both routes above are open to anyone, not just the owner. Neither authority publishes a copy fee schedule online, so ask when you request.
