You don't need a perfect system to sell. You need a permit that matches the house, an honest disclosure, lids a buyer's inspector can open, and a plan if something's wrong.
No. Tennessee has no statewide rule requiring a septic inspection to sell, but buyers usually order one, some loans require one, and agents preparing purchase offers must include notice that a TDEC inspection letter is available. Before listing, pull your TDEC permit, confirm the bedroom count, and disclose any septic problem you know about.
No state rule requires one. But the buyer's side will almost certainly raise it. Tennessee Real Estate Commission Rule 1260-02-.37 requires the agent writing an offer to buy to include a notice that a septic inspection letter is available from TDEC for a fee. So your buyer gets reminded in writing, on the offer itself.
Loans add their own requirements. USDA guaranteed loans require the lender to get a septic evaluation and don't allow observable failure. FHA and VA have property standards for sewage, and many lenders add conditions. If your buyer is using one of those, expect an evaluation before closing.
Buyers usually pay for their own inspection. You still need to give them safe access to the lids and enough time to do it.
| Who | Requirement |
|---|---|
| Tennessee law | No required septic inspection at sale |
| Buyer's agent (TREC Rule 1260-02-.37) | Must note in the offer that a TDEC inspection letter is available |
| USDA lender | Septic evaluation, no observable failure |
| FHA or VA lender | Program sewage standards plus lender conditions |
| Purchase contract | Whatever inspection contingency you accept |

Tennessee's Residential Property Disclosure Act covers known material defects. Section 66-5-202 provides for the disclosure statement, or a disclaimer statement only when the buyer waives disclosure. Section 66-5-203 covers delivering it before the contract is fully signed. The disclosure is your representation, not a warranty, and it doesn't replace the buyer's inspections.
You don't have to hire an inspector just to fill out the form. But if you know about a backup, surfacing sewage, a recurring alarm, an unpermitted repair, or more bedrooms than the permit allows, that goes on the form. Talk to your agent or a Tennessee real estate attorney about the wording.
Section 66-5-205 covers changes. If something happens after you fill out the form, like a backup, a new wet spot, or a failed inspection, you have to disclose it or certify the property is substantially the same at or before closing.
| Legal point | What to do |
|---|---|
| Known material defect | Describe it accurately and attach reports and invoices if your agent advises it |
| No inspection required to complete the form | Don't guess. Say what you know and what you don't |
| Disclosure isn't a warranty | Skip "perfect" or "never had a problem" in the listing |
| Disclaimer needs the buyer's waiver | "As is" in the listing doesn't replace the statutory process |
| Changes before closing | Update or certify at or before closing |
| Some sales are exempt | Foreclosures, court-ordered sales, and some others. Ask your attorney |

Often it's worth it. One Columbia-based provider publishes $250 for a standalone inspection and $825 for pump-out plus inspection (prices verified May 2026). TDEC's fee to inspect an existing system is $200 under Rule 0400-48-01-.21. Either is small next to a buyer asking for $10,000 off because of an unknown.
The trade-off is that anything the inspection finds becomes something you know, and you'll have to disclose it. That's the reason some sellers skip it. But a buyer's inspector will likely find the same problem later, with less time on the clock and more leverage on their side.
| Choice | Upside | Downside |
|---|---|---|
| Inspect before pricing | Time to fix it, get permits, and market a clean system | Whatever it finds, you must disclose |
| Wait for the buyer's inspection | No cost to you up front | Surprises land mid-contract with short deadlines |
| Hand over an older report | Shows history | May not reflect current condition, and buyers may not rely on it |
| Pump without inspecting | Handles due maintenance | Doesn't test the field and erases evidence the buyer's inspector wants |
List the bedroom count on the TDEC permit. If the permit says three and the house has five rooms someone could sleep in, marketing it as a five-bedroom creates a capacity problem the buyer's inspector or appraiser can catch. Calling rooms an office or bonus room doesn't settle the septic question by itself.
Confirm the house is actually on septic. A 2025 Tennessee Real Estate Commission disciplinary record describes a sale where documents said public sewer but the home had septic. Pull the TDEC record and check with the utility before the listing goes live.
Name the system type accurately: gravity, pump, aerobic, low-pressure pipe, mound, or drip. Each has different upkeep, and buyers will price it in.
Cut water use and keep people away from sewage, broken lids, and wet electrical parts. The listing can wait a day.
A bad pump, float, baffle, or lid is a part repair. A failed drain field is a different, bigger job. Ask for the measurements behind any "failed" label.
Field repairs need a TDEC repair permit. TDEC currently charges no fee for the repair permit and $100 for the repair inspection. TDEC's Columbia field office handles Maury County.
Give every contractor the same permit and drawings so the prices actually compare. Ask what's excluded.
Repair before closing, cut the price, offer a credit, or set up an escrow holdback. The buyer's lender has to accept whatever you choose.
Make the disclosure, listing remarks, and repair paperwork match the new facts before closing.
| Factor | Repair before closing | Price cut, credit, or escrow |
|---|---|---|
| Buyer pool | Keeps FHA, VA, and USDA buyers in play | May narrow it to cash or renovation buyers |
| Timing | Weather, permits, and contractor schedules can delay closing | Can close sooner if the lender allows open work |
| Cost control | You pick the bid but own any overrun | Buyers usually ask for more than the bid to cover their risk |
| Buyer confidence | Final TDEC approval and a paid invoice are strong proof | A credit doesn't prove the repair can be permitted |
| Negotiation | Resolved problems stop the back-and-forth | Open problems invite more inspection demands |
Buyers rarely accept the contractor's middle number. They add in permit time, the chance the digging finds more, lawn repair, and resale worries. That's why an undefined $10,000 allowance can cost you more than a scoped, permitted repair with a final approval.
Expect requests for records, lid access, TDEC contact, a second bid, and more time. Decide ahead of time what you'll provide and who can authorize work. A clear file usually protects your price better than insisting it's never backed up.

Yes, but it changes the sale. Disclose it, get the TDEC repair path and real bids, then decide with your agent whether to repair, cut the price, or offer a lender-approved credit or escrow. USDA loans don't allow observable failure, and FHA and VA buyers often hit the same wall.
No. Tennessee's disclaimer route requires the buyer to waive disclosure, and "as is" language doesn't erase a known problem. Disclose what you know through the forms your agent or attorney recommends.
Only if it's due, and ideally as part of an inspection. Pumping right before a buyer's inspection erases the normal liquid level their inspector wants to see and can look like you're hiding something. Keep the receipt either way.
It's risky. Buyers, appraisers, and lenders can compare the listing with the TDEC record. List the permitted count until TDEC approves a modification. Renaming rooms or removing a bed doesn't change the permit.
The TDEC permit and sketch, any repair or modification approvals, inspection and pumping records, repair invoices, warranties, manuals, and the service contract for aerobic or drip systems. Note any record you couldn't find.
Share the inspection report, the TDEC record, what failed, and your target listing date. If a licensed installer who covers your area can quote the repair, we'll pass it along so you have a number before you list. This form isn't legal advice or TDEC approval.
