Tennessee does not require a septic inspection to sell a house, does not license septic inspectors, and does not make a passing inspection a condition of closing. It does require sellers to disclose what they know, require agents to tell buyers that a government inspection letter exists, and let Hamilton County sell that letter for $105. If you are listing a home on septic in Chattanooga, Soddy-Daisy or Apison, here is how the pieces fit together.
This is general information, not legal advice. Rules, fees and forms change. Check the current rule or statute, call the agency named, or ask a Tennessee attorney before you rely on anything here.
The disclosure statement asks about your septic system
The Tennessee Residential Property Disclosure Act (TCA 66-5-201 and following) applies to sales of one- to four-unit residential property. Under 66-5-202 the owner furnishes either a disclosure statement "including any material defects known to the owner," or, only where the buyer waives disclosure, an "as is" disclaimer statement. The statute is careful about what the form is not: it "is not a warranty of any kind by a seller and is not a substitute for inspections either by the individual purchasers or by a professional home inspector," and the owner "shall not be required to undertake or provide any independent investigation or inspection of the property."
The form itself is published by Tennessee REALTORS® and is copyrighted, so we quote the statute rather than the form. A Tennessee Court of Appeals opinion quotes the septic question from an earlier version as "Are you (Seller) aware of any defects/malfunctions in [sewer/septic]?" with yes, no and unknown boxes. If you have had backups, a wet drain field or a repair, "unknown" is not an honest answer.
Perc tests and sinkholes must be disclosed separately
A second statute, TCA 66-5-212, adds two septic-adjacent disclosures that go in the contract itself or in a separate signed writing before the contract is entered. Subsection (a): the seller must disclose "the results of any known percolation test or soil absorption rate performed on the property that is determined or accepted by the department of environment and conservation." Subsection (c)(1): the seller must disclose "the presence of a known sinkhole on the property," defined as "a subterranean void created by the dissolution of limestone or dolostone strata resulting from groundwater erosion, causing a surface subsidence of soil, sediment, or rock" that "is indicated through the contour lines on the property's recorded plat map."
Both matter more here than in most of Tennessee. Hamilton County's valley floor sits on Ordovician carbonates and the Knox Group dolomites, and a UTC geologist has said plainly, "You can say this is a region that is prone to sinkhole development." If a perc test was done when the lot was permitted, that result is on file with Hamilton County Groundwater Protection. One caveat: the copy of 66-5-212 we consulted was labeled "effective until 7/1/2024," so check the current text for amendments before relying on it.
New construction: the bedroom count on the permit
For a newly built home, TCA 47-18-104(b)(41) makes it unlawful to market "a newly constructed residence as having more bedrooms than are permitted by the newly constructed residence's subsurface sewage disposal system permit" unless the permitted number is disclosed in writing before the sales agreement; a buyer who was not told can rescind and recover treble damages. Pull the permit and match the listing to it.
What your agent must tell the buyer
Tennessee Real Estate Commission Rule 1260-02-.37, "Septic System Inspection Letters," says: "A licensee preparing an offer to buy shall provide in the offer and make the buyer aware that, for a fee, a septic system inspection letter is available through the Tennessee Department of Environment and Conservation, Division of Ground Water Protection." That is a duty to inform, not a requirement to obtain the letter, and nothing in the rule requires a passing result to close. But most buyers will hear about the letter during the offer, so sellers should know what it is.
The $105 Inspection Letter and the $180 Recertification Letter
Because Hamilton County is a TDEC contract county, the letter the rule refers to is sold locally by the county's Division of Groundwater Protection (1250 Market Street, Suite 3046; (423) 209-7876). The current fee schedule lists an Inspection Letter at $105, a Recertification Letter at $180 and an Existing Septic Tank Approval at $205. The county's request form asks the age of the house and whether it is vacant and for how long. These are government products, not the written report a septic company produces during a septic inspection, and the county does not publish exactly what each letter certifies, so ask Groundwater Protection which one your sale needs before you pay. In Bradley County and other non-contract counties, TDEC's equivalent is an "inspection of existing systems" at $200 under Rule 0400-48-01-.21.
Why the home inspection will not cover it
Buyers often assume the general home inspection includes the septic system. TCA 62-6-302(4)(F) requires every home inspection report to include "a statement that the report does not address subterranean systems or system components, operational or nonoperational, including: (i) Sewage disposal; (ii) Water supply; or (iii) Fuel storage or delivery." Tennessee also has no septic-inspector license. A septic inspection is therefore a separate visit, usually by a permitted pumper or installer, typically $100–$200 visual or $250–$1,175 with a camera (national estimates), often combined with a pump-out so the tank walls and baffles can be seen.
The buyer's view
A buyer has just been told a county letter exists, and their home inspector's report says, by law, that it does not cover sewage disposal. They know a drain field replacement runs $5,000–$12,000 nationally (about $7,000 typical, up to $20,000). They will want three things:
- The permit. It shows the tank size, the bedroom count the system was designed for, and the field layout. It is on file with the county.
- A recent pump-out and written inspection finding. Not a verbal "looks fine." A dated description of sludge depth, baffles, filter, lid condition and the drain field surface.
- The county letter, if the lender or the buyer asks for it. We did not research FHA or VA septic requirements, so do not assume a lender will or will not ask.
Who pays is not set by any Tennessee rule; it is negotiated like any other inspection. Sellers who order the pump-out and inspection before listing control the timing and remove a reason for the buyer to renegotiate later.
A seller's checklist
Pull the permit
Request the septic permit and any perc-test record from Hamilton County Groundwater Protection (or TDEC's file search for Bradley County).
Check the plat for a sinkhole notation
66-5-212 ties the sinkhole disclosure to the recorded plat's contour lines.
Pump and inspect before listing
Ask for the finding in writing and keep the invoice; see septic tank pumping for what the visit involves.
Fix what the inspection found
Repairs beyond pumping need a permitted installer and the county's $40 repair permit; see septic repair.
Decide on the county letter and fill in the disclosure honestly
Call Groundwater Protection to confirm which letter fits your sale; the statute protects buyers, not sellers who answered "unknown" to something they knew.
How this site fits in
Septic Pumping Chattanooga connects Chattanooga-area homeowners with independent local septic pumping, inspection and repair companies for free, no-obligation quotes. We do not inspect anything, we are not a title or real-estate service, and the county letters are bought from the county, not from us or any contractor. For a pre-listing pump-out or septic inspection, request free quotes; we usually reply the same day.
Frequently asked questions
Is a septic inspection required to sell a house in Tennessee?
No. Tennessee has no point-of-sale septic inspection law and no septic-inspector license. TREC Rule 1260-02-.37 only requires the buyer's agent to say that a government inspection letter is available for a fee. Sellers must disclose known defects on the disclosure statement and any known perc test or sinkhole under TCA 66-5-212. Lender requirements were not researched. This is general information, not legal advice.
What is the Hamilton County septic Inspection Letter?
It is a government product sold by Hamilton County's Division of Groundwater Protection, listed at $105 on the current fee schedule, alongside a Recertification Letter at $180 and an Existing Septic Tank Approval at $205. It is the letter TREC Rule 1260-02-.37 tells agents to mention. The county does not publish exactly what each letter certifies, so call (423) 209-7876 to confirm which one your sale needs.
Who pays for the septic inspection when selling a house in Tennessee?
No Tennessee statute or rule assigns the cost; it is negotiated like any other inspection. Sellers who pump and inspect before listing, with the finding in writing, set the timing and often avoid a later renegotiation. A standard septic inspection runs about $100–$200 nationally, more with a camera, and the county letter is a separate government fee paid to Hamilton County, not to the contractor.
