Building Your Own House in Tennessee: Owner-Builder Guide
By Cody Johnston, PE, MBA · · 3 min read
Yes — Tennessee lets you build your own home without a contractor’s license. But Tennessee’s version comes with the most specific limits of any state we practice in: a one-permit-every-two-years cap, and a $25,000 rule on hired help that catches people constantly. I’m a licensed engineer in Tennessee (PE #130921); here’s the practical version.
The rules, in plain English
Under Tennessee’s homeowner exemption (T.C.A. §62-6-103), you can build a residence for your own individual use — not for sale, lease, or rent — with these teeth:
- One permit every two years. The state allows a homeowner one self-build permit per two-year period. This isn’t a guideline; it’s the rule.
- The $25,000 hired-help rule. Anyone you pay more than $25,000 becomes a “prime contractor” and must hold a Tennessee license. Splitting a contract into phases to duck the threshold is explicitly prohibited.
- Never pull a permit for your contractor. If you hire a licensed prime for part of the work, they pull their own permit. A homeowner pulling permits on a contractor’s behalf can relieve the contractor of liability and insurance obligations — exactly backwards from what protects you.
- You’ll sign a homeowner affidavit at the permit office (Knox County, Farragut, Gallatin, and most jurisdictions have a standard form).
What the permit office will ask for
- A site plan — survey, setbacks, utilities or well/septic.
- Architectural drawings — no architect required for a single-family home in Tennessee.
- Structural drawings — sealed by a PE where your jurisdiction requires it, and effectively required once your design uses trusses, engineered lumber, tall walls, or an open plan outside the prescriptive tables. Tennessee adds regional pushes of its own: East Tennessee walkout basements (tall engineered retaining walls carrying the house) and Middle Tennessee’s shallow limestone, where footing design gets genuinely site-specific.
- MEP — mechanical, electrical, plumbing. Usually already on your house plans, and generally not requiring sealed engineering for a single-family home. Licensed trades pull their own trade permits and own their inspections — confirm each does before cover-up.
- Supporting items — energy compliance, soil or septic documentation where applicable.
Why the engineer matters more for you than for anyone else
With no GC absorbing questions, the correction letter, the unchecked truss package, and the framer’s “what does the engineer want here?” all land on you. The structural engineer on an owner-build is your technical partner: the sealed drawings the county requires plus fast, plain-English answers that keep an owner-run schedule moving. On karst ground in Middle Tennessee, we’re also the ones who design to what the geotech actually finds.
The order of operations that works
- Call your codes office: “I’m an owner-builder — what does your permit set need, and which affidavit do I sign?”
- Get the design drawn.
- Bring in the engineer before the design is final — foundation and framing choices are cheap on paper, expensive in concrete.
- Submit the full set, keep every hired prime licensed and pulling their own permits, and mind the $25,000 line.
