How much will it cost to build a prefab in Tennessee?
Many owners budget about $175–$250 per sq ft for prefab construction in Tennessee (home-only), with totals varying by finishes, site work, and location. Metro areas like Nashville, Memphis, and Knoxville can add permitting, utility, and labor costs; rural or mountain areas may require added expenses for septic, foundations, or grading on sloped terrain.

Zoning & Permits
Tennessee requires residential building permits at the state and local level. Most jurisdictions have adopted the 2018 International Residential Code with state amendments. Local governments may adopt more current codes—Nashville and some cities now use 2024 editions. Always check with your local building department for site-specific requirements.
Off-Grid & Rural Builds
For rural builds, septic system permits are issued through the Tennessee Department of Environment and Conservation (TDEC) or your local county health department. Applications can be submitted online at tdec.tn.gov/septic. Mountain properties may require additional site work for sloped terrain.
Energy Code & Efficiency
Tennessee enforces the 2018 International Energy Conservation Code (IECC) with state amendments for residential construction. Requirements address insulation, HVAC efficiency, air sealing, and building envelope standards. Enforcement is handled at the local level.
Local Zoning Tools
Zoning and land use in Tennessee vary by municipality and county. The Tennessee Municipal Technical Advisory Service (MTAS) provides comprehensive planning and zoning resources. Contact your city or county planning commission for site-specific zoning rules.
Tip
If you're unsure about your parcel's status—whether it requires TDEC septic approval, falls under specific zoning restrictions, or needs additional site work—contact your local building department or county health department directly. In Tennessee, counties like Davidson, Shelby, Knox, and rural counties across the state all enforce different local rules. The resources above are a great place to start.
