Tennessee — Rural-permissive, but major cities are stricter than the state's reputation (verified 2026-08)
Tiny home on wheelsTiny homes on wheels are generally classified as RVs. This is a meaningful correction from an earlier draft: Tennessee's three largest cities are notably restrictive, not just its rural counties. Nashville does not allow a tiny home as the primary structure on a lot at all — only as a detached ADU behind an existing conventional home, and only in specific zones. Memphis and Knoxville follow a similar pattern. THOWs are generally not permitted for full-time habitation outside licensed RV parks in any of the three.
ADU / accessory unitThe state uses the IRC as a baseline, but individual counties choose whether to enforce a building code at all — many rural counties don't. A number of counties (Bradley, Anderson, Putnam, and others) have specifically adopted Appendix Q, creating a defined path for foundation-built tiny homes under 400 sq ft. Rutherford County has gone further, adopting a dedicated tiny-house ordinance under 2024 IRC Appendix BB with its own ceiling-height and egress rules.
Minimum square footageNone at state level; individual counties vary, some with no minimum
Foundation requirementRural counties without local code enforcement are the most flexible; several tiny-home builder clusters exist specifically because of this
Local notesDon't assume 'Tennessee is tiny-home friendly' extends to Nashville, Memphis, or Knoxville proper — check the specific city ordinance, since the three largest metros are the exception to the state's rural-permissive reputation, not an extension of it.
!Zoning is set by your specific city or county, not the state as a whole. Use this as a starting point, then confirm with the local building or planning department before you buy land or start a build. Not legal advice.
