Summary
There is no separate tiny-home rule in unincorporated Rutherford County. A permanent tiny dwelling is regulated either as a single-family home or, on a lot with an existing house, as an accessory dwelling unit, and must meet the 300-square-foot minimum and adopted building code.
An ADU must however, provide the minimum area requirement of 300 square feet as required by the building codes currently in effect for Rutherford County for a dwelling unit.
Full Breakdown
The Rutherford County Zoning Ordinance has no dedicated tiny-home category. A permanent tiny house on its own lot is treated as a single-family dwelling and must meet the underlying district standards; a second small dwelling on a lot that already has a house is an accessory dwelling unit under Section 1101 Q. In either case it must provide at least the 300-square-foot minimum dwelling area required by the building codes in effect for Rutherford County and comply with setbacks, septic/utility capacity, and the one-acre ADU minimum where an ADU is involved. A tiny house on wheels is generally treated as a recreational vehicle, not a permanent dwelling. Cities set their own tiny-home rules; confirm with Planning before building.
Violations & Fines
Occupying a tiny structure that does not meet the minimum dwelling area or building code, or an unapproved second unit, is a zoning violation and misdemeanor fined as prescribed by Tennessee statutes, and occupancy can be ordered to cease.
