Summary
Unincorporated Shelby County has no separate tiny-home ordinance. A permanent tiny house is regulated by the Unified Development Code as a single-family dwelling or, as a second unit, an accessory dwelling unit under UDC 2.7.2D, and must meet county building and residential codes.
Accessory dwelling units shall only be permitted as accessory to single-family detached dwellings that do not contain multiple dwelling units. No more than one accessory dwelling unit shall be permitted per lot.
Full Breakdown
The Memphis/Shelby County UDC contains no tiny-home-specific category, so a tiny house on unincorporated county land is regulated by its function. A tiny house on a permanent foundation as the only home on a lot is treated as a single-family detached dwelling and must meet the zoning district's minimum lot and setback and the residential building code. A tiny house added as a second unit is an accessory dwelling unit under UDC Sec. 2.7.2D: one per lot, accessory to a single-family detached home, sized by lot area, requiring administrative site plan review. A tiny house on wheels is generally treated as a recreational vehicle, and long-term RV occupancy on a residential lot is not permitted. Cities apply their own rules.
Violations & Fines
Placing a tiny house that is not a permitted dwelling use, adding a second beyond the one-ADU limit, or living long-term in a tiny house on wheels on a residential lot violates the UDC, enforced by Planning and Development.
