Summary
Simpsonville's Zoning Ordinance has no dedicated tiny-home category. A tiny house on wheels is treated as a recreational vehicle or travel trailer, which cannot be used as a dwelling or accessory dwelling unit. A tiny house on a foundation must meet all standard single-family district and building-code requirements.
Mobile homes, recreational vehicles, and travel trailers shall not be used as accessory dwelling units.
Full Breakdown
There is no tiny-home ordinance in Simpsonville. A movable tiny house falls under the definitions for recreational vehicles/travel trailers, which the Zoning Ordinance says shall not be used as accessory dwelling units, and accessory dwelling units themselves are limited to upper floors of nonresidential buildings (Sec. 3.3.4). A tiny house built on a permanent foundation is simply a small single-family dwelling and must satisfy the district's minimum standards, setbacks, and the South Carolina Residential Building Code (minimum room sizes, egress, etc.). Placing a tiny house on wheels as a residence in a residential yard is not a permitted accessory use. Confirm any specific plan with the Planning & Codes Department.
Violations & Fines
Occupying a non-conforming tiny house or RV as a dwelling is a zoning violation; the City may require removal and withhold permits. Penalties follow Code section 1-9.
