Full Breakdown
There is no dedicated tiny-home ordinance in Spartanburg County. A tiny house on wheels is treated under Section 3.03-2 as a recreational vehicle or travel trailer, which cannot be used or permitted for permanent residential use because it is not built to HUD Standards or the International Residential Code. Such a vehicle may be set up for up to 90 days within a twelve-month period solely to live on-site while building a residence. A foundation-built tiny house that meets the IRC is regulated as a single-family dwelling and must satisfy ULMO Table 3 setbacks and building code. Municipalities set their own rules, so verify your parcel's governing ordinance.
