Spalding County, GA Accessory Structures: Tiny Homes (2026)

Spalding County's Article 2 zoning definitions place tiny house among the county's Architectural Definitions in Section 209, item 30, defining it simply as a principal dwelling, with a permanent foundation, with four hundred heated square feet or less. That single sentence is the entirety of the county's tiny-house-specific text; the ordinance does not carry a separate tiny-house overlay district, a minimum lot size unique to tiny houses, or a list of zoning districts where the use is permitted or prohibited by name. Because the definition classifies a tiny house as a principal dwelling rather than an accessory structure, a tiny house built on a lot follows the same district-by-district standards, such as minimum heated floor area, setbacks, and lot size, that apply to any other single-family detached dwelling in that zoning district, unless the district's own article sets a different minimum size that a 400-square-foot home could fail to meet.

A prospective tiny-house owner in unincorporated Spalding County should confirm the minimum dwelling size and lot requirements for the specific zoning district, listed under the district articles of Appendix IV, with the Spalding County Community Development Department before building or placing a permanent-foundation tiny house, since the 400-square-foot definition on its own does not guarantee the use is allowed on every residentially zoned parcel.
