Summary
South Fulton's zoning code does not treat a tiny home as its own building type. It only allows one as an accessory guest house, capped at 400 square feet instead of the usual 650 to 1,500 square foot range, built to Georgia's residential code, sited in the rear yard, and meeting the principal building's setback line.
(a) No more than one guest house structure per lot may be used for occupancy by relatives, guest(s) or employees that work on the property without payment for rent. (b) A separate kitchen facility shall be allowed. (c) Heated floor area shall be a minimum of 650 square feet and a maximum of 1500 square feet, with the exception that a guest house may be allowed to be constructed as a 400 square foot maximum Tiny House, as defined in this Ordinance and in accordance with current State Minimum Standard Residential Code(s) with Georgia State Amendments. (d) Principal building setbacks shall apply. (e) The location shall be limited to the rear yard.

Full Breakdown
09 of the South Fulton Zoning Ordinance regulates guest houses, the only category under which a tiny home can legally exist on a residential lot. A property may have no more than one guest house, and it can only house relatives, guests or on-property employees who pay no rent; renting it out as a separate dwelling is not permitted under this section. A standard guest house must have heated floor area between 650 and 1,500 square feet and include its own kitchen. 09(c) carves out the tiny house exception: a guest house can instead be built as small as 400 square feet if it meets the current State Minimum Standard Residential Code with Georgia State Amendments, the standard the state applies to manufactured and site-built dwellings statewide.
That 400-square-foot cap sits well below the ordinary guest house minimum, so a homeowner choosing the tiny house route trades floor area for a lower size floor. Placement is fixed: the structure must sit in the rear yard only, and it must still meet the same setback distances required for the principal house on the lot. 09, and it still needs a building permit through the Department of Community Development and Regulatory Affairs before construction.
Violations & Fines
Building an accessory guest house or tiny house without permits, over 400 square feet without meeting the 650-square-foot minimum, outside the rear yard, or closer to the lot line than the principal setback allows is a zoning violation under City Code § 5-1005. The city serves written notice and a deadline to correct; continuing the violation past that deadline is a misdemeanor prosecuted in South Fulton Municipal Court, with each additional day counted as a separate offense.
