Bartow County, GA Accessory Structures: ADU Rental Restrictions (2026)

5 allows one accessory dwelling unit per lot in residential zoning districts and A-1 agricultural properties, but only if a single-family principal dwelling already exists on the lot or has a building permit that has passed its rough-in and framing inspection. Subsection B is explicit that the structure shall be owner-occupied or by relatives or guests only, and cannot be used as rental property. The definitions article reinforces the same rule, describing a guest house as usable only by family members or guests without payment or consideration.

Size is also capped: on a lot under one acre, the ADU's heated floor area cannot exceed 50 percent of the principal home's heated area or 1,000 square feet, whichever is smaller; on a lot between one and ten acres, the cap rises to 75 percent of the principal home's heated area or 1,500 square feet, whichever is smaller. The ADU cannot be sold separately from the principal dwelling, must meet all accessory-building setbacks, cannot sit closer to the street than the principal building, cannot exceed the principal building's height, and must comply with the standard building codes referenced in Section 18-31 of the Bartow County Building Code. Recreational vehicles, manufactured homes, tiny homes, storage buildings and shipping containers do not qualify as accessory dwelling units regardless of use. 5(B) as written.
