Carroll County, GA Building Setbacks & Zoning: Lot Coverage Limits (2026)

The Office and Institutional (OI) district exists to encourage quiet, compatible office, business, institutional and specified public-purpose development while discouraging encroachment by unrestricted retail or industrial uses. 0) run from minimum lot area of 5,000 square feet where public water and sewer are both available, up to 40,000 square feet where neither is available, through a 100-foot minimum lot width, a 40-foot front setback, 15-foot side and rear yards that widen to 30 and 50 feet against a residential district, and a 35-foot maximum building height.

5 closes that list: the area of the footprint of all buildings and parking shall not exceed 60 percent of the total lot area. No more than 25 percent of a building's total floor area may be devoted to storage under the same section. The zoning chapter as staged for this record sets no comparable lot-coverage percentage for the Agricultural, Residential, Manufactured Home Subdivision, Multi-Family Residential, Commercial, Industrial or Technology Park districts; those instead rely on minimum lot area and yard setback figures, and the code points to a separately maintained Unified Development Ordinance for further dimensional detail.

Because Chapter 102 governs unincorporated territory only, the 60 percent OI cap has no bearing on property inside Carrollton, Villa Rica, Temple, Bowdon, Whitesburg, Mount Zion, or Roopville.
