South Fulton, GA Building Setbacks & Zoning: Lot Coverage Limits (2026)

The Zoning Ordinance's Article 10 groups A-1 among the city's inactive zoning districts, meaning no new property can be rezoned A-1, but Section 1006.05 still governs every lot that already carries that classification. Its lot-coverage rule is a single sentence: buildings on an A-1 lot, counting accessory buildings along with the principal structure, cannot cover more than 30 percent of the gross lot area. That cap sits alongside the district's other Section 1006 standards, including a 45-foot, three-story height limit and a rear yard that grows from 25 feet to 75 feet where the lot backs up to a single-family district.

Table 4-1 in Section 403.01, which governs the city's active zoning districts, shows lot coverage is not uniform across South Fulton. The TR Townhouse Residential district caps coverage at 50 percent, the A Multi-family district at 40 percent, and both the A-L Apartment-Limited and O-I Office-Institutional districts at 70 percent. Single-family districts, R-1 through R-6 and AG-1 Agricultural, list no separate numeric lot-coverage figure in that table; the Community Development and Regulatory Affairs Department instead controls building footprint on those lots through minimum setbacks, minimum lot size, and minimum lot width requirements. Commercial and industrial districts such as C-1, C-2, M-1, and M-2 likewise carry no separate lot-coverage percentage in the table, leaving setbacks and Article 4 buffer requirements as the operative footprint controls there.
