Full Breakdown
Atlanta Code of Ordinances Sec. 16-06.008, the minimum-yard-requirements section for the R-4 Single-Family Residential District, sets two bulk limits together: a maximum floor area ratio of 0.50 and a maximum lot coverage of 50 percent of total lot area. R-4 is the city's standard 9,000-square-foot-minimum single-family district. Other single-family districts (R-1, R-2, R-2A, R-2B, R-3, R-3A, R-4A, R-4B, R-5) carry their own bulk tables in their respective chapters, and SPI overlay districts and historic districts can override these figures for a specific parcel, so confirm the zoning classification on file with the Office of Zoning and Development before relying on the 50 percent figure.
Violations & Fines
Building or additions exceeding 50 percent lot coverage cannot receive a building permit from the Office of Buildings without a variance from the Board of Zoning Adjustment under Part 16, Chapter 26.
