The Atlanta City Council approved an ordinance to amend Chapter 16 of the City of Atlanta Code of Ordinances, the Zoning Ordinance. The amendment specifically modifies the regulations concerning additional dwelling units (ADUs) within various residential zoning districts. This decision aims to increase housing density and flexibility by permitting more ADUs under specific conditions, addressing the city's housing supply challenges. The changes include revised setback requirements, maximum size limits, and parking provisions for ADUs. The council's decision followed a series of public hearings and a recommendation from the Zoning Review Board.
