Atlanta's zoning code limits lot coverage — the percentage of a lot that can be covered by structures and impervious surfaces — based on zoning district. Residential lot coverage limits typically range from 45% to 75% depending on the district. These limits work with the tree canopy and stormwater regulations to maintain Atlanta's urban forest character.
Lot coverage in R-1 and R-2 districts is typically limited to 45-55% of the total lot area. R-3 through R-5 districts allow higher coverage, up to 75%. Lot coverage includes the footprint of all structures (main building, garage, accessory structures), driveways, patios, walkways, and other impervious surfaces. Open decks may be partially excluded from coverage calculations. The Floor Area Ratio (FAR) also limits total building volume relative to lot size. In addition to zoning limits, the city's tree protection ordinance and stormwater management requirements effectively constrain development intensity. Properties in the BeltLine Overlay District may have modified coverage standards to encourage transit-oriented development.
Exceeding lot coverage limits is a zoning violation that prevents issuance of building permits and Certificates of Occupancy. Retroactive violations may result in fines up to $1,000 per day and orders to remove excess impervious surface. Variances require Board of Zoning Adjustment approval with demonstrated hardship.
