DeKalb County zoning limits total lot coverage by buildings and impervious surfaces. R-100 typically caps at 35% building coverage; tighter limits apply in transitional and watershed overlay districts.
DeKalb County Zoning Chapter 27 regulates maximum lot coverage. Residential districts generally cap building footprint coverage at 30 to 35% (R-100 at 35%) and total impervious coverage (buildings plus driveways, patios, pools, walkways) at a higher overall percentage. The county enforces tighter limits in the Chattahoochee River Corridor, the South River watershed, and Stream Buffer overlay zones under the Georgia Erosion and Sedimentation Act and local watershed protection ordinance. Permeable pavers may earn partial impervious credit when engineered. Lots exceeding coverage require stormwater mitigation plans. The Chattahoochee corridor triggers additional Metropolitan River Protection Act review.
Exceeding lot coverage: correction required, fines $500 to $2,500. May need to remove impervious area or install mitigation. Watershed overlay violations: daily fines and restoration.
