Full Breakdown

DeKalb County has no county-wide mandatory green building code; new construction instead follows the state-adopted International Energy Conservation Code under Chapter 7. What the zoning ordinance offers is a voluntary incentive: Table 2.6 under Sec. 2.12.5, applicable to the RSM (Small Lot Residential Mix) District, grants a 50-percent increase over the base maximum density when the applicant certifies that buildings, as designed, would be accredited by LEED, EarthCraft or a similar national green-building accreditation organization for energy- and water-efficient site and building design. The bonus applies only to subdivisions in the RSM district, not individual infill lots or other zones.

Violations & Fines

Claiming the Sustainability Elements density bonus without a valid LEED, EarthCraft or equivalent accreditation certification is grounds for the county to deny or reverse the approved bonus density under Sec. 2.12.5.

Frequently Asked Questions

Does DeKalb require green building certification?
No. LEED/EarthCraft certification is optional and only unlocks a density bonus in the RSM zoning district; it isn't required for a building permit.
Can an individual infill lot get the density bonus?
No. Sec. 2.12.5(C) limits density bonuses, including the sustainability bonus, to subdivisions and expressly excludes individual infill lots.
