What is an ADU and can I add one in Johns Creek?

A Johns Creek ADU, short for accessory dwelling unit, is a secondary living space, attached, detached, or converted from a garage or basement, built on the same lot as a primary home. Whether a specific Johns Creek lot can add one depends on that property's zoning designation under Fulton County or city code, since Georgia has no single statewide ADU law that applies everywhere the same way. Confirm the zoning for a specific parcel with the Johns Creek planning department before assuming either answer.
