Coweta County, GA Accessory Structures: Shed & Carport Rules (2026)

Article 4 of the Zoning and Development Ordinance sets Coweta County's baseline yard rules, and Section 45 extends those same setbacks to accessory buildings such as storage sheds, detached garages, and workshops, with one carve-out: an accessory building may sit as close as five feet to a rear or side lot line even where the district's normal side or rear setback runs wider, unless another provision of the ordinance imposes a stricter limit. That five-foot allowance is not a blanket rule for every district; it only applies unless further restricted, so a homeowner still has to check the dimensional table in Article 23 for the applicable zoning district (for example, RC Rural Conservation carries a 25-foot rear and 15-foot side setback baseline) before assuming the reduced five-foot line applies.

Section 47 layers on a separate spacing rule: no accessory building can be located closer than ten feet to the principal house or to any other accessory building on the same lot, so a shed cannot be tucked directly against the back porch or wedged next to a detached garage. Section 46 covers the case where a shed or accessory building is physically attached to the house by a breezeway or passageway; in that scenario the accessory structure must meet the same minimum yard setback as the principal building itself, not the reduced five-foot accessory setback, and the connecting breezeway must be covered and built of material acceptable to the building official.

Section 43 caps residential lots, outside group developments and Village Centers, to one principal building with its customary accessory buildings, meaning a homeowner cannot simply build a second small house and call it a shed.
