Garage conversion rules in Smyrna, GA — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Garage conversions in Smyrna require a building permit and must comply with the IRC and 2024 state codes. Off-street parking requirements must still be met. If creating an ADU, zoning provisions apply.
Converting a garage to habitable living space in Smyrna requires a building permit from the Building Division. The conversion must comply with the International Residential Code (IRC) as adopted by Georgia with amendments — covering egress, insulation, ceiling height, electrical, HVAC, and fire separation. If the conversion creates a second dwelling unit (ADU), Smyrna's ADU zoning provisions apply. The original off-street parking requirements for the property must still be met after conversion (i.e., parking cannot simply be eliminated). Applications are submitted online through the OpenGov portal.
Unpermitted conversion: $500 to $2,000. May require restoration to garage or retroactive permitting.
