Garage conversion rules in Roswell, GA — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Converting a garage to habitable space (bedroom, office, ADU) in Roswell requires a building permit, must meet residential energy code (insulation, windows, mechanical), and may require additional off-street parking to replace the converted spaces. ADU conversions are subject to the same UDC zoning rules as new ADUs.
Garage conversions are one of the most common Roswell remodeling projects. The Building Department requires a permit; converted space must meet the residential energy code (insulation, fenestration), have egress windows or doors per IRC §R310, and meet ceiling-height minimums. If the conversion adds bedrooms, the home's septic system (where applicable) and electrical service may need upgrades. The UDC also generally requires two off-street parking spaces per dwelling, so converting a 2-car garage to habitable space may require adding parking elsewhere on the lot - often a widened or extended driveway. Converting to an accessory dwelling unit requires the property's zoning district to allow ADUs and triggers the UDC ADU rules.
Unpermitted garage conversions are a Building Code violation citable in Municipal Court with fines up to $1,000 per day. The conversion may be ordered reversed if it lacks egress, ceiling height, or fire-separation. Real estate disclosure issues at resale are also common.
