Garage conversion rules in Fayetteville, AR — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Fayetteville allows converting a garage to living space with a building permit. The conversion must meet residential code for egress, insulation, and ventilation. An interior ADU under UDC Sec. 164.19 is a common pathway.
Converting a garage into habitable space in Fayetteville requires a building permit and compliance with the 2021 Arkansas Fire Prevention Code (2021 IRC with amendments). The new space must meet standards for egress windows, ceiling height, insulation, ventilation, and smoke and carbon-monoxide alarms, with electrical and plumbing work inspected. Because a converted garage becomes an accessory or additional dwelling, owners commonly permit it as an interior ADU under UDC Sec. 164.19, where up to two ADUs totaling 1,200 square feet are allowed on a single-family lot. Final inspection and a certificate of occupancy are required before the space is used for living.
Converting without a permit triggers a stop-work order and retroactive fees. Occupying before final inspection is prohibited; a non-compliant conversion may have to be restored to a garage.
