Summary
You may convert an existing detached garage into an accessory dwelling unit, but the conversion must meet the UDO's ADU standards and the North Carolina Residential Code. Converting a garage into living space requires permits and dimensional compliance.
ADUs can be created by converting a basement... or converting an existing accessory structure such as a detached garage.
Full Breakdown
The Winston-Salem/Forsyth County UDO expressly recognizes converting an existing accessory structure, such as a detached garage, into an accessory dwelling unit as a way to create an ADU. A garage-to-ADU conversion must comply with the ADU size and setback rules (one ADU per lot, detached ADU capped at 1,000 square feet / 70% of the principal structure, 5-foot rear and side setback for new detached units, permanent foundation) and with the NC Residential Code for habitable space (ceiling height, egress, smoke alarms). Converting a garage to non-dwelling storage or workshop space still must respect accessory-structure and lot-coverage limits. A building permit is required for the change of use.
Violations & Fines
Converting a garage to living space without permits, or exceeding ADU limits, is a code and zoning violation; the county can require a permit, corrections to meet the Residential Code, or restoration of the prior use.
