ADU Rules in Winston-Salem, North Carolina

Winston-Salem is the seat of Forsyth County and the largest city in the western Piedmont Triad, alongside Greensboro and High Point. The city's history is inextricably tied to R.J. Reynolds Tobacco Company, whose legacy is visible throughout the city's architecture and its ongoing transformation from an industrial economy to one anchored by healthcare (Atrium Health Wake Forest Baptist, Novant Health), higher education (Wake Forest University), and creative industries. The city has embraced its arts identity, with a thriving performing arts scene and the nationally recognized innovation district.

No Statewide ADU Law — Joint UDO Governs

North Carolina has no statewide ADU preemption law. In Winston-Salem, land use is regulated through a joint city-county planning program administered by the Winston-Salem/Forsyth County Planning Board. The governing document is the Winston-Salem/Forsyth County Unified Development Ordinance (UDO), which applies to both city-incorporated areas and portions of the county. Identifying the correct jurisdiction for your parcel is the first step in any ADU project.

Permitted ADU Types

The Winston-Salem/Forsyth County UDO generally permits the following ADU types in residential districts:

• Detached ADU: A freestanding dwelling unit on the same lot as the primary residence
• Attached ADU: Connected to the primary structure with its own entrance
• Interior conversion: An existing portion of the primary dwelling converted to a separate unit

General Development Standards

Typical development standards (verify current requirements before planning):

• Maximum floor area: Detached ADUs are commonly limited to 800 sq ft or a percentage of the primary dwelling's square footage, with caps varying by district
• Setbacks: Rear and side setbacks in the range of 5–8 ft; the ADU cannot intrude into required setbacks
• Height: Generally limited to 20–24 ft or the height of the primary structure, whichever is less
• Lot coverage: ADU footprint counts toward maximum lot and impervious surface coverage limits
• Parking: One additional off-street parking space may be required depending on district

Special Considerations

• Winston-Salem Northern Beltway and airport corridors: Properties near Smith Reynolds Airport or the corridor of the Northern Beltway project may have height or use restrictions; verify with Planning
• Historic districts: Winston-Salem's West End, Ardmore, and other historic areas have local historic district overlays; the Historic Preservation Commission reviews modifications to contributing structures
• Tobacco legacy sites: Some neighborhoods adjacent to former tobacco facility sites may have environmental or deed considerations; consult with an environmental attorney if renovation involves older structures
• Flood zones: Properties near Peters Creek, Salem Creek, and other waterways may be in FEMA flood hazard areas
