Garage conversion rules in Orange County, NC — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Turning a garage into living space in Orange County is a change of occupancy that needs a building permit. The room must meet the NC Residential Code for egress, insulation, and smoke and CO alarms.
A garage conversion changes the space to habitable room, so a building permit is required before work begins under the NC State Building Code, from Orange County Building Inspections in unincorporated areas, or Chapel Hill or Carrboro inside town limits. The inspector checks egress for any bedroom, ceiling height, insulation to the energy code, and interconnected smoke and carbon-monoxide alarms. New wiring, heating, or plumbing draws its own permits. If the conversion creates a separate dwelling unit, local zoning decides whether that second unit is allowed. Lost covered parking can matter for zoning compliance.
Converting a garage to a bedroom without a permit is unlawful habitable construction that draws a stop-work order, penalties, and retroactive permitting. Missing egress or alarms fails inspection.
