The ADU must be clearly subordinate in size to the primary dwelling unit

Owner-occupancy requirements may apply depending on the specific zoning district

Detached ADUs must comply with setback requirements from property lines

Adequate off-street parking must be maintained on the property

All ADU projects require proper building permits from the City of Columbia's Building and Site Development Division
