In the RS 6,000 single-family district, Union City requires a 20-foot front yard, a 20-foot rear yard, a 15-foot exterior side yard, and an interior side yard equal to 10% of lot width (5 to 10 feet). Other residential districts vary.
Per the Union City Residential Zoning Districts Development Standards (UCMC Title 18), required setbacks differ by district. RS 6,000: front 20 ft, interior side 10% of lot width (minimum 5 ft, maximum 10 ft), exterior side 15 ft, rear 20 ft. R-5000: front 20 ft, interior side 5 ft, exterior side 10 ft, rear 10 ft. Multi-family RM districts: front 20 ft, exterior side 10 ft, rear 20 ft. The front yard may be reduced by 5 feet where all parking is at the rear or entered parallel to the front, and the rear yard may be reduced where a qualifying portion of yard area remains.
Structures encroaching into required yards must be removed, relocated, or granted a variance. The Zoning Ordinance controls over any summary table in case of conflict.
