N.C. Gen. Stat. § 160D-103

A local government may elect to combine any of the regulations authorized by this Chapter into a unified ordinance. Unless expressly provided otherwise, a local government may apply any of the definitions and procedures authorized by law to any or all aspects of the unified ordinance and may employ any organizational structure, board, commission, or staffing arrangement authorized by law to any or all aspects of the ordinance. Inclusion of a regulation authorized by this Chapter or local act in a unified development ordinance does not expand, diminish, or alter the scope of authority for those regulations.
