N.C. Gen. Stat. § 160D-905

A local government ordinance based on health, safety, or aesthetic considerations that regulates the placement, screening, or height of the antennas or support structures of amateur radio operators must reasonably accommodate amateur radio communications and must represent the minimum practicable regulation necessary to accomplish the purpose of the local government. A local government may not restrict antennas or antenna support structures of amateur radio operators to heights of 90 feet or lower unless the restriction is necessary to achieve a clearly defined health, safety, or aesthetic objective of the local government.
