North Carolina General Statutes Chapter 153A. Counties § 153A-45. Adoption of ordinances

To be adopted at the meeting at which it is first introduced, an ordinance or any action having the effect of an ordinance (except the budget ordinance, any bond order, or any other ordinance on which a public hearing must be held before the ordinance may be adopted) must receive the approval of all the members of the board of commissioners. If the ordinance is approved by a majority of those voting but not by all the members of the board, or if the ordinance is not voted on at that meeting, it shall be considered at the next regular meeting of the board. If it then or at any time thereafter within 100 days of its introduction receives a majority of the votes cast, a quorum being present, the ordinance is adopted.
