The concurring vote of four-fifths of the members of the Board of Adjustment - six (6) of the seven (7) voting members - shall be necessary to approve any variance of the ordinance. The concurring vote of a majority of the members of the Board shall be necessary to reverse any order, requirement, decision, or determination of the Zoning Enforcement Officer of the City of Claremont, or to decide in favor of the applicant any matter upon which it is required to pass under the ordinance.

In accordance with N.C.G.S. 160D-109(d),members of the Board of Adjustment shall not participate in or vote on any quasi-judicial matter in a manner that would violate affected persons' constitutional rights to an impartial decision maker. Impermissible violations of due process include, but are not limited to, a member having a fixed opinion prior to hearing the matter that is not susceptible to change, undisclosed ex parte communications, a close familial, business, or other associational relationship with an affected person, or a financial interest in the outcome of the matter. If an objection is raised to a board member's participation at or prior to the hearing or vote on that matter and that member does not recuse himself or herself, the remaining members of the board shall by majority vote rule on the objection. For purposes of this section, a close familial relationship means a spouse, parent, child, brother, sister, grandparent, or grandchild. The term includes the step, half, and in-law relationships.12 (G.S. 160D-109(d), (e), (f)).
