S.C. Code Ann. § 6-29-780: Board of zoning appeals; membership; terms of office; vacancies; compensation.

(A) As a part of the administrative mechanism designed to enforce the zoning ordinance, the zoning ordinance may provide for the creation of a board to be known as the board of zoning appeals. Local governing bodies with a joint planning commission and adopting a common zoning ordinance may create a board to be known as the joint board of appeals. All of these boards are referred to as the board.

(B) The board consists of not less than three nor more than nine members, a majority of which constitutes a quorum, appointed by the governing authority or authorities of the area served. The members shall serve for overlapping terms of not less than three nor more than five years or after that time until their successors are appointed. A vacancy in the membership must be filled for the unexpired term in the same manner as the initial appointment. The governing authority or authorities creating the board of zoning appeals may remove any member of the board for cause. The appointing authorities shall determine the amount of compensation, if any, to be paid to the members of a board of zoning appeals. None of the members shall hold any other public office or position in the municipality or county.
