Every municipality which has enacted or enacts a zoning ordinance pursuant to this act or prior enabling laws, shall create a zoning hearing board. As used in this article, unless the context clearly indicates otherwise, the term “board” shall refer to such zoning hearing board.

The membership of the board shall, upon the determination of the governing body, consist of either three or five residents of the municipality appointed by resolution by the governing body. The terms of office of a three member board shall be three years and shall be so fixed that the term of office of one member shall expire each year. The terms of office of a five member board shall be five years and shall be so fixed that the term of office of one member of a five member board shall expire each year. If a three member board is changed to a five member board, the members of the existing three member board shall continue in office until their term of office would expire under prior law. The governing body shall appoint two additional members to the board with terms scheduled to expire in accordance with the provisions of this section. The board shall promptly notify the governing body of any vacancies which occur. Appointments to fill vacancies shall be only for the unexpired portion of the term. Members of the board shall hold no other elected or appointed office in the municipality nor shall any member be an employee of the municipality.
