The Board of Adjustment is a quasi-judicial body under state law to provide relief in special cases where the exact application of the terms of the ordinance would be unduly restrictive and cause a hardship. Its function is to hear and decide upon the interpretation and the application of the provisions of the zoning ordinance in these cases. Although the board has certain discretionary powers in making its decisions, these powers have definite limits. The board must always abide by and comply with the powers granted to it by the local zoning ordinance and the state enabling act. The local zoning ordinance may not confer powers on the board which are not authorized by the state enabling act. The Board of Adjustment does not have regularly scheduled meetings. Their meetings are called on an as needed basis.
