76-2-323. Powers of board of adjustment. (1) The board of adjustment shall have the following powers:

(a) to hear and decide appeals where it is alleged there is error in any order, requirement, decision, or determination made by an administrative official in the enforcement of this part or of any ordinance adopted pursuant thereto;

(b) to hear and decide special exceptions to the terms of the ordinance upon which such board is required to pass under such ordinance;

(c) to authorize upon appeal in specific cases such variance from the terms of the ordinance as will not be contrary to the public interest, where, owing to special conditions, a literal enforcement of the provisions of the ordinance will result in unnecessary hardship and so that the spirit of the ordinance shall be observed and substantial justice done.

(2) In exercising the above-mentioned powers, such board may, in conformity with the provisions of this part, reverse or affirm, wholly or partly, or modify the order, requirement, decision, or determination appealed from and may make such order, requirement, decision, or determination as ought to be made and to that end shall have all the powers of the officer from whom the appeal is taken.
