S.D. Codified Laws § 11-4-19
Appeals to the board of adjustment may be taken by any person aggrieved or by any officer, department, board, or bureau of the municipality affected by any decision of the administrative officer to grant or deny the permit. No other appeal such as any relating to a ministerial act or other preliminary act to bring an application or matter before the board for hearing and a final decision on the merits is authorized by the section. Such appeal shall be taken within a reasonable time, as provided by the rules of such board, but not to exceed twenty-one days, by filing with the officer from whom the appeal is taken and with the board of adjustment a notice of appeal specifying the grounds thereof. The officer from whom the appeal is taken shall forthwith transmit to the board all the papers constituting the record upon which the action appealed from was taken. All appeals relating to a particular action or property shall be consolidated and heard on an expedited basis.
