S.D. Codified Laws § 7-18-22

A county may require that the promoters of a special event secure a permit from the county before a special event may be conducted within the county unless the special event is carried on exclusively within the boundaries of a municipality. For the purposes of this section, a special event includes a fair, carnival, concert, public exhibition, or similar gathering except for special events sponsored, in whole or in part, by an accredited South Dakota educational institution. The promoter of a special event shall apply to the county treasurer upon forms provided by the county treasurer for a permit required by this section. The board of county commissioners may by resolution establish fees for a special event permit.
