S.D. Codified Laws § 7-18A-37
Any county may, by ordinance, require any person over eighteen years of age seeking employment with the county to submit to a state and federal criminal background investigation by means of fingerprint checks by the South Dakota Division of Criminal Investigation and the Federal Bureau of Investigation. The ordinance shall specify which occupations or positions require a criminal background check. The county may submit completed fingerprint cards to the Division of Criminal Investigation before the prospective new employee enters into service. Upon completion of the state and federal criminal background check, the Division of Criminal Investigation shall forward to the county all information obtained as a result of the check. Failure to submit or cooperate with the criminal background investigation is grounds for denial of employment.
