S.C. Code Ann. § 44-20-480

When the Office of Intellectual and Developmental Disabilities determines that the welfare of a client would be facilitated by his placement out of the home, the client must be evaluated by the office, and the least restrictive level of care possible for the client must be recommended and provided when available. The office shall determine which levels of care are more restrictive and is responsible for providing a range of placements offering various levels of supervision. The office may pay an individual or organization furnishing residential alternatives to clients under this section a reasonable sum for services rendered, as determined by the office.
