S.C. Code § 2-48-40
The construction of community correctional facilities, as authorized pursuant to this chapter, provides the courts with a less costly alternative to committing offenders to more secure state correctional institutions and assists in the supervision and rehabilitation of drug and alcohol and other nonviolent offenders, who can be incarcerated safely in community correctional facilities. The facilities may be used for furthering the reintegration of offenders into the community before their release. Facilities established pursuant to this chapter must be available as a means of providing sentencing alternatives for persons sentenced to incarceration in a state correctional facility. However, upon the approval by the Director of the Department of Corrections, the facilities may be made available to persons who otherwise would be sentenced to incarceration in a jail of the county, municipality, other local governmental, or multi-jurisdictional entity involved, if the inmates do not displace state inmates from participating in the programs.
