Trenton Correctional Institution

Trenton Correctional Institution is a level 2 prison for male inmates that is located in Trenton, South Carolina. It is operated by the South Carolina Department of Corrections, and can house approximately 650 young male offenders.

Trenton houses young adult offenders who are sentenced under the Youthful Offender Act (YOA), young adult offenders whose crimes do not qualify for YOA sentencing, and adult straight-time offenders.

Level 2 facilities are medium-security institutions. Housing is primarily double bunk, cell type or double-bunk cubicles. With single-fenced perimeters and electronic surveillance, level 2 institutions provide a higher level of security than level 1 facilities.
