The Department of Corrections has 21 institutions and they are categorized into four distinct custody levels: close security, medium security, and minimum security which includes community-based pre-release/work centers for those with Minimum-Out Custody classification. The architectural design of the institution, type of housing, operational procedures, and the number of security staff determine an institution’s custody. Inmates are assigned, based on their designated custody, to institutions to meet their specific security, programming, medical, educational, and work requirements.


Minimum security facilities are the lowest custody facilities that house inmates with either a Minimum-Out (MO) or Minimum-In (MI) custody classification. Please be advised all Minimum-security facilities may house both Minimum-Out and Minimum-In custody inmates. These facilities house typically non-violent inmates with relatively short sentences or time to serve remaining. Housing is primarily double bunk, open-bay wards with unfenced perimeters.

Inmates classified as Minimum-Out are primarily located at the community-based pre-release/work centers and are eligible for work release programs when within 36 months of their release. These units are work and program oriented, providing intensive specialized programs that prepare the inmates for release to the community.

Inmates classified as Minimum-In are primarily located at these minimum-security institutions but are not yet eligible for the work-release programs. The operational procedures for those in the Minimum-In custody classification provide a higher level of security than for those classified as Minimum-Out.


Medium security facilities are more secure facilities designed to house offenders with a classification custody of ME. Housing is primarily double bunk cell type with some institutions having double-bunk cubicles. With single-fenced perimeters and electronic surveillance, medium security facilities provide a higher level of security than minimum security facilities.


Close security facilities are high-security facilities designed primarily to house violent offenders with longer sentences, and inmates who exhibit behavioral problems. Housing consists of single and double cells, and all perimeters are double-fenced with extensive electronic surveillance. Inmates at close security facilities are closely supervised and their activities and movement within the institution are highly restricted.
