Minimum security facilities shall be designed only in conjunction with facilities which meet the requirements of Chapter 259, §§259.100-259.170 of this title (relating to Maximum Security Design) or §§261.100-261.171 of this title (relating to Existing Maximum Security Design). Inmates housed in minimum security facilities shall be assessed according to the provisions of Chapter 271 of this title (relating to Classification and Separation). Unlike jails or lockups for maximum custody and medium custody inmates, these facilities do not require stringent security measures. Maximum security spaces which are incorporated into the minimum security design shall meet the requirements of Chapter 259, §§259.100-259.170 of this title.
