The Texas Commission on Jail Standards sets rules and procedures, establishes minimum standards for the construction, maintenance, and operation of county jails. The Tarrant County Confinement Bureau has passed this certification every year since 1995. In October 2012, Tarrant County received certification on the Lon Evans Correction Center, a 207,700 square foot, five-story maximum-security facility. This facility is classified by the U.S. Green Building Council (USGBC) Leader in Energy Environment Design (LEED) as a gold certified facility. A gold certification, the USGBC’s second highest certification, was awarded for the efficient use of energy, water and material.
The Confinement Bureau is staffed with approximately 1,000 men and women certified as detention officers or peace officers (sheriff's deputies) by the Texas Commission on Law Enforcement (TCOLE). The Tarrant County Jail has a capacity of approximately 5,000 prisoners and is comprised of five facilities.
