Jails — operated by counties
Texas county jails are operated by sheriffs under Local Government Code Chapter 351, with regulation by the Texas Commission on Jail Standards. Who is held: pretrial detainees who cannot post bond; misdemeanor offenders serving sentences (up to 1 year for Class A, up to 180 days for Class B); probation/parole violators awaiting hearings; defendants serving "shock probation" or jail time as condition of probation. Population: approximately 60,000-65,000 statewide across 254 counties. Largest: Harris County Jail (Houston) — approximately 9,000 inmates; Dallas County Jail — approximately 5,500; Bexar County Jail (San Antonio) — approximately 4,000.
Prisons — operated by TDCJ
Texas state prisons are operated by the Texas Department of Criminal Justice — the second-largest prison system in the U.S. Who is held: convicted felons serving sentences of 1+ year (third-degree felony and above). Population: approximately 130,000 inmates across 95 facilities. Security levels: Minimum (G1-G2 custody), Medium (G3), Maximum (G4-G5), Administrative Segregation. Notable facilities: Polunsky Unit (Livingston) — death row men; Mountain View Unit (Gatesville) — death row women; Huntsville Unit ("the Walls") — execution chamber; Beto Unit (Tennessee Colony); Allred Unit (Wichita Falls); Coffield Unit (Tennessee Colony); Estelle Unit (Huntsville). Texas prisons offer education, vocational training, and treatment programs unavailable at county jail level.
State jails — Texas's unique third category
Texas created state jails in 1993 to address the gap between misdemeanor jail and felony prison. Who is held: state-jail felony offenders (180 days-2 years) — primarily lower-level theft, possession of controlled substances under 1 gram, criminally negligent homicide, certain forgery offenses. Facilities: 19 state jail facilities across Texas. Key difference from prison: no parole eligibility; offenders serve calendar time with limited good-time credits. Programs: substance abuse treatment, education focus, transitional support to community. The state-jail system was designed for first-time felony offenders without sending them to mainline prison — though the no-parole structure has been criticized as actually harsher than third-degree felony service for some offenders.
Federal vs. state — separate systems
Federal prisoners are housed in Bureau of Prisons facilities, not state prisons. Federal facilities in Texas include: FCI Beaumont (Beaumont) — federal correctional complex; FCI Fort Worth — medical center; FCI Bastrop — low/minimum security; FDC Houston — federal detention center; USP Pollock (LA, near TX border) — high security. Federal pretrial detention is at FDCs or contract county facilities. The federal and state systems are structurally separate — federal inmates serve federal sentences in federal facilities regardless of where the offense occurred. Federal sentences have no parole (only good-time credit up to 54 days/year and First Step Act earned time credits).
Practical differences — defendant experience
Several practical differences affect defendants. Length of stay: jails are typically days to months; prisons are years. Location: jails are typically in/near defendant's county; prisons can be hours from family. Programming: prisons offer education, vocational training, treatment; jails are typically warehousing. Health care: both have constitutional minimum standards; prison medical care is generally more comprehensive due to longer stays. Work: prison inmates can earn limited compensation; jail inmates typically don't work. Communications: both have phone and mail; prisons have more structured email and video visitation. Visitation: jails typically have shorter, more frequent visits; prisons longer but less frequent.
