State jails house inmates convicted of state jail felony offenses, which include lower-level assault and drug, family, and property offenses. In addition the Texas Board of Criminal Justice designated state jails as transfer units for individuals who are bound for prisons. Each individual in a state jail who is convicted of a state jail offense may not be held for longer than 2 years, nor may he or she be held for shorter than 75 days. Individuals may not parole or have mandatory supervision release from state jails.
