The system comprises eight jails, with approximately 55,000 annual bookings administered by 800 deputy sheriffs.
The newest San Francisco jail complex is located near the Hall of Justice on Seventh Street.
This main complex jail is a "direct supervision facility [that] has become a national model for program-oriented prisoner rehabilitation."
The first jail established in San Francisco was demanded by the Alcalde, later first mayor, John W. Geary and set up in a beached brig, the Ephemia on the shore of Yerba Buena Cove.
The Ingleside Jail opened in 1872 on the present site of the City College of San Francisco.
