The Main Jail is located at 221 East Main Street in Lancaster. This facility was built in 1966 and is a medium - maximum level security facility. All male prisoners charged with violent and serious offenses are booked and housed in this facility. The average inmate population for the Main St. Jail was approximately 73 inmates in 2014. This is a decrease from the 2013 average of 85 inmates. This facility's maximum rated capacity set by the state is 27 prisoners.
Due to design of the facility there isn't any recreational or programming space for prisoners. Attorney's, mental health counselors and psychologists, detectives and other criminal justice professionals needing to meet with or interview prisoners must do so in a holding cell in the booking area. Prisoner meals are transported from the MSJ to the Main Jail three times a day due to the lack of any kitchen facilities at the Main Jail.
The Main Jail also contains administrative offices for the Sheriff, Chief Deputy, Jail Administrator, sex offender registration officer, pay-to-stay coordinator, jail shift supervisor, evidence room & clerk, maintenance and community policing officer.
