Classification and Housing
Inmates at the Mariposa County Jail are classified and housed based on a classification system that includes booking status, current and past behavior, and nature of current and past charges.
All inmates are locked down for twenty-four hours to confirm their classification status unless they have been pre-classified prior to admittance. The three types of housing at the jail are general population, administrative segregation, and protective custody.
- General Population: Inmates with good behavior are housed in the general population, and they have access to all privileges and programs.
- Administrative Segregation: If an inmate chooses not to obey the rules or are a threat to the safety and security of the facility, they are housed in Administrative Segregation. Access to privileges and programs can be denied while in this housing area. There are two types of Administrative Segregation -- open and lockdown.
- Inmates in open segregation are allowed out of their cells during the day, but are required to be in lockdown during the period from 11 p.m. and 6 a.m.
- Lockdown Segregation is reserved for high security inmates. They are allowed out for one hour each day to have access to telephone, shower and dayroom for exercise.
- Protective Custody: Inmates needing protection from other inmates are housed in Protective Custody. An inmate may request protective custody at any time while they are in jail. Access to privileges and programs may be limited while an inmate is in protective custody.
