For the benefit of family members and friends of individuals currently detained in the Mariposa County Correctional Facility, our team of California criminal defense lawyers provide key information below. The following important topics are covered here:

1. Mariposa County Inmate Locator

The Mariposa County Sheriff does not provide an online inmate search function, but refers searchers to the California inmate locator website. There, you can plug in a name to see if your friend or loved one is currently in custody in Mariposa County. The jail website does offer a link to a daily pdf that lists new, incoming detainees. You can also call the jail directly at (209) 966-3616 to inquire about the status of an inmate.

2. Bail Bonding

Your friend or loved one may be given the opportunity to post bail and gain temporary freedom from incarceration. You can call the jail to get specific bail bonding information. Cash or cashier's check bail payment can be made at the jail or you can use the services of a bail bondsman.

3. Phone Communication with Inmates

Under California law, all criminal detainees have the right to three, free (local) phone calls from a detention center, including personal and legal calls. Family members and friends cannot call in to speak with a Mariposa County Jail detainee or inmate, nor will the staff take messages. If there is a verifiable emergency situation, you can call the facility at (209) 966-3616 and ask to speak to the Lieutenant.

The Mariposa County Adult Detention Center provides phones for inmates to use between the hours of 6:00 a.m. and 11:00 p.m. each day. Calls are made collect or funded with a pre-paid phone card. These cards must be purchased through approved channels. To set up an account and provide telephone funds, call Correctional Billing Services at 800-844-6500 or use the Legacy Inmate link provided on the Detention Center website.

It is important to note, inmate phone calls are subject to monitoring and recording. Thus, it will be in the best interest of your loved one to avoid speaking about pending criminal charges over the phone.

4. Mariposa Inmate Cash Accounts

Although Mariposa County Jail inmates have access to basic supplies, many will want to purchase additional comfort items from the commissary. Options include snacks/treats, toiletries, stationary materials, and other items. Commissary items are ordered weekly. In Mariposa, they are usually ordered Tuesday for a Thursday delivery.

Family and friends can contribute funds to inmate cash accounts for commissary, haircuts and other incidentals. The Mariposa Detention Center no longer accepts funds over the counter or money orders through the mail.

7. Life and Health at the Jail

Most incoming Mariposa County inmates are put on 24-hour, initial lockdown status, during which time they are classified according to criminal charges (current and past) and observed (or past) behavior. They will receive a housing assignment based upon these factors.

There are four types of housing classifications in the Mariposa County Adult Detention Center:

General Population: This includes non-violent inmates who have a history of good behavior. All privileges and programs are available here.

Administrative Segregation (Open): Privileges and access to programs may be denied in this unit, which houses inmates who pose a threat to safety/security or have committed rule violations. These inmates are allowed out of their cells in the daytime, but must be locked down from 11:00 p.m. to 6:00 a.m.

Lockdown Segregation: High security inmates are housed here, and allowed out of their cell for one hour a day. Telephone access may be restricted to inmates under disciplinary action.

Protective Custody: This unit keeps inmates who are segregated due to their own request or medical/mental health issues. Access to privileges and programs may be limited in protective custody.

All inmates receive an initial health screening. Necessary medical care and dental care is provided upon request, and inmates may be referred for mental health services. Family or friends can bring in prescription medication that is in the original container displaying the inmate's name. A physician at the jail will approve all medications before they are dispensed. One clear pair of prescription glasses (not reading glasses) may also be brought in for inmate use.

Programs and services offered to Mariposa Jail inmates include religious services and counseling and 12-step programs. There is outdoor recreation available, and inmates can exercise an hour each day.

Inmates can earn “good time” sentence deductions for obeying all rules and may also receive “work time” deductions for jobs done at the jail.

Mariposa County Corrections takes steps to comply with the Prison Rape Elimination Act (PREA) of 2003. There is a zero tolerance policy for sexual misconduct of any kind, and reports are encouraged. Inmates and family members can report incidents at the jail or through the National Sexual Assault Hotline: 800-656-4673.

A Work Furlough program and a Weekend Service program is facilitated by the Mariposa County Jail. Approved work release inmates will have full time employment in place prior to sentencing.
