*** Cancellation of Jail Visits because of Coronavirus ***

To prevent the spread of COVID-19 into the Contra Costa County detention facilities, the Office of the Sheriff has temporarily canceled all professional, official, and social visits at the Martinez, West County, and Marsh Creek Detention Facilities. However, attorney visits will continue with access to non-contact visit rooms only. The cancellation will be reassessed as conditions change.

The Martinez Detention Facility (MDF) opened in 1981 and is one of three detention facilities operated by the Contra Costa County Office of the Sheriff. The MDF is a maximum security facility and the primary point of intake for all arrestees booked in Contra Costa County.

The MDF houses a diverse population of both pre-sentenced and sentenced inmates who do not qualify for less restrictive environments.

The MDF administration and staff work in collaboration with many community-based organizations to provide educational and rehabilitative programs for the inmates. The MDF also offers a broad range of medical and psychiatric services to the inmates provided by physicians, psychiatrists, dentists, nurses, and mental health clinicians.

The MDF staffing consists of both sworn and professional staff members (assigned to operational and support roles) who work diligently to provide a safe and clean housing environment for inmates.
