How to Search the Marin County Jail Roster

The Marin County Public Booking Log is the official inmate search tool. The Sheriff's Detention Bureau links it, and it lists people booked into the county jail in the last 48 hours who are still in custody, plus a full current-custody list. The Sheriff releases the data under the California Public Records Act. The search field is last name, and it is optional, so you can also browse the recent list without a name.

The roster updates as people are booked and released, so the same search can look different a few hours apart. Bail shown on the log can be approximate, and the Sheriff asks people to call the jail for the exact figure. If a name does not appear, the person may have been released, booked elsewhere, or never held in Marin custody at all.

The booking log, visitation links, and money and mail rules all sit under the Detention Bureau.

Start at the Sheriff's Detention Bureau page to reach the booking log and the custody services.

That page is the hub, so it links the search itself along with bail, visiting, and PREA information in one place.

1. Open the Public Booking Log from the Detention Bureau page.
2. Enter a last name or browse the last 48 hours of bookings.
3. Open a record to read the charges, agency, and bail.
4. Check the next court date listed for the booking.
5. Call jail information at 415-473-6653 for exact bail.

Marin County Booking Log Search Fields

The booking log keeps its inputs simple, which is good when you only know a name. You search by last name or use the filters for recent and current custody. The table below matches what the Sheriff documents on the public page.

If a person was released or never booked into Marin custody, the booking log will not show them. The log is current and recent custody only, so an older booking needs a different source.

What a Marin County Inmate Record Shows

An inmate record on the booking log covers the basics of a current stay. Based on the Sheriff's own description, a record can show the fields below. It does not include classification, medical or mental health data, or internal movement, since those are not public.

For the full charge and case history behind a booking, the court file holds far more. See the Marin County court records page and the arrest records page for the case side of a booking.

The Marin County Jail

The county jail is run by the Sheriff's Custody Division. It sits at 13 Peter Behr Drive on the Civic Center grounds, built underground into the hillside, with a tunnel that moves people into the court areas. The jail houses men and women booked for law violations or sentenced by Marin courts. No one under 18 is held there except in cases the law requires. People in transit to another jail or prison may also be held for a short time. State jail standards under Title 15 and Title 24 govern how it runs.

The Custody Division page explains the jail's operations, the visiting schedule, and the money and mail rules.

Those details are posted on the Sheriff's Custody Division page.

The same page reports that in 2022 the jail booked 5,454 people and held an average daily population of 245.

What the Sheriff's Detention Bureau Handles

The jail is one part of a larger operation. The Detention Services Bureau is responsible for staffing the county jail, providing bailiff and security services for the Marin County courts, and transporting inmates. It is split into three parts. The Custody Division runs the jail itself. The Court Services Division provides the bailiffs you see in the courtrooms. The Transportation Unit moves people between the jail, the courts, and other facilities.

That structure is why a single Sheriff's office touches arrest, custody, court security, and transport. A person booked into the Marin jail may be moved through the Civic Center tunnel for a hearing, then returned to custody, all within the same bureau. The booking log reflects the custody side of that work.

The Booking Process and Inmate Phone Calls

Booking is the intake step that creates the record you search. Staff log the charges, the arresting agency, and the custody details that feed the public log. Under Penal Code 851, an arrested person has the right to three free completed local calls, to an attorney, a bail bond agent, a relative, or another person. Nonlocal calls are at the arrestee's expense.

Once a person is housed, the phones change. Inmates use outgoing phones in the housing units only, collect or prepaid. They cannot receive incoming calls, and custody staff do not take phone messages for inmates. A family emergency goes through the housing sergeant line rather than a message to the inmate.

Posting Bail at the Marin County Jail

The jail accepts bail 24 hours a day. That covers a person held in Marin custody or held elsewhere on a Marin warrant. Some bookings are no-bail, which means release waits for a court appearance.

There are four accepted ways to post bail. You can pay the full cash amount, bring a cashier's check or a money order payable to the Marin County Jail, or use a surety bond from a California-based bail bond company. Because the log's bail figure can be approximate, confirm the exact amount with the jail before you pay.

The exact-bail call matters more than people expect. Posting the wrong amount can delay a release, and a surety bond carries a fee you do not get back. The jail's information line at 415-473-6653 is the place to confirm the current figure and whether the booking allows bail at all. If a person is held on a no-bail warrant, no payment will secure release until a judge acts on the case.

Marin County Jail Visitation

Visits must be scheduled at least 24 hours in advance. You can book through the GTL VisitMe website, the VisMobile app, or the kiosk in the jail lobby. Walk-up visits are not accepted. Each inmate is allowed one 30-minute onsite visit and one 25-minute video visit per day. Visitors clear a metal detector, and only one key may be carried into the visiting room.

The visiting times below come from the Custody Division schedule. Weekend hours are shorter than weekday hours.

Minors must come with a parent or legal guardian and carry valid school, state, or passport ID. Up to three people may share a visit. Gang-related clothing and revealing attire are not allowed.

Adult visitors need a valid government photo ID. The jail accepts a U.S. driver's license or state ID, a U.S. passport, a U.S. military ID, a foreign passport, or a U.S. consular or matricular card. A recent DMV receipt with an old photo ID also works. If a medical condition keeps a visitor from clearing the metal detector, the visitor is patted down instead, and failing to clear can mean the visit is denied. Lockers in the lobby hold personal items for a quarter.

Mail, Money, and Commissary

Money and packages run through outside vendors, not the lobby window. Inmate trust deposits go through Access Corrections by website, phone, or lobby kiosk, and care packages come from the jail's package vendor. Prepaid phone and tablet services run through the GTL and ConnectNetwork systems. A money order by mail must be payable to the Marin County Jail and include the inmate's name and ID number.

• Trust deposits through Access Corrections, by web, phone, or kiosk.
• Care packages through the jail's commissary package vendor.
• Prepaid phone and messaging through GTL and ConnectNetwork.
• Money orders by mail, payable to the Marin County Jail.

Inmates get unlimited mail, but it is opened and searched for contraband first. Hardback books are not allowed, and paperbacks and magazines must come from a publisher or bookstore. Cash sent in the mail is removed and handled under jail procedure. Marin added enhanced mail screening through a dedicated vendor to cut down on contraband.

Release Notifications and Records Not Shown

The booking log shows current and recent custody, not future release. To track a custody change, the Sheriff points to VINELink, the victim notification service, which can send an alert by phone, email, or text. For the steps to confirm a release and to set up notifications, see the released inmates page.

Some data never appears in public results. Classification, medical and mental health records, internal movement, security risk notes, disciplinary files, and protected identifiers are not public. For an active order rather than a booking, see the warrant records page, and for jail population numbers, see inmate population data.

Inmate Safety and PREA

The Sheriff's Office states a zero-tolerance policy for sexual abuse, harassment, assault, and retaliation in the jail, in line with the federal Prison Rape Elimination Act. Reports are taken seriously, and the jail posts a confidential crisis line run by Community Violence Solutions' Rape Crisis Center for anyone who needs help.

For a medical or psychological concern about someone in custody, the custody FAQ directs families to the housing sergeant rather than the general line. Prisoner Services can also help arrange a visit for an inmate with mental illness. These are separate from the booking log, but they matter to families using the roster to plan contact with someone inside.
