The booking log has one search field and it is optional, so an empty search returns everyone currently in the jail. Start with a name below and we will find them.

Marin County publishes a live roster called the Public Booking Log, released under the California Public Records Act. It covers two overlapping groups at once: everyone booked in the last 48 hours who is still in custody, and the complete in-custody list as of the moment you run the search. It is a genuinely useful tool, and it comes with one warning printed by the county itself, which is that the bail figure it shows may be an approximation.
The county’s own disclaimer defines the scope precisely, and it is worth reading closely because it explains most of the confusion families run into.
The log holds public data about people arrested and booked into the Marin County jail in the last 48 hours who are still in custody, and also a complete list of everyone in custody at the time the search is run. It is published under the California Public Records Act, Government Code 6254 f (1).
Two things follow from that. Someone booked three weeks ago and still held will appear, because they are on the current in-custody list. Someone booked yesterday and released this morning will not, because they are not.
There is one field, labelled last name, and it is marked optional.
Type a last name and submit. Leave it empty and submit, and you get everyone currently in the jail, which on an average day is around 250 people. That is a reasonable list to scroll if you are unsure of the spelling, and it is the workaround for a hyphenated or compound surname that the search does not match.
The Sheriff’s Office describes the result in its own words. The booking log or jail staff will confirm:
That last item is specific to Marin and worth knowing. Someone booked on an under-the-influence charge is held a minimum of four hours before they can be released, so the log gives a rough answer to “when can I collect them.”
The county prints this above the results: the bail amount indicated may be an approximation, and for exact bail information you should contact the jail at 415-473-6653.
Take that literally before you move money. Bail is set by schedule and then adjusted by a judge, and the roster is showing you a figure from a system that may not have caught up. A bondsman working from the roster number can be working from the wrong number.
Bail itself is accepted at the jail 24 hours a day, in cash, by postal or bank money order made out to the Clerk of the Court, or through a surety bond from a California-based company. Personal checks are never accepted for bail.
They were released. No information is provided on anyone not currently in custody, and there is no release history to browse.
They were booked minutes ago. The list is generated live, but a booking has to finish before it lands.
They are out of the building for the day. The Sheriff’s Transportation Unit moves people to medical, x-ray and dental appointments, and to state prisons and mental hospitals around California. That is a real and published reason a record can look odd on a given day.
The name is spelled differently. Records use the legal name. Submit an empty search and scan the full list.
They were never in Marin custody. A neighbouring county, the California Department of Corrections and Rehabilitation (CDCR) or the Federal Bureau of Prisons (BOP) each run their own separate lookups.
Marin County partners with VINE, the Victim Information and Notification Everyday service, so a victim of a crime can be notified automatically when the custody status of someone in this jail changes. That is the only published way to be alerted rather than having to keep checking.
The person’s name and ID number are what every other process at this jail runs on. The mail routing line needs them. An Access Corrections deposit needs the ID number. The visit booking needs them. Copy both down the first time you find the record, rather than looking it up again each time.

Use the Public Booking Log at apps.marincounty.gov/BookingLog. There is one field, an optional last name. Enter a surname and submit, or leave it blank to return the complete list of everyone currently in custody, which is usually around 250 people and is the fastest way around a spelling problem.
Inmate SearchWhether the person is in custody, the charges they were booked on, which police agency booked them, the bail amount, and the next court appearance date. For someone booked under the influence it also indicates how long before they become eligible for release, with a minimum four-hour stay.
Inmate SearchBecause it warns that the figure shown may be an approximation, and directs you to call the jail at 415-473-6653 for the exact number. Bail is set by schedule and then changed by a judge, and the public log can be showing a figure the courts have already moved. Confirm by phone before paying anyone.
Inmate SearchMost likely a release, since the log carries only people currently in custody and publishes nothing about anyone let out. There is another possibility worth knowing: the Sheriff's Transportation Unit moves people out for medical, x-ray and dental appointments and to state prisons and hospitals elsewhere in California. Call 415-473-6655 if a release does not fit.
Inmate SearchMarin County does not publish an update frequency or an as-of timestamp. The only wording it gives is that the list reflects everyone in custody at the time the search is run, which means it is generated live rather than from a nightly file. We would rather tell you that than invent a refresh interval.
Inmate SearchCall 415-499-7316, which the Sheriff's Office publishes specifically for people who cannot use the online log. Jail staff will confirm the same information the log carries. Note that Marin publishes four different jail numbers for different purposes, so this is the one for a custody lookup rather than the general line.
Inmate SearchIf you are the victim of the crime, yes. Marin County partners with VINE, the Victim Information and Notification Everyday service, which notifies registered victims when someone's custody status changes. For everyone else there is no alert, and checking the log is the only route.
