If you’re looking for a jail in San Francisco, CA, don't just head to the Hall of Justice and expect to find everyone in one spot. It’s way more complicated than that. San Francisco actually runs several facilities, and honestly, one of the biggest ones isn't even inside the city limits. It's down in San Bruno.
Knowing which "pod" or building someone is in can feel like a maze. You've got intake, maximum security, and specialized medical wards all scattered around. If you are trying to find someone who just got picked up, you’re likely looking at County Jail #1. That’s the Intake and Release Center at 425 7th Street.

It’s a revolving door there. People getting fingerprinted, photographed, and—if they’re lucky—bailed out before they ever see the inside of a real cell block. But if they stay? That’s when things get specific.
Navigating the Jail San Francisco CA System
The San Francisco Sheriff’s Office (SFSO) oversees the whole operation. They manage a population that fluctuates, but usually sits around 2,000 people on any given day. It’s a mix of people waiting for trial and those serving shorter sentences for misdemeanors or specific felonies under California's realignment laws.
Where the facilities actually are
Basically, the system is split into three main hubs.
First, there’s the 7th Street complex in the city. This houses County Jail #1 (Intake) and County Jail #2. Jail #2 is a "New Generation" facility. It uses a pod design, which is basically a fancy way of saying it’s built for direct supervision. It’s also where all female inmates in San Francisco are housed.
Then you have the San Bruno facility. This is County Jail #3 (formerly known as Jail #5, but names shift around in local bureaucracy). It’s located at 1 Moreland Drive in San Bruno. Yes, it's in San Mateo County, but San Francisco owns the land. It’s the largest facility and is generally where people go for longer stays.
Finally, there are the Hospital Wards. If an inmate gets seriously sick or has a mental health crisis that the jail staff can't handle, they go to Wards 7D and 7L at Zuckerberg San Francisco General Hospital. It's a locked ward, so don't expect a standard hospital visit.

How to Find Someone (and Get Them Out)
If you're panicking because a friend or family member hasn't called, the first step is the SFSO Inmate Locator. You need their name or their "SF Number."
If they were just arrested, it might take a few hours for them to show up in the system. Booking isn't instant. It involves medical triage, warrant checks, and a whole lot of paperwork.
The Bail Reality
Bail is a hot-button issue in San Francisco. Under the Humphrey decision, judges have to consider a person's ability to pay. This means "cash bail" isn't as common as it used to be for lower-level offenses, but for serious charges, it’s still very much a thing.
You can post bail at the 425 7th Street lobby 24/7. They take cashier's checks, money orders, or you can go through a bail bondsman. Just keep in mind that bondsmen usually charge a 10% non-refundable fee.
Visiting Rules Are Strict
Don't just show up. You will be turned away.
Everything is scheduled now. You have to register through the GTL VisitMe website at least a day in advance. Also, San Francisco is pretty unique because all phone calls from the jail have been free since 2020. This was a huge deal for families who used to spend hundreds of dollars just to hear a loved one's voice.
What to wear (and what NOT to wear)
The dress code is surprisingly specific. No orange clothing—you'll look too much like the inmates. No "gang-related" attire, which is often left to the deputy's discretion. No mini-skirts or sheer tops.

- ID is mandatory: Unexpired government ID only.
- Lockers: You can't bring your phone or bag inside. There are lockers in the lobby.
- The 30-Minute Rule: Arrive 30 minutes early. If you're late, your slot is gone.
Health and Programs Inside
San Francisco jails are known for having some of the most robust programming in the country, though critics will say it’s still jail.
The Five Keys Charter School was actually the first high school in the nation to operate inside a county jail. Inmates can earn a GED or even take City College courses. There are also specialized programs like RSVP (Resolve to Stop the Violence Project) which focuses on restorative justice for men with violent histories.
For health, Jail Health Services (part of the SF Department of Public Health) handles the medical side. This is separate from the Sheriff's deputies. They deal with everything from detoxing inmates—which is a huge issue given the city's fentanyl crisis—to long-term psychiatric care in the Sheltered Living Units.
Recent Changes and Controversy
The system is constantly changing. In 2020, the city finally closed County Jail #4, which was located on the 7th floor of the Hall of Justice. It was a "linear" style jail—think old-school bars and dark corridors—and it was widely considered a seismically unsafe dungeon.
Closing it meant moving hundreds of people to the San Bruno facility, which created its own set of logistical nightmares for attorneys trying to visit their clients.
With the passage of Proposition 36 in California in late 2024/2025, the jail population is expected to shift again. The new law allows for "treatment-mandated felonies" for certain drug offenses. This means more people might be cycling through the jail for short stints if they fail out of mandated rehab programs.
Actionable Steps for Families
If you have someone in a jail in San Francisco, CA, here is exactly what you should do right now:
- Locate them immediately: Use the SF Sheriff Inmate Lookup tool. Note their SF Number; you will need it for everything.
- Don't talk about the case on the phone: Even though calls are free, they are recorded. Prosecutors listen to these. Period.
- Set up a TouchPay account: If the person needs commissary (extra food, hygiene items), you'll need to put "money on the books" using site code 294103.
- Verify the housing location: Before you drive to San Bruno, double-check they haven't been moved back to 7th Street for a court date.
- Contact the Public Defender: If they don't have a private lawyer, the SF Public Defender’s Office is at 555 7th Street—right across from the jail.
Getting through the system is slow. It’s frustrating. But knowing which building you’re dealing with is half the battle.
