CDCR - San Quentin State Prison (SQ)

San Quentin State Prison — officially renamed the San Quentin Rehabilitation Center in California's recent transformation of the institution — is one of the most historically significant prisons in the United States. It sits on a peninsula in Marin County overlooking San Francisco Bay, and has held people serving sentences from one year to life. In recent years it has become the site of a formal shift toward a rehabilitation-focused, program-heavy mission modeled on Scandinavian correctional systems. For families, that history and evolving mission shape the experience, but the underlying CDCR rules for visitation, mail, and money apply the same as at any California state prison.

About San Quentin and its rehabilitation focus

San Quentin has long been California's most iconic prison, opened in 1852 and holding a range of populations over its history, including the state's men's death row until recent policy changes. In the current era, the institution has become the flagship of CDCR's shift toward a rehabilitation-centered approach: extensive education and vocational programs, one of the country's most active prison journalism and media programs, and a formal move toward the model that inspired the state's "California Model" reforms. For an incarcerated person at San Quentin, that means unusually rich access to programming; for families, it means encouraging your loved one to engage with what is available is one of the most valuable forms of support you can offer.

Every incarcerated person at San Quentin is identified by a CDCR number that stays with them across the whole state system, and you'll need it for visits, mail, and deposits. Because California moves people between institutions as classifications change, confirming that your person is actually at San Quentin before every visit or mailing is essential. Our guide on how to find someone in jail or prison explains how to trace an incarcerated person through California's CIRIS system, and you can search their name directly on AllRecentArrests.us to see their institution and status.

Visitation process and hours

Visiting San Quentin follows the standard CDCR approval pattern with weekend-only hours. Once you have completed and returned CDCR Form 106 (Visitor Questionnaire) and been approved, visitation is Saturdays and Sundays from 7:30 a.m. to 2:30 p.m. Bring only your government-issued photo ID and expect thorough security screening — personal belongings generally cannot be taken into the visitation area, and dress-code rules are enforced strictly. San Quentin's location in Marin County puts it within reach of much of the Bay Area, though weekend traffic on the way to the prison can be significant, so arriving early enough to clear check-in matters.

Because the visiting rooms have their own layout and rules given the facility's age and design, first-time visitors are often surprised by how procedural the process feels. Our complete prison visitation guide covers approval, dress codes, and what to expect at the checkpoint. Given the rehabilitation focus, San Quentin also runs a variety of program-related family events that approved visitors may be invited to; ask your loved one about program schedules that might coincide with visits. Always confirm the specific current visiting rules with San Quentin before you travel.

Mail: USPS only, and publisher-only for books

San Quentin follows California's specific mail rules with a strict twist on publications. All mail must arrive via the U.S. Postal Service and is examined for contraband; keep letters plain, on white paper with blue or black ink, and address every envelope to the inmate's full name, CDCR number, and housing information. Critically, books, magazines, puzzles, and word searches ordered for an inmate must come directly from the publisher — not from you, a private seller, or a used-book service — because that policy ensures items are new, untampered, and compliant with the facility's regulations.

That publisher-only rule surprises many families, but it is not negotiable: a book you send yourself from your shelf will be rejected. If you want to send reading material, order through a publisher's website or through approved retailers that ship directly from publishers to correctional facilities. Our breakdown of how to send mail to an inmate covers the general address format and common rejection triggers, and legal mail from an attorney or a court is handled separately and more protectively under California rules.

How to send money at San Quentin

CDCR gives families three ways to deposit funds, each with its own trade-off. The Lock Box is a no-fee service with a shorter hold time; you send a money order, personal check, or cashier's check to the CDCR Lock Box address. Electronic Funds Transfer (EFT) is a paid service but the fastest option, with funds posting to the inmate's account within 1 to 3 days. Mailing funds directly to San Quentin at 1 Main Street is fee-free but subjects the deposit to a 30-day hold before the money is available. For most families, the Lock Box or EFT is the practical choice; sending directly to the prison is a last-resort option because of the long hold.

The California-wide rule to plan around is that CDCR is required to garnish 50 percent of any non-exempt deposit toward restitution the person owes, so if your loved one has a restitution obligation, only half of what you send may reach their spendable account. Our overview of how to send money to an inmate compares the deposit options and posting times, and our dedicated JPay guide and Access Corrections guide walk through California's electronic deposit ecosystem.

Phone calls, packages, and staying connected

Phone service at San Quentin lets the incarcerated person place calls to numbers on their approved list, so set up and fund a prepaid account tied to your number. Under the 2026 FCC rate caps, per-minute rates have dropped sharply, and our guide to calling an inmate explains account setup and cost control. California allows packages only through approved vendors, so the way to send goods is to order through an approved vendor or fund the canteen so your loved one can buy for themselves. Our guide to sending a care package to an inmate explains how approved-vendor ordering works, and our explainer on how prison commissary works shows what a funded account buys.

Because San Quentin's rehabilitation focus means many programs your loved one can join, encourage participation and ask about ways families can support the specific programs they're in. Journalism, education, and vocational programs at San Quentin have national reputations, and completing them can matter for both parole review and post-release opportunities.

Legal mail, emergencies, and avoiding scams

Legal or privileged mail from an attorney or a court is handled separately from ordinary correspondence and is generally opened only in the incarcerated person's presence when properly marked, so keep legal documents out of personal letters. For emergencies such as a death, serious illness, or birth in the family, the reliable route is to call the facility and ask how to get an urgent message to the person or their case manager, rather than trying to reach them directly, and keeping the CDCR number handy makes that call go faster. If you are worried about a loved one's medical care, mental health, or safety inside, contact the facility's staff directly, explain the situation clearly, and keep a written record of who you spoke with and when.

Be cautious, too, about where you get information and send money. The CDCR inmate search and the department's named deposit vendors are the authoritative channels, so paying an unfamiliar third-party site to "locate" a person or forward a deposit is a common way families lose money for something the system provides directly. When a rule you read online conflicts with what the facility tells you, trust the facility, and confirm anything important by calling (415) 454-1460 before you act on it.

Staying consistent and preparing for release

Whatever mix of calls, mail, and visits you settle into, consistency matters more than any single grand gesture, and steady support is one of the most valuable things a family can offer someone inside. A predictable call, a plainly addressed letter, and an occasional visit give the person something reliable to count on through a hard stretch, and they keep you informed about how they are doing as the sentence progresses.

As a release date approaches, preparation pays off — lining up identification, housing, and income before the day arrives makes the first weeks home far less chaotic. Our reentry guide for life after prison covers those first steps, our guide to finding work after prison addresses fair-chance hiring, and many returning citizens qualify for help through SNAP, Medicaid, and TANF soon after release. If you are supporting a household through an incarceration, our overview of financial help for families of incarcerated people lists resources that can ease the strain.

San Quentin State Prison has a new official name

This institution is now officially called the San Quentin Rehabilitation Center, abbreviated SQRC. It was previously known as San Quentin State Prison, and you will still see the old name on court paperwork, in older correspondence, and across most directories — including in places where the new name has not caught up. Both refer to the same institution at the same address.

Governor Gavin Newsom unveiled plans in 2023 to transform the institution into a rehabilitation centre, and the name change followed from that programme rather than from any change of location or population.

This site still lists the institution under its former name, as do most directories and a great deal of court paperwork.

Practically, use whichever name the system in front of you expects. The department's own records and inmate locator are the authority on how a person's placement is recorded, and a mismatch in the institution name is not a sign that something is wrong.

Inside San Quentin Rehabilitation Center: how the facility is laid out

San Quentin is California's oldest correctional institution, tracing its origins to 1852 and built in July of that year. The facility occupies about 432 acres and holds people at Level I, II and III.

The institution now operates as a rehabilitation centre offering a range of programmes aimed at reducing recidivism.

Layout matters more than families expect. Which yard or unit someone is assigned to drives their custody level, their program eligibility, and often their visiting schedule — so when you call, having the housing assignment to hand will get you a useful answer faster than the name alone.

How crowded San Quentin Rehabilitation Center is right now

San Quentin Rehabilitation Center was designed to hold 3,084 people. As of July 22, 2026 the agency reported a population of 2,276, which is 73.8% of that design capacity.

Running at or below design capacity does not mean the institution is quiet. Population moves in waves, and intake, medical screening, and visiting slots can all come under pressure in a single week without the headline number changing.

For scale, the same report puts the state's institutions as a whole at 86,006 people against a design capacity of 71,074, or 121.0% — so this facility sits well below the system-wide figure rather than being an outlier.

This figure moves week to week. Treat it as the scale of the place rather than a live count, and confirm anything that affects a visit with the institution directly.

Who runs San Quentin Rehabilitation Center

The senior official on site is Chance Andes, who took the role in December 2024. Naming the warden is not just trivia: correspondence about a serious unresolved problem should be addressed to that post rather than to the institution generally, because a letter to a named office creates a record that a call to a switchboard does not.

The institution's main line is (415) 454-1460. Use it for anything urgent — a medical emergency, a safety concern, confirming whether visiting is running — and ask for the watch commander or the shift supervisor rather than leaving a message with whoever answers.

Education, training, and work at San Quentin Rehabilitation Center

Academic programming at San Quentin Rehabilitation Center includes high school diplomas, face-to-face college coursework and degree programmes through Mount Tamalpais College. Enrolment is rarely immediate — most institutions run waitlists, and assignment depends on custody level, sentence length, and prior testing. If your family member wants a place, the request has to come from them through their assigned counsellor; a call from outside will not add someone to a list.

Vocational and career technical training on site includes carpentry, welding and automotive technology. These carry more weight than general programming, because completion is documented and can matter at a parole or release review as evidence of work done inside.

Visiting San Quentin Rehabilitation Center: the current schedule

San Quentin Rehabilitation Center receives visitors on Friday, Saturday and Sunday, with in-person visits offered for a minimum of two hours, though the exact session length varies by institution and availability.

Two things about that schedule are worth knowing before you drive. Published hours are when the visiting room is open, not when you can arrive — processing closes well before the room does, and arriving inside the last hour often means being turned away. And a published schedule is suspended more often than it is changed: lockdowns, staffing shortages, and medical isolation all cancel visiting at short notice, usually without the website being updated.

Visiting is booked through the department's Visitation Scheduling Application. The booking window opens eight days before the visit and closes five days before it, and the daily request period opens at 6:00 a.m. for northern institutions, 6:30 a.m. for central, and 7:00 a.m. for southern, running to 11:59 p.m. Only people already approved as visitors can book, so the approval application has to be granted before any date can be reserved. Visits can be cancelled at any time for health and safety reasons, and can be ended early if staff see a visitor or a resident showing symptoms of a contagious illness.

Call the institution the morning you travel and ask specifically whether visiting is running on your family member's yard or unit — not whether the prison is open. Those are different questions, and the second one gets a misleadingly reassuring answer.

Your first steps

If someone you love has just arrived at San Quentin, focus first on the essentials: write down their CDCR number, complete the Visitor Questionnaire (Form 106) and get approved so you can visit weekend hours, and set up a Lock Box or EFT deposit knowing California withholds 50 percent for restitution. Remember that books and publications must come directly from publishers, not from you. Encourage your loved one to engage with San Quentin's programs, and rely on CDCR's own tools rather than paid third-party sites.
