Looking for a reliable list of California prisons? You're not alone. Every month thousands of people search for this exact information - families trying to locate loved ones, researchers studying the justice system, or attorneys preparing for cases. Yet most resources out there are either outdated or missing critical details. After helping dozens of visitors navigate this maze (and making plenty of my own mistakes along the way), I've compiled everything in one spot.
Let me be blunt: California's prison system is confusing. With facilities constantly reopening, closing, or changing functions, even official sources contradict themselves. Last year I drove three hours to visit a client only to discover the prison had been converted to a firefighter training center six months prior. That frustration is why we need accurate, real-world info.
California Prison System at a Glance
Before diving into the list of California prisons, it helps to understand what you're dealing with. The California Department of Corrections and Rehabilitation (CDCR) oversees 34 state prisons currently operating. But that number keeps shifting - we've seen three closures since 2020 alone. These facilities house about 100,000 incarcerated people across several security levels:
| Security Level | Description | Number of Facilities |
|---|---|---|
| Maximum (Level IV) | High-risk inmates, armed guards, restricted movement | 8 prisons |
| Medium (Level III) | General population with perimeter security | 15 prisons |
| Minimum (Levels I-II) | Dorm-style housing, work programs | 6 prisons |
| Specialized | Medical, psychiatric, women's facilities | 5 prisons |
Fun fact: Despite Hollywood's obsession with Alcatraz, it hasn't been a functional prison since 1963. Today's facilities are scattered across remote areas - Central Valley hosts nearly 40% of them due to cheap land costs. The distance creates real headaches for families; visiting someone at Pelican Bay means a 7-hour drive from San Francisco through mountain passes.
Note: We're only covering state prisons here. If you need county jails (like LA's Twin Towers) or federal facilities (such as Lompoc), that's a different list entirely. Federal prisons follow separate rules and visiting procedures.
Complete List of California Prisons (2024 Operational Facilities)
Bookmark this section - it's the most requested part when people need a list of California prisons. I've verified each entry with CDCR's latest facility status reports as of May 2024. The table includes practical details you won't find elsewhere:
| Prison Name | Location | Type | Capacity | Key Programs | Public Transport Access |
|---|---|---|---|---|---|
| San Quentin State Prison | Marin County | Mixed (Level II-IV) | 3,082 | Firefighter training, media center | Ferry + bus (limited) |
| Pelican Bay State Prison | Crescent City | Maximum (Level IV) | 3,347 | Behavioral programs | None (4hr drive from airport) |
| Corcoran State Prison | Kings County | Maximum/Medium | 4,908 | Vocational farming | Shuttle from Hanford station |
| Folsom State Prison | Sacramento County | Medium (Level III) | 3,260 | Auto repair certification | Light rail + bus |
| California State Prison, Los Angeles | Lancaster | Maximum | 2,200 | Substance abuse treatment | Bus from Lancaster station |
| Valley State Prison | Chowchilla | Women's facility | 2,024 | Parenting programs | Limited shuttle service |
| California Medical Facility | Vacaville | Specialized medical | 2,540 | Chronic care, hospice | Amtrak station nearby |
| Mule Creek State Prison | Ione | Medium | 3,588 | Welding, construction trades | None (rural location) |
Recently Closed Prisons
Don't waste trips like I did! These facilities appear on outdated lists but are inactive:
- Deuel Vocational Institution (Tracy) - Closed 2021, now police training site
- California City Correctional Facility - Shut down 2023 due to structural issues
- Chuckawalla Valley State Prison - Partially closed, only administrative staff remain
Finding Someone in California's Prison System
Locating an inmate is the #1 reason people search for a list of California prisons. The official CDCR inmate locator works... when it works. Last month it was down for 11 days during "system upgrades." Here's what actually works:
First, gather this info: Full legal name, date of birth, and CDCR number if you have it. Without the CDCR number, searches fail about 30% of the time in my experience.
Alternative Search Methods When Systems Fail
- Call the facility directly: Guards often have paper rosters (I got info this way during the last outage)
- County jail records: If recently transferred, origin jails keep manifests
- Victim notification networks: VINE system provides custody status alerts
Remember: Privacy laws restrict information. If someone requests "no info release," even family gets blocked. Happened to my client's wife last spring - took three weeks to resolve through paperwork.
Visiting Rules They Don't Tell You
Official guidelines miss crucial nuances. After visiting 14 facilities over two years, here's what matters:
| Prison | Visiting Hours | Dress Code Pitfalls | Booking Lead Time | Child Rules |
|---|---|---|---|---|
| San Quentin | Sat-Sun 7:30am-2pm | No denim whatsoever | 21 days minimum | Birth cert. + ID for minors |
| Pelican Bay | Fri-Sun 8am-3pm | Gray/white only tops | 30 days required | No kids under 12 |
| Corcoran | Thu-Sun 8am-5pm | No underwire bras | 14 days minimum | Guardian letter notarized |
| Women facilities | 7 days/week | No nail polish | 10 days minimum | Diaper bag inspection |
Pro tip: Always bring physical ID even if you registered online. Tehachapi turned away my colleague because "the system glitched." Cash for vending machines too - cards rarely work inside.
Watch out: Some prisons like Solano have banned all physical contact since 2022, not even handshakes allowed. Others like Folsom permit brief hugs at start/end. Always confirm current rules.
Covid Policy Fallout & Current Restrictions
The pandemic permanently changed access. Vaccination proof ended last year, but these changes stuck:
- Video visits now standard (costs $12.95/session through GTL)
- Outdoor visits eliminated at 80% of facilities
- Photo bans enforced strictly
- Medical co-pays doubled to $5 per request
Frankly, the video system frustrates me. Connection drops constantly, and the 30-minute time limit includes technical troubleshooting. Families deserve better.
Regional Breakdown: Northern vs Southern Prisons
Northern California Prisons
More remote = tougher visits but better rehabilitation programs:
- San Quentin (Marin)
- Folsom (Sacramento)
- Pelican Bay (Del Norte)
- Salinas Valley (Monterey)
Traffic note: Highway 101 to Pelican Bay gets snowed in December-February. Check Caltrans cameras.
Southern California Prisons
Easier access but overcrowding issues per recent audits:
- Calipatria (Imperial)
- Centinela (Imperial)
- Lancaster (Los Angeles)
- Tehachapi (Kern)
Watch for: Summer temperatures exceed 110°F at Imperial Valley facilities. Visit mornings only.
Controversial Facilities Worth Noting
Not all prisons operate equally. Based on DOJ reports and inmate testimonials:
- Pelican Bay Security Housing Unit: 23-hour isolation continues despite reform promises
- Corcoran: Still uses pepper spray more than any facility (2023 data)
- Wasco: Under investigation for inadequate medical care
Meanwhile, Folsom's vocational programs have reduced recidivism by 18% - proof rehabilitation focus works when implemented.
Essential Contact Information
Save these - finding them during crises is impossible:
- CDCR Main Switchboard: (916) 445-6712 (expect 25+ min hold times)
- Inmate Family Council: (800) 344-9160 (advocacy support)
- Ombudsman Complaints: (877) 319-8787 (for rights violations)
- Emergency Lockdown Hotline: (916) 445-4952 (recorded updates)
Personal advice: Email facilities instead of calling. I get responses 60% faster through institutional emails like [email protected]
Common Questions Answered
How many state prisons are in California?
34 operational facilities as of 2024 - down from 37 in 2020 due to budget cuts and declining inmate populations. This excludes private facilities and county jails.
Which California prison houses death row?
San Quentin holds all male condemned inmates. Condemned women go to Central California Women's Facility. Executions have been paused since 2019.
Can I send books to inmates?
Yes, but only directly from publishers. Amazon used to work until 2021 policy changes. Try Bookshop.org or Powell's instead.
What's the oldest operating prison?
San Quentin opened in 1852. Its aging infrastructure causes constant issues - last winter's pipe burst flooded visitation rooms for weeks.
Are there private prisons in California?
Banned since 2020 (AB32). Any "private" listings refer to out-of-state contract facilities holding California overflow inmates.
How do prison work programs operate?
Inmates earn $0.20-$1.45/hour for jobs like laundry, kitchen duty, or firefighting. Top-earning gig: Data entry for Caltrans ($1.45/hr).
Transportation Challenges & Solutions
Getting to remote prisons tests anyone's patience. My worst experience: 5 bus transfers to reach Corcoran only to be denied entry for wearing the wrong socks (seriously). Here's how to avoid disasters:
- Central Valley Facilities: Amtrak San Joaquins line stops near 6 prisons
- Southern Desert Prisons: United Bus Lines from LA Union Station
- Northern Coastal: Zero public transit to Pelican Bay - rent a car
Rideshare groups exist on Facebook ("CA Prison Rides"). I've shared rides twice - verify identities thoroughly before committing.
Changes Coming in 2024-2025
The prison landscape keeps evolving:
- Closures: Chuckawalla shutting fully by Q3 2024
- Conversions: Solano becoming mental health facility
- New Construction: 1,200-bed Stockton complex delayed until 2026
- Tech Updates: Tablet rollout for all inmates (email access, limited internet)
Budget constraints mean more closures loom. Always confirm a facility's status before travelling.
Final thoughts: This list of California prisons reflects today's reality, not bureaucratic paperwork. Facilities change faster than websites update. If something here saved you a wasted trip, share it with someone else navigating the system. And if you spot outdated info? Email me - we'll fix it together.
