10 Worst Jails In California

Updated August 2026. Every facility on this list is an actual county jail, ranked from the documented record: state audits, federal court orders, grand jury reports, death data, and the words of people who lived it.

Quick answer: By the weight of the public record, the worst jail in California is Men’s Central Jail in downtown Los Angeles, the 1963-era anchor of the deadliest jail system in the state, a system California’s Attorney General sued in 2025 over conditions his office called inhumane. It is followed closely by San Diego Central Jail, the deadliest large-county jail system in California by death rate, and Santa Rita Jail in Alameda County. One important correction up front: San Quentin, Pelican Bay, and Folsom are not jails. They are state prisons, a different system entirely. This list covers real county jails, which hold people awaiting trial, serving sentences, or detained on other legal grounds; bail eligibility depends on the individual case and custody order.

The Worst Jails in California at a Glance

Short on time? This table is the whole article in miniature. Each facility is covered in depth further down.

Three numbers explain why this list exists. California jails recorded 215 deaths in 2022, the deadliest year on record, even though jail populations were smaller than before the pandemic (CalMatters). More than 79 percent of the people held in California jails have not been sentenced for the charge they are held on; most are legally presumed innocent (PPIC, January 2026). And the suicide rate in American jails runs nearly double the rate in state prisons (Bureau of Justice Statistics). Jails are where the system is failing fastest, and they are exactly where someone sits while a family decides what to do about bail.

Jail vs. Prison: The Difference Most Lists Get Wrong

Search “worst jails in California” and most of what comes back is actually about prisons: San Quentin, Pelican Bay, Folsom. Those are famous, and they are not jails. The two systems hold different people, answer to different governments, and matter differently to a family in crisis.

A jail is local. County jails in California are run by county sheriffs under state law (Government Code section 26605) and inspected by the state’s Board of State and Community Corrections. Jails hold people who were just arrested, people waiting for trial, and people serving shorter sentences. The federal Bureau of Justice Statistics defines jails as local facilities that confine people before or after adjudication, usually for sentences of a year or less.

A prison is state. California’s prisons are run by the California Department of Corrections and Rehabilitation (CDCR), which operates more than 30 institutions holding people convicted of felonies and sentenced to longer terms. That roster is where San Quentin (now called San Quentin Rehabilitation Center), Pelican Bay, Folsom, Kern Valley, and CSP Solano belong.

Population sources: PPIC for jails; CDCR weekly population report for prisons.

Two wrinkles make the line blurrier than it used to be. First, California’s 2011 Public Safety Realignment (AB 109) moved certain lower-level felony sentences from state prison into county jail under Penal Code 1170(h), so some people now serve multi-year felony terms in facilities designed for short stays (Judicial Council overview). Second, jails churn: nationally there are about 7.6 million jail admissions a year, against a much smaller, more stable prison population (BJS). That churn is why jail conditions touch far more California families than prison conditions ever will.

For families, the practical step is to identify why the person is in custody. County jails hold people awaiting trial, serving sentences, and facing warrants or supervision proceedings, sometimes on more than one case. Bail may be available on an eligible charge, but posting it does not resolve a separate lawful custody basis. We cover that in more detail in our guide to the difference between jail and prison.

How We Ranked These Jails

“Worst” is a strong word, so this list leans on documents, not vibes. We weighed five kinds of evidence: in-custody deaths and death rates, drawing on the California State Auditor, county disclosures required by AB 2761, and academic trackers like the UCLA Law Behind Bars Data Project; federal and state intervention, meaning U.S. Department of Justice findings, California Attorney General investigations and lawsuits, and active consent decrees; civil grand jury findings from the counties themselves; settlement dollars paid to families; and the testimony of people who were held inside, taken from sworn court declarations, journalism, and public forums, quoted with attribution.

Rankings reflect the record through August 2026. Conditions change, sheriffs dispute findings, and several counties on this list have made real improvements, which we note where they exist. A facility’s placement describes documented outcomes, not the character of any individual officer or deputy working there.

The 10 Worst County Jails in California: The Deep Dive

1. Men’s Central Jail (Los Angeles County)

Quick facts: 441 Bauchet Street, downtown Los Angeles. Run by the LA County Sheriff’s Department. Opened 1963. Roughly 4,000 people held as of July 2026, inside the largest jail system in the United States.

No California jail carries a heavier file. The LA County jails have been under federal court oversight for decades, including a 1996 Department of Justice investigation that became a 2015 settlement over mental health care and suicide prevention that the county still had not fully satisfied years later, plus the long-running Rosas use-of-force consent decree. In 2022, conditions in the system’s Inmate Reception Center became a national story when the ACLU documented people with serious mental illness chained to chairs for days and sleeping on concrete floors, producing a federal injunction and a 2023 settlement. Then the state itself ran out of patience: in September 2025, Attorney General Rob Bonta sued LA County and the Sheriff’s Department, describing cells with broken and overflowing toilets, rat and roach infestations, and no clean water.

The death toll explains the urgency. The Vera Institute counted 147 deaths in LA County jail custody from the start of 2023 through late July 2026, and 62 percent of the people who died were being held pretrial. In 2025 alone, 46 people died, nearly one per week, and Men’s Central Jail accounted for roughly one in four of the system’s deaths from 2023 through 2025. A 2026 UCLA study in PLOS One tied the rising deaths to ever-longer stays in custody.

In their words: A county oversight inspector described vents covered in a foot of black mold on one row and called it some of the worst conditions she had ever seen. Loyola law professor Eric Miller put it flatly in April 2026: “Men’s Central Jail is horrific. It is not fit for human habitation.”

Where it stands now: The Board of Supervisors voted to close Men’s Central Jail back in 2020. In July 2026, the county’s own closure team reported that full closure is not feasible within five years, meaning the building will likely outlast every promise made about it.

2. San Diego Central Jail (San Diego County)

Quick facts: 1173 Front Street in downtown San Diego. The San Diego County Sheriff’s Office operates this primary male intake jail. Its BSCC-rated capacity is 946, according to the Sheriff’s 2023 facility plan; physical and operational bed counts are different measures.

The California State Auditor counted 185 deaths across the San Diego County jail system from 2006 through 2020 and found the highest population-adjusted death rate among the 15 large county systems it compared. That was a countywide result, not a count for this building alone.

An outside study commissioned by the county’s Citizens’ Law Enforcement Review Board listed San Diego Central Jail as the facility for 91 of 179 deaths across seven county detention facilities from December 2011 through April 2024, including 12 of 15 deaths classified as homicide. That medical category includes interpersonal violence and deaths attributed to neglect; it is not a criminal verdict. Among 173 decedents with known legal status across the county system, 147 were unsentenced. Neither figure establishes why each person was held or whether bail was available.

The jail’s heavy intake and specialized medical role complicate simple comparisons, while individual court and oversight records document serious breakdowns in care, housing, observation, and emergency response. The Dunsmore disability settlement and mental-health settlement received final court approval. A separate medical and dental agreement had only preliminary approval as of September 25, 2026, with a final hearing scheduled for November 19.

Where it stands now: The Sheriff’s Office reported a 65 percent drop in overdoses across the county jail system from 2024 to 2025. That statement does not supply an SDCJ-only count or establish which intervention produced the change. Sheriff announcements identify at least five SDCJ-associated deaths in 2026 through September 5, including Daniel Patrick Murphy. Their known or pending causes differ.

3. Santa Rita Jail (Alameda County)

Quick facts: Dublin, in the East Bay. Run by the Alameda County Sheriff’s Office. Opened 1989. One of the largest jails in the country.

In a June 9, 2026 report, KTVU put its tally of deaths linked to custody since 2014 at 78. Its named-person tracker includes deaths at other Alameda facilities, hospitals, and after disputed release; this is a dated media tally, not an official current count of deaths inside Santa Rita. A 2019 KQED investigation flagged it as one of the deadliest large jails in California; three years later the county’s own civil grand jury found feces smeared on the walls of cells listed as ready for occupancy and called for urgent attention to health and safety risks. Since February 2022 the jail has operated under the Babu consent decree, a federal settlement requiring real mental health care, limits on safety-cell confinement, and minimum out-of-cell hours, with the U.S. Department of Justice holding access rights.

Maurice Monk’s November 2021 death led to civil litigation and a criminal prosecution. A May 23, 2025 federal order recounts the family’s allegation that he lay face down for three days as unopened meals, water, and medication accumulated, and records a $7 million county settlement plus separate Wellpath-side agreements. The district attorney announced indictments against three deputies in December 2025, but its July 24, 2026 statement reported that the court dismissed the dependent-adult-abuse counts. The DA said one records-related count remained as of that date. The settlements were not liability verdicts, and the dismissal was not a finding that care was adequate.

In their words: The Monk family’s attorney said staff “did nothing more than stare at him and throw food and medications into his cell like he was an animal in a pen at the zoo.” Community reviews strike the same note in smaller ways: one Yelp reviewer, republished by NBC Bay Area, described the holding cells as “freezing and squalid.”

Where it stands now: The county oversight portal records approval of a first reading of the proposed Sheriff’s Oversight Board and Inspector General ordinance on September 17, 2024 and identifies consultation with affected unions as the next step before adoption. When checked September 25, 2026, the portal still displayed those steps; it did not document an operational board. The website alone does not establish whether every later action has been posted.

4. Robert Presley Detention Center (Riverside County)

Quick facts: Downtown Riverside. Run by the Riverside County Sheriff’s Office, alongside the Cois M. Byrd Detention Center (Murrieta), the John J. Benoit Detention Center (Indio), and the Larry D. Smith Correctional Facility (Banning).

Riverside County’s jails earned their place the hard way: 18 to 19 people died in custody in 2022, the county’s deadliest year on record, with overdoses, suicides, and homicides all represented. Those reported deaths were across the county jail system, not an RPDC-only total. The pattern was alarming enough that in February 2023, Attorney General Bonta opened a formal civil rights investigation into the Sheriff’s Office, citing in-custody deaths and conditions of confinement. As of August 2026 that investigation remains open, with no public findings.

Separately, a 2025 Grand Jury finding and Sheriff response identified an admitted failure by RPDC’s business office to update booking identity information. The homicide examined in that review occurred at SITE-B, not RPDC. The Sheriff reported changes to identity verification, housing decisions, and booking-error tracking.

The county has also paid: a $7.5 million settlement went to the family of Christopher Zumwalt, who was left in a Smith Correctional Facility cell to sleep off a drug crisis and died after a violent cell extraction, without ever receiving a medical evaluation. Sheriff Chad Bianco, asked about jail homicides, told reporters the person who committed the killing “is responsible, not the deputies or the Sheriff’s Office.”

In their words: “We still don’t know the cause of his death and we already buried him. I’m angry, I’m mad,” Becky Shorty, whose son Abel Chacon died in the Byrd Detention Center, told The Desert Sun during the record 2022 wave.

Where it stands now: Deaths have continued across the system, including a death at the Banning facility in late 2025 and a choking death there in April 2026, while the state investigation grinds on.

5. Sacramento County Main Jail (Sacramento County)

Quick facts: Downtown Sacramento. Run by the Sacramento County Sheriff’s Office. BSCC reported a June 2026 average daily population of 1,558 at Main Jail and 1,404 at Rio Cosumnes Correctional Center, or 2,962 countywide. These are monthly averages, not live headcounts. Separately, BSCC listed Main Jail’s rated capacity as 2,296 on July 28, 2026.

The Main Jail has spent the 2020s under a federal consent decree, Mays v. County of Sacramento, approved in January 2020 and covering medical care, mental health treatment, suicide prevention, solitary confinement, and disability access. Progress has been slow enough that by late 2023 the county had reached substantial compliance with only about a third of the decree’s medical provisions, in a facility where 63 percent of detainees have a mental health diagnosis. A court-appointed suicide-prevention expert’s February 2026 report found that no patients on suicide precautions occupied the identified corner blind-spot cells during the October 2025 inspection. The same review still found repeated late observation checks in five Main Jail patient records, with a longest gap of 36 minutes.

The human record matches the paper one. At least 28 people died in Sacramento County jail custody from the start of 2021 through mid-2024, including three deaths in five weeks in 2024, one of them a man who collapsed during booking. In the Main Jail’s inpatient psychiatric unit, Bryan Debbs was killed by his cellmate in an attack that went on for roughly 20 minutes; his family’s lawsuits settled for $1.2 million.

In their words: The legal director of the Prison Law Office, which monitors the jail under the decree, called it “a horrific, dangerous, depressing, awful, filthy place.”

Where it stands now: An updated consent decree was approved in December 2025, court experts are still filing compliance reports into 2026, and community members rallied outside the Main Jail in June 2026 over continuing custody deaths.

6. Fresno County Jail (Fresno County)

Quick facts: Downtown Fresno. Run by the Fresno County Sheriff’s Office. The complex includes Main Jail, North Annex, and West Annex. The Sheriff’s February 2026 visiting page says South Annex permanently closed on December 14, 2024 and was replaced by West Annex. The California State Auditor reported more than 3,000 people on an average day in 2019 across Fresno’s jails. That historical systemwide figure is not a current census.

Fresno shows what happened when California’s 2011 realignment pushed longer felony sentences into a jail never built for them. A ProPublica and Sacramento Bee investigation found 47 people died in the jail in the seven years after realignment, double the 23 deaths of the seven years before, with 11 deaths in 2018 alone. The same investigation counted four inmate-on-inmate killings in seven years; Orange County, with twice the jail population, had one. The jail has been under the Hall v. County of Fresno consent decree since 2015, covering medical care, mental health care, and disability access.

A decade later, that fight is livelier than ever. In June 2026 the county, having spent over $300 million, asked to end the consent decree. Plaintiffs’ attorneys, who had filed a formal notice of noncompliance weeks earlier, answered in August 2026 with a motion to enforce the decree’s medical provisions, citing years of inadequate medical care. Meanwhile the Sheriff’s Office’s own in-custody death disclosures list eight deaths in 2026 through August 1, already matching the county’s deadliest calendar year since it began posting public disclosures in 2023.

In their words: Before Andre Erkins died of untreated heart disease during a four-week sentence, his cellmate says he warned an officer: “This guy needs medical attention ASAP. He’s gonna die!”

Where it stands now: The enforcement motion is pending in federal court as of August 2026, with the county and plaintiffs headed in opposite directions over whether the jail has been fixed at all.

7. West Valley Detention Center (San Bernardino County)

Quick facts: Rancho Cucamonga. Run by the San Bernardino County Sheriff’s Department. The county’s largest jail, with 3,347 beds of capacity described by the Sheriff when checked September 25, 2026. Capacity is not a dated count of people currently held there.

West Valley entered the national conversation in 2014, when federal lawsuits alleged deputies had tortured detainees with stun guns to the genitals and twisted handcuffed wrists, a practice detainees called “chicken-winging.” The FBI opened a civil rights investigation, and in 2017 the county paid a $2.5 million settlement to 32 current and former detainees. Systemwide medical and mental health care then went under the Turner consent decree in 2018.

The deaths have not slowed the way the litigation has. San Bernardino County logged 12 in-custody deaths in 2023, including four in December alone, three of them at West Valley. By November 2024, six of the county’s seven custody deaths that year had happened at West Valley, drawing family protests outside the jail. CalMatters has counted San Bernardino among the deadliest jail systems in the state, and the county sits in an Inland Empire corridor that produced roughly 19 percent of California’s in-custody deaths from 2011 to 2022 despite holding 12 percent of its population (CalMatters).

In their words: “I just want justice for him and all those to be held accountable,” Cindy Hernandez, whose son died at West Valley, said at a protest outside the jail.

Where it stands now: The county was partially released from court monitoring in 2024 after meeting medical benchmarks, even as new deaths and settlements kept arriving.

8. Monterey County Jail (Monterey County)

Quick facts: Salinas. Run by the Monterey County Sheriff’s Office, with medical care contracted to Wellpath. Around 900 people held.

Monterey makes this list on a distinction no county wants: its jail healthcare contractor was held in contempt of federal court. The jail has been under the Hernandez v. County of Monterey settlement since 2015. In September 2023, a federal judge found Wellpath out of compliance with 43 separate requirements and warned of sanctions; in October 2024 the court approved fines of $250,000 to $1 million after Wellpath admitted it could not prove substantial compliance and plaintiffs showed its self-audits had overstated its performance (Voices of Monterey Bay). Weeks later, Wellpath filed for bankruptcy, complicating enforcement.

The stakes are not abstract. Local reporting found that at least 11 consecutive deaths through April 2023 involved alleged violations of the settlement, including a man who died after the jail failed to provide his breathing machine.

In their words: “Running a 1,000-person jail without any on-site psychiatric services is dangerous,” the court-appointed monitor, UCSF psychiatrist Dr. Pablo Stewart, warned. “Whatever’s going on in the Monterey County Jail has to stop,” Eric Sand, whose son died there in 2022, told Monterey County Now.

Where it stands now: In March 2026, a man was fatally assaulted inside the jail and three detainees were charged with murder. The settlement, the fines, and the bankruptcy are all still being litigated.

9. Lerdo Pre-Trial Facility (Kern County)

Quick facts: The Lerdo complex sits just north of Bakersfield. Run by the Kern County Sheriff’s Office, which also operates the Lerdo Justice Facility, a downtown Central Receiving Facility, and a jail in Mojave.

Kern County’s 2023 was among the darkest years any California jail system has recorded: 10 in-custody deaths, including six suicides, with at least one death every month and at least one at every KCSO jail. Since 2008, 91 people have died in Kern County custody. When statewide jail deaths hit their record of 215 in 2022, CalMatters named Kern among the handful of counties setting records, and Kern families joined the push that created the state’s new in-custody death review office.

What sets Kern apart from most systems on this list is what it lacks: no federal consent decree, no court-appointed monitors, no state audit. Oversight is thin, which is exactly what local families and advocates have organized to change.

In their words: “I’ve put in numerous requests to talk to mental health… and you don’t get an answer for 2 months, 70 days down the road. Like that’s… like inhumane,” Corey Collins said by phone from the Lerdo Pre-Trial Facility. His wife Vicky told the same reporters: “The system in there is failing.”

Where it stands now: Deaths have continued at the Lerdo facilities into 2025, and Kern’s in-custody death disclosures are now posted publicly under AB 2761.

10. Theo Lacy Facility (Orange County)

Quick facts: The City of Orange. Run by the Orange County Sheriff’s Department, with about 3,100 beds, alongside the Central Jail Complex and Intake Release Center in Santa Ana.

Theo Lacy is where one of the most infamous episodes in American jail history happened. In 2006, John Derek Chamberlain was beaten to death by other detainees over the course of roughly an hour while the deputy assigned to watch the dayroom watched television instead; a grand jury investigation exposed deputies sleeping on shift and using inmate enforcers. The U.S. Department of Justice opened an investigation of the Orange County jails in 2008 and did not close it until 11 years later. In 2022, a separate DOJ investigation found the county had run a jailhouse informant program that systematically violated defendants’ constitutional rights. Add the 2017 federal inspection that found spoiled, foul-smelling food and moldy showers in units holding immigration detainees, and the 2016 escape in which three men cut through steel and rappelled off the roof of the Central Men’s Jail, and the file speaks for itself.

The modern numbers keep it on the list. A January 2026 ACLU of Southern California analysis counted 119 deaths in Orange County jails from 2010 to 2021, found at least half died within a month of booking, and noted the District Attorney faulted the Sheriff’s Department in none of them. The county’s own Office of Independent Review logged 10 custodial deaths in 2024 and 9 in 2025.

In their words: “Sometimes the bread comes moldy or soggy; we are pretty much starving,” an incarcerated man identified as K. reported through a community food survey covered by Voice of OC; the Sheriff’s Department disputed the claims.

Where it stands now: Deaths at the Intake Release Center and Theo Lacy continued through 2025, per the county’s own reporting, while the informant-scandal reforms remain under DOJ agreement.

Our Santa Ana bail bonds office sits in the same city as the Central Jail Complex and serves Theo Lacy as well.

Five More That Nearly Made the List

Santa Clara County Main Jail and Elmwood (San Jose and Milpitas). Three correctional deputies beat mentally ill detainee Michael Tyree to death in the Main Jail in 2015; they were convicted of murder, saw the convictions overturned, and in 2024 pleaded guilty to manslaughter, clearing the way for their release on time served. The county has operated under two consent decrees since 2019, and 2024 brought 10 jail deaths, the most in two decades.

Santa Barbara County Main Jail. Under the Murray settlement, the county banned its windowless “extreme isolation cells” in 2020, but a 2025 grand jury found three in-custody deaths preventable, including a suicide inside an observation cell. The county has now voted to close much of the aging Main Jail, with replacement housing at the Northern Branch Jail projected to open as soon as late 2028. Our Santa Barbara office serves both county facilities.

San Luis Obispo County Jail. Andrew Holland, held in a mental health crisis, died in 2017 after 46 hours strapped in a restraint chair; the county paid $5 million. The U.S. DOJ found the jail’s conditions unconstitutional in 2021 and reached a settlement agreement with the county in January 2025.

Martinez Detention Facility (Contra Costa County). In 2018 this was the deadliest large jail system in the state by rate, with six deaths, and in-custody deaths have recurred since. Our Martinez office sits near the facility.

Tulare County Pre-Trial Facility (Visalia). Tulare set a grim record in 2022 with eight deaths, four of them suicides. It earns a mention here for the opposite reason too: after staggering its welfare checks and verifying breathing on rounds, the county went months without a single death. Jail deaths are not inevitable. They respond to effort.

Why Are California’s Jails So Deadly?

The most important fact about California jail deaths is that they rose while jail populations fell. The state recorded 215 jail deaths in 2022, an all-time high, up from 156 in 2019, even though jails held fewer people than before the pandemic. Something structural is wrong, and the research points at five overlapping causes.

Realignment filled short-stay buildings with long-stay people. After the 2011 realignment law moved lower-level felony sentences into county custody, jail homicides statewide rose 46 percent, and rose 150 percent outside Los Angeles, as facilities designed for quick turnover began holding people for years. Fresno’s post-realignment death spike is the clearest single example.

Most of the people dying were never convicted. More than 79 percent of California’s jail population is unsentenced, and the deaths track that share: 85 percent of those who died in San Diego custody had no conviction in their case, and 62 percent of LA’s dead since 2023 were pretrial. UCLA’s 2026 study of Los Angeles jail deaths found the median person who died had been in custody far longer than the median booking, making length of pretrial stay itself a mortality risk.

Fentanyl changed the math. California jails recorded 43 overdose deaths in 2022, a toll driven by fentanyl, and substance-related deaths in LA jails grew from about 4 percent of deaths in 2008 to about a quarter by 2023 (PLOS One). Counties that attacked the problem directly saw results, most notably San Diego’s overdose push, including physicians at booking, and its 65 percent reduction from 2024 to 2025.

Jails are where suicide risk concentrates. Nationally, the jail suicide rate runs 49 per 100,000, nearly double the state prison rate of 27, and the danger clusters early: about 40 percent of California jail deaths happen within the first week. San Diego’s independent study found half of its overdose and suicide deaths came within roughly the first two weeks in custody.

Oversight is weaker than most people assume. The state’s 2022 audit faulted not just San Diego but the Board of State and Community Corrections for failing to catch deadly patterns. The Legislature responded with SB 519, which created an In-Custody Death Review Division at the state corrections board that began work in July 2024, but as of early 2026 the new division had yet to complete a single review and lacks enforcement power.

For scale, here is the State Auditor’s own comparison of large-county jail death rates across 2006-2020, deaths per 1,000 average daily population (source table):

One more pressure is building: Proposition 36, passed in November 2024, is expected to add roughly 130,000 jail admissions a year, by one advocacy group’s estimate, most of them people held pretrial. As of June 2025, twelve California jail facilities were already over capacity and 25 more were above 90 percent (PPIC).

If Someone You Love Is in One of These Jails

Everything above is the argument for moving quickly. Here is what families can actually do.

Find them first. Every county on this list runs an online inmate locator. Our California inmate locator guide walks through each county’s system, and our guide to finding out if someone is in jail for free covers what to do when you only know a name. For county specifics, see our San Diego, San Bernardino, and Orange County search guides. If you would rather have a person handle it, call Bail Hotline and an agent will run the search with you at no charge.

Understand the clock. The first days in custody are the most dangerous, especially at crowded intake centers. Booking and processing at large urban jails can take many hours before someone is even visible in the locator. Once bail is set, a bond can usually be posted quickly; how long the jail then takes to release someone depends on that facility’s staffing and crowding, which is exactly why it pays to work with people who deal with that jail every day.

Know the release paths. Depending on the charge and county, release may come by citation, by own-recognizance release, through a bail bond, or at arraignment when a judge revisits bail. Our California bail FAQ explains costs, cosigners, and how the process works step by step.

Speak up if you are worried. If you believe someone inside is in medical or mental health danger, call the facility and ask for the watch commander, put concerns in writing, and follow up. Families in every county above have also turned to civil grand juries, county oversight boards, and civil rights attorneys; those documented complaints are a large part of why the record in this article exists. Every California sheriff must now publicly disclose in-custody deaths within ten days under AB 2761.

Get local help. Bail Hotline has worked these exact jails since 2004, with more than 500,000 cases handled and offices placed near the jails they serve, in most cases directly across the street. Agents are available 24/7, payment plans are available, and the first consultation is free. Call (888) 958-1228 or find your nearest location on our offices page.

Frequently Asked Questions

What is the worst jail in California?

By documented evidence, Men’s Central Jail in Los Angeles. It anchors the deadliest jail system in the state, with 147 deaths systemwide since the start of 2023, sits at the center of a 2025 lawsuit by the California Attorney General over conditions in the county’s jails, and has defeated every closure plan since 2020.

Is San Quentin a jail or a prison?

San Quentin is a state prison, not a jail. It is run by the California Department of Corrections and Rehabilitation and was renamed San Quentin Rehabilitation Center in 2023. Jails are county facilities run by sheriffs; prisons hold people already convicted and sentenced to longer terms.

What is the difference between jail and prison?

Jails are local, sheriff-run facilities holding people awaiting trial or serving sentences of about a year or less; prisons are state or federal facilities holding people convicted of felonies with longer sentences (Bureau of Justice Statistics). In California the line blurred after 2011, when realignment moved some multi-year felony terms into county jails. Bail applies in jail, during the pretrial window.

Which California county has the deadliest jails?

It depends on the measure. San Diego County had the highest death rate among large counties from 2006 to 2020 per the State Auditor; Los Angeles has the most total deaths, with 46 in 2025 alone; and Riverside, Kern, San Bernardino, Tulare, and San Diego all set single-year records in 2022 (CalMatters).

How long can you stay in county jail?

Sentenced misdemeanors run up to a year in jail. Under Penal Code 1170(h), certain felony sentences of 16 months, two years, three years, or longer are also served in county jail rather than prison. People held pretrial stay until their case resolves, which can take months or even years, and that pretrial group is now more than 79 percent of California’s jail population (PPIC).

Why are so many people dying in California jails?

Overdoses, suicides, homicides, and medical neglect, concentrated in the first days after booking. Statewide deaths hit a record 215 in 2022 even as jail populations shrank, and researchers point to realignment-era crowding, fentanyl, untreated mental illness, and weak oversight as the drivers.

Is Men’s Central Jail closing?

Not any time soon. LA County supervisors voted to close it in 2020, but in July 2026 the county’s closure team reported that full closure is not feasible within five years. Roughly 4,000 people remain inside.

How many jails are in California?

California counties operate nearly 120 local detention facilities with more than 82,000 beds, overseen by county sheriffs and inspected by the Board of State and Community Corrections. That is separate from CDCR’s roster of state prisons.

How fast can you bail someone out of one of these jails?

Posting the bond is usually the fast part: once the paperwork, signatures, and payment arrangements are in place, an agent can post at the jail quickly, and Bail Hotline keeps dedicated posting agents on call around the clock. The release itself is controlled by the jail, and at crowded facilities like Men’s Central Jail or San Diego Central it can take hours after posting, sometimes longer. Start early, and start with accurate booking information; our bail FAQ covers what you will need.

Why We Publish This

Bail Hotline is a bail bonds company, and it is fair to ask why a bail company would publish a list like this. The answer is that our offices sit across the street from these buildings. Our agents are in their lobbies every day, and our clients’ families live with what happens inside them. Nobody should learn how a county jail works on the worst night of their life. The more clearly families understand which facility they are dealing with, what its record is, and how release works, the faster and safer those nights end.
