California has several ways a person can leave state prison before serving a full sentence. Some run automatically in the background: the California Department of Corrections and Rehabilitation (CDCR) tracks credits that shorten a release date without anyone filing anything. Others require a hearing before the Board of Parole Hearings (BPH), a petition to a sentencing court, or a favorable recommendation from a prosecutor or the CDCR. Which routes are open to any one person depends on the offense of conviction, the sentence type, age at the time of the crime, current age and health, and behavior in custody. The main pathways for early release of prisoners in California are custody credits, Proposition 57 nonviolent parole review, youth offender parole, elderly and medical parole, standard parole suitability hearings for life sentences, and court resentencing under a handful of specific statutes.
Custody Credits That Shorten a Determinate Sentence
For anyone serving a fixed-length (determinate) sentence, credits are the most common way the release date moves earlier. CDCR applies them automatically. The rate depends on the current offense and where the person is housed.
- Nonviolent felony in general population: one day of credit for every day served (50%).
- Violent felony under Penal Code 667.5(c): one day of credit for every two days served (33.3%).
- Nonviolent felony in minimum custody or fire camp: two days of credit for every day served (66.6%). Fire camp assignments serving a violent felony earn at 50% rather than 33.3%.
The dividing line is violent versus nonviolent, not serious versus violent. A serious felony that is not also on the violent list earns credits at the higher nonviolent rate.1California Department of Corrections and Rehabilitation. In-Prison Credit-Earning Opportunities
On top of Good Conduct Credits, people can earn milestone credits by completing approved education, vocational training, or rehabilitation programming. These stack. Serious disciplinary violations, including violence or drug offenses, can cause accumulated credits to be forfeited.2California Department of Corrections and Rehabilitation.

Nonviolent Parole Review Under Proposition 57
Proposition 57, passed by California voters in 2016, is one of the most consequential early release mechanisms in the system. It applies to people serving determinate sentences for nonviolent offenses. Once the person has served the full term of the primary offense, before sentencing enhancements are added, CDCR refers them to the BPH for a parole review that can result in release.3California Department of Corrections and Rehabilitation. Nonviolent Offender Parole Review Process for Determinately-Sentenced Persons
Many long sentences are built from a shorter base term plus stacked enhancements. Proposition 57 makes the person parole-eligible at the end of the base term, potentially years before the sentence would otherwise expire. Eligibility looks at the current offenses. Courts have held that CDCR cannot exclude someone based on prior convictions alone.4California Department of Corrections and Rehabilitation. Proposition 57 Nonviolent Parole Review Litigation
Youth Offender Parole
Anyone whose controlling offense was committed at age 25 or younger gets a special parole hearing under Penal Code 3051, regardless of sentence length. The timing depends on the sentence:
- Determinate sentence: hearing during the 15th year of incarceration.
- Life term under 25 years to life: hearing during the 20th year.
- Life term of 25 years to life or longer: hearing during the 25th year.
- Life without parole for an offense committed under age 18: hearing during the 25th year.
At the hearing, the BPH must give great weight to the diminished culpability of youth, the hallmark features of youth such as impulsivity and susceptibility to peer pressure, and evidence of growth and maturity since the offense.5California Legislative Information. California Code PEN 3051 – Youth Offender Parole
Several groups are excluded: people sentenced under the Three Strikes law, people sentenced under the One Strike sex-offense statute, anyone sentenced to death, and anyone sentenced to life without parole for an offense committed at 18 or older.6California Department of Corrections and Rehabilitation. Youth Offender Parole Hearings
Elderly Parole and Medical Release
Two programs open early parole based on age or physical condition.
Elderly Parole
Under Penal Code 3055, a person is eligible for an elderly parole hearing at age 50 or older after serving at least 20 continuous years on the current sentence. It applies to both determinate and indeterminate sentences. The BPH must give special consideration to whether age and time served have reduced the likelihood of future violence.7California Legislative Information. California Code PEN 3055 – Elderly Parole Program The hearing itself uses the standard suitability framework, so meeting the thresholds does not guarantee release.
Medical Parole
Medical parole is for people who are permanently and significantly incapacitated. The head physician at the institution must find a permanent condition that prevents the person from performing basic daily activities and that requires placement in a licensed community health care facility. The BPH then holds a hearing on community placement.8California Department of Corrections and Rehabilitation. Medical Parole Hearings
Compassionate Release
Penal Code 1172.2 provides a separate compassionate release process for people who are terminally ill, generally when a physician determines a life expectancy of six months or less. Unlike medical parole, this is a court-ordered process rather than a BPH decision.9California Department of Corrections and Rehabilitation. Medical Parole – Board of Parole Hearings
Parole Suitability Hearings for Life Sentences
People serving indeterminate life sentences go through parole suitability hearings. Credits do not drive the outcome. The BPH decides whether the person would pose an unreasonable risk to public safety if released, looking at who the person is now.
Factors favoring release include genuine remorse, insight into the causes of the crime, a strong record of rehabilitative programming, stable social connections, and realistic parole plans. Factors against include the brutality of the crime, a pattern of violent behavior, and ongoing disciplinary problems. California law creates a presumption of suitability unless evidence shows current dangerousness requires continued incarceration.10California Department of Corrections and Rehabilitation.

Governor’s Review of Murder Grants
When the BPH grants parole to someone convicted of murder on an indeterminate sentence, the Governor has 30 days to review. The Governor can let the grant stand, reverse it, or refer the case to the full Board for an en banc vote. This review power applies only to murder convictions; for non-murder offenses, the Governor cannot reverse a grant.11California Legislative Information. California Penal Code 3041.212California Department of Corrections and Rehabilitation. What to Expect After a Parole Suitability Hearing
If Parole Is Denied
After a denial, the next hearing is set 3, 5, 7, 10, or 15 years out, depending on how strongly the evidence pointed away from release.13California Department of Corrections and Rehabilitation. The Parole Hearing Process The person or attorney can file a written petition asking the BPH to advance the next hearing based on a change in circumstances or new information. Subsequent petitions can be filed once every three years.14California Department of Corrections and Rehabilitation. Advancing Parole Consideration Hearing Dates
Resentencing in Court
Everything above releases the person within the framework of the original sentence. Resentencing is different. It goes back to a judge and changes the sentence itself.
Vacating a Murder Conviction Under PC 1172.6
Senate Bill 1437, enacted in 2019, narrowed murder liability in California. Before the change, a person involved in a felony that resulted in death could be convicted of murder without killing anyone, intending a death, or being a major participant. The new law limits murder liability to people who actually killed, aided the killing with intent to kill, or were major participants who acted with reckless indifference to human life.
The change is retroactive. People convicted under the old rules can petition the sentencing court to vacate a murder, attempted murder, or manslaughter conviction and be resentenced on any remaining charges. The petition is filed in the court that imposed the original sentence and served on the district attorney. If the court finds a prima facie case for relief, it issues an order to show cause and holds a hearing, typically within 60 days.15California Legislative Information. California Code PEN 1172.6 – Resentencing
Retroactive Enhancement Removal Under SB 483
The RISE Act (SB 483) made retroactive the repeal of one-year enhancements for prior prison terms and three-year enhancements for prior drug convictions. CDCR identifies people currently serving time that includes these now-invalid enhancements and refers their cases to court, where a judge recalls the sentence and removes the enhancement.16California State Senate. Governor Newsom Signs Bill to Retroactively Repeal Ineffective Sentencing Enhancements
General Recall and Resentencing Under PC 1172.1
Penal Code 1172.1 gives courts broad authority to recall any felony sentence and resentence the person as if never sentenced, so long as the new sentence is no greater than the original. A recommendation can come from the CDCR Secretary, the Board of Parole Hearings, the district attorney, or the Attorney General. A court can also act on its own within 120 days of the original sentencing, or at any time if the applicable sentencing laws have since changed.17California Legislative Information. California Code PEN 1172.1 – Recall and Resentencing
Courts considering recall look at post-conviction factors: disciplinary record, rehabilitation efforts, whether age and time served have reduced the risk of future violence, and whether continued incarceration still serves justice. CDCR’s own referral process gives weight to sustained compliance with institutional rules and long participation in rehabilitative programming.18California Department of Corrections and Rehabilitation. Recall and Resentencing Referral
Release Comes With Parole Supervision
Early release is not freedom without conditions. People released from a California state prison serve a period of parole in the community. Someone who served a determinate sentence faces two years of parole with a discharge review after 12 months; a full year without violations typically triggers discharge at that point. Someone who served a life sentence faces three years of parole with reviews at 12 and 24 months.19California Legislative Information. California Penal Code 3000.01
Standard conditions include reporting to a parole agent within one day of release, submitting to warrantless searches at any time, getting permission before traveling more than 50 miles from home, notifying the parole agent before changing address or jobs, and no weapons (including kitchen knives with blades longer than two inches outside the kitchen). The BPH or a parole agent can add special conditions tied to the offense and history. Violating any condition can result in arrest and a return to custody, even without new criminal charges.20California Department of Corrections and Rehabilitation.
