It depends on the kind of supervision. People arrested on a probation violation may be eligible for release, and in some cases bail, though a judge often decides. People held on a state parole hold usually can't bail out of that hold at all. People on county postrelease community supervision (PRCS) who are serving a short "flash incarceration" stay until it ends. If there's also a new charge, bail on that charge is a separate question.
Families often use "probation" and "parole" to mean the same thing, but California treats them differently. Ask the jail, the person's officer, or a bail agent which applies:
The jail's inmate lookup may show a code or note such as "hold" or "no bail." Our guide on finding someone in jail in Southern California explains where to look.
Under Penal Code 1203.2, a probation officer or peace officer can rearrest someone on probation without a warrant if they have probable cause to believe a condition was violated. The court can also issue a warrant.
Whether bail is available right after arrest depends on the county. Each county's bail schedule handles probation violations its own way. For example:
If the arrest was on a probation violation warrant, the bail amount (or "no bail") is usually written on the warrant by the judge.
California law gives people arrested on a probation violation a starting presumption in favor of release once they're in front of a judge. Penal Code 1203.25 says that at or after the initial hearing, and before the formal violation hearing, a person should be released on their own recognizance unless the court finds by clear and convincing evidence that conditions are needed to protect the public and make sure they come back to court.
Some key points of that law:
In short: someone may sit in custody until the first court date on a probation violation, and the judge then decides release terms. Whether a bail bond can be used at that stage depends on how the judge sets bail, so ask the defense attorney.
When someone on state parole is arrested or suspected of a violation, a parole agent can place a "parole hold" (sometimes called a 3056 hold, after Penal Code 3056). The San Diego County Sheriff's booking reference, for example, lists a state parole hold under PC 3056 as "Held without bail."
In general, that means a bail bond can't be used to get someone out of a parole hold. Penal Code 3056 does allow a court to order a parolee released after arrest on terms the court finds appropriate (except during flash incarceration), but that's a decision for the judge, not something a family can arrange by posting bail.
If the person was also arrested on a new charge, that charge may have its own bail. Posting bail on the new charge resolves only that charge. The person will usually stay in custody on the parole hold until it's lifted or a judge orders release. Before you pay for a bond in this situation, ask the bail agent to confirm whether the person will actually walk out.
People on postrelease community supervision are supervised by county probation. When they violate a condition, the county can respond with "flash incarceration." Under Penal Code 3454, flash incarceration is a short stay in a city or county jail, from one to 10 consecutive days, meant to address a violation without the disruption of a longer revocation.
Someone serving flash incarceration generally stays until it's over. Penal Code 3455, which lets a court order a supervised person released after arrest, specifically excludes people serving flash incarceration.
For more serious violations, the county can ask the court to revoke or modify PRCS. Under Penal Code 3455, the supervising agency may also decide to keep the person in custody before their first court appearance if it finds they're an unreasonable public safety risk, may not appear, or should be held in the interests of justice. Any custodial sanction for a PRCS violation is capped at 180 days in county jail.
When bail is available and a bond can be used, premiums are typically 10% of the bail amount, based on rates filed with the California Department of Insurance, and payment plans are available. Our page on how bail works covers the basics.
