Custody and Confinement Facilities: Types, Differences & Bail Options

When someone is arrested or detained, understanding where they are being held is an important first step in determining what happens next. Different custody and confinement facilities serve different purposes, from processing recent arrests to housing individuals awaiting trial or serving criminal sentences.

Jails, prisons, processing centers, juvenile detention facilities, and civil detention centers operate under different legal systems and release procedures.

If you or a loved one has been taken into custody in California, understanding these differences can help you locate the person, identify the appropriate authorities, and determine whether bail may be available.

What Are Custody and Confinement Facilities?

Custody and confinement facilities are locations where individuals are held under the authority of law enforcement, correctional agencies, courts, or immigration authorities.

These facilities may serve several purposes, including:

• Processing individuals following an arrest
• Holding defendants awaiting criminal proceedings
• Housing individuals serving criminal sentences
• Providing secure supervision for minors
• Detaining individuals during immigration proceedings
• Managing transfers between correctional facilities

The type of facility depends on the individual's legal status, age, charges, and the agency responsible for their custody.

1. Jails: Local and County Detention Facilities

Jails are generally operated by local governments, county sheriff's departments, or other authorized agencies.

They primarily house individuals who have been arrested and are awaiting trial, sentencing, transfer, or another legal proceeding. They may also hold individuals serving shorter criminal sentences.

Who Is Held in Jail?

Jails may house:

• Individuals recently arrested
• Defendants awaiting arraignment
• People awaiting trial
• Individuals unable to obtain pretrial release
• People serving certain misdemeanor or felony sentences
• Individuals awaiting transfer to another facility

In California, county jails can also house people serving certain felony sentences under the state's criminal justice realignment laws. Therefore, jail confinement is not always limited to sentences of less than one year.

Can Someone Post Bail From Jail?

In many cases, yes.

If a defendant is eligible for release on monetary bail, a licensed bail bond agent may be able to post a bond at the appropriate facility.

However, not every defendant qualifies for monetary bail. Some individuals may be released without paying bail, while others require judicial review or remain detained under a court order.

2. Prisons: State and Federal Correctional Institutions

Prisons are generally designed to house individuals serving longer criminal sentences following a conviction.

They are operated by state correctional departments or the federal government.

State Prisons

California state prisons are operated by the California Department of Corrections and Rehabilitation (CDCR).

These institutions generally house individuals sentenced to state imprisonment for qualifying felony convictions.

Federal Prisons

Federal prisons are operated by the Federal Bureau of Prisons (BOP).

They house individuals serving federal criminal sentences, which may involve offenses such as federal drug trafficking, financial crimes, or other violations of federal law.

Can You Post Bail for Someone in Prison?

Traditional pretrial bail generally does not apply to someone already serving a prison sentence.

However, an individual may have a separate pending criminal case, appeal, or other legal matter that involves different custody and release procedures.

A criminal defense attorney can help determine whether any release options are available.

3. Processing Centers: Where Arrests Are Documented

Processing centers are facilities or designated areas where individuals undergo intake procedures after being arrested or transferred into custody.

Depending on the agency and jurisdiction, processing may occur at a police station, county jail, central booking facility, or specialized detention center.

What Happens at a Processing Center?

Common procedures include:

• Recording personal information
• Fingerprinting
• Taking booking photographs
• Reviewing alleged charges
• Checking criminal history
• Identifying outstanding warrants
• Determining custody or transfer status
• Reviewing initial release eligibility

The purpose is to establish the individual's identity, document the custody event, and determine the appropriate next steps.

How Long Does Processing Take?

There is no universal processing time.

The duration may depend on the facility, staffing, volume of arrests, required background checks, and whether additional review is necessary.

In some cases, individuals may be released after processing. Others may be transferred to another detention facility or remain in custody pending a court appearance.

4. Juvenile Detention Centers: Facilities for Minors

Juvenile detention centers are designed to hold minors involved in the juvenile justice system when secure detention is legally authorized.

Unlike adult correctional facilities, California's juvenile justice system has distinct procedures for detention, supervision, rehabilitation, and court involvement.

Why Are Minors Held in Juvenile Detention?

A minor may be detained because of:

• Allegations involving a criminal offense
• A pending juvenile court hearing
• Court-ordered detention
• Safety or supervision concerns
• Other circumstances authorized under juvenile law

Juvenile facilities may provide educational programs, counseling, and other services while minors remain in custody.

Can Parents Post Bail for a Juvenile?

In California juvenile delinquency proceedings, the traditional adult monetary bail system generally does not apply.

Instead, release decisions are handled through juvenile justice procedures and the juvenile court.

Parents or guardians should contact the appropriate juvenile authorities and a juvenile defense attorney to understand the available options.

5. Civil and Family Residential Detention Centers

Civil detention facilities operate under legal frameworks that differ from the criminal justice system.

Some are used for immigration-related administrative custody, while others may be designed or designated for family groups.

Although immigration detention is generally classified as civil rather than criminal custody, these facilities may still impose significant restrictions on movement.

What Are Immigration Detention Centers?

Immigration detention facilities may hold individuals while federal authorities determine matters involving immigration status, removal proceedings, or other administrative actions.

Depending on the circumstances, a person may be held in:

• A dedicated immigration detention facility
• A contracted detention center
• An authorized local detention facility
• Another facility designated for immigration custody

What Are Family Residential Centers?

Family residential centers are facilities intended to house family groups in immigration custody under applicable federal policies.

These facilities have been the subject of public debate and legal scrutiny regarding conditions, family welfare, and the appropriateness of detention.

Their availability and operating policies can change.

Can Someone Be Released on an Immigration Bond?

Some individuals in immigration custody may qualify for release through an immigration bond or another authorized process.

However, eligibility depends on immigration law, the individual's circumstances, and the authority responsible for the detention.

Immigration bonds are different from traditional criminal bail bonds, and not everyone in immigration detention is eligible for a bond.

Jail vs. Prison vs. Detention Center: What's the Difference?

The main differences involve the purpose of confinement, the responsible agency, and the legal status of the individual.

How to Find Someone Who Has Been Arrested in Los Angeles County

If you are trying to locate a loved one, start by identifying which agency made the arrest.

Depending on the circumstances, the individual may be held at a local police station, a Los Angeles County detention facility, or another institution.

Information that can help includes:

• Full legal name
• Date of birth
• Approximate arrest date
• Arresting agency
• Booking number, if available
• Last known detention location

The Los Angeles County Sheriff's Department provides inmate information resources for people held within its custody system.

If the individual has been transferred to a state prison, federal prison, juvenile facility, or immigration detention center, you may need to contact a different agency.

How Does the Type of Facility Affect Bail?

The location and legal basis for detention can determine whether a traditional bail bond is an option.

County jails: A bail bond may be available when monetary bail has been established and the defendant is eligible for release.

State and federal prisons: Traditional pretrial bail generally does not apply to individuals serving criminal sentences.

Processing centers: Release eligibility may still be under review, or a person may be released directly under applicable procedures.

Juvenile detention centers: Release generally follows juvenile court procedures rather than adult bail requirements.

Immigration detention centers: Eligible individuals may have access to separate immigration bond procedures.

Before arranging a bail bond, it is important to confirm the individual's custody status and whether a bond can legally be posted.

What Happens After Someone Is Released From Custody?

Release does not necessarily mean the legal case has ended.

Depending on the circumstances, individuals may need to:

• Attend scheduled court appearances
• Follow release conditions
• Report to supervising authorities
• Comply with travel restrictions
• Follow protective or restraining orders
• Meet other legal requirements

Failure to comply with applicable release conditions can result in additional legal consequences.
