Riverside County Inmate Population Overview
The Riverside County inmate population is spread across a large sheriff jail system and several state-prison facilities located within the county. The Riverside County Sheriff's Office, led by Sheriff Chad Bianco in the inspected official sheriff biography, operates five active adult county jail facilities: Robert Presley Detention Center, Larry D. Smith Correctional Facility, Cois M. Byrd Detention Center, John J. Benoit Detention Center, and Blythe Jail. Those facilities hold adult county jail inmates, including many people awaiting court action and some short-sentence or local-custody inmates.
State-prison custody is a different population. California Rehabilitation Center in Norco, Ironwood State Prison in Blythe, Bautista Conservation Camp #36 in Hemet, and Norco Conservation Camp #0 are CDCR or CDCR/CAL FIRE facilities. A person arrested in Riverside County may begin in a sheriff jail and later move to CDCR if convicted and sentenced to state prison. BOP and ICE custody use separate national systems, and no official BOP prison or ICE detention facility was found physically in Riverside County.
Riverside County Inmate Population Statistics
Official and high-authority sources give enough data to separate county jail population from broader incarceration numbers. BSCC reported Riverside jail average daily population of 3,802 in 2023, using January through September data in its jail population trends report. BSCC's 2022 rated-capacity list gives a combined listed rated capacity of 4,975 for the five active Riverside sheriff jail facilities. Vera identified Riverside as having the fourth highest county jail population in California in 2022.
| Measure | Figure | Source / Date |
|---|---|---|
| Riverside jail ADP | 3,802 | BSCC jail population trends, 2023 Jan-Sept data |
| Total listed jail rated capacity | 4,975 | BSCC rated-capacity list, July 15, 2022 |
| County jail population rank | 4th highest in California | Vera, 2022 |
| State prison population from Riverside County | 7,607 on average day | Vera, 2022 |

Riverside County Inmate Population Trends
BSCC trend data shows the Riverside County jail population fell from 2019 to 2020, stayed level in 2021, then rose in 2022 and 2023. The non-sentenced share also grew. In 2019, BSCC listed 73 percent non-sentenced. By 2022 that share was 89 percent, then 86 percent in 2023. That means the Riverside County inmate population in sheriff jails is heavily shaped by pretrial custody, bail and release decisions, warrants, court timing, and case processing.
| Year | Average Daily Population | Sentenced / Non-Sentenced |
|---|---|---|
| 2019 | 3,772 | 1,010 sentenced / 2,761 non-sentenced |
| 2020 | 3,500 | 730 sentenced / 2,770 non-sentenced |
| 2021 | 3,500 | 560 sentenced / 2,940 non-sentenced |
| 2022 | 3,653 | 393 sentenced / 3,260 non-sentenced |
| 2023 | 3,802 | 520 sentenced / 3,281 non-sentenced |
Riverside County Jail Capacity
The countywide 2023 average daily population of 3,802 was below the combined BSCC listed rated capacity of 4,975, but that does not mean each facility has no pressure. Classification, medical need, gender housing, mental-health care, court location, program placement, and regional booking patterns can make one facility tight even when the countywide number is below total capacity. RPDC is described in sheriff material as the busiest booking facility and a jail that houses many inmates needing specialized handling and care.
| Facility | BSCC 2022 Rated Capacity | Role |
|---|---|---|
| Robert Presley Detention Center | 760 | Downtown Riverside primary county-seat jail and busy booking facility. |
| Larry D. Smith Correctional Facility | 1,458 | Largest and most program-heavy sheriff facility. |
| Cois M. Byrd Detention Center | 1,142 | Southwest county booking and detention facility. |
| John J. Benoit Detention Center | 1,536 | Coachella Valley county jail facility. |
| Blythe Jail | 79 | Palo Verde Valley and Colorado River side local jail. |
Riverside County Inmate Population Laws
California law explains why some Riverside County inmate population and arrest information is public while other records remain restricted. The California Public Records Act names the public-records framework. Law-enforcement arrest-information law makes specified arrest facts public unless disclosure would endanger safety or an investigation. Penal Code 6030 requires BSCC to establish and review minimum standards for local correctional facilities, which supports statewide jail oversight and reporting.
Key Statutes:
Government Code 7920.000 names Division 10 as the California Public Records Act.
Government Code 7923.610 covers public arrest information such as name, physical description, arrest and booking time, charges, bail, and holds, subject to limits.
Penal Code 6030 requires BSCC standards for local correctional facilities.
Penal Code 10008 requires specified public posting when a person dies in custody.
Riverside County State Prison Population
Vera reported 7,607 people from Riverside County in state prison on an average day in 2022. That figure is separate from the county jail average daily population. People in state prison are not searched through the Riverside Sheriff jail roster. They are searched through CDCR CIRIS, the statewide incarcerated-person locator. CDCR also provides a facility locator, visitation information, and money-sending rules that are separate from county jail mail and commissary rules.
Riverside County has active CDCR facilities and camps. Ironwood State Prison reports about 3,300 incarcerated people. Bautista Conservation Camp #36 has a maximum capacity of 120. California Rehabilitation Center remains listed by CDCR, but CDCR announced on August 4, 2025, that CRC will close by fall 2026 with no early releases. Chuckawalla Valley State Prison in Blythe was deactivated in November 2024 and should not be treated as an active facility page.
Search the Riverside County Inmate Population
A Riverside County inmate population search starts with custody type. Use JIMS for Riverside Sheriff jail custody. Use Riverside Superior Court records for charges filed after arrest. Use CDCR CIRIS for sentenced state-prison custody. Use BOP for federal sentenced custody. Use ICE ODLS for immigration detention. VINELink California can support custody or release notifications, but it is not a mugshot or formal charge source.
- Search JIMS by last name for sheriff jail custody.
- Use first name, date of birth, and Gender = Any to narrow or broaden results.
- Open the booking-number link and note current facility and court date.
- Call the facility when a recent booking does not appear or the custody status is urgent.
- Move to court, CDCR, BOP, ICE, or VINELink when the person is outside sheriff jail custody.
Riverside County Inmate Lookup Fields
JIMS has a small set of visible search fields. The last name field is mandatory. First name and date of birth are optional. Gender is a dropdown with Male, Female, and Any, with Male shown as the default during inspection. The results table can include both in-custody and non-current records, using Incustody values Y and N.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Last Name | Text | Yes | Mandatory, maxlength 30. |
| First Name | Text | No | Optional narrowing field. |
| Date of Birth | Text | No | Example format 10/25/1980. |
| Gender | Dropdown | Unspecified | Male, Female, Any. |
| Results | Table | n/a | Booking No., Name, D.O.B., Sex, Incustody. |
Riverside County Inmate Record Fields
A Riverside County inmate record in JIMS can be enough for basic custody routing, but it does not replace a court case search. The inspected profiles showed identity, arrest, booking, facility, and next-court fields. They did not show mugshots, charges, bail, housing unit, case links, release date, or detainers. For booking photos, use the records-request route described on the jail mugshots page. For filed charges, use Riverside Superior Court.
| Field | What It Shows |
|---|---|
| Booking Number | Riverside jail booking identifier. |
| Name and descriptors | Name, sex, race, date of birth, age, hair, eyes, height, and weight. |
| Arrest information | Arrest date and time, arresting agency, and arresting location. |
| Booking information | Booked date and time. |
| Current Facility | Where the person is held or last shown in sheriff custody. |
| Next Court Date | Upcoming court date and time when populated. |
County Jail State Prison Federal ICE
Riverside County inmate population searches often fail when the wrong custody system is used. Sheriff jail custody is local and pretrial-heavy. CDCR custody is for sentenced state-prison commitments. BOP custody is federal sentenced custody. ICE ODLS is for immigration detention. Riverside federal cases are in the U.S. Attorney's Central District of California, but federal prosecution does not mean the person appears in JIMS.
| Custody Type | Who Is Covered | Where to Search |
|---|---|---|
| County jail | Pretrial and local-custody Riverside Sheriff inmates. | JIMS |
| State prison | Sentenced California prison inmates. | CDCR CIRIS |
| Federal prison | Federal sentenced custody. | BOP inmate locator |
| Immigration detention | ICE detainees. | ICE ODLS |
| Notifications | Custody or release alerts. | VINELink California |
Riverside County Custody Access Channels
The fallback chain for the Riverside County inmate population starts with JIMS, then moves to facility phones, Sheriff ISB, GovQA, and in-person records routing when the online result is missing or incomplete. Facility phones are the fastest route for current-custody questions at Robert Presley, Larry D. Smith, Cois M. Byrd, John J. Benoit, or Blythe. Sheriff ISB Records at 951-955-2440 and the Sheriff Public Records Center handle records routing. ISB's lobby is listed at 4095 Lemon Street, 5th Floor, Riverside, CA 92501, Monday through Friday, 8 a.m. to 5 p.m. The Riverside Sheriff's Office app advertises tips, public-safety news, and FAQs, but inspected listings did not advertise an inmate roster, warrant search, booking lookup, or mugshot lookup.

Riverside County Record Boundaries
The Riverside County inmate population leaves several record trails, but each office answers a different question. JIMS is the custody and booking-number route. It can show the current facility and next court date, yet the inspected public profiles did not show charge text, bond amounts, booking photos, housing units, or release projections. Riverside Superior Court public access is the source for formal court records after a jail arrest, including the register of actions and filed documents when public access rules allow them. The District Attorney's process material explains why the arrest charge can change after review, filing, amendment, reduction, dismissal, or sentencing.
Sheriff records requests use the Information Services Bureau or the GovQA Public Records Center. The research file also notes CPRA email routing at cpra@riversidesheriff.org and written CPRA routing to the sheriff's CPRA Unit at 4095 Lemon Street, 5th Floor, Riverside, CA 92501. Police reports are not always released through a simple CPRA request and may be routed to the local sheriff patrol station. Full local summary criminal history is restricted by Penal Code 13300, so a public jail lookup should not be treated as a complete background report.
- Booking record
- The jail intake record that can show booking number, arrest timing, descriptors, current facility, and court date.
- Court record
- The case file created after charges are filed in Riverside Superior Court.
- Custody notification
- A release or custody-status alert path, such as VINELink, not a replacement for the official roster or court portal.

Riverside County Inmate Population FAQ
How big is the Riverside County inmate population?
BSCC reported Riverside jail average daily population of 3,802 in 2023, based on January through September data. That is the sheriff jail population, not the full state-prison population from Riverside County. Vera reported 7,607 people from Riverside County in state prison on an average day in 2022.
How do I search the Riverside County inmate population?
Use JIMS first for sheriff jail custody. Search by last name, add first name and date of birth if known, and set Gender to Any when unsure. If the person is sentenced to prison, use CDCR CIRIS. If federal or immigration custody is involved, use BOP or ICE ODLS.
Does JIMS show Riverside County mugshots?
The inspected JIMS public profiles did not show mugshots. They did show booking number, identity fields, arrest and booking dates, current facility, and next court date. Booking-photo requests should use the sheriff's GovQA Public Records Center when a photo is needed for a records purpose.
Are court charges on the jail roster?
Not in the inspected JIMS profiles. Formal charges and case activity should be checked through Riverside Superior Court public access after the prosecutor files the case. A booking record and a court case are related, but they are not the same record.
