San Diego County Inmate Population
The most useful way to read the San Diego County inmate population is by custody system. The San Diego County Sheriff's Office runs seven county detention facilities through its Detention Services Bureau. Those facilities cover most local arrest and pre-arraignment custody, plus people serving local jail sentences or held for court. The Sheriff reported 3,892 average daily care for incarcerated persons in its 2024 By the Numbers report, with 51,905 bookings into custody that year. A later Sheriff statement on October 29, 2025 described an average daily population of approximately 4,400 across seven detention facilities and said nearly 50,000 people receive care in those facilities each year.
The count rises and falls for several reasons. New arrests add people at intake points such as San Diego Central Jail, Las Colinas Detention and Reentry Facility, and Vista Detention Facility. Court release, bail, own-recognizance orders, dismissals, transfers, and sentence completion reduce the county jail count. Sentenced state prisoners leave the Sheriff roster and move to California Department of Corrections and Rehabilitation systems. Federal defendants at Metropolitan Correctional Center San Diego and immigration detainees at Otay Mesa Detention Center are outside the Sheriff count even though they are held within San Diego County.
The San Diego Sheriff jail population page is one official visual source for jail population navigation. The Sheriff's jail population page is distinct from the individual roster search, and it points users toward population reporting rather than a person's profile.
Use the population page for system context, then use the roster or locator tools below when the goal is to find a specific person in custody.
San Diego County Population Statistics
San Diego County jail statistics come from more than one official source, and each source has a different purpose. Sheriff annual reports describe average daily care, annual bookings, and program volume. The Board of State and Community Corrections publishes rated-capacity workbooks and jail profile material for local detention facilities. Facility pages add site-specific capacity or role details. Those numbers should not be forced into one perfect live count because a rated bed count is not the same thing as a daily head count.
| Measure | Figure | Source / Year |
|---|---|---|
| Average daily care | 3,892 incarcerated persons | Sheriff 2024 By the Numbers |
| Bookings into custody | 51,905 | Sheriff 2024 By the Numbers |
| Approximate average daily population | About 4,400 | Sheriff statement, October 29, 2025 |
| Sheriff jail-system rated capacity | 6,133 beds | BSCC rated-capacity workbook updated April 24, 2026 |
| Annual care volume | Nearly 50,000 people | Sheriff statement, October 29, 2025 |
San Diego County Population Trends
Official figures in the research show a long decline from the 2018 jail-system average daily population to the 2023 and 2024 Sheriff annual-report figures, followed by a higher approximate average daily population described in the Sheriff's 2025 statement. The research did not locate a verified cause for each change, so the trend should be read as a sourced timeline, not as proof of one policy effect. Booking volume was slightly higher in 2024 than in 2023, even while average daily care was lower.
| Year | ADP / Population | Notes |
|---|---|---|
| 2018 | 5,621 ADP | Sheriff suicide-prevention assessment material, May 2018 context. |
| 2023 | 3,971 ADP; 50,169 bookings | Sheriff 2023 By the Numbers. |
| 2024 | 3,892 ADP; 51,905 bookings | Sheriff 2024 By the Numbers. |
| 2025 | Approximately 4,400 ADP | Sheriff statement posted October 29, 2025. |
San Diego County Custody Groups
The research did not locate a static official San Diego table for race, age, offense level, or sentenced and non-sentenced counts. It did identify the official structure of the Sheriff's daily population report: facility rows for SDCJ, George Bailey, East Mesa, Las Colinas, South Bay, Vista, Rock Mountain, and total counts by declared gender identity at intake. The BSCC dashboard can filter jail profile data by county, gender, and disposition, but exact San Diego values were not captured in static form during the research pass.
- Male intake: San Diego Central Jail is the primary intake point for incarcerated males.
- Female intake: Las Colinas Detention and Reentry Facility is the primary intake point for incarcerated females.
- North County intake: Vista Detention Facility books male and female arrested people in North County.
- High security: George Bailey and Rock Mountain hold maximum-security county jail populations.
- Reentry and lower classification: East Mesa focuses on work, education, and reentry programming.
San Diego County Jail Capacity
The BSCC rated-capacity workbook updated April 24, 2026 lists 6,133 rated beds across the seven Sheriff detention facilities. Facility-level figures vary by source and date. San Diego Central Jail has a BSCC rated capacity of 940. Las Colinas is listed at 1,216 in the BSCC workbook, while the Sheriff facility page lists 1,280. Vista has several published figures: 851 in the BSCC workbook, 825 on the Sheriff directory page, and 807 current beds in modernization material. Those differences are a reason to cite the source with the figure rather than mixing them.
Recent reform material also belongs in the capacity discussion. Sheriff Kelly Martinez's 2026 modernization materials describe Vista Detention Facility as the oldest of the seven jails, built and expanded in phases in 1978 and 1989, and beyond useful life. Rock Mountain was returned from a federal lease to the Sheriff in 2016, underwent renovations starting in 2019, and opened House 1 in July 2023 for 200 people. In the October 29, 2025 statement, the Sheriff said facilities need infrastructure, technology, camera, and ADA upgrades, while also citing safety and health-care reforms.
San Diego County Population Laws
California law makes basic arrest and custody information public, but it also limits criminal-history release and governs how local jails operate. For San Diego County inmate population work, the key split is simple: a current jail roster record is not a full criminal-history report, and jail population data is not the same thing as a court case file. The Sheriff's public roster, Records and ID Division, San Diego Superior Court, CDCR, BOP, and ICE each control a different slice of the record.
Key Statutes:
California Government Code section 7923.610 requires state and local law enforcement to release specified arrest information unless an investigation or safety exception applies.
California Penal Code section 13300 limits release of local summary criminal history information.
California Penal Code section 6030 requires BSCC minimum standards for local correctional facilities.
BSCC in-custody death reporting tracks death reports sent to state oversight agencies.
San Diego County Prison Population
People sentenced to California state prison are not searched through the Sheriff roster after transfer. The state system is the California Incarcerated Records and Information Search, often called CIRIS. It can search by name or CDCR number and can show name, CDCR number, age, current location, commitment counties, admission date, and parole-related information when available. San Diego County has one state prison in the facility map: Richard J. Donovan Correctional Facility at 480 Alta Road. It is a CDCR facility, not a county jail.
The official CDCR CIRIS search page is a useful separate visual source for state-prison lookups. The CDCR CIRIS locator should be used when a person has left San Diego County jail for state prison custody.
Use the court record to confirm the sentence and the CDCR locator to confirm the current state-prison location.
Search San Diego County Inmates
The current Sheriff jail roster is San Diego Sheriff Who's In Jail. It covers current Sheriff's detention custody and is the first online stop for a person booked into San Diego Central Jail, Las Colinas, Vista, George Bailey, East Mesa, South Bay, or Rock Mountain. The form is free, but the Lookup button stays disabled until the Cloudflare Turnstile human-verification challenge completes. The Sheriff's page also states that maintenance occurs each Wednesday at noon and is normally restored within 30 minutes.
The search form is strict. Both last name and first name fields are marked mandatory with a two-character minimum and a 25-character maximum. If the verification box does not appear, the Sheriff's troubleshooting steps include closing and reopening the browser, refreshing or hard refreshing the page, updating the browser, switching browsers, or using another device.
- Open the Sheriff Who's In Jail search and complete the human-verification box.
- Enter at least two characters in both the last-name and first-name fields.
- Run the lookup and review any matching names, booking numbers, and custody details.
- Call the centralized custody information line at (619) 409-5000 when facility status or release timing matters.
- If the person was sentenced to state prison, search CDCR CIRIS instead of the county roster.
The Sheriff Who's In Jail search form is the relevant manifest image for county roster searches.
The same form also carries notices about legal-use limits, release-date accuracy, and the Chula Vista Police Department jail list.
San Diego County Roster Lookup
A current San Diego County inmate lookup should start with the Sheriff roster when the person is in county custody. If the arrest was made by Chula Vista Police Department and the person is still in city holding, use the Chula Vista current list first, then check the Sheriff roster after transfer. VINE can add release or transfer notices after a person is found, but it is not the source for court charges or a full booking record.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Last Name | Text | Yes | Mandatory two-character minimum; maximum length 25. |
| First Name | Text | Yes | Mandatory two-character minimum; maximum length 25. |
| Turnstile verification | Challenge widget | Yes | Lookup is disabled until human verification completes. |
| Charge Code | Dropdown | No active field | Captured only in commented HTML; do not rely on it as a visible search field. |
San Diego County Past Records
The research did not locate an official roster-retention period for released San Diego County jail records. If a person no longer appears in Who's In Jail, the next path depends on the question. Booking and arrest report copies route through the Sheriff's Records and ID Division, the Sheriff Public Records Center, or the Records Service Request Form. Court charges, court dates, and dispositions route through San Diego Superior Court, not the Sheriff. Local criminal history from the Sheriff is limited to arrests compiled by the Sheriff's Office and does not cover every arrest made by every agency in the county.
Records and ID is at 9621 Ridgehaven Ct., San Diego, CA 92123, with counter hours Monday through Friday, 8:00 a.m. to 4:30 p.m., closed from 12:00 p.m. to 1:00 p.m., weekends, and holidays. The report-copy path lists a $20 copy fee for crime, arrest, or accident reports, with first-copy exceptions for certain victims or representatives. The local criminal-history route lists Booking.Records@sdsheriff.org, a $14 fee, and a processing goal of 3 to 10 business days.
San Diego County Inmate Record Fields
The public detail template for a Sheriff roster profile includes identifiers, booking context, housing, bail, case, and status fields. Some fields may be blank, redacted, or unavailable depending on the case and custody status. The template did not show a confirmed public mugshot field in the indexed text, so booking-photo questions should route to the Sheriff records process rather than assuming the roster displays a photo.
| Field | What It Shows |
|---|---|
| Current as of | Date or timestamp context for the public roster data. |
| Booking Nbr | Sheriff booking number for the custody event. |
| Name and demographics | Last, first, middle name, date of birth, sex, race or ethnicity, and age. |
| Facility and housing | Facility, address, city, area, and housing unit. |
| Bail Status | Bail information, with the Sheriff's warning that bail does not guarantee release if other holds exist. |
| Case / Charge Information | Public case and charge rows, including charge class and reason-on-calendar fields. |
San Diego County Jail or Prison
A jail roster search works only when the person is in the county jail stage. That stage can include arrest intake, pre-arraignment custody, pretrial detention, local sentences, and holds for court. State prison starts after a qualifying sentence and transfer to CDCR. Federal and immigration custody use federal systems. This distinction matters in San Diego County because the same broad area includes Sheriff jails, Richard J. Donovan Correctional Facility, MCC San Diego, and Otay Mesa Detention Center.
| County Jail | State Prison | |
|---|---|---|
| Who Is Held | Pretrial defendants, local jail sentences, and county holds. | Sentenced California prisoners. |
| Run By | San Diego County Sheriff's Office. | California Department of Corrections and Rehabilitation. |
| Where to Look | Sheriff Who's In Jail and custody line. | CDCR CIRIS. |
| Local Facility Example | San Diego Central Jail. | Richard J. Donovan Correctional Facility. |
San Diego County Federal Search
Federal and immigration custody are separate from the San Diego County inmate population reported by the Sheriff. The BOP inmate locator covers federal inmates from 1982 to the present and is updated daily. MCC San Diego is the local BOP facility, with a public JSON population of 606 modified May 28, 2026. The ICE Online Detainee Locator System searches current ICE custody and people in CBP custody more than 48 hours; it does not search records for people under 18. Otay Mesa Detention Center is the local ICE contract detention facility, with 1,142 ICE beds in the California DOJ 2026 immigration detention report.
The BOP locator is the official search page for federal custody.
If BOP has no match and the person may be in immigration detention, use ICE ODLS or contact the proper ICE ERO field office.
San Diego County Detention Facilities
The San Diego County inmate population is spread across county jail, city holding, state prison, federal, and immigration facilities. Otay Mesa is the biggest user-confusion point because Sheriff, CDCR, ICE, and federal or former federal custody sites are near each other but use different operators and locators. Facility names should be checked before calling or visiting.
- San Diego Central Jail - primary male intake, special handling, medical and psychiatric custody.
- Las Colinas Detention and Reentry Facility - primary female intake and reentry facility.
- Vista Detention Facility - North County intake for male and female arrested people.
- George Bailey Detention Facility - large maximum-security Sheriff facility in Otay Mesa.
- East Mesa Reentry Facility - medium-security reentry, work, and education facility.
- South Bay Detention Facility - non-booking court-adjacent facility below the South Bay Regional Justice Center.
- Rock Mountain Detention Facility - renovated maximum-security Sheriff housing in Otay Mesa.
- Chula Vista Police Department Jail - Type I city holding and booking before Sheriff transfer.
- Richard J. Donovan Correctional Facility - CDCR state prison, searched through CIRIS.
- Metropolitan Correctional Center San Diego - BOP federal detention, searched through BOP.
- Otay Mesa Detention Center - ICE contract immigration detention, searched through ODLS.
