Stanislaus County Inmate Population Overview
The Stanislaus County inmate population is centered on the Sheriff's Adult Detention Division in Modesto. The official Adult Detention Facilities overview states that the division cares for over 1,400 pre-trial, sentenced, and out-of-custody incarcerated persons at any given time. That wording matters. It is not only a count of people sleeping in beds on one day. It also includes people handled through custody-related alternatives and detention programs. The same sheriff source says the division operates four detention facilities and one court holding facility, with the public facility pages focused on the four mapped detention buildings.
The local custody count changes as people are arrested, booked, released on bail or own recognizance, moved to minimum housing, assigned to REACT, or transferred after sentencing. Sheriff's Detention Center - East is the booking and releasing hub, so many new arrests touch that building before a later facility assignment appears. Once a person is committed to state prison, the lookup path changes to CDCR CIRIS. Federal and immigration custody use still different tools. Keeping those systems separate is the key to reading Stanislaus County inmate population data correctly.
Stanislaus County Inmate Population Statistics
Official Stanislaus County figures should be read by source and measurement type. The sheriff's detention overview gives the broad population statement. Facility pages give capacity or bed figures for each building. Those figures can be added to understand the mapped detention system's scale, but they should not be called a live count. SDC-East says it houses up to 559 individuals. SDC-West and REACT use rated capacity language. Minimum Housing Units 1 and 2 are listed as two 192-bed units.
| Measure | Figure | Source / Date |
|---|---|---|
| Adult Detention Division population | Over 1,400 pre-trial, sentenced, and out-of-custody incarcerated persons | Sheriff Adult Detention Facilities overview, inspected 2026-05-31 |
| SDC-East capacity | Up to 559 individuals | SDC-East facility page, inspected 2026-05-31 |
| SDC-West rated capacity | 510 | SDC-West facility page, inspected 2026-05-31 |
| Minimum Housing Units capacity | 384 total beds | Minimum Housing Units page, inspected 2026-05-31 |
| REACT rated capacity | 288 | REACT facility page, inspected 2026-05-31 |
Note: The 1,741 total is a calculated capacity total from facility pages, while the sheriff's over-1,400 statement is a population description that includes out-of-custody participants.
Stanislaus County Inmate Population Trends
The research file located official BSCC jail population trend and demographic reference PDFs, but exact Stanislaus County rows were not extracted. For that reason, the population trend section should stay conservative. The strongest current local number is the sheriff's over-1,400 statement from the Adult Detention Facilities overview. The strongest facility trend facts are construction and program changes: SDC-West opened in 1992, Minimum Housing Unit 2 opened in 2013 after the Men's Honor Farm history, SDC-East opened in 2017, and REACT opened in 2018 as a program-based facility.
| Period | Published Figure | How to Read It |
|---|---|---|
| 2026 page inspection | Over 1,400 | Current sheriff description of people in Adult Detention Division care. |
| 2011-2023 | Official BSCC source located | Use the BSCC jail population trends PDF for extracted year rows before quoting exact ADP values. |
| 2012-2021 | Official BSCC source located | Use the BSCC Stanislaus demographic reference data for demographic rows before quoting percentages. |
Where Stanislaus County Holds Inmates
The Stanislaus County inmate population is not held in one generic jail building. The public facility map shows a detention campus on East Hackett Road with three mapped facility names at the 200 E. Hackett Road address and REACT next door at 194 E. Hackett Road. Each building has a different role. The roster's facility field helps explain where a person is being held within that shared sheriff system.
- Sheriff's Detention Center - East holds booking and releasing functions, maximum-security housing, medical, mental-health, receiving, and transportation functions.
- Sheriff's Detention Center - West is a direct-observation, pod-style facility for male and female incarcerated persons.
- Minimum Housing Units 1 and 2 hold minimum-security county detainees in two 192-bed units.
- Re-Entry and Enhanced Alternatives to Custody Training (REACT) is the open-dayroom, program-based reentry and alternatives facility.
Stanislaus County Jail Population Laws
California law makes much of the Stanislaus County inmate population record public, but it also leaves room for safety, privacy, and investigation limits. The California Public Records Act is the broad access law. A separate arrest-information statute lists basic arrest and holding-location data that local law enforcement must make public when disclosure does not create a safety or investigation problem. Jail standards and death-in-custody reporting are governed by separate rules.
Key Statutes:
Government Code 7920.000 names the California Public Records Act as the core state public-records law.
Government Code 7923.610 requires public release of specified arrest information, including booking time, bail, charges, warrants, and holding location.
Penal Code 6030 supports BSCC minimum standards for local detention facilities.
Penal Code 10008 requires custodial agencies to post specified information after an in-custody death.
Search the Stanislaus County Inmate Population
The official current-custody lookup is the Stanislaus County Sheriff's Who's in Jail page. It covers the shared county detention system, not just one building. Use it first for a person recently arrested, awaiting court, serving a local sentence, or assigned to SDC-East, SDC-West, Minimum Housing, or REACT. The form presents name, date of birth, and seven-digit booking number as alternate paths. The cleanest search is usually one strong identifier, especially the booking number when known.
- Open the sheriff's Who's in Jail search page.
- Choose name, date of birth, or seven-digit booking number. Do not assume all fields are required.
- Use the facility filter only when the current building is known.
- Open View Full Booking Details to see facility, booking date, release date field, charge rows, bail, case number, and court date.
- If no result appears, retry with a different identifier, call the facility, or check CDCR, BOP, ICE, or VINELink depending on the custody path.
Stanislaus County Roster Search Fields
The Stanislaus County jail roster is useful because its public template exposes both search controls and profile fields. A result-list card can show name, booking number, date of birth, place of birth, booking date, arresting time, and arresting agency. The full booking profile can add the current facility, release date field, charges, case number, bail, and court date. Those details are booking and custody records; formal court records can change after the District Attorney reviews the case.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Name | Text | Unspecified | Use the spelling most likely used at booking. |
| Date of Birth | Date or text | Unspecified | The profile template uses month/day/year formatting. |
| 7 - Digit Booking Number | Text | Unspecified | The most precise county jail identifier and needed for mail. |
| Facility filter | Dropdown | No | Filters All Facilities, SDC-East, SDC-West, Minimum Housing, or REACT when known. |
Stanislaus County Inmate Record Fields
A Stanislaus County inmate record is strongest for current custody and booking detail. The inspected roster text did not show home address, Social Security number, driver's license number, victim information, cell block, or a full physical descriptor set. It did show the fields a family member usually needs for next steps: booking number, facility, charges, case number, bail, and court date. For official documents beyond the roster, use the Sheriff's Records Division or the court.
| Field | What It Shows |
|---|---|
| Booking Number | Seven-digit county booking identifier for search and mail. |
| Facility | Current sheriff facility, such as SDC-East, SDC-West, Minimum Housing, or REACT. |
| Arresting Agency | Agency responsible for the arrest or booking. |
| Charges | Booking charge rows, which may differ from later filed court charges. |
| Bail | Bail amount by charge row when listed, subject to holds and court changes. |
| Court Date | Scheduled court date shown on the booking profile. |
Stanislaus County Jail vs State Prison
The county jail roster and CDCR CIRIS answer different questions. The sheriff roster is for local custody before trial, local sentences, booking/release, minimum housing, and REACT. CDCR CIRIS is for people committed to California state prison after sentencing. A person can leave the Stanislaus County jail roster after transfer, even when the original case began in Stanislaus County Superior Court.
| Lookup Need | County Jail | State Prison |
|---|---|---|
| Who is held | Pre-trial detainees, local sentenced people, and county program custody | People committed to CDCR after state sentencing |
| Run by | Stanislaus County Sheriff's Office | California Department of Corrections and Rehabilitation |
| Identifier | Seven-digit booking number | CDCR number |
| Where to search | Sheriff's Who's in Jail roster | CDCR CIRIS statewide locator |
The CA.gov CIRIS service page says state results can include name, CDCR number, age, current location, commitment counties, admission date, and parole hearing dates or outcomes. Those are prison fields, not Stanislaus County jail fields.
The official CDCR CIRIS search interface is the place to start when a Stanislaus County case has moved into state prison custody.
CIRIS is statewide, so searchers should not expect it to show the local booking number, county jail facility, or Stanislaus jail mail format.
Federal and ICE Inmate Search
No official BOP prison or ICE detention center was located in Stanislaus County. That does not mean a locally arrested person can never have a federal or immigration custody issue. It means the search path changes. Federal sentenced prisoners are searched through the BOP Inmate Locator. Immigration detainees are searched through ICE ODLS. VINELink can help with custody notifications, but it is not a full booking-detail profile like the sheriff roster.
The BOP locator has separate number and name search paths. Number search can use a BOP Register Number, DCDC Number, FBI Number, or INS Number. Name search can include first, middle, last, race, age, and sex. BOP result fields can show name, register number, age, race, sex, release date, and location.
The official Federal Bureau of Prisons locator is a separate national database, not a Stanislaus County jail roster.
A BOP result marked released or not in BOP custody does not rule out another system, such as county jail, state prison, supervision, or immigration custody.
Stanislaus County Records Requests
When a current roster search does not answer the question, the Sheriff's Records Division is the local records path. The research file identifies the Records Division at 250 E. Hackett Road in Modesto with phone (209) 525-7117. Crime and incident reports are requested in person with valid ID and an Application for Release of Information. The official report page lists a fee of $5 for the first four pages and $1 for each added page. Release limits can apply, especially for juvenile matters, active investigations, protected information, or people who are not eligible to receive a copy.
Two record products should not be confused with a live roster search. An Arrest Record Letter costs $25, requires the subject of record to appear in person with ID, and covers Stanislaus County arrests only. An Incarceration Letter also costs $25, requires in-person ID, and covers dates and times of incarceration within Stanislaus County jail facilities. For formal charges after prosecution, use the Stanislaus Superior Court portal or courthouse research process instead of treating the jail roster as the final court record.
Stanislaus County Custody Conditions
Population data also depends on facility purpose. The sheriff's detention overview lists church services, counseling, library facilities, vocational and skills workshops, education, recreation, and jail alternatives. The Incarcerated Person Programs page names programs such as Breaking Barriers, high school equivalency, E.L.S.E., Parenting, Alcoholics Anonymous, Women of Wisdom, and Narcotics Anonymous. REACT is the facility most tied to reentry, education, vocational activity, home detention, and Alternative Work Program connections.
Medical and mental-health care are also part of the custody picture. Official health information says each adult detention facility is staffed by licensed medical personnel 24 hours daily for routine and emergency services. Services include new-booking screening, pill call, physician sick call, infirmary coverage, hospital or specialty referral, dental services, and mental-health services. SDC-East is especially important because its facility page identifies a hospital unit, mental-health unit, medical clinic, and dental office.
Stanislaus County Inmate Population FAQ
How large is the Stanislaus County inmate population?
