Placer County Inmate Population Overview
Placer County's local jail population is held in two sheriff-operated facilities: Auburn Jail and South Placer Jail. Both are run by the Placer County Sheriff's Office Corrections Division. The county jail count includes people booked by local agencies, people waiting for court, people serving county jail sentences, and people held on warrants or other local holds. It does not include people already transferred to the California Department of Corrections and Rehabilitation, a federal prison, or ICE detention.
Official population data comes from the state Board of State and Community Corrections Jail Profile Survey, which gathers county-reported jail figures. The 2025 monthly data inspected for Placer Sheriff's Department showed average daily population moving between 761 and 826 people. That count changes with arrests, bail decisions, court calendars, releases, medical transport, transfers between Auburn and South Placer, and state-prison commitments after sentencing.
Placer County Inmate Population Statistics
The strongest Placer County inmate population figures in the research file come from the BSCC Jail Profile Survey, the BSCC Placer public summary, and the official county facility pages. BSCC monthly data for 2025 showed a spring peak, a lower late-year count, and 9,516 annual bookings when the monthly booking totals are added. Capacity is more nuanced. South Placer Jail has a phase-one rating of 420 inmates, while Auburn Jail has several historical ratings that must be read with the closed minimum-security barracks in mind.
| Measure | Figure | Source / Year |
|---|---|---|
| 2025 monthly average daily population range | 761-826 | BSCC JPS query, 2025 |
| 2025 highest one-day population range | 793-849 | BSCC JPS query, 2025 |
| Annual bookings from monthly sum | 9,516 | BSCC JPS query, 2025 |
| South Placer phase-one rated capacity | 420 | Official South Placer Jail page |
| 2015 average daily population | 628.4 | BSCC Placer public data summary |
Placer County Jail Population Trends
Historic BSCC data shows Placer's average daily jail population rose from 526.8 in 2011 to 659.9 in 2014, then eased to 628.4 in 2015. The later 2025 monthly data inspected in the research file sits above those 2011 through 2015 annual levels. The 2025 year was not flat. April had the highest monthly ADP at 826, May had the highest monthly booking total at 856, and November had the lowest monthly ADP at 761.
South Placer Jail helps explain part of the local trend. The county planned that jail as western Placer County grew, but the official facility page notes that California Realignment in 2011 affected Auburn's average daily population and delayed sustainable operating funding after the building was largely completed. Phased operation began after the FY 2013/2014 budget process, with a four-pod main jail housing unit and two minimum-security pods.
| Period | Average Daily Population | Notes |
|---|---|---|
| 2011 | 526.8 | BSCC Placer summary baseline year in research |
| 2014 | 659.9 | Highest annual ADP in the 2011-2015 table |
| 2015 | 628.4 | 543.7 male ADP and 84.7 female ADP |
| April 2025 | 826 | Highest monthly ADP in inspected 2025 data |
| November 2025 | 761 | Lowest monthly ADP in inspected 2025 data |
Who Makes Up Placer County Jail Custody
The Placer County inmate population is not one legal category. It includes unsentenced people awaiting court, sentenced county jail inmates, people held on warrants, and people held pending transport or further review. In the BSCC 2015 public summary, 68.8% of the jail ADP was unsentenced and 31.2% was sentenced. The same summary reported 86.5% male and 13.5% female ADP. The 2025 monthly data inspected included felony and misdemeanor ADP measures, but the research did not provide jail race or age tables for 2025.
- Unsentenced custody means the person is waiting for court action, trial, plea, or sentencing.
- Sentenced county custody means the person is serving local jail time, not a CDCR prison term.
- Warrant and hold custody can include out-of-county warrants, probation holds, parole holds, or other agency detainers.
- State prison custody starts after a qualifying sentence and transfer to CDCR, not while the person remains on the Placer roster.
Placer County Jail Capacity
Auburn Jail capacity should be described with care. The official Auburn page says the 1985 facility was first rated for 108 inmates, then the population quickly exceeded that rating. A 1990 federal court order restricted the daily population to 148, and a 260-bed addition opened in 1992. The page also describes former minimum-security barracks with 160 beds in World War II-era warehouse buildings, but those barracks closed on May 31, 2014, and inmates moved to South Placer Jail.
South Placer Jail has clearer current phase-one figures in the captured official source. Its first phase is about 200,000 square feet and rated for 420 inmates. The same page says the infrastructure was planned for a later buildout to a 319,000-square-foot facility with 980-inmate capacity. Those buildout numbers are planning context, not a current jail population count.
Laws Behind Placer County Jail Records
California law makes core arrest and jail information public while still allowing safety, investigation, juvenile, and criminal-history limits. Government Code 7920.000 is part of the California Public Records Act framework. Government Code 7923.610 covers specified arrest information such as name, physical description, arrest and booking times, bail, current holding location or release manner, and charges, subject to stated exceptions.
Key Placer County record rules:
Penal Code 13300 limits full local summary criminal history information, so a single booking record is different from a full rap sheet.
Title 15 Minimum Standards set statewide jail rules for classification, grievances, health care, and local detention operations.
BSCC in-custody death review rules cite state reporting and review duties for deaths in local detention.
How to Search Placer County Inmates
The current local search path is the Placer County Sheriff's Office Who's In Custody portal. The official Corrections page says to use that site for the most recent inmate information. The portal is separate from the county's main CivicPlus site and is hosted through ATIMS/LE. Static research could not confirm the rendered field labels or a sample public profile, so the safest use is to search by the person's name and then confirm any uncertain result by phone.
- Open the official Who's In Custody portal from the sheriff's Corrections page or by direct URL.
- Search for the person in Placer County jail custody using the information available from the arrest or family contact.
- Review the result for current holding location, charges, bail, court date, or other visible custody details.
- Call Auburn Jail at 530-745-8500 or South Placer Jail at 916-409-8100 if the person is newly booked or not found.
- Switch to CDCR, BOP, or ICE only when the person may be in state, federal, or immigration custody.
Placer County Roster Search Fields
The research file found that the public portal renders its search controls through JavaScript, so exact Placer field labels were not visible in static HTML. That matters because a page should not invent search boxes that were not documented. Use the official portal first, then use the jail phone lines or the PCSO NextRequest portal when a booking, photo, or older custody record is not visible online.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Visible labels not captured | JavaScript-rendered form | Unspecified | The official portal served an app shell during static inspection. |
| Search controls | Rendered buttons or inputs | Unspecified | Use the live portal, then verify uncertain results with the jail. |
| Public-record request details | NextRequest web form | Depends on request | Delivery options include web, email, phone, in person, fax, and mail. |
What a Placer County Inmate Record Shows
A live Placer inmate profile could not be inspected from static access, so the reliable field list comes from state arrest-disclosure law, the jail rulebook, and the county bail page. A Placer jail record may use a jail identification number or P#. The bail page also says licensed bail agents receive bail amount, charges, court case number, court date or department, and jail identification number for bond processing.
| Field | What It Shows |
|---|---|
| Name | Person booked or held in Placer County jail custody. |
| Jail ID / P# | Local jail identifier, different from a CDCR number. |
| Booking date and time | Core arrest information under California law when releasable. |
| Current facility | Auburn Jail or South Placer Jail if the person is locally held. |
| Charges and holds | Arrest charges, warrants, probation holds, parole holds, or other disclosed holds. |
| Bail and court details | Bail amount, court date, department, or case number when available. |
Placer County Jail vs State Prison
Many failed inmate searches happen because the search starts in the wrong custody system. Auburn Jail and South Placer Jail hold local county jail custody. CDCR holds sentenced state prisoners after court commitment and transfer. BOP and ICE are separate federal systems. No adult CDCR prison, BOP prison, or ICE detention facility was identified inside Placer County in the official locator research.
| Custody System | Who It Covers | Where to Search |
|---|---|---|
| Placer County jail | Pretrial detainees, county sentences, local holds | Who's In Custody |
| California state prison | Sentenced prisoners transferred to CDCR | CDCR CIRIS |
| Federal custody | Federal sentenced inmates and some released records | BOP inmate locator |
| Immigration detention | Adults in ICE custody or CBP custody over 48 hours | ICE ODLS |
State Federal and ICE Search
CDCR's California Incarcerated Records and Information Search is the statewide locator for sentenced state custody. A CDCR number is best, but name searches may work with enough identifying information. CDCR's contact page says the Identification Unit can help with CIRIS viewing issues at 916-445-6713 on weekdays, excluding holidays, during the posted state hours. VINELink is also available as a notification supplement for custody and release alerts.
Federal cases follow a different path. The U.S. Attorney's Office for the Eastern District of California covers federal prosecution in the region, and the U.S. Marshals Service Eastern District of California handles federal detainee transport and holding logistics. A federal pretrial detainee may not appear in BOP until committed to BOP custody. For immigration detention, use ICE ODLS and the ICE fact sheet fallback, including DRIL at 1-888-351-4024 when ODLS does not return a result.
Placer County Detention Facilities
The Placer County inmate population is divided between two county jail sites. The sheriff's Corrections Division runs both, but they serve different parts of the county's operating plan. Auburn is the older jail in the county government campus area. South Placer is the newer Santucci Justice Center facility serving growth in Roseville, Rocklin, Lincoln, Loomis, and the western county.
- Auburn Jail holds county jail inmates, pretrial detainees, sentenced county jail inmates, and people booked by Placer County agencies.
- South Placer Jail includes intake and booking, medical services, programs, video visitation, and minimum-security housing transferred from Auburn's closed barracks.
Placer County Records Requests
When the roster is not enough, the sheriff's official fallback is the PCSO public-records portal at pra.placersheriff.org. Use it for booking records, custody records, incident or arrest records, and booking photos not visible online. For court filings after a jail arrest, use Placer Superior Court Online Case Access or the court records copy process instead of the jail roster.
The Placer County Sheriff mobile app also exists on Google Play and Apple's developer page. The app-store text found in research describes public-safety news, reporting crimes, submitting tips, and interactive sheriff features. It did not prove an app-only inmate roster or warrant lookup, so the official roster and public-records portal remain the documented custody channels.
Placer County Inmate Population FAQ
How large is the Placer County inmate population?
BSCC 2025 monthly data inspected for Placer Sheriff's Department showed average daily population between 761 and 826 people. That is a monthly range, not a live count. For a current person-by-person custody check, use the sheriff's Who's In Custody portal.
Where do current Placer County inmates appear?
Current county jail custody is searched through the official Who's In Custody portal. If a same-day arrest does not appear, call Auburn Jail or South Placer Jail because booking, release, transport, and court movement can cause timing gaps.
Are state prisoners counted in Placer County jail data?
No. Once a person is sentenced and transferred to CDCR, the search moves to CIRIS. County jail population data and the Placer roster cover local sheriff custody, not the statewide prison population.
