Search Solano County Inmate Population Records

Solano County Inmate Population Snapshot

The Solano County inmate population is reported through several systems because no single roster covers every person held in or from the county. The Solano County Sheriff-Coroner's Custody Division operates the three adult county jail facilities: Justice Center Detention Facility, Claybank Detention Facility, and Stanton Correctional Facility. Those jails hold pretrial adults, people serving local jail terms, and people held on local warrants, probation matters, or other county-level holds. The sheriff roster uses facility codes 01-JCDF, 02-CDF, and 03-SCF to show which building holds a current inmate.

The county also contains two major California Department of Corrections and Rehabilitation prisons in Vacaville. California Medical Facility and California State Prison, Solano are state prisons, not sheriff jail buildings. A person sentenced to CDCR custody will not remain searchable as part of the current Solano County jail population after transfer. For those prisoners, use CDCR CIRIS, not the county jail roster. Federal Bureau of Prisons and ICE systems are separate again, and the research found no BOP prison or ICE detention facility physically in Solano County.

Solano County Inmate Population Statistics

The strongest local population data comes from the 2022-2023 Solano County Civil Grand Jury report and the BSCC jail profile and rated-capacity materials. The Grand Jury reported three adult county detention facilities with a combined capacity of 1,435 beds and an average daily population of 524 in fiscal year 2022/2023. The later BSCC rated-capacity workbook, last updated April 24, 2026, lists Solano County's current local adult detention rated capacity at 1,439 beds.

Solano County Inmate Population Trends

The Solano County inmate population fell sharply across the Grand Jury's six-year review period. The report states that average daily population declined 39 percent from the 2017/2018 baseline to 2022/2023. It attributed the shift to changes in state law, COVID-19 effects, and broader custody trends. The same report found a cost divergence: fewer people were housed, but the average daily bed rate rose from $178 per day in 2017 to $382 per day in 2022, and annual expense per inmate rose from $65,329 to $139,430.

Solano County Jail Capacity

Capacity did not fall in the same way as the jail count. The Grand Jury said Solano County had expanded jail capacity after state realignment, yet by July 2022 the three adult detention facilities averaged 37 percent occupancy. Justice Center had the largest bed count and the steepest use drop, while Stanton remained the most occupied of the three adult county facilities. The 2026 BSCC workbook later listed Justice Center at 689 rated beds, Claybank at 385, and Stanton at 365.

Because Solano County has two state prisons inside county borders, raw detention counts can be misleading. The county jail population and the state prison population are reported by different agencies, serve different legal stages, and use different search tools.

Who Makes Up Solano County Custody

Official county sources did not publish a current aggregate demographic table for the Solano County inmate population by race, age band, sex, charge level, or hold type in the harvested materials. The public roster shows individual DOB, height, weight, eye color, hair color, sex, facility, charge details, bail, sentence code, and court date, but it does not turn those fields into a public countywide demographic dashboard. That gap matters because a reader should not infer a current demographic mix from one visible roster profile.

The Vera Solano County fact sheet provides useful dated context from 2021. It reported 87 percent of the jail population was pretrial, 32 percent had mental-health needs, 9,979 jail admissions, and 10,545 arrests, with 63 percent of arrests classified as misdemeanors. Vera also reported 738 Solano County residents in the state prison system and 205 people sentenced to state prison that year. Those are high-value context figures, but they should be read as 2021 data rather than a live jail dashboard.

Laws Governing Solano County Jail Data

California law explains why Solano County booking records are public in part, but it also explains why a roster is not a complete investigative file. The county jail booking logs page cites Government Code 7923.610 for seven-day booking data. The broader California Public Records Act opens public records unless an exemption applies, and the state allows withholding when the public interest in nondisclosure clearly outweighs disclosure. Local detention standards and death-in-custody posting duties also shape how jail operations are reported.

Solano County State Prison Population

Solano County has a local jail population and a state prison population within the same county lines. CDCR materials identify California Medical Facility at 1600 California Drive in Vacaville and California State Prison, Solano at 2100 Peabody Road in Vacaville. The CDCR adult institution appendix lists CMF design capacity as 2,316 and CSP-Solano design capacity as 1,904, while CDCR TPOP tables use a 2,594 design-capacity figure for CSP-Solano in population reports. The March 25, 2026 TPOP count reported CMF at 2,136 people, 92.2 percent of design capacity, and CSP-Solano at 3,040 people, 117.2 percent of the TPOP design capacity.

Those CDCR figures should not be merged into the sheriff's jail count. A Solano arrest may start in a county jail, but a prison sentence can move the person into statewide reception and classification. Once that transfer happens, the Solano Sheriff in-custody search is the wrong lookup, and CIRIS becomes the proper public locator.

Search Solano County Inmate Custody

The Solano County inmate population lookup begins with the sheriff's public in-custody search. The user must pass through the disclaimer page, which says the locator is informational, may contain errors or omissions, may omit some inmates, and is not the official record of the Sheriff's Office. The search form has one blank input. It requires at least the first three letters of a first or last name, accepts alphabetic characters only, and also offers Search All.

1. Open the sheriff's in-custody search disclaimer and read the warning about selected offender information.
2. Click I Agree, or open the List of Inmates search form directly if the session permits it.
3. Enter at least the first three letters of the person's first or last name, using letters only.
4. Use Search All when spelling is uncertain or when browsing the public current-custody list is more useful.
5. Open the linked inmate name and compare DOB, facility, inmate number, charges, bail, and court date before taking action.

For more detail on the roster profile and search limits, the Solano County jail inmate records page focuses on the current-custody lookup itself.

Solano County Roster Search Fields

The roster is simpler than many third-party descriptions suggest. It does not provide a public booking-number search field in the captured form. It uses one name box, three command buttons, and sortable result columns. The result table then shows facility code, inmate number, inmate name, DOB, and projected release date when available.

The manifest captured the official roster search form from Solano County's in-custody search.

The screen confirms the three-letter name rule, the Clear button, and the Search All option that are central to the local lookup process.

What Solano County Inmate Records Show

A Solano County jail profile can include a booking-photo area, name, inmate number, projected release date, physical description, facility, booking and charge rows, bail, next court date, and service buttons for commissary, video visitation, VINE, and TouchPay. A sampled live profile showed a photo-unavailable placeholder, which is important for readers looking for mugshots. The page also warned that relying on name alone can cause mistaken identification.

Solano County Booking Logs

The sheriff also publishes Jail Booking Logs for public booking data from the last seven days. The county page says the data is compiled in 24-hour periods and refreshed at midnight. It cites Government Code 7923.610, which is the state statute that supports release of core arrest and booking information. The embedded booking-log application uses start date, end date, and Search fields, with validation limiting the query to the last seven days.

The booking log is not the same as the current in-custody roster. A person may appear in recent booking data and later be released, transferred, or omitted from the current roster. For older booking data, a booking summary, or a booking photo request, use the Records/Warrants Bureau or the county public-records portal.

Solano County Inmate Search Fallbacks

When the online search misses someone, Solano County has several official fallback paths. The county directory lists Custody Booking Information as a 24-hour line at 707-784-7112. The Records/Warrants Bureau handles report requests, booking photos, booking summaries with incarceration dates, and clearance letters, and it states that the bureau has ten days to respond. The same bureau directs court dates, dispositions, warrant checks, and formal court records to Solano Superior Court.

• County jail phone: Justice Center Detention Facility at 707-784-7100 and Custody Booking Information at 707-784-7112.
• Records requests: Records/Warrants Bureau, 530 Union Avenue, Suite 100, Fairfield, CA 94533, 707-784-7010, SHFRecords@SolanoCounty.gov.
• Public-records portal: Solano County Public Records Requests for records not visible on the roster.
• VINE: Solano's VINE instructions route users through VINELink, California, CA_MULTICO, County, and Solano County for release notification.
• No sheriff app: Research found no official Solano County Sheriff mobile app with an app-only roster or warrant lookup.

County Jail vs State Prison Search

Solano County's detention map makes the lookup choice especially important. A person can be physically in Solano County but outside the sheriff's jail roster if they are in CDCR custody at CMF or CSP-Solano. Federal and immigration custody are also separate. VINE is useful for notification, but it is not the official court record, jail record, or prison record.

Solano County Detention Facilities

Facility names matter because the Solano roster may show a code while the public pages use full names. The three adult county detention buildings are sheriff-operated. The two Vacaville prisons are CDCR institutions. The juvenile detention facility is run by the Probation Department and is not an adult inmate-search destination.

• Justice Center Detention Facility - the primary adult county jail in Fairfield, roster code 01-JCDF.
• Claybank Detention Facility - adult county detention facility on Claybank Road, roster code 02-CDF.
• Stanton Correctional Facility - adult county correctional facility on Claybank Road, roster code 03-SCF.
• California Medical Facility - CDCR state prison medical facility in Vacaville, searched through CIRIS.
• California State Prison, Solano - CDCR Level II/III state prison in Vacaville, searched through CIRIS.
• Solano County Juvenile Detention Facility - secure youth detention run by Probation, with confidential juvenile case-file rules.

Solano County Jail Programs

Population trends connect to programs and facility use. Solano County's Inmate Programs and Services page lists Healthright 360 substance-abuse treatment, Chaplain Services, Five Keys Charter School, Inmate Library Service, PEAK Parenting, employment readiness and reentry case management, MIOCR programs, in-custody case management, WRAP, and Veterans Justice Outreach collaboration. The Alternative to Custody program includes work release, work furlough, electronic monitoring, GPS, and alcohol monitoring for eligible sentenced people.

Rourk Vocational Training Center is a distinct Solano detail. The sheriff's Rourk page lists tire servicing, heavy equipment operation, construction, and welding, with union partnerships. The Civil Grand Jury described Rourk as underused because of declining population, shorter sentences, and difficulty placing approved inmates into training. That finding ties a local program directly to the falling Solano County inmate population.

Solano County Custody Terms

Roster records use short terms that can affect release, court timing, and the right lookup system. These plain-English definitions match the local fields documented in the research.
