Mono County Inmate Population
The Mono County inmate population is centered on one local detention facility, the Mono County Jail in Bridgeport. The jail is operated by the Mono County Sheriff's Department and holds people booked by the sheriff and other local agencies, people waiting for court, and people serving local jail terms. It is not a state prison and it is not a federal detention center. That distinction controls where a search should begin.
For current county custody, the official public source is the Mono Sheriff's Citizen RIMS incarcerated-people roster. Once a defendant is sentenced to state prison and received by the California Department of Corrections and Rehabilitation, the lookup moves to CDCR CIRIS. Federal and immigration custody use separate systems. In a rural county with long travel distances and a small jail, the public roster count is best treated as a point-in-time custody list, not as a yearly average.
Mono County Jail Population Statistics
The strongest current custody figure in the research is the Citizen RIMS count captured on May 31, 2026. It showed 22 public in-custody records for Mono County. The public configuration also showed that the inmate roster was enabled, while public arrests, public warrants, and public most-wanted features were not enabled for Mono County display. Those settings explain why the jail roster can be useful while related public searches in the same platform do not work.
The capacity figure comes from Mono County SB 844 and BSCC jail project materials, which describe the current rated capacity as 48 beds. A later county jail groundbreaking release describes the replacement jail as approximately 50 beds. Those are capacity and planning figures. They should not be turned into annual booking totals or average daily population because the research did not extract official yearly BSCC totals for Mono County.
| Measure | Figure | Source / Date |
|---|---|---|
| Current public roster count | 22 in-custody records | Citizen RIMS API and roster, inspected 2026-05-31 |
| Public inmate roster enabled | Yes | Citizen RIMS agency configuration, inspected 2026-05-31 |
| Public booking photos enabled | No | Citizen RIMS agency configuration, inspected 2026-05-31 |
| Existing rated capacity | 48 beds | Mono County SB 844 / BSCC jail project materials |
| Replacement jail planned capacity | Approximately 50 beds | Mono County groundbreaking release, 2025-09-02 |
| Annual bookings | Not published in inspected official pages | Sheriff and roster sources did not provide a figure |
Mono County Inmate Population Trends
Mono County's public research did not provide a full multi-year official average daily population table. The available data supports a narrower statement: the public roster count on May 31, 2026 was 22, and the county's planning materials identify a 48-bed current rated capacity. For a small Eastern Sierra county, that point matters. A few bookings, releases, or transfers can create a large percentage change without proving a long-term trend.
The better trend story is infrastructure and access. Mono County has a replacement jail project under construction, while the current custody search still runs through the Bridgeport jail roster. The county's new jail project page describes construction from August 2025 to August 2027 and occupancy or inmate move-in from August to November 2027. The county groundbreaking release describes a future 221 Twin Lakes Road facility with roughly 50 beds.
| Year or Date | Population Figure | How to Read It |
|---|---|---|
| 2026-05-31 | 22 current public records | Point-in-time roster count, not ADP |
| 2025 | Not extracted | Use BSCC Jail Profile Survey for official annual data |
| 2024 | Not extracted | No official figure in the research file |
| 2023 | Not extracted | No official figure in the research file |
Mono County Inmate Population Sources
The official county custody list is more useful than a general people-search result because it is tied to the sheriff's own public roster configuration. The sheriff jail page routes the public toward Citizen RIMS for law-enforcement information. The specific inmate route is the incarcerated-people page, and the agency configuration showed that records must have booking complete before public inmate display.
The California BSCC Jail Profile Survey is the statewide source to consult for formal jail capacity and population reporting. The research file notes that the BSCC profile page was identified but that annual figures were not extracted into the project research. That means the site can cite BSCC as the proper official data channel without inventing a county trend line.
The BSCC jail profile survey page is the statewide source shown in the screenshot manifest for jail population and capacity data.
Use that source for official annual jail profile data, while using the sheriff roster for current Mono County jail custody status.
Who Makes Up Mono County Custody
Mono County Jail custody includes people booked after local arrests, people held before court, people remanded by the court, and people serving local jail sentences. The public roster does not publish housing unit or classification status, so it should not be used to infer where a person sleeps inside the jail. It does show basic public demographics and charge information.
The roster configuration enabled name, age, sex, and race. It disabled date of birth, height, weight, hair color, eye color, build, complexion, real address, and mugshot display. Sample public records included misdemeanor and felony charge levels, per-charge bail amounts, and total bail fields. Those fields help identify a custody record, but they do not replace the court file or the prosecutor's later filing decision.
- Pretrial detainees: People held before arraignment, bail review, release, plea, trial, or dismissal.
- Local sentenced inmates: People serving a county jail term or court-ordered local custody.
- State prisoners: People sentenced and transferred to CDCR, searched through CIRIS rather than Mono Citizen RIMS.
- Federal or immigration detainees: People searched through BOP, U.S. Marshals, or ICE systems after transfer from local custody.
Mono County Jail Capacity
Mono County's jail capacity discussion is tied to its jail replacement project. The current sheriff jail page did not publish a rated capacity, but the project materials cited in the research say the county did not foresee adding beds beyond the current rated capacity of 48. The county's 2025 groundbreaking release describes the replacement facility as approximately 27,000 square feet, approximately $30.5 million, and approximately 50 beds.
Those facts support a careful capacity statement, not an overcrowding claim. No official recent consent decree, jail litigation page, or Mono-specific death-in-custody investigation page was located in the inspected source set. The page should therefore state what is known: the jail is small, the public roster count was below the cited rated capacity on the inspection date, and a replacement facility is planned but was not the active custody site in the research.
Mono County Jail Record Laws
California law shapes what Mono County inmate population records can show. The California Public Records Act gives public access to many local agency records unless an exemption applies. Law-enforcement investigatory records, juvenile records, medical data, sealed matters, and some victim or witness information can still be withheld or redacted. Jail custody data is public in some forms, but the law does not make every booking detail open to every requester.
Key law and standards:
California Public Records Act sets the broad access rule for local agency records.
Government Code section 7923.610 addresses law-enforcement investigatory records and disclosure limits.
Penal Code section 4000 covers county jail custody under legal authority.
Penal Code section 6031.1 supports BSCC minimum standards for local detention facilities.
Search Mono County Jail Inmates
The current inmate search starts with the Mono County Sheriff's Department Citizen RIMS roster. It is the official public web roster for people currently listed as incarcerated in county custody. It does not require a public user account in the browser. The search can be narrowed by name, and the public list should be checked against booking date, arrest agency, status, charges, and bail because names can be similar.
The roster is not a promise of immediate display after every arrest. The agency configuration requires booking completion before a person can appear publicly. If a new arrest is not visible, the person may still be in booking, may have been cited and released, may have been sent to another agency or hospital, or may be in a court or federal process outside the public county roster.
- Open the Mono Citizen RIMS incarcerated-people roster.
- Confirm the page is for the Mono County Sheriff's Department.
- Use the page search or filter controls to narrow the current list by name.
- Review the matching result for booking date, status, charge lines, and bail fields.
- If the person was sentenced to prison, switch to CDCR CIRIS.
- If the person may be federal or immigration custody, check BOP, ICE, or U.S. Marshals channels.
Mono County Roster Search Fields
The roster route is an incarcerated-people page rather than a broad public arrest feed. The research captured both the user-facing page and the Citizen RIMS API behavior. The agency ID and Mono prefix are handled by the app, not entered by the public user. Public results inspected on May 31, 2026 showed in-custody records.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Incarcerated People | Route/page | n/a | Public route for current Mono County incarcerated people. |
| Name / search text | Text filter | Unspecified | Used to narrow visible roster results. |
| Agency | Hidden configuration | Yes internally | Agency ID 337 and prefix monosheriff are handled by Citizen RIMS. |
| Status | Result field | Not user entered | Inspected public records showed In Custody. |
The official Citizen RIMS incarcerated-people page is the roster interface shown in the project screenshot set.
The screenshot supports the core routing point: current jail custody uses the incarcerated-people roster, while arrests, warrants, and mugshot searches need different explanations.
Mono County Inmate Record Fields
A Mono County jail record can show useful booking and charge data without showing every internal jail field. Public records captured in the research included booking identifiers, agency codes, arrest timing, booking timing, original arrest location, status, visible demographics, charge arrays, bail amounts, and total bail. The public configuration disabled photos and several physical descriptors.
| Field | What It Shows |
|---|---|
| Full name | Last, first, and middle name format in the public record. |
| Booking ID | Internal booking identifier useful when contacting jail or records staff. |
| Booking date/time | When the jail booking was recorded. |
| Original arrest date/time | When the arrest event occurred. |
| Status | Public custody status, such as In Custody in inspected records. |
| Charges | Charge code, description, level, counts, arresting agency, and bail line. |
| Mugshot | Not displayed because inmate photos were disabled. |
| Court date | Not visible in inspected public records. Use Mono Superior Court. |
Mono County Booking and Bail
Booking is the jail intake event after arrest or surrender. It can include identity checks, property inventory, search, fingerprints, internal photo capture, medical or mental-health screening, classification, charges, and bail fields. In Mono County, the public roster distinguishes original arrest date and booking date, which helps explain why a recent arrest may not show as soon as someone hears about it.
Mono Citizen RIMS records include bail amounts per charge and a total bail field. Several inspected records showed zero-dollar bail values, but zero should not be read as automatic release. A no-bail hold, warrant, court remand, probation or parole hold, federal hold, or other agency detainer can still block release. The sheriff jail page says the department does not refer a specific bond agency, and the closest bail or bond companies are in Bishop and South Lake Tahoe.
| Release Term | Plain Meaning | Mono County Search Note |
|---|---|---|
| Cash bail | Full amount posted as directed by the court or jail. | Call the jail before bringing funds. |
| Surety bond | A licensed bail agent posts the bond. | The sheriff does not recommend a specific agency. |
| Own recognizance | Release on a promise to appear, sometimes with conditions. | Set by the court, not fully explained by the roster. |
| No-bail hold | Release is blocked for that hold until cleared. | May not be obvious from a low local bail line. |
Mono County Custody Lookup Channels
Each custody system covers a different stage. Current county jail custody starts with Citizen RIMS. Court charges and hearing dates belong to Mono Superior Court. State prison custody after sentencing belongs to CDCR. Federal prison, federal pretrial custody, and immigration detention do not use the county roster after transfer.
| Custody or Record Type | Correct Source | Use It For |
|---|---|---|
| Current Mono County jail custody | Citizen RIMS | Current in-custody roster records. |
| Filed criminal case | Mono Superior Court case information | Charges filed after arrest, hearings, and dispositions. |
| State prison custody | CDCR CIRIS | Sentenced California prisoners after transfer. |
| Federal custody | BOP inmate locator | Sentenced federal prisoners and many releases since 1982. |
| Immigration detention | ICE ODLS | Immigration detainee searches. |
| Custody notification | VINELink | Notification where California or Mono data is available. |
The CDCR CIRIS locator is the California state-prison search channel for a Mono County case after a state prison transfer.
That state locator is separate from the Mono County jail roster and should not be used for a person still held in local jail before sentencing.
Mono County Detention Facility
The facility map resolved one public-facing detention facility for the site. City arrests in Mammoth Lakes, Lee Vining, June Lake, Bridgeport, Walker, and other Mono County areas normally route to the county jail if the person is held locally. No separate public municipal jail, CDCR prison, BOP institution, or dedicated ICE detention facility was identified in Mono County.
- Mono County Jail holds local pretrial detainees, people booked by the sheriff and local agencies, and locally sentenced or court-ordered inmates.
Mono County Jail Terms
Several common words mean different things in the jail, court, and prison systems. Reading a custody record is easier when the record type is clear.
- Booking
- The jail intake event when a person is recorded in custody after arrest, surrender, warrant, or court remand.
- Arrest charge
- The law-enforcement allegation listed at or near booking. It can differ from the charge later filed in court.
- Filed charge
- The formal charge filed by the District Attorney in Mono Superior Court.
- Detainer
- A hold or request from another agency that may stop release from the local jail.
- Classification
- The jail's internal housing and security assessment. Mono does not publish housing unit in the public roster.
Mono County Inmate Population FAQ
