Boise County Inmate Population Overview
Boise County does not publish a current public jail dashboard, daily population count, or county-run roster page in the official sources reviewed. The local custody source is the Boise County Sheriff's Office, led for current research purposes by Sheriff Scott Turner based on the Idaho Secretary of State election records. The office operates from Idaho City and is tied to a county holding-facility policy. That policy describes temporary custody for people arrested by Boise County deputies and other local law-enforcement agencies. It also requires booking records, photographs, fingerprints, cell assignment records, release records, and inmate checks when people are housed.
The county inmate population picture is broader than the holding room. Vera's Incarceration Trends methods material uses Boise County as an example of a small county that sends people to a jail run by adjacent Ada County. That makes Ada County's inmate roster a practical lookup channel for some people arrested in or from Boise County, even though Boise County and the City of Boise are not the same place. Sentenced felony prisoners move to the IDOC Resident/Client Search. Federal and immigration custody use separate systems.
Boise County Inmate Population Statistics
The best sourced Boise County inmate population figures are indirect. The research found county population and land-area figures, a holding-facility policy with no bed count, and Ada County Jail figures for the adjacent serving jail. The absence of a Boise County capacity number should not be treated as zero beds or no custody. It means the county sources reviewed did not publish a rated capacity, average daily population, or annual booking report for the holding facility.
| Measure | Figure | Source / Year |
|---|---|---|
| Boise County population | 7,610 | U.S. Census QuickFacts, 2020 Census |
| Boise County land area | 1,899.4 square miles | Census profile, 2020 geography |
| Boise County holding-facility capacity | Not published | Boise County sheriff and policy sources reviewed |
| Ada County Jail capacity | 1,116 | Ada County FY2024-2025 Final Adopted Budget Book |
| Ada County Jail Services staffing | 274 | Ada County FY2024-2025 Final Adopted Budget Book |
The Boise County holding-facility policy is still a key source because it describes how the county accounts for people who are booked, housed, moved, or released. It requires a master file or roster board showing current cell assignment and status for each person housed in the facility. That is an internal custody control record, not a public web roster.
Boise County Inmate Population Trends
No official Boise County trend table was located for jail average daily population, booking counts, sex, race, charge level, or overcrowding. The strongest trend data comes from Ada County Jail, the nearby facility that can matter for Boise County custody research. Ada County Sheriff's 2023 annual report listed daily average population by year, while budget books list capacity changes. These figures should be read as serving-jail context, not as a Boise County-only count.
| Year | ADP / Figure | Notes |
|---|---|---|
| 2021 | 936 | Ada County Jail daily average population in the ACSO 2023 Annual Report. |
| 2022 | 1,019 | Ada County Jail daily average population rose above one thousand. |
| 2023 | 999 | Ada County Jail daily average population fell just below one thousand. |
| FY2023 | 1,224 capacity | Ada County FY2022-2023 budget figure. |
| FY2024/FY2025 | 1,116 capacity | Ada County FY2023-2024 and FY2024-2025 budget figure. |
Capacity is not the same thing as a usable bed on a given night. Classification, staffing, medical housing, separation needs, and court transport can all affect where a person is housed. For that reason, a current Boise County custody check still needs a live phone confirmation with the sheriff or the facility holding the person.
Who Makes Up Boise County Custody
Boise County's holding-facility policy describes people arrested in the daily work of the sheriff's department and other local law-enforcement agencies. It does not admit anyone under age eighteen. The policy requires staff to record race, sex, date of birth or age, physical description, address, phone, marital status, education, emergency contact, and identification numbers at intake. Those intake fields show what the county keeps internally, but they are not all public roster fields.
- Pretrial detainees are people booked after arrest while charges, court dates, bond, or holds are being sorted out.
- Short-term local custody can include people awaiting release, transfer, or first court appearance.
- Serving-jail records may appear through Ada County if a person from Boise County is housed there.
- Sentenced state prisoners move into IDOC custody and should be searched in the state locator.
- Federal or ICE custody uses BOP, U.S. Marshals, or ICE channels, not a Boise County roster.
Laws Governing Boise County Jail Data
Idaho public-records law gives the baseline for jail and booking record access, but law-enforcement records get a closer review than ordinary county records. Boise County's Records Section says requests must be written and specific, complete names and identifying details are needed for records about a person, and no information is released based on telephone requests. The same county page warns that open investigations, privacy, and fair-trial concerns can limit release.
Key Idaho access rules:
Idaho Code 74-102 makes public records open for inspection and copying unless a statute exempts them.
Idaho Code 74-103 sets agency response timing for public-records requests.
Idaho Code 74-124 protects certain investigatory records but excludes basic arrest information from that definition.
Idaho Code 31-2202 places jail and prisoner duties within the sheriff's statutory role.
The Idaho Sheriffs' Association jail-services material adds statewide context. It says Idaho jail standards were implemented in 1978 and that Idaho's jails are inspected annually. Boise County's own policy repeatedly cites Idaho Jail Standards for housing, supervision, discipline, and facility operations.
How to Search Boise County Inmates
A Boise County inmate search has to follow a fallback chain because no official Boise County online roster was found. Start with live custody status through the sheriff's main number. If the question is about records rather than current custody, use the Records Section and submit a written request. If staff say the person was moved to the adjacent serving jail, use Ada County Jail's public roster and confirm status by phone or in person.
- Call the Boise County Sheriff's Office with the person's full legal name and date of birth.
- Ask whether the person is in the holding facility, released, moved to Ada County Jail, or held on another agency matter.
- For records, contact the Boise County Sheriff's Records Section and prepare a written public-records request.
- Search Ada County Jail by last-name prefix if the person may be housed in the regional jail.
- Use IDOC, BOP, ICE ODLS, iCourt, and VINELink when the custody stage points outside Boise County.
The Ada County roster states that its database updates every twenty-four hours and that status is confirmed only by phone or in person. It excludes juvenile offenders and shows bail only for charges where release is an option. That makes it useful, but not final, for a person who may have been transferred from Boise County custody.
Boise County Roster Search Fields
Because Boise County does not publish a local roster interface, the practical public roster search-field table comes from Ada County's official roster. The interface uses a last-name-prefix search. A hidden person ID drives the detail pane when a result is opened. The roster also prompts users to register for custody notifications.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Type first letter(s) of last name | Text | Yes | The interface alerts users if the last-name field is blank. |
| Search | Button | n/a | Runs a last-name-prefix search. |
| Hidden Person ID | System field | n/a | Used by the roster to load the detail or mugshot pane. |
For a visual match to the roster channel, the Ada County Sheriff inmate roster page is the source for this search interface.
The screenshot shows why Boise County readers need to know the difference between the county holding facility and the larger regional jail search tool.
What Boise County Inmate Records Show
The local Boise County holding-facility file is broader than any public roster. The policy requires booking and intake records, court orders, photographs and fingerprints, property inventory, account records, classification records, program records, disciplinary reports, grievances, incident reports, release records, and medical files. Public release of those items depends on Idaho law and county review.
| Record Source | Common Public Fields | Limits |
|---|---|---|
| Ada County roster | Name, JID number, age, arresting agency, charges, severity, type, bail, VINE prompt. | Updates daily and does not include juveniles. |
| Boise County Records Section | Booking record, incident record, or booking photo when releasable. | Written request required, with review and possible fees. |
| IDOC Resident/Client Search | Name, IDOC number, status, age, offense, sentencing county, case number, sentence status. | Only active IDOC jurisdiction, custody, or supervision data. |
| iCourt portal | Case status, hearing search, payments, and filed court charges. | Sealed or exempt information does not appear. |
Boise County Jail vs State Prison
Many search errors come from using the wrong custody system. A Boise County arrest can begin at the holding facility, but the person may be released, transferred, kept at Ada County Jail, or moved into state or federal custody. Once a felony sentence places someone under IDOC jurisdiction, the county jail is no longer the main lookup source.
| Custody Type | Where to Search | Best Use |
|---|---|---|
| Boise County arrest or short local hold | Boise County Sheriff's Office and Records Section | Live custody, booking, release, and records questions. |
| Regional jail housing | Ada County Jail roster | People held in Ada County Jail, including possible Boise County transfers. |
| State prison, probation, or parole | IDOC Resident/Client Search | Sentenced felony custody or supervision. |
| Federal custody | BOP Inmate Locator or U.S. Marshals District of Idaho | Federal inmates or pretrial federal detainees. |
| Immigration detention | ICE Online Detainee Locator System | Detainees held under immigration authority. |
Boise County Public Records Requests
The Boise County Sheriff's Records Section handles storage, retrieval, management, and repository functions for official sheriff reports and records. The page says a written request is required, the request should be specific, and no information is released pursuant to telephone requests. For records about a person, complete names plus dates of birth or Social Security numbers may be needed to identify the right record.
Copying fees must be paid before release. The county also warns that private information, victim information, personal identifiers, criminal-history restrictions, and open investigation concerns can lead to withholding or redaction. Narrow requests work better than broad ones. Ask for a booking sheet, booking date, booking photo, incident number if known, and requested delivery method.
Boise County Custody Terms
Short definitions help separate the holding-facility record from court and prison records.
- Booking
- The administrative entry into custody after arrest, including identity, charges, property, and screening.
- Holding facility
- A short-term jail setting for temporary county custody.
- Detainer
- A notice or request from another agency that can affect release.
- Classification
- A jail housing and security assessment.
- Not bailable
- A custody status where a listed charge or hold is not eligible for release by bond.
Boise County Detention Facilities
The facility map for Boise County has two relevant entries. The first is the county's own sheriff holding facility. The second is the Ada County Jail, included because high-authority research notes that Boise County sends people to a jail run by adjacent Ada County.
- Boise County Sheriff's Office Holding Facility holds people arrested by the sheriff and local agencies in a temporary county setting.
- Ada County Jail is the regional jail channel with the strongest official online roster for nearby custody checks.
The official Boise County Sheriff's Office page is the local starting point for custody questions, records routing, and facility contact information.
The sheriff contact source matters because Boise County does not offer a public roster page that replaces a direct custody confirmation.
Boise County Inmate Population FAQ
How big is the Boise County inmate population?
Boise County did not publish a current jail average daily population, booking count, or holding-facility capacity in the official sources reviewed. The most useful sourced numbers are the county's 2020 Census population and the Ada County Jail capacity and annual average population figures that matter for regional custody research.
How do I search the Boise County inmate population?
Start with the Boise County Sheriff's Office for live custody status. Then use the Records Section for written records requests, Ada County Jail's roster for possible regional housing, iCourt for filed charges, IDOC for sentenced state custody, and BOP or ICE for federal or immigration custody.
Does Boise County have an online jail roster?
No official Boise County online roster, recent-bookings feed, or mugshot gallery was located. The county provides sheriff and records contacts plus a holding-facility policy. Ada County's roster is relevant when a person is housed in the adjacent regional jail.
Can I look up past Boise County inmates?
Past custody usually requires a written public-records request to Boise County or a court lookup in Idaho iCourt. Sentenced people may appear in IDOC if they remain under active state custody or supervision. Released people may not remain visible in a jail roster.
