Custer County Inmate Population Overview
The Custer County inmate population is centered on one local detention facility: Custer County Jail, operated by the Custer County Sheriff's Office. Official county materials say the sheriff operates the jail, serves court papers, enforces state and local law, and coordinates with other law enforcement agencies. That makes the sheriff's office the first local point for custody confirmation when no public jail roster is posted.
Official sources did not show a county-hosted jail roster, current-bookings page, mugshot gallery, or live jail dashboard. That absence matters. Readers looking for the Custer County inmate population should treat the jail phone line, the written public-records process, VINELink, Idaho iCourt, and the Idaho Department of Correction locator as separate access channels. Each one answers a different custody question.
Custer County Inmate Population Statistics
The most direct published jail figures come from the Idaho Sheriffs' Association directory of Idaho jails. Its Custer County Jail entry lists the local jail with a rated capacity of 8 and an average daily population of 3. Those figures describe the local jail directory snapshot, not a live count for the current hour.
| Measure | Figure | Source / Year |
|---|---|---|
| Custer County Jail average daily population | 3 | Idaho Sheriffs' Association directory, crawled 2026 |
| Custer County Jail rated capacity | 8 | Idaho Sheriffs' Association directory, crawled 2026 |
| Inmates housed out of county | 2 | Custer County commissioner minutes, October 14, 2025 |
| County population estimate | 4,636 | Census QuickFacts, July 1, 2025 |
The Idaho jail directory screenshot captured for this build is useful because it ties the Custer County inmate population to a statewide jail directory rather than a commercial jail profile.
The directory image supports the capacity and average-population figures used here, while the sheriff's office remains the source to call for current custody.
Custer County Jail Population Trends
Custer County does not publish a current jail-statistics dashboard in the official sources inspected. The available trend picture comes from a mix of the Idaho Sheriffs' Association directory, Custer County commissioner minutes, and the Vera Institute county incarceration trends dataset, which is drawn from BJS and related sources. Because Custer County's jail population is very small, one or two people can change the local rate sharply.
| Year or Date | Count / ADP | Notes |
|---|---|---|
| 2026 directory snapshot | ADP 3 | Idaho Sheriffs' Association also lists capacity of 8. |
| October 14, 2025 | 2 out of county | Commissioner minutes noted two inmates housed outside Custer County. |
| 2019 | 4 | Vera/BJS-derived county jail population row. |
| 2018 | 4 | Vera/BJS-derived county jail population row. |
| 2015 | 3 | Vera/BJS-derived county jail population row. |
| 2010 | 5 | Vera/BJS-derived county jail population row. |
Those figures show why the Custer County inmate population should not be read like a large urban jail total. A directory ADP of 3 suggests a low in-building count, but the 2025 out-of-county note shows the county may still carry custody responsibilities for people not physically inside the Challis jail.
Custer County Inmate Population Makeup
No current official Custer County jail demographic report was located. The safest local description is functional rather than demographic: the jail population can include local pretrial detainees, people serving short county sentences, court holds, and people awaiting transfer. A person may also be moved outside the county when bed space, transport, classification, court, or medical factors require it.
Historical Vera data includes a 2019 row with a total jail population of 4, all listed as male and white in that dataset. That row is useful as older context, but it should not be treated as a current demographic profile. Custer County's general population context comes from Census QuickFacts, not from a jail-specific report.
- Pretrial detainee
- A person held after arrest while charges, bond, or court hearings are pending.
- County sentence
- A short local sentence served in the county jail rather than state prison.
- Detainer or hold
- A request or order from another agency that can prevent release even after local bond is addressed.
- Out-of-county housing
- Custody for a Custer County case while the person is physically held in another county jail.
Custer County Jail Capacity
The Custer County jail capacity story is more detailed than the current count. The official county record includes a June 24, 2019 commissioner proceeding that described a tour through dispatch, driver's-license testing, the jail kitchen, cells, and exercise yard, along with a jail-compliance dilemma. February 23, 2022 minutes mention efforts to get a new jail.
August 19, 2025 public-hearing minutes add a strong local note: the minutes state the jail was built in 1907, describe it as the oldest active jail in the USA, and say the county needs permission each year to keep using it. That is a county-hearing statement, so it should be read as local government context rather than an independently audited national ranking.
Capacity note: The directory ADP of 3 is below the listed capacity of 8, but out-of-county housing can still affect the Custer County inmate population.
Custer County Inmate Population Laws
Idaho public-records and jail statutes shape what can be inspected, what may be withheld, and who keeps custody records. These laws do not create a public online roster for Custer County. They set the public-records framework for requests, fees, exemptions, jail custody, and booking-photo limits.
Key statutes:
Idaho Code § 74-102 gives the public a right to inspect and copy public records unless an exemption applies.
Idaho Code § 74-103 governs agency response timing and fee procedures for public-records requests.
Idaho Code § 74-105 covers law-enforcement investigatory records and related exemptions.
Idaho Code § 20-601 is the booking-photo and county-jail confinement statute relevant to mugshot access.
Idaho Code § 20-602 supports the local rule that the sheriff keeps county jail prisoners.
Custer County and IDOC Custody
The Custer County inmate population is separate from Idaho state-prison custody. Once a person is sentenced to state custody, placed on Idaho probation, or moved to parole supervision, the Idaho Department of Correction Resident/Client Search becomes the better lookup tool. IDOC states that its locator covers people on court probation or under IDOC jurisdiction, including incarcerated, probation, and parole status.
| Question | Custer County Jail | Idaho DOC |
|---|---|---|
| Who is covered? | Local pretrial detainees, short county sentences, court holds | Sentenced state prisoners, probation, parole |
| Who operates it? | Custer County Sheriff's Office | Idaho Department of Correction |
| Best lookup route | Call jail, VINELink, records request | IDOC Resident/Client Search |
| Where are facilities? | Challis jail, with possible out-of-county housing | State prisons outside Custer County |
Search Custer County Inmate Custody
A Custer County inmate search should start with the custody stage. A new arrest belongs first with the jail or sheriff's office. A filed criminal case belongs in Idaho iCourt. A sentenced felony case belongs in IDOC. Federal and immigration custody use federal systems. Searching all of them in order prevents a common error: assuming a missing county roster result means the person is not in custody anywhere.
- Call the Custer County Sheriff's Office at (208) 879-2232 to ask about current custody, physical housing, and out-of-county placement.
- Use VINELink for custody-status and victim-notification searches tied to participating agencies.
- Search Idaho iCourt if the arrest has led to a public criminal case or hearing.
- Use the IDOC Resident/Client Search after sentencing, probation, or parole.
- Use the BOP inmate locator, U.S. Marshals District of Idaho, or ICE detainee locator for federal or immigration custody.
Custer County Inmate Lookup Fields
Because no official Custer County online roster was located, there is no county roster form with verified public search fields, filters, update time, or profile pages. The table below preserves that finding instead of replacing it with a generic roster form.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| No official Custer County jail roster located | n/a | n/a | The county site did not publish roster fields, booking filters, release retention, or profile pages in the sources inspected. |
For sentenced Idaho custody, the IDOC locator does publish search fields and update cautions. IDOC says data is updated daily but may not show the most current status, location, mailing address, or scheduled termination date.
| IDOC Field | Type | Required | Notes |
|---|---|---|---|
| Last Name | Text | Conditionally required | Last name or IDOC number required; partial last-name searches need at least two characters. |
| First Name | Text | No | Narrows a name search. |
| IDOC Number | Text | Conditionally required | Partial number searches need at least three digits. |
| Search / Reset | Buttons | n/a | Run the query or clear the form. |
The IDOC resident/client search image shows why that locator is a separate tool from Custer County jail custody.
Use IDOC when the person has moved into state prison, probation, or parole status, not as the first stop for a fresh Custer County booking.
Past Custer County Inmate Records
Released or older Custer County inmate records are not handled by a public county archive in the sources inspected. A past jail stay may need a written sheriff's public-records request, a court-record search in iCourt, or a judicial-record request through the Custer County court clerk. The right route depends on whether the user needs custody records, court charges, a hearing record, or state supervision data.
The sheriff's official public-records notice says requests to examine or copy sheriff records must be made in writing and should use the county form. It also says fees can apply for copies, redaction, time over two person-hours, overtime, photos, videos, thumb drives, and return shipping. Costs must be prepaid before release.
| Need | Best Official Route | Limits |
|---|---|---|
| Current custody | Custer County Sheriff's Office phone line | Physical housing may be out of county. |
| Booking or jail record | Sheriff public-records request | Fees, redaction, and pending-case limits can apply. |
| Court charges or hearing dates | Idaho iCourt or Custer County Courts | Sealed or exempt records may not appear. |
| Sentenced state custody | IDOC Resident/Client Search | Daily updates may still lag real-time status. |
Custer County Inmate Record Details
No official public Custer County roster profile was located, so no public county profile fields can be verified. Some information may exist in internal booking records or records released after review, while formal charges are best checked in court records after the prosecutor files them.
| Field | What the Research Supports |
|---|---|
| Booking number | Not observed in an official public Custer County roster profile. |
| Booking date or time | May exist in internal booking records, but no public online profile was found. |
| Charges | Booking allegations can differ from prosecutor-filed court charges in iCourt. |
| Bond | Call jail or court and check public court records where available. |
| Housing location | Must be confirmed because commissioner minutes document out-of-county housing. |
| Mugshot | Not observed online; Idaho law restricts sheriff release or publication of booking photos. |
Custer County Detention Facilities
The Custer County Facility Map contains one local detention facility. No separate city jail, work-release center, regional jail, state prison, BOP prison, or ICE detention facility was found in official sources within Custer County.
- Custer County Jail - the local county jail in Challis, operated by the Custer County Sheriff's Office for pretrial detainees, short local sentences, court holds, and transfers.
Custer County Inmate Population FAQ
How large is the Custer County inmate population?
The Idaho Sheriffs' Association directory lists Custer County Jail with an average daily population of 3 and a rated capacity of 8. That is a directory snapshot, not a real-time roster. Custer County commissioner minutes from October 14, 2025 also noted two inmates out of county.
Is there a public Custer County jail roster?
No official public Custer County jail roster was located in the county and sheriff sources inspected. Start with the sheriff's office, then use VINELink, iCourt, IDOC, BOP, or ICE depending on the custody stage.
Can a Custer County inmate be held outside Challis?
Yes. Official commissioner minutes recorded two inmates out of county in October 2025. That means the Custer County inmate population can include people tied to a Custer County case who are not physically in the local jail.
Where are Custer County court charges found?
Formal court charges are searched through Idaho iCourt or the Custer County court clerk. Jail booking allegations may change after prosecutor review, so court records are the better source for filed charges.
