Search the Idaho County Inmate Population

The Idaho County inmate population is split between local jail custody in Grangeville and state prison custody in Idaho Department of Correction records. The Idaho County inmate population includes current jail detainees, people serving short county sentences, and some inmates awaiting state placement, while sentenced state residents are tracked through a separate locator. A useful Idaho County inmate search starts with the county's current list, then moves to court, state, federal, or notification tools when the jail page does not show the person. The Idaho County inmate population is small, but the search path has several distinct systems.

Idaho County Inmate Population Snapshot

The official local count starts with the Idaho County Jail Division. That county page reports a small sheriff-run jail, built in 1954, with one chief jailer and seven detention officers. It states that the jail houses male and female inmates, lists a maximum of 11 individuals, and reports an average daily population of 18 inmates. Those figures matter because they come from the same county source and show why the Idaho County inmate population cannot be read only as a daily roster count.

Idaho County, Idaho also has a state prison inside the county line. North Idaho Correctional Institution in Cottonwood is run by the Idaho Department of Correction, not by the sheriff. It has an operating capacity of 428 male residents and mainly serves retained-jurisdiction cases. Those residents are part of the state prison population, not the local jail roster, even though the facility is physically in Idaho County.

Idaho County Inmate Population Statistics

Published Idaho County inmate population figures are narrow but useful. The county jail page gives capacity, average daily population, staffing, cost, and local sentence range. The county's PREA annual report gives one annual throughput point for 2018. IDOC gives the state prison capacity for NICI and a fiscal-year population note for retained-jurisdiction riders. No official county source in the research set published a full demographic split by race, age, sex count, charge level, or average length of stay.

The 2018 booking and release counts show turnover. A jail can have a modest average population and still book many people across a year. That distinction is central in Idaho County because the public roster only shows people listed at a given moment, while annual bookings include people who may have bonded out, finished a short sentence, transferred, or moved into court and state systems.


Idaho County Jail Capacity

The county's own numbers put the Idaho County inmate population in a tight local setting. The jail page reports a maximum of 11 individuals and an average daily population of 18. That wording should be read with care because the county does not label the comparison as a formal overcrowding finding. Still, the same official source publishes both numbers, and the result is clear enough for users who are trying to understand why beds, transfers, visiting rules, and bond timing may matter in a small jail.

The county also published a 2022 request for qualifications for a new Jail/Sheriff's Office Complex. The planning scope asked firms to consider a 30 to 50 bed jail, command center, possible regional dispatch center, sheriff administration, licensing functions, and attorney-client or interview conference rooms. That RFQ is a planning source only. The current jail page still identifies the 1954 facility and the small capacity, so the safer reading is that Idaho County had studied a larger jail complex rather than that a new jail had opened.

Who Is in Idaho County Custody

The Idaho County Jail holds people charged with state or local offenses, county-sentenced inmates, people serving time, people awaiting sentencing, and inmates awaiting IDOC placement when that status appears on the current list. The public list has included plain-language status terms such as Arrest Warrant, Probation Violation, Awaiting Sentencing, Serving Time, and Sentenced to IDOC. Those labels are custody clues, not full court records.

NICI has a different population. IDOC describes it as a program-specific prison at a former military radar station north of Cottonwood. It primarily houses male residents sentenced under retained jurisdiction. Retained jurisdiction is an Idaho sentencing path where IDOC programming and evaluation can help a court decide whether a person may be a viable probation candidate. A person in that state process should be searched through IDOC, not through the Idaho County current list.

Idaho County Jail Records Laws

Idaho jail and court access starts with public-record law, but the law does not make every detail public at all times. Idaho Code Section 74-102 gives a right to examine and copy public records unless another statute provides an exemption. Section 74-105 covers law-enforcement and investigatory exemptions, which can matter while a case is pending.

Key Idaho statutes:

Idaho Code Section 74-103 governs how agencies respond to public-records requests.

Idaho Code Section 20-601 sits in the county-jail law framework.

Idaho Code Section 20-607 supports the local prisoner reimbursement note on the jail page.

Idaho Code Section 18-5210 is the contraband law cited in IDOC visiting materials.

The Idaho County Records Division says written requests are required before reports can be released to the public. It also warns that some Sheriff's Office information cannot be accessed while cases are pending adjudication through the courts. For jail population and inmate lookup work, that means the roster is the first stop, but not the only records path.




Idaho County Inmate Record Fields

Idaho County publishes a current list, not a detailed profile database. The visible record is enough to confirm a public custody listing and get a rough charge or status clue. It is not enough to confirm full statutes, court case numbers, court dates, booking time, housing unit, or release date. For those details, use the court portal, the jail phone line, or a written records request.

County Jail or State Prison

Many Idaho County inmate population searches fail because the user is checking the wrong system. The county jail list is for current local custody. The IDOC locator covers state prison, probation, and parole records. BOP and ICE are separate federal systems. VINELink is notification-centered and should not be treated as a complete booking archive.

Idaho County Court and Bond Records

Jail roster text is not the same as a court charge. After an arrest, the Idaho County Prosecuting Attorney reviews law-enforcement reports and decides what charges to file. Formal court records are searched through the Idaho iCourt Portal or requested from the Idaho County District Court clerk. The court and jail share the 320 West Main Street courthouse area in Grangeville, while the prosecutor is nearby at 416 West Main Street.

Bond should also be verified through official channels. The roster may show a dollar amount or None, but None can appear with sentenced, warrant, probation, or other hold statuses. Idaho County jail materials say credit-card bond or payment questions go through the District Court Office during business hours, and the Sheriff's Office or jail cannot take credit-card information. Court records after filing are covered on the Idaho County court records after jail arrest page.


Idaho County Records Requests

The Idaho County Sheriff's Office Records Division is the fallback when the public roster does not show a booking, arrest report, incident report, or copy of a booking record. The records page names Records Clerk Mandee Mignerey and says reports cannot be released without a written request. The county public-records form asks for name, date, contact information, a specific record description, date range, location, copy or inspection choice, and a certification that records will not be used for a barred mailing or phone-list purpose.

The county form lists Idaho County, 320 W. Main Street, Room 5, Grangeville, ID 83530, phone 208-983-2751, and Monday through Friday 8:30 AM to 5:00 PM for county records access. It also contains a residency declaration and fee schedule. The form's printed response timing should be checked against current Idaho Attorney General guidance because state response windows changed after some older forms and summaries. For a jail record, describe the Sheriff's Office or jail record sought, the person's name, date of arrest or booking if known, and any court case number.


Idaho County Detention Facilities

The Idaho County inmate population map has two facility pages. The first is the sheriff-run county jail in Grangeville. The second is NICI, a state prison in Cottonwood. They are both in Idaho County, but they answer to different agencies and use different lookup systems.

  • Idaho County Jail - sheriff-operated local jail for current county custody, short county sentences, warrants, pending court matters, and some inmates awaiting IDOC placement.
  • North Idaho Correctional Institution - IDOC state prison for male retained-jurisdiction residents and other state custody managed through the IDOC locator.

Idaho County Jail Visits

Idaho County's jail pages give a useful but conflicting weekday visitation schedule. The Jail Division page lists Monday through Friday 10:00 AM to 4:00 PM and Saturday 3:00 PM to 6:00 PM. The Jail FAQ lists Wednesday and Friday 1:00 PM to 4:00 PM and Saturday 3:00 PM to 6:00 PM. Both sources say an inmate must be in Idaho County custody for five days before visits are allowed. Call 208-983-1123 before traveling.

Directions to the Idaho County Jail

Idaho County Jail and the Sheriff's Office are in the courthouse complex area in Grangeville, the county seat. Official sheriff and jail pages use the same 320 West Main Street address as the courthouse, so visitors should confirm the right public entrance before arrival. From the U.S. 95 corridor, use the downtown Grangeville and Main Street approach. From Cottonwood or the NICI area, travel toward Grangeville and enter the courthouse block from the same Main Street corridor.
