Osceola County Jail Overview
Osceola County Jail is operated by the Osceola County Sheriff's Office. The official facility name used by the roster is Osceola County Jail. It is the only active detention facility located for this county in official sources, and it serves local jail custody for Osceola County rather than state, federal, or immigration detention. The jail holds local detainees, people serving county jail sentences, court-ordered jail time, work-release participants, and short-term local arrestees.
The Sheriff's Office is led by Sheriff Kevin Wollmuth, and the official staff page lists Nathan Rosenberg as Jail Admin. The county sheriff page says the sheriff maintains and operates the county jail, along with law-enforcement, civil, 911, permit, and public-safety duties. For Osceola County Jail custody, that makes the sheriff's office the local source for current status, jail rules, roster questions, mail, phone service, visitation, commissary, work release, medical costs, and public-record requests.
Osceola County Jail Capacity
The current rated capacity for the pre-remodel Osceola County Jail was not located in official web sources, so it should not be filled in by guesswork. Official construction material does give firm building facts. The October 2024 bid letting for the Osceola County Public Safety Center Remodel describes partial renovation of the Sheriff's Department, E-911, and support areas, plus a new 14-bed jail addition with support areas and future expansion capability to 36 beds through bid alternates.
The inspected current roster PDF contained six named entries for the 6/1/2026 to 6/10/2026 date range, including released and unreleased entries. That is a roster count for one file, not an official average daily population. A supplemental 2022 phone-rate appendix listed Osceola County Jail with Reliance Telephone and an average daily population of four, but that is not an official county publication. The safest facility summary is therefore capacity planning from official bid documents, plus a clear note that no current official average daily population table was found.
Osceola County Jail Roster Lookup
The correct local lookup tool is the official Osceola County Sheriff current inmates page. The jail does not publish a searchable live database in the inspected source. Instead, it posts date-range PDF rosters. The roster is free and does not require a login, but it must be read manually because there is no public search form, profile page, export, filter, sort control, or pagination control on the county roster page.
- Open the sheriff current inmates page and select the current inmate roster PDF.
- Read the PDF list manually for the person's full name and arrest date.
- Check the release field and bond line to see what the roster reported for that period.
- If the person is not listed, check prior-month PDFs or call the jail at 712-754-2556.
- Use the Iowa DOC, BOP, or ICE locator only if the person may be outside county jail custody.
The roster page screenshot from the official current inmates page shows the PDF-based lookup format.
The image is useful because it shows the actual access channel: date-range PDFs, not a live inmate search form.

Osceola County Jail Contact
Osceola County Jail is on the public-safety and courthouse block in Sibley, near the Osceola County Courthouse. Official construction material references the area from 3rd Avenue looking east, and county access notices describe courthouse parking changes during the jailhouse project. No official public-transit route to the jail was located in the inspected sources. Visitors should confirm parking, accessible entry, and jail lobby access before traveling because construction can change routes around the block.

Visiting Osceola County Jail
The official Osceola County Jail information page publishes Sunday-only visitation. Visitors must be registered on the inmate's visitation list and must show identification. The jail may search visitors for contraband, and a visitor who refuses a required search may be denied admission. Visitation is a privilege for inmates and visitors, so rule violations can lead to loss of the visit.
| Category | Schedule or Rule | Type |
|---|---|---|
| Men's visitation | Sundays, 1:00 PM to 3:00 PM | In person |
| Women's visitation | Sundays, 3:00 PM to 4:00 PM | In person |
| Visitor list | Visitor must be on the inmate's list | Entry rule |
| Identification | Some form of ID is required | Entry rule |
| Video visitation | No official video visitation vendor located | Do not assume availability |
Note: Confirm the visit before traveling because jail schedules, lockdowns, court movement, construction access, and inmate discipline can affect visitation.

Orders have a posted minimum subtotal and a weekly order deadline for Friday delivery. No incoming calls are allowed for inmates, and calls are collect or at the user's expense.
The Tiger Commissary Osceola County facility page is the matched vendor source for commissary access.
The vendor screenshot supports the facility-specific commissary link, while the sheriff's jail rules control the local minimums and delivery deadline.
The Reliance Telephone Osceola County Jail facility page confirms the phone-service facility listing.
The Reliance page should be used for phone-service access, while the jail rules remain the source for local phone limits and calling-card availability.

Booking at Osceola County Jail
Local booking begins after an arrest, court commitment, or scheduled jail sentence. The person is brought into Osceola County Jail when local jail custody is required. Scheduled jail time must be arranged with the Osceola County Sheriff's Office before serving time, and work-release conditions must be arranged before admission. Once intake is complete, the public online record depends on the sheriff's weekly PDF roster practice, not on an instant public booking profile.
Sentenced Osceola County inmates are charged for their jail stay. The official jail information page says fees are collected at intake unless prior arrangements have been made with the jail administrator. If a sentence includes credit for time already served, the inmate is still required to pay the full amount for the total days sentenced. Medical services are provided regardless of financial situation, but inmates are liable for most medical costs, and new deposits may be applied to medical debt.
| Fee or Program | Official Detail |
|---|---|
| Sentenced Osceola County inmates | $50 per day. |
| Other jurisdiction or work release | $80 per day. |
| Work release | Must be arranged before admission and remains a privilege. |
| Grievance deadline | Written grievance to jail administrator within 48 hours. |
| Grievance response | Jail administrator response within 72 hours. |
A work-release violation can lead to an immediate five-day suspension, and the sheriff can recommend that the County Attorney petition the sentencing judge for permanent cancellation. The Veterans Justice Outreach Program is also listed for justice-involved veterans, with the Sioux Falls VA Health Care System contact at 605-336-3230 ext. 7762 or 800-316-8387 ext. 7762.
About Osceola County Jail
The official Public Safety Center Remodel materials give building context for the jail. The project includes partial renovation of the Sheriff's Department, E-911, and support areas, plus a new 14-bed jail addition with support areas. The bid letting describes approximately 7,182 square feet attached to the existing sheriff offices, E-911, and support areas, with future expansion capability to 36 beds through alternates.
County construction updates in 2025 also affected courthouse and jail-area access. The county said west parking was consumed by construction, short-term street parking was available around the courthouse block, the south courthouse entry was temporarily reopened without handicap accessibility, and the north door remained the handicap-accessible entrance. Permanent post-construction visitor parking instructions were not located in inspected official sources.
Osceola County Jail is the county custody point, but not every person with an Osceola County case remains there. A person sentenced to Iowa prison moves into Iowa Department of Corrections custody and should be searched through the Iowa DOC Offender Search. A federal prisoner should be searched through the BOP inmate locator. An immigration detainee should be searched through the ICE Online Detainee Locator System. Custody notifications are available through VINELink Iowa and the sheriff VINE page.
Note: Confirm current custody, parking, accessible entry, and visitation with Osceola County Jail before traveling to the facility.
