Olmsted County Inmate Population Today
The Olmsted County inmate population is reported through several public sources, not through one single data file. The Sheriff's Office operates the Olmsted County Adult Detention Center, known locally as the ADC, and identifies it as a direct-supervision jail with a rated capacity of 202 beds. The county also operates the Olmsted County Work Release Facility for court-ordered work release, Sentenced to Service, and minimum-security detainees. Together, those two local facilities explain why an Olmsted County custody search may include a new arrest, a sentenced misdemeanor term, a work-release placement, or a hold for another agency.
Population data and roster data answer different questions. The annual reports and PREA data show trends in average daily population, admissions, and facility use. The daily ADC In Custody List shows who is held at the jail on a given day. The county roster can include pre-sentenced adults, sentenced adults, boarders, work-release-related detainees, and people housed for federal, state, or county agencies when space is available. A sentenced felony case usually leaves the county jail count once the person is committed to the Minnesota Department of Corrections.
Olmsted County Inmate Population Statistics
The strongest county figures come from the Sheriff's Office annual reports, ADC overview, PREA data, and the facility map research. The 2025 Sheriff's Office annual report, tabulated in January 2026, listed 171,783 citizens across 18 townships, eight cities, and 653 square miles. It also reported 197 Sheriff's Office employees, with about 100 assigned to ADC functions and 97 assigned to the Law Enforcement Center. Those staffing and geography figures matter because the jail serves Rochester, contract cities, townships, other agencies, and court-ordered detention needs.
The ADC average daily population rose from 108.94 in 2023 to 121.42 in 2024 and 122.98 in 2025, according to the 2025 Sheriff's Office annual report trend table. The 2025 figure was below the 202-bed rated capacity, but bed count alone does not describe daily operating pressure. The research notes Minnesota DOC inspection concerns about practical space limits such as laundry and court-holding areas, so population should be read with facility function, classification, gender separation, program needs, and court movement in mind.

Olmsted County Jail Population Trends
The Olmsted County jail population increased sharply after 2021. The average daily population was 75.66 in 2021 and reached 122.98 in 2025. That rise does not mean every day reached capacity, and it does not prove that any one policy caused the change. It does show why current roster checks, annual population data, and court status should be kept separate. The daily custody list is a roster snapshot. Annual reports show the workload over time.
Gender totals in the county data are limited to male and female average daily population. Publicly captured sources did not publish race, age bands, average length of stay, pretrial percentages, or felony-versus-misdemeanor population tables. Those gaps should not be filled by guesswork. When a needed breakdown is not online, the county's Data Practice Request process is the correct public-record route.
| Year | Average Daily Population | Notes |
|---|---|---|
| 2021 | 75.66 total | PREA data collection form |
| 2022 | 90.52 total | Sheriff 2024 report and PREA data |
| 2023 | 108.94 total | Sheriff 2025 report |
| 2024 | 121.42 total | Sheriff 2025 report |
| 2025 | 122.98 total | Sheriff 2025 report |
Laws for Olmsted County Inmate Records
Minnesota law explains why many Olmsted County jail records are public, and why some fields are withheld. The Minnesota Government Data Practices Act starts with the rule that government data is public unless another law classifies it differently. A requester may inspect public data without a fee, while copies may carry statutory or actual costs. For jail records that are not on the ADC roster, Olmsted County's online data request process is the local path.
Law-enforcement and detention records have their own sections. Minnesota Statutes section 13.82 covers law-enforcement data and says booking photographs are public data unless access is temporarily withheld because release would harm an active investigation. Section 13.85 covers corrections and detention data created because of lawful confinement. Section 241.021 gives the Department of Corrections licensing and inspection authority, including death-in-custody reporting requirements. Minnesota Rules chapter 2911 sets jail standards for administration, supervision, staffing, and custody conditions.
Public-record point: Olmsted County jail data can be public and still incomplete online. Medical, juvenile, security, investigative, and private data may be redacted or withheld.
Search Olmsted County Inmates
The official current-custody source is the Olmsted County ADC In Custody List. The county's Who is in Custody? page points users to that list and gives the ADC phone line as 507-328-6790. The roster is free and does not require a login. It is updated daily, so it is useful for routine checks but should not be treated as a real-time court certificate.
On June 18, 2026, the research capture showed the roster timestamp as in-custody detainees through June 17, 2026 at 10:59:51 p.m. That timestamp is important for a very recent arrest or release. If the person was booked after the daily update, released before the page changed, moved on a warrant, or transferred to another agency, the public list may lag. Call the ADC when custody status affects court, bail, travel, or family contact decisions.
- Open the county custody page or go directly to the ADC In Custody List.
- Check the update timestamp before relying on the list.
- Type the person's first or last name, or choose the first letter of the last name.
- Review each matching inline roster entry for booking date, photo date, reason, status, and charges.
- Call the ADC at 507-328-6790 if the person is missing, newly arrested, or possibly released.
| Roster Field | Type | Required | Notes |
|---|---|---|---|
| First or last name search | Text search | Unspecified | The roster language says users may type the person's first or last name. |
| Last-name initial | Alphabet filter | No | A through Z initial links are available. |
| Search buttons | Not exposed in text capture | Not applicable | The captured page functioned as type-to-filter plus alphabet selection. |
Olmsted County Inmate Record Details
Olmsted County's public roster is photo-and-charge oriented. It shows enough to confirm that a person is listed in custody, but it does not publish a full booking packet. The roster entries observed in research included the person's booking photo, photo date, name, booking date, incarceration reason, detainee description, charges, and charge levels. It did not show bond amount, housing unit, court date, date of birth, home address, warrant number, or arresting agency in the captured public text.
That limited field set affects where a search should go next. The roster can show a status such as New Charges, Warrant Arrest, Writ, Pre-Trial, Sentenced, Probation Violation, Release Revoked, Other Agency Hold, or US Marshall's Hold. Bond and court dates should be verified through court or jail channels. Formal court charges may change after prosecutor review, so use MCRO and court administration for the court case after checking custody.
| Field | What It Shows |
|---|---|
| Mugshot / photo | A public booking-style image appears inline for listed detainees. |
| Photo date | The roster displays a separate timestamp for the photo. |
| Booking Date | The date and time the person was booked into ADC custody. |
| Incarceration Reason | Status category such as New Charges, Warrant Arrest, Writ, Pre-Trial, Sentenced, or Probation Violation. |
| Detainee Description | Phrase such as Awaiting Arraignment, Awaiting Bail or Bond, Release Revoked, Other Agency Hold, or US Marshall's Hold. |
| Charges and Level | Numbered charge descriptions with levels such as Felony, Gross Misdemeanor, Misdemeanor, or Petty Misdemeanor. |
Olmsted County Custody Sources
The county's ADC overview is the source for the 202-bed capacity, direct-supervision description, and the link between the jail and work-release operations.
The overview is most useful for capacity and facility role. The daily custody list is still the better source for finding a current person in custody.
The county's Who is in Custody? page connects the public to the ADC custody list and the published jail phone line.
That page is the practical bridge between a web roster search and the ADC phone fallback when timing or release status matters.
County Jail vs State Prison
The Olmsted County inmate population is not the same as the Minnesota prison population. The county roster covers people held at the ADC and work-release operation. The Minnesota Department of Corrections locator covers adults committed to the Commissioner of Corrections who remain under DOC jurisdiction, including people in prison and people released from prison but still on DOC supervision. A person sentenced in Olmsted County can leave the ADC roster before appearing in MNDOC, because the state locator may take several business days to reflect a new commitment.
| Custody Type | Primary System | Use It For |
|---|---|---|
| County jail custody | Olmsted County ADC In Custody List | Current ADC detainees, new bookings, short sentences, warrants, holds, and local custody status. |
| State prison custody | Minnesota DOC public locator | Adults committed to MNDOC and still under state corrections jurisdiction. |
| Federal sentenced custody | BOP Inmate Locator | Federal inmates from 1982 to present and federal prison facility information. |
| Immigration detention | ICE Online Detainee Locator | Current ICE custody, or CBP custody over 48 hours, by A-number or biographical data. |
The ADC roster can show a federal hold, such as a US Marshals hold, if the person is housed locally before federal transfer or sentencing. That does not make the ADC a federal prison. It means Olmsted County is housing the person for another agency at that point in the custody chain.
Olmsted County Detention Facilities
Two local detention facilities serve the Olmsted County inmate population. The ADC is the primary jail and roster source. The Work Release Facility is a distinct minimum-security location tied to court-ordered work release and on-site video visitation. No Minnesota DOC adult prison, BOP prison, or ICE detention center was located in Olmsted County in official source checks.
- Olmsted County Adult Detention Center - The main county jail in Rochester, holding pre-sentenced adults, sentenced adults, boarders, work-release-related detainees, and agency holds when space is available.
- Olmsted County Work Release Facility - A minimum-security facility for court-ordered work release, Sentenced to Service, and minimum-security detainees.
Olmsted County Booking to Court
A local arrest usually moves from transport and booking at the ADC to the public custody-list entry, prosecutor review, formal charging, and a district court case. The roster displays booking-level charges and custody descriptions. The formal court record is in Minnesota district court and may differ if the prosecutor amends, adds, declines, or dismisses charges. The Olmsted County Attorney prosecutes adult felonies, lesser crimes outside Rochester and in contract cities, and juvenile matters. Rochester City Attorney handles petty misdemeanors, misdemeanors, and some gross misdemeanors occurring in Rochester.
For court records after a jail arrest, use Minnesota Court Records Online. Pending criminal, traffic, and petty misdemeanor cases without a conviction may not return by defendant name in MCRO, so case-number searches and court calendar checks can matter. For custody and booking data, use the ADC roster or records request. For public conviction history, use the BCA criminal history search.

- Minnesota Court Records Online, the statewide district court case-search system.
Olmsted County Records Requests
When the roster does not answer the question, use Olmsted County's Data Practice Request instructions or the online data request form. A public request should clearly describe the booking record, jail data, mugshot, or other public data sought. It may state that the request is made under Minnesota Statutes Chapter 13. County guidance says the public cannot be required to identify themselves or explain why they want public data, although contact information may be needed if copies must be sent.
Requests for data about oneself, a minor child, or a person under guardianship are handled differently. Olmsted County requires proof of identity, and requests that are not made in person require notarized or certified copies of required documents. Inspection of public data is free. Copies may carry fees. Redactions can apply for juvenile, medical, security, private, confidential, investigative, or nonpublic information.
