Search Marquette County Jail Inmates

Marquette County Jail Overview

Marquette County Jail is operated by the Marquette County Sheriff's Office. It is the county jail, not a state prison, so its core population is made up of newly arrested people, pretrial detainees, people serving local jail sentences, and people in judge-ordered local release programs. The county also states that the jail may house a small number of federal inmates, which creates an important lookup split. A person held locally can be tied to the sheriff's custody process, while a sentenced state prisoner belongs in MDOC OTIS and a federal prisoner may require a BOP or U.S. Marshals search.

The official jail page describes the facility as a three-story building with housing blocks on each floor. Inmates are classified by the severity of their crimes, which means housing is tied to jail security and offense factors rather than a public preference or visitor request. The Sheriff's history material says the current jail was built in 1975. Sheriff Gregory S. Zyburt leads the Sheriff's Office, with Undersheriff Lowell A. Larson Jr. and Corrections Captain Brian H. Steede listed in county materials for agency leadership and jail administration.

The official Marquette County Jail services page shows the jail service information, capacity statement, and public counter rules.

The screenshot is useful because the jail's capacity, federal-inmate note, service window, medication rule, personal-item rule, and JailATM directions appear together on one county source.

Marquette County Jail Population

The county publishes a rated capacity for Marquette County Jail, but it does not publish a current official daily census dashboard in the research source. The official jail page lists the jail as an 80-bed facility and states that it may also house up to 10 federal inmates. A separate Prison Policy Initiative Census-related table lists a historical local count of 101 for Marquette Co. Jail, and a February 19, 2025 local news report described a recent high of as many as 103 total inmates against the 80-bed capacity. That news item should be treated as dated context, not a current roster count.

Marquette County Jail Lookup

There is no official browser-based Marquette County web jail roster documented in the research file. The county-specific lookup path uses the Marquette County Sheriff app after arraignment, the jail phone or service window for very new arrests, and records requests for older booking material. Before arraignment, the jail says it may release only whether the person is lodged and the bond amount. That limit is a rule about what staff can share, not proof that the person is absent from the jail.

1. For a very recent arrest, call the Sheriff's Office main line and ask whether the person is lodged and whether a bond amount is available.
2. For post-arraignment county jail custody, use the Marquette County Sheriff app inmate lookup rather than a state prison locator.
3. Use the exact legal name and any date of birth or court case information available to avoid matching the wrong person.
4. If the person was sentenced to state prison, search MDOC OTIS instead of the county jail channels.
5. If federal or immigration custody is possible, check the BOP locator, U.S. Marshals, or ICE ODLS as separate systems.

Marquette County Jail Contact

Use the jail and Sheriff's Office contact information for local custody status, service-window questions, bond deposit routing, and public counter access. The jail service window is open to the public except for three daily closure periods, and the county warns that other safety-related closures can occur. Public Sheriff's Office hours are Monday through Friday, 8 a.m. to 4:30 p.m.

Marquette County Jail Visitation

Marquette County Jail visitation uses SmartInmate accounts for video visits and scheduling. Visits must be scheduled at least 24 hours ahead. On-site public visits have no fee, and visitors who do not have internet access may use lobby terminals at the Sheriff's Office. General public visitors must be at least 18 and have picture identification. Children 17 and under are not allowed in the lobby during visitation. Food, drinks, packages, tobacco products, cell phones, and pagers are not allowed, and the jail conducts criminal-record checks that can deny visitors with warrants.

The official Marquette County Jail visitation page documents SmartInmate scheduling, on-site hours, visitor rules, and attorney or clergy visiting windows.

This page is the best source for the distinction between scheduled public visits and daily attorney or clergy access.

Marquette County Jail Mail

Regular Marquette County Jail mail does not go straight to the jail address. The county uses Smart Communications and MailGuard for regular postcards, letters, and greeting cards. Mail is processed off site and delivered to password-protected kiosks or tablets. Legal, court, clergy, and package mail are the exceptions, and those categories still use the jail address. SmartInmate is also used for electronic messages.

Marquette County Jail Intake

Booking at Marquette County Jail begins after a local, state, or other law-enforcement agency brings a person to the facility. The county does not publish a full booking script, but the documented flow is arrest, transport to the jail, intake, classification, court handling, and housing or release. District Court handles first appearances, preliminary examinations on felony cases, and bail setting and acceptance. That means jail custody and court records often develop on related but separate tracks.

Medical and property rules are strict. Prescription medication for a pre-existing condition may be accepted only in its original container and only after verification by the jail health-care provider. Mixed medications are not authorized. The jail does not accept personal items for people housed at the main jail except court-ordered personal clothing for a jury trial. Hygiene items are provided by the jail or can be purchased through commissary.

Classification

The jail process for assigning housing and supervision based on severity of offense and custody factors.

Arraignment

The first formal court stage where charges, rights, and bond conditions may be addressed.

Work release

A judge-ordered program that can let an approved inmate leave jail for work on an approved schedule.

Marquette County Jail Programs

Marquette County Jail publishes more program detail than many county jails. Adult Ed and GED programming is connected to Marquette Community Schools Adult Education, with a certified teacher from Marquette Area Schools visiting twice weekly for two-hour sessions. The inmate worker program screens offenders before assigning tasks such as kitchen or laundry work. Religious services are available when staffing permits, and AA is typically run by approved volunteers. Thinking Matters is offered on Tuesdays for recidivists or high-risk inmates to work on decision-making skills.

The Sheriff's Release Program covers work release, school release, and treatment release when ordered by the presiding judge. Work release allows an approved inmate to maintain employment in the community on an employer-provided and jail-approved schedule. The documented work-release cost is $25 per day. Housing reimbursement is separate: the county bills $60 per day after incarceration for housing reimbursement, while medical and mental-health service costs are billed immediately regardless of legal status.

The Sheriff's Release Program page shows the county's work, school, and treatment release rules and the daily work-release cost.

The image supports the distinction between court-ordered release programming and ordinary bond, which are not the same thing.

Marquette County Jail Transfers

A Marquette County Jail search should not stop at the jail if the person has moved to another custody system. Sentenced adult prisoners in Michigan Department of Corrections custody should be searched through OTIS, and OTIS does not include county jail or city lockup inmates. Federal custody is also separate. The jail may house up to 10 federal inmates, but BOP custody, U.S. Marshals pretrial custody, and ICE detention are different systems with different locators.

For broader custody searching, the Marquette County Jail record can be compared with court records and the state prison locator. The Marquette County jail inmate records page gives the broader channel chain for app lookup, phone status, FOIA, OTIS, BOP, ICE, and Michigan VINE.
