St. Clair County Intervention and Detention Center Inmate Lookup

St. Clair County Intervention and Detention Center Overview

The St. Clair County Intervention and Detention Center / St. Clair County Jail is operated by the St. Clair County Sheriff's Office. Sheriff Mat King is the elected sheriff, and the county administration page names Jail Administrator Tracy DeCaussin for the jail-specific chain. The facility is at 1170 Michigan Road, Port Huron, MI 48060, on the public-safety campus that also houses Central Dispatch and other sheriff functions. It is not the downtown courthouse at 201 McMorran Boulevard.

This is a county-jail facility. It holds local adult detainees after arrest, pretrial defendants waiting for district or circuit court proceedings, sentenced county-jail inmates, trustees drawn from sentenced inmates, and people held under other-agency or immigration arrangements when accepted. ICE lists St. Clair County Jail as a Detroit Field Office detention location, but that does not make ICE ODLS the main roster for ordinary local custody. The official St. Clair County Sheriff's Office inmate lookup remains the starting point for current local jail custody.

St. Clair County Jail Capacity and Population

The St. Clair County 2023 Master Plan identifies the Intervention Center at 1170 Michigan Road and describes a jail with 448 adult beds. The same campus description includes 70 juvenile beds, offices, Central Dispatch, classrooms, and other county functions. The research file did not locate an official current live inmate count on the public lookup search page, so the capacity number should not be treated as today's population.

Other high-authority population references exist, but they are not a live official county count. The Prison Policy Initiative phone-rate appendix lists St. Clair County Jail with an average daily population figure of 560, and a Prisoners of the Census table lists a local correctional population entry of 498 dated December 31, 2013. Those figures can provide historical context, but the county roster should still be used to confirm whether a specific person is currently in local custody.

How to Look Up an Inmate at St. Clair County Intervention and Detention Center

For this county jail, use the official St. Clair County Sheriff's Office Inmate Lookup at inmates.stclaircounty.org, which the county links from the Intervention and Detention Center page. The public form accepts Last Name, First Name, and Booking Number. The research captured a validation message stating that either a last name or a booking number is required, which means first name is a narrowing field rather than a standalone search key.

1. Open the official St. Clair County Sheriff's Office inmate lookup.
2. Enter the last name, or enter the booking number if it is known.
3. Add the first name to narrow common surnames, spelling variations, or duplicate results.
4. Compare the result with the jail information desk if timing, bond, release, or identity is uncertain.

The lookup is updated periodically throughout the day, but it is not guaranteed to be real-time, complete, or a historical archive. If a person is not found, check the custody type before assuming release. Use MDOC OTIS for sentenced Michigan prisoners, the BOP locator for federal inmates, ICE ODLS for immigration detainees, and Michigan VINELink for custody or release notifications where available.

St. Clair County Intervention and Detention Center Address and Contact

Use the Michigan Road jail campus for custody questions, jail visits, inmate money, sheriff FOIA requests, and jail information. Court hearings, prosecutor business, and many court records are tied to McMorran Boulevard or online court portals instead. For public-record requests to the Sheriff's Office, the research identifies the sheriff FOIA form at stclaircounty.org/Uploads/Sheriff/Forms/FOIA Request Form.pdf.

Visiting Someone at St. Clair County Jail

Visitation and communication are handled through InmateSales and the InmateSales app. Visitors create an account, wait for approval, and then schedule visits or receive inmate phone calls. Visitors must have picture ID. Children under 17 must be accompanied by a parent or legal guardian and must bring a birth certificate. Only processed-in visitors may visit, only three people are allowed per visit including children, and non-attorney visits are monitored and recorded.

Mail, Phone, and Money at St. Clair County Jail

Mail rules changed on May 15, 2026. Standard non-legal family and friend mail is no longer addressed to the jail campus. Legal mail still goes to the Michigan Road facility. Standard mail that does not meet the listed guidelines can be destroyed or rejected, so use the exact address format and include the inmate name and inmate ID when available.

Money can be dropped off in the lobby Monday-Friday from 8:30 a.m. to 4:30 p.m. Do not send cash through the mail. Commissary ordering is pod-based: A and B pods order Tuesday, C and D pods Wednesday, E and F pods Thursday, and G pod Friday. Orders are placed by tablet, must be placed by Sunday at 11:00 p.m., and only one order per inmate is filled.

Medical, Notary, and Copy Fees

Medical and dental costs are charged to the inmate trust account under the jail's published rules. Requests for medical or dental needs are made through the tablet, while emergency medical requests should be brought to the on-duty correction officer. A private physician or second opinion requires arrangements for the physician to come to the jail, and reimbursement is the inmate's responsibility.

Booking, Classification, and Property at St. Clair County Jail

At admission, booking officers take all inmate money and deposit it into an inmate trust fund. Personal property is confiscated, inventoried, signed for, and returned at discharge. Jewelry is not permitted except a wedding ring if worn at booking, and inmates cannot keep money in the living area. If a person is transferred to another facility, property is stored for only 30 days. Property is not released while the inmate remains in custody unless special circumstances are reviewed by the on-duty supervisor.

Classification occurs for inmates confined more than 72 hours. Staff interview the inmate and assign general population unless extraordinary conditions require an exception. During classification, staff explain the purpose of classification and visiting hours, answer reasonable questions about rights and privileges, discuss programs and services, and provide tablet access to inmate rules and regulations. This local 72-hour timeline is important because a new arrestee may pass through intake before standard housing, tablet, and program procedures fully apply.

Programs, Services, and PREA Reporting

St. Clair County's jail programs are request-driven. Inmates interested in programming or services send a kite through the tablet, and court-ordered participants receive priority placement. General population programming includes Life Skills, Alcohol and Drug Education, Anger Management, Domestic Violence, Parenting, Thinking Matters, Trauma Group, and PTSD Group. The RSAT program is the most intensive jail-based substance-use-disorder program listed and requires a court order.

Additional services include Narcotics and Alcoholics Anonymous meetings, Peer Recovery, Medication Assisted Treatment, re-entry case management, community resources and referrals, reading material, spiritual counseling, religious groups, church services, GED and diploma services, high school completion, adult basic education, tutoring, and mental-health services. The jail also has a Judicial Sentence Reduction Program for eligible sentenced inmates: one petition per sentence, sentence of 60 days or more, 50% served first, and a possible 25% reduction if the process is approved by the proper offices and judge.

The St. Clair County Intervention Center has a zero-tolerance PREA standard toward sexual abuse or assault attempted or committed against any inmate or detainee. Citizens may report sexual abuse or harassment by calling central dispatch non-emergency at (810) 985-8115, and anonymous reports are allowed. The PREA protocol includes special referral paths for allegations involving ICE detainees, including Joint Intake Center, ICE OPR or DHS OIG, and the ICE Field Office Director where appropriate.

OTIS, BOP, ICE, VINELink, and Sheriff App Fallbacks

The county roster is correct for current local jail custody, but it is not the right system for every custody status. MDOC OTIS covers prisoners, parolees, and probationers under Michigan Department of Corrections supervision and discharged offenders within three years; it does not cover county-jail-only inmates or people arrested but not yet sentenced. The BOP locator covers federal inmates from 1982 to present and does not provide a county-style mugshot gallery. ICE ODLS is the immigration detainee locator, and it is relevant because ICE identifies St. Clair County Jail as a detention location under the Detroit Field Office.

Michigan VINELink is available for custody and release notifications. The St. Clair County Sheriff MI mobile app is also available through Google Play and the Apple App Store. The app-store description advertises crime reporting, tips, interactive features, public-safety news, and information. A public review referenced inmate lookup, but official app-store text did not confirm a warrant-search feature, so the website roster remains the verified main lookup path.
