Search the Union County Inmate Population

Union County Inmate Population Overview

The official Union County Detention Center page is the main local source for the Union County inmate population. It describes a detention campus at the county level, not a state prison or federal jail. The county says the Pretrial and Work Camp Divisions supervise an average population of county and city detainees, including people awaiting court, people serving short sentences from Summary Court or General Sessions, and people serving Family Court sentences. That mix matters because a person on the jail roster may be waiting for bond court, serving a brief local sentence, or being held for another agency.

The same county material separates the main detention center from the Union County Detention Center Prison Work Facility. Both operate from the Jonesville Highway campus, but the work facility has a distinct role for state inmate workers and county work details. No official South Carolina Department of Corrections prison, BOP prison, ICE detention center, or regional jail was located in Union County during research. Sentenced state prisoners from Union County move into the SCDC incarcerated-inmate search once state custody becomes the main system.

Union County Inmate Population Statistics

Union County publishes a few strong jail statistics, but it does not publish a full annual jail report in the sources inspected. The most useful official figure is the average county/city detainee population published on the detention-center page, inspected June 29, 2026. The county also gives the number of officers assigned to the Pretrial and Work Camp Divisions and states how many state inmate workers the Prison Work Camp can house. Rated bed capacity, annual bookings, average length of stay, and demographic tables were not located in official county sources, so they should not be inferred from the roster.

Union County Inmate Population Trends

The available trend record is thin. The county source gives a standing average population figure, and the roster API sample from June 29, 2026 returned a time-sensitive total record count. Those two numbers are useful, but they are not the same thing. The county average is an official operating figure. The portal result is a snapshot of public roster rows at one moment and can change as bookings, releases, holds, and transfers occur.

Several local processes can move the Union County inmate population up or down. New arrests and warrants add bookings. Twice-daily bond hearings can lead to release, a no-bond hold, or continued detention. Short county sentences stay local, while state prison sentences shift the lookup path to SCDC. Holds for probation, SCDC, ICE, US Marshals, or another jurisdiction can keep a person in the jail even when a local bond is posted.

Who Is in Union County Jail

The Union County inmate population is not just one group. Official county text names pretrial detainees, county and city detainees, people serving sentences of 90 days or less from Summary Court or General Sessions, and Family Court sentences. The portal also includes held-for-agency options for the Union County Sheriff's Office, Union Public Safety Department, Jonesville Police Department, SCDC, Probation, Parole and Pardon, ICE, US Marshals, SLED, South Carolina Highway Patrol, Family Court, and outside agencies.

• Pretrial detainees: people booked after arrest while charges, bond, and first appearance move through court.
• Short local sentences: people serving qualifying Summary Court or General Sessions sentences of 90 days or less.
• Family Court sentences: custody tied to Family Court authority rather than a new General Sessions conviction.
• State inmate workers: sentenced state inmates assigned to work-camp duties at the county detention campus.
• Outside-agency holds: custody blocks for SCDC, probation/parole, ICE, USMS, or another jurisdiction.

Race, sex, and age appear as roster search or display fields, but the county did not publish a formal demographic population table. The public roster uses age instead of full date of birth, and sampled rows did not show public addresses, phone numbers, full SSNs, projected release dates, or detailed housing assignments.

Laws for Union County Inmate Records

South Carolina law sets the background for public access, jail custody, bond, juvenile limits, and record clearing. The official roster remains the fastest access point for current Union County inmate population searches, but South Carolina FOIA is the fallback for booking or incident records that are public and not exempt. Law-enforcement records can still be withheld or redacted when release would harm an investigation, fair-trial rights, privacy, safety, sources, or protected techniques.

Search the Union County Inmate Population

The official jail lookup is the Union County inmate portal. It is linked from both the detention-center page and the sheriff's office page. The portal is free and public, with no login shown for roster searches. Its own disclaimer says information changes quickly, may contain errors, does not show guilt or innocence, and should not be used for legal action. For more inmate information, the portal directs users to call the detention center.

1. Open the Union County inmate portal from the county detention center or sheriff page.
2. Leave the In Custody On date at the current date for someone believed to be held today.
3. Search by name first, then narrow by race, sex, arrest date, or held-for agency if needed.
4. Read the row for mugshot, name, race, sex, age, arrest date, agency, and hold reasons.
5. If the person does not appear, check SCDC, BOP, ICE ODLS, VINELink, or call the jail.

The portal is strongest for current or recent custody. Its in-custody date filter is limited to dates within the last seven days. That is not a full archive. If the person was released outside that recent window, a records request through the sheriff's office may be the practical next step.

Union County Roster Search Fields

The Union County inmate population portal exposes several filters. A name search is usually the best start, because held-for agency and arrest-date filters can be too narrow when a person has multiple holds or unclear booking dates. The system sorts and pages results, and the public client can show up to 50 records in a page load.

What Union County Inmate Records Show

The public roster is row-based. It does not expose a polished click-through profile in the research sample, but each row can carry a rich hold-reasons field. That field is where warrants, statute codes, charge text, bond type, bond amount or denial, arrest date, and judge information may appear. The visible columns are simpler: mugshot, name, race, sex, age, arrest date, and held-for agency.

Union County Jail vs State Prison

Custody systems split after sentencing. The county roster covers the jail and work-camp custody route. SCDC covers sentenced state prisoners after transfer. BOP covers sentenced federal inmates from 1982 to present. ICE ODLS covers immigration detainees. VINELink is a notification and custody-status route, not a replacement for the jail roster or the state locator.

Note: a Union County inmate row can show another agency hold even when the person is physically in the county jail.

Union County Detention Facilities

Two facility pages are mapped from the research because the county separates the main detention center from the prison work facility. Both should be read as part of the same local detention campus, but they serve different custody functions.

• Union County Detention Center holds pretrial detainees, short county/city sentences, Family Court sentences, and people held for local or outside agencies.
• Union County Detention Center Prison Work Facility houses up to 20 state inmate workers and supports supervised county work details.

The detention center screenshot from the official county page shows the local jail information, inmate portal link, visitation rules, CIDNET phone/video route, and JailPackStore commissary route in one place.

The county page is also the source for the video-visitation and commissary instructions that apply to most local custody questions.

Union County Bond and Court Path

After arrest, the jail roster and the court file begin to diverge. The jail row shows booking facts and hold reasons. The court record shows the filed case, hearings, charge status, disposition, sentence, fines, and docket entries. The Union County Magistrate Court page says magistrates issue criminal arrest and search warrants and conduct bail bond hearings two times daily. More serious charges can move into General Sessions, where the Sixteenth Judicial Circuit Solicitor prosecutes criminal cases for Union County.

Bond phrases in the portal can include surety, cash/surety, denied, pending, or other status text. A surety bond usually involves a bondsman. A cash bond is money posted directly according to court or jail instructions. A no-bond or denied bond means money alone will not release the person unless the court changes the order. A local bond also may not clear an SCDC, probation, ICE, USMS, or outside-county hold.

Union County Visits and Money

The county publishes direct service routes for visits, phones, mail, and commissary. County sentenced and pretrial inmates use video visitation through CIDNET; visits are not scheduled at the detention center. State inmate visitation is listed for Saturday from 12 p.m. to 3 p.m., but visitors should confirm the person's custody category before scheduling. A victim or co-defendant in the charged crime is not allowed to visit or send mail to that inmate.

Union County Inmate Population FAQ

How large is the Union County inmate population? The county detention page reports an average population of 100 county/city detainees across the Pretrial and Work Camp Divisions. It also says the Prison Work Camp houses up to 20 state inmate workers. Those are official operating figures, not a daily live count.

Where does a Union County inmate search start? Start with the Union County inmate portal for current and recent county jail custody. Use the In Custody On date within the last seven days for recent custody. If the person has been sentenced to state prison, search SCDC instead.

Can the roster show mugshots? Yes. The Union County portal includes a mugshot column and sampled public rows returned booking-photo data. The roster should not be treated as a guaranteed historical mugshot archive after release.

What if the person does not appear? Call the detention center, check whether the person moved to SCDC, search BOP for federal custody, use ICE ODLS for immigration detention, and consider VINELink for custody notifications.
