Annex Facility Overview
The York County Detention Center Annex is the smaller building in York County's two-building detention center. It is operated by the York County Sheriff's Office as a county-jail annex. The key local fact is its history: the Annex was formerly known as York County Prison, but the Sheriff's Office obtained custody of the county prison in July 2021 and merged all operations under the York County Detention Center.
That merger controls how the Annex should be searched. The Annex does not have a separate public roster, separate mail vendor, separate commissary process, or SCDC-style prison locator. The same York County Detention Center roster, phone system, visitation approval process, mail rules, commissary options, property release process, and FOIA route apply unless staff give an inmate-specific instruction.
The official detention overview documents the Annex as part of the York County Detention Center.
The official page is important because it prevents a common mistake: treating the Annex as a separate SCDC prison instead of a county-operated annex.
Annex Capacity and History
The Sheriff's Office lists the York County Detention Center Annex as a 256-bed direct-supervision facility. Its former York County Prison identity can lead to confusion, but current official sources place it under the York County Detention Center. The Main Building adds 621 beds, so the two-building center has 877 official beds. A public roster count inspected on June 29, 2026 showed 439 current bookings across the detention center, not a separate Annex population count.
The Annex should be treated as a facility-specific part of the same county-jail system. Building placement or housing assignment may depend on classification, bed management, court status, medical needs, behavior, or other detention decisions that are not published in the public roster. The York County inmate population overview explains the combined detention center count and capacity context.
Who the Annex Holds
The research file does not identify an Annex-only population category. It says the Annex is part of the local detention center population and should use the same custody categories unless the Sheriff's Office later publishes a separate Annex-specific housing assignment. The overall York County Detention Center holds people arrested by York County agencies until bond, court release, or transfer after sentencing. It also holds people sentenced to less than 90 days and Family Court sentences.
Federal and immigration custody can also intersect with the local jail. York County's detention page says the detention center houses U.S. Marshals Service and Immigration and Customs Enforcement detainees under agreements. Where appropriate, an Annex roster result may still require federal court, USMS, BOP, or ICE follow-up. Federal sentenced prisoners are searched through the BOP locator, and South Carolina sentenced prisoners after transfer are searched through SCDC.
| Custody type | Annex relevance | Lookup path |
|---|---|---|
| Local pretrial | County detainee awaiting bond, release, court, or disposition. | York County current roster. |
| Short local sentence | Local sentences under 90 days or Family Court sentences. | York County current roster and jail information. |
| U.S. Marshals detainee | May be housed locally under agreement. | York County roster plus federal court or USMS context. |
| ICE detainee | May be held locally under agreement. | York County roster and ICE ODLS. |
| State-prison sentence | After SCDC transfer, no longer a county roster case. | SCDC inmate search. |
Search Annex Inmate Records
Use the same York County current inmate roster for Annex inmate lookup. The roster table shows current bookings only. Public fields include name, booking date, city, state and ZIP, race and sex, height and weight, age, booking photo, facility, booking number, release status, total bond, charge sequence, charge description, and arresting agency. The inspected roster did not show exact housing unit, date of birth, court date, attorney, warrant number, or bond type. The York County jail inmate records page covers the same roster fields in more detail.
- Open the official York County current inmate roster.
- Search by last name or browse the sorted roster pages.
- Confirm the person is listed under York County Detention Center.
- Use booking number, charge wording, and arresting agency for court or FOIA follow-up.
- Check SCDC, BOP, ICE, or VINELink if the person is not in current county custody.
A separate York County Sheriff's Office South Carolina app-only inmate roster was not located during research. Use the web roster, phone menu, court index, and FOIA fallbacks instead of downloading an app for a different York County.
Annex Address and Contact
The Annex uses the York County Detention Center complex address and detention phone contacts. Because the Annex is integrated with the full detention center, callers should be ready with the inmate's name, booking number if known, and the reason for calling, such as visitation, mail, bond, property, or records.

Annex Visitation Rules
Annex visitation follows the York County Detention Center process. The inmate must initiate the visitation request and list up to six friends or family members. Visitors must be at least 17 and must bring valid government-issued ID. Once approved, the inmate receives an assigned one-hour time slot on a specific day. Only two approved visitors may visit at one time during that assigned hour.
The official visitation and communication page applies to the detention center system used by the Annex.
The page confirms that visitor approval, Smart Communications video visits, phone calls, and mail are handled as centralized detention-center services.
| Visitation item | Annex rule | Practical note |
|---|---|---|
| Who starts it | The inmate submits the request form. | Family cannot create the list alone. |
| Approved list | Up to six friends or family members. | Changes are inmate initiated once every 30 days. |
| Age | Visitors must be at least 17. | Bring valid government ID. |
| Visit length | One assigned hour on one assigned day. | Only two approved visitors at one time. |
| Video visit | Smart Communications / SmartJailMail. | Create an account and request connection. |
Annex Mail and Commissary
The Annex uses the same mail, phone, messaging, commissary, and property systems as the Main Building. Regular mail is sent to the Smart Communications scan-mail address in Seminole, Florida, with inmate name and ID number. Legal mail and money orders go directly to the detention center address in York. Phone calls are outgoing collect or debit calls after booking, and electronic messaging uses SmartJailMail.
| Service | Annex process | Important detail |
|---|---|---|
| Regular postal mail | YCDC, Inmate Name and ID Number, P.O. Box 9148, Seminole, FL 33775-9148. | Scanned into kiosks. |
| Legal mail | Inmate Name and ID Number, YCDC, 1675-3A York Highway, York, SC 29745. | Sent to facility address. |
| Money orders | U.S. Postal or Western Union money order mailed to the facility. | Cash not accepted. |
| Lobby kiosk | Deposit option at the detention center lobby. | Use current lobby rules. |
| Online commissary | jailpackstore.com from the Sheriff's commissary page. | Inmates can order once a week. |
| Property pickup | Authorized by inmate Property Release Form. | Tuesday or Thursday time windows with valid ID. |
Annex Booking and Bond
People are booked into the York County Detention Center system, not into a separate Annex public database. Intake can include identification, booking number, charge information, arresting agency, property inventory, booking photo, phone PIN issuance, and classification. The public roster shows current booking data once entered, but it does not publish every internal housing or classification detail.
Bond is set through the same York County bond process. Hearing time is tied to booking window and may occur outside normal business hours because Bond Court is inside the detention center and has a judge on duty 24/7/365. For immediate bond questions, use 803-628-3083, option 5. For court-date or case questions, York County directs users to the 16th Circuit Solicitor at 803-628-3020, and Public Defender questions to 803-628-3031.
Use the roster or inmate information line for current booking and custody, the Magistrate Judge phone path for release conditions, the Public Index and Clerk of Court for criminal case records, and federal or ICE sources when a hold may block local release.
Annex Programs and FOIA
Program and conditions reporting is published for the detention center as a whole, not as an Annex-only dashboard. The Sheriff's mission statement says the center aims to provide safe custody, trained staff, appropriate programs, nutritional and physical well-being, and compliance with state standards. Annual reports list detention-wide program hours, inmate attendance, medical visits, mental-health visits, prescriptions, and outside medical-care transports.
Records not visible online should be requested through the York County Sheriff's FOIA process. Requests go to the Sheriff's Office General Counsel at 1675-2A York Highway, York, SC 29745, or by the FOIA email listed on the official page.
South Carolina FOIA allows access to many public records but also allows exemptions and redactions for active investigations, privacy, safety, confidential sources, and other protected material. Annex-specific records may still be processed through the same Sheriff's Office records route because the Annex is part of the detention center.
Note: Confirm whether an inmate is in current county custody before using SCDC, BOP, or ICE as the main lookup source.
