Cobb County Adult Detention Center Overview
The Cobb County Adult Detention Center is operated by the Cobb County Sheriff's Office as the primary jail in the Cobb County Jail Complex. The sheriff describes the jail as a pretrial facility, which means many people held there have not been convicted in the case that brought them into custody. Others may be held after sentencing, before transfer, on a court order, or because another lawful hold keeps them from release. The Detention Facilities Division covers detainee processing, medical care, commissary, the inmate library, labor force, food service, security, work release, and incarceration records.
The complex is a large Marietta jail campus with about one million square feet under roof. Official facility history says Building A opened in 1987, Building B opened in 1997, and C Tower opened in 2010 with special sales tax funding. The sheriff's division page also names the Jail, Work Deployment Facility, and Annex as parts of the detention division. Those components matter for records because a person may be housed within the jail system while the public search route remains the same Cobb Sheriff inmate search.

Cobb County Jail Capacity
The confirmed local stat for the Cobb County Adult Detention Center is rated capacity, not a current daily head count. The sheriff publishes a combined capacity for A, B, and C Tower. Research did not locate an official average daily population, average length of stay, current daily count, or facility-level demographic table. That gap matters. Bookings over a quarter are not the same thing as the number of people in custody on a given day.
| Measure | Published Detail |
|---|---|
| Rated capacity | 3,077 beds for A, B, and C Tower combined. |
| Q1 2026 bookings | 4,512 bookings in the sheriff's HB 1105 quarterly report. |
| Current population | Not located in official public sources reviewed. |
| Separate Annex or Work Deployment count | Not separately published in the reviewed official sources. |
Lookup Cobb County Jail Inmates
Current county jail searches start with the Cobb Sheriff inmate search. The form accepts SOID, name, serial number, and a query selector for In Custody or Inquiry. The sheriff's custodial information page says the search can be used to obtain criminal charges and bond amounts. Use this route for people believed to be at the Cobb County Adult Detention Center, the Detention Annex, or a sheriff detention-division component.
- Open the official Cobb Sheriff inmate search, not a third-party roster.
- Search by SOID if known, or enter the name in the roster format using last name and first name.
- Choose In Custody when the person is believed to be held at the Adult Detention Center.
- Review the result for status, SOID, days in custody, and the booking buttons.
- Call the jail or Records and ID if the online result does not resolve custody or bond questions.
If the person has been sentenced and moved to state custody, the county roster may no longer be the right system. Use the Georgia Department of Corrections Find an Offender page for sentenced state prisoners. Federal custody belongs in the BOP locator, and civil immigration custody belongs in the ICE detainee locator. VINELink can help with custody and release notifications, but it is not a full jail booking file.
Cobb County Detention Center Contact
The jail complex and visitor-facing functions use nearby but distinct public locations. The main jail address is the Adult Detention Center address. The Visitor's Center is used for visitation, bonding, and inmate-account withdrawals. Confirm the correct counter before travel because records, bond, visiting, and jail administration are not all handled through the same public doorway.

Cobb County Jail Mail and Money
Mail, phone, and money rules for the Cobb County Adult Detention Center are documented on the sheriff inmate-services page. Personal mail and legal mail use different addresses. That split is important because personal mail is routed to a Phoenix, Maryland address, while legal mail and books use the Cobb Adult Detention Center post office box in Marietta. The inmate's full name and SOID number should be included.
| Service | Provider or Detail |
|---|---|
| Personal or other mail | Cobb County Sheriff's Office, Georgia; inmate name and SOID#; PO Box 247; Phoenix, MD 21131. |
| Legal mail and books only | Cobb County Adult Detention Center; inmate full name and SOID#; PO Box 100110; Marietta, GA 30061. |
| Phone provider | Global Tel Link, Inc.; inmates cannot receive incoming calls. |

Greeting cards and photos are the identified personal-mail contents, but Polaroids are not allowed. Books, magazines, and periodicals must come directly from a publisher or online distributor, and hardbound books are not accepted. U.S. Postal Money Orders are accepted by mail, and the sheriff recommends not mailing cash. Withdrawals are limited to once monthly with inmate consent, with Wednesday pickup at the Visitor's Center.
Cobb County Jail Booking
Booking at the Adult Detention Center is tied to sheriff custody, identification, records, medical screening, classification, and court movement. The Detention Facilities Division handles processing, medical care, and custody. The Records and Identification Unit maintains arrest and incarceration records, fingerprints, photographs, and court documents. The public admissions report gives another route for users who know a booking date range or charge class rather than a full name.
- SOID
- The Sheriff's Office identification number used in the Cobb jail search.
- Classification
- The jail assessment used to place a person in the proper security and housing setting.
- Detainer
- A hold or request from another agency that may affect release even when bond is posted.
- Bond
- Security or release conditions meant to assure future court appearance.
About Cobb County Adult Detention Center
The Adult Detention Center is the central facility for Cobb County jail custody and the most documented facility in the local detention map. It is also the records hub for many searches that begin with a municipal arrest, a court warrant, or a transfer into sheriff custody. The same jail complex connects to the Detention Annex and Work Deployment Center, but those components do not have separate public roster systems in the official sources reviewed.
County jail custody is not the same as a court case result. A booking charge may change once prosecutors review the case, and a release from jail does not erase the court record. For formal charges and case outcomes, use the relevant Cobb court records after the jail record identifies the person, SOID, charge, or booking context. For a broader walkthrough of the county search route, the Cobb County jail inmate records page explains roster fields and fallback channels.
Note: Confirm custody, visit status, and visitor limits with the jail before travel because schedules and housing can change.
