The Cobb County Inmate Population
The Cobb County inmate population is centered on the Cobb County Adult Detention Center, the sheriff-run jail complex in Marietta. The sheriff describes the jail as a pretrial facility and identifies the Detention Facilities Division as the unit that handles detainee processing, medical care, commissary, food service, facility security, work release, and incarceration records. The local facility map also includes the Work Deployment Center, the Detention Annex, and the City of Smyrna Jail, so custody searches can split by agency and custody type.
Population means more than a head count on one day. Cobb County publishes the strongest local jail data through facility capacity and quarterly booking reports. Those reports show admissions, immigration-status inquiries, and ICE detainers under Georgia's jail-reporting law. They do not publish a full average daily population, length-of-stay table, or demographic breakdown in the official sources reviewed. That limit matters because bookings are admissions over time, while population is the number held at a point or on an average day.
Cobb County Inmate Population Statistics
Cobb County's firmest jail-size figure is the Adult Detention Center capacity. The sheriff says A, B, and C Tower together have 3,077 beds. The same official division page says the complex covers about one million square feet under roof and has three major building phases. The public quarterly jail reports add booking volume, but they are not a live roster and should not be read as a current inmate count.
The table below separates confirmed numbers from research gaps. It uses official Cobb Sheriff pages and reports where a number was located. It also labels the derived 2025 booking total as a calculation from quarterly reports, not as a separate annual statistic published by the sheriff.
| Measure | Figure | Source / Date |
|---|---|---|
| Rated jail capacity | 3,077 beds | Cobb Sheriff Adult Detention Center page, reviewed 2026 |
| Q1 2026 bookings | 4,512 | Cobb Sheriff Q1 2026 HB 1105 report |
| 2025 bookings | 18,142 | Calculated from official Q1-Q4 2025 quarterly reports |
| Average daily population | Not located | Request from Cobb Sheriff through open records |
| Average length of stay | Not located | Request from Cobb Sheriff through open records |
Cobb County Jail Booking Trends
Cobb's quarterly reports give a useful view of jail activity even without a published average daily population. Bookings stayed within a narrow band across the reports reviewed, from 4,423 in Q2 2025 to 5,102 in Q4 2024. ICE detainers increased across the same series, from 71 in Q4 2024 to 129 in Q1 2026. These figures are process counts. They should not be converted into a claim about the number of people in the jail at one time.
| Period | Bookings | Immigration / LESC Inquiries | ICE Detainers |
|---|---|---|---|
| Q4 2024 | 5,102 | 664 | 71 |
| Q1 2025 | 4,458 | 355 | 91 |
| Q2 2025 | 4,423 | 286 | 99 |
| Q3 2025 | 4,810 | 968 | 115 |
| Q4 2025 | 4,451 | 516 | 104 |
| Q1 2026 | 4,512 | 516 | 129 |
Note: The Q1 2025 report has a heading-date anomaly in the research notes, but its body date range is January 1, 2025 through March 31, 2025.
Who Is Counted in Cobb County Custody
The Cobb County inmate population spans several categories. The Adult Detention Center holds pretrial detainees, people with criminal charges and bond records, and people held for court, transfer, or other lawful holds. The Work Deployment Center holds non-violent under-sentence detainees assigned to work crews or approved work release. The Detention Annex is a named component of the sheriff's detention division, but separate population figures were not published in the official sources reviewed.
Municipal custody is narrower. Smyrna has a police jail function, and Acworth says its former detention center no longer houses inmates. Acworth detainees may go to Smyrna or the Cobb County Adult Detention Center depending on circumstances. Sentenced state prisoners move into the Georgia Department of Corrections Find an Offender system. Federal sentenced inmates use the BOP locator, and ICE detainees use the ICE locator.
- Pretrial custody
- Jail custody before a case is resolved, often while bond, hearings, or charges are pending.
- Booking
- The jail intake record created after arrest, including identity checks and custody processing.
- Work release
- A custody program for approved sentenced detainees who leave for work and return to custody.
- Detainer
- A hold or request from another agency, such as ICE or another jurisdiction.
Cobb County Jail Capacity and Layout
The Adult Detention Center has unusually detailed building history. Building A opened in 1987, Building B opened in 1997, and C Tower opened in 2010 with special sales tax funding. The sheriff reports about one million square feet under roof and 3,077 combined beds for A, B, and C Tower. The capacity figure is local and official, but it does not prove the jail is crowded or under capacity today because a current average daily count was not located.
The sheriff lists the Jail, Work Deployment Facility, and Annex as parts of the Detention Facilities Division. That structure affects record searches. A person may be within the sheriff's detention system even if the public-facing search result does not name a tower, unit, or annex placement. For urgent housing, transport, or visitation questions, the jail information line and Records and Identification Unit are better fallback channels than guessing from a roster field.
Laws Governing Cobb County Jail Population Reports
Georgia law controls both access to records and the way jail activity is reported. The Georgia Open Records Act generally treats public records as open unless an exemption applies. A separate jail-reporting law requires county jails and municipal detention facilities to prepare and post at least quarterly reports. Booking-photo release has its own rule, which is why Cobb's roster search notice says booking photographs are no longer posted on the sheriff website.
Key Statutes:
O.C.G.A. 50-18-70 states Georgia's open-records policy and definitions.
O.C.G.A. 50-18-71 covers timing, access, fees, denials, and electronic records.
O.C.G.A. 42-4-16 requires quarterly county-jail and municipal-detention reporting.
O.C.G.A. 45-16-25 is relevant when suspicious or unusual deaths require coroner or medical examiner investigation.
Cobb County and State Prison Counts
State prison numbers are separate from the Cobb County jail population. The Georgia Department of Corrections reported 53,500 active inmates in its May 2026 profile, produced June 1, 2026. That report also listed 1,512 active GDC inmates with Cobb as self-reported home county and 2,316 active GDC inmates with Cobb as county of conviction for the primary offense. Those people are in state custody, not necessarily held in Cobb County.
No GDC state prison, private prison, transitional center, probation detention center, BOP federal prison, or over-72-hour ICE detention facility was identified as physically located in Cobb County in the official sources reviewed. The state, federal, and ICE systems still matter because a person arrested in Cobb may later transfer out of the county jail. The right search source changes after that transfer.
How to Search the Cobb County Inmate Population
The official Cobb Sheriff inmate search is the first online channel for current jail custody. It is hosted at inmate-search.cobbsheriff.org and accepts SOID, name, serial number, and a query selector. The sheriff's custodial information page says the search can be used to obtain criminal charges and bond amounts. The same search page links to the admissions report and the Georgia Criminal Alien Tracking and Reporting Act report.
Use the roster as a custody tool, not as a court-record search. Booking charges can change after a prosecutor files formal charges. For case status after arrest, the Cobb State Court and Superior Court Clerk portals are the better court-record channels.
- Open the official Cobb Sheriff inmate search and begin with the broadest known identifier, usually the name field.
- Enter the name in the form's order, last name followed by a space and first name, when both are known.
- Use SOID or serial number when available, because the search page says SOID improves query performance.
- Select In Custody when the person is believed to be at the Cobb County Adult Detention Center.
- If no result appears, try Inquiry, the admissions report, the jail phone line, open records, GDC, BOP, ICE, or VINELink based on the custody stage.
Cobb County Roster Search Fields
The Cobb search form is more detailed than a simple last-name roster. It supports identifiers that help distinguish people with common names and repeat bookings. The Inquiry option is broader and may take longer, so In Custody is the practical first choice when the person is believed to be held at the Adult Detention Center.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| SOID | Text | Optional | Sheriff's Office identification number; the search page says it improves performance. |
| NAME | Text | Optional | Field title says last name, space, first name. |
| Serial | Text | Optional | Inmate serial number used to narrow a search. |
| qry | Dropdown | Yes | Options are In Custody and Inquiry; In Custody is the default. |
The Cobb Sheriff admissions report is a second route when a booking date range or charge class is known. Its charge filter includes categories such as DRUG, DUI, FIREARMS, MUNICIPAL, ROBBERY, SEXUAL, TRAFFIC, and WEAPON, including some duplicate case variants.
What Cobb County Inmate Records Show
Cobb's public result list showed a timestamp and matching records for people presently incarcerated during research. The visible fields help distinguish one person from another, but they do not provide every detail a family member may want. The sheriff says charges and bond amounts are available through inmate search, while the inspected result list itself showed a summary-level row and buttons for booking history.
| Field | What It Shows |
|---|---|
| Image | The column exists, but booking photos are not posted under the sheriff's O.C.G.A. 35-1-19 notice. |
| Name | Full uppercase name. |
| DOB | Birth year only in the result list, not full date of birth. |
| Race / Sex | One-letter race code and M or F sex code. |
| Location | Status-like text such as IN JAIL or RELEASED. |
| SOID | Sheriff's Office identification number. |
| Days in Custody | Integer day count, not a sentence length or release estimate. |
| Last Known Booking | Button to the booking-detail endpoint. |
| Previous Bookings | Button appears when prior booking history exists. |
County Jail vs State Prison
Many search failures happen because the person is in a different custody system. The county roster is for Cobb jail custody and inquiry records. GDC is for sentenced state prisoners. The BOP locator covers federal inmates from 1982 to present, while ICE's online locator covers civil immigration detention. VINELink is useful for custody and release notifications, but it is not a full booking-record database.
| Custody Stage | Correct Channel | What It Covers |
|---|---|---|
| County pretrial or short sentence | Cobb Sheriff inmate search | Jail custody, inquiry records, charges, bond amounts |
| Sentenced Georgia prisoner | GDC Find an Offender | State prison custody after transfer |
| Federal sentenced inmate | BOP inmate locator | Federal inmates from 1982 to present |
| ICE detainee | ICE Online Detainee Locator | Immigration detention by A-number or biographic search |
| Custody notification | VINELink | Notifications for participating jail custody and release events |
Cobb County Detention Facilities
The facility list should be read as a custody map, not as a promise that every facility has its own public roster. The sheriff-run facilities use the Cobb Sheriff inmate search and detention contacts. Smyrna's municipal jail function uses Smyrna Police contact information unless a detainee has been transferred to the Cobb Adult Detention Center.
- Cobb County Adult Detention Center - the main county pretrial jail and central Cobb County inmate population facility.
- Cobb County Work Deployment Center - minimum-security work deployment and work release for eligible non-violent sentenced detainees.
- Cobb County Detention Annex - a named sheriff detention-division component within the jail complex.
- City of Smyrna Jail - a municipal police jail function, including possible Acworth detainee routing.
Cobb County Booking Photos and Court Records
Cobb's jail roster is not a mugshot gallery. The search page states that the Cobb County Sheriff's Office will discontinue posting booking photographs to the sheriff website under O.C.G.A. 35-1-19. The Records and Identification Unit maintains photographs, fingerprints, arrest and incarceration records, and court documents for detainees, but release of a booking photo can require a public-records process and statutory certification.
After arrest, court records follow a different path. State Court records and Superior Court Clerk records are used to track filed charges, case status, and later dispositions. The jail roster may show booking charges and bond amounts, but it does not prove the prosecutor filed the same charges in court. Bond, first appearance, detainers, and transfer status can also affect whether a person stays in custody after booking.
For more focused custody details, the Cobb County jail inmate records page follows the roster fields and fallback channels, while the Cobb County jail mugshots page explains booking-photo limits.
Cobb County App and Records Requests
The official Cobb County Sheriff's Office app appears in the Apple App Store and Google Play. Store listings describe tips, public feedback, public safety news, and emergency alerts. They do not confirm an app-only jail roster, warrant search, or most-wanted lookup, so inmate lookup should still route through the official web roster, jail phone line, Records and Identification Unit, and open-records portal.
When the online roster does not answer a question, use the Cobb Sheriff open-records page and GOVQA portal. The sheriff lists Open Records Requests at (770) 499-4728 and Records and ID at (770) 499-4231. Records can be limited by active investigation, prosecution, juvenile, sealed-record, court-order, and booking-photo rules.
