The Frederick County Inmate Population
The Frederick County inmate population begins at the Frederick County Adult Detention Center, the sheriff-operated local jail in Frederick. That facility handles traditional incarceration, Central Booking, people awaiting trial, local sentenced custody, and several alternatives to incarceration. The official sheriff page names Pre-Trial Services, Home Detention, Alternative Sentencing/Community Service, and Work Release as part of the local corrections bureau. Those programs matter because not every person under correctional control is sitting in a jail housing unit.
The county jail count is not the same as the Maryland state prison count. A person arrested in Frederick County may start in Central Booking, remain at the Adult Detention Center while the case is pending, move into work release or home detention, or transfer to the Maryland DPSCS incarcerated-individual locator after a state sentence. Federal sentenced inmates are searched through the Federal Bureau of Prisons inmate locator, and immigration detainees are searched through ICE ODLS. No state prison, BOP prison, or active ICE detention facility was located inside Frederick County in the official facility sources reviewed.
Frederick County Inmate Population Statistics
Current average daily population and rated jail capacity were not located in a current official public Frederick County dashboard or jail roster. The strongest local figures in the research are staffing, volunteer, medical-unit, and state budget details. Those numbers still help explain the scale of the Frederick County inmate population because they show how the Adult Detention Center is staffed and how recent jail construction responded to medical and female-housing pressure.
| Measure | Figure | Source / Year |
|---|---|---|
| Corrections Bureau staffing | Nearly 200 employees, including 140 correctional officers | FCSO Adult Detention Center page, inspected June 2026 |
| Volunteers serving incarcerated and community-based populations | More than 50 | FCSO Adult Detention Center page |
| Medical unit addition | 14,046 square feet and 26 medical beds | FCSO 2024 release and Maryland FY2024 budget material |
| Current jail ADP | Not located in current official public sources | County and sheriff sources reviewed |
| Full rated capacity | Not located in current official public sources | County and sheriff sources reviewed |
Frederick County Jail Trends
State budget material gives context rather than a live Frederick County inmate population dashboard. The research notes that Maryland local jail average daily population fell before fiscal 2018, rose briefly, then declined during the pandemic period. A later state budget analysis says the statewide local jail population remains below pre-pandemic levels but has increased from its low point. Frederick County-specific trend data was thinner, so the build should not turn state trends into a current county count.
| Year or Period | Reported Trend | Source / Note |
|---|---|---|
| FY2018-FY2022 | Maryland local jail ADP moved from 21,205 to 16,933 in the cited snippet | Justice Reinvestment Oversight Board snippet in research |
| FY2022-FY2024 | Frederick ADC medical addition was funded and completed | Maryland local jails capital budget analyses |
| FY2025 context | State local jail population remained below pre-pandemic levels but above the low point | Maryland FY2025 budget analysis |
The narrow local capacity point is medical and female housing, not a proven current systemwide overcrowding figure. Maryland FY2022 capital budget material described an old nine-inmate medical space, female detainee population pressure, and a facility operating closer to 90 percent capacity in that project context. The later medical unit was designed to expand care space and reduce outside hospital transports.
Laws for Frederick County Inmate Records
Maryland law starts from public access, then limits release when another law, court rule, privacy interest, juvenile rule, security concern, or investigative need applies. That is why Frederick County booking, custody, court, and mugshot information cannot be treated as one open database. The sheriff controls local jail and booking records, the courts control case records, and DPSCS controls state-prison locator data.
Key Statutes:
Maryland General Provisions Section 4-103 sets the public-access policy for government records, subject to statutory limits.
Maryland Correctional Services Section 8-103 requires minimum standards for state and local correctional facilities.
Maryland Chapter 956 of 2024 created a Deaths in Custody Oversight Board for statewide review duties.
Maryland Commercial Law Section 14-1324 addresses removal requests for fee-charging websites that publish arrest or detention images.
How to Search Frederick County Inmates
No official public Frederick County jail roster was located in the sources reviewed. That changes the lookup order. A current search for the Frederick County inmate population should begin with the Adult Detention Center, Central Booking, Offender Records, Maryland VINE, and the sheriff records-request process. The FCSO weekly arrest log can help identify a recent booking, but it is not a live custody roster and does not show housing, bond, booking number, or mugshot fields.
- Call the Adult Detention Center main line or Central Booking when the arrest is recent and custody status is urgent.
- Use Maryland VINE for custody status and notification registration.
- Search Maryland Judiciary Case Search after charges are entered by the court.
- File a sheriff records request through FCSO GovQuest for booking, incident, photo, or public-record material.
- Use DPSCS, BOP, or ICE locators when the person has moved into state, federal, or immigration custody.
Search terms should use the person's legal name, date of birth if known, arrest date, arresting agency, and any court case number. The weekly arrest log shows that people arrested by Frederick City Police, Maryland State Police, Thurmont Police, Brunswick Police, the Department of Natural Resources, and other agencies may still pass through county Central Booking.
Frederick County Inmate Lookup Fields
Because no county roster search form was located, there is no official Frederick County roster field table to publish. The state locator and court search fields are still useful when the local jail fallback points away from the county. The DPSCS locator is the best state-prison search after sentencing, while Case Search is the court-record search after charges are filed.
| System | Field | Use | Limit |
|---|---|---|---|
| Maryland DPSCS locator | First Name | State custody search | Does not list every DPSCS custody case |
| Maryland DPSCS locator | Last Name | Primary name search | Use legal spelling where possible |
| Maryland Case Search | Name or case number | Formal charges and hearing dates | CAPTCHA, exact-name default, result limits |
| FCSO GovQuest | Request details | Booking records, photos, incident reports | Interactive request portal |
What Frederick County Inmate Records Show
Official Frederick County sources reviewed did not publish a public inmate-profile screen. Known public material is narrower. The weekly arrest log names arrestees, ages, and abbreviated charge descriptions for a week, but it is not a complete roster. Court records add formal case details after filing. Records requests may be needed for booking or photograph records that are releasable under Maryland law.
| Record Item | Where It Is Most Likely Found |
|---|---|
| Current custody | ADC main line, Central Booking, Offender Records, or Maryland VINE |
| Recent arrest log entry | FCSO weekly arrest log posts |
| Formal charges | Maryland Judiciary Case Search and courthouse files |
| Booking photo if releasable | FCSO GovQuest records request |
| State prison housing | Maryland DPSCS locator |
Note: A booking entry and a court case can use different charge wording because prosecutors may amend, reduce, add, or decline charges.
Frederick County Jail vs State Prison
Frederick County jail custody is local. Maryland state prison custody is statewide. Federal and immigration custody are separate systems. Confusing those systems is the main reason inmate searches fail, especially after a person is sentenced or transferred.
| County Jail | State Prison | Federal or ICE | |
|---|---|---|---|
| Who is held | Recent arrestees, pretrial detainees, local sentences | People committed to the Commissioner of Correction | Federal sentenced inmates or immigration detainees |
| Run by | Frederick County Sheriff's Office | Maryland DPSCS | BOP or ICE |
| Where to search | ADC phone lines, VINE, records requests | DPSCS locator | BOP locator or ICE ODLS |
Frederick County Detention Facilities
The local facility map has two Frederick County corrections sites. The Adult Detention Center is the main jail and Central Booking location. The Work Release Center is a community-corrections facility tied to the same sheriff corrections bureau, not a state prison.
- Frederick County Adult Detention Center - local adult jail for central booking, pretrial custody, local sentenced custody, and correctional programs.
- Frederick County Work Release Center - local work-release and community-corrections facility with video-only visitation.
Frederick County Custody Sources
The official Adult Detention Center page is the core county source for the jail operator, correctional divisions, alternatives to incarceration, staffing, and the facility contact block.
That source supports the local facility map and explains why jail lookup questions should start with the sheriff corrections bureau, not a state prison locator.
For state custody, the Maryland DPSCS locator is the relevant search page after a Frederick County sentence results in state correctional commitment.
The state locator should not be used as a substitute for Central Booking when the arrest just happened, but it becomes important after transfer to Maryland state custody.
Frederick County Inmate Population FAQ
Is there a public Frederick County jail roster?
No official public current jail roster was located in the Frederick County sheriff sources reviewed. Use the Adult Detention Center, Central Booking, Offender Records, Maryland VINE, and the FCSO records request portal for custody and booking information.
How big is the Frederick County inmate population?
A current official county jail ADP was not located. The research supports local facility staffing, medical-unit beds, and state local-jail trend context, but it does not support a precise current inmate count.
Where do sentenced Frederick County inmates go?
After state sentencing, a person may move from the county jail into Maryland DPSCS custody. The DPSCS locator then becomes the better search tool than county jail phone lines.
Does Frederick County publish jail mugshots?
The sources reviewed did not show a county mugshot roster. Weekly arrest logs list booking-style information without photos. Releasable photographs should be requested through FCSO records channels.
