Calvert County Inmate Population Overview
The Calvert County inmate population is centered on the Calvert County Detention Center, the local jail run by the Calvert County Sheriff's Office Corrections Bureau. The county describes the detention center as the place used to hold pretrial suspected offenders for court appearance and short-term sentenced offenders until lawful release. That local jail role is important. A person arrested in Calvert County may be counted in the county jail population before any conviction, while a person sentenced to longer Maryland prison custody may later be counted by the Maryland Department of Public Safety and Correctional Services.
The county map also includes the Calvert County Work Release Building, a community-supervision program site tied to the detention center. It is not a separate state prison or city jail. It serves sentenced offenders who have court-approved work-release commitments and participants supervised through the Community Supervision Unit. No state prison, federal Bureau of Prisons facility, or ICE detention center was found inside Calvert County in the official facility research, so those searches use statewide or federal tools instead of a Calvert jail roster.
The official Calvert County Detention Center page is the main source for the jail's local custody role and contact information.
The county's own page confirms that Calvert County jail custody is handled through the Sheriff's Office Corrections Bureau rather than a state prison locator.
Calvert County Inmate Population Statistics
Calvert County inmate population figures come from two official streams that should not be blended without care. The Maryland FY 2025 Local Jails and Detention Centers capital analysis reports Calvert local jail average daily population for fiscal years 2018 through 2023 and lists the Q4 2023 operating capacity. The Sheriff's 2025 fourth quarterly report gives a later local snapshot that includes pretrial and home detention in its average daily inmate population count. Both are useful, but they answer different measurement questions.
| Measure | Figure | Source / Year |
|---|---|---|
| Average daily inmate population | 128, including pretrial and home detention | Calvert County Sheriff's Office Q4 2025 report |
| Local jail ADP | 89 | Maryland local jail table, FY 2023 |
| Operating capacity | 228 | Maryland local jail table, Q4 2023 |
| Bookings/intakes | 376 total, 293 male and 83 female | Calvert County Sheriff's Office Q4 2025 report |
| Releases | 373 total, 290 male and 80 female | Calvert County Sheriff's Office Q4 2025 report |
Calvert County Inmate Population Trends
The Maryland local-jail table shows a clear drop in Calvert County jail ADP between FY 2018 and FY 2023. Calvert reported 149 in FY 2018 and FY 2019, then fell to 116 in FY 2020, 111 in FY 2021, 104 in FY 2022, and 89 in FY 2023. The research notes that statewide locally detained ADP rose from FY 2022 to FY 2023, while Calvert moved the other way and fell by 15 people, or 14 percent, during that same span.
That trend does not mean every later daily count was below the FY 2023 figure. The Sheriff's Q4 2025 report gave a higher average daily inmate population of 128, and that figure includes pretrial and home detention. It is best read as a later local operations snapshot, not as a direct replacement for the statewide fiscal-year ADP series.
| Fiscal year or report period | Average daily population | Notes |
|---|---|---|
| FY 2018 | 149 | Maryland DPSCS source table in FY 2025 capital analysis. |
| FY 2019 | 149 | Same as prior year. |
| FY 2020 | 116 | Lower count during the early pandemic and court disruption period. |
| FY 2021 | 111 | Continued lower ADP. |
| FY 2022 | 104 | Still below 2018 and 2019. |
| FY 2023 | 89 | Down 15 from FY 2022. |
| Q4 2025 | 128 | Sheriff's quarterly count includes pretrial and home detention. |
Calvert County Jail Population Makeup
The official Calvert sources give more detail on program status and jail-health demand than on race, age, or charge-level demographics. The Q4 2025 report listed 376 bookings and 373 releases during the quarter, with male and female totals for each. It also reported 18 people on pretrial release, 7 on home detention, and 46 enrolled in reentry or behavioral-health services. Those figures show that the Calvert County inmate population is not limited to people locked in a housing unit. Some people are supervised through court-authorized community programs while still tied to the local corrections system.
- Pretrial release: 18 people were current in the Q4 2025 sheriff report.
- Home detention: 7 people were current in the Q4 2025 sheriff report.
- Reentry and behavioral health: 46 people were enrolled in the Q4 2025 report.
- Mental-health services: the report listed 376 intakes and 198 enrolled.
- Detox protocols: 26 intakes required detoxification in the quarterly report.
These local details matter during inmate lookup. A person may be in jail custody, on pretrial release, on home detention, in work release, transferred to state custody, or released. The search path changes with each status.
Calvert County Jail Capacity
The Calvert County jail building has a layered capacity history. The county history page says the Barstow jail opened in 1978 with a rated capacity of 92 inmates. A 1992 expansion raised the rated capacity to 172 and added maximum, medium, and minimum housing areas. The statewide FY 2025 local-jails analysis later listed Calvert's Q4 2023 total operating capacity as 228. Compared with the FY 2023 ADP of 89 in that statewide table, Calvert was not over capacity on that annual metric.
The research found no official recent consent decree, DOJ jail investigation, or Calvert jail overcrowding litigation in the official sources reviewed. It did find that a Calvert County Detention Center site and security improvements project was canceled and a fiscal 2020 authorization was no longer needed. Capacity claims should therefore stay tied to the official history page, the Maryland local-jail table, and any current sheriff operations report.
The Calvert detention center history page documents the former courthouse jail, the 1978 Barstow opening, and the 1992 expansion.
That history explains why older Calvert County inmate population references may use different rated-capacity numbers than the later state operating-capacity table.
Calvert County Inmate Population Laws
Maryland public-record law and correctional standards shape how Calvert County jail data can be requested and how local detention facilities are supervised. The county's PIA page says public records include photographs, copies, computerized records, maps, and other material created or received in public business. It also says there is no central PIA agency, so a requester must route the request to the office that keeps the record. For jail material, that usually means the Sheriff's Office or Detention Center through the county request process.
Key statutes:
Maryland General Provisions Section 4-103 states the public policy of access to information about government affairs and official acts.
Maryland General Provisions Section 4-201 requires a custodian to allow inspection unless another law permits denial.
Maryland Correctional Services Section 8-112 directs the state correctional standards commission to advise on and adopt standards for local facilities.
Maryland Correctional Services Section 8-114 covers compliance plans, audits, inspections, and enforcement for correctional standards.
Calvert County State Prison Search
No state prison was located inside Calvert County during the official facility sweep. Still, sentenced Calvert defendants can move into Maryland DPSCS custody after sentencing and classification. At that point, a county jail call or app search may no longer be the right tool. The Maryland DPSCS Incarcerated Individual Locator is the correct statewide lookup for covered people committed to the Commissioner of Correction and housed in Division of Correction facilities, Patuxent Institution, and some short-sentenced Division of Pretrial and Detention Services placements.
The DPSCS page warns that the locator does not list everyone in DPSCS custody and does not list people no longer in custody because of release or escape. For Calvert County inmate population work, that means state-prison search is a companion to the local jail channels, not a substitute for them.
Search Calvert County Inmate Population
The regular Calvert County website pages inspected for this build did not expose a browser-based jail roster form or public sample inmate profile. The sheriff's official mobile app listings, however, advertise corrections information that includes inmate search, visitation information, bail, and commissary payment options. That makes the app an important official channel for current local custody, while the jail phone line, VINE, PIA request process, and state or federal locators fill the gaps.
- Start with the official Calvert County Sheriff app if it can be installed. The app listings name corrections information and inmate search.
- If the app is unavailable or unclear, call the Calvert County Detention Center at 410-535-4300 or 301-855-9640.
- Use Maryland VINE for custody status and notification registration.
- For a booking sheet, older record, or booking photograph, submit a county PIA request with the person's name, date, and record sought.
- If the person was sentenced to state custody, search the Maryland DPSCS locator instead.
- If federal or immigration custody is possible, use BOP, U.S. Marshals context, or ICE's locator.
The Google Play listing for the Calvert County Sheriff's Office app is one official source for the app's corrections and inmate-search feature claim.
The app is useful because the county's standard website pages inspected for this project did not show the same public jail roster interface.
Calvert County Current Inmate Lookup
Current Calvert County inmate lookup starts with the systems that can answer present custody status. The sheriff app may show app-based inmate search results, but the app store listings do not reveal the exact search fields. The detention center phone line is staffed at all times and can confirm the right contact path. Maryland VINE can provide custody status and alerts, though VINE should not be the only source for safety planning or release decisions. If a person has moved out of local jail custody, Case Search, DPSCS, BOP, or ICE may be the better record system.
| Lookup channel | Best use | Limit |
|---|---|---|
| Sheriff app inmate search | Current local custody if the app can be used. | App-store pages do not show exact fields or sample records. |
| Detention center phone | Direct local custody and facility routing. | Record release may still require a formal PIA request. |
| Maryland VINE | Custody status and notification registration. | Not a full booking-record archive. |
| Maryland DPSCS locator | Sentenced people in covered state custody. | Not every county jail inmate or released person appears. |
| BOP and ICE locators | Federal or immigration custody. | Separate systems outside county jail control. |
Calvert County Past Inmate Records
Past Calvert County inmate records usually require a more specific request than a current custody check. Because the inspected county website did not publish a web archive of jail bookings or released inmates, older jail material should be requested through the Calvert Public Information Act process. The county's online form asks for the information requested and requester contact details. The form text says most records are produced within 10 working days, and the county may take up to 30 days if more time is needed.
A strong request names the person, booking date or date range, incident or court case number if known, and the specific item needed, such as booking sheet, charge information, release status, or booking photograph. Case Search may show the court case that followed the booking, but jail booking charges can differ from charges later filed by the State's Attorney.
The Calvert County online PIA form is the county's documented submission path for public-record requests.
PIA requests are the main fallback when a Calvert County inmate record is not available through the app, phone line, VINE, or a court case index.
Calvert County Inmate Record Fields
No public Calvert web roster profile was visible in the pages inspected, so online field claims must stay limited. The sheriff app advertises inmate search, but the store pages do not show a sample inmate profile. The fields below are the Calvert jail record details to ask about through official channels rather than a promise that each field appears on a public web page.
| Field | What It Means |
|---|---|
| Name | Use the full legal name when calling the jail or filing a PIA request. |
| Booking number | Ask whether a booking number was assigned if it is not on court paperwork. |
| Mugshot | A booking photograph may be requested, subject to PIA exemptions and expungement limits. |
| Charges | Booking charge data may differ from court charges later filed or amended. |
| Bond or release status | Status may involve bond, pretrial release, home detention, work release, detainers, or a hold. |
| Court date | Verify court events through Maryland Judiciary Case Search or the clerk. |
Calvert County Jail vs Prison
Many failed inmate searches happen because the search starts in the wrong system. Calvert County Detention Center handles local pretrial custody and short local sentences. DPSCS handles covered sentenced state custody. BOP handles federal prison records from 1982 to present. ICE handles immigration custody and CBP custody over 48 hours. A Calvert arrest can begin in the county jail and later move to a different system if court or federal action changes custody.
| System | Who It Covers | Where to Search |
|---|---|---|
| County jail | Pretrial detainees and short local sentences. | Sheriff app, detention center phone, VINE, PIA request. |
| Maryland state prison | People committed to covered DPSCS custody. | DPSCS Incarcerated Individual Locator. |
| Federal custody | Federal inmates and some pretrial federal prisoners. | BOP Inmate Locator and U.S. Marshals custody context. |
| Immigration custody | ICE custody or CBP custody over 48 hours. | ICE Online Detainee Locator. |
Calvert County Detention Facilities
Calvert County's local detention facilities are concentrated at the Stafford Road corrections site. The detention center is the main local jail. The work release building is a separate county-identified program building in the same parking lot, used for court-approved work release and community-supervision activity. The facility list should not be expanded with state prisons or federal detention centers unless an official source places one inside Calvert County.
- Calvert County Detention Center holds pretrial detainees, short-sentence offenders, and male and female local offenders under the Sheriff's Office Corrections Bureau.
- Calvert County Work Release Building supports sentenced offenders approved for work release and related Community Supervision Unit activity.
Calvert County Inmate Population FAQ
How large is the Calvert County inmate population? The sheriff's Q4 2025 report listed an average daily inmate population of 128 including pretrial and home detention. The statewide FY 2023 local-jail ADP line listed 89 for Calvert, so compare figures by source and time period.
Is there a Calvert County web jail roster? The county website pages inspected did not show a browser-based public jail roster. The official sheriff app listings advertise inmate search, and the jail phone, VINE, and PIA process are key fallbacks.
Where are sentenced Calvert inmates listed? Sentenced people moved into covered Maryland state custody should be checked through the DPSCS locator, not only through Calvert County jail channels.
Can past booking records be requested? Yes, but older jail records generally require a specific Calvert County PIA request naming the person, date, and record sought.
