Calvert County Detention Center Inmate Lookup

Calvert County Detention Center Overview

Calvert County's official Detention Center page describes the facility as the county jail responsible for holding pretrial suspected offenders so they appear in court and holding short-term sentenced offenders until lawful release. It is operated by the Calvert County Sheriff's Office Corrections Bureau, with Major Timothy Fridman identified in the research as administrator. The jail serves male and female offenders and is staffed around the clock.

The facility sits at 325 Stafford Road in Barstow. The jail mailing address is P.O. Box 9, Barstow, MD 20610. The same Stafford Road correctional campus also includes the separately listed Calvert County Work Release Building, but that building is not a separate public jail roster or state prison. For current county custody, the detention center remains the main jail point of contact.

The official detention page is the best visual match for this facility's public contact information and correctional overview.

Use the contact block from the county page for facility-level questions, then use the lookup steps below when the question is about a specific inmate record or custody status.

Calvert County Detention Center Capacity and Population

The modern jail has several capacity figures because the building changed over time and different official sources measure different things. The county history page says the Barstow jail opened in 1978 with a rated capacity of 92. A 1992 expansion raised the rated capacity to 172 and added maximum, medium, and minimum housing areas. The statewide Maryland FY 2025 Local Jails and Detention Centers capital analysis later listed Calvert's total operating capacity at 228 for Q4 2023.

The population trend is also sourced. The Maryland local-jail table listed Calvert average daily population at 149 in FY 2018, 149 in FY 2019, 116 in FY 2020, 111 in FY 2021, 104 in FY 2022, and 89 in FY 2023. The Sheriff's 2025 Fourth Quarterly Report separately reported an average daily inmate population of 128, including pretrial and home detention. Those two figures should not be treated as identical methods, but together they show that the jail population has been below the 228 operating-capacity line cited for Q4 2023.

How to Look Up an Inmate at Calvert County Detention Center

Calvert County's regular web pages did not expose a public browser-based jail roster during the research sweep. The official sheriff mobile app listings, however, advertise corrections information including inmate search, visitation information, bail, and commissary payment options. That makes the app the first official digital channel for many county-jail searches, with the detention center phone line, Maryland VINE, and the county Public Information Act process as the main fallbacks.

1. Start with the official Calvert County Sheriff mobile app if you can install it. The Google Play and Apple listings identify the app by Calvert County Sheriff naming and OCV, LLC as publisher or developer.
2. If the app is unavailable, inconclusive, or does not show the person, call the detention center at 410-535-4300 or 301-855-9640. The jail operates 24 hours a day, seven days a week.
3. Use Maryland VINE for custody status and notification registration. The Maryland VINE service number is 1-866-634-8463, and TTY is 1-866-847-1298.
4. For a booking sheet, older jail record, or booking photograph request, submit a Calvert County Public Information Act request and route it to the Sheriff's Office or closest available county organization.
5. If the person has been sentenced to state custody, search the Maryland DPSCS Incarcerated Individual Locator. It is not a full county-jail roster and may not list released people.
6. If federal or immigration custody is possible, use the BOP inmate locator, U.S. Marshals channels, or the ICE Online Detainee Locator rather than the county jail.

Calvert County Detention Center Address and Contact

Use the detention center contact information for custody confirmation, visitation appointment questions, mail and money questions, property release arrangements, and facility-specific records routing. The Sheriff's Office headquarters is separate from the jail, so time-sensitive custody questions should start with the correctional facility.

Visiting Someone at Calvert County Detention Center

Calvert's official visitation rules make visits appointment-only. The visitor must be on the inmate's visitation list, and children must be listed as well. To schedule, call 410-535-4300 extension 8944 on Monday or Tuesday between 8 a.m. and 2 p.m. Visits are 30 minutes, one visit per week per inmate, and take place on Saturday or Sunday between 8 a.m. and 8 p.m.

Visitors need photo identification showing a physical address. Visitors register with the visiting officer, may be searched, must follow dress and conduct rules, and cannot bring drugs or alcohol. The county also warns that inclement weather may cancel visitation with little or no notice, so confirm before traveling when public-service cancellations are possible.

The county visitation page is the matching source for the appointment and weekend schedule rules shown here.

Because appointment rules can affect whether a visitor is admitted, confirm the schedule with the detention center before relying on an older saved copy of the rules.

Mail, Phone, and Money at Calvert County Detention Center

Calvert's jail mail rules are unusually specific. Mail must come through the U.S. Postal Service only; visitors may not drop off mail. Incoming handwritten mail must be in pencil or blue or black ink on white, plain, or lined paper. The envelope must show the sender's full name and physical street address. A post office box alone is not enough, and return-address labels are not accepted. The research also notes no greeting cards, no colored or tinted paper, and no Polaroid or Instamatic photos.

Money orders may be mailed if made payable to CCDC and marked with the inmate name plus the sender's name, address, and phone. Cash and checks should not be mailed. The lobby kiosk accepts cash and credit cards 24/7, with a transaction fee deducted, and deposits are added immediately. The county also links JailATM for online deposits. Commissary orders are placed on Wednesday through the inmate telephone system and delivered Thursday when the inmate has enough funds. Phone accounts are handled through Paytel, with customer service at 800-729-8355.

Booking and Intake at Calvert County Detention Center

Calvert's public pages do not publish a complete booking manual, so the reliable description has to stay tied to the facility's stated role and the sheriff's quarterly data. After an arrest or warrant service, a person committed to jail custody may be transported to the detention center for identity confirmation, property inventory, booking record creation, medical and mental-health screening, photographs and fingerprints when required, review of court or warrant paperwork, release-condition processing, classification, and housing assignment.

The Sheriff's Q4 2025 report supports that this is an active intake operation: it reported 376 new inmate intakes or bookings and 373 releases during the quarter. It also reported 376 mental-health service intakes, 198 enrolled in mental-health services, 100 receiving psychotropic medication, 26 intakes requiring detoxification, and four emergency hospital transports. Those figures support discussion of medical, mental-health, and detox processing without inventing a specific local screening form.

Property release is handled separately. The official property-release page says inmate property can be released Monday through Friday, 8 a.m. to 4 p.m.; arrangements should be made before pickup; and photo identification is required before property will be released.

Facility History, Programs, and Community Supervision

The official jail history page places the modern facility in a longer courthouse-centered jail history. Until the early 1950s, the jail was in a separate building behind the courthouse. It later moved into the courthouse with three holding cells and space for 14 inmates. Because that facility became antiquated and overcrowded, the county opened the Barstow jail on September 5, 1978, with six work-release inmates and 20 maximum-security inmates. The 1992 expansion created maximum, medium, and minimum housing areas and renamed the facility Calvert County Detention Center.

The history page is also a useful source for understanding why the current jail is more than a single holding area.

Read the county's detention center history page.

The expansion history explains why Calvert's current jail records may involve different housing classifications and why the Work Release Building is treated separately from the main custody units.

Program services are provided for both male and female offenders. The county describes in-house programs supported by community volunteers for counseling and education based on inmate ability and need. The Community Supervision Unit also covers home detention, pretrial release, and work release. Home detention and pretrial release require court authorization or court order, and work release is for sentenced offenders with court-recommended work-release commitments.
