Statewide rules that apply at every Maryland state prison

These rules are set by DPSCS and apply at every unit. The full list — including all permitted and prohibited items and the approval process — is in Visiting in Maryland.

Dress code

Dress modestly — no revealing, sheer, or provocative clothing, and nothing that resembles what incarcerated people or staff wear.
Each facility enforces its own visiting dress code and may turn away a visitor who is dressed out of code, so confirm the specific facility's rules before traveling.

ID: Every visitor must be on the incarcerated person's approved visitor list, and visitors 16 and older show a valid government-issued photo ID. The incarcerated person generally must serve about 30 days before visits can begin.
What to bring: Bring only what the facility allows — phones, bags, and most personal items are not permitted; a small amount of cash in $1 bills is allowed only where a vending machine is available. Money for the person's account is sent through Access Corrections, never handed over at a visit.
Scheduling: Visits are by appointment arranged with each facility (often by email) and confirmed in advance — Maryland has no single statewide online scheduler, and days and hours vary by facility. Maryland also offers free video visits through Microsoft Teams. A newly committed person is processed at a reception/classification center first — women at the Maryland Correctional Institution for Women; men's intake is in transition, so confirm the current location.
