General Visiting Rules

All visitors are subject to canine, electronic drug detection device, and/or visual mouth searches prior to being allowed to visit an inmate.  In addition, all visitors are fingerprinted using a single digit fingerprint scanning device (Web ID software).  

If the Web ID system indicates a “hit” (which only indicates that the visitor has fingerprints on file for either criminal or non-criminal purposes), the visitor will be provided with a letter which explains that the visitor did not clear the fingerprint identification process and what is necessary to proceed.   

After the visitor submits the required information,  the warden will advise the visitor (in writing) as to whether or not their visiting privileges have been approved or denied. 

If visitors cannot clear the metal detector, they will be denied entry. Nothing may be brought into the institution except as authorized by the warden or designee. Any item brought into the institution in a manner other than authorized is contraband, and the person bringing the item into the institution is subject to criminal penalties. 

All visitors (16 years of age and older) must have a photo ID.

Children (18 years of age and younger) visiting the inmate must be immediate family to either the inmate or visitor and must be accompanied by a person 18 years of age or older who is on the inmate’s visiting list.

Use of restroom facilities is not allowed during visitation. If either the inmate or a visitor requires the use of the restroom, the visit will be terminated at that time. Please keep this in mind when visiting with small children.

Visitors should enter through the Greenmount Avenue and Madison Street entrance. Visitors will not be permitted to register after the cut off times listed above. 

Inmates will only be allowed legal and clergy visits for the first 45 days of their stay.  After the first 45 days, inmates may receive two social visits per weekend for the remainder of their stay at MRDCC. Once an inmate is assigned to CADRE, they are permitted to have visits immediately regardless of whether or not they have been at MRDCC for 45 days.

No more than three visitors, including children, may visit at any one time. Toddlers and children are included as visitors.

Dress Code

All visitors, including children, must dress appropriately for visitation.  All clothing must cover you from the neck to the kneecaps.

The following types of clothing are not allowed to be worn:

  • tube tops, tank tops, or halter tops
  • see-through clothing
  • mini-skirts, mini-dresses, shorts, skorts, or culottes (at or above the kneecap)
