Students and student organizations are responsible for the behavior of their guest(s) while they are on property owned or controlled by the university or in attendance at its sponsored events. The host student or student organization assumes full responsibility for the guest compliance with all prescribed university policies and procedures, including those specific to residence hall visitation.

Residence hall students are allowed to have guests under the following policy:
The visitation policy allows for 24-hour visitation on all floors in the residence halls. All guests must check-in and comply with the guest policy. Main campus students must register as guests at Aquinas Hall, and Aquinas students must check in as guests when visiting the main campus. All non-DU guests must present a government issued picture ID. Dominican University commuter students must present their Student IDs. The host student must escort his/her guest(s) at all times. Guests under 16 years of age are exempt from showing ID, but must be checked-in. University officials, members of law enforcement and/or other approved personnel are allowed in the residence halls without checking in or having a host.

The 24-hour visitation policy has several conditions:
• A resident must have the agreement of his/her roommate in order to host a guest.
• No cohabitation is allowed. Individuals not assigned to the room may not live in the room. Members of the opposite sex are not allowed to “live” or stay as overnight guests.
• Guests may stay in the residence halls for a maximum of three nights per three-week period. Residents and guests abusing this policy will forfeit the privilege of having guests.
• No one under the age of 12 is allowed in the residence halls after 8 p.m. and before 8 a.m.
• Residents must acquaint their guests with all university and residence hall policies. Residents will be held responsible for the actions of their guests and/or anyone checked in under their name.
• Residents must escort their guests at all times, including when guest is leaving the residence halls and checking out. This includes escorting guests in and out of the building. Guests who are not escorted by their hosts may be asked to leave the hall. A resident student may have no more than three guests at one time.
