Parties in Berkeley College involving alcohol require, in addition to all requirements noted in the Undergraduate Regulations, a returnable $50 damage deposit, payable to the Head of College’s Office, at least two working days in advance of the party. Host’s cell phone must be set on vibration during party, and must be on the host’s person and answerable throughout party. If host cannot be reached by cell phone by the Head of College, the Dean, or one of the Resident Fellows during the party, the party will be shut down and the deposit retained. Hosts with any reasonable expectation that more than 50 guests might attend the party must engage an off-duty police officer from the Yale Police (2-4400).
