College Nine is composed of three residence halls (R1, R2, and R3); in the spring of 2006 the residence halls were renamed to emphasize and reflect the college's theme. As of Fall 2006, the new residence hall names are Hague House, Gandhi House, and Geneva House. These names however are temporary names and are subject to change once the college finds a benefactor. ^{[citation needed]}

In the LRDP (Long Range Development Plan) for UCSC, Colleges 9 and John R. Lewis will be situated as the very center of UCSC by 2025.

College Nine is also home to the International Living Center (ILC). The ILC is home to nearly a third of international students visiting UCSC while on study abroad and provides a space where international, transfer and domestic students coexist in apartment-style living. There also exists three International RAs as well as its own Coordinator for Residential Education.
