San Clemente is a grad student complex with surplus rooms alotted to undergrads. The atmosphere is a bit too “dormy” for most grad students after their first year. The majority of UCSB undergrads end up sharing rooms with other students in Isla Vista where rents are astronomical and housing quality poor. If you want your own room as an upperclassman expect to pay $1000/month and up in a multi bedroom apartment. Some of the nicer apartment complexes effectively bar renting to undergrads by requiring proof of income and refusing co signers. Until more housing is built the best option is to stay in university housing all 4 years.
