Research Housing
The university offers a number of housing options for law students:
Campus housing (academic year)
This site has lots of information about graduate student housing, including family housing. Some of the most popular on-campus housing for LLMs include the Manville Apartments, Ida Louise Jackson House and International House.
Campus housing (summer)
In addition to the dormitories that are available during the summer, Manville Apartments allows academic year students to sublet their apartments during the summer.
Alternative housing
The Berkeley Student Cooperative consists of 20 student-run houses and apartment buildings, where members contribute a few hours of work each week in exchange for relatively cheap room and board. Craigslist.org and Cal Rentals can be good sources of information on private rooms and apartments for rent in the local community.
