The Berkeley Student Cooperative (aka University Students' Cooperative Association or USCA) is a student housing cooperative serving primarily the University of California, Berkeley but open to any full-time post-secondary student. The BSC houses over 1300 students in 20 houses and apartment buildings. Residents of the houses are expected to perform work (about 5 hours a week) as part of their rental agreement; the work helps to keep the rent lower. The BSC is led by a board of directors elected by the residents. The BSC is a member of NASCO.
