The University Cooperative Housing Association (UCHA) is a student housing cooperative in Westwood, Los Angeles near the University of California, Los Angeles (UCLA) campus. Able to house and feed over 400 members, the UCHA primarily offers housing to UCLA students, but welcomes members from any institution. The UCHA operates three buildings: Hardman-Hansen Hall (HHH or "Triple H"), Essene Hall, and Robison Hall. Jim Morrison of The Doors purportedly lived at the UCHA during his time at UCLA. Green Day and Margaret Cho performed at the UCHA in the early 1990s. Alongside the UCLA campus, Hardman-Hansen and Robison Halls were used as filming locations for the 1982 horror film, The Dorm That Dripped Blood. Many students of China's Lost Generation studying at UCLA resided at the UCHA.
