Living on campus is often the best option for postdocs, especially when you first come to the Bay Area. Advantages include:
Space in campus housing is limited. Apply as soon as possible.
Want to live off-campus? UCSF partners with Places4Students.com to list housing opportunities near campus. The most commonly used online resource for finding apartment rentals in the Bay Area is Craigslist.org. (Craigslist is not affiliated with UCSF in any way.) See also a list of other Bay Area housing-related websites.
Whether you live in San Francisco or in the greater Bay Area, good public transportation systems (e.g. BART, CalTrain, and AC Transit) make it feasible for many postdocs to live off-campus, while still having reasonably short commutes and keeping costs down.
