Unlike most other major art museums, the Fine Arts Museums of San Francisco do not have a large endowment from which to draw. The museums operate on an annual budget funded by membership dues, ticket sales, donations (from philanthropy and grants) and purchases in its stores.[1] They are run in a private-public partnership with the city of San Francisco, which owns the two museum buildings and covers about 23 percent of their operating expenses by providing security guards and paying insurance premiums.
