100 Van Ness Avenue is a skyscraper in San Francisco  undergoing a conversion from office to residential use. It is located in the Civic Center  neighborhood near the  San Francisco City Hall on Van Ness Avenue . The building, completed in 1974, stands 400 feet (122 m) and has 29 floors of former office space that housed the California State Automobile Association .

The building was sold by CSAA to VNO Patson, LLC in 2008 and was leased back to CSAA until 2010, at which time they relocated to a new corporate headquarters campus near Walnut Creek.  VNO Patson’s interest in the building was foreclosed on by its lender and is now owned by Civic Center Commons Associates, which took title to the property in 2011. The new owner is planning a conversion of the building to 400 rental apartments. Construction on the new apartment tower is expected to be completed by 2015.
