The office building at Geneva Yard was designated a San Francisco Landmark by the San Francisco Board of Supervisors in 1985 . After being damaged in the 1989 Loma Prieta earthquake , the office building and powerhouse were red-tagged and abandoned . In 1998 , Muni planned to demolish the structures to create a parking lot ; the agency dropped the plans the next year due to community opposition and the intervention of mayor Willie Brown . The nonprofit group Friends of the Geneva Office Building ( later Friends of the Geneva Car Barn and Powerhouse ) was formed with the intention of instead renovating the buildings for community use
