San Francisco City Hall unexplained reports

San Francisco City Hall, rebuilt after the 1906 earthquake, is cited in local tour guides and newspaper features for occasional reports of unexplained footsteps, sightings, and strange noises in offices, corridors, and older portions of the structure. These reports appear in oral histories, ghost-tour material, and press coverage; they are anecdotal and subject to differing interpretations. City Hall is a documented civic building with well-recorded architectural and political history tied to the city.
