The building was placed on the National Register of Historic Places in 1983.
The design for the Oakland City Hall resulted from a national competition. It is clad in white granite and terra cotta. There are three set-back sections: a 3-story podium, a 10-story office tower, and a 2-story base supporting a 91 ft. ornamental clocktower donated by onetime mayor Dr. Samuel Merritt.
Following the Loma Prieta earthquake of 1989, the Oakland City Hall became one of the largest buildings to be seismically separated from its foundations - an outstanding feat of engineering.
