The City Administration Building (aka "2 Frank Ogawa Plaza") is a steel frame Postmodern office building on a double frontage lot extending from Broadway to the former line of San Pablo Avenue on Frank Ogawa (City Hall) Plaza. The building is seven stories on the south, five stories on the north, clad in concrete and stone panels, an irregular trapezoidal plan with a rounded bay at the northwest corner. It is internally connected to the Broadway Building (1401-19 Broadway), part of the City Administration Complex. Its floor heights match the Broadway Building, and has Postmodern cornices of pipes and metal brackets alluding to and aligned with the cornices of the Broadway Building.

Designed by architects Fentress Bradburn & Associated, the building was constructed by Hensel Phelps Construction Company in 1997.

This building occupies the site of three earthquake damaged and demolished buildings on the 1400 blocks of Broadway and San Pablo Avenue between the Broadway Building and the Rotunda (Kahn's Department Store).  It is one of two new City office buildings constructed north and east of City Hall in 1997.

This historic building is #58 on the list of District Contributors/Noncontributor for the Downtown Oakland Historic District Registration Form. The City Administration Building is a non-contributor.
