399 Fremont Street is a 122 m (400 ft) residential skyscraper in the Rincon Hill neighborhood of San Francisco, California.

[3] On June 15, 2006, the San Francisco Planning Commission approved the demolition of the existing buildings and the construction of a 400-foot (120 m) residential tower by developer Fifield Realty Corp.

Initially designed by Richard Keating Architecture, the development was approved for 432 residential units with 432 parking spaces in four underground levels.

[7] After two years without starting construction, the Planning Commission granted a 12-month extension of its approvals until June 15, 2009.

[4] According to planning documents, the building will rise 400 ft (120 m) to the roof line, exclusive of mechanical screening structures, which makes the tower's total height somewhat taller.
