Salesforce East is a skyscraper in the South of Market district of San Francisco, California. Current designs call for 30 stories and 455 ft (139 m) above street level.[5][6] Upon completion, the building plans to attain LEED Gold status.


350 Mission Street is located at the northeast corner of Fremont Street and Mission Street in a part of the South of Market district typically considered an extension of the Financial District. It is located near several other downtown skyscrapers, including the adjacent Blue Shield of California Building and 45 Fremont Street. Across Fremont Street to the west is 50 Fremont Center, and across Mission Street to the east is Millennium Tower. To the south, at the opposite corner of the intersection is the site of the Transbay Tower. It is located a block from Market Street and a half block from the new Transbay Transit Center.


The first version of the project was initially proposed at 850 ft (259 m) with 1,000,000 sq ft (93,000 m2) of office space, but the developer reduced the project height by 300 ft (91 m) and the floor area by over 600,000 sq ft (55,700 m2).[4][8] This was because the first version of the project exceeded the local height limit by 300 ft (91 m).[4][9]

The second version of the project was compliant with the local 550 ft (168 m) height restriction.[9] Even though the city of San Francisco released a zoning plan that allowed the tower to rise as high as 700 ft (213 m) on May 1, 2008,[10] the developer the reduced size of the project to 375 ft (114 m) about two months later. The third version stood significantly shorter than the proposed height limit because the developer stated that it was uneconomical to build any taller on a 19,000 sq ft (1,800 m2)-sized lot.[11] The square footage of the building increased slightly to 350,000 sq ft (33,000 m2), up from 340,000 sq ft (32,000 m2).[6]

In October 2012, GLL Development & Management sold the project to Kilroy Realty for US$52 million.[12] In December 2012, Salesforce.com agreed to lease the entirety of the proposed tower, and Kilroy sought to add an additional six stories to the proposed 24-story tower, increasing the office space to 420,000 square feet (39,000 m2).[5][13] In February 2013, demolition started on the site's existing four-story building, formerly the home of Heald College.[14] On August 15, 2013, the S.F. Planning Commission officially approved the height increase to 30 stories.[15] Kilroy plans to deliver the tower to Salesforce.com in 2015.[16]
