Salesforce Tower

Salesforce Tower, formerly known as Transbay Tower, is a 61-story skyscraper at 415 Mission Street, between First and Fremont Street, in the South of Market district of downtown San Francisco. Its main tenant is Salesforce, a cloud-based software company. The building is 1,070 feet (326 m) tall, with a top roof height of 970 feet (296 m). Designed by César Pelli and developed by Hines Interests Limited Partnership and Boston Properties, it was the last building designed by Pelli to be completed in his lifetime. As of 2024, Salesforce Tower is the tallest building in San Francisco and the second-tallest building both in California and west of the Mississippi River after the 1,100 feet (335 m) Wilshire Grand Center in Los Angeles.

Salesforce Tower is obelisk-shaped, with a grid of metal fins running from the base of the building to the roof. The building sits on a land fill, and multiple load-bearing pillars reach below the foundation and into bedrock. The exterior of the building consists of a glass and steel curtain wall with a steel frame and a concrete core. Each floor of the building uses brises soleil to deflect sunlight. Salesforce Tower is designed to be a green building, with the building employing water conservation measures and air intake systems. A public art light sculpture at the top of the building, consisting of 11,000 LEDs, displays video animations every evening that can be seen from up to 30 miles away.

What is now the Salesforce Tower was planned as part of the San Francisco Transbay development, a redevelopment plan for the area surrounding the Transbay Transit Center. The plan was adopted by the city in 2005. In 2011, the San Francisco Transbay Terminal was completely demolished, beginning the plan, and in 2013, construction on the building began. Salesforce Tower was completed in 2018 for over $1.1 billion. By 2019, Boston Properties had acquired a 100% stake in the property.
