50 California Street

50 California Street is a 37-story tower in the Financial District with vertical precast concrete columns, black spandrels, and grey glass panels creating a linear pattern on its facade. The building rises prominently above street level and houses office spaces designed for corporate tenants.

The tower was completed in 1972 by Welton Becket and Associates as a major addition to San Francisco's downtown. This project was part of the broader development that reshaped the financial sector during that era.

The building represents a central component of San Francisco's financial sector, hosting numerous corporate offices and financial institutions within its commercial spaces.

The building contains 17 elevators and operates digital systems that manage ventilation and temperature throughout. Access is primarily limited to office tenants and their guests, as it is a private commercial space.

The tower achieved LEED Platinum certification in 2016 and reduced its annual energy consumption by about one-third through technological upgrades since 2008. These improvements came from advanced building management systems rather than structural changes.
