An Iconic City. An Iconic Project. A World Class Experience.

The Moscone Expansion project is an extraordinary effort by the City, the San Francisco Tourism Improvement District Management Corporation, and the hotel industry to expand our existing convention space. While it is one of the most successful convention centers in the United States, Moscone Center is operating at capacity and is losing business to competing markets with more space to offer. In order to continue to attract the best and brightest events to San Francisco's convention market, we plan to increase our capacity and contiguous space.

Tourism is the single biggest contributor to San Francisco's economy and Moscone Center is responsible for 21% of it. This project serves to safeguard the myriad of benefits brought to line-service employees, San Franciscans, and our city at large by guaranteeing our ability to meet demand for years to come. The increases in hotel tax revenue, job creation, and the general positive economic impact of this project will serve the needs of all San Franciscans and visitors alike.

To keep up with current construction activities, please see our LIVE CAMERA.

Project Location
The proposed project site includes a limited portion of Moscone North and Moscone South, with approximately half of the work being done underground in order to better connect the two buildings. No work will take place at Moscone West or east of Third Street.
