Chase Center is a state-of-the-art venue on an 11-acre site in San Francisco’s Mission Bay neighborhood. The privately-financed project includes a state-of the-art 18,000-seat arena, two office buildings, 100,000 square feet of mixed-use/retail space, and underground parking. More than three acres -- 30 percent of the site -- will be plazas, landscaping and other public spaces.
