<P> On April 19, 2014, the Warriors abandoned plans for the pier site and purchased a 12 - acre site owned by Salesforce.com at the Mission Bay neighborhood for an undisclosed amount . The arena project will be financed privately . The architect for the project is MANICA Architecture and the current plan for Chase Center is to have it built by 2019 before the NBA season starts . The plan for Chase Center to open earlier was pushed back multiple times due to many complaints about the location . Construction on the arena began in January 2017 . </P> <P> In April 2015, the Mission Bay site was opposed by the Mission Bay Alliance, which cited traffic, lack of parking, and use of space that could go to UCSF expansion among other things as their reasons for opposition . Their complaint is that Chase Center will be located near UCSF Benioff Children's Hospital and AT&T Park and will create more traffic in San Francisco . Others say that this area can be used to expand the campus of UCSF . To avoid the plan to build Chase Center being voided, representatives of the project have been working to address these issues such as traffic and parking . </P> <P> The Golden State Warriors had the official groundbreaking ceremony for Chase Center on January 17, 2017 . </P>
