The Coliseum underwent a major renovation and restoration program from 2017 to 2019.[61] A new press box, loge boxes, and club seats were installed.[62][63] Crypto.com Arena underwent renovations completed in 2024,[64] and the NBA's Los Angeles Clippers opened a new arena in Inglewood known as Intuit Dome in August 2024;[65] venue for basketball during the Games.[66]
To reduce costs and use more pre-existing facilities, LA28 announced changes to its venue plans in June 2024. The temporary aquatics venue that was scheduled to be built at USC's Dedeaux Field was scrapped, in favor of holding swimming at SoFi Stadium and artistic swimming in Long Beach. Diving was originally set for the historic LA84 Foundation/John C. Argue Swim Stadium (which was built for the 1932 Games) but was later changed to the Rose Bowl Aquatic Center in Pasadena due to cost and safety concerns in September 2025.[67] With a planned configuration for 38,000 spectators, SoFi Stadium will be the largest swimming venue in Olympic history. Equestrian will return to Santa Anita Park once again, as Arcadia had previously hosted the event in 1984, while softball and canoe slalom were moved to existing venues in Oklahoma City, Oklahoma, instead of building new venues in Los Angeles County.[4][5][57]
