Phoenix Suns Arena is undergoing the second significant renovation in its history. The Phoenix City Council approved the plan on January 23, 2019 involving the arena, with the Phoenix Suns paying up to $80 million alongside any overrun costs. The first renovation was completed in March 2003 that had an air conditioned glass-enclosed atrium built on the northwest side of the arena. That $67 million project was constructed to keep patrons cool while waiting in line for tickets or spending time inside the building before events. The arena upgrades have been done as part of the Suns' plan to keep it economically competitive after Gila River Arena opened. Former Suns owner Jerry Colangelo originally thought of the renovations after visiting Staples Center in Los Angeles and envisioned a similar entertainment district in Phoenix.
