South Mountain Arena originally opened in 1958 with the second, smaller rink added in 1983. During 2004 and 2005 the arena underwent major renovations that included a new state-of-the-art lobby for the arena including meeting rooms, a skylight, automatic doors, pro shop, arcade, and concession stand. Another part of the renovation was a new set of dasher boards, Plexiglas, compression system, jumbotron screen, and seats for Rink 1, as well as a new dehumidifier for Rink 2; it was renamed the Codey Arena upon reopening. In 2017, management announced that Rink 1 would undergo renovation once again putting in new seats, new boards, and a new jumbotron/scoreboard. In the fall of 2018, the arcade was replaced by vending machines.
