The mall has a Happy Valley, Oregon, mailing address, but is actually located in an unincorporated area.

The two level enclosed mall, with of retail space officially opened on March 6, 1981, built by Ernest W. Hahn, Inc. Prior to the mall's opening, the attached Meier & Frank store opened in October 1980. which opened in November 1981 and by 1985 was being used by six bus routes. In the 1990s, Olympic skater Tonya Harding frequently practiced on the ice rink. The mall remained largely unchanged until Montgomery Ward went bankrupt and closed its store in 2001. Meier & Frank acquired the former Ward building and opened a home store in 2002 in the upper level, while leasing out the lower level to Copeland Sports. The ice rink closed in 2003, the original movie theater closed in 2005, and Copeland in turn closed in 2006. Macy's reclaimed the former Copeland's space and expanded the home store into that space.

General Growth Properties acquired a 50% interest in the property in 2002 and assumed management. A major redevelopment began in 2005 to add to the center. As part of the construction the area formerly occupied by the ice rink was gutted, and the Carter sculptures were removed. Designed by architectural firm DLR Group, the renovation and expansion added approximately 40 new stores and restaurants, many in a new lifestyle center on the south side, and a new , 20 screen Century multiplex theater. The renovation also put in tranquility ponds, new flooring, lighting, furniture, escalators, elevators, handrails, and exterior upgrades. It was completed in late 2007. The new, larger movie theater opened in December 2007. In September 2009, a new MAX Light Rail station opened at the mall, with the opening of the Green Line. The Clackamas Town Center Transit Center station is the southern terminus of the Green Line and is located on the east side of the mall's parking area. It is also served by several bus lines and it replaced the original transit center, which had closed in 2006 and temporarily been replaced by simple bus stops pending construction of the new facility.
