Melvin Simon & Associates built Jefferson Valley Mall in 1983, which included Sears and Read's (later Jordan Marsh, then Abraham & Straus, now Macy's). Expansion plans were announced in 1996. These were to comprise the addition of 80,000 square feet to Macy's and an additional anchor. Service Merchandise, another mall tenant that closed in 1999, became H&M in 2001. In the early  2000s the mall went under a renovation changing the flooring and color along with removing the fountain and trees. In February 2016, the mall ownership was changed from Simon to Washington Prime Group. Construction is underway to expand and renovate the mall. On October 15, 2018, it was announced that Sears would shutter. It is set to be reconstructed to feature additional mall space.
