Simon Property, which has seen the future of brick-and-mortar retail seriously threatened by the pandemic, plans to open the shopping centers between Friday and Monday. The majority are in Texas, Indiana, Georgia and Missouri. Properties in Tennessee, South Carolina, Oklahoma, Arkansas, Alaska and Mississippi will also be reopened.

Simon Property, which is based in Indianapolis and at the end of last year owned more than 200 properties in 37 states and Puerto Rico, did not respond to requests for comment.

It is not clear how many retailers with stores in those malls will open their doors. Gap Inc., which owns its namesake brand as well as Athleta, Banana Republic and Old Navy and is a tenant in some of the properties being reopened, said on Tuesday that it was not opening any stores this weekend. Macy’s, also a Simon Property tenant, currently has all of its stores closed. On Tuesday, it said it had no update on when they would reopen.

Simon Property’s memo, which was first reported by CNBC, emphasized the safety protocols it was enacting as it started to invite customers to malls. Simon Property’s employees, contractors and vendors will be required to take their temperature before work, and stay home if they have a fever of 100.4 degrees or higher or exhibit flulike symptoms, the documents said. They will also wear face masks and aim to stay six feet away from others. The mall operator said it would provide free temperature testing, masks and sanitizing wipe packets to shoppers upon request, and that they would be “encouraged” to wear face masks and wash their hands frequently.
