The Utah entrepreneur, who joined RSL's ownership in 2009 and served as the organization's vice chairman and alternate governor, has now taken full ownership from club owner Dave Checketts.
"Just over three years ago, I was very proud to join Dave Checketts in the world of Real Salt Lake and Major League Soccer," Hansen said in a club statement.
"Today, the chance to further deepen my participation in the growth of professional soccer in North America is incredibly exciting. My enthusiasm for this sport started long ago with my family, and now I am proud that our investment now includes the entire Real Salt Lake family - starting with our incredible fan base - as we work together representing the great State of Utah."
Checketts added: "The last eight years have been a labor of love. When we started I made a promise to build something of meaning; something that people in my home state of Utah could be proud of.
"Real Salt Lake has become much more than a soccer team, and Rio Tinto Stadium much more than a venue. Each has become integrally woven into the fabric of this community and become beloved assets to the people here. It is a legacy that I will forever take pride in, and I am happy to leave it in local hands. I know that Dell Loy will be a tremendous caretaker for the Team, the Stadium and all that both represent."
