Lessen Relocates Chicago Office to 203 North LaSalle Street 

Lessen, an Arizona-based real estate software company, will relocate its Chicago office to 203 North LaSalle Street, a 17-story, Class A office building in the city’s Central Loop tech district.

Lessen has signed a lease for 77,000 square feet in the building owned by Sumitomo Corporation of Americas, which is across the street from the James R. Thompson Center. JLL‘s Brian Means and Jake Ehrenberg represented the tenant. Transwestern’s Eric Myers, Kathleen Bertrand and John Nelson manage leasing at 203 North LaSalle.

In 2023, Lessen acquired SMS Assist, a facilities maintenance technology company headquartered in Chicago, marking Lessen’s corporate entry into the local market. “When we acquired SMS Assist last year, its founder Mike Rothman told me that Chicago is the greatest city in the country,” said Lessen CEO Jay McKee.

Lessen cited Google’s pending move to Thompson Center as a motivation for the firm’s relocation to the heart of the city’s tech hub. “Google’s announced move into the Central Loop is establishing LaSalle Street as a premier tech corridor within Chicago, and this location situates us perfectly for the next chapter of our corporate expansion,” said McKee.
