19 South LaSalle Street was constructed as the Central YMCA Association Building in 1893,[1][2] and completed shortly before the Panic of 1893.

[3] Modern-day 19 South LaSalle Street is owned by Cloverfield, Inc. and operated by Colonnade Management, Inc. as a mixed-use retail and office building.

[4] Law offices and companies such as Vivid Ascent, an integrated marketing firm, and Sprint, which has a retail location in the building, operate out of 19 South LaSalle Street.

[5][6][7] 19 South LaSalle Street has been described as one of Jenney's most "uncompromising" facades due to its rectangularity which is only interrupted by horizontal banding at the 11th and 12th stories.

[8] Although, the horizontal courses and the building's shifting design are typical of Jenney's work around this time period.
