This ordinance names the office building at 30 N. LaSalle St. an official Chicago Landmark. The building, finished in 1974, replaced the Chicago Stock Exchange Building, and its construction is tied to the start of Chicago's historic preservation movement. All outside walls and rooflines are protected, but some already-approved renovation plans are still allowed.
- The building at 30 N. LaSalle St. becomes a Chicago Landmark; the Commission on Chicago Landmarks recommended this on January 8, 2026.
- It replaced the 1894 Chicago Stock Exchange Building by Adler and Sullivan, whose demolition helped launch the city's preservation movement.
- It was designed by Dallas architect Thomas E. Stanley II, his only Chicago building, mixing International Style and New Formalism.
- All exterior walls and rooflines are protected features for future permit reviews.
- Renovations approved in March and August 2025 are still allowed, including turning the building into residential and office use with ground-floor retail, new windows, storefronts, a canopy, and a rooftop addition.
Who: The owners and developers of 30 N. LaSalle St. are affected, since exterior changes will need landmark permit review, though their previously approved 2025 renovation plans may go forward.
Where: 30 N. LaSalle St., Chicago, Illinois (ward not stated)
