Why Is McCormick Place Important for Chicago Exhibitors?
McCormick Place is the largest convention center in North America, with 2.6 million square feet of exhibit space across four buildings — the North, South and West Buildings and the Lakeside Center — including 1.2 million square feet on a single level. The campus also holds more than 170 meeting rooms totaling roughly 600,000 square feet of meeting space, six ballrooms, and ceiling heights up to 50 feet in the exhibit halls, which matters for hanging signs and trusses on larger island exhibits. The venue draws close to 3 million visitors a year and hosts some of the country's largest recurring trade shows, including IMTS (September 14–19, 2026), PACK EXPO International (October 18–21, 2026), RSNA's Scientific Assembly and Annual Meeting (November 29–December 3, 2026, with technical exhibits running through December 2), and The Inspired Home Show (March 9–11, 2027).
Every one of those shows runs on rules set by its own show organizer, not by a single blanket McCormick Place policy. Height limits, rigging permissions, electrical drops, fire-marshal requirements, and labor jurisdictions are defined hall by hall and event by event in that show's exhibitor manual — this is why we ask for your specific hall assignment and manual before quoting, rather than reusing a generic Chicago booth spec.
A few things stay consistent across McCormick Place shows: exhibit hall labor — carpenters, electricians, riggers, decorators, and material handling — is performed by union trades hired through your show's Official Service Contractor (OSC), the general contractor your show organizer appoints. Exhibitors can also work through an Exhibitor Appointed Contractor (EAC) for design and supervision, provided that contractor is properly registered with the OSC and carries a Certificate of Insurance meeting the show's requirements. ADA accessibility, fire-retardant material standards, and freight/material handling documentation are typically spelled out in the same manual. We do not hold Official Service Contractor or approved-contractor status at McCormick Place, and we don't imply otherwise — we work within whatever OSC and labor structure your specific show requires.
