Volunteer for Open House Chicago

We’re thrilled to involve over 1,000 volunteers to greet and assist visitors at 200+ sites throughout the city.

Between October 17-18, 2026, OHC Volunteer Greeters work ONE shift either Saturday or Sunday, for 3.5-5.5 hours.

As a thank you, each volunteer receives great benefits, including a Priority Access Pass which lets you skip long lines.

Volunteer registration will open early summer 2026.

The team at the CAC thanks you for being dedicated to our city and our festival. Please email ohcvolunteers@architecture.org if you have questions about this process.
