Volunteer for Open House Chicago

We’re thrilled to involve over 1,000 volunteers to greet and assist visitors at 170+ sites throughout the city.

Between October 18-19, 2025, 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.

We will begin registering volunteers for OHC 2025 in July. Add your email address below to be notified when registration opens. 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.
