Spend two days getting a behind-the-scenes look at over 200 fascinating architectural sites — many of which are usually closed to the public — during Open House Chicago, held in neighborhoods across the city from Oct. 18 – 19, 2025. This architectural event, hosted by the Chicago Architecture Center (CAC), is one of the largest of its kind in the world.
For the 15th year, more than 35,000 people will explore sites in 25 diverse neighborhoods. All locations were selected for their architectural, historical, and cultural significance. By making learning about architecture accessible to all, Open House Chicago aims to inspire people to discover why design matters. The event also showcases businesses, organizations, and creative leaders who make a positive impact on the city.
“With all the new developments happening or proposed in Chicago, it’s more important than ever that people see how architecture and design shape our city,” said Eleanor Gorski, CEO and president of the nonprofit CAC. “Open House Chicago is easily accessible and free to all. We hope the event fosters dialogue about architecture and inspires people to become more actively engaged in shaping and improving our built environment.”
During Open House Chicago, shutterbugs can take photos that might win a competition. Snap images that match five categories — interior, exterior, black and white, detail, and people and buildings — and submit them to the CAC. Selected images will be displayed in the Framed Views: OHC Photography exhibition that opens at the CAC in November 2025 on a date to be announced.
CAC members will receive an Open House Chicago priority access pass, allowing them to skip lines at sites. Find out how to join the CAC. To start building your own Open House Chicago weekend itinerary, visit CAC’s website or download the CAC app.
The featured sites for Open House Chicago will be announced in mid-September via @chiarchitecture on Instagram.
