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. 17 – 18, 2026. This architectural event, hosted by the Chicago Architecture Center (CAC), is one of the largest of its kind in the world.

For the 16th year, more than 35,000 people will explore sites in 30+ 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 better living through design. The event also showcases businesses, organizations, and creative leaders who make a positive impact on the city.

“Chicago’s architecture tells the story of who we are as a city, from the landmarks that put us on the map to the neighborhood spaces that shape our lives,” said Eleanor Gorski, CEO and president of the nonprofit CAC. “Open House Chicago wants to change the way you see the city. We hope visitors check out a new neighborhood or finally step inside a place in their own neighborhood they’ve only walked by previously. Our goal is to make everyone more engaged and proud to be a Chicagoan.”

During Open House Chicago®, shutterbugs can take photos that might win a competition. This year, the theme of the competition is celebrating Chicago’s diverse neighborhoods. Participants of all ages and skill levels are encouraged to submit images of sites across the 30+ neighborhoods in this year’s festival. Selected images will be displayed in the Framed Views: OHC Photography exhibition in the Chicago Gallery at the CAC.
