About Open House Chicago

Every October, the Chicago Architecture Center is proud to host Open House Chicago—a free public festival that offers self-guided history and architecture trails throughout Chicago, talks and programming, and behind-the-scenes access to architecturally, historically and culturally significant sites across the city.

Open House Chicago remains one of the largest events of its kind in the world. This year, Open House Chicago's in-person site visits will occur on October 14 and 15. Additional plans for OHC 2023 include the OHC app, virtual programs and special programming.

In 2023 we will highlight more than 20 Chicago neighborhoods, 150 sites, outdoor exploration on themes of neighborhood investment, community engagement, historic preservation and more. You will also find tips and itineraries for exploring shopping, dining and other attractions in each neighborhood.

What is Open House Chicago?

Open House Chicago (OHC) is a free annual festival hosted by the Chicago Architecture Center that offers behind-the-scenes access to buildings of architectural, cultural and historical significance during one weekend in October.

Who organizes Open House Chicago?

Since 2011, the Chicago Architecture Center (CAC) has produced each Open House Chicago festival. The CAC is a nonprofit cultural institution that offers tours, exhibitions, programs and events for all ages. The CAC’s mission is to inspire people to discover why design matters. The CAC collaborates with community partners (such as chambers of commerce, neighborhood organizations, arts and culture organizations and historical societies) each year to present Open House Chicago. OHC is also made possible through generous support from festival sponsors, donors and government agencies.

What kinds of sites are included in Open House Chicago and where are they located?

OHC is a citywide event, with sites and events distributed throughout multiple neighborhoods, areas and select Chicago suburbs. OHC sites and neighborhoods represent the cultural diversity and dynamic history of Chicago, as well as the unique character of each community.

How are sites selected for inclusion in Open House Chicago?

CAC staff members curate OHC sites in accordance with multiple criteria. Site consideration and selection may also be informed by each year’s festival focus and themes.

Divvy, Chicago's bike-sharing system, and CTA buses and trains are great modes of transit during OHC. Many neighborhoods are easily accessible by CTA.

What are OHC programs and how can I attend?
