FAQs
OHC is a free annual festival hosted by the CAC that offers behind-the-scenes access to buildings of architectural, cultural and historical significance during one weekend in October.
Since 2011, the CAC has produced each Open House Chicago (OHC) 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 OHC.
OHC is also made possible through generous support from festival sponsors, donors and government agencies.
CAC Members and OHC Volunteers receive a priority access pass which allows them to jump the line during Open House Chicago. Members can use their CAC digital membership card, which will automatically convert to a Priority Access Pass the week prior to OHC weekend. Volunteers will receive their pass via email before the event.
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.
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. Proposals for site inclusion are not generally solicited. Subscribe to our newsletter to get timely updates about the CAC's plans for the next OHC.
Neighborhood Headquarters are local stations staffed by CAC employees and volunteers during OHC weekend. Stop by for information, giveaways, and assistance during the festival. Locations will be announced closer to the event.
OHC is run by the Chicago Architecture Center, a nonprofit organization, and it is free to all participants. You can help keep OHC free by donating to the CAC here.
