Open House Chicago celebrates the stories of Chicago neighborhoods and shows people how architecture and culture can transform a community. Over half a million people have participated in OHC since 2011—nearly all of them exploring new neighborhoods and finding new reasons to be proud of their city.

Help keep OHC free by donating to the Chicago Architecture Center today.

CAC is proud to work with our sponsors to provide Chicagoans and visitors the chance to explore Chicago’s neighborhoods.
