Open House Chicago

About This Event

Open House Chicago is exactly what it sounds like: two free days every October when 170-plus buildings across 20-plus neighborhoods — bank lobbies, theaters, private clubs, a working firehouse, architecturally significant homes — open their doors to anyone who shows up, no ticket and no docent fee required.

It's a genuinely global idea, not a Chicago invention. Open House London started the whole concept in 1992, and by the time Chicago joined in 2011, more than a dozen other cities already ran their own version; today over 50 cities hold an Open House festival, together reaching more than a million people a year. Chicago's edition is organized by the Chicago Architecture Center, which itself dates to 1966, when it started as the Chicago Architecture Foundation with one specific mission: saving the historic Glessner House from demolition.

Worth knowing before you go: there's no single ticket or wristband for the weekend — each site sets its own hours and access rules, some cap entry with timed passes that fill up online beforehand, and the most popular stops (bank lobbies, private clubs) draw real lines. Pick three or four sites you actually want to see and build a route, rather than trying to wing it citywide in one weekend.
