For eight years, Open House Chicago (OHC) has offered free, behind-the-scenes access to the city’s hidden gems and architectural treasures.

Open House Chicago 2018 took place Saturday and Sunday, Oct. 13–14. In two days, an estimated 100,000 attendees made 366,000 visits to 279 sites in 29 Chicago neighborhoods and the adjacent suburbs of Evanston and Oak Park, making OHC one of the most-attended events of its kind in the world. 

This successful eighth year of OHC cemented the event’s status as the signature community initiative for the Chicago Architecture Center (CAC). How many people attended in 2018?

This is one of my favorite events in Chicago and we make plans to attend every year! Love discovering new neighborhoods and making a day date out of it!
