Step inside hundreds of iconic buildings and homes during the Chicago Architecture Center’s free, citywide festival this weekend.

Open House Chicago—one of the world’s largest architecture and urban exploration festivals—returns this weekend thanks to the Chicago Architecture Center. With 210 locations scattered across 25 Chicago neighborhoods, this year’s installment is the festival’s biggest yet. Along with peeping behind the doors of some of the city’s most architecturally and culturally significant buildings, Chicagoans can also enter a photo competition, play architectural bingo via the Chicago Reader’s festival guide and enjoy free private tours of residential spaces normally closed to the public. Here’s everything you need to know about Open House Chicago 2025.

Yes, Open House Chicago is a free festival open to all.
Open House Chicago takes place on Saturday, October 18, and Sunday, October 19, 2025. Most sites will be open 10am to 5pm. If your heart’s set on visiting a particular building, double-check its hours via Open House Chicago’s site directory.
Open House Chicago spans 25 Chicago neighborhoods, including Avondale (one of the coolest neighborhoods in the world, according to Time Out), Englewood, Hyde Park, Logan Square, Pilsen and Ukrainian Village.
If you’re not game to manually sift through Open House Chicago’s hundreds of sites, the festival’s website offers several pre-built itineraries. The itineraries are organized around themes like “Urban Agriculture” and “Highlights of the Black Metropolis.” There are even agendas built around whichever “L” train you’re using to explore the city.
Open House Chicago is also stationing four neighborhood headquarters throughout the city—Ravenswood, North Lawndale, Bridgeport and downtown—where attendees can plan their routes, utilize free Wi-Fi and chat with Chicago Architecture Center representatives.
Whether you’re a skilled shutterbug or a hobbyist armed with an iPhone, this is your time to shine. Open House Chicago attendees can submit photos taken at any of the festival’s sites in one of five categories: interior, exterior, detail, black & white and people & buildings. Selected entrants will have their photography printed and displayed at the Chicago Architecture Center’s November 2025 exhibition “Framed Views: OHC Photography.” Learn more about the competition here.
Over 30 new sites have been added to Open House Chicago’s roster this year. Highlights include the just-opened Aspire Center for Workforce Innovation in Austin, a 7-Eleven-turned-chamber music venue in Uptown and the late Steve Albini’s legendary Avondale recording studio Electrical Audio.
