Are you interested in volunteering for Open House Chicago in 2026? The third weekend of October brings the annual Open House Chicago (OHC), a FREE event organized by the Chicago Architecture Center (CAC), offering behind-the-scenes access to some of the most amazing architecturally, culturally, and historically significant buildings in the city. If you enjoy learning about Chicago while engaging with and helping people, volunteering for Open House Chicago is an amazing opportunity. Volunteers, also known as Greeters, are the face of OHC and essential to the event’s success. All it takes is enthusiasm for the city and a willingness to chat with visitors.

Follow the Signs

  • Sign up: You can find information on how to register on the Chicago Architecture Center website. Because I volunteered before, I received a link to sign up in June.

  • Shift Selection: A Shift Selection Guide is generally released in late September, and you’ll choose your site and shift in early October. Be prepared to select your shift, as popular sites fill up fast.
  • Commit to a single shift, 3.5 – 5 hours, either on Saturday or Sunday.

  • A Priority Access Pass that lets you skip the line at some of the busier sites.

My Volunteer Experience: District Brew Yards

I volunteered for a morning shift at District Brew Yards from 10:45AM. to 2:45PM. Four volunteer openings were available for this site; two per shift. This was my fourth year supporting OHC, and I like to select a morning shift so I can visit other sites in the afternoon. I was happy to volunteer at District Brew Yards. I chatted with visitors and directed them to the tour, which started every 30 minutes.

Fun Facts about District Brew Yards

District Brew Yards is the nation’s first collective pour-your-own production brewery and beer hall under one roof. There are multiple independent local breweries in this space, allowing them to share knowledge and equipment, which might otherwise be too expensive. It operates as a self-serve, cashless bar with 40 taps, offering a unique experience for craft beer lovers. It also features incredible BBQ from Lillie’s Q (the smoked wings are a personal favorite.) I took the tour myself so I could answer questions about the facility. Plus, it’s one of my go-to spots before catching a Chicago Bulls game at the United Center, thanks to the convenient, free parking. My relief arrived at 1:45, and I strongly recommended she take the tour before starting her shift. I then took a 5-minute walk to the Roof Crop.

Entrance to The Roof Crop

Roof Crop

At this site, you will find an urban farm, Maxwell Trading (restaurant), a design studio and retail space (Third Season), and a foodservice innovation group (Flashpoint Innovation). The Roof Crop is a design-focused urban agriculture initiative that grows flowers, produce, and herbs on multiple rooftops across Chicago. It’s an eye-opening look at sustainability, ecology, and urban farming. In 2022, Hatch41 was an OHC site. The building on 41st and State Street also features a rooftop oasis.
Entrance to Chicago Magic Lounge

Chicago Magic Lounge

A bit further away in Andersonville, the Chicago Magic Lounge is an entertainment venue specializing in Chicago-style magic. Only 25 visitors were allowed at a time. Yes, I was the first person in line on Sunday morning. My experience began with entering through a hidden door—it’s a truly immersive theater experience. After a brief chat, we moved to the Harry Blackstone Cabaret Theatre. The group then toured the 654 Club. Only 44 seats are available. The final stop on the tour was the Performance Bar. By the way, a show ticket is not required for a cocktail and food at the bar. My crew is going to the Black Illusionist show in November.
