In just 10 months, we have gone from breaking ground here in North Lawndale to delivering new homes that will give Chicagoans the opportunity to put down roots and build wealth in our city. And this is only the beginning: we will continue investing boldly to build the homes our communities deserve. @ChicagoDPD

Thank you to the ASHRAE IL Chapter for having us to talk mechanical code updates in Phase 3 of the Chicago’s Construction Code Modernization Initiative. Good code gets better when the industry professionals who use it everyday are in the room. Grateful for your partnership!
