To every building owner and manager:

Don’t wait for a violation.

This Saturday, our teams joined 1,000+ volunteers from @RTMetroChicago for its 35th National Rebuilding Day, preparing 60+ homes across the city at no cost to homeowners.

Honored to join these engineers and industry leaders from across the country at the @ConcreteACI’s Spring Convention! As the only government rep. on the panel, we’re proud that our Facade Ordinance remains part of the national conversation. Safety doesn’t happen in silos. 🏙️ #ACI

The heat isn't done with us yet!
As temperatures climb above 80°F this weekend and next week, remember: You have a right to be cool!

The Chicago Cooling Ordinance requires qualifying buildings to provide air conditioning in common areas.

Stay informed, stay safe, stay cool.

17 communities across northern Illinois are now officially EV Ready!

Through our EV Readiness Program partnership with the Metropolitan Mayors Caucus, local municipalities are building the policies and infrastructure needed to support the growing demand for electric vehicles in our service territory. This program helps communities qualify for funding, increase EV adoption, and prepare for a cleaner future.
