Hello, Orland Park. I'd like to take a few minutes to talk with you about something that deserves your attention and more importantly deserves real action. There is legislation currently moving through Springfield called the BUILD Act. At its core, this bill is designed to encourage residential development across Illinois by encouraging new housing construction.
The goal, as identified by the Governor and as the state sees it, is to address housing affordability and increased supply in communities throughout our region. Again, that is a worthy conversation to have. We all recognize the problem of affordability and availability. Housing matters. Growth matters. We recognize that.
This reference documents an analysis of sprinkler system prevalence in new residential construction permits issued in Chicago between January 1, 2020, and December 31, 2025. Permits are grouped by building type (single-family, small multi-family, large multi-family) and by whether their work_description references a sprinkler system.

| Increase Supply, and Lower Costs | |
| Working families are struggling to buy or rent a home because the United States, including Illinois, is facing a | |
| housing crisis. Illinois is short about 142,000 housing units and will need to build over 225,000 units in five | |
| years to keep up with growing demand. With few housing options to choose from, Illinoisans are spending | |
| more of their income on housing – oftentimes in inadequate spaces for their families. | |
| Developer demand to build is high, but red tape gets in the way. A patchwork of different local building | |
| restrictions makes it harder for developers to get permits to build, driving up the costs of building new | |
| housing. In the past five years alone, the number of home listings has dropped 64 percent and new construction | |
| permits have dipped to 13 percent. |
