Chicago is the Midwest’s undisputed data center capital. Home to major carrier hotels, financial exchange co-location facilities, and enterprise data centers, the Chicago metro area (particularly the suburban Elk Grove Village corridor) hosts one of the densest concentrations of data centers in the country.
Chicago’s Data Center Geography
Chicago’s data center market is concentrated in several distinct areas:
- Elk Grove Village / Itasca: The suburban powerhouse. Low-cost land, abundant fiber (CenturyLink, Zayo, AT&T routes), and municipal power from ComEd make this the preferred location for new builds. QTS, CyrusOne, and Flexential operate major campuses here.
- Downtown 350 Cermak / 427 S. LaSalle: Chicago’s famous carrier hotels. Equinix CH1/CH2 at 350 E. Cermak Road is one of the most interconnected data centers in North America. Low latency to financial exchanges makes these facilities critical for trading firms.
- Northbrook/Deerfield (north suburbs): Enterprise and healthcare data centers concentrated near the pharmaceutical and financial services corridor.
- Lisle/Naperville (west suburbs): Mix of enterprise and colocation facilities along the I-88 tech corridor.
Contractor Demand in Chicago
Chicago’s data center market creates strong demand for:

- Licensed electrical contractors: Illinois requires a Master Electrician license (city of Chicago also requires a city electrical license)
- Fire suppression: Illinois State Fire Marshal licensing for FM200, Inergen, and water mist suppression systems
Illinois Contractor Licensing
- Electrical: Illinois Department of Financial and Professional Regulation (IDFPR) — Electrical Contractor license. Note: City of Chicago requires a separate Chicago Electrical License.
- HVAC/Mechanical: IDFPR Plumbing license for refrigerant work; City of Chicago requires separate HVAC licensing
- Low voltage: Illinois Alarm Contractor license for integrated systems
