Why Companies Choose Mundelein for Office Space
Mundelein is a central Lake County value market where office space runs along the Route 45, Route 60, and Route 176 corridors. Class B space asking ~$15/SF makes it one of the least expensive office markets in the North Suburbs — attractive for professional services firms, healthcare practices, and locally owned companies serving the Mundelein, Libertyville, and Grayslake population base. Two Metra Milwaukee District North stations serve the village, and IL-60 puts I-94 about ten minutes away, so the cost savings do not come at the price of isolation.
