History

For 75 years, three generations of our family have specialized in the housing and construction business. It started when the family patriarch, Lyon Hartman, owned and operated two rooming houses near the University of Illinois in 1937. Our family business grew when Lyon and his brothers went into construction in 1946 operating under the name “Hartman Construction Company”.

The name “JSM Apartments” was coined in 1974 after sons Jeff, Steve, and Mike Hartman inherited rental property located at 505 E. Clark in Champaign, Illinois. Over 40 years later, JSM has grown to form JSM Apartments, JSM Commercial, and JSM Development Services based in Champaign-Urbana, Illinois.
