5031 N. Illinois Street (Fairview Commons 5) is a 5,824 SF single-story, all-brick commercial building situated on a 1.1-acre lot along N. Illinois Street (Rt. 159) in Fairview Heights, Illinois, one of the Metro East’s busiest retail and office corridors carrying approximately 27,500 vehicles per day. Built in 2007, the building is fully sprinklered and offers excellent visibility and access directly off Rt. 159, minutes from St. Clair Square and the broader Fairview Heights retail trade area.

The property is currently occupied by a mix of established office and medical tenants, including Everside Health (occupational health services, ~3,200 SF, lease through approximately July 2029) and KRB Hospitality (~1,000 SF, lease through March 2027). A third suite of approximately 2,000 SF, previously occupied by Care Access Research (lease showed 1,410 SF), has a lease that expired November 30, 2024 with no renewal currently on file – ownership is confirming the current status, exact size, and availability of this space.

The property is offered at $20.00/SF on a triple net (NNN) basis, with the tenant responsible for gas, electric, CAM, insurance, and janitorial expenses. Ownership (ASKB LLC) is finalizing operating expense figures to confirm the NNN reconciliation.

This is a strong opportunity for a service, medical, or professional office user seeking a well-located, well-maintained building alongside stable, long-term neighboring tenants in a high-traffic corridor.
