Shawnee Square is a 28,320-square-foot, grocery- and service-anchored retail strip center located at 601 N. Commercial Street in Harrisburg, Illinois — the city's dominant retail corridor. The center is strategically positioned between two high-volume shadow anchors, Kroger and Tractor Supply, and sits within an established retail node that also includes ALDI, Rural King, Arby's and Super 8, driving consistent daily consumer traffic to the site. The property was extensively renovated in 2024–25 with a modern updated façade. The shopping center building comprises nine (9) suites ranging from 1,280 to 7,200 square feet and is currently 69% occupied (seven of nine suites leased), anchored by a strong, diversified tenant mix including Factory Connection, Keith's Place Restaurant, Planet Hibachi (opening soon), Luxury Nails, and Mr. Cloud & Vapes. Two suites are now available for lease: Suite 9 (1,600 SF) and Suite 10 (7,200 SF), which can be leased individually or combined for up to 8,800 contiguous square feet. Asking rent is $12–$14 PSF on a triple-net (NNN) basis with estimated NNN charges of approximately $1.90 PSF. A tenant improvement allowance and pylon signage are available to qualified tenants. The site offers a functional shared surface parking field, frontage on N. Commercial Street, and access to all public utilities. The trade area serving the center exceeds 33,000 residents, with an average household income of $70,510 within three miles. Shawnee Square represents an excellent opportunity for retail, service, restaurant, or medical users seeking visibility and co-tenancy within Harrisburg's primary shopping destination.
