LocationOne Information System (LOIS)
The Illinois Department of Commerce & Economic Opportunity provides the LocationOne Information System (LOIS) for conducting searches for available commercial and industrial sites and building locations throughout Illinois. Maintained in partnership with communities across the state, LocationOne is designed to address the specific site selection data requirements of businesses and their consultants.
To conduct a statewide or multi-regional search, please select from the following:
- To conduct a search within a specific economic development region, click a region on the map
- To learn about Communities where properties are located, please view their Community Profile
For assistance, please contact David Pierson 312.814.1346 or firstname.lastname@example.org if you cannot find your ideal site or building.
Note: If you are responsible for a community’s data and would like to add your local information to LOIS, please contact email@example.com for LOIS training information and a user ID. No representatives may be given rights to enter/edit their data without proper training or Department of Commerce approval.
