The Upper Illinois River Valley Development Authority (UIRVDA) Enterprise Zone

The Upper Illinois River Valley Development Authority (UIRVDA) administers the UIRVDA Enterprise Zone (UVEZ). The Enterprise Zone Program is designed to provide state tax credits and exemptions as incentives to encourage businesses to make a new investment on property within the Zone. This stimulates business activity and creates new jobs.


A business must be located in the designated territory of the UVEZ in order to receive benefits. In May 2017, the UVEZ was initially designated in LaSalle and Kendall Counties. This territory can be expanded to any property in the Illinois Companies wishing to be in the UVEZ must apply to UIRVDA requesting the zone be expanded to include their property before starting and must have a project that creates substantial utility. The approval process generally takes 4-6 weeks dependent upon the complexity of the project. The UVEZ territory can be up to twelve square miles.
