Section 310 ILCS 67/20 - Determination of exempt local governments(a) Beginning October 1, 2004, the Illinois Housing Development Authority shall determine which local governments are exempt and not exempt from the operation of this Act based on an identification of the total number of year-round housing units in the most recent data from the U.S. Census Bureau for each local government within the State and by an inventory of owner-occupied and rental affordable housing units, as defined in this Act, for each local government from the U.S. Census Bureau and other relevant sources.(b) The Illinois Housing Development Authority shall make this determination by: (i) totaling the number of owner-occupied housing units in each local government that are affordable to households with a gross household income that is less than 80% of the median household income within the county or primary metropolitan statistical area;(ii) totaling the number of rental units in each local government that are affordable to households with a gross household income that is less than 60% of the median household income within the county or primary metropolitan statistical area;(iii) adding the number of owner-occupied and rental units for each local government from items (i) and (ii); and(iv) dividing the sum of (iii) above by the total number of year-round housing units in the local government as contained in the latest U.S. Census Bureau and multiplying the result by 100 to determine the percentage of affordable housing units within the jurisdiction of the local government.(c) Beginning on the effective date of this amendatory Act of the 98th General Assembly , the Illinois Housing Development Authority shall publish a list of exempt and non-exempt local governments and the data that it used to calculate its determination at least once every 5 years.
