Affordable Housing Planning and Appeal Act (AHPAA)
The Affordable Housing Planning and Appeal Act (AHPAA) was signed into law in 2003 to encourage local governments to incorporate affordable housing into their communities. IHDA was named the State-administering agency in the law and provides tools and updates to aid non-exempt local governments (NELGs), whose housing stock is calculated as having less than 10% affordability, with compliance. NELGs in Illinois are required to develop and then adopt an Affordable Housing Plan, which must be submitted to IHDA for review.
According to the statute, the exemption determination process must be completed by IHDA at least once every five years using data from the U.S. Census Bureau. IHDA completed its most recent affordability calculation and determination process in December 2023. The due date for NELGs determined under this cycle to submit plans to IHDA was June 14, 2025. This website contains information about the affordability of all communities across Illinois according to the AHPAA calculation, as well as the submitted plans and compliance status of NELGs.
