Amends the Affordable Housing Planning and Appeal Act. Requires non-exempt local governments to provide residents with notice and the opportunity for comment at a public hearing prior to adopting an affordable housing plan. Requires a non-exempt local government to provide proof of its compliance with the notice and public hearing requirements when it submits a copy of its affordable housing plan to the Illinois Housing Development Authority. Expands the list of information that must be provided in the affordable housing plan to include, (i) an identification of "specific lands" (rather than "lands") within the jurisdiction that are most appropriate for the construction of affordable housing, (ii) proposed timelines to commence "specific actions and deadlines" (rather than "actions") to implement the components of the affordable housing plan, and (iii) incentives, including certain measures to address the need for affordable housing, that the local government may provide for the purpose of attracting affordable housing. In a provision permitting certain persons to appeal a local government's denial of a proposed affordable housing plan, expands the list to include a service provider that is under contract to provide services for potential residents of a proposed supportive housing project or community-integrated living arrangement that is included in the proposed affordable housing plan. Contains provisions concerning final actions or decisions by the governing body of the local government on the proposed affordable housing plans; appeal procedures and timelines; and other matters. Expands the Illinois Housing Development Authority's rulemaking authority to include the adoption of rules and regulations concerning the substance of affordable housing plans consistent with the changes made in the amendatory Act.
