To promote quality affordable housing to each household and has accessible and appropriate services that support individual and family success. Housing is an essential asset and economic engine for neighborhoods. A comprehensive Housing Planning Act provides the opportunity for Illinois to coordinate across public and private platforms to guide policy and funding towards meeting the housing needs of some of the most vulnerable Illinoisans. Creating the ACHP is a collaborative effort between the Housing Task Force and the participating State Agencies. An additional function of the plan is to catalog funding activity administered by the State for affordable housing construction, rehabilitation, preservation, subsidized home mortgages, operating or rental housing subsidies, and support services. The major  ACHP  responsibility is to find out new developments in the housing world via this Technical Plan.

In the first Comprehensive Housing Plan in 2003, the Housing Task Force developed Housing Principles to generally reflect important overarching themes in affordable housing: production (Creation and Preservation); services (Affordability and Choice); and promotion of long-term goals (Leadership). These principals are still used as an organizing mechanism that helps to focus different planning goals and tasks. To help clarify their intended purpose, each action item within the Technical Plan is identified in an annual focus area (determined annually by the Housing Task Force) and is categorized under a broader strategy and associated with one of the Housing Principles. Recommended annual efforts or program developments, and state agency activities related to the Technical Plan are presented in this Annual Comprehensive Housing Plan and progress is documented in Annual Progress Reports. The annual discussion topics are grouped into Focus Areas in order to provide context and background information not readily found within the annual and ongoing Technical Plan.
