Markets that fund housing are the most critical piece of the resource puzzle and important arbiters of housing stock and availability. While decisions on individual loan applications obviously influence what is built or rehabilitated, many factors underlie those decisions, including federal funding and regulatory determinations, along with the risk perceptions of public and private funders. National research shows that federal housing rules favor homeowners over renters and single-family homes over multifamily homes, creating policies that prevent markets from responding to changing demand.{{Chicago Metropolitan Agency for Planning, “Housing Choice,” 2017,}} For example, the U.S. Department of Housing and Urban Development, Federal Housing Administration, and Fannie Mae and Freddie Mac programs limit the amount of non-residential space allowed within developments as a condition for receiving federal financing or loan guarantees, thereby making it difficult to finance construction and renovation of low-rise, mixed-use buildings. Many private lenders use risk assessment criteria based on the federal regulations, meaning that mixed-use projects not seeking federal financing or loan guarantees can still be affected. While many different laws and regulations influence the market, it is not yet clear which are most influential in our region. CMAP will determine which aspects of federal regulations are the most substantial barriers to the pursuit of housing choice and promotion of compact, mixed-use housing in metropolitan Chicago and outline local, regional, state, and federal strategies to address these barriers.
