Franklin County, Ohio, has grown in population and economic prosperity over the past two decades and is one of the most economically vibrant areas of the country. Yet many of its residents are not benefitting from this economic success. Affordable housing  has become an increasingly serious concern as the housing market tightens with population growth, rents rise to take advantage of increasing demand, and incomes are not keeping pace with housing costs. The Affordable Housing Alliance of Central Ohio (AHACO) was formed in 2015 by a group of non-profit organizations that, among them, are involved in the full spectrum of affordable housing projects and programs. Working together with local and state government, developers, community leaders, and residents, the goal of AHACO is to increase the supply of new and existing affordable rental and homeownership opportunities in Franklin County to improve the quality of life for everyone. In 2015, AHACO released city and county policy platforms that described the need for affordable housing, identified an estimated shortage of 54,000 affordable housing units in Franklin County, and outlined strategies to cut this shortage in half over ten years. As the Alliance spoke to community leaders about the platform, it became clear that research was needed to refine and support the policy agenda. Of particular interest was a scan of what other communities across the country were doing to generate  local resources for affordable housing. The Greater Ohio Policy Center was selected by AHACO to undertake this research.
