The document summarizes a presentation given at the 2020 Fairfax County Housing Challenge on engaging non-traditional partners to address housing affordability challenges. It discusses how traditional approaches are often inadequate for today's rapidly changing environment. Non-traditional partners could help on both the supply side by overcoming constraints like available land and subsidies, and on the demand side by addressing issues that contribute to housing insecurity such as low incomes, rising non-housing costs, and lack of career opportunities. Examples of potential partners mentioned include hospitals, foundations, employers, and workforce development programs. The goal is to accelerate innovation through new thinking and partnerships to make greater progress expanding affordable housing options.
