This handbook describes a wide range of strategies that local governments, developers, and nonprofit organizations can use to create and retain affordable housing in their communities. Fifteen strategies for addressing affordable housing are discussed. The strategies are divided into three categories: housing production, housing retention, and asset building. The handbook adds to the body of literature on affordable housing strategies by considering the interplay of strategy implementation and housing-market context. The document serves as a companion piece for the report, In the Face of Gentrification: Case Studies of Local Efforts to Mitigate Displacement.
