This research investigates the nuances of local not-in-my-backyard (NIMBY) attitudes and actions, asking why some communities support publicly assisted affordable rental housing development, while others do not. Six case studies within New York State explore local acceptance and avoidance of affordable rental housing development through the low-income housing tax credit program. Findings inform future marketing, planning, and programming toencourage local participation in affordable rental housing development. More research is needed on the contextualized nature of NIMBY, how NIMBYattitudes and actions can be effectively reduced, and whether this increases the supply of affordable rental housing.
