Housing scholars have demonstrated that intimate partner violence (IPV) is a key driver of housing instability. Contributing to existing housing literature that foregrounds the importance of material and psychological housing instability, our empirical research focuses on a novel programme providing supportive housing for women, the majority of whom are allocated housing to protect them from IPV. Our data includes in-depth interviews with the supportive housing tenants and practitioners, as well as administrative data. Our findings illuminate the close interrelation between material and psychological housing instability, and demonstrate how problems inherent in the private rental market interact with issues caused by perpetrators’ ongoing use of violence in ways that make it impossible for women to achieve either form of stability. The implication for housing scholars is to understand that although affordable housing is a protective measure, supportive housing models that rely on the private rental market, face profound limitations in achieving material and psychological housing stability for women who experience IPV.
