This report outlines a series of non-statutory policy options that HUD could adopt to improve access to mainstream supportive services by residents of subsidized housing. These policy options respond to commonly reported challenges, including lack of onsite specialized capacity, limited and unreliable funding, and constraints on the use of common space to deliver services.In addition to policy recommendations, this report identifies four critical pathways to improving access: promoting co-location and coordination among housing and service providers, enabling housing providers to use existing funding more effectively, supporting access to service coordinators, and developing and initiating a forward-looking research agenda.
