The Flexible Housing Pool (FHP) is a Supportive Housing Program initiated by Chicago and Cook County in 2019. Its primary objective is to provide housing for individuals who are high utilizers of the hospital emergency department, jail systems, and shelters and are also facing homelessness. The FHP utilizes an integrated housing, health, and social services design, consolidating various public and private investments into a single pool. This pool provides rental subsidies and services to eligible individuals.

FHP promotes an integrated housing and service delivery strategy aimed at increasing supportive housing for individuals impacted by homelessness with complex health needs, a history of justice involvement, and significant adversities. This innovative approach involves collaboration with support services providers, health care providers, housing finance agencies, housing developers, and philanthropy. It aims to create hundreds of housing units and facilitate connections between residents and the health system.
