The No Homeless Detention Centers Act prohibits organizations that receive federal housing funds from the Department of Housing and Urban Development from forcing homeless people to live in designated shelters or facilities, or from punishing them for activities necessary to survive on public property such as sleeping, eating, or sitting. The bill also bars these HUD-funded entities from requiring homeless residents to work in exchange for shelter or from cooperating with law enforcement actions that punish homeless individuals for basic life activities in public spaces. The legislation defines life-sustaining activities to include sleeping, resting, eating, drinking, and protecting oneself from the elements, and it applies to all recipients of HUD federal funds, including state and local governments. The bill responds to recent state legislation and executive orders that have criminalized homelessness and proposed forced placement in camps or facilities, which the legislation characterizes as similar to detention centers. No specific funding amount or implementation timeline is specified in the bill text.
