Mainstream federal Housing Choice Vouchers are targeted to extremely low-income people with disabilities aged 18 to 62 and their families. Congress first funded Mainstream vouchers in the early 2000s in order to increase integrated housing options for younger people with disabilities. Since 2018, the Department of Housing and Urban Development (HUD) has awarded over $500 million in funding to public housing agencies (PHAs) to support 50,000 Mainstream vouchers. On behalf of HUD, TAC has provided PHAs with technical assistance regarding Mainstream vouchers and has helped states and localities use these vouchers to expand housing with services. From 2021 to 2024, TAC facilitated six communities of practice focused on increasing Mainstream Voucher utilization, developing PHA and service partnerships, and promoting community integration efforts. TAC has also conducted webinars and developed topic guides on the Mainstream program.
