This bill directs the Department of Housing and Urban Development to create a system allowing Native American tribes and tribal housing entities to voluntarily share unused housing vouchers with other tribes that need them. The Tribal HUD-VASH program provides rental assistance vouchers specifically to help Native American veterans find housing, but some tribes may not use all of their allocated vouchers while others face shortages. The HUD Secretary must establish this reallocation program within 180 days and ensure that tribes sharing unused vouchers face no penalty when future vouchers are allocated to them. Within the same timeframe, HUD must report to Congress on how many vouchers are unused across tribes, which tribes receive reallocated vouchers, and whether the overall program needs more funding. This legislation aims to make better use of existing resources to help more Native American veterans access housing assistance.
