A federally-supported, tenant-based housing program administered by local housing authorities that provides assistance in the form of vouchers that enable income-eligible families to find and lease approved privately owned housing where the landlord has agreed to enter into a contract with the housing authority and/or finance agency. Tenant-based assistance provides rental subsidies that move with a household into any qualifying housing within a certain area. The housing can be (and often is) private housing that may not have been built with the intention of accepting solely low-income tenants, but if the quality and cost of the unit fall within a specified range, it may qualify. Eligible households pay approximately 30% to 40% of their adjusted gross income for rent and the housing authority subsidizes the balance.
