Section 8 housing is a federally funded program aimed to assist low-income families in America pay for rent. There are two different branches of the Section 8 program: the Housing Choice Voucher program (called "tenant-based" assistance), which allows you to choose the housing location; and "project-based" assistance, which requires you to live at a specific property.
The United States Department of Housing and Urban Development (commonly referred to as HUD) provides funding for Section 8, along with several other affordable housing programs such as Public Housing. Thousands of housing authorities located around the country receive the funding from HUD, and administer Section 8 vouchers (among other programs) within its local jurisdiction.
Qualified families or individuals accepted into the Housing Choice Voucher program receive a voucher that pays a portion of their monthly rent. The tenant is responsible for paying 30 percent of their monthly adjusted income for rent. This amount can be adjusted through deductions including child care expenses and medical expenses, among others. The voucher covers the difference.
