<P> The Housing and Urban Development Act of 1970 introduced the federal Experimental Housing Allowance Program (EHAP) and the Community Development Corporation and authorized larger outlays for housing subsidy programs and rent supplements for moderate - income households . </P> <P> In the 1970s, when studies showed that the worst housing problem afflicting low - income people was no longer substandard housing, but the high percentage of income spent on housing, Congress passed the Housing and Community Development Act of 1974, further amending the U.S. Housing Act of 1937 to create the Section 8 Program . In the Section 8 Program, tenants pay about 30 percent of their income for rent, while the rest of the rent is paid with federal money . </P> <P> The Section 8 program initially had three subprograms--New Construction, Substantial Rehabilitation, and Existing Housing Certificate programs . The Moderate Rehabilitation Program was added in 1978, the Voucher Program in 1983, and the Project - based Certificate program in 1991 . The number of units a local housing authority can subsidize under its Section 8 programs is determined by Congressional funding . Since its inception, some Section 8 programs have been phased out and new ones created, although Congress has always renewed existing subsidies . </P> <P> The 2008 Consolidated Appropriations Act (Public Law 110 - 161) enacted December 26, 2007, allocated $75 million funding for the HUD - Veterans Affairs Supportive Housing (HUD - VASH) voucher program, authorized under section 8 (o) (19) of the United States Housing Act of 1937 . This new program combines HUD Housing Choice Voucher rental assistance for homeless veterans with case management and clinical service support which is provided by Veterans Affairs administration at its own medical centers and also in the community . </P>
