How many subsidized housing units are available in South Carolina?
Refreshed annually
In 2025, about 63,700 subsidized housing units were available in South Carolina. Approximately 12 percent of these were unoccupied and available to rent. Federally subsidized rental housing began with 1937’s US Housing Act, which created the United States Housing Authority and provided financial assistance to state and local governments for housing low-income people. Since then, the government has provided housing assistance to low-income renters through programs overseen by the US Department of Housing and Urban Development (HUD).

Tenant-based programs — known today as the Housing Choice Voucher program — are the most common form of housing assistance. Housing vouchers allow recipients to choose their own housing in the private market, provided it meets program requirements. Nationally, tenant-based programs account for approximately 55% of the subsidized housing stock. In South Carolina, tenant-based programs account for 48% of the subsidized housing stock.
Privately-owned, project-based programs provide subsidized housing in larger, multifamily housing developments through agreements between landlords and HUD, and account for 34% of all subsidized housing in South Carolina.
Tenant assistance was the most common type of housing program in 2025.
