The Boston Housing Authority is the largest landlord in Boston and the largest public housing authority in New England. As such, the BHA houses approximately 10 percent of the city's residents through its programs. In addition to providing conventional public housing, the Boston Housing Authority also provides affordable housing through the administration of several rental assistance programs. These programs include the federal Section 8 Voucher Program, as well as the state funded Massachusetts Rental Voucher Program that is overseen by the Department of Housing and Community Development. Through its rental assistance programs, the BHA also works with thousands of rental property owners throughout Boston, and collaborates to provide thousands of units of affordable housing.
