Approval by the U.S. Department of Housing and Urban Development, or HUD, allows a landlord to offer the apartment for rent to low-income tenants through the Housing Choice Voucher Program, according to HUD. The program subsidizes rents, thereby guaranteeing payment of at least a portion of the tenant's rent.
The program participant typically pays up to 30 percent of his income toward rent, SFGate notes. The voucher covers the rest.
Landlords interested in getting their rental units approved contact their local Public Housing Authority, or PHA, offices after they've found suitable tenants, SFGate explains. After a landlord submits a Request for Tenancy Approval, the PHA inspects the property to make sure it meets habitability requirements..
