The DC Department of Housing and Community Development, through its Rental Conversion and Sale Division (CASD), administers several laws and programs related to tenants in rental housing:
- Laws related to the conversion of property to cooperatives or condominiums, such as The Condominium Act, and The Rental Housing Conversion and Sale Act.
- The Tenant Opportunity to Purchase Act (TOPA), which is a unique law in the United States that gives tenant groups the opportunity to purchase their building when it is put up for sale.
- The District Opportunity to Purchase Act (DOPA), which gives the Mayor the right to purchase buildings with five or more rental units of which 25 percent are deemed as “affordable.”
- The Housing Assistance Payment Program (HAP) for tenants displaced because their apartment building is converted to a condominium or cooperative.
