Neighbors, Incorporated, was founded in 1958 to maintain racial integration in the Carter Barron East, Colonial Village, Manor Park, North Portal Estates, Shepherd Park, and Takoma Park neighborhoods. In the years following World War II, new suburbs were developed for white buyers. As whites moved out, African Americans began to move into formerly white DC neighborhoods. Unscrupulous real estate agents known as block busters tried to frighten remaining whites into selling their homes at low prices and then resold them at inflated prices to African Americans. In response a group of black and white homeowners in Manor Park formed the racially integrated Neighbors, Incorporated, to fight the block busters and bring about a genuinely integrated community.
In 1959 the group opened an office at this address. Neighbors, Inc. celebrated its 50th anniversary in 2008.
