1983] RESIDENTIAL SEGREGATION ORDINANCES 319 The realtor should not be instrumental in introducing into a neigh- borhood a character of property or occupancy, members of any race or nationality or any individual whose presence will clearly be detrimental to property values in the neighborhood.184 In the 1930's the new housing market was in Baltimore's annex where row houses were being built. These houses were sold to whites only. It would have been considered foolhardy to sell to blacks and whites in the same row.

Later, in the 1930's when the federal government became active in housing fields, it denied Federal Housing Administration support in neighbor- hoods with "inharmonious racial groups.188 In Baltimore in 1934 the 3,800 middle-class black families who could afford to own a house were those most immediately affected by the conspiracy of containment. If they already owned a home it was likely to be in the upper Druid Hill Avenue district, which still was "the best that Negroes could get in the city proper.189 Yet the neigh- borhood was in some respects unsatisfactory: it was noisy as a result of street cars, lacked recreational facilities, was removed from shopping facilities, and had areas of improper sanitation. Moreover, it was un- dergoing change. The neighborhood had been encroached upon by brothels and saloons.
