Single parents, workers on low incomes, families with children, pet owners, smokers and single adults are also among those who Wilson has barred from his properties.
A spokesperson for the campaign group Hope Not Hate group said: "You simply cannot treat people like this and deny them a place to live due to their skin colour.
"This is the unacceptable face of the housing crisis. There is something broken in the system when such a powerful figure can get away with such an appalling policy.
"Fergus Wilson's comments would seem laughably offensive, a throwback to the Alf Garnett era, if they weren't so serious in their implication.
Equality and Human Rights Commission chief executive Rebecca Hilsenrath said: "There are still deep inequalities in our society and these comments show why.
"As a country we all assume we have left the dark ages behind, but clearly there is more to be done.
"We will investigate and will be asking Mr Wilson to explain his actions. Unless we are satisfied that he will not break the law in the future we will take legal action."
Evolution lettings agency manager Roy Fever, who manages a number of Wilson's properties, said: "We don't condone this at all.
"We would never implement a policy like that. We put through anyone to the landlord and it is up to the landlord who they take on."
