To promote and encourage open housing policies, the commissioner must establish affirmative marketing regulations for housing developers that receive more than $50,000 in state or local funds. The regulations must require the management or marketing agency for the housing development to adopt an information distribution or marketing plan for actively informing minorities and other protected groups of available housing opportunities. For purposes of this section, “protected groups” has the meaning given it in section 43A.02, subdivision 33. The commissioner may adopt rules to carry out the purposes of this section.
