1. New Jersey Administrative Code, Title 11, Chapter 5 (New Jersey Real Estate Commission), Section 11:5-6.4(h)1.ii: This regulation explicitly prohibits steering. It states, "No licensee shall... Engage in any activity which has the purpose or effect of steering any person away from or toward any housing accommodation or neighborhood because of any of the protected classes... 'Steering' shall mean the channeling of prospective buyers or renters to or away from a particular area on the basis of a protected class."
2. U.S. Department of Housing and Urban Development (HUD), "Fair Housing—It's Your Right": HUD defines steering as the act of "deterring a person from buying or renting a home because of their race, color, religion, sex, disability, familial status, or national origin... or otherwise making a home unavailable to them." The scenario in the question is a direct example of this prohibited act.
3. Ling, D. C., & Archer, W. R. (2018). Real Estate Principles: A Value Approach (6th ed.). McGraw-Hill Education. Chapter 10, "Legal and Ethical Environment," discusses fair housing laws, defining steering as the practice of directing minority homeseekers to minority neighborhoods, which is a violation of the Fair Housing Act of 1968.
