Something else to keep in mind is that the United States Department of Housing and Urban Development in 2015 adopted a rule entitled “Affirmatively Furthering Fair Housing.”  The enforcement of this rule, which is tied to certain grants and other programs operated by HUD (including CDBG grants), will require municipalities to analyze historical housing discrimination in the municipality, develop a plan to ameliorate the effects of such discrimination, and to provide continuing reporting to HUD concerning the municipality’s efforts to diversify its housing on such factors as race, color, religion, sex, disability, familial status or national origin.  Failure to comply with the AFFH rules may result in Federal oversight of local ordinances and rules and regulations – a prospect that may make State-mandated affordable housing rules seem tame by comparison.
