(g)
Unnecessary cost generating features. In order to eliminate unnecessary cost generating features for affordable housing developments, as required by the Fair Housing Act, N.J.S.A. 52:27D-314b, any development in the AH zoning district shall be entitled to the rights and relief provided in the rules of the New Jersey Council on Affordable Housing for inclusionary development and as set forth in N.J.A.C. 5:93-10.1(b).
