(d) 
Mandatory set aside for affordable housing. Subdivision and site plan approvals for developments within the district may only be approved if all of the dwelling units are age restricted affordable units, or units restricted to income eligible disabled adults, with the exception of a manager's dwelling unit, as defined in this chapter.
(e) 
Development requirements. For the purposes of determining compliance with this section, individual interior lot lines within the zone designation shall not be considered when determining setbacks. All measurements shall be taken from the boundary of the tract.

An alternative off-street parking standard pursuant to N.J.A.C. 5:21-4.14(c), which shall be 0.5 parking spaces per unit, will be used due to the demonstrated reduced need for off-street parking by residents of age-restricted low and moderate income housing.

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).
