Except as otherwise regulated in this chapter, any development application proposing five or more new dwelling units shall be required to set aside 20% of said lots or units for affordable housing.

This requirement shall apply for all new multi-family residential developments of five or more units that become permissible through either a use variance, a density variance increasing the permissible density at the site, a rezoning permitting multi-family residential housing where not previously permitted, or new redevelopment plan.

This requirement does not give any developer the right to any such rezoning, variance or other relief, or establish any obligation the part of the Township of Rockaway to grant such rezoning, variance or other relief. A property shall not be permitted to be subdivided so as to avoid compliance with this requirement.
