Adjusts method of determining regional need for affordable housing; permits timeline extension for municipalities to determine and plan for adjusted fair share obligations based on revisions to regional need.

S 2458 adjusts how New Jersey municipalities calculate their regional affordable housing needs under the Fair Housing Act. It changes the method to base "prospective need" on certified new residential housing units created (excluding replacements), rather than previous approaches. This bill directly affects all New Jersey municipalities required to meet affordable housing obligations, giving them extended timelines to revise their plans based on the new calculation method. The change aims to align housing requirements with realistic development patterns, as highlighted in recent court decisions. The bill amends 1985 and 2024 housing laws to implement this data-driven approach.
