New Jersey is among the most expensive states to live in and there are numerous existing barriers to constructing new affordable housing. Excessive regulations have been found to drive up the already high housing costs by 35 percent, which pushes out those with lower incomes. In the past, the financial viability of inclusionary zoning sites was not considered when developing new affording housing. The actual production of affordable housing in New Jersey has been inhibited by high mandatory set asides and unrealistic site selections. Additional barriers to building new affordable housing in New Jersey include mandatory parking space requirements and unregionalized school districts, which causes the state to have the most school districts per county resulting in duplicative buildings and equipment driving up property taxes and housing costs.
