Why are building costs so high in New Jersey?
Labor wages are among the highest in the country and land is expensive across the metro region. Municipal permitting and energy code requirements add further cost above national averages.

Homes in flood zones must be elevated above flood levels and built with flood resistant materials. These requirements add significant foundation and structural cost near the shore.
