Central Jersey: Middlesex, Mercer, Monmouth — moderately high costs, mix of union and open shop.
South Jersey (Philadelphia orbit): Camden, Burlington, Gloucester — lower than North Jersey but still above national averages, influenced by Philadelphia market.
Shore counties: Ocean, Atlantic, Cape May — seasonal demand, hurricane-resilient construction requirements add cost.

What drives costs in New Jersey

Union labor: New Jersey has one of the strongest union construction markets in the country. Public projects and many large private projects require union labor, which carries higher base wages and benefit packages.

Prevailing wages: New Jersey's Prevailing Wage Act applies to all public construction work. Rates are published by the NJ Department of Labor and can exceed market rates significantly.

Regulatory burden: Building codes, environmental regulations (NJDEP wetlands, flood zones), and permitting processes add cost and timeline.

Land and demolition: New Jersey is the most densely populated state. Most construction involves demolition of existing structures, contamination remediation, or brownfield development — all of which add cost.

Transportation: Heavy traffic increases delivery costs and limits work hours. Many municipalities restrict construction deliveries to specific hours.
