Phase 1 Environmental Site Assessment Cost in New Jersey
Typical Phase 1 ESA cost in New Jersey
$2,600–$5,850 per standard commercial parcel
Compiled from published 2026 industry cost guides (+30% vs. the $2,000-$4,500 national baseline). Full methodology on the cost data page.
New Jersey carries one of the largest cost premiums in the published guides, on par with Massachusetts. The state's dense industrial corridor along the I-95/New Jersey Turnpike belt, one of the most industrialized stretches of the country for over a century, means Phase 1 ESA consultants working in Newark, Jersey City, and the surrounding metro routinely review a heavier volume of historical and regulatory records than in less industrialized states.
What tends to drive cost up in New Jersey
New Jersey's industrial corridor has one of the highest concentrations of historically contaminated and regulated sites in the country, chemical manufacturing, refining, and rail-yard land uses are common recurring RECs, and the state runs its own site-remediation program (managed by the NJ Department of Environmental Protection) alongside the federal AAI process.

Frequently asked questions: New Jersey
Why is New Jersey one of the most expensive states for a Phase 1 ESA?
Published cost guides put New Jersey about 30% above the national baseline, reflecting the density of historically industrial and regulated sites along its I-95 corridor and strong consultant demand in the New York metro area.
Does New Jersey have its own environmental program on top of the federal one?
Yes, the state runs its own site-remediation program separate from the federal AAI rule. A Phase 1 ESA still has to meet the ASTM E1527-21 standard for CERCLA liability protection; state programs come into play separately if contamination is found or the property is subject to state disclosure rules.
Is Northern New Jersey different from the rest of the state?
Northern New Jersey's industrial corridor along the Turnpike and Newark Bay carries the state's heaviest concentration of historical industrial land use, which is why Phase 1 ESAs in this part of the state tend to involve more historical-record review than in South Jersey.
