How much does a Phase I ESA cost in NYC?

Most NYC Phase I ESAs cost $2,640–$5,625. Smaller outer-borough commercial parcels can be lower; complex Manhattan multi-parcel sites can be higher.

What is NYC OER and does it affect cost?

NYC OER administers the NYC Brownfield Cleanup Program and (E)-designations. Sites with E-designations require additional review that can increase Phase I scope and cost.

Yes. Envicon Group offers 1-week Phase I ESA turnaround in all five NYC boroughs for qualifying sites.

Does the cost include vapor intrusion screening?

A standard Phase I includes a vapor encroachment screen per ASTM E2600. Actual sub-slab or indoor-air sampling is a Phase II scope and priced separately.

Do you work with NYC lenders and attorneys?

Yes. We work daily with NYC commercial lenders, real-estate attorneys, and brokers on closings.

Is a Phase I ESA required for NYC commercial transactions?

Lenders almost always require one. Buyers also need it to claim CERCLA innocent-landowner protection.

Phase I ESAs in New York City (Manhattan, Brooklyn, Queens, Bronx, Staten Island) generally cost more than suburban work because of denser historical records, NYC OER (Office of Environmental Remediation) coordination, tighter site logistics, and a higher likelihood of vapor intrusion or fill-soil concerns. Most commercial transactions in NYC fall in the $2,640–$5,625 range.
