When Do Lenders Require a Phase I ESA?

March 27, 20261 min read

A lot of people first hear about a Phase I ESA because a lender asks for it.

That is common in commercial real estate.

If financing is involved, the lender may want an environmental review before closing so they understand possible risk tied to the property.

Why lenders ask for it

Lenders are trying to protect collateral.

They want to know whether there are signs of environmental concern that could affect value, risk, or future liability questions.

When in the process it comes up

Usually, this comes up during due diligence or underwriting.

A lender may ask for the Phase I after the property goes under contract, before financing is finalized, or before internal credit approval is complete.

What lenders want to see

They usually want a report that is:

  • ASTM compliant

  • professionally prepared

  • clearly written

  • delivered on time

  • useful for underwriting review

Why NJ experience matters here

New Jersey properties are not one-size-fits-all.

Older sites, redevelopment areas, property history, and NJDEP context can all matter.

A common mistake

One common mistake is waiting until the lender asks for it at the last minute.

That can tighten the whole due diligence window and create pressure on the closing timeline.

Final thought

If a lender is involved in your commercial property deal, there is a good chance environmental due diligence will come up.

The sooner you confirm the requirement, the easier it is to keep the deal moving.
