Your questions

Questions we are asked.

Have a question about your property or transaction? Talk to our team.

How much does a Phase I ESA cost in Illinois?

$1,495 flat for standard-scope commercial properties anywhere in Illinois, delivered in 5 business days from authorization and confirmed site access.

Who performs the site visit in Illinois?

A qualified field professional local to the property, booked when you authorize and supervised by our Environmental Professional. Your confirmed delivery date already accounts for the site visit.

Is the report accepted by lenders and the SBA?

Phase I reports are written to ASTM E1527-21 and EPA’s All Appropriate Inquiries rule, signed by an Environmental Professional who meets 40 CFR 312.10, and delivered with the Appendix 5 reliance letter that SOP 50 10 8.1 requires on SBA loans. If noncompliance causes a lender or SBA rejection, we correct the report at no charge or, if we cannot, refund its fee; our engagement terms list the exclusions.
