Environmental Concerns
When a Phase I assessment is appropriate, what triggers further study, and how findings affect financing.
AuthorKitsey Behrman
01
What It Means
A Phase I Environmental Site Assessment is a non-invasive review of a property's history, records, and current use to identify recognized environmental conditions — evidence that contamination may be present.
If a Phase I flags a concern, a Phase II involves sampling soil, groundwater, or building materials to determine whether contamination exists and to what extent.
02
Why It Matters
Environmental liability can attach to the owner regardless of who caused it. A completed Phase I is also what establishes the innocent landowner defense, and it must be done before you close to count.
Practically, most commercial lenders require it. Findings can delay closing, reduce loan proceeds, or end a transaction, so ordering it early protects your timeline.

Questions to Ask
- What has this site been used for historically, including prior structures?
- Are there current or former underground storage tanks on the property?
- Have any environmental reports been prepared before, and can I review them?
- What does my lender require, and how long will the report take?
- If a Phase II is recommended, who pays and how does that affect our timeline?
04
Common Mistakes
- Skipping a Phase I on properties with fuel, automotive, or agricultural history.
- Relying on a prior owner's report that is years out of date.
- Underestimating the calendar time an assessment adds to closing.
- Assuming a clean visual inspection rules out subsurface issues.
