Phase 1 ESA Checklist for First-Time Commercial Buyers
If this is your first commercial purchase, here's the practical order of operations: order early, confirm your lender's requirements, vet the provider's credentials, and track the 180-day report clock.
Buying your first commercial property means a lot of due diligence steps happening at once, and it's easy to treat the Phase 1 ESA as one more form to file rather than the thing it actually is: a real investigation with a real timeline that can affect your closing date. Here's the actual checklist, in order.
- Before you order: confirm your lender's requirements
A full Phase 1 ESA, or in some cases a Transaction Screen, and whether they need to be named directly on the report or have reliance language extended to them. Get this in writing early; it's a bad surprise to find out after ordering the wrong assessment type.
- Before you order: flag anything unusual
Ask your real estate attorney or broker whether the property's known history (past tenants, prior use, anything unusual you've heard) suggests you should flag anything specific for the environmental professional to look at closely.
- During: give the consultant prompt access
To the property, and to any records you already have (prior surveys, title reports, old permits). Delays here are one of the most common, and most avoidable, causes of a Phase 1 ESA running past its expected timeline.
- During: ask about preliminary findings
Get a rough estimate of when you'll see preliminary findings versus the full written report. Some firms flag a major concern early, even before the formal report is finished, which matters if it could affect your decision to proceed.
- After: read the conclusions section closely
Not just the summary. If a REC was identified, ask directly what the consultant recommends and why.
- After: track the 180-day clock
If the report is clean, note the inspection date and mark your calendar for the 180-day validity window in case your closing slips.
