Frequently Asked Questions

What is a Phase 1 ESA?

A Phase I Environmental Site Assessment evaluates a property's historical use and current conditions to identify potential contamination. It's typically required for real estate transactions and financing.

What factors influence cost?

Property size, location, historical complexity, and the consultant's experience. Urban areas and industrial sites cost more.

How long does it take?

A standard Phase 1 ESA takes 2–4 weeks, depending on property history and site access.

Is a Phase 1 ESA required for all properties?

Not always, but it's highly recommended for commercial transactions and often required by lenders.

What if contamination is found?

If Recognized Environmental Conditions (RECs) are identified, a Phase II ESA (soil/water sampling) may be recommended, which adds additional costs.
