Frequently Asked Questions
How accurate is this Phase 1 ESA cost estimate?
This calculator provides a typical price range based on data from 69 verified providers. Actual quotes may vary based on specific property characteristics, provider availability, and current market conditions. We recommend getting 2-3 quotes for comparison.
Why do gas stations and dry cleaners cost more?
Properties with higher environmental risk require more extensive historical research, additional database searches, and more detailed site inspections. Gas stations involve underground storage tank reviews, while dry cleaners require evaluation of solvent use and disposal practices.
What's included in a Phase 1 ESA?
A Phase 1 ESA includes historical records review (Sanborn maps, aerial photos, city directories), regulatory database searches (EPA, state agency records), site reconnaissance and visual inspection, interviews with current/past owners, and a written report with findings and recommendations. All work follows ASTM E1527-21 standards.
Do I need a Phase 1 ESA for my property?
A Phase 1 ESA is required by most commercial lenders (SBA, Fannie Mae, CMBS) and is recommended for any commercial property purchase. It establishes CERCLA liability protection ("innocent landowner defense") and identifies potential environmental issues before closing.
