About EcoAssessCosts
Last updated: May 2026
What we publish
EcoAssessCosts is an independent educational site focused on Phase 1 Environmental Site Assessment (ESA) pricing, timelines, and buyer due diligence in U.S. commercial real estate. We explain how quotes are built—not replace a licensed environmental professional on your deal.
How we research
Cost ranges and timelines reflect common U.S. market practice, ASTM E1527-aligned scopes, and patterns seen in lender-driven transactions. Figures are planning estimates; your consultant’s proposal controls scope, exclusions, and final fees.
Editorial standards
We avoid sensational claims, disclose when content is informational only, and update guides when standards or typical pricing shift. We do not sell placement to consultants and do not guarantee rankings or outcomes.
