Commercial Properties Can Be Loaded with Hidden Liabilities. Phase I ESAs Protect You
Purchasing commercial property is a major investment that also involves land-use regulations.
While standard commercial inspections cover issues related to the property’s condition, they don’t address past and present land issues, which can be a massive liability for industrial and construction projects.
Environmental contamination isn’t always visible to the eye, but can have long-term financial consequences, including:
- Contamination from former industrial or commercial use
- Unknown underground storage tanks (USTs)
- Chemical spills, fuel leaks, or hazardous waste
- Nearby properties with environmental violations
- Soil or groundwater concerns
- Gaps in historical property records
Missing these risks can derail a sale, block financing, or leave buyers with costly environmental cleanup responsibilities.


Get Peace of Mind with a Phase I ESA
A Phase I ESA identifies environmental concerns early, before they become your responsibility or liability. Our Certified Master Inspectors perform a comprehensive assessment that includes:
- Historical record review
- Aerial image and map comparison
- Federal, state & local database searches
- Property walkthrough
- Interviews with current/past owners
- Clear findings with professional recommendations
This process ensures compliance with ASTM E1527-21 and the EPA All Appropriate Inquiry (AAI) standards, providing investors, lenders, and commercial buyers with the documentation they need to move forward confidently.
