Environmental issues represent one of the most serious and underappreciated risks in real estate acquisition. A property with significant environmental contamination can impose unlimited remediation liability on subsequent owners — potentially far exceeding the value of the real estate itself. Every serious real estate investor must understand the basics of environmental due diligence and never waive it in pursuit of speed or cost savings.
Phase I Environmental Site Assessment
The Phase I ESA is the standard starting point for environmental due diligence. Conducted by a licensed environmental professional, the Phase I reviews historical records, interviews current and past owners and tenants, examines aerial photographs and fire insurance maps, and physically inspects the site and surrounding properties for evidence of environmental contamination. The Phase I does not involve sampling or laboratory analysis — it identifies Recognized Environmental Conditions (RECs) that may require further investigation.
When to Proceed to Phase II
If a Phase I identifies RECs — evidence of underground storage tanks, historical industrial uses, proximity to known contaminated sites, or visible evidence of chemical use — a Phase II assessment is typically warranted. Phase II involves actual sampling: soil borings, groundwater monitoring, building material testing for asbestos and lead paint. Phase II results determine whether contamination is present, its extent, and the likely remediation cost.
Environmental Liability Protections
Federal law provides certain liability protections for purchasers who conduct appropriate due diligence before acquisition. The Bona Fide Prospective Purchaser defense protects buyers who are aware of contamination before closing but nonetheless acquire the property after completing proper due diligence, continuing care requirements, and not contributing to the contamination. RIYT works with environmental counsel on all acquisitions to ensure appropriate protection is established.
