Phase 1 Environmental Reports: What CRE Buyers Must Know

Confidentiality regarding Phase 1 Environmental Reports

Buying commercial real estate without a Phase 1 Environmental Report is like buying a used car without lifting the hood. Whether it’s a strip mall in Michigan or a logistics hub in Nevada, these reports are essential tools for assessing environmental risk—and they’re not always available for public consumption. In this post, we unpack what commercial real estate (CRE) buyers need to know about Phase 1 Environmental Site Assessments (ESAs), including confidentiality rules and state-level reporting requirements.

What Is a Phase 1 Environmental Report & Why CRE Buyers Can’t Ignore It

A Phase 1 Environmental Report (often called a Phase I ESA) is the industry-standard starting point for environmental due diligence. Rooted in ASTM Standard E1527-21, it involves a historical review, a site inspection, and interviews to identify recognized environmental conditions (RECs) that could impact the property’s value or future use.

For CRE buyers, these reports are crucial. They protect investments, flag contamination risks early, and are often required for financing, particularly when government-backed lenders like the SBA, HUD, or USDA are involved. A properly executed Phase I ESA can help shield buyers from liability under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as Superfund.

Nationwide, the process remains consistent, but nuances arise in how results are interpreted and reported—especially in states with stricter disclosure laws or more aggressive environmental enforcement.

Confidentiality + FOIA: When Reports Are Hidden or Discoverable

In most real estate transactions, Phase 1 Environmental Reports are strictly confidential. Unless you’re a party to the contract between the environmental consultant and the commissioning client, you’re unlikely to gain access to the findings. This confidentiality is foundational: consultants are obligated to keep data private—even for government projects.

But there’s a loophole: the Freedom of Information Act (FOIA) and its state-level cousins. If the report was commissioned by a government agency or funded with public money, you may be able to obtain it via an Open Records Request. Start by identifying the “FOIA Officer” in the agency, and send a concise email request. Many states make this process easy—no legal muscle required.

The golden rule: don’t contact the consultant directly. They’re contractually muzzled.

Reporting Contamination? State-Level Rules That CRE Buyers Must Understand

Let’s say the Phase 1 ESA reveals contamination—does anyone have to report it to regulators? That depends. The answer is delightfully murky and varies widely by state. Some states mandate immediate disclosure; others leave it to the consultant’s or buyer’s discretion.

Particularly tricky states include:

  • New York, New Jersey, Connecticut – Stringent reporting protocols

  • Minnesota, Massachusetts, Indiana – Unique consultant/client obligations

  • South Dakota, North Dakota, Mississippi – Vague but enforceable standards

Ownership matters, too. If the consultant is working for a buyer in a pending transaction, and the seller is unaware of contamination—who reports? It’s often left to attorneys to wrestle with this legal gray zone.

Bottom line: always know your state’s rules, and never assume silence is golden.

ASTM Standards & Lending Requirements for Nationwide Buyers

Across the U.S., the gold standard for Phase 1 ESA reporting is  E1527-21. These standards outline what constitutes a “compliant” report—vital for securing loans and protecting against future liability.

Nationwide, compliance with this ASTM standard is essential, especially when dealing with federal lending programs. The Small Business Administration (SBA), Department of Housing and Urban Development (HUD), and United States Department of Agriculture (USDA) all require ESA reports that meet or exceed these standards.

A3 Environmental Consultants ensures every report aligns with these stringent requirements, delivering peace of mind whether you’re purchasing a warehouse in California or refinancing a factory in Ohio.
