Phase I Environmental Site Assessment
Florida
ASTM E1527-21 compliant Phase I ESAs for commercial real estate transactions across Southwest Florida.
Phase I Environmental Site Assessment Explained
A Phase I Environmental Site Assessment (ESA) is a due diligence investigation used to identify potential or existing environmental contamination on a commercial property. It is one of the most commonly required reports in commercial real estate transactions.
Following the ASTM E1527-21 standard, the Phase I ESA involves a review of historical records, regulatory databases, and a site reconnaissance to identify Recognized Environmental Conditions (RECs) — situations where hazardous substances may have impacted or could impact the property.
Completing a Phase I ESA is often required to establish an "innocent landowner" defense under CERCLA, protecting buyers from environmental liability associated with prior land use.
Florida presents its own set of environmental due diligence considerations. Decades of citrus and agricultural operations left pesticide residue on some parcels, older industrial and marine corridors around Tampa Bay, Fort Myers, and Port Charlotte carry legacy underground storage tank risk, and the state's high water table means contamination can migrate differently than it would in drier climates. A Phase I ESA satisfies the EPA's All Appropriate Inquiries (AAI) rule and gives buyers, lenders, and their counsel a documented basis for evaluating that risk before closing, rather than discovering it afterward.
Because ASTM last updated the standard in 2021 (E1527-21), older reports written to the previous E1527-13 standard may no longer satisfy lenders or meet AAI requirements — one more reason to confirm a report is current before relying on it in a transaction.

What's Included in a Phase I ESA
Records Review
Review of historical aerial photographs, fire insurance maps, city directories, and prior environmental reports.
Regulatory Database Search
Search of federal and state environmental databases for known contamination sites, underground storage tanks, and hazardous waste facilities.
Site Reconnaissance
Physical walk-through of the property to observe current conditions, potential contamination sources, and environmental concerns.
Interviews
Interviews with property owners, occupants, and local government officials to gather information about past and current land use.
Adjacent Property Review
Evaluation of surrounding properties for potential off-site contamination sources that could affect the subject property.
Written Report
Comprehensive ASTM E1527-21 compliant report with findings, RECs identified, and professional opinions and conclusions.
Understanding Recognized Environmental Conditions
The primary purpose of a Phase I ESA is to identify RECs — conditions indicating the presence or likely presence of hazardous substances on the property. There are three types:
REC (Recognized Environmental Condition)
Known or suspected release of hazardous substances that may have impacted the property requiring further investigation.
CREC (Controlled REC)
A past release that has been addressed with institutional or engineering controls remaining in place.
HREC (Historical REC)
A past release that has been fully remediated with no ongoing controls required.
De Minimis Condition
Minor environmental concerns that are not RECs and generally do not pose a material threat to the property.

Phase I ESA FAQs
How long does a Phase I ESA take?
A typical Phase I ESA takes 2–3 weeks from engagement to final report delivery, depending on the availability of records and scheduling of the site visit.
How much does a Phase I ESA cost in Florida?
Pricing varies based on property size, complexity, and location. Contact us for a custom quote for your specific property.
What happens if RECs are found?
If Recognized Environmental Conditions are identified, a Phase II Environmental Site Assessment may be recommended to further investigate through soil and groundwater sampling.
Is a Phase I ESA the same as a Phase II?
No. A Phase I ESA is a non-invasive records review and site reconnaissance. A Phase II involves physical sampling of soil and groundwater to confirm or rule out contamination identified in the Phase I.
How long is a Phase I ESA valid?
Under ASTM E1527-21, a Phase I ESA is valid for 180 days. After that period, an update may be required to meet lender requirements.
Is a Phase I ESA different from a Property Condition Assessment (PCA)?
Yes. A Phase I ESA looks at environmental contamination risk. A PCA evaluates the physical condition of a building's structure and systems — roof, HVAC, electrical, plumbing, and life safety. Many lenders require both for a complete commercial due diligence package.
Does a Phase I ESA cover flood zones or wetlands?
Flood zone and wetland designations are typically addressed separately from a Phase I ESA, though the report will note regulatory database findings related to nearby contamination sources. Flood zone status is usually confirmed through FEMA maps as part of the broader due diligence process.
Do all commercial lenders require a Phase I ESA?
Most institutional, SBA, and CMBS lenders require one before closing on commercial property, since it protects both the lender and buyer from unknowingly inheriting environmental liability. Some smaller private loans may not require it, but it is still recommended for buyer protection.
