CBC provides environmental due diligence evaluations for clients nationwide. Whether it is a Phase I environmental assessment for multifamily or a redevelopment project with a land use designation change, Commercial Building Consultants is here to serve you. CBC conducts on-site environmental due diligence to meet the guidelines outlined by ASTM for Phase I Environmental Site Assessments (ESA) for multifamily and commercial real estate parcels.


An ESA identifies Recognized Environmental Conditions (RECs).  According to the American Society for Testing and Materials (ASTM), Phase I ESAs should comply with the current ASTM E1527-13 “Standard Practice for Environmental Site Assessments.”  Commercial Building Consultants provide this environmental service in evaluating your project for “Recognized Environmental Conditions.”  The ASTM standard, which can be accessed online, defines Recognized Environmental Conditions, commonly referred to as RECs.


RECs require evidence of  “the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: (1) due to any release to the environment; (2) under conditions indicative of a release to the environment; or (3) under conditions that pose a material threat of a future release to the environment.  De minimis conditions are not recognized environmental conditions.”  Commercial Building Consultants conduct a thorough Phase I Environmental Site Assessment and provide a detailed professional opinion, based upon the ASTM’s requirements for environmental professionals.


Many commercial property owners wonder what the difference is between a Recognized Environmental Condition (REC) and a “de minimis condition.” provides the definition as well as the applicable standard practices for Environmental Site Assessments (ESA) and Property Condition Assessments (PCA).  Commercial Building Consultants often perform a PCA, along with a Phase I, ESA.

What is a de minimis condition? “De minimis conditions generally do not present a threat to human health or the environment and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies.” (Refer to: ASTM E1527-13, Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process, ASTM International, West Conshohocken, PA, 2013,, DOI: 10.1520/E1527)
