Environmental Site Assessment (Environmental Due Diligence)

The Environmental Site Assessment (ESA) is a process of evaluating the environmental liability of a real estate asset. Environmental liabilities are one of the most common reasons for incurring unexpected expenses in connection with the purchase of a commercial property. These unforeseen liabilities can even result in business owners not being able to use a commercial property for its intended purpose, preventing them from getting back their investments. Environmental Due Diligence (EDD), a process of assessing the environmental conditions of a property in connection with a property merger or acquisition (MA) , is important for investors to be aware of the potential environmental liabilities.
