For SBA lenders
Short answer
A lender is generally not permitted to waive environmental due diligence requirements for real estate collateral, but the level of diligence (e.g., Environmental Questionnaire vs. Phase I ESA) varies based on risk.
The SBA requires lenders to perform appropriate environmental due diligence on all real estate collateral to protect against environmental liability and potential loan losses. While a Phase I ESA may not always be required (an Environmental Questionnaire can suffice for lower-risk properties), complete waiver of any environmental review is not allowed.
A lender processes a 7(a) loan for a new office building with no prior industrial use and a clean history. While a full Phase I ESA might not be needed, the lender must still complete an Environmental Questionnaire (SBA Form 1081) to fulfill basic environmental due diligence requirements.
Insider move
Lenders must always perform some level of environmental due diligence to identify potential risks. Failure to do so can expose the lender and SBA to significant environmental liabilities and jeopardize the guaranty.
