SBA loan basics
Short answer
Yes, if your SBA 7(a) loan involves real estate, an environmental investigation is almost always required to check for potential hazards.
When real estate is collateral for an SBA 7(a) loan, lenders must conduct environmental due diligence to identify and evaluate potential environmental contamination or hazards. This typically starts with an Environmental Questionnaire (Form 1081) and may escalate to a Phase I Environmental Site Assessment (ESA) or even a Phase II if potential issues are identified. The SBA aims to protect itself and lenders from liability for environmental cleanup.
If you're buying a building that was formerly a gas station, a full Phase I ESA would likely be required, possibly followed by a Phase II investigation, to assess for potential underground storage tank leaks and soil contamination.
