SBA loan basics
Short answer
If a business or its real estate collateral has environmental concerns, the SBA 7(a) loan may require environmental due diligence, such as a Phase I Environmental Site Assessment (ESA).
The SBA requires lenders to assess environmental risk for loans involving real estate or businesses handling hazardous substances. Depending on the industry and property history, a Phase I ESA may be required. If the Phase I identifies potential contamination, a more in-depth Phase II ESA might be necessary to determine cleanup costs and liability. Significant unresolved environmental issues can render a project ineligible.
A business acquiring an auto repair shop located on a site where underground storage tanks were previously removed would likely require a Phase I ESA. If the Phase I reveals soil contamination, a Phase II ESA would be needed to quantify the cleanup costs, which could impact the deal's viability.
Insider move
Lenders must ensure all environmental due diligence is completed according to SBA guidelines. They worry about potential environmental liabilities impacting the collateral's value or the borrower's ability to repay, which could lead to a guaranty repair or denial.
