SBA SOP 50 10 is the Small Business Administration’s Standard Operating Procedure for its 7(a) and 504 loan programs — including the environmental due diligence rules that decide when a Record Search with Risk Assessment (RSRA) is enough and when a full Phase 1 ESA is required. The newest edition is SOP 50 10 8.1, effective October 1, 2026, for loans that receive an SBA loan number on or after that date. Applications submitted through September 30, 2026 still follow SOP 50 10 8.

The link goes straight to the SBA’s own document page, so you always get the authoritative copy. Note that SBA publishes SOP 50 10 8.1 as a Word file (“SOP 50 10 8.1 effective 10.1.2026.docx”, about 1 MB), not a PDF — open it in Word or Google Docs, or export it to PDF yourself. The same page keeps every prior version (8, 7.1, 7, 6, 5(K)) if you need to check which edition an older loan was underwritten under. You might also want the SBA Environmental Flow Chart, which walks you through the environmental eligibility logic at a glance.
What Changed in SBA SOP 50 10 8.1?
SBA announced version 8.1 in Information Notice 5000-880695 on August 14, 2026. It folds every policy and procedural notice issued since June 2025 into one document and rewrites the rules for buying a business with an SBA loan. Here is what changed:
- Change-of-ownership loans are now sorted into four types — Initial Acquisition, Business Expansion, Owner Buyout, and ESOP/Cooperative — each with its own equity and underwriting rules, all collected in a new Appendix 15.
- Quality of Earnings (QoE) reports are required on larger deals. For Initial Acquisition and Business Expansion transactions with a purchase price of $3 million or more, the lender must obtain an independent QoE report (including a “Cash Proof” that reconciles bank statements to tax returns) in addition to the business valuation, and must use the QoE earnings in its debt service coverage calculation.
- Debt service coverage is measured on history, not projections. Initial Acquisitions, Owner Buyouts, and ESOP/Co-op deals must show a 1.25:1 debt service coverage ratio on the last fiscal year or a two-year average; Business Expansions need 1.15:1.
- Minimum equity injection is 10% for every change-of-ownership type, based on total project cost. For Initial Acquisitions it cannot be reduced or waived; for Business Expansions and Owner Buyouts the lender may reduce it if the borrower has enough liquidity and working capital.
- Same-institution debt refinancing gets new flexibility under delegated authority, with the requirements moved to a new Appendix 14.
- Seven new appendices (14–20) consolidate refinancing, changes of ownership, guaranty amounts, loan maturities, interest rates, collateral, and application-submission rules that were previously scattered through the chapters.
- Prior notices are baked in: the citizenship and residency rules from Policy Notice 5000-876441, International Trade Loan updates, coordination of 7(a) and 504 maximums, the Prior Loss Rule, MARC loans, the sunset of the SBSS score for 7(a) Small Loans, and SOFR/Treasury alternate base rates.
- Environmental due diligence: unchanged. We compared the Environmental Policies and Procedures chapter of SOP 50 10 8 and 8.1 line by line. The only edits are wording — every reference to “E-Tran” now reads “the SBA Loan System.” The NAICS screen against Appendix 6, the $250,000 loan threshold, the SBA environmental questionnaire, the Records Search with Risk Assessment (RSRA), the Transaction Screen, the Phase 1 ESA requirement for environmentally sensitive industries, the Appendix 5 Reliance Letter, and the one-year report age limit all carry forward exactly as written.
We track every SOP revision so your report is always written to the version your lender is actually using. For the deeper question of whether the RSRA is replacing the Phase 1 ESA, see our RSRA vs. Phase 1 ESA guide.
