SBA Commercial Construction Loans

Ground-up construction of owner-occupied commercial property is fully SBA-eligible through 504 or 7(a). The structure differs from acquisition deals — interim construction financing rolls into the SBA permanent loan at completion.

Construction-to-Permanent SBA Financing

The SBA permits ground-up construction under both 504 and 7(a). The structure: a bank provides an interim construction loan during the build period, and at certificate of occupancy the construction loan rolls into the permanent SBA structure. For 504 deals, the bank takes the first mortgage and the CDC funds the SBA debenture once the property is occupied at the required threshold.

How SBA Construction Financing Works

Unlike conventional commercial construction loans (which typically require 25-35% equity and a hard takeout loan), SBA construction can be structured with as little as 10-15% borrower equity rolling into a 25-year fixed permanent. The trade-off is more complexity during the construction period: monthly draws against a budget, inspector sign-offs, and contingency holdbacks.

504 Construction Structure

The bank funds the entire project cost during construction as a "third-party loan with permanent take-out commitment." At certificate of occupancy and the borrower's business occupying 60%+ of the property, the CDC funds the SBA debenture and pays down the bank loan to 50% LTC. The borrower's 10-15% equity remains. The final structure is the standard 50/40/10 (or 50/35/15 for special-purpose).

7(a) Construction

For smaller construction projects (under $5M), the 7(a) can fund construction directly as a single loan. Draws are processed against a budget and project schedule. This single-loan structure is simpler but lacks the 504's 25-year fixed permanent.

Required Documentation

  • General contractor selected and contracted (or self-built operator with track record)
  • Detailed construction budget and timeline
  • Building plans approved by local jurisdiction
  • Builder's risk insurance during construction
  • Performance and payment bonds (typically required on larger deals)
  • Pro forma cash flow for the operating business after CO
What kills construction deals: insufficient hard contingency (lenders want 5-10% above project cost), GC inexperience, or unrealistic timeline. Add cost contingency upfront — mid-project change orders are painful with an SBA structure.
