“SBA loan for construction” means two different things, and our data can speak to both. It can mean financing the construction of a building, ground-up or a major rehab. Or it can mean financing a construction company’s own equipment, vehicles, and working capital. This page covers the first; if you run a construction business and need financing for the business itself, jump to the second section below, or see SBA loans for equipment for the vehicles-and-machinery side of that need.
Financing the construction itself
Two SBA paths actually fund ground-up construction, and in our data one of them is rare almost to the point of being a rounding error. The Builders CAPLine, a revolving 7(a) line built specifically to finance a small general contractor’s direct cost to build or rehabilitate property for resale, funded just 281 of 919,729 7(a) loans since FY2010, about 0.03%, as of the data’s March 2026 refresh. It is one of the smallest delivery methods in the entire 7(a) program, and one of the few SBA uses that permits financing non-owner-occupied investment property, since the whole point is building something to sell, not to occupy. See SBA CAPLines for how it compares to the other three CAPLine types.
Most SBA-financed new construction instead runs through the 504 program, financing a building the borrower will occupy, under a stricter version of 504’s standard occupancy rule:
- Existing building: occupy at least 51% of the rentable space.
- New construction: occupy at least 60% of the rentable space at completion, with up to 20% permanently leasable, the remaining unleased space occupied within three years, and any space still not occupied brought into use within ten years, under 13 CFR 120.131.
A 7(a) loan can also fund new construction as part of a broader project, particularly when it is bundled with equipment or working capital rather than a stand-alone build. See SBA loans for commercial real estate for the full 504 structure, the 50/40/10 financing split, and the job-creation requirement tied to the debenture.
Equity, and a common misconception
A new construction project does not automatically require more equity than buying an existing building. SBA’s higher equity tiers, roughly 15% instead of 10%, key off whether the business is a startup (in operation under two years) or the property is a special-purpose type (a hotel, gas station, or similar unique-use building), not whether the building is newly built. An established business constructing a general-purpose building, an office or a standard warehouse, still sits in the standard 10% tier. Combine a startup with a special-purpose new build and the requirement can reach 20%. See SBA loan down payment and equity requirements for the full breakdown.
If you run a construction company
A different, and much larger, part of our data covers businesses whose primary trade is construction (NAICS sector 23), whether or not the loan has anything to do with a building project. Since FY2010, SBA lenders funded 113,705 loans to construction-sector businesses, totaling $35.1 billion at an average of $308,578, well below the real-estate-driven averages elsewhere in our data, a sign these loans skew toward vehicles, equipment, and working capital rather than property. See the full breakdown, lenders and states included, on our construction industry data page.
Construction stands out on one measure in particular: it supports 28.7 jobs per $1 million of SBA financing, the second-highest of the sectors we track, behind only Administrative and Support. See which industries create the most jobs per SBA dollar for the full ranking. The Huntington National Bank is the sector’s most active lender on both measures, 11,855 loans and $2.0 billion; U.S. Bank (9,975 loans) and Wells Fargo Bank (5,815 loans) are also among its top lenders.
Getting to a lender
Whether you are financing a build or financing the business, lender activity varies a lot by deal type: a bank active in construction-company working capital is not necessarily set up for a ground-up 504 project, and vice versa. Run the numbers with the SBA 504 loan calculator, then get a shortlist of lenders that actually fund deals like yours through get matched, built on funded-loan track records, not who pays for placement.
Before you rely on this
Occupancy rules, equity tiers, and CAPLine terms follow the current SBA SOP and change over time; the figures above reflect SOP 50 10 8, effective June 1, 2025. Industry-level lending patterns describe a cohort of loans, not a guarantee for any individual application. Confirm current requirements with a participating lender or CDC before you commit to a project.
