The 504 program has stricter eligibility than 7(a), because it is an economic development program that happens to be delivered as a loan. Beyond the general SBA tests, the project itself must qualify: what it buys, who occupies it, what it does for jobs, and how much the borrower puts in. This guide sets out each requirement with its source in federal regulation or the SBA’s SOP, then shows what the record of 116,345 funded 504 loans looks like.
The business tests
A 504 applicant must meet the same baseline as any SBA borrower: an operating, for-profit business located in the United States, not an ineligible type, creditworthy, and without a prior loss to the federal government. The SBA’s 504 page adds “qualified management expertise, a feasible business plan, good character and the ability to repay.”
Size is where 504 differs in practice. A business qualifies either under the standard NAICS size standard for its industry or, under 13 CFR 121.301(b), if it and its affiliates have a tangible net worth of $20 million or less and average net income after federal taxes of $6.5 million or less for the last two fiscal years. That alternative test brings in many businesses too large for their industry standard, which is one reason 504 borrowers skew larger and more established. The size standard tool checks the industry test.
What the project can be
Proceeds must fund fixed assets: purchasing land or existing buildings, constructing or improving facilities, and buying long-term machinery and equipment with a remaining useful life of at least 10 years, along with the soft costs that go with them, such as appraisals, environmental studies, title, and construction contingency up to 10%. Working capital, inventory, and speculative or rental real estate are excluded. Refinancing is allowed only under the conditions in 13 CFR 120.882: existing debt tied to eligible fixed assets can be folded into an expansion project up to the expansion’s cost, and debt on a stand-alone basis can be refinanced without expansion if the business has operated for the entire two years before applying, has been current for at least a year, and gains a substantial benefit.
Owner occupancy
The building must be owner-occupied, and 13 CFR 120.131 defines it precisely:
| Project | Borrower must occupy | May lease to others |
|---|---|---|
| Existing building (purchase, renovation, reconstruction) | At least 51% of rentable property | Up to 49% |
| New construction | At least 60% at completion, some of the remainder within 3 years, all but 20% within 10 years | Up to 20% permanently |
A property that fails the occupancy test is an investment property, and the SBA does not finance those under either program; see SBA loans for real estate investing.
The economic development test
Every 504 project must achieve at least one economic development objective under 13 CFR 120.860 through 120.862. The default is job creation or retention: under SOP 50 10 8, at least one job opportunity per $90,000 of debenture, or per $140,000 for small manufacturers (primary NAICS code in sectors 31 to 33, all production in the U.S.) and for projects meeting an energy public-policy goal. The jobs need not be at the project site, but 75% must be in the community where the project is located, and job retention counts only where the CDC can show the jobs would otherwise be lost.
A project that will not meet the jobs number can still qualify if it meets a community development goal (improving or diversifying the local economy, stimulating other business development, bringing new income into the community, assisting manufacturers, or assisting businesses in a labor surplus area) or a public policy goal, including revitalizing a business district with a written plan, expanding exports, expanding businesses owned by women, veterans, or minorities, aiding rural development, modernizing to meet health or environmental requirements, cutting energy consumption by at least 10%, or investing in renewable energy. When a project qualifies on a goal rather than jobs, the CDC’s overall portfolio must still meet its job-opportunity average. How much employment SBA lending actually supports, measured from the record, is in jobs per SBA dollar.
The money you bring
13 CFR 120.910 sets the borrower’s minimum contribution as a share of project cost:
| Situation | Minimum contribution |
|---|---|
| Standard project | 10% |
| Business has operated for two years or less | 15% |
| Limited or single-purpose building (for example, a hotel, gas station, or car wash) | 15% |
| Both conditions | 20% |
The contribution may be cash, property bought with cash, or land that is part of the project, from any source except another SBA business loan. The CDC/SBA debenture may not exceed 40% of project cost under 13 CFR 120.930, may not be less than $25,000, and is capped at $5 million per project, or $5.5 million for small manufacturers and energy public-policy projects. The bank’s first-lien loan covers the balance, typically 50%. Since July 4, 2026, a borrower who secures a 7(a) loan first may hold up to $5 million in 504 financing alongside it; see SBA loan limits.
Repayment, guarantees, and collateral
The CDC’s credit analysis must address debt service coverage, defined as operating cash flow divided by all business debt payments including the new financing. SOP 50 10 8 requires coverage of at least 1 to 1 on the CDC’s analysis, with projections examined where history falls short; SOP 50 10 8.1, effective October 1, 2026, raises the standard to 1.15 to 1 on historical cash flow using the last fiscal year or a two-year average. Every owner of 20% or more guarantees the loan under 13 CFR 120.160. Collateral is the project itself: the bank takes a first lien and the CDC a second lien on the property or equipment financed, and additional collateral may be required where the project alone is not enough. That structure shows in the record: 98.4% of 504 loans were secured at approval, against 75.9% of 7(a) loans.
What the record shows
Of the 1,036,074 SBA loans funded from fiscal year 2010 through March 31, 2026, 116,345 were 504 loans, 11.2% of the total. The median stated term is 240 months, the standard 20-year real estate debenture. The borrowers are concentrated in the industries that own their premises: hotels, gas stations with convenience stores, car washes, self-storage, veterinary practices, and child care centers lead the loans approved at the SBA’s maximum in who hits the $5 million ceiling, and biggest SBA loans by industry ranks average loan size by sector across both programs. The 504 vs 7(a) comparison shows how the two programs differ in size, term, and outcome across the record.
How a 504 application works
You apply through a Certified Development Company serving the project’s area, which packages the SBA portion and coordinates with a bank or credit union that provides the first lien and, usually, interim financing until the debenture is sold. The CDC is a nonprofit certified by the SBA and is paid a processing fee of up to 1.5% of the debenture, covered in SBA 504 loan fees. Which CDCs actually fund projects in your state, ranked by volume from the SBA’s record, is on the certified development companies page, and the 504 calculator models the bank and debenture payments at the current fixed rate. For the program mechanics, read the 504 loan explained.
Eligibility rules follow the SBA regulations and the SOP in effect when the SBA issues a loan number; SOP 50 10 8.1 applies from October 1, 2026. Confirm specifics with a CDC before you plan around them.
