SBA 504 Loan Uses: Real Estate, Equipment, and Refinancing

SBA 504 loan uses are limited to long-term fixed assets: buying owner-occupied commercial real estate, constructing new facilities, renovating or modernizing buildings you already own, and purchasing heavy machinery or equipment with a useful life of at least 10 years. The program also covers related soft costs like appraisals and engineering fees, and it permits refinancing of qualifying business debt under specific rules. The SBA-guaranteed portion caps at $5 million for most projects and $5.5 million when the project meets certain energy-efficiency goals.¹ Working capital, inventory, and vehicles fall outside the program entirely.

Buying Commercial Real Estate

The most common use of 504 financing is purchasing commercial property where your business will operate. If you’re buying an existing building, your business must occupy at least 51% of the total rentable square footage. The remaining space can be leased to tenants as long as you maintain that threshold. Land purchases qualify when the land is part of a larger project, such as buying a parcel where you plan to build.

The occupancy requirement is what keeps the program from funding passive investment properties. You’re converting rent payments into equity in a building your business actually uses. Office buildings, warehouses, retail storefronts, and manufacturing facilities that house the primary operations of the business all fit here.

Constructing a New Facility

Ground-up construction is fully eligible, but the occupancy bar sits higher than for existing buildings. You must occupy at least 60% of the space when construction is complete, with the expectation that occupancy reaches 80% within 10 years. The gap reflects the reality that a business building to its future needs won’t fill every square foot on day one.

The loan covers more than the building shell. Site preparation costs count as eligible project expenses, including grading for drainage, running utility connections for water, sewer, and electricity, and building out parking areas, curbs, and sidewalks. A contingency reserve of up to 10% of construction costs can also be included to cover overruns.²

Interest and fees on interim construction financing can be rolled into the total project cost as well. During construction, a separate short-term loan typically funds progress payments to contractors. The interest that accrues on that interim loan before the 504 debenture closes is a recognized project cost, so it doesn’t have to come entirely out of pocket.

Renovating and Modernizing an Existing Building

You don’t need to buy or build to use a 504 loan. Renovating a facility you already own is a frequent and straightforward application of the program. Eligible projects range from structural repairs and roof replacements to upgrading HVAC systems, electrical panels, or plumbing to bring an older building up to current standards. The improvement has to be tied to the building’s operational capacity or long-term viability.

Projects that meet certain energy goals get a meaningful incentive: the maximum SBA debenture increases from $5 million to $5.5 million per project, with an aggregate cap of $16.5 million for the same business owner. Qualifying projects include reducing existing energy consumption by at least 10%, generating more than 15% of the facility’s energy from renewable sources, or incorporating sustainable design features that cut reliance on fossil fuels.¹ If you’re already planning a renovation, checking whether your project hits one of these thresholds is worth the effort for the extra borrowing capacity alone.

Long-Term Machinery and Equipment

Heavy machinery and specialized equipment qualify for 504 financing as long as the asset has a remaining useful life of at least 10 years.¹ That floor keeps the financing term aligned with the asset’s productive life. Equipment loans carry a 10-year maturity to match.

The kinds of equipment that typically qualify are the big-ticket items a business can’t easily fund from cash flow: industrial presses, CNC machines, commercial ovens for a bakery or food-processing plant, and imaging equipment like MRI or CT scanners for medical practices. The SBA specifically notes that project-related AI-supported equipment or machinery used in manufacturing is eligible.¹

Short-term equipment, office furniture, and furnishings are generally excluded unless they’re essential to the project and represent a minor portion of total costs.³ If you’re outfitting a new facility and need a small amount of furniture alongside major equipment purchases, the furniture might be included. You can’t build a 504 project around desks and chairs.

Soft Costs Bundled Into the Project

The program covers certain professional fees directly tied to completing the project. These include architectural and engineering costs, appraisals, environmental studies, title insurance, and legal fees related to zoning, permits, or platting.² If you’re buying or building commercial property, you’ll incur most of these costs regardless, so folding them into long-term fixed-rate financing rather than paying them at closing is a real advantage.

Two costs that catch borrowers off guard are the commercial appraisal and the Phase I environmental site assessment, both of which the SBA typically requires. Commercial appraisals commonly run in the range of $2,000 to $4,000, and a Phase I environmental assessment for a standard commercial property usually falls between $2,000 and $4,500, with higher-risk sites like gas stations or dry cleaners costing substantially more. These are part of the project cost, not extras you cover separately.

Soft costs that have nothing to do with acquiring or building the fixed asset are ineligible. Advertising, franchise fees, counseling or management services, and incorporation costs all fall outside the scope of a 504 project.³

Refinancing Existing Business Debt

The 504 program allows refinancing of existing business debt under rules set out in federal regulations, with two distinct paths depending on whether the project also involves expansion.⁴

Refinancing With Expansion

If your project includes expanding the business, you can fold existing debt into the total project cost. The amount of debt refinanced cannot exceed 100% of the expansion’s project cost. If you’re spending $600,000 on a building addition, you can refinance up to $600,000 of qualifying existing debt as part of the same loan.⁴ The original debt must have been used to acquire or improve assets that would have been eligible under the 504 program, and it must be secured by eligible fixed assets. The borrower needs to have been current on all payments for at least one year before the refinancing date.

Refinancing Without Expansion

A standalone refinancing with no expansion component has tighter requirements. The debt being refinanced must be a “qualified debt,” meaning a commercial loan that was incurred at least six months before the application date, taken out for the benefit of the small business, and secured by eligible fixed assets.² The business must have been operating for the full two years preceding the application date.

Standalone refinancing also allows limited cash out for eligible business expenses, provided the loan-to-value ratio stays at or below 85% and the cash-out portion doesn’t exceed 20% of the property’s fair market value. Eligible expenses include salaries, rent, utilities, and inventory costs that are currently due or will come due within the next 18 months. Business credit cards and lines of credit qualify as long as they’re in the operating company’s name and the debt was incurred exclusively for business purposes. Personal expenses cannot be refinanced under any circumstances.²

What a 504 Loan Cannot Cover

The boundaries are worth knowing early, because they shape how you structure the rest of your financing. The following are ineligible for 504 proceeds:

Working capital and inventory. These are short-term operational needs that don’t fit a long-term fixed-rate loan. If you need working capital alongside your 504 project, an SBA 7(a) loan or a conventional line of credit is the typical companion.
Automobiles, trucks, and airplanes. Vehicles are explicitly excluded, even commercial ones like delivery vans or company trucks.³
Speculation or rental real estate. The program funds properties your business occupies, not investment properties you plan to lease out entirely.¹
Personal debt. Any debt not incurred for the benefit of the business is off limits.
Non-qualifying debt consolidation. You can’t refinance debt that doesn’t meet the qualified-debt definition described above.
Construction equipment. Excluded unless it’s heavy-duty equipment integral to the business’s core operations with at least 10 years of remaining useful life. A general contractor can’t finance a backhoe through a 504 loan, but a demolition company whose entire business depends on heavy equipment could potentially qualify.³

The SBA also specifically prohibits using 504 proceeds for AI-related working capital, intellectual property, or consulting services, a newer carve-out as AI-supported equipment for manufacturing has become an eligible asset class.¹ The hardware qualifies; the software subscriptions and consulting contracts around it do not.
