Yes, an SBA 504 loan can finance a multi-tenant building, as long as your business is the primary occupant and the other tenants are secondary. For an existing building, your company must permanently occupy at least 51% of the rentable space. For new construction, the minimum is 60% at the start. The program is built for owner-occupied property, not for buying a building mainly to collect rent.
This guide explains how the occupancy test works, how the down payment and financing split are set up, what you can and cannot pay for, and how to prepare a multi-tenant deal before you meet a Certified Development Company (CDC).

Can SBA 504 finance a building with other tenants?
The SBA describes the 504 program as long-term, fixed-rate financing for major fixed assets that promote business growth and job creation. It can fund the purchase, construction or renovation of existing buildings. It cannot be used for speculation or for investment in rental real estate.
That last restriction is what shapes every multi-tenant deal. The building has to be a home for your business first. Tenants are allowed because many owner-users buy more space than they need today, and renting the surplus is a sensible way to carry the building while the company grows into it.
A few examples show where the line falls:
The occupancy rules: 51% and 60%
The rule sits in the SBA’s regulations at 13 CFR 120.131, and it differs by project type.
Project typeMinimum occupancy at closingPlan for remaining spaceExisting building51% of the total rentable property, permanentlyYou may lease up to 49%New construction60% of the rentable propertyPlan to occupy some of the rest within three years, and all space not permanently leased within ten years
The eCFR text of Subpart H states the same thresholds: at least 51% permanently occupied for an existing building, and at least 60% immediately for new construction, with expansion into more space over time.
What counts as rentable space
The percentage is measured against rentable property, not just the suite numbers on a lease. Under the SBA’s operating procedures, rentable space includes common areas and may include actively used exterior space other than parking, while stairways, elevators and mechanical areas are excluded. Because the SOP can be revised, ask your CDC which version applies to your application. A building that looks like a 48% deal on leasable square footage can sometimes read differently once common areas are allocated, and the reverse is also true. Get a floor plan and a square-footage breakdown from the seller or an architect before you sign a purchase agreement.
Occupancy by affiliates
Many owner-users operate through more than one company. One entity may hold the real estate while another operates the business. The structure of your ownership and operating entities affects how the occupancy is counted, so bring your entity chart to the first conversation. Our 51% occupancy eligibility guide walks through how New England borrowers typically document it.
Who and what qualifies
The borrower must be an operating, for-profit business located in the United States that meets SBA size standards, according to the SBA. Applicants disclose 100% of the business’s ownership on the SBA application form, so every owner should expect to be named.
Proceeds are for fixed assets. Eligible uses include:
Not eligible: working capital, inventory, speculation, and investment in rental real estate. If the build-out of your own space also needs machinery, that equipment can sit inside the 504 project. If you also need a separate equipment financing arrangement for items outside the project, keep it separate from the real estate budget so the 504 numbers stay clean.
How the financing is structured
The SBA explains that you apply through a CDC, which packages the project after a third-party lender commits to finance 50%. A typical project looks like this:
SourceShare of projectLien positionThird-party bank50%First lienCDC (SBA-backed debenture)Up to 40%Second lienBorrowerAt least 10%Equity contribution
The SBA notes that startups and special-purpose projects call for a higher borrower contribution. Our 50/40/10 structure guide shows who pays what and when during construction and at closing.
How the down payment is determined
The 10% figure is the floor, not a promise. Four things move it:
An example with round numbers: on a $2,000,000 project for an established business buying a general-purpose building, your minimum contribution is $200,000. If the same building is special-purpose, the contribution rises and the CDC portion shrinks. Ask your CDC to run both versions before you make an offer.
If cash is your constraint, our Down Payment Assistance Program is designed to help New England borrowers close that gap on commercial property.
How the rental income from tenants fits in
Tenants do not make the loan an investment property. They do, however, help the building pay for itself. Lenders will typically look at your business’s repayment ability first, and they may also look at the lease income from tenants as part of the overall picture. Practical points that help your file:
Tenant improvements for those tenants are a separate question from your own build-out, so discuss the budget line by line with your CDC.
Fixed rates and terms
The CDC portion carries a fixed rate for the life of the loan, which is the main reason owner-users choose 504 over a floating-rate bank loan. On our site, the rates published as of September 2026 were:
ProgramFixed rateEquipment, 10-year6.58%Real estate, 20-year6.73%Real estate, 25-year6.77%
These are the rates we published on that date. Rates move with the market, so check the current rates on our site before you model a deal. For a multi-tenant building, the 25-year option usually produces the lowest monthly payment, which matters when part of your income depends on tenants renewing. We compare the choices in our 10, 20 and 25-year terms guide.
Refinancing a multi-tenant property
If you already own the building, a 504 loan may refinance qualified debt under 13 CFR 120.882, according to the SBA. Debt that does not meet the qualified-debt definition cannot be refinanced. The occupancy rule still applies to the owner-user, so a building where you occupy less than half will not qualify just because the debt is old. Our guide to refinancing commercial real estate with an SBA 504 loan lists the documents to gather, and the refinance vs. recast comparison helps if you are weighing a faster paydown.
A preparation checklist
Before you contact a CDC on a multi-tenant deal, assemble:
Completeness speeds things up. Our Premier Certified status is intended to support faster approvals, and a clean file helps you take advantage of it.
Perspective: why owner-users should plan the tenant mix early
We see the same pattern in New England deals again and again. A growing company finds a building that is larger than it needs, and the owner worries that the extra space disqualifies the project. It usually does not. The 51% and 60% thresholds exist so that businesses can buy the space they will grow into, and renting the rest in the meantime is a normal, legitimate way to carry it.
Our advice is to treat the occupancy percentage as a design decision, not a hurdle. Decide how much space you need now and how much you want in five years, then match the lease terms to that plan. A tenant on a three-year lease in the space you intend to take over is far easier to manage than one with a ten-year term.
We also encourage borrowers to compare total cost, not just the first-year payment. With a 10% minimum contribution, a fixed rate for up to 25 years, and a structure that keeps your bank line and working capital free for operations, 504 is designed to let you own the building without starving the business. Bring us the floor plan before you bring us the offer, and we will tell you where you stand.

FAQ
Can I buy a multi-tenant building with an SBA 504 loan if I only need a small part of it?
Only if your business will permanently occupy at least 51% of the rentable space in an existing building. If you need less than that, the project is closer to rental real estate investment, which the program does not fund. You could look at a smaller building or plan to expand into more of the space.
Do the other tenants’ leases have to be short-term?
The regulations do not set a single lease length for every case. They do set expectations for new construction: you must plan to occupy more space within three years and all space not permanently leased within ten years. Match your lease terms to your growth plan and confirm the details with your CDC.
Is the down payment always 10%?
Ten percent is the minimum for a typical project. The SBA says higher contributions apply to startups and special-purpose projects, and the first-lien lender may ask for more based on your finances. Ask for a quote on both the minimum and a conservative scenario.
Can I refinance the existing loan on a building where I already have tenants?
Possibly. A 504 loan can refinance qualified debt, and debt that does not meet the qualified-debt definition cannot be refinanced. You must also meet the occupancy rule as the owner-user, and your CDC can review your existing note to see whether it qualifies.
