SBA Owner Occupancy Requirements: The 51 Percent Rule
You may lease out up to 49 percent of an existing building bought with an SBA 7(a) or 504 loan, but SOP 50 10 8.1 keeps the tenant's anticipated rent out of projected debt service coverage on a Standard 7(a) loan and out of repayment ability on a 504 loan. 13 CFR 120.131 sets the thresholds: 51 percent of an existing building, 60 percent of new construction. On a Standard 7(a) loan (greater than $350,000) projected coverage "may not include anticipated cash flow from rental income from the Project Property"; on a 504 loan that rent "must not be included in the repayment ability analysis". Both chapters allow it in the global cash flow analysis. With assumed figures, a deal at 1.50 with the rent sits at 1.11 without it, below the 1.15 both chapters require.
This is general information, not legal or lending advice. We are not a lender, a Certified Development Company or attorneys. The rent exclusion is verified for Standard 7(a) projections and 504 repayment ability, not for 7(a) Small, SBA Express or MARC loans or for rent already being received. A 7(a) change of ownership follows Appendix 15 of the SOP, with its own coverage ratios. Confirm your layout and coverage with your lender or CDC before you sign a contract.
What is the SBA owner occupancy requirement?
The SBA owner occupancy requirement is that your business occupy at least 51 percent of an existing building, or 60 percent of a new one, financed with a 7(a) or 504 loan. SOP 50 10 8.1 applies it when loan proceeds buy or improve real estate or refinance debt secured by it.
13 CFR 120.131(b), for an existing building:
the Borrower may permanently lease up to 49 percent of the Rentable Property if the Borrower permanently occupies and uses no less than 51 percent of the Rentable Property
The restrictions "apply regardless of whether the Rentable Property is leased to a commercial or residential tenant". In an existing building zoned for both uses, a residence you occupy counts as occupied by the business only if it meets zoning requirements and "the nature of the business requires a resident owner or manager"; its square footage "must be appropriate to the needs of the business and may not exceed 49% of the total property".
How is SBA 51 percent owner occupancy calculated?
The 51 percent is measured on Rentable Property, which 13 CFR 120.10 defines as "the total square footage of all buildings or facilities used for business operations" and the SOP measures "excluding stairways, elevators, and mechanical areas and including common areas". A usable-space measure that strips out common areas is not the SOP's method.
Two more sentences say may. "To determine the occupancy percentage allocated to the Applicant or OC(s), the SBA Lender may include the square footage of all common areas." And "Rentable Property may also include exterior space (except parking areas) that is actively used in Borrower’s business operations", such as a contractor's storage yard.
Worked example, all figures assumed, in square feet. An existing building is 10,000 gross. Stairways, elevator and mechanical room take 600, so Rentable Property is 9,400. The business uses 4,200, common areas are 800 and a tenant leases 4,400.
| Measurement | If the lender credits all common areas to you | If it credits none |
|---|---|---|
| Applicant's share | 4,200 + 800 = 5,000 | 4,200 |
| Occupancy | 5,000 / 9,400 = 53.19 percent | 4,200 / 9,400 = 44.68 percent |
Crediting common areas to your share is our reading of the common-area sentence, and the word is may. The 51 percent line is 9,400 x 0.51 = 4,794: 3,994 of your own space with the credit, 4,794 without. Get your lender's or CDC's measurement in writing before you sign.
What is the SBA 60 percent rule for new construction?
The SBA 60 percent rule for new construction is 60 percent occupied, up to 20 percent permanently leased, and the rest used in stages over three and ten years. It is not 80 percent within two years. SOP 50 10 8.1:
For new construction, the Applicant must occupy 60% of the Rentable Property, may permanently lease to a third party up to 20% and temporarily lease an additional 20% with the intention of using some of the additional 20% within 3 years and all of it within 10 years.
| Source | Space held for growth |
|---|---|
| 15 U.S.C. 696(4), 504 statute | "up to 33 per centum of the total project may be leased, if reasonable projections of growth demonstrate" a need within three years and full use within ten |
| 15 U.S.C. 636(a)(28), 7(a) statute | none stated; 60 and 20 percent only |
| 13 CFR 120.131(a) | no figure: some of the remaining space within three years, all within ten |
If your layout needs a temporary lease above 20 percent, get your lender's or CDC's reading in writing. On 20,000 square feet under the SOP: occupy 12,000, lease up to 4,000 permanently, hold up to 4,000 for growth and reach at least 16,000 (80 percent) by year ten. Our reading is that a 504 plan should show the growth its statute asks for; see our SBA 504 loan requirements page.
Does rental income count toward an SBA loan?
Anticipated rental income from the Project Property may be included in the global cash flow analysis, but not in projected debt service coverage on a Standard 7(a) loan or in the repayment ability analysis on a 504 loan.
For Standard 7(a) loans, Section B, Chapter 1 of the SOP requires a debt service coverage ratio "equal to or greater than 1.15 on a historical and/or projected cash flow basis and 1:1 on a global basis", and says that rent "may be included in the global cash flow analysis". But:
For cash flow projections, the Lender must calculate the debt service coverage (which may not include anticipated cash flow from rental income from the Project Property)
For 504 loans, Section C, Chapter 1 says "Repayment ability is determined based on the operating company cash flow analysis." and "The DSC ratio must be equal to or greater than 1.15:1." Under Rental Income:
Anticipated cash flow from rental income from the Project Property may be included in the global cash flow analysis. However, it must not be included in the repayment ability analysis.
With assumed figures for a projected year:
| Line | With the tenant's rent | Rent left out |
|---|---|---|
| Operating cash flow of the business | $200,000 | $200,000 |
| Anticipated rent from the tenant | $70,000 | excluded |
| Annual debt service on all business debt | $180,000 | $180,000 |
| Projected debt service coverage | 270,000 / 180,000 = 1.50 | 200,000 / 180,000 = 1.11, below 1.15 |
At 1.15 the business needs $180,000 x 1.15 = $207,000 of its own cash flow, $7,000 more than it has, and the excluded rent does not count.
That 1.15 is for a Standard 7(a) loan that is not a change of ownership, and for a 504 loan. Buying a business with its building on a 7(a) loan falls under Appendix 15, which tests historical or adjusted statements at 1.25:1 for an Initial Acquisition, Owner Buyout or ESOP and Cooperative and 1.15:1 for a Business Expansion (see our SBA business acquisition loan requirements page); which basis applies is on our SBA debt service coverage requirements page.
Can an SBA loan pay for improvements to space you rent out?
No, SBA loan proceeds may not improve space you will sublease. "The Borrower may not use loan proceeds to improve or renovate any of the Rentable Property to be subleased to a third party." For 504 loans, 13 CFR 120.871 adds: "The costs of interior finishing of space to be leased out to another business are not eligible Project costs." And "Third-party loan proceeds used to renovate the leased space do not count towards the 504 first mortgage requirement or the Borrower's contribution".
The 4,400 sq ft tenant suite above, at an assumed $40 per sq ft of finishing, is 4,400 x 40 = $176,000 that SBA loan proceeds may not pay for. We have not surveyed build-out costs; the figure moves with the market and the lease.
How long do you have to occupy the building after an SBA loan closes?
You have at most 1 year after an SBA loan closes, where circumstances justify a delay, "such as when a pre-existing lease may have a few more months to run". "In no case may the small business have more than 1 year to meet occupancy requirements."
On a 504 loan, "CDCs must not submit a 504 closing package if the Borrower will not be occupying and operating in the required amount of Project property after closing and funding" unless the Sacramento Loan Processing Center approved more time in advance on the CDC's written request. A 504 debt refinance without expansion is tested earlier: "Borrower must meet all current 504 Loan Program occupancy requirements at time of application."
Can a holding company own the building (Eligible Passive Company)?
A holding company can own the building as an Eligible Passive Company (EPC) leasing to your Operating Company (OC), and the occupancy test falls on the operating business: "The OC(s) must lease 100% of the property from the EPC, but it can sublease a portion of the property under the rules governing occupancy requirements with which all SBA Borrowers must comply".
13 CFR 120.111(a) sets six conditions. The SOP says "each condition is interpreted strictly" and, if they are not all met, on default on a 7(a) loan "SBA may deny liability on the guaranty". One is a rent cap: "The rent or lease payments cannot exceed the amount necessary to make the loan payment to the lender, and an additional amount to cover the Eligible Passive Company's direct expenses of holding the property, such as maintenance, insurance and property taxes". Entity structure is a legal and tax question for your attorney and CPA.
Can a landlord or real estate investor get an SBA loan?
A passive landlord or real estate investor is an ineligible business under 13 CFR 120.110(c), which lists:
Passive businesses owned by developers and landlords that do not actively use or occupy the assets acquired or improved with the loan proceeds (except Eligible Passive Companies under § 120.111)
SOP 50 10 8.1 adds: "Businesses that are primarily engaged in owning or purchasing real estate and leasing it for any purpose are not eligible." The full list is on our SBA ineligible businesses page. If rental income is the business, see our real estate investment business plan.
What does your business plan have to show?
On our reading, a business plan for an SBA-financed building with a tenant has to show three things: coverage from the operating business alone, a square footage schedule and, on new construction, growth that fills the held space.
- Coverage. Historical coverage, plus projections that reach the required ratio without anticipated rent from the Project Property.
- Square footage. Gross area, exclusions, common areas, exterior space, your space, each tenant's space and the percentage of Rentable Property, repeated at years three and ten for new construction.
- Growth. The assumptions behind using some of the held space within three years and all of it within ten.

Frequently asked questions
What is the SBA 51 percent rule for owner-occupied real estate?
Under 13 CFR 120.131(b), when SBA 7(a) or 504 financing is for the acquisition, renovation or reconstruction of an existing building, the Borrower must permanently occupy and use at least 51 percent of the Rentable Property and may permanently lease up to 49 percent.
Can I rent out part of my building with an SBA loan?
Yes. Under 13 CFR 120.131 and SOP 50 10 8.1 you may permanently lease up to 49 percent of an existing building, or 20 percent of new construction, financed with a 7(a) or 504 loan. Loan proceeds may not improve space you sublease.
Does the SBA count tenant rent toward debt service coverage?
On a Standard 7(a) loan, SOP 50 10 8.1 keeps anticipated rent from the Project Property out of projected debt service coverage; on a 504 loan, out of the repayment ability analysis. Both chapters allow it in the global cash flow analysis.
Does the apartment above my shop count as occupied by the business?
An apartment you live in counts as occupied by the business only if the nature of the business requires a resident owner or manager and zoning requirements are met. SOP 50 10 8.1 then caps it at 49 percent of the total property; otherwise the SOP does not treat it as occupied by the business.
Is the occupancy rule different for 7(a) and 504 loans?
The occupancy percentages are the same: 13 CFR 120.131 covers 7(a) and 504 alike, and neither program's proceeds may improve space to be subleased. The 504 side adds 13 CFR 120.871 on tenant finishing and a closing package that waits for occupancy.
