Quick answer
As of November 2026, an SBA loan for an existing building requires your business to occupy at least 51% of the rentable property, and you can lease out up to 49%. For new construction it's 60%, with 20% leased permanently and 20% temporarily. A holding company can own the building if it leases 100% to your operating company.

The Rule in One Table
13 CFR 120.131 and SOP 50 10 8.1 set the occupancy test whenever SBA money buys, improves or refinances real estate. It is what separates an owner-occupied loan from an investment property, and it applies to the 100% structure in 100% SBA financing.
| Existing building | New construction | |
|---|---|---|
| Your business must occupy | At least 51% | At least 60% |
| Permanent lease to others | Up to 49% | Up to 20% |
| Temporary lease to others | Not needed | Up to 20% more |
| Temporary space deadline | None | Use some within 3 years, all within 10 |
The lender can give up to one year after closing to reach occupancy, for example while a tenant's existing lease runs out. Never more.
What Counts as Rentable Property
The SOP defines rentable property as the total square footage of buildings used for business operations, excluding stairways, elevators and mechanical areas and including common areas. Exterior space can count if it's actively used, like a contractor's storage yard or a marina's slips, but parking doesn't. The lender may give your business the square footage of common areas.
That choice can decide a close deal. Take a 12,000 sq ft building with 600 sq ft of stairs, elevator and mechanical rooms, leaving 11,400 rentable. You use 5,400 sq ft and a tenant uses 5,400 sq ft, and there is a 600 sq ft shared lobby.
| How it's counted | Your share | Result |
|---|---|---|
| Lobby credited to you | 6,000 / 11,400 = 52.6% | Passes |
| Lobby not credited to you | 5,400 / 11,400 = 47.4% | Fails |

Holding Company Ownership (EPC/OC)
Many owners hold the building in a separate LLC. The SBA allows this as an Eligible Passive Company (EPC) that leases to your Operating Company (OC), under strict conditions:
- The EPC must lease 100% of the property to the operating company, which then occupies at least 51% (or 60% new) and can sublease the rest.
- The EPC can't do any other business, and rent can't exceed the loan payment plus the EPC's direct costs of holding the property.
- The EPC assigns its rents to the lender as collateral.
- Every owner of 20% or more of either company guarantees the loan.
- Only one EPC per transaction, though several properties can be in it if they're all leased to the same operating companies.
Spaces That Trip Buyers Up
- Residential units. In a mixed-use building, residential space can be rented out within the 49%. An owner's apartment only counts as the business's if the business needs someone on site, like livestock care, and it can't exceed 49% of the property.
- Tenant space improvements. SBA proceeds can't improve space you lease to others. See tenant improvements in an SBA purchase.
- Illegal tenants. Leasing to a business that is illegal under any law, including federal law, such as a marijuana dispensary, is not allowed for the life of the loan.
- Yards. See financing a contractor's yard for how outdoor space counts.
If You Can't Reach 51%
A building where your business would use less than half is an investment property to the SBA. The options are a conventional or real estate secured loan, a smaller building, or a plan to take back tenant space within a year of closing.

Frequently Asked Questions
What is the SBA 51% occupancy rule?
For an existing building bought, improved or refinanced with an SBA loan, your business must occupy at least 51% of the rentable property. You may lease the rest to others.
What is the occupancy requirement for new construction?
60%. You can lease up to 20% permanently and another 20% temporarily, if you plan to use some of that space within 3 years and all of it within 10.
Do common areas count toward my 51%?
The lender may include common areas in your share. Stairways, elevators and mechanical areas are excluded from the total, and parking doesn't count.
Can my real estate LLC own the building?
Yes, as an Eligible Passive Company, if it leases 100% to your operating company, does no other business and charges rent no higher than the loan payment plus holding costs.
How long do I have to meet occupancy?
The lender can allow time after closing, for example while an existing tenant's lease ends, but never more than one year.
Does the rule apply to SBA 504 loans too?
Yes. Both 7(a) and 504 use the same 51% and 60% rules.
