Can You Get an SBA Loan for an Apartment Building? The Passive Real Estate Rule, the 51 Percent Exception, and the USDA Section 538 Route

Concrete and glass apartment building with lit units and balconies at dusk

The answer is no, and the reason it keeps getting asked is that a meaningful share of what Google returns says yes. Here is the sentence in the regulation that settles it, the exception that people stretch until it breaks, what the SBA does finance next door to housing, and the one federal guarantee program that is actually built for rural apartments.

Type "SBA loan apartment building" into a search engine and you will get a split verdict. Several of the pages that come back say plainly that the Small Business Administration does not finance apartment complexes. Others say the opposite. One real estate lending marketplace, in a page still live in September 2026, describes the SBA 504 program as "a reliable source for investors looking to acquire or renovate commercial real estate, including multifamily properties," and then tells those investors they "must commit to residing in one of the units as their primary residence." A landlord banking platform calls the 7(a) loan "the most ideal business loan for rental property investing in residential or commercial real estate." A mixed-use financing blog, published this March, assures readers that "the residential apartments count" toward the property a business can finance.

Every one of those claims runs into a regulation that is one sentence long, and into an SBA operating procedure that is blunter still. This piece lays out the rule as written, the owner-occupancy exception as it actually operates, the housing-adjacent businesses the SBA does finance, and the program a rural apartment developer should be reading about instead: USDA's Section 538 Guaranteed Rural Rental Housing Program, which is running at a $400 million annual program level and accepting applications on a continuous basis.

The rule, in the words of the regulation

The eligibility bar sits at 13 CFR 120.110, the section of SBA's business-loan regulations titled "What businesses are ineligible for SBA business loans?" Paragraph (c) excludes:

"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)." SBA's Standard Operating Procedure 50 10 8, effective June 1, 2025, turns that paragraph into operating language for lenders. In its chapter on ineligible business types it says: "Businesses that are primarily engaged in owning or purchasing real estate and leasing it for any purpose are not eligible." Two lines later it removes any doubt about the asset class at issue: "Apartment buildings and mobile home parks are not eligible." The SOP then closes the two escape routes that show up most often in loan applications. The first is the blended business, the borrower who owns apartments but also runs something else out of the building. The SOP's answer: "A business is either fully eligible or fully ineligible. If a business has a combined model (part of the revenue is from rent and part from membership dues), it is not eligible." The second is the ineligible landlord who wants an SBA loan for a different purpose, say a building for its own office. The SOP: "An ineligible business cannot obtain an SBA Loan for any purpose, including the purchase or construction of a building for its own use." The bar applies identically to 7(a) and 504. The 504 program adds a codified occupancy rule (13 CFR 120.131) and finances only fixed assets, but its eligibility chapter cross-references the same list of ineligible business types. Neither program has ever financed a rental apartment building as such, and SOP 50 10 8.1, issued August 14, 2026 and effective for applications assigned an SBA loan number on or after October 1, 2026, concentrates its changes on change-of-ownership lending. The passive-business bar and the occupancy percentages are not among the changes SBA announced.

The exception people misread

Almost every page that gets this wrong is misreading one real rule: owner-occupancy. It is worth stating precisely, because the boundaries are exactly where the confusion lives.

An operating small business may use SBA financing to buy or build the real estate it occupies, and it may lease out the part it does not occupy. For an existing building, the business must occupy at least 51 percent of the rentable property; up to 49 percent may be leased to others. For new construction, the business must occupy at least 60 percent on completion, may permanently lease no more than 20 percent, and must plan to occupy the balance within ten years. The structure that lets a real estate holding entity sit on title is the Eligible Passive Company under 13 CFR 120.111. An EPC "must use loan proceeds only to acquire or lease, and/or improve or renovate, real or personal property ... that it leases to one or more Operating Companies for conducting the Operating Company's business." The Operating Company must be a guarantor or co-borrower, and every holder of 20 percent or more of either entity must guarantee the loan. The EPC is a landlord to one tenant, the borrower's own business. It is not a landlord to the public. So the classic downtown building, a café on the ground floor and an apartment above, is eligible when the café's space is at least 51 percent of the rentable area and the café is the borrower. The apartment upstairs is incidental. The SBA is not financing the apartment; it is financing the café, and tolerating the apartment. Flip the proportions, two floors of apartments above a small retail bay, and the property fails the occupancy test outright.

There is a second constraint that the "rent out the other 49 percent" pages never mention, and it is the one that matters most to an underwriter. The rental income does not count toward repayment. For 7(a) loans, SOP 50 10 8 directs that when a lender calculates projected debt service coverage, the calculation "may not include anticipated cash flow from rental income from the Project Property." For 504 loans the SOP is equally explicit: 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." Repayment is determined "based on the operating company cash flow analysis." In practice, that means the operating business must clear SBA's 1.15 debt service coverage floor on its own, with the tenant's rent stripped out. A borrower who buys a building expecting the tenants to carry a third of the mortgage is not doing SBA math. That, more than any eligibility clause, is why the apartment fantasy dies in the credit memo even when the property technically passes the 51 percent test.

What the SBA does finance next door to housing

The dividing line is not "buildings people sleep in." It is active versus passive. An operating business that happens to house people overnight can be eligible; a landlord collecting rent cannot. Four categories sit on the eligible side of the line, each with its own test.

Hotels, motels, RV parks, marinas and campgrounds. These are eligible, the SOP says, "if more than 50% of the business's revenue for the prior year is derived from transients who stay for 30 days or less at a time and the business complies with all zoning and other legal requirements." A start-up must show the same 50 percent in its projections. The same passage extends to rentals booked through internet platforms: they "must be in compliance with all local laws and regulations, including zoning codes, and homeowners or condominium associations rules." A vacation rental portfolio operated as transient lodging, in a jurisdiction that permits it, can be an SBA business. A furnished apartment let by the month cannot. Hotel, RV park and campground eligibility under this test is the subject of its own guide on this site. Licensed care facilities. Assisted living, memory care and skilled nursing are operating businesses because they deliver services. The SOP draws the line at the license: "Residential facilities that are not licensed as nursing homes or assisted living facilities and do not provide healthcare and/or medical services are not eligible." An independent-living building with no services is, for SBA purposes, an apartment building. Licenses must be in hand within 90 days after final disbursement, and the loan cannot be sold into the secondary market until they are. Licensed assisted living is covered at length elsewhere on this site. Anything run by a third-party manager. A business "that has entered into a management agreement with a third party that gives the management company sole discretion over the business operations" is an ineligible passive business. Eligibility survives only where the applicant keeps "meaningful oversight": approving the operating budget and major expenditures, controlling the bank accounts, and employing the people who run the property. Hotel and senior housing sponsors who plan to hand the keys to an operator should read that paragraph before they read anything else. Mobile home parks. Excluded by name, in the same sentence as apartment buildings. Two of these categories carry a second cost. Under 13 CFR 120.910, the 504 program's base borrower contribution of 10 percent rises to 15 percent for a new business or for a Limited or Special Purpose Property, and to 20 percent where both apply. SBA's non-exhaustive special-purpose list includes "Hotels, motels, and other lodging facilities," "Nursing homes" including assisted living, and "Marinas." RV parks and campgrounds are not on the enumerated list, though the list "is not intended to be all-inclusive" and a CDC may classify them as special purpose in its credit memorandum.

Housing-adjacent business	SBA eligible?	The test
Apartment building, any size	No	Excluded by name; passive real estate under 13 CFR 120.110(c)
Mixed-use, business on ground floor, apartments above	Only as the business's loan	Business occupies 51% (existing) or 60% (new); rental income excluded from repayment analysis
Hotel, motel, extended-stay	Yes	More than 50% of revenue from stays of 30 days or less; zoning compliance
RV park, campground, marina	Yes	Same transient test; long-term site rentals erode eligibility
Short-term rentals via booking platforms	Yes, if operated as transient lodging	Transient test plus local law, zoning and HOA compliance
Assisted living, memory care, skilled nursing	Yes	State license required; unlicensed residential care is ineligible
Independent living with no services	No	Treated as apartments
Mobile home park	No	Excluded by name
Any property under a manager with sole discretion	No	Passive unless the applicant retains meaningful oversight

The program that says yes: USDA Section 538

If the apartment building is in a rural area, there is a federal guarantee designed for it. USDA Rural Development's Section 538 Guaranteed Rural Rental Housing Program, governed by 7 CFR Part 3565, guarantees private lenders' loans for "the construction, improvement and purchase of multi-family rental housing for low to moderate income families." It is the only federal guarantee that finances rental apartments as rental apartments, with no owner-occupancy fiction and no operating business required. The terms, from the regulation and USDA's program page:

Who can live there. Units must be occupied at initial move-in by households whose incomes "do not exceed 115 percent of the area median income." After that a tenant's income may rise without penalty. Rent on any unit, including tenant-paid utilities, is capped at 30 percent of 115 percent of AMI, and the project's average rent may not exceed 30 percent of 100 percent of AMI, adjusted for family size. These are workforce limits, not deep-subsidy limits; 115 percent of AMI reaches most of a rural county's working households. Where. Eligible rural areas as defined under section 520 of the Housing Act of 1949, checked address by address on USDA's eligibility map, plus federally recognized tribal lands. Projects need at least five units. How much. The guarantee covers up to 90 percent of the loan. For-profit borrowers may borrow up to 90 percent of total development cost or appraised value, whichever is less; nonprofits and public bodies up to 97 percent. Terms run from a 25-year minimum to a 40-year maximum at a rate "fixed over the term of the loan." Three guarantee options exist: a permanent-loan-only guarantee, a guarantee that attaches to construction advances and rolls into the permanent loan, and a single continuous construction-to-permanent guarantee reserved for projects with low loan-to-cost ratios. The Agency "will not guarantee construction loans only." What it costs. Under USDA's fee schedule effective April 4, 2022, the initial guarantee fee is 0.65 percent of the guaranteed amount for the standard structure and 0.60 percent for workforce housing (rents between 80 and 115 percent of AMI), for preservation of existing Section 515 and 514/516 properties, and for new construction or substantial rehabilitation meeting a green standard. The annual fee is 0.35 percent of outstanding principal for standard deals and 0.25 percent for the same three preferred categories. The application fee is a flat $2,500. Who lends. Lenders already approved and active with Fannie Mae, Freddie Mac, Ginnie Mae or HUD, Federal Home Loan Bank members, and state and local housing finance agencies are automatically eligible. The feasibility gate. Section 538 does not require an owner-occupied operating business, but it does require the lender to prove the market. Under 7 CFR 3565.303, a lender may request "a preliminary feasibility review by the Agency" during initial processing, and before a conditional commitment the lender must certify "compliance with the section 538 program's debt service coverage ratio requirement of at least 1.15, based on the lender's analysis of current market conditions and comparable properties in the project's market area." Section 3565.302 attaches a fee to that "site assessment and market analysis or preliminary feasibility" review. And 3565.213 gives the Agency a market-saturation veto: "If any of the Agency guaranteed loans in the market are experiencing vacancy rates in excess of 15% and the vacancy is due to market conditions, the Agency will invoke this provision and not guarantee the loan." In a year when the national apartment overhang is the story, that 15 percent clause is the one to check first. A multifamily feasibility study that documents comparable-property occupancy in the market area is therefore not optional paperwork on a 538 deal; it is the certification. Timing. Since a Federal Register notice effective December 20, 2024, Section 538 accepts lender applications "on a continuous basis," first come, first served, funded "to the extent an Appropriations Act provides sufficient funding in the fiscal year the application is selected." Applications that miss one year's money roll to the next. USDA's own guidance is that assembling the application "can take anywhere from a few weeks to several months." Money. Congress has held the Section 538 program level at $400 million in each of FY2023 through FY2026; the FY2026 figure was enacted in the November 2025 legislation that ended the federal shutdown. Actual guarantee obligations under Assistance Listing 10.438 have climbed toward that ceiling: $185.6 million in FY2018, $160.4 million in FY2019, $230.0 million in FY2020, $230.0 million in FY2021, $250.0 million in FY2022, with FY2023 and FY2024 estimated at the full $400 million.

Fiscal year	Section 538 guarantee obligations	Program level (appropriations)
FY2018	$185.6 million	n/a
FY2019	$160.4 million	n/a
FY2020	$230.0 million	n/a
FY2021	$230.0 million	n/a
FY2022	$250.0 million	n/a
FY2023	$400 million (est.)	$400 million
FY2024	$400 million (est.)	$400 million
FY2025	n/a	$400 million
FY2026	n/a	$400 million

Sources: SAMAssistance Listing 10.438 (obligations, FY2023 and FY2024 marked as estimates by the agency); Housing Assistance Council appropriations table, updated December 2, 2025. The scale deserves a plain sentence. At $400 million a year, and at a rural development cost that puts most new 538 loans in the range of $100,000 to $175,000 per unit by Loan Analytics' reading of recent transactions, the program guarantees on the order of 2,300 to 4,000 new or rehabilitated apartments a year across the entire country. It is a real route, and it is a narrow one. Where the money has actually gone by state is the subject of the next table.

What else is still open in rural rental housing

The Section 538 guarantee is now the main federal channel for building rural apartments, because its older direct-loan siblings have become preservation programs.

Section 515, the direct 1 percent rural rental housing loan that built much of the existing rural apartment stock, was funded at $50 million for FY2026, down from $60 million in FY2024 and FY2025 and $70 million in FY2023. That budget is consumed by rehabilitation and preservation of an aging portfolio; Section 521 Rental Assistance, which pays the gap between tenant rent and operating cost across nearly 400,000 units, was funded at $1.715 billion, and Congress again allowed USDA to "decouple" up to 5,000 units of that assistance from Section 515 mortgages that have matured or been paid off. The Multifamily Preservation and Revitalization demonstration received $30 million. None of that builds a new building. Sections 514 and 516, the farm labor housing loan and grant programs, remain the one direct rural multifamily channel that still funds new construction, at $15 million in loans and $6 million in grants for FY2026, and only for housing occupied by domestic farm laborers. For a for-profit developer of workforce apartments in a rural county, then, the federal map has one road with a guarantee on it. Everything else is conventional.

How the SBA and 538 compare with the programs built for apartments

The final confusion in the search results is one of category. The SBA is being compared with programs that were designed for rental apartments, and it is not one of them. The table below puts the programs side by side. Figures are the published program parameters as of September 2026; every loan is priced and sized individually.

Program	Asset	Max leverage	Term	Insurance or guarantee cost	Recourse	Size limits
SBA 7(a)	Owner-occupied business real estate; no rental apartments	Set by occupancy rule and 1.15 DSCR, not an LTV cap	Up to 25 years for real estate	SBA guaranty fee	Full recourse; guarantees from all 20%+ owners	$5 million gross loan
SBA 504	Owner-occupied fixed assets; no rental apartments	90% of project cost (85% for special purpose or new business; 80% where both apply)	10, 20 or 25-year debenture	CDC and SBA fees in the debenture	Recourse; personal guarantees	$5 million debenture ($5.5 million manufacturing and energy)
USDA Section 538	Rural rental apartments, 115% AMI tenants	90% of cost or value (97% nonprofit)	25 to 40 years, fixed	0.60% to 0.65% initial, 0.25% to 0.35% annual	Lender's terms; 90% USDA guarantee	Five-unit minimum; per-unit caps at section 207(c) limits
HUD 221(d)(4)	New construction and substantial rehab, any market	87% of cost market-rate; 90% affordable and Middle Income (Mortgagee Letters 2025-02, 2025-03)	40 years fully amortizing plus construction period	MIP 0.25% at closing and annually, all programs, since Oct. 1, 2025	Non-recourse	Statutory per-unit limits; typical minimum around $4 to $5 million
HUD 223(f)	Acquisition or refinance of stabilized apartments	85% LTV market-rate	35 years fully amortizing	MIP 0.25%	Non-recourse	Statutory per-unit limits
Fannie Mae Small Loan	Stabilized apartments, 5+ units	80% LTV; 1.25x DSCR	Fixed terms up to 30 years	Agency pricing	Non-recourse with carve-outs	Up to $9 million
Freddie Mac Optigo SBL	Stabilized apartments, 5+ units	80% LTV in top markets, lower in small markets	5 to 20-year terms, 30-year amortization	Agency pricing	Non-recourse with carve-outs	$1 million to $7.5 million

Sources: 13 CFR 120.110, 120.131, 120.910; SBA SOP 50 10 8; 7 CFR 3565; USDA RD fee schedule; HUD Mortgagee Letters 2025-02 and 2025-03; Federal Register, September 23, 2025 (90 FR 45789); agency program pages and lender term sheets. Read across the rows and the pattern is clear. The apartment programs are non-recourse, leverage against value or cost, and carry an insurance or guarantee premium. The SBA programs are recourse, leverage against the borrower's own occupancy, and do not admit the asset at all. Since October 1, 2025, HUD has also removed the cost argument that once pushed small developers toward anything else: the mortgage insurance premium on every FHA multifamily program is now a flat 0.25 percent, the statutory minimum, down from a schedule that ran as high as 0.65 percent for market-rate deals.

Three questions that sort the deal

For a sponsor standing in front of a rural or small-town apartment site, the analysis reduces to three questions, in order.

Is there an operating business that will occupy at least 51 percent of the building, and can that business cover 1.15x debt service without the tenants' rent? If yes, SBA financing is available for the business, and the residential units ride along. If no, the SBA is not a lender to this project, under either program, and no structure of entities changes that.

Is the site in a USDA-eligible rural area, and will the units rent at or below 30 percent of 115 percent of AMI to households at or below 115 percent of AMI? If yes, Section 538 offers a 90 percent guarantee, 40-year fixed-rate money, and a first-come funding queue that is currently open, provided the market study can show comparable properties under the 15 percent vacancy line.

Is the project larger, urban, or unrestricted? Then it belongs with HUD 221(d)(4) or 223(f), or with an agency small-balance execution, where the leverage, the term and the non-recourse structure were written for exactly this asset.

The reason the "SBA loan for apartment building" query keeps producing wrong answers is that the SBA's real estate programs look, from a distance, like cheap high-leverage mortgages. Up close they are business loans that happen to be secured by buildings. The apartment developer's problem is not that the SBA says no. It is that half the internet has not read the sentence in which it says so.

Frequently asked questions

Can I use an SBA 7(a) or 504 loan to buy an apartment building?

No. 13 CFR 120.110(c) excludes passive businesses owned by developers and landlords, and SBA SOP 50 10 8 states directly that "apartment buildings and mobile home parks are not eligible." The bar applies to both programs and to every loan purpose, including a building the landlord would use for its own office.

What about a mixed-use building with apartments upstairs?

Eligible only as a loan to the operating business downstairs. That business must occupy at least 51 percent of an existing building, or 60 percent of a new one with no more than 20 percent permanently leased. The rental income from the apartments is excluded from the repayment analysis, so the business must cover 1.15x debt service on its own.

Does forming an LLC to hold the real estate get around the rule?

No. The Eligible Passive Company structure under 13 CFR 120.111 lets a holding entity own the property, but only if it leases it to the borrower's own operating company, which must be a co-borrower or guarantor. An EPC that leases to residential tenants is simply a landlord, and landlords are ineligible.

Which residential-type businesses can get SBA loans?

Hotels, motels, RV parks, marinas and campgrounds that earn more than 50 percent of revenue from guests staying 30 days or less; licensed assisted living, memory care and nursing facilities; and short-term rental operations run as transient lodging in compliance with zoning and HOA rules. Independent living without services and mobile home parks are ineligible.

What is USDA Section 538 and who qualifies?

A USDA Rural Development guarantee of up to 90 percent on private lender loans for rural rental housing of five or more units. Tenants must be at or below 115 percent of area median income at move-in, rents are capped at 30 percent of 115 percent of AMI, terms run 25 to 40 years at a fixed rate, and for-profit borrowers may finance up to 90 percent of cost. The program level is $400 million a year and applications are accepted continuously.

How much does a Section 538 guarantee cost?

An initial fee of 0.65 percent of the guaranteed amount (0.60 percent for workforce, preservation or green projects), an annual fee of 0.35 percent of outstanding principal (0.25 percent for the same categories), and a $2,500 application fee, under the schedule effective April 4, 2022.
