SBA Mixed-Use Feasibility Study: 7(a) and 504 Under SOP 50 10 8.1

A hotel file turns on demand and a car wash file on throughput. A mixed-use file turns on arithmetic the lender can do before reading the market section: how much of the building the business occupies, and how much is leased to tenants who are not the business, including the tenants who live upstairs. SBA does not lend to landlords. Under 13 CFR 120.110(c), passive businesses owned by developers and landlords that do not actively use or occupy the assets financed are ineligible, and under 120.130(d) loan proceeds may not fund property acquired or held primarily for sale, lease or investment. A building that is mostly apartments with a storefront below is an apartment building, whoever occupies the storefront, and it is outside the program.

What is inside the program is the operating business that owns its building and leases the remainder, and the remainder may be residential. The study therefore opens with the allocation, the structure and the program test, and only then turns to the two markets the building serves. The integration method for the two uses is described on the mixed-use feasibility study page.

Under 13 CFR 120.131(b), where the loan acquires, renovates or reconstructs 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. Under 120.131(a), where the loan funds new construction, the borrower must occupy at least 60 percent on completion, may permanently lease no more than 20 percent, and must occupy some of the remaining space within three years and all of it within ten. The rule applies to both 7(a) and 504, and where an Eligible Passive Company holds the building and leases it entirely to one or more Operating Companies, the Operating Companies together must meet the same percentages.

The regulation measures occupancy on Rentable Property and says nothing about residential use. Whether the apartments above an owner-occupied storefront are counted as ordinary leased space within the 49 or 20 percent, whether residential area is treated differently from commercial area, and how stairs, corridors, shafts and a shared lobby are handled, are questions the lender and CDC answer under SOP 50 10 8.1. The study does not assume the answer. It measures the building's rentable area from plans or field measurement, states the operator's area, the residential area and the common area separately, and reports the occupancy percentage under each reading the lender might adopt, so that the file carries the figure the lender needs whichever reading governs.

The main-street building type makes the test hard to pass from the storefront alone. The one downtown Columbus, Indiana building with a published floor-by-floor split measures 4,045 square feet on the main floor, 3,743 on the second and 3,972 in the lower level, 11,760 in total. Storefront only is 34.4 percent and fails. Storefront plus lower level is 68.2 percent and passes, with the second floor free to convert to apartments. Storefront plus second floor is 66.2 percent and passes, but leaves nothing above to lease. The structure works for a restaurant, brewery or taproom that can use a basement for production, cold storage, prep and office, for a clinic that can use it for records and plant, or for an operator who takes part of an upper floor as office. It does not work for a retailer who needs only the storefront, and the study says so at the outset rather than after the market analysis.

Most operators hold the building in a separate entity, and SBA permits this through the Eligible Passive Company under 13 CFR 120.111. The study documents each condition of the structure, the lease, the rent cap, the term and the guarantees, as set out on the SBA retail feasibility study page.

In a mixed-use building the EPC also holds the residential leases. The study states the residential rent roll as EPC income separate from the Operating Company's rent, because the lender underwrites the two streams differently: the Operating Company's rent is capped by regulation and backed by the business, and the apartment rents are market income backed by the submarket.

A main-street building with a restaurant or shop below and apartments above is general-purpose collateral. It is not on SBA's special-purpose list, which names gas stations and convenience stores, car washes, service centers with pits and in-ground lifts, and medical facilities among others. The 504 borrower contribution under 13 CFR 120.910 is therefore 10 percent for an established operator, 15 percent where the operator, or the Operating Company behind an EPC, has operated two years or less, and 20 percent only where the building is also limited or single purpose, which a storefront with apartments above is not. A new restaurant entity buying and converting a main-street building sits at 15 percent. The study states the tier and the reason.

The 504 job standard requires one job created or retained per $95,000 of debenture for a standard project. A $1.2 million debenture requires thirteen jobs, which a full-service restaurant or taproom meets and a small shop with apartments above does not. Where the per-project test is not met, 13 CFR 120.862 lists the community development and public policy goals that substitute for it, and the one written for this building type is revitalizing a business district of a community with a written revitalization or redevelopment plan. The CDC's portfolio must then meet its own job average. The study names the plan, cites its adoption date and quotes the objective the project serves, because the district office will ask for exactly that.

Where the borrower is buying an operating business together with its mixed-use building, SOP 50 10 8.1 Appendix 15 governs and tests the seller's history rather than a projection, at 1.25 times for an Initial Acquisition, Owner Buyout or ESOP transaction and 1.15 times for a Business Expansion. The classification and the normalization follow the acquisition method on the SBA retail page.

Most mixed-use files are not acquisitions of a going concern, and many are conversions of upper floors that have stood vacant for years, for which the building analysis on the adaptive reuse feasibility study page applies. They are the purchase of a building whose prior use is ending and whose upper floors are vacant or underused, by an operator who will open a new business below and create apartments above. That is a startup underwritten on projections, and the study is built accordingly: the operator's projection from the concept's public benchmarks and the local wage base, the apartments from the submarket's rent evidence, and the DSCR by year on the combination.

SBA 7(a) fits the purchase of a smaller mixed-use building together with the equipment, inventory and working capital the business needs, in one loan of up to $5 million; SBA 504 fits a rehabilitation with a large construction budget, with a 25-year fixed-rate debenture where real estate is 51 percent or more of proceeds, which covers every mixed-use building. The two can be combined within the $10 million combined SBA exposure, a 504 debenture on the building alongside a 7(a) loan for kitchen equipment, brewing equipment and working capital, and the program limits and fiscal 2027 fees are set out on the SBA 504 feasibility study and SBA 7(a) feasibility study pages.

The federal historic rehabilitation tax credit of 20 percent of qualified expenditures applies where the building is a certified historic structure, which on a main street inside a National Register district most contributing buildings are. The credit is a source, not debt, and the study states its timing, the substantial rehabilitation test that qualified expenditures must exceed the greater of $5,000 or the adjusted basis, and the syndication or bridge cost if the credit is monetized before completion. State commercial credits vary and have changed: Indiana eliminated its commercial credit in 2016 and the study confirms the current state terms with the state office before carrying any state credit as a source.

The study is organized around the questions the lender, the CDC and the district office will ask.

It opens with eligibility: the rentable area measured floor by floor, the operator's and the residential and common areas stated, the occupancy percentage under each reading of SOP 50 10 8.1, the borrower structure with each EPC condition documented, the special-purpose determination with the resulting equity tier, the job count against the $95,000 standard or the named revitalization plan, and, for an acquisition of a going concern, the Appendix 15 classification and the historical DSCR before and after normalization.

It then analyzes the commercial floor on the retail feasibility study method: the downtown trade area, the published leakage and surplus analysis, the competitive set verified property by property, the traffic and pedestrian evidence, and the operator's projection from the concept's public benchmarks and the local wage base with an imputed market rent carried as a check. It analyzes the residential floors on the multifamily feasibility study method: the citywide and submarket rent from the American Community Survey, the HUD Fair Market Rent schedule, dated listings with unit size, the municipal housing study, the pipeline, and an expense build that separates the residential share of tax, insurance, utilities and management. It presents the rehabilitation or construction budget by line item with the shared systems, fire separation, egress and any elevator priced separately and benchmarked against the public record of comparable projects, escalated at the current index. It states the capital stack at the applicable tier with the historic credit as a source. It reports the DSCR at each year on the combined first-mortgage and debenture service, decomposed by floor, with the ground-floor-dark case, the residential vacancy steps and the absorption delay run.

The study concludes feasible, feasible with conditions, or not feasible, with the condition expressed in the lender's terms.

The study is prepared against a retail market with 4.3 percent national vacancy in CoStar's October 2026 national report, where little is being built because in-place rents do not cover replacement cost, and against a downtown residential market in most small and mid-sized cities where the municipal housing study calls for more units than are being delivered. The combination favors the owner-occupied mixed-use building: the commercial floor is justified by the business rather than by a rent the market does not pay, and the apartments above earn market rent in a submarket short of supply. The constraints are on the cost side. Rider Levett Bucknall's national cost index rose 4.45 percent in the year to July 2026, in-line fit-out runs $120 per square foot in the Midwest and $157 nationally in Cushman & Wakefield's 2026 guide before a restaurant's kitchen, hood and grease systems are added, and the public record of small historic mixed-use rehabilitations in the most recent round of state credit awards runs from about $1.3 million to $5.0 million in total project cost. The study escalates every pre-2026 benchmark explicitly and states the project's cost against that record.

An MMCG SBA mixed-use feasibility study runs between 100 and 140 pages and is delivered in 9 to 16 business days from engagement and receipt of the project file, with rush delivery from 5 business days. Fees begin at $4,900 for a single-building SBA 7(a) mixed-use study and range from $7,500 to $15,000 for SBA 504 studies depending on the number of components, units and scenarios. Payment is 50 percent at engagement and 50 percent at delivery. MMCG accepts no referral fees, contingent fees or financing arrangements, and revisions required by the lender, CDC or SBA are made at no additional cost under MMCG's contractual acceptance commitment.

The SBA mixed-use method is illustrated by a model engagement on Washington Street in the Columbus Historic District of Columbus, Indiana: the acquisition and rehabilitation of a two- or three-story commercial block by a restaurant and taproom operator who takes the ground floor and lower level and converts the upper floor to apartments, financed under SBA 504 at the 15 percent tier. The job standard is met by the brewpub's 28 FTE, with the city's Downtown 2030 Strategic Plan available as the written revitalization plan for a smaller user. The published floor plates on the street show why the operator must take the lower level: 34 percent from the storefront alone, 68 percent with it. At the 15 percent contribution the restructured project covers at 1.12x in Year 3; it is feasible with the federal historic credit's net proceeds applied to the first mortgage, which lifts Year 3 coverage to 1.25x, or in the alternative with a 25 percent cash contribution. The engagement is illustrative and built on public evidence only. It is published as its own page: Columbus mixed-use case study.
