Self Storage Feasibility Study: Demand, Supply, Lease-Up and Financing

A self storage feasibility study tells a lender whether one proposed, expanded or acquired storage facility, on one specific site, can rent enough space at supportable rates to pay its operating costs and its debt at the coverage the capital source requires. It must answer for the lease-up months as well as the stabilized years, because a new store opens empty and its debt service starts long before it is full. The answer rests on a counted supply of competing space, a demand estimate built from the trade area, a monthly lease-up model and a coverage test, each tied to dated evidence.

Four facts frame almost every storage loan file:

• The industry is large and made of small operators. The 2022 Economic Census counted 18,465 self-storage establishments with $20.6 billion of receipts [1], and in 2023, 91.4% of establishments had fewer than five employees [2].
• New construction peaked in 2023. Private spending on mini-storage construction reached $7,836 million in 2023 and fell to $6,359 million in 2025 [3].
• Renters move about three times as often as owners. In 2025, 21.1% of people in renter households had moved in the past year, against 6.3% of people in owner households [4].
• Program rules decide the structure. SBA may require a feasibility study [5], SBA's 504 procedures name market saturation as a reason to ask for one [6], and USDA requires one for a Business and Industry guarantee above $1,000,000 to a new business [7].

This page sets out what the study must prove, the federal data it draws on, how state lien laws and federal programs change the numbers, and how each capital source reads the result. For state detail, see the state pages, such as the Florida self storage feasibility study and the Texas self storage feasibility study. For boats, trailers and RVs, see the boat and RV storage feasibility study.

Every study ends in one of three conclusions: feasible as proposed; feasible with stated conditions, such as a larger lease-up reserve, a phased build or a different unit mix; or not feasible as proposed, with the changes that would make it work.

What is a self storage feasibility study?

It is an independent analysis, written for the lender's file, of whether a storage project can support its financing. USDA's rule describes a feasibility study as a report by an independent qualified consultant "evaluating the economic, market, technical, financial, and management feasibility of the proposed project" [7]. Those five parts make a sound outline for any capital source, and a study built to them also answers the narrower questions a bank or SBA lender asks.

In federal statistics the business is NAICS 531130, lessors of miniwarehouses and self-storage units. Census describes these establishments as providing secure space, "rooms, compartments, lockers, containers, or outdoor space," where clients store and retrieve their goods [8]. That one code covers a single-story drive-up site on a highway frontage, a multistory climate-controlled building beside apartments, and a gravel lot rented to boat and RV owners. The 2010 ADA Standards define a self-service storage facility as one "designed and used for the purpose of renting or leasing individual storage spaces to customers" who store and remove their own property [9]. So the study begins by defining the product: rentable square feet, unit count, unit mix, the climate-controlled and drive-up split, vehicle spaces, phasing and the opening date.

A feasibility study is not an appraisal. An appraisal estimates value at a date. A feasibility study tests whether the project works and what would have to change if it does not. SBA requires a real estate appraisal on a 504 project when the estimated value of the project property is greater than $500,000 [6], so lenders often order both. A feasibility study is also not a market report sold to many readers. It answers one lender's questions about one site and one loan.

Related scopes can come before it or run beside it. A sponsor still choosing between parcels may need a site comparison. A parcel whose use is unsettled may need a highest and best use analysis that tests storage against housing, retail or industrial uses. A lender needs an appraisal for collateral. The feasibility study takes the chosen site and program as given and tests whether they work.

What does a lender need the study to prove?

A lender needs proof that the store's own cash flow will repay the loan under the program's rules, and that nothing about the site, the operator or the structure breaks those rules. SBA's regulation states the standard plainly: "Loans must be so sound as to reasonably assure repayment" [5].

Exhibit 1. What the lender asks and what the study shows

Source: 13 CFR Part 120; SBA SOP 50 10 8.1; 7 CFR Part 5001; U.S. EPA; 44 CFR 60.3; 2010 ADA Standards, as cited in each row.

SBA does not require a study on every loan. Its regulation lets SBA require "a feasibility study" among other loan conditions [5], and the 504 chapter of SOP 50 10 8.1 lists the conditions that may lead SBA to request one: market saturation by industry type and location, a unique market concept, a highly specialized project property, a project size disproportionate to the community it will serve, and rapid growth of the applicant with unseasoned debt [6]. Storage files often raise the first of these, because new supply can be added quickly and an existing operator can expand on land it already owns.

USDA is stricter. For a Business and Industry guarantee greater than $1,000,000 to a new business, "a feasibility study prepared by an independent qualified consultant acceptable to the Agency is required," and the Agency sets its scope [7]. For loans of $1,000,000 or less, the Agency may still require one when the lender's analysis is not sufficient to show viability [7]. For what separates a study a lender can rely on from one it cannot, see what makes a feasibility study bankable.

Banks, life companies, conduit lenders and debt funds set their own coverage, leverage and reserve tests by credit policy. They read the same study for stabilized occupancy, achieved rent, expense load and the lease-up path to a take-out. The study reports coverage at whatever threshold the lender names and states the occupancy at which coverage falls below it, so a credit officer can compare the margin with the lender's own tolerance.

How large is the self-storage industry in federal data?

It is a $20.6 billion employer industry of about 18,500 establishments, most of them run by a handful of people. The 2022 Economic Census counted 8,946 firms operating 18,465 establishments in NAICS 531130, with receipts of $20,615,435 thousand and 47,642 paid employees [1]. County Business Patterns counted 18,564 establishments and 48,382 employees in 2023 [2].

The size standard matters for SBA eligibility. A storage business qualifies as small when its annual receipts, measured under SBA's rules, fall within $34.0 million [12]. With average receipts of about $1.1 million per establishment in 2022 [1], most independent operators sit far below that line; the question for a large sponsor is whether affiliates push it over.

Receipts are concentrated in large, fast-growing states. California, Texas and Florida together produced 38.5% of national receipts in 2022, and the ten states in Exhibit 3 produced 62.6% [1].

Receipts per establishment range from $1,574 thousand in California to $966 thousand in Georgia among these ten states [1]. The spread reflects rent levels, facility size and the mix of urban and rural stores. It is a reminder that a national average rent, size or revenue figure is not a local benchmark: the study prices the subject from its own trade area.

Two points follow for a lender. First, a storage facility is a thinly staffed business, so management depth sits in systems, in the sponsor and in any third-party manager, and the study assesses all three. Second, wages are a small part of the budget: payroll equaled 8.1% of receipts in 2022 [1], so the operating budget is driven by property tax, insurance, marketing, utilities, repairs and management fees (Exhibit 15).

How much new self-storage is being built?

Less than at the 2023 peak. Census estimates private construction spending in a mini-storage category that "includes mini-storage centers and self storage centers" [13]. Spending reached $7,836 million in 2023 and fell to $6,359 million in 2025, a decline of 18.8% [3]. It was $963 million in 2015 [14], so the 2025 level is still 6.6 times the 2015 level.

The series shows two waves. Annual spending rose from $963 million in 2015 to $4,893 million in 2018, eased through 2021, then climbed to the 2023 peak [14][3]. The figures are in current dollars, so part of the second wave is construction cost inflation rather than more space. Census reports a coefficient of variation of 5% for the annual mini-storage estimate [3]: precise enough to read the trend, not precise enough to treat a small year-to-year change as meaningful.

Exhibit 6. Mini-storage construction, seasonally adjusted annual rate, September 2024 to September 2026

Source: U.S. Census Bureau, Value of Private Construction Put in Place, Seasonally Adjusted Annual Rate, release covering September 2026 [15]. The September 2026 value is preliminary.

The September 2026 preliminary rate of $6,244 million was 2.3% below September 2025 and 15.8% below September 2024 [15]. Spending has settled near the 2025 level rather than falling further.

National spending tells a lender the direction of new supply, not the supply in one trade area. Construction put in place measures work underway now, and a store under construction this month usually opens while a subject project started at the same time is still leasing up. So the study counts local projects one at a time: building permits, site plan approvals, planning commission agendas, operator announcements, visible site work and unused land at existing stores. Each project gets a status (proposed, approved, permitted, under construction or open) and a probable opening month, and the model places those openings on the same timeline as the subject's lease-up so demand is not counted twice. An approved plan that has not moved in years is reported but not counted in full; a building with its roof on is.

Incumbent expansion deserves its own line. An existing operator can add a building on reserved land, fit out shell space or convert open land to vehicle spaces with far less notice than a new project. The supply survey records remaining land and prior approvals at each competitor, because expansion is often the fastest response to a new entrant.

Competitive response is the other half of the pipeline question. Operators with low occupancy may cut street rates or offer free months to protect cash flow; strong operators may answer a new store with promotions on the unit sizes where the two overlap. A rate response rarely touches every unit. The model identifies the sizes and products where the subject meets its nearest competitors, and it tests lease-up with those rates held flat or reduced rather than assuming today's quotes hold for two years.

Where does self-storage demand come from?

Demand comes from events that separate people from space: moves, smaller homes, household changes and business needs. The study measures those drivers inside the trade area, then converts them into rentable square feet by product.

Renters move far more often than owners. In the 2025 American Community Survey, 21,724,513 people in renter households had moved within the past year, 21.1% of the renter-household population, against 14,236,097 people in owner households, or 6.3% [4][16]. Renters made up 31.2% of the household population but 60.4% of movers. More than half of all movers, 53.0%, stayed within the same county [4], which is why local trade areas, not metro averages, carry the forecast.

Housing type matters as much as tenure. Of 46,551,688 renter households in 2025, 22,584,884, or 48.5%, lived in buildings with five or more units, and 8,184,211, or 17.6%, in buildings with 50 or more [18]. Among owners, only 3.5% lived in buildings of five or more units [18]. Apartment households have little closet, attic or garage space, so a trade area with many renters in large buildings supports more small climate-controlled units than a suburb of detached owner homes.

New single-family homes shape demand through garages, lots and association rules. Of 1,005,000 new single-family homes completed in 2025 [19], 9% had no garage or carport and 10% had a one-car garage, while the share with a garage for three or more cars fell to 15% from 19% in 2021 [20]. The median lot of a new home sold in 2025 was 8,307 square feet [21], and 64% of new single-family homes completed were in a homeowners' association [22], up from 46% in 2009 [22]. Association rules can restrict what owners keep in driveways, which can push trailers, boats and RVs, and sometimes household overflow, to off-site storage.

Other drivers are tested locally, without national ratios: household formation and divorce, deaths and estate settlement, downsizing by older owners, renovation, seasonal residents, students, military relocations near installations, and small businesses that use storage as inventory or equipment space. Each is checked against the site's access and design. A contractor needs drive-up units, wide doors and early access hours, and will not rent a third-floor interior locker.

A common demand method multiplies households by a usage rate and an average rented area. No federal agency publishes a storage usage rate, so the study does not import a national rate as fact. It calibrates usage to the trade area itself: occupied square feet at existing stores, from the supply survey, divided by households within reach gives an observed local rate, which is then adjusted for renter share, housing type and growth. Demand calibrated this way rests on evidence a lender can check.

How is the trade area defined?

By drive time and by how people actually travel, not by a fixed radius. The study draws primary and secondary trade areas from the road network, tests them at several drive times, and then adjusts for rivers, rail lines, limited crossings, divided highways without median breaks, and the routes residents take to work and shopping. A site on the inbound side of a commuter arterial draws differently from one on the outbound side, and a store behind a difficult left turn loses customers it would win on paper.

Competing stores shape the boundary as well. A customer rarely drives past two stores to reach a third, so each competitor's location trims the subject's practical reach. The study maps competitors first, then draws the subject's likely draw area, then measures households, renters and growth inside it.

The primary trade area carries the forecast. A secondary area may add occasional customers, such as businesses or vehicle owners willing to drive farther, but the base case does not depend on it. Census data (population estimates, the American Community Survey and building permits) are pulled for the block groups or tracts inside the drawn area, not for the county, and new apartments under construction inside the area are added to the household base when they are due to open.

How do you measure supply and saturation?

By counting every competing store's rentable space, product and pipeline inside the trade area, then comparing supply with households and with occupancy. No federal agency publishes rentable square feet of self-storage by place, so the study builds its own inventory. Census counts establishments, not square feet: in 2023 there were 18,564 storage establishments, about 5.5 per 100,000 residents, or one for every 18,140 residents [2][23].

Exhibit 10. Storage establishments and renter share in states with FSC state pages

Source: U.S. Census Bureau, County Business Patterns 2023, cbp23st and cbp23us, NAICS 531130 [24][2]; Census population estimates for July 1, 2023 [23]; American Community Survey 2025 1-year, Table B25003 [17]. Ratios and shares calculated by FSC.

New Mexico and Nevada had about 8.9 storage establishments per 100,000 residents in 2023, against 2.4 in Wisconsin and 3.1 in Michigan [24][23]. That is a count of businesses, not of space. One establishment can be a small rural lot or a large multistory building, so the ratio cannot say by itself that a state is over or under supplied. It does show why a national ratio is not a local test.

Square feet per person is a useful first screen, because it puts local supply against the resident base on one scale. It is not a demand forecast, and no federal agency publishes a saturation threshold. The same ratio can describe a renter-heavy district of small apartments, a suburb of owners with garages, or a resort town where part-year residents rent space. It can also hide product gaps: plentiful drive-up space does not satisfy demand for climate-controlled units, and a vehicle lot does not answer household demand. The study reports the ratio by product type, with existing and credible pipeline supply both shown, and reads it beside occupancy and rate evidence.

The inventory itself uses several independent sources, because no single list is complete:

• business license and tax registration records, and state corporate filings, which catch operators that do not advertise widely;
• county assessor records for building area and year built;
• planning and building permit records for new projects and expansions;
• aerial imagery, read for building footprints, outdoor vehicle spaces and cleared land;
• operator websites for unit sizes, rates and availability by size;
• site visits and calls for access, condition, security, hours, gate technology and visible vacancy.

Contractor yards, warehouse space and moving-company storage are not counted as direct substitutes unless they rent to the public on similar terms. Two names at one address are reconciled to one store.

Saturation testing then runs several cases: a base case with existing supply, credible pipeline and the subject; a smaller effective trade area; slower household growth; a competitor expansion; and weaker capture of specific unit sizes. The question is not whether one ratio passes. It is whether the project remains supportable when several reasonable disadvantages occur together.

How should the study read occupancy, rents and achieved revenue?

Separately for each measure, because "occupancy" and "rent" each have several meanings and a file that mixes them overstates revenue. Physical occupancy measures rented area against rentable area. Unit occupancy measures rented units against all units, and it can sit above or below physical occupancy depending on which sizes are empty. Economic occupancy measures rent collected against the rent the rate schedule would produce, so it captures discounts, free months, delinquency and bad debt.

Exhibit 11. Occupancy and rent measures the study keeps separate

Source: FSC study method; definitions as used on this page. The table contains no market figures.

A store's advertised price is the street rate offered to a new customer, often online and often with a first-month discount. Tenants in place pay the rate set when they moved in plus later increases. A store can therefore look nearly full while producing weak economic occupancy, if long-term tenants pay well below current asking rates or if move-in promotions have become permanent. The survey records each quote with its date, channel (web, phone or walk-in), unit size, climate control, administrative fee, any insurance or protection requirement and any concession. A headline web rate without its conditions is not a revenue comparable.

Increases to tenants in place can be a material part of storage revenue, and state law can shape them. California's storage statute, as summarized in a 2025 Senate Judiciary Committee analysis, requires 30 days' notice to amend a rental agreement, such as a rent increase, and does not limit how much or how often rent may rise [25]. A separate 2025 California bill proposed limiting increases to "five percent plus the percentage change in the cost of living, or ten percent, whichever is lower" [26]. Where such proposals are active, the study treats rate growth on existing tenants as a regulatory risk and tests a case without it.

Occupancy evidence is read in context. A competitor reporting few vacancies may be full, may be holding units out of service during repairs, or may be quoting scarcity to close a rental. Repeated observations over several weeks, online availability by size, manager interviews and changes in advertised offers separate a stable pattern from a single answer. For an acquisition, the store's own rent roll and monthly move-in and move-out history replace most of that inference with records.

How do unit mix and climate control change the forecast?

They decide which customers the store can serve and how fast its space rents. Unit mix links the market analysis to the site plan. Small units widen the customer pool and rent for more per square foot, but they add doors, partitions and management time. Large units bring large monthly rents but concentrate vacancy, because a few empty 10x30 spaces leave a lot of area idle. The model tracks units and square feet together so a healthy unit count does not disguise empty large bays.

Climate control depends on local weather, the value of stored goods, apartment living and the customer's willingness to trade drive-up access for interior protection. Drive-up space suits frequent access, household moves, contractors and bulky goods. The split comes from competitor availability by product and the local customer profile, not from what new facilities built in other markets. A multistory building adds elevators, corridors and a loading area, which change how otherwise identical unit sizes rent.

Accessible units are part of the mix. The 2010 ADA Standards require a minimum number of accessible storage spaces: 5% of spaces, but no fewer than 1, in facilities with 1 to 200 spaces, and for facilities with 201 and over, "10, plus 2 percent of total number of units over 200" [9]. Accessible spaces must be dispersed throughout the classes of spaces provided, but they need not be spread among buildings in a multi-building facility [9]. Where a percentage produces a fraction, the next greater whole number is provided [9].

Source: U.S. Department of Justice, 2010 ADA Standards for Accessible Design, Table 225.3 and section 104.2 [9]. Counts calculated by FSC, rounding fractions up.

The site plan therefore reserves accessible units in each class, near an accessible route and accessible parking. The effect on revenue is small, but a missing allocation is a common plan-review comment and a late redesign costs time.

How do state lien laws affect collections and bad debt?

They set the clock between a missed payment and the sale that clears the unit, and that clock sets the bad-debt and turnover assumptions. Every state in Exhibit 13 gives the operator a lien on stored property, and most let the operator enforce it by notice and sale rather than a lawsuit, but default periods, notice methods, advertising and vehicle rules differ. Texas is the clearest exception: a lessor may enforce the lien without a court judgment only when the rental agreement states a contractual landlord's lien underlined or in conspicuous bold print [27]. A longer timeline keeps a delinquent unit off the market for more months before it can be emptied and re-rented.

Exhibit 13. Self-storage lien enforcement in sixteen states: key timing rules

Source: state statutes and session laws as cited in each row. California from a 2025 Senate Judiciary Committee analysis of the act [25]; New Mexico from existing law reproduced in a 2025 bill that did not pass [41].

Read across the table, the gap is wide. Mississippi allows enforcement after 14 days of continuous default [37], while New Mexico's existing law bars any action to sell until 90 days of continuous default [41]. A store in the second state carries delinquent units for months longer, and the model reflects that with a larger delinquency allowance and a longer re-rent cycle.

Notice rules have also changed. Several states now accept email with a fallback: Georgia requires verified mail if an emailed notice draws no nonautomated response or delivery receipt [33], and New York treats email as effective only when the occupant has given an email address in at least two places in the agreement [42]. Online auctions are allowed in Illinois [34], New Jersey [40] and Georgia [33]. These rules cut the cost and time of a lien sale, which matters to the expense budget as well as to bad debt.

The study models collections from the statute that governs the site: a delinquency allowance, the months from default to sale, the cost of notices, advertising and auction, and a vacancy period before the unit is re-rented. Two operating rules also enter the file. Florida bars using any storage space for residential purposes [32], which the management plan must enforce. And Florida repealed its state sales tax on commercial rentals effective October 1, 2025, listing self-storage units among the rentals covered [43], while tax continues on parking or storage spaces for motor vehicles and on boat docking or storage [43]. A Florida store with both enclosed units and vehicle spaces therefore carries two tax treatments.

How long does lease-up take, and how large should the reserve be?

Long enough that the reserve, rather than stabilized coverage, often decides the loan. A new store opens empty and fills over months or years. Until it reaches break-even occupancy, revenue falls short of operating costs plus debt service, and the gap has to be funded in advance. No federal agency publishes lease-up periods for storage, so the study builds the curve from local evidence: competitor openings and their occupancy over time, availability by size, the seasonality of moves, and the subject's visibility, access and pre-opening marketing.

The curve is monthly, not a straight line. Early rentals may come quickly from pre-opening marketing and opening promotions, followed by slower months while the store earns reviews and visibility. Gross move-ins are not net absorption: move-outs start in the first months, so the model carries churn forward. Climate-controlled, drive-up and vehicle spaces get separate curves when their customer pools differ. Stabilization is not only an occupancy target. It also requires recurring achieved revenue after opening discounts end.

SBA's rules frame the test. For a Standard 7(a) start-up or other application based on projections, SOP 50 10 8.1 requires projections that reflect coverage of at least 1.15 within 2 years from loan funding or, for construction projects, within 2 years from the end of construction [6]. For a 504 project, if projections show repayment in Year 2 but not in Year 1, the borrower must show enough liquidity to cover the Year 1 shortfall [6]. Both rules put the reserve at the center of a ground-up storage file.

The lease-up reserve check below screens one question: how much cash it takes to carry full debt service until occupancy reaches break-even, first on the sponsor's projected lease-up and then on a slower 36-month lease-up. It takes four inputs: projected months to stabilized occupancy, stabilized occupancy, break-even occupancy and monthly debt service. It assumes a straight-line ramp from opening, so months to break-even equal the lease-up months multiplied by break-even occupancy and divided by stabilized occupancy, and it carries full debt service until break-even. Its default inputs are illustrative, not market data, and the 36-month comparison is a stress case built into the tool, not a market benchmark. The result is a screen, not a feasibility conclusion.

Exhibit 14. Illustrative reserve sizing using the calculator's method

Source: FSC model output. Illustrative inputs, not market data: stabilized occupancy 88%, monthly debt service $40,000, break-even occupancy 60% or 70%.

Two patterns stand out. Doubling the lease-up period doubles the reserve, and raising break-even occupancy from 60% to 70% adds 16.7% to it. The full model adds what the screen leaves out: operating deficits before revenue covers expenses, interest during construction, seasonal move-in patterns, the timing of property tax and insurance bills, and the effect of opening discounts on collected rent. It reports the month in which operating cash flow first covers debt service and the month in which coverage clears the lender's floor, and it sizes the interest and lease-up reserves to the slower case.

What does it cost to build and operate a self-storage facility?

Costs come from the project's own budget, bids and quotes, checked against federal ratios; no national cost per square foot is used as fact. The development budget is reconciled to sources and uses: land, site work, utilities, stormwater, buildings, climate systems, elevators, security, office, signage, professional and permit fees, financing costs, interest during construction, contingency, pre-opening marketing and the lease-up reserve. Each cost is placed in the month it is paid rather than on opening day. Where phasing is possible, the model tests whether later buildings can wait without hurting circulation or the first phase.

Land the sponsor contributes is valued by rule on an SBA 504 project. It is valued at cost if it was purchased less than 2 years before the application, and at fair market value from an independent appraisal if it has been held 2 years or more [6]. A sponsor who bought land last year cannot count its appreciation as equity.

Operating expenses are built line by line: payroll for the staffing plan, management (owner, third-party or remote), property tax, insurance, utilities, repairs, security monitoring, software, marketing, card fees, professional fees, landscaping, snow removal, pest control and replacement reserves. Census ratios then test whether the result is plausible.

Exhibit 15. Operating ratios for self-storage from Census data

Source: calculated by FSC from U.S. Census Bureau, 2022 Economic Census (EC2253BASIC) [1] and County Business Patterns 2023 (cbp23us) [2], NAICS 531130. Values rounded.

These ratios describe an average that mixes large portfolios with single stores, so they test a budget rather than replace it. A staffing plan that puts payroll far above 8.1% of revenue at stabilization needs a reason, such as extended office hours or a retail counter. A plan with no on-site staff needs a remote-management system the lender can see.

Property tax is projected on the assessment that the purchase price or completed value will trigger, not on the seller's current bill. Buyers sometimes allocate part of a storage purchase price to goodwill to reduce the taxable real property value. In a 2007 decision, the Supreme Court of Ohio affirmed a tax board's refusal to subtract a $950,000 goodwill allocation from a $1,950,000 self-storage purchase price, holding that "the proponent of an allocation of sale price bears an initial burden of showing the propriety of the allocation" [44]. The property in that case held 352 non-climate-controlled units and 63 outside spaces [44]. The study therefore models taxes on the full price unless local law and evidence support a split, and it keeps any business value analysis separate from the real estate.

Insurance is quoted at current rates rather than inflated from an old policy, with wind and flood deductibles stated for coastal sites. The Hillsborough County model study shows how property tax, windstorm cover and deductibles narrow a Gulf Coast store's margin.

How do interest rates change coverage?

Directly, because a storage loan carries a large fixed payment against revenue that builds slowly. On November 9, 2026, the bank prime loan rate was 7.00% and the 10-year Treasury constant maturity yield was 4.88% [45]. Under SOP 50 10 8.1, the variable rate on a Standard 7(a) loan of $350,001 and greater "cannot exceed Prime or SBA Optional Peg Rate + 3.0%" [6], which at that prime rate means 10.00%.

Exhibit 17. Illustrative interest-rate stress on a $5,000,000 storage loan

Source: FSC model output. Illustrative assumptions, not market data: $5,000,000 loan, 25-year amortization with monthly payments, potential revenue of $1,250,000 at full economic occupancy, operating expenses of $437,500 held fixed. Rate points from the Federal Reserve H.15 release [45] and the SOP 50 10 8.1 cap [6]; not a loan quote.

In this example, each added point of interest raises break-even occupancy by about 3 to 3.5 points, and at 10.00% the store needs 85.2% economic occupancy to reach 1.15 coverage. The study runs the lender's actual terms, including any interest-only period, and reports the occupancy at which coverage falls below the floor. It also runs a rate shock on variable-rate debt, since a store that clears coverage at today's rate can fail it after a reset.

Equity investors look at other measures: internal rate of return and net present value, using capital contributions, operating cash flow, a sale assumption and transaction costs. The study can report them, but they supplement the lender's coverage test and never replace it.

Which financing paths fit a self-storage project?

SBA 7(a) and 504 fit owner-operators, USDA Business and Industry fits rural projects in which the owner controls tenants and services, and banks, conduit lenders and debt funds serve larger and stabilized stores on their own terms.

Exhibit 18. Federal financing programs compared for self-storage

Source: 13 CFR Part 120 (revised as of January 1, 2026); SBA SOP 50 10 8.1; SBA 504 loans page; 7 CFR Part 5001 (revised as of January 1, 2026); USDA FY 2026 OneRD notice, 91 FR 11272. USDA resets guarantee percentages each fiscal year; confirm with the State Office.

The 504 job rule needs care. A project "must create or retain one job opportunity per $95,000 guaranteed by SBA" unless it qualifies under another objective [6]. A store employs few people, about 2.6 per establishment nationally [1], so CDCs often rely on a community development or public policy goal, in which case the CDC's portfolio must average one job opportunity for every $150,000 guaranteed [6]. If no objective is met, the debenture must be reduced [6]. The study supplies the job count and the facts behind any other objective.

Banks, life companies, conduit lenders and debt funds set coverage, leverage, reserves and recourse by policy. Construction lenders focus on the lease-up and the take-out; conduit lenders focus on stabilized achieved rent and expense load; debt funds focus on the path from opening to a refinance. One study serves all of them when it reports results at each lender's named threshold and shows the downside cases.

Is self-storage eligible for SBA and USDA financing?

Usually yes, when the borrower operates the store, but the file has to show it. SBA bars passive businesses owned by developers and landlords that do not actively use the assets financed [5], and businesses "primarily engaged in owning or purchasing real estate and leasing it for any purpose" [6]. At the same time, SOP 50 10 8.1 treats businesses "engaged in leasing equipment, household goods or other items" as eligible [6], and its change-of-ownership rules give storage units as an example of an acquisition in which the property is integral to the operating business [6]. A storage operator that sets rents, rents units to the public, controls access, collects and sells services runs a business; the lender documents that.

Exhibit 19. Eligibility tests a storage file must pass

Source: 13 CFR Part 120; SBA SOP 50 10 8.1; 7 CFR Part 5001, as cited in each row.

SBA's occupancy rule for financed buildings asks the applicant to occupy 51% of an existing building or 60% of new construction [5]. That rule is written for a business that leases part of its building to other businesses, and the SOP lets Rentable Property include exterior space actively used in operations [6]. How it applies to a store renting units to the public is a classification question for the lender and CDC; the study describes operations in enough detail for them to decide.

USDA's rule does not name self-storage as eligible or ineligible. The test that matters is control: an owner that sets rents, screens tenants, controls access and sells services has control over tenants and services, while a passive land lease or master-leased facility does not [7].

How are acquisitions of existing stores tested?

On history first. For a 7(a) change of ownership, SOP 50 10 8.1 requires debt service coverage of 1.25:1 for an initial acquisition and 1.15:1 for a business expansion, using the last fiscal year-end or the average of the last two [6]. The equity injection for an initial acquisition is 10% [6].

Storage has a specific provision. When the purchase of an owner-occupied Special Purpose Property cannot be separated from the operating business, and the appraised value fully collateralizes the loan, the lender may rely on projections, with the coverage requirement met within two years from loan funding. The SOP names "storage units and hotels where the real estate fully secures the loan" as examples [6]. In those transactions the loan may run up to 25 years if 85% or more of project costs are for real estate [6], a Quality of Earnings report is not required [6], and the appraiser must have completed no fewer than four going-concern appraisals of equivalent special use property within the last 36 months [6]. The lender documents why the property meets the Special Purpose Property definition [6].

Exhibit 20. Acquisition rules that apply to an existing store

Source: U.S. Small Business Administration, SOP 50 10 8.1, Appendix 15, 7(a) Changes of Ownership [6].

The study ties out the seller's history: the rent roll against the general ledger, physical against economic occupancy, delinquency and lien-sale history, street rates against rates in place, the size and timing of increases to existing tenants, and property tax reassessed at the purchase price. It tests whether historical revenue depended on rate increases a new owner can keep, and whether deferred maintenance on roofs, doors, paving and gates must be funded at closing.

What site, zoning and building issues decide feasibility?

Zoning, access, stormwater, flood exposure and accessibility can each stop a storage project or change its cost. Many codes allow storage only in some districts and attach standards. In Raleigh, North Carolina, for example, a self-storage facility in the CX district needs a site of at least 2 acres [48], and outdoor storage of boats and RVs is not permitted with self-storage in some districts [48].

Exhibit 21. Site and building thresholds that apply to storage projects

Source: City of Raleigh UDO; U.S. EPA; 44 CFR 60.3 (revised as of July 1, 2025); 2010 ADA Standards; SBA SOP 50 10 8.1; Florida Statutes, as cited in each row.

Access decides how a store performs as much as zoning decides whether it can be built. The site needs visibility from the road customers use, a safe turn in, room for a moving truck to circulate and stack at the gate, and enough aisle width for drive-up units. Vehicle storage needs much larger turning paths. Fire access, hydrants and sprinklers for larger buildings, utility capacity for climate control, and the cost of a detention pond on a small site are confirmed with the local jurisdiction and priced in the budget. Flood exposure is read from the effective flood map; a nonresidential building in a mapped flood zone must be elevated or floodproofed [11], which adds cost and can change the building plan.

How does boat and RV storage change the study?

It adds a separate demand pool, a different site plan and different lien rules. Vehicle storage demand rests on registered boats and RVs and on rules that keep them away from homes, not on household counts alone. The states registered 11,674,073 recreational vessels in 2024 [50], and RV wholesale shipments totaled 342,220 units in 2025 [51], though shipments in the first nine months of 2026 were 13.7% below the same period of 2025 [52]. Associations cover 64% of new single-family homes completed in 2025 [22], and some local codes cap vehicles at a home: Clark County, Nevada, states that storage of more than 3 recreational vehicles or travel trailers on private property is prohibited [53].

Exhibit 22. Vehicle storage demand indicators

Source: U.S. Coast Guard; Federal Highway Administration, Table MV-1; RV Industry Association; U.S. Census Bureau, Characteristics of New Housing, as cited in each row.

Most of the statutes in Exhibit 13 let an operator tow a vehicle, boat or trailer after 60 days unpaid, while Arizona allows towing after more than thirty days in default [29]. Texas requires notice to the owner and lienholders of a vehicle or vessel within 30 days after the lessor takes possession [27]. So a mixed facility models two collection paths. The full method for vehicle storage, including space modules, turning paths and registration data, is in the boat and RV storage feasibility study.

What does the Hillsborough County model study show?

That a store in a large, growing county can still fail coverage at the minimum contribution. FSC's model study of a 425-unit, 52,875-square-foot store in Hillsborough County, Florida, financed under SBA 504, found stabilized coverage of 0.89x at a 15% borrower contribution and 1.28x when restructured with a 40% contribution. Those are model outputs from illustrative inputs built on public data; the study is a worked example.

Exhibit 23. Hillsborough County model study: results as submitted and restructured

Source: FSC model study, 425-unit self-storage facility in Hillsborough County, Florida. Model outputs from illustrative inputs; not market data.

The example shows the logic of the whole page in one file. Demand was large, but the rents were assumptions a site survey must confirm, Gulf Coast insurance and tax costs were high, and at the minimum contribution the debt left almost no margin: break-even occupancy of 96.7% is not a bankable position. A larger contribution and a funded lease-up reserve turned the same store into a conditional yes. Under the ADA table, a 425-space store also needs at least 15 accessible spaces [9].

What should be tracked after the loan closes?

The same assumptions the study tested. Once the store opens, the lender and the owner can compare actual results with the model's monthly path: move-ins and move-outs by product, physical and economic occupancy, street and achieved rates, concessions, delinquency and lien sales, operating expenses against budget, the reserve balance and coverage. During construction, draws, change orders, the remaining cost to complete and the opening date matter most.

A variance report against the study's base and downside cases shows early whether a store is tracking the slower case, while there is still reserve and time to act. A lender with several storage loans also watches concentration: two loans in overlapping trade areas, or a new competitor opening inside a financed store's trade area, are portfolio risks that a single-loan review can miss. Those checks use the study as the baseline, so its assumptions must be stated clearly enough to compare.

What must a self storage feasibility study contain?

A study a lender can rely on contains, at a minimum:

1. The product: site, buildings, rentable square feet, unit count and mix, climate-controlled and drive-up split, vehicle spaces, phasing and opening date.
2. The capital source, loan request and the program tests that apply.
3. A trade area drawn from drive times and travel barriers, with the reasons for each boundary.
4. Households, renters, housing type, movers and growth inside the trade area, from current Census data.
5. A competitor inventory: every store's rentable space, unit mix, products, condition, rates by size and channel, and occupancy evidence with its source.
6. The pipeline: each proposed, approved, permitted and under-construction project and each incumbent expansion, with status and expected opening.
7. Supply per capita by product, existing and with credible pipeline, read beside occupancy and rates.
8. Demand calibrated to the trade area, and the subject's expected share by product.
9. A rate plan by unit size and product from dated quotes, with concessions and the plan for increases to tenants in place.
10. A monthly lease-up model with churn, separate curves where products differ, and a stated stabilization test.
11. An operating budget from quotes, tax projections and a staffing plan, checked against Census ratios.
12. A development budget with sources and uses, land valuation, contingency, interest during construction and reserves.
13. Collections modeled under the state lien statute, with delinquency, sale timing and costs.
14. Site findings: zoning, access, stormwater, flood zone, accessibility and environmental status.
15. Coverage by month and year at the program's threshold, with downside cases for slower lease-up, lower rates, higher expenses, a competitor opening and a rate shock.
16. For an acquisition, the historical tie-out and the coverage test on actual results.
17. A management assessment: the operator's experience, systems and any third-party agreement.
18. Every source and assumption listed, with model outputs labeled as such, and a statement of the conditions on which the conclusion rests.

How much does a self storage feasibility study cost and how long does it take?

The fee for a self-storage study falls between $5,500 and $10,000, and the work takes 3 to 6 weeks. The fee is fixed in the engagement letter before work begins and does not change with the conclusion. Where a project falls in that band depends on scope: a single-phase drive-up store is simpler than a multistory climate-controlled building with vehicle spaces, and an acquisition adds the historical tie-out. Turnaround runs from the date the document set is complete.

Documents that start a study:

• the site location, parcel and site plan;
• the building program: rentable square feet, climate-controlled, drive-up and vehicle space, and the proposed unit mix;
• the development budget, or the purchase contract;
• the proposed loan structure and capital source, and the lender, CDC or USDA State Office involved;
• for an existing store: three years of operating statements and tax returns, a current rent roll, and occupancy, delinquency, discount and lien-sale reports by month;
• the management plan or third-party management agreement;
• current zoning status and approvals;
• the sponsor's storage operating experience.

How the study runs

1. Scoping: confirm the capital source, program, loan size and the tests that apply.
2. Document intake: site plan, budget, approvals and, for an operating store, rent rolls and financial statements.
3. Field and market research: site inspection, trade-area mapping, competitor and pipeline surveys, rate quotes and demand data.
4. Model: monthly by product, with base and downside cases, coverage, reserves and collections under the state statute.
5. Review: the draft is checked against the lender's questions and revised only for new facts.
6. Final report: signed by Sarrah Allen, MAI, with written answers to the lender's follow-up questions. More about the practice is on the about page.
