What Do You Need to Start a Self Storage Facility?
You need a site of 30,000 sq ft or more, $700,000 to $1,750,000 in capital for land, building and equipment, 1.5 staff at launch, and at least $500,000 in working capital to survive an eighteen-month lease-up. Revenue Map's self-storage presets model a 300-unit facility with a $1,400,000 build-out financed by a $1,050,000 loan at 7.5% over twenty years, and occupancy ramping from 25% to 88% across five years.
Starting a self storage facility requires three large categories of investment: land and building, equipment and security, and enough cash to survive the longest lease-up of any vertical in Revenue Map's model library. Unlike a restaurant or car wash, there is almost no cost of goods: gross margin sits near 97 percent, with the only direct costs being insurance resale and replacement locks. The entire challenge is surviving the months or years between opening and reaching stabilized occupancy.
Format changes the investment by a factor of two or more. Revenue Map's industry presets range from a $700,000 portable containers operation to a $1,750,000 climate-controlled facility with 260 units at $145 to $160 per month. A conversion facility, an existing warehouse or retail space repurposed for storage, presets at $1,100,000 with 400 units at $98 to $110 per month, the lowest per-unit cost of any format.
Cost Breakdown
Self storage startup requirements and their costs
| Item | Typical range | Notes | Source |
|---|---|---|---|
| Land and building (default 300-unit) | $1,400,000 | 30,000 sq ft facility with drive-up and climate-controlled units, doors, gate, and cameras | Revenue Map model presets |
| Build-out by format | $700,000 to $1,750,000 | Portable containers $700,000, vehicle/RV $900,000, conversion $1,100,000, default $1,400,000, climate-controlled $1,750,000 | Revenue Map industry presets |
| Working capital (phase-one investment) | $500,000 | Cash to cover operating losses during an 18-month ramp from 25% to stabilized occupancy | Revenue Map model presets |
| Loan financing (default) | $1,050,000 at 7.5% over 20 years | Covers 75% of the $1,400,000 build-out; amortized over 20 years against the real estate | Revenue Map model presets |
| Monthly fixed costs at launch | About $8,400 to $9,000 | Staff $4,680 with payroll tax, utilities $700, insurance $900, admin $600, marketing $1,500; no rent on owned land | Revenue Map model presets |
| Staff (facility manager and site help) | 1.5 to 2 people; $4,680 to $6,360 per month | 1.5 staff at $2,600 each plus 20% payroll tax at launch, growing to 2 at $2,650 at maturity | Revenue Map model presets |

What Moves the Number
The lease-up dominates everything
Revenue Map's presets model an 18-month ramp starting at 25% of phase-one demand. At 300 units and $105 per month with 45% occupancy, the initial occupied count is well below break-even. The facility bleeds cash for the first year or more, and the $500,000 phase-one investment exists to cover that deficit. A facility that reaches 85% occupancy in eighteen months and one that takes thirty-six months have the same stabilized P and L and completely different outcomes.
Format sets the unit count and rate
Climate-controlled storage presets at 260 units and $145 to $160 per month with $1,750,000 capex. A conversion facility fits 400 units at $98 to $110 per month for $1,100,000. Vehicle and RV storage runs 140 units at $185 to $205 per month for $900,000. The choice between new construction, conversion, and portable containers determines the capital requirement, the revenue ceiling, and how many months of lease-up the owner must finance.
Debt service coverage is the binding test
Revenue Map's deep dive notes that DSCR is the test a lender applies to a storage project, because the asset is real-estate-backed. The default $1,050,000 loan at 7.5% over twenty years carries a monthly debt service of roughly $8,500. At stabilized occupancy of 88% and a $118 monthly rate, the facility clears that comfortably, but during the lease-up it does not, which is why the working capital is as important as the build-out.
Almost no cost of goods
Revenue Map's presets set COGS at just 3% for self storage, covering lock replacements and a small insurance resale. That produces a gross margin near 97%, the highest of any vertical in the model library. The economics feel misleading until you realize that the capital cost, not the operating cost, is what makes the business hard to start. Once the lease-up is over, almost every dollar of monthly rent above fixed costs and debt service is profit.
