How Much Does It Cost to Start a Self Storage Facility?
A self storage facility typically costs $700,000 to $1,750,000 for the build-out depending on format, plus $500,000 in working capital to survive the lease-up. Revenue Map's default preset models a 300-unit facility at $1,400,000, financed with a $1,050,000 loan at 7.5% over twenty years, with 97% gross margin and an eighteen-month ramp from 25% to stabilized occupancy.
The total investment for a self storage facility runs from roughly $1,200,000 for a portable containers operation to over $2,200,000 for a new climate-controlled build, once working capital is included. Unlike most businesses, the operating cost is tiny: COGS sits at just 3%, producing the highest gross margin in Revenue Map's model library at roughly 97%. The expense is almost entirely capital: buying or building the facility, equipping it with doors, gates and cameras, and then financing twelve to eighteen months of operating losses while occupancy ramps.
Revenue Map's default preset models a 300-unit facility at $1,400,000 capex with a $1,050,000 loan. The industry presets cover five additional formats from portable containers at $700,000 to climate-controlled units at $1,750,000. The cost table below breaks out each line so you can match the investment to the format and the market size.
Cost Breakdown

What Moves the Number
Capital cost, not operating cost, defines the business
Revenue Map's presets set COGS at 3%, producing a 97% gross margin. Monthly operating costs at launch total roughly $8,900, modest for a business that can eventually generate over $30,000 per month at stabilized occupancy. The challenge is the $1,400,000 build-out and the $500,000 of working capital needed before that stabilized revenue arrives. Almost all of the financial risk is front-loaded.
Format determines the investment range
A portable containers operation presets at $700,000 with 220 units at $135 to $150 per month and a $500,000 loan. A conversion facility, repurposing an existing building, comes in at $1,100,000 for 400 units at $98 to $110 per month. Climate-controlled storage runs $1,750,000 for 260 units at $145 to $160 per month with a $1,310,000 loan. The per-unit revenue and occupancy speed vary as much as the upfront cost.
The lease-up period drives working capital needs
Revenue Map's presets model an 18-month ramp starting at 25% of phase-one demand, with phase-one occupancy at 45%. At launch, a small fraction of 300 units are occupied, producing far less revenue than the combined debt service and operating costs. The $500,000 phase-one investment covers this deficit. A facility in a market with slower absorption could need more.
Debt service is the largest fixed cost
The default $1,050,000 loan at 7.5% over twenty years produces a monthly payment of roughly $8,500, nearly matching the entire monthly operating cost. By phase three, at 88% occupancy and a $118 monthly rate, the facility generates enough to cover both comfortably. But during the lease-up, debt service is the bill that cannot be deferred.
