Cost to Build Self-Storage: Calculator & ROI Estimator

Estimate your all-in build cost and project a rough investment return — with honest ranges, labeled assumptions, and no fake precision.

1. Your building

Single-story, drive-up units with roll-up doors.

Enter width × length above, or type total square footage directly.

Qualitative only — higher-load sites trend toward the top of the band.

2. Investment assumptions

These are editable assumptions, not ROI's market data. Enter your own market's numbers.

Gross → net rentable after aisles. ~70% is typical; adjust for your layout.

Enter your local market rate — we don't assume one for you.

Stabilized assumption.

Of gross revenue.

Estimated total build cost

Enter your dimensions to see an estimate.

Estimated total range includes the building package, steel erection, and concrete/site work (national averages). Excludes land, permits, utilities, and other soft costs. Your real number is confirmed in a written quote.

Enter rentable efficiency, market rent, and occupancy to project revenue and payback.

Directional only. Simple payback divides the estimated total build cost by projected gross revenue — it excludes land, financing, and operating costs. Not a financial guarantee.

How this estimate works

The tool multiplies your area by our published all-in estimated totals (national averages), read from one shared source so the numbers never drift:

  • Standard drive-up: $23.50–$33.00/sq ft.
  • Climate-controlled: $30–$42/sq ft.
  • Boat & RV: $25.50–$36.00/sq ft.
  • Flex spaces: $36+/sq ft.
  • Conversion / retrofit: $10.50–$16.00+/sq ft.

Still deciding on a footprint? The building sizes guide covers what each one typically yields.

What this includes: building package, steel erection, and concrete/site work. It excludes land, permits, utilities, and other soft costs.

The ROI projection:rentable square feet (after aisles) × your market rent × 12 months × occupancy gives projected gross revenue; the estimated build cost divided by that revenue gives a simple payback range. Every input is yours — we don't inject market rent or occupancy as if they were our data.
