A 50,000 sq ft project typically lands at $3M-$5.5M all-in. Here's the complete breakdown so your pro forma isn't built on guesses.
Development Cost Breakdown
| Category | $/Sq Ft | 50,000 Sq Ft | % of Total |
|---|---|---|---|
| Land acquisition | $8-$20 | $400K-$1M | 15-25% |
| Site work (grading, paving, utilities) | $6-$12 | $300K-$600K | 10-15% |
| Building construction | $25-$50 | $1.25M-$2.5M | 40-50% |
| HVAC (climate-controlled) | $4-$8 | $200K-$400K | 5-10% |
| Security (cameras, gate, access) | $1-$3 | $50K-$150K | 2-4% |
| Soft costs (architect, permits, legal) | $3-$6 | $150K-$300K | 5-8% |
| Office/management area | $1-$2 | $50K-$100K | 1-3% |
| Signage and marketing launch | $0.50-$1 | $25K-$50K | 1-2% |
| Contingency (10%) | $5-$10 | $250K-$500K | 10% |
| Total | $53-$112 | $2.7M-$5.6M | 100% |
Single-Story Drive-Up vs. Multi-Story Climate
| Type | Build Cost/Sq Ft | Revenue/Sq Ft/Yr | Yield on Cost |
|---|---|---|---|
| Single-story drive-up | $45-$65 | $8-$12 | 13-18% |
| Multi-story climate | $70-$110 | $14-$22 | 15-20% |
Multi-story costs more to build but generates higher revenue per square foot. In urban areas where land is expensive, multi-story is often the only viable option — and the yield on cost can actually be higher due to land efficiency.
Land: The Most Variable Cost
Self-storage land requirements by type:
- Single-story drive-up (50K sq ft): 2.5-4 acres needed. Land: $200K-$800K
- Multi-story (50K sq ft): 0.75-1.5 acres. Land: $300K-$1.5M (smaller lot, but higher per-acre cost)
Key land criteria: Visibility from a major road (50,000+ cars/day ideal), easy access (right-in/right-out), zoning already permits storage (rezoning adds 6-18 months and $20K-$100K in costs), and within 3-5 miles of rooftops (residential density drives demand).
Construction Cost Drivers
Steel Prices
Self-storage buildings are mostly steel. Steel prices in 2026 have stabilized at $800-$1,000/ton after the 2022 spike to $1,800+. This represents 25-35% of building cost. Lock in steel pricing early with your builder.
Concrete
Slabs, foundations, and retaining walls. Concrete at $150-$200/cubic yard. A 50,000 sq ft slab: $100K-$175K. Multi-story requires more foundation work: $150K-$300K.
Unit Doors
Roll-up doors are $200-$600 each depending on size. A 400-unit facility needs 400 doors: $80K-$240K. This is a line item many developers underestimate.
Financing
Typical self-storage construction loan:
- Loan-to-cost: 70-80% (you bring 20-30% equity)
- Interest rate: Prime + 1-2% (currently 8-10%)
- Term: 2-3 year construction + 5-7 year permanent (mini-perm)
- Equity required for $4M project: $800K-$1.2M
SBA 504 loans offer better terms (lower down payment, fixed rate for 25 years) but require owner-occupied status and take longer to close.
Timeline: Expect 12-18 Months
- Site selection and due diligence: 2-4 months
- Permitting and design: 3-6 months (varies wildly by jurisdiction)
- Construction: 6-10 months
- Lease-up to stabilization: 12-24 months after opening
- Total from start to stabilized cash flow: 2.5-4 years
