50×100 Metal Building: Commercial Scale, Priced Honestly
A 50×100 is 5,000 square feet — real commercial scale. Warehouse with racking rows, equipment dealership shop, indoor storage business, church multipurpose hall. At this size, steel's per-square-foot advantage over conventional construction is at its widest.
2026 price ranges for a 50×100
| Scope (5,000 sq ft) | Typical 2026 range |
|---|---|
| Steel building kit only (engineered, delivered) | $50,000 – $85,000 |
| Kit + professional erection | $75,000 – $120,000 |
| Turnkey (kit, concrete slab, erection) | $110,000 – $175,000 |
Per-square-foot reality check
Turnkey, a 50×100 typically lands at $22–$35/sq ft in 2026 — compare that with $80–$150+/sq ft for conventional commercial construction. The spread pays for a lot of interior fit-out.
- Fire code: above ~5,000 sq ft (varies by state and occupancy) sprinkler and separation requirements can kick in — check occupancy class early.
- Loading: dock-height doors vs. grade-level changes your slab design, not just your doors.
