The 24×30: A Two-Car Steel Garage Done Right
At 720 square feet, the 24×30 is the steel answer to the two-car garage — two full bays plus a workbench, or one bay and a genuine workshop. It's also the size where steel starts beating stick-built on price in most markets.
2026 price ranges for a 24×30
| Scope (720 sq ft) | Typical 2026 range |
|---|---|
| Steel building kit only (engineered, delivered) | $9,000 – $16,000 |
| Kit + professional erection | $14,000 – $24,000 |
| Turnkey (kit, concrete slab, erection) | $22,000 – $38,000 |
Layout notes
- Two 9×8 roll-ups on the 24-ft gable end is the standard two-car setup.
- One 10×10 door on the 30-ft side wall leaves the gable free for a future lean-to.
- 10-ft eave instead of 9-ft is cheap insurance if you ever want a lift.

Can I put a 24x30 metal building on an existing slab?
Often yes, if the slab is 4 inches or thicker, level, and large enough for the anchor-bolt pattern — but the frame must be engineered to match the existing footprint, and your inspector may require footing verification.
