A 30x30 metal building is a size that’s perfect for storage, but with 900 square feet, it gives you room to do more.

In 2026, a 30x30 metal building will typically cost somewhere between $15,000 and $45,000+ for the building itself. Once you add the other parts of the project, like concrete, preparation, permits, and upgrades, a realistic budget is often closer to $22,000 to $60,000+.
