Short answers to the questions readers send Diamond Steel Buildings most often, plus where to write if yours is not covered here.
Most basic prefab steel buildings run somewhere between 15 and 25 dollars a square foot for the shell alone, though snow load, wind zone, insulation, and site prep can push a finished project well past that.

Almost always, once the building passes a certain square footage or gets placed on a permanent foundation, though the exact threshold varies by county. Calling the local building department before ordering costs nothing, and a stop work order after delivery costs plenty.
Smaller kits under about 900 square feet are workable for an experienced DIYer with a few extra hands and the right tools, but anything larger or set on a permanent foundation usually needs a crew that has erected steel before. Manufacturer instructions rarely account for uneven ground.
26 gauge is standard for most residential and light commercial buildings, while 29 gauge is thinner and mainly shows up in budget kits that trade some dent resistance for a lower price. For anything in a hail prone region, the heavier gauge usually pays for itself.
A well coated steel building with proper drainage and periodic touch up painting can run 40 years or more, though the finish and fasteners fail well before the panels do if maintenance gets skipped. Rust almost always starts at a scratched edge or a loose fastener, not the flat panel itself.
Steel usually costs more upfront per square foot than a comparable wood pole barn, but it needs less ongoing maintenance and holds insurance value better in areas with termite or rot risk. Which one wins depends more on your local labor costs than the material price alone.
