Frequently asked questions

Will I need a permit for my 40×40 metal building?
It depends on your land, building size, and how you plan to use it. Check with your local building office before ordering. We provide stamped engineering plans for the agreed design. Your local office decides which permits and site plans you need.
What can I customize on a 40×40 metal building?
Choose the width, length, wall height, roof style, colors, and door and window openings. You can add lean-tos, interior walls, insulation, and door packages. Your quote lists each item. A framed opening does not include the door or window unless listed.

What can I do with a 40×40 metal building besides storing vehicles?
Use it as a workshop, equipment shed, hobby room, or home gym. You can also split the space between work and storage. Tell us about any living or business use so we can plan the building for it.
What kind of foundation will I need?
Your foundation must suit the building, soil, and local rules. Get approved plans before pouring concrete. Tell your foundation designer about vehicle lifts or heavy equipment. Site work, foundation design, and concrete are priced separately from the steel kit.
How long does delivery take, and is it included?
Most kits arrive 2–6 weeks after your order and plans are approved. Standard delivery is included for eligible locations. We confirm the schedule and truck access before shipping. You will need a crew and equipment to unload the truck.

Can I build it myself, or can you help me find an installer?
You can use your own qualified crew with the tools and equipment needed to follow the plans. We can also help you find an independent installer where available. Installation, concrete, and other site work are quoted separately.
How will I know what is happening with my project?
Your online project tracker shows updates on plans, permits, production, and delivery. You can see which steps are done and what comes next. Call our team if you have a question or need to change something.
