STEP 3
Get Your Building Permit and Prepare the Site for Your Prefab Metal Building
In most US states, installing a metal building requires a permit. You’ll need to get your permit and prepare the site before we can schedule installation. We’ll provide basic engineered plans for permitting once you make your purchase.
Most metal buildings require a concrete slab foundation, while smaller ones can do with a simple level gravel pad.
Slab Sizing and Ledges
Typically, your slab should be slightly larger than the metal building.
For gravel pad
We recommend your gravel pad to be 2 feet longer and 2 feet wider than your metal building size.
For concrete pad
Typically, we recommend your concrete pad to be at least 1 foot longer and 1 foot wider than your metal building size. Use our concrete pad calculator to confirm your pad size.
If local regulations require an additional ledge, it can be sloped or lowered to prevent water from pooling next to your building’s base rail.
Foundation Installation:
Most metal buildings require a concrete slab foundation. Unfortunately, we are not able to install the foundation. You’ll need to prepare this before your building can be scheduled for installation. Your local planning or building department can provide specific foundation requirements for metal buildings in your area.
Slab Sizing:
Typically, your slab should be slightly larger than the metal building. Use our online concrete pad size calculator to determine the correct slab size for your location. If local regulations require an additional ledge, it can be sloped or lowered to prevent water from pooling next to your building’s base rail.
Customization Options for Your Metal Building Explained
Sturdy Steel Framing
Your metal building will be constructed with premium steel studs. Choose between 14-gauge framing for general-purpose buildings or 12-gauge framing for additional strength and durability.
The 12-gauge steel framing has a 20-year rust-through warranty and is a good choice for long-term use. Our extra-wide buildings use sturdy steel trusses to span wide areas safely without columns.
Durable Roofing Options
For roofing, you can choose between 29-gauge steel panels or thicker, commercial-grade 26-gauge panels. The 29-gauge panels are ideal for mild climates. The 26-gauge panels are perfect for areas that regularly get snow or harsh weather, or those who want to maximize their building’s longevity.
Large building always come with a premium vertical roof. Smaller buildings and budget is a concern, we offer two additional, less expensive roof styles that require more maintenance to keep clean.
Classy Siding Options
The siding of your building will be crafted from steel panels with the same gauge as the roofing, ensuring consistent quality and durability. Choose between horizontal or vertical siding based on which style you prefer, seen below.
Color Options
Choose between a wide selection of colors for your roof, trim, and siding. For a more classy look, consider our two-tone (wainscot) option, which features a different color on the lower portion of your building.
Frame Outs and Lean-Tos
If you want to install your own garage doors, walk-in doors, or windows, we can do custom frame-outs for a small fee.
We are also able to add custom lean-tos on either side of your main structure.
For any customizations that aren’t available in our 3D builder, just call or email our friendly building specialists to discuss options and pricing.
Insulation
When customizing your building, choose from three insulation options:
- Woven R17 insulation: Effectively reduces condensation buildup. This insulation controls hot and cold temperature with an R-value of 17, suitable for more demanding temperature environments.
- No insulation: Choose this if you aren’t concerned about condensation buildup or temperature control.
- Double Bubble insulation: Helps reduce condensation buildup. This insulation only has an R-value of 1, which is ideal for minimal insulation needs.
Optional Add-on Features
We have a variety of roll-up garage doors available from 6’x6′ up to 16’x16′ in size. Chain hoists are also available for purchase.
For easy entry for people, we offer two styles of walk-in doors: one with a window, and one without. We also have two different styles of windows available.
Sturdy Steel Framing
Your metal building will be constructed with premium steel studs. Choose between 14-gauge framing for general-purpose buildings or 12-gauge framing for additional strength and durability.
The 12-gauge steel framing has a 20-year rust-through warranty and is a good choice for long-term use. Our extra-wide buildings use sturdy steel trusses to span wide areas safely without columns.
How Tall Should Your Metal Garage Be?
Different metal buildings will have different heights depending on their use. For example, an RV garage will need to be taller than a tool shed.
Use our roof brace clearance and peak height calculator to choose the right leg height for your metal building.
Roof Center Brace Clearance & Peak Height
Select your carport or garage preferences to see the center clearance and peak height.
Learn more about height clearance and building heights on our Height Clearance Calculator page.

Our metal buildings are engineered for durability and designed to meet or exceed standard requirements. For areas with harsh weather, we offer upgrades like thicker 12-gauge steel framing and building certifications for specific wind speed ratings (e.g., up to 140 mph or more) and heavy snow loads (measured in pounds per square foot).
Opting for features like a vertical roof style also enhances performance in heavy snow regions. Discussing your local conditions with our building specialists will help ensure your structure is properly configured.
Beyond the foundation itself, the most crucial preparation step is ensuring your site is level (or within a few inches of level) before the installation crew arrives. For a seamless installation experience, you must also provide clear, unobstructed access to the building site for our delivery truck and crew.
Yes. You usually need a building permit to install a metal building on your property. However, requirements for metal buildings vary greatly depending on your specific location (state, county, city) and the size or intended use of the structure. For example, in some jurisdictions, you can install a carport without a permit since it’s not considered a permanent structure.
You must check with your local building department to determine if you need a permit, and you have to get it before we schedule your metal building’s installation. We can provide standard engineered drawings upon request to assist with your permit application process if needed.
The price of metal buildings depends on factors like size, style (roof type, etc.), the materials you choose (steel gauge, siding options), and any added features like doors, windows, or insulation.
You can check prices quickly by using our custom carport pricing tool or garage design builder—just pick the structure you need, customize it, and get real-time pricing!
All of our metal buildings come with a 1-year workmanship warranty from the installation date. Additionally, if you upgrade to the optional 12-gauge steel framing, you receive a 20-year rust-through warranty on the framing and most roof panels.
