Customize & Build Your 30×30 Metal Building Online
Every option below is selectable in our free 3D builder or your custom quote. The 30′ x 30′ footprint stays the same. Roof style, leg height, gauge, doors, windows, color, insulation, and certification are all yours to choose.
Leg Height (9′ to 20′)
The 30×30 footprint stays fixed while leg height is yours to choose. Garages commonly use 10′ to 12′. RV, equipment, and farm buildings often use 12′ to 16′. Commercial and lift-ready workshops can go up to 20′ for overhead clearance.
3 Roof Styles
Regular Roof is the most affordable. A-Frame Horizontal / Boxed Eave gives a traditional peaked roofline. Vertical Roof is recommended for snow, rain, and long-term water management, especially for enclosed 30×30 garages and workshops.
Roof Pitch & Slope
Standard 3:12 roof pitch on most 30×30 buildings. Upgrade to 4:12 or 5:12 pitch for heavy snow regions, a steeper look, or to better match nearby residential and farm structures.
Frame Gauge (14 or 12)
14-gauge galvanized steel tubing comes standard and works well for most residential 30×30 garages, carports, and storage buildings. Upgrade to 12-gauge for commercial use, heavy tools, machinery, or harsher climates.
Sheet Metal Gauge (29 or 26)
29-gauge sheet metal panels are standard for roof and walls. Upgrade to 26-gauge in hail-prone areas, coastal regions, high-use commercial sites, or when you want a heavier exterior panel.
Certification & Engineering
Certified 30×30 buildings include stamped engineered drawings, foundation details, and wind / snow load calculations matched to your local code. Recommended for permitted garages, commercial buildings, and high-wind or snow regions.
Roll-Up Garage Doors
Roll-up garage doors from 6’x6′ up to 14’x14′ are available. A common 30×30 garage uses two 10’x8′ or 10’x10′ doors, while equipment storage and RV layouts may use 12′ or 14′ wide doors.
Walk-In Doors
36″ personnel doors with full frames, weatherstripping, and locksets. Place walk-in doors on the front, side, or rear walls to match your traffic flow, storage layout, or workshop access plan.
Hydraulic & Rapid Doors
For commercial or frequent-use applications, choose hydraulic one-piece doors or high-speed rapid-roll doors. These are useful for service bays, fleet access, and light industrial workspaces.
Windows & Skylights
30″x30″ insulated glazing standard, with 36″x36″ and custom sizes available. Add windows for natural light in workshops, offices, gyms, hobby rooms, and enclosed garages.
Framed Openings
Order framed openings now for future doors, windows, HVAC units, exhaust fans, or wall penetrations. This saves cutting later and keeps your 30×30 structure cleaner and easier to finish.
Garage Door Openers & Windows
Chain-drive, belt-drive, and smart Wi-Fi-enabled openers are available. Window kits for roll-up doors add daylight while keeping vehicles, tools, and equipment protected.
17 Standard Color Options
Choose from Barn Red, Beige, Black, Brown, Burgundy, Burnished Slate, Clay, Galvalume, Green, Patriot Red, Pewter Gray, Quaker Gray, Rawhide Tan, Royal Blue, Sandstone, Slate Blue, and White.
Mix-and-Match Roof, Walls, Trim
Pick different colors for your roof, wall panels, and trim. Popular 30×30 combinations include Pewter Gray with Black trim, White with Barn Red roof, or Galvalume roof with darker wall panels.
Wainscoting (Two-Tone Walls)
Add wainscoting for a premium two-tone look. Lower 3′ to 4′ wall panels in a contrasting color help the building match homes, barns, shops, or commercial storefronts.
Galvalume (Bare Metal Finish)
Galvalume is a hot-dipped aluminum-zinc coating with no paint. It is cost-effective, corrosion-resistant, and common for agricultural, utility, and industrial-style 30×30 buildings.
Painted Trim & Flashings
Color-matched ridge caps, eave trim, corner trim, gable trim, and rake trim. Hardware can include color-coded screws to match your panel choice for a clean finish.
Custom Color Match
Need to match an existing shop, barn, home, HOA requirement, or brand color? Custom paint matching is available for an upcharge. Ask your building advisor for samples and approval documentation.
Insulation Options
Choose single-bubble, double-bubble, fiberglass batt, spray foam, or insulated metal panels. Insulation is recommended for 30×30 workshops, gyms, offices, and year-round garage use.
Lean-To Additions
Add a lean-to on one or more sides of your 30×30 building for extra covered storage, feed protection, firewood, trailers, outdoor work zones, or equipment overhangs.
Mezzanines & Lofts
A 30×30 can support partial loft storage when engineered correctly. This is useful for boxes, seasonal tools, office storage, or workshop supplies while keeping the main floor open.
Interior Partitions
Divide the 900 sq ft into work zones, storage rooms, offices, mechanical rooms, or tool cages. Steel stud partitions or insulated interior metal panels are available for mixed-use layouts.
Trim, Anchors, Gables
Decorative trim around doors, rooflines, and corners creates a finished look. Gables and trim color contrast can help your 30×30 match nearby homes, shops, or barns.
Flooring Prep
We do not pour foundations, but we guide you on slab specs. A 30×30 commonly uses concrete for enclosed garages and shops, while gravel or compacted dirt can work for open storage or agricultural use.
Wind & Snow Certification
Standard 115 MPH wind and 35 PSF snow load. Certified upgrades are available up to 170+ MPH wind for hurricane and coastal zones, and 65+ PSF snow load for heavy snow regions.
Permit-Ready Drawings
Stamped engineered drawings, foundation plans, and code calculations. Meets IBC, IRC, NEC, IFGC, IECC, and IMC requirements when certification is added.
Door Locks & Access Control
Slide bolts, deadbolts, keypad entry, smart locks, and Wi-Fi connected garage door openers are available. Commercial users can add auto-lock and controlled access systems.
Fire Safety & Alarms
Smoke and heat detectors, extinguishers, emergency exit signage, and sprinkler-ready configurations are available for commercial 30×30 builds based on local requirements.
Anchoring System
Concrete wedge anchors for slab installs, asphalt anchors for paved lots, mobile-home anchors for existing pads, or auger ground anchors for dirt and gravel. Anchors are matched to your surface.
Solar & Roof-Top Loads
Engineered framing can support solar panels, satellite dishes, HVAC condensers, and rooftop equipment when specified during design. Reinforced roof options are available.
30×30 Metal Building Codes, Permits & Engineering
Every 30×30 prefab steel building can be engineered, stamped, and certified to meet your local building codes. Certification is recommended for permitted garages, commercial builds, high-wind regions, and heavy-snow areas.
We also follow plumbing codes, energy conservation standards, and any state or local requirements. Our team helps align your 30×30 building with the code requirements for your intended use.
How to Maintain a 30×30 Metal Building

How Much Does a 30×30 Metal Building Cost?
No hidden fees on any 30×30 prefab steel building. A 30×30 metal carport starts around $7,995, an enclosed garage or workshop from $10,995, a metal barn from $9,995, and a commercial certified build from $13,995. Final price depends on roof style, enclosure, gauge, doors, height, certification, location, and upgrades.
Building Configuration
A 30×30 carport is the lowest-cost entry point. Enclosing it as a garage or shop adds wall panels, doors, trim, and labor. Commercial certification and heavier framing increase the final price.
Your Location
Delivery distance, regional labor rates, state requirements, wind exposure, snow load, and local permit rules affect your final 30×30 building price.
Steel Gauge
14-gauge galvanized tubing comes standard. Upgrade to 12-gauge for heavier use, stronger framing, longer warranty options, and commercial or equipment-heavy 30×30 buildings.
Roof Style & Pitch
Regular Roof is most affordable. A-Frame Horizontal adds curb appeal. Vertical Roof costs more but is recommended for long-term durability, snow regions, and enclosed 30×30 buildings.
Certification
Certified buildings cost more but include stamped engineering and site-specific load calculations. Certification is recommended for permits, commercial use, coastal zones, and snow regions.
Doors, Windows, Insulation
Roll-up doors, walk-in doors, windows, framed openings, insulation, and wainscoting all affect the final 30×30 price. Larger doors and insulation packages are the most common upgrades.
30×30 Metal Building Complete Price Range
Range covers an open 30×30 carport at the low end through a fully enclosed certified building with 12-gauge upgrade, vertical roof, insulation, multiple doors, windows, and engineered drawings at the high end. Your building advisor confirms exact pricing with your custom quote.

“We needed a 30×30 shop for equipment storage and weekend welding projects. The 12-gauge upgrade feels solid, and the extra height gives us room for shelving and a lift later.”
