Metal garage kits: price and size guide

In recent years, metal garage kits have become a popular choice for those seeking secure, sturdy, and affordable storage for their vehicles, tools, or equipment. Thanks to their easy installation, durability, and lower cost compared to traditional construction, more and more homeowners are opting for this prefabricated structure. Whether you need a single-car garage, additional storage space, or a larger workspace, garage kits offer flexible options to suit different needs and budgets. In this guide, you'll find all the information you need about pricing, features, and how to choose the best option for your project.

5 Important Factors Before Buying a Garage Kit

When considering a metal garage kit purchase, several crucial factors determine both the initial investment and long-term satisfaction. First, local building codes and permit requirements vary significantly by location, potentially affecting foundation specifications and structural modifications. Second, the gauge of steel used in construction directly impacts durability and price, with 14-gauge steel offering superior strength compared to 20-gauge alternatives. Third, roof style selection between gable, gambrel, or lean-to designs affects both cost and snow load capacity. Fourth, foundation preparation requirements can add substantial expenses, particularly in areas with challenging soil conditions or strict frost line regulations. Finally, assembly complexity varies between manufacturers, with some kits requiring professional installation while others accommodate skilled DIY builders.

Real-Life Use Cases

Metal garage kits serve diverse purposes beyond simple vehicle storage. Rural property owners frequently use larger 30x40 foot structures as equipment storage for tractors, hay, and farming implements. Urban homeowners often choose compact 12x20 foot units for workshop space combined with car protection. Commercial applications include small business storage, automotive repair facilities, and retail equipment housing. Climate considerations play a significant role, with northern regions favoring steeper roof pitches for snow shedding, while coastal areas require enhanced corrosion resistance. Many buyers customize their kits with additional windows, walk-through doors, and insulation packages to create multi-purpose spaces that function as workshops, hobby areas, or small business locations.

Reference Price Range

Metal garage kit pricing varies considerably based on size, gauge, and features. Basic 12x20 foot single-car units typically range from $2,500 to $4,500, while 24x24 foot two-car structures cost between $4,500 and $8,000. Larger 30x40 foot commercial-grade units can range from $8,000 to $15,000 or more. Premium features like insulation, upgraded doors, and enhanced ventilation systems add 20-40% to base prices. Installation costs, when required, typically add $2,000 to $5,000 depending on complexity and regional labor rates.


Size Basic Kit Price Premium Features Installation Estimate
12x20 ft $2,500-$4,500 $3,500-$6,000 $1,500-$3,000
24x24 ft $4,500-$8,000 $6,500-$11,000 $2,000-$4,000
30x40 ft $8,000-$15,000 $12,000-$22,000 $3,000-$6,000

Choose the Garage Kit That Best Suits You

Selecting the optimal metal garage kit requires balancing immediate needs with future expansion possibilities. Consider your primary use case: simple vehicle protection requires basic features, while workshop functionality demands enhanced lighting, electrical provisions, and insulation. Size calculations should account for vehicle dimensions plus adequate maneuvering space, typically adding 4-6 feet to vehicle length and width measurements. Climate factors influence material selection, with galvanized steel offering superior corrosion resistance in humid environments. Budget considerations extend beyond initial purchase price to include foundation preparation, electrical installation, and ongoing maintenance costs. Warranty coverage varies significantly between manufacturers, with reputable companies offering 10-20 year structural warranties and shorter coverage for paint and finish components.

Researching local dealers and comparing installation services ensures proper assembly and compliance with building codes. Many manufacturers provide detailed assembly instructions and customer support, making DIY installation feasible for mechanically inclined buyers. Professional installation guarantees proper foundation attachment and structural integrity but increases total project cost. Consider seasonal timing for installation, as spring and fall typically offer optimal weather conditions and contractor availability. Finally, evaluate expansion possibilities, as adding lean-to sections or modifying existing structures often proves more cost-effective than complete replacement.
