How Much Does a Metal Garage Cost?

The cost of a metal garage depends on its size, steel gauge, roof style, local building code requirements, and optional upgrades. In 2026, most homeowners can expect the following price ranges for the steel structure with delivery and installation:

Garage Size                                  Typical Installed Cost

12×20 (Single Car)                        $6,999–$9,000

20×20                                                $6,500–$14,000

24×24 (Two Car)                            $9,700–$16,000

24×30                                                $9,700–$18,900

30×40 (Workshop)                         $15,400–$28,200

40×60                                                $25,000–$52,000+

Average Cost Per Square Foot

Most metal garages cost approximately:

• $11–$20 per square foot for the steel building, delivered and installed.
• Larger garages generally cost less per square foot because fixed material and labor costs are spread over a larger footprint.

What Is Included?
A standard quote typically includes:

• Steel frame and panels
• Roof system
• Delivery
• Professional installation
• Standard anchors

​Most quotes do not include:

• Concrete slab
• Site preparation
• Permits
• Electrical or plumbing
• Insulation
• Interior finishing

Additional Costs to Budget For
Beyond the garage itself, consider these common expenses:
Item
Typical Cost
Concrete slab 
     $12–$15 per sq. ft.

Permit fees
     $100–$600

Roll-up garage door
     $850–$3,450

Walk-in door
     $350–$750

Windows
     $350–$600 each

Insulation
     $0.50–$2.20 per sq. ft.

Engineering certification
$400–$900

Factors That Affect Price
Several variables influence the final cost:

• Garage size: Larger buildings have a lower cost per square foot.
• Steel gauge: Heavier 12-gauge framing costs more than 14-gauge but offers greater strength.
• Roof style: Vertical roofs are more expensive than regular or A-frame roofs but provide better drainage and snow shedding.
• Wind and snow load certification: Areas with stricter building codes require additional engineering.
• Customization: Doors, windows, lean-tos, insulation, and extra height all increase the total price.

Sample Project Budgets

• Basic 20×20 garage: $6,500–$10,000
• 24×30 two-car garage: $10,000–$18,000
• 30×40 workshop: $15,000–$28,000
• 40×60 commercial garage: $25,000–$52,000+ (building only)

Total Turnkey Cost
Once you include the foundation, permits, utilities, and optional upgrades, the total project budget is often 30–70% higher than the advertised building price. For example, a 30×40 metal garage with a concrete slab, insulation, roll-up doors, and permits can realistically cost $28,000–$40,000+ depending on location and specifications.
