Detached Metal Garages

You’ve done this before. You call three companies about detached metal garages and get three wildly different answers. One says $8,000. Another says $14,000. The third won’t talk numbers until you sit through an on-site sales pitch.

That confusion is by design. Dealers bury pricing behind phone trees and pressure tactics, and buyers end up overpaying by 20–30% because they never saw honest numbers. Then the surprises hit at signing — delivery fees, separate installation costs, upgrades that were supposedly standard.

We started Bargain Metal Buildings because we were tired of watching that happen. You get honest, itemized pricing, and you’ll know what’s included in your installed price before you ever pick up the phone. Call us at (866) 941-4072 or schedule a free consultation.

Detached metal garage prices range from roughly $4,200 for an 18×20 structure to $27,000+ for a 45×60 building, with most customers landing between $8,000 and $16,000 for a fully installed garage. Size is the single biggest factor in your total cost. And because we buy direct from the manufacturer, you skip the dealer markups that inflate prices by 25-40%.

18×20 Metal Garage (360 sq ft) – Starting at $4,200 installed Great for single-car storage or a compact workshop. Base price covers 14-gauge steel framing, a vertical roof for proper drainage, one 9×8 garage door, one walk-in door, and your pick of 16 colors.

20×20 Metal Garage (400 sq ft) – Starting at $5,100 installed That extra width gives you real clearance around your vehicle, plus room for shelving or storage cabinets along the walls. Makes a noticeable difference.

24×25 Metal Garage (600 sq ft) – Starting at $7,800 installed Fits one vehicle with generous workshop space, or two compact cars parked tight. The extra square footage works out to about $13 per square foot installed.

24×40 Metal Garage (960 sq ft) – Starting at $11,500 installed This is one of our best sellers — and for good reason. The 24×40 gives you comfortable two-car storage with room left over for workbenches, tools, and equipment. Standard configuration includes two 9×8 garage doors up front and one walk-in door.

30×35 Metal Garage (1,050 sq ft) – Starting at $13,200 installed If you’re parking trucks or SUVs, the 30-foot width makes life significantly easier. Extra clearance on both sides means no more holding your breath while opening doors.

30×40 Metal Garage (1,200 sq ft) – Starting at $14,900 installed Versatile is an understatement. Two-car storage with a dedicated workshop area, or vehicles plus recreational equipment — this size handles it all. Your cost per square foot drops to about $12.40 here.

35×40 Metal Garage (1,400 sq ft) – Starting at $17,600 installed Three vehicles side-by-side, or two vehicles with serious workshop space. We see a lot of small business owners and dedicated hobbyists go with this configuration.

40×50 Metal Garage (2,000 sq ft) – Starting at $23,400 installed Commercial-grade territory. Room for four vehicles, or a mix of vehicle storage and substantial workspace. We can set up multiple garage doors on different walls so traffic flows the way you need it to.

45×60 Metal Garage (2,700 sq ft) – Starting at $27,800 installed Our largest standard residential size — nearly 3,000 square feet of protected space. Perfect for RV storage, vehicle collections, or combining storage with a full-blown workshop.

Cost per square foot covers just the base material — steel, framing, and basic structure without delivery or installation. Total installed price? That’s everything: materials, delivery to your door, professional installation, anchoring, and cleanup. Turnkey.

And this is where a lot of competitors get sneaky. They’ll advertise ‘$8 per square foot’ for a 30×40 garage, which sounds like $9,600. Reasonable, right? Then comes $1,800 for delivery. Another $2,400 for installation. $600 for anchoring. $400 for the vertical roof. Suddenly you’re at $15,200. We quote total installed pricing from day one — because that’s the number that actually matters.

Every quote we give covers everything you need for a complete, ready-to-use garage:

Materials and Manufacturing: Premium 14-gauge steel framing, vertical roof panels for superior water drainage, certified wind and snow load engineering, 16 color options, rust-resistant galvanized steel, all trim and flashing, and a 20-year rust-through warranty.

Delivery: Free transportation anywhere in the United States, scheduled with advance notice, coordinated around your availability.

Professional Installation: An experienced crew handles complete assembly, anchoring to concrete or ground anchors (provided), leveling and alignment, door and trim installation, and cleanup of all packaging materials.

The only things not included are site preparation (you’ll need a level surface), local permits if your municipality requires them, and optional add-ons like extra doors, windows, or insulation beyond the base setup.

Thicker steel — meaning lower gauge numbers — costs 15-20% more than thinner options, but delivers dramatically better durability, wind resistance, and lifespan. Worth the investment.

14-Gauge Steel (Standard): Our standard framing measures about 0.0747 inches thick. It handles wind speeds up to 140 mph and snow loads up to 35 pounds per square foot — solid performance for residential garages in most climates. 14-gauge structures maintain their structural integrity for 30+ years with minimal maintenance.

12-Gauge Steel (Heavy-Duty Upgrade): At roughly 0.1046 inches thick, 12-gauge is about 40% thicker than 14-gauge. Expect a 15-20% bump in base price, but you get certified performance in winds up to 170 mph and snow loads over 40 pounds per square foot.

We push 12-gauge for commercial use, severe weather regions, and anyone storing high-value equipment. And a word of caution — plenty of budget dealers use 16-gauge or 18-gauge steel to hit bargain-basement prices. Those thinner materials develop maintenance issues 50-70% more often than 14-gauge. You save money upfront, then pay for it later.

We offer three roof styles — regular horizontal, boxed eave, and vertical — with vertical roofs running 10-15% more than regular roofs but providing far better water drainage and snow shedding.

Regular Horizontal Roof: Most affordable option. Panels run horizontally from side to side. Fine for mild climates where heavy snow and rain aren’t regular concerns.

Boxed Eave Roof: A-frame design with horizontal panels. Better aesthetics, improved water runoff versus regular roofs. Mid-range pricing.

Vertical Roof: Our go-to recommendation. Panels run from peak to eave, so water and snow slide right off. Prevents debris buildup and extends roof life considerably. Most building codes in snow-prone areas actually require vertical roofs for structures above certain sizes.

How long does delivery and installation take? Most metal garages are delivered and installed within 2-4 weeks of order confirmation, depending on your location and our production schedule.

Do you require a deposit? Yes — we collect a deposit to start manufacturing your custom garage. The remaining balance is due when installation wraps up.

Can I install the garage myself to save money? We include professional installation in every quote because proper assembly is essential for structural integrity and warranty coverage. DIY installation voids the warranty.

What foundation do I need? A level surface — concrete slab, gravel pad, or compacted earth. We provide ground anchors for non-concrete installations.

Are permits required? That depends on your municipality. We supply engineered drawings that meet most building codes, but pulling local permits is on you.
