How Much Is a Metal Carport Cost? Full 2026 Price Breakdown
Ask ten homeowners how much is a metal carport cost and you will get ten different answers, because the price hinges on size, steel gauge, roof style, and whether the manufacturer installs it or you do. As a rough rule of thumb, a basic single-car metal carport kit runs $1,200 to $3,500, while a fully installed double-car unit with a vertical roof and extra height lands between $4,000 and $8,000. Custom builds with enclosed sides, insulation, or a workshop footprint can push past $15,000.
The good news is that a metal carport is almost always cheaper than a wood-framed or brick garage, and it goes up in a day instead of weeks. The trade-offs come down to durability and the fine print. In this guide we break down real per-square-foot figures, kit versus custom pricing, and the installation and site-prep costs most quotes leave out, so you can compare bids without getting burned.
Average Metal Carport Cost by Size
Most manufacturers price metal carports by width, length, and height, which makes size the single biggest driver of the final bill. The figures below come from current builder pricing and are meant for budgeting, not as firm quotes.
| Carport Size | Typical Use | Kit Price Range | Installed Price Range |
|---|---|---|---|
| 12 ft x 20 ft | One car | $1,200 – $2,800 | $2,000 – $4,000 |
| 18 ft x 20 ft | One car + storage | $1,800 – $3,800 | $2,800 – $5,500 |
| 20 ft x 20 ft | Two cars (tight) | $2,200 – $4,500 | $3,200 – $6,500 |
| 24 ft x 26 ft | Two cars + workspace | $3,200 – $6,500 | $4,500 – $9,000 |
| 30 ft x 40 ft | RV or boat storage | $5,500 – $11,000 | $7,500 – $15,000 |
On a per-square-foot basis, metal carports land between $6 and $14 per square foot installed, with the low end covering a simple horizontal-roof kit and the high end covering a taller, certified vertical-roof structure. Smaller units always cost more per square foot because site prep, delivery, and labor are fixed costs that spread thin over a small footprint.
Height Changes the Math
Standard carport legs run 7 to 8 feet tall, which clears a normal sedan or SUV but not much else. Raising the legs to 9 feet adds roughly 10 to 15 percent to the price, and going to 12 feet or higher for an RV or lifted truck adds 20 to 30 percent. If you think you might ever store a boat, trailer, or camper, paying for extra height now is far cheaper than replacing the structure later.
Kit vs. Custom vs. Fully Installed: How Much Is a Metal Carport Cost?
The way you buy makes as much difference as what you buy. There are three basic routes, each with a different total.
- DIY kit (no labor). You buy a bolt-together steel kit and assemble it with friends or family. Kits start around $1,200 for a small single unit. You save $800 to $2,500 in labor but need a level site, concrete anchors, and a full weekend of patient assembly work.
- **Manufacturer-installed. ** Most large carport builders (Carport Central, Alan’s Factory Outlet, and regional dealers) include installation in the quote. This typically adds $700 to $2,000, but you get a crew that erects the frame in a few hours and is responsible for straight, square assembly.
- Custom build. If you want enclosed walls, a lean-to, insulation, roll-up doors, or a specific color to match the house, expect a custom quote. These run $8,000 to $20,000 or more depending on how garage-like the finished product becomes.
For most people, the manufacturer-installed route is the sweet spot. It costs more than a kit but removes the two most common DIY disasters: anchors set in the wrong place and a roof that was never squared off before tightening.
Steel Gauge, Roof Style, and Finish
Two carports with identical dimensions can differ in price by a third, purely from the materials.
Steel gauge. Lower gauge numbers mean thicker steel. A 12-gauge frame costs 20 to 30 percent more than a thinner 14-gauge frame but resists dents, sag, and wind damage far better. For any structure over 20 feet wide or in a windy region, 12-gauge is worth the premium.
Roof style. An A-frame horizontal roof is the cheapest and works fine where snow is light. A vertical roof, where panels run the ridge-to-eave direction over purlins, sheds snow and water fast and holds up in northern climates, but adds $500 to $1,500 to the price. A boxed-eave roof splits the difference.
Galvanization and paint. A standard galvanized finish resists rust for years. A baked-on color coat or a two-tone roof adds $200 to $600 and looks substantially better from the curb. If you live near salt air, pay for the heavier galvanizing.
Site Prep, Foundation, and Permits
The quoted price of a carport is rarely the price you actually pay, because it usually excludes the ground it stands on.
- Site leveling. Builders assume a mostly level site. If the install crew has to level grading or remove a slope, expect $300 to $1,000 on top.
- Foundation. A dirt or gravel pad is cheap, but a concrete slab runs $4 to $8 per square foot, adding $1,800 to $5,200 for a typical two-car footprint. The slab is strongly recommended in wet climates.
- Anchors. Mobile-home style auger anchors cost a few hundred dollars; concrete anchors for a slab are usually included with the slab work.
- Permits. Many municipalities require a permit for any carport over a certain size or any structure tied to the ground. Fees run $50 to $400, and skipping one can bite you when you sell the house.
Regional and Seasonal Price Swings
Where you live changes the sticker price. Builders in Texas and the Southeast (where steel suppliers are dense and demand is constant) quote some of the lowest national prices. Coastal areas, the Northeast, and anywhere with strict wind or snow load codes pay 10 to 25 percent more, both for heavier-gauge steel and higher labor.
Timing matters too. Demand peaks in spring and early summer, so the same carport can cost 5 to 10 percent more in May than it does in December. If you want the best deal, request quotes in the fall or winter, when builders are hungrier and lead times are shorter.
What Most Quotes Leave Out
Read every quote line by line, because these fees are the ones that turn a $3,500 carport into a $5,000 bill.
- Delivery beyond the included radius. Many builders include 30 to 50 miles, then charge per mile beyond it.
- Trim and closure strips. Some budget companies price bare panels and charge separately for gable trim and closure strips that seal out rain.
- Gutters and downspouts. Rarely included, and worth adding if the carport sits beside the house.
- Removal of an old structure. If you are replacing an aging carport, haul-away runs $300 to $800.
Metal Carport vs. Garage: Is the Upgrade Worth It?
A metal carport keeps sun, hail, and light snow off your car for a fraction of a garage. An attached one-car garage runs $10,000 to $25,000, and a detached two-car garage with a slab can pass $30,000. A carport doing the same basic job of shelter costs $2,000 to $9,000 installed.
The catch is security. A carport is open, so it deters weather, not thieves, and it does not protect the vehicle’s interior from blowing rain or extreme cold like a closed space does. If your only concern is protecting the paint and glass from sun and hail, a carport wins on pure value. If you need lockable storage and workspace, start thinking garage or an enclosed carport.

Frequently Asked Questions
How much is a metal carport cost for a basic single car?
A basic 12×20-foot single-car metal carport with a horizontal roof runs roughly $2,000 to $4,000 installed, and a DIY kit for the same footprint starts around $1,200 to $1,800 before site work.
Is it cheaper to build your own metal carport?
Yes, typically $800 to $2,500 cheaper in labor, but only if you already have a level site, the right anchors and tools, and a couple of helpers. Errors in squaring or anchoring are costly to correct, so DIY mainly pays off for small, simple kits.
Do I need a permit for a metal carport?
Often. Rules vary by city and county, but many areas require a permit for any structure over 120 square feet or any carport anchored to a foundation. Check with your local building department before ordering, since fines and forced teardowns are more expensive than a $50 fee.
How long does a metal carport last?
A well-built 12-gauge steel carport with a vertical roof and proper anchoring typically lasts 20 to 30 years with little maintenance. Thinner 14-gauge units in harsh weather may need attention sooner. You can also read more about keeping related structures in good shape in our guide to how much a garage door costs to repair.
Can a metal carport withstand snow and high winds?
Branded and certified carports are engineered for specific snow and wind loads when you specify your region at purchase. A vertical roof and 12-gauge framing handle heavy snow far better than a horizontal-roof unit, so tell the builder your local codes and climate up front.
The Bottom Line
How much is a metal carport cost? Plan on $2,000 to $9,000 for a standard installed unit, with small kits starting around $1,200 and large or enclosed custom builds running well into five figures. The three levers that move the number most are size, whether you choose a kit or full installation, and the steel gauge and roof style you pick.
Get three written quotes, confirm what each one includes in writing (anchors, trim, delivery, and any permit or site-prep work), and compare them apples to apples rather than on sticker price alone.
