Quick Answer

A two-car metal carport is a prefabricated steel or aluminum open-sided shelter designed to protect two vehicles from weather. Prices typically range from $1,500 to $6,000 installed, depending on size, gauge, and local labor costs. Most homeowners can assemble a basic kit themselves, but permits, anchoring, and local wind or snow load requirements vary significantly by location.

Key Takeaways

  • A standard two-car metal carport measures 20 feet wide by 20 feet deep, though 24×24 is recommended for comfortable clearance
  • Installed costs typically run $1,500 to $6,000; a comparable attached garage costs $15,000 to $50,000 or more
  • Galvanized or Galvalume-coated steel resists rust effectively and can last 20 to 40 years with basic maintenance
  • Most jurisdictions require a building permit; skipping this step can result in fines or mandatory removal
  • Proper anchoring (concrete footings or ground anchors) is the single most critical factor for wind resistance
  • DIY assembly is feasible for two adults in one to two days using a bolt-together kit
  • Metal carports can accommodate RVs and boats with the right height and width upgrades
  • Common buying mistakes include underestimating size needs, ignoring local load ratings, and choosing the cheapest gauge steel

What Exactly Is a 2 Car Metal Carport?

A two-car metal carport is a freestanding or attached open-sided structure built from steel or aluminum tubing and sheet metal roofing, designed to shelter two vehicles side by side. Unlike a garage, it has no enclosed walls, which keeps costs low and assembly fast.

These structures come in three common roof styles:

  • Regular (rounded) roof: The most affordable option, with horizontal panels that shed light rain but struggle under heavy snow loads
  • A-frame (boxed eave) roof: Vertical panels on the roof face, better for moderate snow and rain
  • Vertical roof: Panels run top to bottom, allowing snow and debris to slide off easily; recommended for high-precipitation climates

Most kits arrive pre-cut and pre-drilled. The buyer selects gauge (thickness), height, width, and add-ons such as side panels, gable ends, or gutters. The result is a customizable shelter that costs far less than a traditional garage.

How Much Does a Typical 2 Car Metal Carport Cost?

The installed price for a two-car metal carport in 2026 generally falls between $1,500 and $6,000, with the wide range driven by size, steel gauge, roof style, and regional labor rates.

Here is a general cost breakdown:

Configuration Estimated Cost (Installed)
Basic 18×20, regular roof, 14-gauge $1,500 – $2,200
Standard 20×20, A-frame, 12-gauge $2,500 – $3,500
Heavy-duty 24×24, vertical roof, 12-gauge $3,800 – $6,000
DIY kit only (no installation) $900 – $3,000

Factors that raise the price:

  • Thicker steel gauge (12-gauge costs more than 14-gauge but is stronger)
  • Vertical roof style adds $200 to $500 over a regular roof
  • Enclosed side panels add $300 to $800 per side
  • Concrete anchoring and site preparation vary by region

Choose a basic kit if your climate is mild and you only need rain and UV protection. Choose a heavy-duty vertical-roof unit if you live in a snow belt or high-wind zone.

Metal Carport vs. Garage: Which Is Cheaper?

A metal carport is substantially cheaper than a garage in almost every scenario. A two-car attached garage typically costs $15,000 to $50,000 to build (per HomeAdvisor and similar cost-tracking sources), while a two-car metal carport runs $1,500 to $6,000 installed.

When a metal carport makes more sense:

  • Budget is the primary concern
  • You need a temporary or semi-permanent structure
  • The property is rented or the owner plans to sell soon
  • Zoning prohibits a full garage addition

When a garage is worth the investment:

  • You need secure, enclosed storage
  • You want to add permanent value to the property
  • You live in a climate with extreme cold, requiring insulated space
  • You plan to use the space as a workshop

A metal carport does not add the same resale value as a garage, but it also does not require the same foundation, permitting complexity, or construction timeline. For pure vehicle protection at the lowest cost, a metal carport wins clearly.

What Size Do I Need for Two Cars?

The minimum recommended size for two cars is 20 feet wide by 20 feet deep, but a 24×24 footprint provides noticeably better comfort for opening doors and moving around vehicles.

Standard car dimensions run roughly 6 feet wide by 16 feet long. Two cars side by side need at least 14 feet of width, but door swing, mirrors, and walking space push the practical minimum to 20 feet. Trucks, SUVs, and minivans benefit from a 24-foot or wider span.

Height considerations:

  • Standard leg height is 6 feet, which clears most sedans and SUVs
  • Trucks with roof racks or camper shells often need 8-foot legs
  • RV storage requires 12 to 16 feet of clearance (see the RV section below)

A quick rule: measure your two widest vehicles side by side, add at least 5 feet for door clearance on each side, and that is your minimum width. Then add 2 feet to the length of your longest vehicle for the depth.

2 Car Metal Carports FAQ’s: Are They Good in Snow and Wind?

A properly rated and anchored metal carport handles snow and wind well, but only if you buy the right specifications for your climate. A cheap regular-roof unit with light-gauge steel is not appropriate for heavy snow regions.

Snow load: Look for a carport rated to your local ground snow load (measured in pounds per square foot, or PSF). The International Building Code provides maps showing required snow loads by region. A vertical-roof carport with 12-gauge steel typically carries a higher snow load rating than a regular-roof unit.

Wind resistance: Most quality carports are rated for 90 to 140 mph wind speeds when properly anchored. The anchoring method matters as much as the frame rating. A carport bolted to a concrete slab outperforms one with mobile-home-style ground anchors in high-wind conditions.

Practical tips for harsh climates:

  • Order a vertical roof (not regular) in any area with more than 20 inches of annual snowfall
  • Specify 12-gauge steel over 14-gauge for added rigidity
  • Ask the manufacturer for the certified load ratings in writing before purchasing
  • Clear heavy snow accumulation promptly; even rated structures benefit from reduced load

Do Metal Carports Rust Over Time?

Modern metal carports resist rust effectively because they use galvanized or Galvalume-coated steel, which bonds a zinc or zinc-aluminum alloy layer to the steel surface. Under normal conditions, a quality carport will not show significant rust for 15 to 25 years.

What accelerates corrosion:

  • Scratches or cuts in the coating that expose bare steel
  • Coastal environments with salt air
  • Standing water on flat or low-slope roofs
  • Dissimilar metals in contact (for example, aluminum fasteners against steel panels)

How to slow it down:

  • Touch up any scratches with zinc-rich primer or cold galvanizing compound
  • Keep gutters and drainage clear so water does not pool
  • Inspect fasteners annually; replace any that show rust spots
  • In coastal areas, ask for a higher-grade coating or stainless steel hardware

Aluminum carports are naturally rust-proof but are generally less rigid than steel for the same cost. For most inland climates, galvanized steel is the better value.

Do Metal Carports Rust Over Time?

How Long Do Metal Carports Usually Last?

A well-built, properly anchored metal carport lasts 20 to 40 years under typical residential conditions. Some manufacturers offer 20-year or longer warranties on the frame, though roofing panels and fasteners may need replacement sooner.

Longevity depends on three factors: steel quality, anchoring, and maintenance. A 12-gauge galvanized frame with a vertical roof in a dry inland climate will outlast a 14-gauge regular-roof unit in a coastal or high-snow environment by a wide margin.

Routine maintenance that extends lifespan:

  • Annual inspection of all bolts and connections (tighten any that have loosened)
  • Touch-up paint or sealant on any exposed metal
  • Clear debris from the roof and gutters after storms
  • Check anchor points for erosion or movement

What Permits Do I Need to Build a Metal Carport?

Most jurisdictions require a building permit for a permanent metal carport, and some also require a zoning variance or HOA approval. Skipping the permit process is one of the most common and costly mistakes buyers make.

Typical permit requirements:

  • Building permit (structural review, especially for wind and snow loads)
  • Zoning approval (setback requirements from property lines and the home)
  • HOA approval if applicable (some associations prohibit visible carports)
  • Electrical permit if lighting or outlets are added

How to find out what you need:

  1. Contact your local building department before purchasing
  2. Ask specifically about setback distances and maximum structure height
  3. Find out if an engineered drawing is required (some counties require a stamped engineer’s plan for structures over a certain square footage)
  4. Submit permit applications before ordering the carport, as approval can take two to six weeks

Unpermitted structures can result in fines, mandatory removal, or complications when selling the property. The permit fee is usually $50 to $300 and is worth the protection.

Are Metal Carports Good for RV and Boat Storage?

Yes, metal carports are widely used for RV and boat storage, but standard two-car dimensions are not sufficient. RV and boat storage requires custom height and width specifications.

Typical clearance needed:

  • Class A motorhomes: 13 to 14 feet tall, 8 to 8.5 feet wide
  • Fifth-wheel trailers: 12 to 13 feet tall
  • Pontoon boats on trailers: 10 to 12 feet tall
  • Bass boats on trailers: 8 to 10 feet tall

A standard two-car carport (6 to 8-foot legs) will not clear most RVs. Manufacturers offer leg heights up to 16 feet and widths up to 40 feet for RV-specific configurations. If you plan to store an RV or large boat alongside two cars, order a wider structure with taller legs and price it as a custom unit.

2 Car Metal Carports FAQ’s: Common Mistakes People Make When Buying

The most frequent and expensive mistakes in buying a two-car metal carport are choosing the wrong size, ignoring local load requirements, and skipping the permit process.

Mistake 1: Buying too small. Many buyers order a 18×20 unit and discover their trucks or SUVs barely fit. Measure first, then add buffer space.

Mistake 2: Choosing the cheapest gauge. A 14-gauge regular-roof carport costs less upfront but may fail under heavy snow or wind. The cost difference between 14-gauge and 12-gauge is usually $300 to $600, far less than a replacement.

Mistake 3: Ignoring local codes. Buying and installing without a permit can result in removal orders.

Mistake 4: Poor site preparation. Installing on uneven or soft ground leads to frame distortion and anchor failure.

Mistake 5: Skipping professional anchoring. Ground anchors alone are not adequate in high-wind zones. Concrete footings or a full concrete slab provide substantially better stability.

How to Anchor a Metal Carport Securely

Proper anchoring is the most critical installation step and the one most often done poorly. A carport that is not anchored correctly can become a projectile in a severe storm.

Three main anchoring methods:

  1. Concrete slab: The strongest option. The carport legs bolt directly to anchor bolts set in a poured concrete slab. Recommended for permanent installations and high-wind zones.
  2. Concrete footings (piers): Individual concrete piers are poured at each leg location. Less material than a full slab but nearly as strong for wind resistance.
  3. Ground anchors (mobile-home style): Auger-style anchors driven into the ground. Acceptable for mild climates and temporary use, but not recommended for areas with high wind or frost heave.

Step-by-step anchoring checklist:

  • Call 811 (in the US) to have underground utilities marked before digging
  • Dig or drill to below the local frost line for concrete footings
  • Use anchor bolts specified by the manufacturer, not substitutes
  • Allow concrete to cure fully (typically 24 to 48 hours minimum) before attaching the frame
  • Torque all leg bolts to the manufacturer’s specification
  • Inspect anchors after the first major storm season

Best Brands for Metal Carports in 2026

Several manufacturers have established strong reputations for quality, warranty support, and dealer networks. The following brands are frequently cited by contractors and buyers for consistent quality as of 2026:

  • Carolina Carports: Wide customization options, strong dealer network across the southeastern and central US, vertical roof options standard
  • Alan’s Factory Outlet: Competitive pricing, online configurator, ships nationwide
  • Arrow Storage Products: Widely available through home improvement retailers, good for basic DIY kits
  • General Steel: Heavier commercial-grade options, better for large or custom configurations
  • Absolute Steel: Known for thicker gauge options and longer warranty terms

When evaluating any brand, ask for the certified wind and snow load ratings in writing, confirm the warranty covers both frame and panels, and check that local dealers can provide installation and post-sale support.

FAQ

Q: Can I install a 2 car metal carport by myself?
Yes. Most bolt-together kits are designed for two adults with basic tools. Expect one to two days for a standard 20×20 unit. Concrete work and anchoring may require additional help or equipment.

Q: Do I need a concrete slab for a metal carport?
Not always. Ground anchors work in mild climates, but a concrete slab or footings are strongly recommended in high-wind or high-snow regions and for permanent installations.

Q: How much wind can a metal carport withstand?
Quality carports are rated for 90 to 140 mph winds when properly anchored. Always check the manufacturer’s certified wind rating for your specific model.

Q: Will a metal carport add value to my home?
A metal carport adds modest functional value but does not increase appraised home value the way a permanent garage does. It may help sell the property faster by offering covered parking.

Q: How long does it take to install a 2 car metal carport?
A professional crew typically installs a standard unit in four to eight hours. A DIY installation usually takes one to two full days.

Q: Can I enclose a metal carport to make it a garage?
Yes. Most manufacturers sell side panels, gable ends, and roll-up doors as add-ons. A fully enclosed metal carport functions similarly to a metal garage, though it may require additional permits.

Q: What is the difference between 12-gauge and 14-gauge steel?
Lower gauge numbers indicate thicker steel. 12-gauge steel is thicker and stronger than 14-gauge. For two-car carports in areas with significant snow or wind, 12-gauge is the better choice.

Q: Do metal carports require maintenance?
Minimal maintenance is needed. Annual bolt tightening, scratch touch-up, and debris clearing from the roof are sufficient for most units.

Q: Can a metal carport be moved after installation?
Yes, if anchored with ground anchors rather than concrete. Concrete-anchored units are effectively permanent.

Q: Are metal carports allowed in all residential areas?
No. Some municipalities, HOAs, and zoning districts restrict or prohibit visible carports. Always check local rules before purchasing.

Conclusion

The 2 car metal carports FAQ’s covered in this guide address the questions that matter most before making a purchase: size, cost, durability, permits, anchoring, and brand selection. The core takeaway is that a two-car metal carport is one of the most cost-effective vehicle shelter options available, but its performance depends entirely on buying the right specifications for your climate and installing it correctly.

Actionable next steps:

  1. Measure your two vehicles and calculate the minimum footprint you need, then add at least 5 feet of width for door clearance
  2. Contact your local building department to confirm permit requirements and setback rules before ordering
  3. Decide on your anchoring method based on your climate and whether the structure is permanent or temporary
  4. Request certified load ratings from at least two manufacturers and compare them against your local snow and wind requirements
  5. Get at least two installation quotes if you are not doing the work yourself

A well-chosen, properly anchored metal carport will protect your vehicles reliably for two decades or more. The research you do before buying is the most valuable investment you can make in the process.
