The average carport costs $6,223, ranging from as low as $300 to over $25,000 for custom builds. Carport cost depends on factors like location, size, and the quality of materials. Proper budgeting is essential to ensure you can cover materials and labor, and hiring a pro can guarantee a safe, long-lasting structure.
Several factors, including materials and labor, influence the final price of building a carport. Here's what you need to know to budget for your carport installation.
The size of your carport significantly affects the total cost. Whether you opt for a prefab unit or a custom build, standard sizes are available based on how many vehicles you need to shelter. Smaller carports for a single car will cost less than larger structures designed for multiple vehicles or RVs.
Dimensions | Cost (Installed) | Vehicle Capacity |
---|---|---|
21'L x 12'W x 6'H | $2,400–$8,400 | One car |
21'L x 24'W x 6'H | $4,000–$14,000 | Two cars |
41'L x 20'W x 12'H | $6,000–$21,000 | One RV |
Carports are available in metal, wood, and polycarbonate. Wood is the more common option for custom carports because it's the most affordable for unique builds. Metal is the most common for prefab units, followed closely by polycarbonate.
Material | Average Cost per Sq. Ft. |
---|---|
Metal | $20–$40 |
Polycarbonate | $12–$20 |
Wood | $15–$35 |
Metal carports cost between $15 and $30 per square foot, including labor. Custom metal carports can cost up to $40 per square foot. Most carport kits feature aluminum or steel frames, although you’ll also find options made from metal alloys or composites. Roof panels may be metal, polycarbonate, or even heavy-duty fabric.
Polycarbonate is the most affordable option overall, at $12 to $20 per square foot, installed. These units often have an aluminum frame and legs and a polycarbonate cover that lets light through by filtering out UV rays.
Wood carports range from $15 to $35 per square foot, including materials and labor. Wood carports often have complete walls on the sides and sometimes at the back end, too. Roof materials are often shingle or metal. Note that because wooden models often have walls, they consume more materials, so they cost more to install overall.
If labor isn’t rolled into the kit price, expect to pay $10 per square foot, with higher rates for intricate designs or premium finishes.
The cost of a concrete slab ranges from $4 to $8 per square foot. Since the average car needs 300 to 350 square feet of space, this means you’ll spend somewhere between $1,200 and $2,800 per car. Many carports are built on a concrete slab, which includes piers. Installation requires a qualified professional.
Slabs aren’t always desirable or possible for a carport, but garages require them. So, if you want to convert the carport into a full garage, pouring the slab will save you time and money later. Choose a level location for your slab, protected from wind, and convenient for parking your car.
Your municipality may have specific zoning requirements and permit fees. In many cases, permit costs range from $60 to $800 or more, so be sure to budget accordingly or consult with your contractor.
RV carports cost between $6,000 and $21,000 and measure at least 20 by 30 feet. Because these carports have to be taller and longer to accommodate the height and length of the average RV, they tend to be freestanding structures. Many people choose a carport for their RV because the cost to build a garage big enough to house an RV is comparatively prohibitive.
Custom carports give you the freedom to design a structure that complements your home's style, but they come with a higher price tag, costing up to $25,000 for elaborate designs.
Custom metal carports can cost up to $40 per square foot, including materials and labor. Because wooden carports include walls, you’ll spend more on the added materials and installation time.
Custom carports come with other expenses, too. Here are some extras that you might want to include in your carport project and their costs:
Electrical: If your custom carport requires electrical work, hiring an electrician adds $100 per hour to your expenses, depending on the installation requirements.
Site prep: Additional fees may apply for site preparation. Minor ground leveling might cost an average of $150.
Additions: Non-standard installations—like mounting a carport over another structure or on a boat dock—can add up to $200.
Location: If your site is more than 50 feet from the road, expect an extra $50 or so in labor charges.
Consider these cost-saving strategies to make your carport installation project more wallet-friendly:
Choose inexpensive materials like polycarbonate instead of higher-cost metal or wood.
Skip customizations and choose a simple prefab carport kit to trim costs.
Get at least three detailed quotes from local carport builders to ensure competitive pricing.
You might be tempted to build a basic carport yourself, but hiring a local handyperson or carport pro ensures the structure is safe, code-compliant, and built to last. While you'll save on labor if you do it yourself, building anything other than the most basic structure requires a lot of time and skill.
Mistakes can lead to weather damage or even structural collapse, posing risks to both you and your vehicle. It's best to leave tasks like electrical work or pouring a foundation to licensed contractors. Professional installation guarantees your carport is secure and compliant with local regulations. An experienced team can complete the installation in two days or less.

Enclosing a carport essentially turns it into a garage. You’ll start by framing and finishing exterior walls, then add a garage door (averaging $1,200), windows, and wiring for lights or outlets.
Plan for site prep and, if needed, a thicker slab to handle the added weight. Once the walls are up, insulation, drywall, and exterior siding create a secure, weather-tight space that protects vehicles and gear year-round.
A well-built carport may not add a huge dollar figure to an appraisal, but it can boost buyer appeal. Covered parking protects vehicles and lawn equipment, sharpens curb appeal, and fills what might otherwise be an empty driveway space. If the carport matches your home’s style and stays in good repair, it can make the property more attractive and competitive when you decide to sell.
Most cities and counties require a building permit for a new carport. Fees range from $60 to $800, depending on local codes and the size of the structure. Getting the permit upfront ensures the carport meets zoning rules and HOA guidelines, protecting you from fines or expensive retrofits later. Check with your building department—or ask your contractor—before ordering materials or scheduling installation.
A poured concrete slab is the gold standard for carport foundations. Concrete delivers superior load-bearing strength, keeps posts level, and resists shifting in freeze-thaw conditions. While gravel, dirt, or permeable pavers cost less upfront, they can’t match concrete’s long-term stability, especially if you might convert the carport into a garage later. Investing in a slab now can save money and hassle down the road.
Pre-made kits start at $300 and bundle all the required parts—sometimes installation, too—making them the most budget-friendly option. Custom carports cost more ($12 to $40 per square foot plus labor) but let you match the design, size, and finishes to your home.
If price and quick setup top your list, go with a kit. If you have a tricky layout or want a seamless aesthetic, investing in a custom build is worth the premium.
