A double carport typically costs $4,000-$18,000 installed, with many standard two-car projects averaging about $9,000. The final price depends on dimensions, steel or wood construction, roof style, foundation, local wind requirements, site preparation, and labor rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed double carport | $4,000 | $9,000 | $18,000 | Typical 20-by-20- to 24-by-24-foot project |
| Basic steel kit | $2,000 | $4,500 | $8,000 | Materials only, before site work and installation |
| Installed cost per square foot | $8 | $18 | $35 | Varies with material, roof, and foundation |
| Concrete slab | $6 per sq ft | $9 per sq ft | $14 per sq ft | May exclude excavation or difficult access |
| Installation labor | $800 | $2,500 | $5,000 | Higher for custom framing or complex sites |
What a Double Carport Costs by Size and Build
A basic prefabricated steel carport for two vehicles often costs $4,000-$7,500 installed, assuming a level site, standard roof, ordinary access, and anchoring to an existing suitable surface. A midrange project with a concrete pad, stronger framing, or a larger footprint commonly totals $7,500-$12,000. Custom wood structures, enclosed storage, premium roofing, or substantial site work can bring the total to $12,000-$18,000 or more.
Typical double-car dimensions range from 20 by 20 feet to 24 by 24 feet. A 20-by-20-foot footprint covers 400 square feet, while a 24-by-24-foot design covers 576 square feet. Installed prices often work out to about $8-$35 per square foot, but the rate is not a simple materials calculation: foundations, permits, delivery, and minimum installation charges can weigh more heavily on smaller projects.
For a standard 20-by-22-foot steel carport with a straightforward installation, a practical starting budget is about $6,000-$10,000. Costs above that range usually reflect upgrades, custom dimensions, expensive local labor, or site and code requirements.
Assumptions: U.S. pricing for a freestanding, open-sided carport with ordinary access; regional labor and permit fees vary.
How Steel, Wood, and Site Work Shape the Quote
Material and installation charges should be separated when reviewing estimates. A kit price may not include delivery, anchoring, a slab, equipment rental, permits, or assembly. A contractor’s installed quote may include some or all of these items, so two apparently different prices may cover different scopes.
| Quote component | Typical price range | What can raise it |
|---|---|---|
| Steel frame and roof kit | $2,000-$8,000 | Thicker framing, larger span, coating, engineered wind rating |
| Wood framing and roofing materials | $4,000-$10,000 | Premium lumber, decorative trim, shingles, custom design |
| Assembly labor | $800-$5,000 | Custom work, difficult access, extra bracing, crew size |
| Concrete slab or footings | $2,400-$8,000 | Thicker slab, reinforcement, excavation, drainage needs |
| Delivery and disposal | $150-$1,200 | Long haul, equipment access, packaging or old-structure removal |
| Permits and inspections | $100-$1,000 | Local application fees, engineered plans, inspection requirements |
A concrete slab for a 20-by-22-foot carport covers 440 square feet. At roughly $6-$14 per square foot, the concrete work could be $2,640-$6,160 before unusual excavation or grading. Some installations instead use concrete footings or ground anchors, which can reduce the upfront cost where local rules and soil conditions allow.
Check whether the estimate includes the foundation, anchoring, delivery, and permit handling before comparing its bottom line.
How Width, Roof Design, and Wind Rating Change Price
Footprint is one of the clearest cost drivers. Moving from a 20-by-20-foot model to a 24-by-24-foot model adds 44% more covered area, and the frame, roofing, foundation, and labor may rise accordingly. Extra height for a tall van or truck can also require longer posts, additional bracing, or a stronger engineered structure.
Roof shape affects both material quantity and performance. A basic regular roof is generally the least expensive choice. A boxed-eave or horizontal-panel roof may add roughly $300-$1,500, depending on the kit and dimensions. A vertical-panel roof, which directs water and debris along the roof slope, can add about $500-$2,000 over a basic design. Snow-load specifications, steep pitch, and roof drainage details can increase the quote further.
Wind ratings and snow loads matter where local building codes require them. A reinforced carport designed for higher wind exposure may cost $500-$3,000 more than a basic configuration; engineered plans or special anchoring can add more. A structure rated for 30 pounds per square foot of snow load may not meet requirements in an area that calls for 50 pounds per square foot or higher. The installer should confirm that the selected model meets local design requirements rather than relying on a generic kit description.
Foundation needs depend on soil, slope, and the selected support system. A nearly level, stable site may need only standard anchors or modest footings. Sloped ground, loose soil, or a large height difference can require grading, retaining work, longer posts, or custom foundation details. Confirm the exact footprint, height, roof style, and required wind or snow rating before accepting a kit price.
What Installation Labor Adds to a Two-Car Carport
Professional assembly commonly takes a crew of two to four people about 8-20 hours for a straightforward steel structure. With typical labor rates of $50-$100 per worker-hour, assembly labor can fall between $800 and $4,000, although some contractors quote a fixed installation fee. Custom wood construction may take several days and cost $2,500-$7,000 in labor, depending on framing, roofing, and finish work.
Slab installation is usually a separate trade and schedule. A concrete crew may spend 1-3 days on layout, preparation, pouring, and cleanup, followed by curing time before the carport can be anchored. The actual calendar time can stretch to one or two weeks if excavation, weather delays, inspections, or concrete scheduling are involved.
Hourly pricing can help explain an estimate, but it should not be treated as the sole measure of value. A fixed quote may account for travel, tools, insurance, setup, and return visits. Ask whether the labor charge includes assembly, bracing, anchoring, cleanup, and coordination with the concrete contractor. Request a written scope that identifies both labor tasks and the number of workers or workdays included.
Regional Prices from Rural Lots to City Properties
Regional pricing varies with labor markets, permitting, freight distance, climate requirements, and contractor availability. Relative to a typical national quote, projects in lower-cost rural areas may run about 5%-15% below average when the site is accessible and no special engineering is required. Major metro areas and high-cost coastal markets may run 10%-25% above a comparable baseline, especially when labor, inspections, or delivery are expensive.
Snow-belt locations can require stronger roof framing and higher snow-load ratings; those specifications may add roughly 5%-20% to the structure price. Coastal or storm-prone areas may need enhanced anchoring, corrosion-resistant finishes, or engineered wind resistance, sometimes adding 5%-20% or more. These are planning ranges, not fixed regional multipliers: local code, terrain, and product availability can change the actual quote.
Freight costs deserve attention when the kit ships from outside the region. Delivery can add $150-$1,200 for a standard shipment, with remote access, long-distance hauling, or specialized unloading costing more. Urban sites may have higher labor rates and limited truck access, while rural properties may face longer travel charges or fewer available installers. Compare local quotes that specify the same dimensions, load rating, foundation, and delivery terms.
Which Carport Add-Ons Increase the Installed Price
Side panels, partial walls, gutters, lighting, storage areas, and vehicle-height upgrades can turn an open shelter into a more substantial project. A single side panel may add about $300-$1,000; enclosing one or more sides can add $1,000-$4,000 or more, depending on material and openings. Gutters and downspouts often add $300-$1,200, while basic electrical work for lighting may cost $500-$2,000 when a new circuit or trenching is needed.
Site preparation can create a larger unplanned expense than small accessories. Clearing vegetation may cost $200-$1,500, grading can run $500-$3,000, and removing an old carport may cost $300-$2,000, depending on size, disposal, and whether the existing slab stays. Extensive earthwork or drainage correction can exceed these ranges. Ask the contractor to inspect the site before treating a kit price as a complete project estimate.
Permit fees and inspections are local. A simple permit may cost $100-$500, while engineered plans, inspections, or more demanding applications can bring the total to $1,000 or more. Some jurisdictions require a permit based on the structure’s area, attachment, or intended use. Price required code work and necessary drainage before adding optional walls or finishes.
Three Double Carport Quotes With Different Scopes
The examples below illustrate how scope changes the total. They are planning scenarios rather than guaranteed market offers; local labor, delivery, and code rules affect each estimate.
| Project | Materials and size | Labor and site work | Estimated total |
|---|---|---|---|
| Basic rural steel | 20-by-20 feet, regular roof, $3,200-$4,500 kit | 10-12 labor hours, anchors, $400-$1,000 delivery | $4,800-$7,000 |
| Midrange suburban build | 22-by-24 feet, vertical roof, reinforced steel, $5,000-$7,500 materials | 16-20 labor hours, $3,000-$4,500 slab, permit and delivery | $9,000-$13,500 |
| Custom wood structure | 24-by-24 feet, shingle roof, upgraded trim, $7,000-$11,000 materials | Several days of carpentry, footings or slab, engineering and finish work | $14,000-$22,000 |
For the basic example, an existing level concrete pad can reduce the total if it is in good condition and accepts the specified anchors. The midrange quote assumes new concrete and stronger steel components, while the custom example includes more labor-intensive construction and finishes. A quote above the example range may still be reasonable if it includes substantial grading, an engineered foundation, or unusually high design loads.
Use each quote as a scope comparison, not simply as a price-per-car comparison. The useful comparison is the installed cost for the same size, material, roof, foundation, load rating, and included services.
How to Lower the Price Without Cutting Required Strength
Choose the smallest footprint that safely fits both vehicles, allows door opening, and leaves room for practical movement around them. A 20-by-20-foot structure may suit two compact cars, while larger vehicles or wider parking spaces may call for 22-by-24 or 24-by-24 feet. Confirm measurements before ordering: increasing the footprint later can be more expensive than choosing the right dimensions at the start.
Keep the design simple where conditions permit. A standard steel kit with a regular roof and no decorative trim generally costs less than custom wood framing or premium finishes. Avoid paying for a snow or wind rating beyond local requirements, but do not reduce anchoring or structural strength below code. Ask the seller or installer to document the applicable rating for the property.
Get at least three itemized quotes with matching specifications. Compare kit price, installation, concrete, permits, delivery, disposal, and warranty rather than relying on a single total. Ask whether a slab is required, whether existing pavement can be used, and whether the installer can bundle delivery or foundation work without reducing the stated scope.
Prepare the site only when the work is clear and appropriate. Removing small obstructions or arranging access may reduce crew time, but grading, excavation, and concrete work should follow the required dimensions and drainage plan. The largest reliable savings usually come from controlling size, avoiding unnecessary upgrades, and comparing complete installed quotes.
