Prices for a double carport vary by size, materials, labor, and local permitting. This guide presents real-world cost ranges in USD and highlights the main drivers behind the price of a two-vehicle covered parking structure.
Key takeaway: expect a multi-thousand-dollar range that reflects size, material quality, and site challenges.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Double carport kit (20×20 ft) | $8,000 | $12,000 | $18,000 | Frame, roof, basic hardware |
| Double carport kit (24×24 ft) | $12,000 | $18,000 | $28,000 | Increased coverage and rafters |
| Double carport kit (28×28 ft) | $16,000 | $24,000 | $38,000 | Larger footprint, more materials |
| Permits & inspections | $200 | $1,200 | $4,000 | Depends on jurisdiction |
| Delivery and site preparation | $600 | $2,000 | $5,000 | Grading, access, crane or equipment |
Assumptions: standard access, asphalt or concrete drive, Midwest labor rates, and basic weatherproof roof finish.
Size and Material Mix Directly Drive the Price Range
Largest factor: footprint size combined with chosen materials determines both material costs and installation effort. A 20×20 ft double carport is typically cheaper per square foot than a 28×28 ft structure due to fewer posts and less roof area. Material options like steel, aluminum, or wood framing create wide price gaps, with steel often the most durable but also the most expensive upfront.
Material Choices: Steel, Aluminum, or Wood for a Double Carport
Material choice affects longevity and price. Steel frames with steel roofing tend to cost more but last longer with low maintenance; aluminum offers corrosion resistance with mid-range pricing; wood provides a warm look and usually the lowest upfront cost but higher upkeep. Typical ranges per project: Steel frame $10,000-$22,000 for 20×20, Aluminum $9,000-$16,000, Wood $7,000-$14,000 for a 20×20 area. For larger 24×24 or 28×28 builds, add $2,000-$8,000 depending on finish and fasteners.
Labor and Installation: Typical Hours and Rates per Job
Labor cost hinges on crew size and local wage levels. A standard double carport install often requires 1-2 days with a small crew in straightforward conditions. Labor estimates: $75-$125 per hour or $2,500-$6,500 total for a typical 20×20 job. For larger footprints or challenging sites, expect higher labor hours and costs. Span example: with 16-40 labor hours depending on scope.
Regional Variations: Coastal, Inland, and Urban Pricing Premiums
Region shifts price by weather, code stringency, and labor availability. Coastal markets may add 5-15% due to corrosion-resistant materials and permitting complexity; urban areas can add 10-25% for higher dispatch costs and restricted work hours. Rural regions may see 0-10% savings. For a 24×24 carport, expect averages of $16,000-$22,000 in urban coastal zones versus $14,000-$20,000 inland.
Per-Unit Breakdown: Posts, Rafters, Roof Panels, and Fasteners
Understanding the components helps compare quotes accurately. A typical 20×20 double carport uses 6-8 posts, rafters, purlins, and a roof panel system. Materials cost can range from $4,000-$8,000 for the frame and $3,000-$6,000 for roof components, with fasteners and trim adding $500-$1,500. See table for a practical breakdown by footprint:
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Posts and frame (steel or aluminum) | $3,000 | $5,000 | $9,000 | Depends on material |
| Rafters and roofing panels | $2,000 | $3,500 | $6,000 | Includes fasteners |
| Fasteners, trim, sealants | $300 | $1,000 | $2,000 | Corrosion-resistant options cost more |
| Foundation or footing work | $500 | $1,500 | $3,000 | Pad or slab may be required |
Permits, Inspections, and Codes: Potential Fees
Permitting adds both time and money to the project. Some jurisdictions require structural permit, electrical clearances, or setbacks review. Typical permit costs: $200-$2,500, with inspections adding $100-$1,500. In regions with strict stormwater or drainage requirements, budget higher for compliance-related work.
Project Scope Scenarios: 20×20, 24×24, and 28×28 Carports
Size tiers align with vehicle counts and future storage needs. A 20×20 carport comfortably covers two compact cars; 24×24 offers more maneuvering space; 28×28 supports larger pickups or additional storage. Concrete pad options (if needed) can add $4,000-$8,000 for a 20×20 footprint and scale up with size. For a full metal roof, expect higher material costs but longer life compared to asphalt shingles.
Cost-Saving Strategies: How to Reduce the Price Without Sacrificing Quality
Smart choices lower price without sacrificing protection. Compare quotes from at least two installers, choose standard materials with no specialized coatings, and plan for off-peak scheduling to reduce labor surcharges. Consider using a prefabricated kit with local assembly rather than a custom build, and align the project scope to include only essential features initially. Bundling demolition or site prep with the same contractor can yield a modest discount.
Cost-Driven Add-Ons and Substitutions to Consider
Some add-ons significantly impact price. Optional features such as decorative post caps, insulated roofing, rain gutters, or integrated lighting add cost but may improve functionality. If a regional climate requires color-matched coatings or enhanced wind resistance, expect a 5-20% premium depending on the material and design.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Standard steel frame, basic roof | $8,000 | $12,000 | $18,000 | Baseline configuration |
| Premium coating or corrosion protection | $500 | $2,000 | $4,000 | Regional needs may rise |
| Site prep and drainage improvements | $1,000 | $2,500 | $5,500 | Soil and slope influence |
