Double Carport Cost: Price Ranges, Materials, and Installation Factors 2026
The cost of a double carport typically ranges from affordable to mid-range depending on materials, size, and site work. Key drivers include roof type, framing material, foundation needs, labor rates, and local permitting. This article provides practical pricing in USD, with low, average, and high ranges and per-unit details to help buyers budget accurately for a two-car shelter that covers standard vehicle footprints.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Double carport installed | $4,500 | $8,000 | $15,000 | Assumes typical 20′ x 20′ to 24′ x 24′ footprint, standard materials |
| Per square foot estimate | $18 | $40 | $70 | Includes framing, roof, and basic finish |
| Materials only (pre-cut) | $2,500 | $5,500 | $10,000 | Excludes labor and site prep |
| Labor only (installation) | $1,500 | $2,800 | $5,000 | Typical crew and duration |
| Permits and inspections | $200 | $800 | $2,000 | Depends on city and scope |
Cost Snapshot: Typical price ranges for a double carport
Average price for a standard 20′ x 20′ double carport sits around $6,000 to $9,000, with low-end kits or simple structures around $4,500 and high-end custom builds near $15,000. Assumptions: Midwest labor rates, standard welded steel or wood framing, metal or asphalt roof, slab or compact gravel base.
| Size | Low | Average | High | Notes |
|---|---|---|---|---|
| 20′ x 20′ | $4,500 | $7,500 | $12,000 | Most common footprint for two cars |
| 24′ x 24′ | $5,500 | $9,000 | $15,000 | Additional shading and cover area |
| 30′ x 20′ | $6,000 | $10,500 | $18,000 | Higher roof line or posts required |
Materials That Drive the Price: roof, posts, and framing choices
The main material choices impact both upfront cost and durability. A basic metal roof on steel or aluminum framing may cost less than a premium wood frame with a live edge beam, but weather resistance varies. Perimeter posts and header size affect foundation needs and labor time, while a color-matched roof finish can add modestly to the total.
| Material Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Roof type | $1,800 | $3,500 | $7,000 | Metal sheet or panel roof common choice |
| Framing (steel vs wood) | $1,600 | $3,000 | $6,000 | Steel tends to cost more upfront but longer life |
| Posts and footings | $600 | $1,800 | $4,000 | Concrete footings add cost but improve stability |
| Finish and trim | $200 | $700 | $2,000 | Paint, coatings, and guttering |
Labor and Installation: crew size, time, and rates
Labor scales with project complexity, access, and local wage levels. A typical crew for a 20′ x 20′ double carport might run 1–3 days, with a rate range of $75–$125 per hour per worker. Total labor often represents 25–40% of overall cost, depending on site conditions and structural requirements.
| Labor Element | Low | Average | High | Notes |
|---|---|---|---|---|
| Installation crew (hours) | 12 | 40 | 60 | Depends on foundation and roof complexity |
| Hourly rate | $75 | $100 | $125 | Regional variation |
| Site preparation | $250 | $1,000 | $2,500 | Grading, debris removal |
Regional Variations: how geography changes price
Prices shift by city, climate, and permit stringency. In sunbelt regions with high steel demand, material costs may trend higher, while rural markets can offer lower labor. Region-adjusted quotes often show a 5–20% delta between coastal metros and inland areas.
| Region | Low | Average | High | Notes |
|---|---|---|---|---|
| Central U.S. suburbs | $5,500 | $9,000 | $14,000 | Balanced pricing |
| Coastal cities | $6,500 | $11,000 | $17,000 | Higher permits and labor |
| Rural towns | $4,500 | $7,500 | $12,000 | Often lower labor costs |
Foundation and Footings: concrete, slab, or gravel
A solid base prevents movement and reduces maintenance, but adds cost. A simple gravel base is cheaper, while a concrete slab or slab-on-grade raises both durability and price. Typical footing costs range from $600 to $2,600 depending on depth and access.
| Foundation Type | Low | Average | High | Notes |
|---|---|---|---|---|
| Gravel base | $200 | $600 | $1,200 | Least invasive |
| Concrete slab | $1,000 | $2,000 | $3,500 | Greater durability |
| Footings with rebar | $1,200 | $2,000 | $4,000 | Best stability in wind-prone areas |
Permits and Inspections: local rules and fees
Permitting is a real cost driver in many jurisdictions. Permit fees, plan reviews, and inspections can add 5–15% to the project or more in tight regulatory areas. Expect potential delays and fees if the project requires zoning variances or structural changes.
| Permitting Cost | Low | Average | High | Notes |
|---|---|---|---|---|
| Residential permit | $100 | $500 | $1,500 | Depends on municipality |
| Plan review | $0 | $200 | $800 | Often waived for simple structures |
| Impact or driveway permit | $0 | $100 | $700 | Site-specific |
Upgrade Options and Add-Ons: gutters, lighting, storage
Add-ons improve utility and longevity but add cost. A basic trim package, guttering, and exterior lighting can push costs by several hundred dollars, while built-in storage alcoves or a side wall enclosure can add thousands. Each accessory elevates price per foot of coverage.
| Add-On | Low | Average | High | Notes |
|---|---|---|---|---|
| Gutters and trim | $150 | $450 | $1,200 | Drip-edge and downspouts |
| Exterior lighting | $250 | $800 | $1,600 | LED fixtures, switches |
| Storage alcove or cabinets | $300 | $1,000 | $3,000 | Built-ins or freestanding |
Compare Enclosure vs Open Double Carport: price deltas
Choosing to close one or more sides or wrap the structure with panels raises material and labor needs. An open double carport may sit at the lower end of the range, while a fully enclosed shelter with siding, doors, and insulation can push the price upward by 25–45%. Assess whether enclosure matches climate and use.
Ways to Reduce Price Without Sacrificing Safety
Smart scope management can trim costs without compromising function. Options include standard dimensions, simplified roofline, limited color options, and scheduling installation during off-peak periods. Bundle quotes from multiple contractors to compare base price against a finished plan, and consider repairing or upgrading existing structures instead of full replacement when feasible.
Practical Quote Structure: what to ask for
A well-structured quote should present major components clearly: materials, labor, foundation, permits, delivery, and optional add-ons. Compare totals with and without foundation, and request per-square-foot or per-carport unit pricing to normalize bids. Request a breakdown to validate totals.
Real-World Quote Scenarios
Examples help anchor expectations. Scenario A shows a mid-range wood-framed double carport with a concrete slab and basic gutters; Scenario B adds steel framing and a standing seam roof; Scenario C focuses on a compact 18′ x 20′ unit in a rural region with gravel base. Use these benchmarks to spot inflated bids.

|---|---|---|---|---|---|---|---|
| A | 20′ x 20′ | Wood frame, metal roof | Gravel | Metal | $2,800 | $7,500 | Balanced option |
| B | 24′ x 24′ | Steel frame, standing seam | Slab | Stand seam | $3,600 | $12,000 | Higher durability |
| C | 18′ x 20′ | Wood frame, basic metal roof | Gravel | Metal | $2,100 | $6,000 | Rural region pricing |
