20×30 is the most-quoted carport size we sell. It fits two full-size vehicles, a truck plus a boat, or an RV with a workshop bay alongside it. Pricing in 2026 sits in a fairly tight band — but the spread between the lowest and highest configuration is wider than most buyers expect. Here's the real breakdown.
The short answer
- Open regular-roof, 14-gauge frame: $2,495–$3,295
- Open A-frame horizontal roof: $2,995–$3,895
- Open vertical-roof A-frame: $3,395–$4,295
- Partially enclosed (1 or 2 sides): $3,895–$5,195
- Fully enclosed (4 sides + walk-door + garage door): $5,295–$6,995
All prices include free delivery and installation in 48 states and a 10-year limited warranty. Pricing varies modestly by region; states with very high snow load or coastal salt exposure trigger upgrades.
What drives the price
Roof style (the single biggest swing)
Regular roof uses horizontal panels with rounded corners — the cheapest option and fine for mild climates. A-frame horizontal uses gabled framing with horizontal panels and is recommended for moderate snow. A-frame vertical runs the panels vertically from peak to eave so snow, leaves, and rain slide off cleanly — required by most manufacturers for any unit over 31 ft long or in heavy snow zones. Expect about $200–$1,000 between roof styles on a 20×30.
Gauge of the steel frame
Standard 14-gauge tubular is the default. 12-gauge tubular is a $200–$450 upgrade and gets you a heavier wall, longer warranty, and higher snow/wind ratings — worth it in storm country.
Eave height
Base eave is 6 ft. Each 1-ft height upgrade adds about $80–$150. For a 20×30 you'll typically want 8–10 ft if you're parking an SUV or boat, and 12 ft for an RV.
Enclosure
Adding wall panels is priced per linear foot. A single full side on a 20×30 adds roughly $400–$600. Two sides adds $800–$1,100. Full enclosure (all four sides plus end walls) typically adds $1,800–$2,800.
Doors and windows
- Standard 9×7 roll-up garage door: $395–$595
- 10×10 roll-up door: $595–$895
- Steel walk-in door (36"): $295–$495
- Window (30×30 sliding): $195–$295
Anchors and surface
Free anchors are included for concrete (wedge anchors), asphalt (asphalt anchors), and dirt/gravel (rebar or mobile-home anchors). Concrete is recommended for any enclosed configuration. A 600 sq ft slab for the 20×30 footprint typically runs $3,000–$5,000 separately.
What the final number looks like
See the full lineup on our carports page. Most 20×30 buyers in 2026 are landing around $3,600 for an open carport with horizontal panels and 8-ft walls, or $5,800 for a fully enclosed garage with one roll-up door, one walk-in door, and 10-ft walls. Add a slab and you're at $6,600 / $9,500 respectively, all-in, ready to use.
Lead time
Most 20×30 units ship and install in 2–4 weeks from order. Custom colors and higher-snow upgrades add 1–2 weeks. The installation crew typically completes a 20×30 in a single day.

- Boat + truck combined cover (A-frame vertical, 10-ft walls)
- One-vehicle enclosed garage + workshop bay alongside (fully enclosed with internal partition)
- Light-equipment storage for a small farm or contractor
