24x30 Metal Carport: Prices, Specs & What Fits
A 24x30 carport covers 720 square feet. It is the two-vehicle size for people who drive full-size trucks and want room left over for a mower, a workbench, or storage at one end. Many builders list it as a 24x31 because the roof runs a foot past the 30-foot frame. This page covers what a 24x30 costs installed, what fits, and the options that change the price.

What Fits Under A 24x30 Carport?
The 24-foot width is what makes this size work for trucks. Two half-ton pickups are each close to 7 feet wide before mirrors, and 24 feet leaves about 3 feet in each gap to open doors, compared with about 2 feet under a 20x20. The 30-foot length covers long crew-cab pickups bumper to bumper with 8 to 10 feet to spare.
| Vehicles Or Use | Fit In A 24x30? | Notes |
|---|---|---|
| Two full-size pickups | Yes | About 3 ft of door room in each gap |
| Two cars or SUVs plus storage | Yes | Room for a mower, bikes or a workbench |
| Truck plus boat on a trailer | Usually | Check the boat's total length and height |
| Three cars | Tight | Three vehicles need about 26 to 30 ft of width |
| Tractor or farm equipment | Yes | Consider 10 ft or taller legs |
In our September 2026 price check, installed 24x30 metal carports were advertised starting at $3,555 with 7-foot legs, delivered and installed. A vertical-roof 24x30 with 6-foot legs was listed at $3,795 installed at another builder, certified for 150 mph winds and 35 psf snow.
What moves the price:
- Roof style: Regular roofs cost least and vertical roofs cost most. On a 30-foot-long carport, a vertical roof sheds snow, rain and leaves best.
- Leg height: Go to 9 or 10 feet for lifted trucks, trailers or farm equipment. Every foot adds steel.
- Sides and ends: Partial side panels, a closed back gable, or full walls add weather protection. Full enclosure turns the 24x30 into a two-car metal garage.
- Gauge and certification: 12-gauge framing and engineered drawings for your county's wind and snow loads cost more but are often required.
- Your state and site: Delivery zone, site access and grade all change the final quote.
Enclosing A 24x30 Carport
A 24x30 is also one of the most popular metal garage sizes, so many buyers start with an open carport and plan to enclose it later. Enclosed versions add walls, roll-up or walk-in doors, and sometimes windows. An enclosed building needs different bracing and certification than an open carport, so tell your builder up front if you might enclose it.
Concrete Slab And Anchors
Size the slab to the frame: a 24x30 frame under a 31-foot roof needs a 24' x 30' pad. Builders use concrete anchors on slabs, rebar or mobile home-style ground anchors on dirt or gravel, and asphalt anchors on paved surfaces.
Do You Need A Permit For A 24x30 Carport?
Almost certainly. At 720 square feet, a 24x30 is well above small-structure exemptions, and many areas also have setback and lot-coverage rules. Call your local building department before you order, and ask your builder for certified drawings.
Compare Other Carport Sizes
For two cars on a tighter budget, the 20x20 carport is the standard double size. For a single long truck, boat or camper, see the 12x30 carport. Browse all double car carports or every size in the carport sizes guide.
