Most people start in the same place. You look up the price of a one-car carport, see a number that feels reasonable, and think: “okay, that’s not bad.” Then the slab comes up. And that’s where the budget usually changes a bit.

Around Arkansas, a carport like this isn’t really just about the structure. It’s the whole setup. The steel frame, sure, but also the concrete, the anchors, the ground it’s going on, and whatever tweaks you need to make it actually fit your space.

By the time everything’s accounted for, a basic project tends to land somewhere between about $3,500 and $6,000. Some come in lower. Plenty go higher.

What Size Is a Standard One Car Carport?

A “standard” one-car carport usually measures around 12 feet wide, and 20 or 21 feet long. For a lot of vehicles, it’s enough. But it can feel tight. Especially after you’ve used it for a few weeks.

If you’ve got a truck, or even just like having room to open your door without thinking about it, going a little wider or longer starts to make sense. It’s not a huge jump in cost, but it changes how usable the space feels.

What Does the Carport Itself Cost?

The structure alone usually falls in the low-thousand-dollar range to start. But that number moves. Pretty quickly, actually, based on:

Roof style

A regular roof is usually the most economical option. A vertical roof costs more, but many Arkansas buyers prefer it because it helps with drainage and long-term performance.

Leg height

A standard height may work well for smaller vehicles. but if you own a truck or SUV, extra clearance can be worth the added cost.

Frame strength

Arkansas Metal Structures offers galvanized steel framing and steel panel systems, including common configurations with 14-gauge framing and 29-gauge panels.

Custom options

Custom upgrades can improve usability and appearance, but also raise the price.

How Much Does the Concrete Slab Cost?

For a 12x20 or 12x21 setup, you’re pouring somewhere around 240-ish square feet. Maybe a little more. Most of the time, concrete work ends up somewhere in the $4 to $8 per square foot range. So when you do the math, you’re looking at roughly $1,000 to $2,000 for the slab.

12x20 slab (240 sq. ft.): about $960 to $1,920
12x21 slab (252 sq. ft.): about $1,008 to $2,016

That’s the rough range, anyway. If the ground is already level and easy to work with, you might stay near the lower end. If it needs grading, or there’s drainage to deal with, or thicker edges, the price may start creeping up.

Why a Concrete Slab Makes Sense in Arkansas

You can install a carport without a slab. People do it. But in Arkansas, it doesn’t always hold up the way you’d hope. Between the rain, the mud, and how the ground shifts over time, having a solid surface underneath just makes life easier.

A concrete slab can offer:

A cleaner place to park
Better support and anchoring
Easier maintenance
Less mud around the structure
A more finished appearance
Better long-term value

For most homeowners, that ends up being worth the extra cost.

What Should Arkansas Homeowners Budget?

Once you combine everything, the numbers start to feel a little more grounded.

Economy Build

A simple setup might come together around $3,500 to $4,500.

Mid-Range Build

Step up the roof style, maybe go a bit bigger, put more into the slab, and you’re more in the $4,500 to $6,000 range.

Premium Build

After that, it really depends how far you want to take it. Taller builds, stronger framing, more site work… those can push things into the $6,000 to $8,000 range, sometimes more.

There’s no single price that fits every property.

What Pushes the Price Up?

A few things tend to move the number:

Site preparation

If your installation area is already level and accessible, your project will usually cost less. Arkansas Metal Structures notes that the install site should be level, or within about three inches of level, before installation.

Weather-related upgrades

Arkansas weather can be tough on outdoor structures, which is why many buyers choose stronger framing or better roof styles. Arkansas Metal Structures specifically markets its carports as engineered for Arkansas weather.

Custom sizing

If you need more clearance for a truck, a little more room for opening doors, or added storage space under cover, a custom size will increase the total.

Certification and local requirements

Some Arkansas locations may require certification, permits, or specific anchoring methods depending on the structure and jurisdiction.
