How to Install a Metal Carport + Safety Tips

If your current garage size lacks space for another vehicle, carports are a great investment. A carport can improve the overall property value of a home as well as provide weather protection for cars, boats, and other vehicles. 

While they’re great to have, building a carport from scratch can be a challenge for people with little to no construction experience. In this guide, we’ll show you how to install a carport and share a few helpful assembly tips.

Carport Installation Instructions

If you’re skilled in building or home projects, a do-it-yourself installation can be a smooth process. Let’s walk through a few key steps below. 

What You’ll Need

Before starting any work, it’s good to make a checklist of everything you need to successfully install your carport. Here are a few tools and materials you’ll most likely use:

Tools and EquipmentSafety Gear
• Ladder
• Hammer and nails
• Power drill and screws
• Shovel
• Pencil/Marker
• Tape measure
• Safety goggles
• Protective gloves



Step 1: Obtain a Building Permit (If Necessary) 

Before buying and installing a prefabricated metal carport, you’ll want to check with your local township or city clerk’s office to see if you need a building permit. 

Some jurisdictions have special regulations for permanent structures added to a residence. This may include the requirement of licensed builders or carport installers.

Step 2: Prepare the Site

After checking regulations and receiving the necessary permits, you can begin the site preparation. Choose a location on your property close to your house for easy access. Make sure the spot is away from large trees to avoid potential damage. 

The location should be properly leveled and in an area with excellent drainage. Doing so ensures the spot is ready for your foundation of choice

Once the ground is ready, the next step is to pour a concrete slab as the foundation for the carport. Make sure that it has been properly hardened before installing the carport. You can also use a gravel pad, asphalt, or your existing driveway as an alternative base.

Step 3: Follow the Assembly Instructions

Prefab carports come in kits where all pieces of the structure are pre-cut for precise fit. They should also include in-depth instructions for assembling your carport from the manufacturer. 
You will most likely need common household tools like power drills and screws to secure fastenings and anchor the carport to the foundation.

Do’s and Don’ts of Metal Carport Installation

To avoid hazards and ensure safe set up, here are a few assembly tips to keep in mind. 

  • Don’t install your carport on rainy or windy days. Strong winds and damp areas can result in slips and injuries, as well as affect the soil conditions. 
  • Do wear protective gloves, eyewear, and clothing during the installation process. Metal will heat up when exposed to direct sunlight, and certain parts have sharp edges.
  • Don’t forget about power lines, underground cables, and other power sources. Metal is a conductor of electricity and can be dangerous when it contacts an electric current. 
  • Do consider hiring a professional to help install your carport if you’re unsure or need assistance.

Frequently Asked Questions

How much does it cost to add a carport? 

Prefab carports can range anywhere from $1,200 to $5,000 depending on the size, style, and if you’re handling installation yourself. Some manufacturers may charge an additional installation fee.

How do you attach a carport to an existing house?

Unfortunately, prefab carports are designed as standalones and cannot be attached to homes or any other structure. You would have to custom build a carport from scratch to attach it. 

Do I need a foundation to install a carport?

Although carport foundations aren’t required, they are highly recommended. While you can use a dirt base to install a carport, it may not be as secure.
