What Is a Prefab Garage

So what is a prefab garage? A prefab or modular garage is a garage that has been built off-site at a manufacturing facility and is then delivered to your location as a unit or in a few sections for an easy set or installation on-site.

A prefab garage gives you the flexibility of a portable building and all the benefits of a garage. And while the term “prefab”, which is short for “prefabricated”, has a bad reputation in the construction industry, today’s prefab buildings are not a compromise in quality or value. Rather, they are an affordable and practical alternative to the expensive and time-consuming process of building an on-site garage.

So what is a prefab garage? In today's world of fast food, on-demand streaming services, and same-day delivery, a prefab garage is a great alternative to an on-site constructed garage, both in time and cash.

NOTE: In areas where building code is enforced, these prefab garage sheds don't meet the regulation for vehicle storage, but are rather ideal to be used as a storage building with large doors for easy access to your lawn equipment, ATV, or golfcart, etc.

Are Prefab Garages Worth it?

A well-built, prefab garage is a great investment to add to your property. And while a prefabricated garage might sound like a lesser-value building, when you purchase from a reliable prefab shed and garage builder, this is simply not the case. One of the misnomers that are usually cited in a conversation about prefab garages is the fact that they are built using lower-quality materials.

While that may be true in some cases, when you go with a local, reliable, prefab garage builder, like Colorado Shed Company, you will not only get top-quality material, and top-notch workmanship, but also great customer service with a personalized touch.

What is the difference between Prefab, Modular, and Portable Garages?

As you have been looking into what kind of garage you want to build, and what is a prefab garage, I’m sure you’ve come across different terms, like prefab, modular, and portable. The terms prefab and modular are pretty much synonymous. And while each has its own definition, ultimately, they all mean pretty much the same thing. Which is a building that has been built in a manufacturing facility and then is moved to your location after its complete or built-in sections and then delivered and assembled on-site, instead of being built from the ground up at your location.


Prefab is short for “prefabricated,” which means “made beforehand,” and not “before fabulous.” Prefab things are made in sections that can be easily shipped and put together to form a finished product.


Use the adjective modular to describe something that is made up of pieces or parts, like a new house that is delivered in sections and then assembled.


If something's portable, you can easily take it with you. You may carry your portable computer with you from class to class because it's small, light, and fits easily in your backpack.

Pros and Cons of Prefab Garages

Pros of a Prefab Garage


While not necessarily known as a high-quality solution to your garage needs. When done right, and built with attention to detail and quality, a prefab garage finds that balance of affordability and quality.

Save Time & Money:

Investing in a prefab garage not only saves you the extra money and hassle required if you go with the traditional on-site construction route. A prefab garage only requires a stone or concrete pad, instead of a full foundation. This also allows you to get your garage installed quickly, without having to wait on construction time, weather, and all the other factors that go into a construction project.


Of course, when we say "portable garage," we’re not talking about picking it up and moving it on a whim, but we are talking about the ability to relocate your garage in the event that you would move, or just need your garage in a new location. This is one of the advantages of detached garages vs. attached garages.

Cons of a Prefab Garage

Limited by Size:

If you are looking for a larger, multi-car garage, then a prefab garage might not be the best route for you, due to the nature of a prefab building. Don’t forget to check with your local prefab garage builder to find out what size garages they offer before dismissing the idea of a prefab garage for yourself and to help you answer the question of what is a prefab garage.

Fewer Customizations Available:

While it is true that a prefabricated building will generally not have as many customizations as an onsite garage would, especially with unique designs and layouts, most prefab garage builders will have plenty of add-ons and customizations available. So whether it's a couple of extra windows, a loft, or getting your garage insulated, personalizing your garage is still possible.
