Prefab garages are significantly less expensive than traditional garages. If you’ve ever compared the cost of a prefab garage with a traditional “stick-built” garage, you will quickly notice that the prebuilt option requires a significantly lower investment. Since prefab garage builders operate out of specialized warehouses with all the tools and materials at their easy disposal, they are able to build them much faster and with much less waste of materials. Building a traditional garage on the other hand, will require a lot of time and travel for work crews and transportation of materials. According to this in-depth article by homeadvisor.com average price per square foot on a traditional garage will be $50 per square foot. For simple price comparison, a 12×20 classic garage base price starts at around $32 per square foot from Northwood Outdoor. While the overall cost will depend on the options you choose, in either a prefab or traditional stick-built, you can expect around 25-40% savings if you go with the prefab option.
Here is a table using the above example. In this case, the prefab option saves a whopping $4320.

2. Ease of site preparation
Another reason that a portable garage will cost you less, is that getting the site ready is usually quite simple. Most prefab garages are set on simple stone bases similar to what is used for a traditional shed installation. A more traditional stick-built garage will almost always require a concrete foundation, contributing to a much higher build cost. In the case of a prefab garage, a motivated and industrious homeowner may even choose to do the entire site preparation themselves! Of course, before starting any shed project you will definitely want to check your municipality or township guidelines on any local ordinances or permits that may affect your garage project. The following video is a comprehensive look at site preparation considerations.
