Tips for Choosing a Portable Garage Size

Matching your garage’s width with your family’s unique needs is critical for ensuring easy access and functionality. Choose a 10’ wide garage if you need room for a dedicated workshop or storage area, motorcycles, or compact cars, and don’t have much space for a larger building.

Go with a 12’ wide or larger garage for small trucks, SUVs, or sedans. The extra room allows for effortless maneuvering and door clearance, as well as additional workspace or storage along the building’s sides. An 18×20 garage is also available for a full-size pickup truck, van, or SUV, a small boat, or a trailer.

FAQ

Why choose portable garages over permanent ones?

Portable structures are ideal for people requiring temporary storage, renters, and seasonal use. Unlike a permanent garage, a portable structure generally doesn’t require a building permit or foundation, making it easy to remove or relocate as needed.

How long will my portable garage last?

Wood-framed garages with metal roofing and treated lumber may last 15 to 25 years, or longer. The metal siding and wood framing combine the weather resistance of metal exteriors with the durability of treated lumber for a long-lasting storage solution.

What do I need to maintain a portable garage?

Repainting or resealing your garage’s exposed interior wood and trim every 2 to 5 years can help protect against UV and moisture damage. Wash the roof and siding every year to remove corrosive buildup, pollen, and dirt, lengthening your garage’s life. Ensure ample airflow to keep mildew or mold at bay, particularly if you plan to store objects that retain moisture (e.g., lawn equipment, firewood).

Can a portable structure hold up against high winds?

Yes, whether you choose a 10’ wide garage or an 18×20 garage, you can expect a quality garage to feature the exceptional structural integrity required to withstand heavy winds or snow. Look for wood-framed garages with metal roofs and reinforced floors, as these fare better than their fabric counterparts. A tie-down kit, ground anchors, and concrete piers can further aid in resisting uplift.
