12x20 Garages

A 12 x 20 ft garage takes one car, SUV or pickup, or a boat or snowmobiles on their trailer, with room to walk around them. In this size you choose between two very different buildings. Portable garages from ShelterLogic stretch a waterproof polyethylene cover over a powder-coated steel frame: the Garage-in-a-Box, and the ShelterCoat in three roof styles — round, peak and barn, the barn in 9 ft or 11 ft heights — each in gray or green. The Sojag Everest is a permanent steel garage in Galvalume with an 8 x 7 ft roll-up door and a side door.

Headroom is the main difference: the ShelterCoat Barn 11 ft stands 10′10″ tall with a 103 in door opening, for a van, a pickup with a cap or a boat on its trailer, while the Garage-in-a-Box stands 8′6″. The ShelterCoat Round is rated for 90 mph winds and a 40 lb per sq ft snow load; the Everest for 100 mph and a 35 psf ground snow load. See also 12x24 garages, car shelters and 12x20 carports.

12x20 garage FAQ

What fits inside a 12 x 20 garage?

One vehicle with room to open its doors, or a trailer with a boat, an ATV or snowmobiles. Inside, the Garage-in-a-Box is 12′1″ wide by 19′11″ deep, the ShelterCoat Barn 11′8″ by 19′9″ and the Sojag Everest 11′9″ by 19′10″. Measure your vehicle's height, roof rack included, against the door opening on the product page.

Round, peak or barn roof?

A round roof sheds snow on its own and is the style ShelterLogic rates for wind and snow in this size. A peak roof gives a classic garage look. A barn roof keeps its full height further toward the walls, so it holds taller loads and shelving; the 11 ft barn has the tallest door of the range.

Portable or steel garage?

A portable garage costs less, goes up in a weekend and can come down in spring, but its cover is fabric and ShelterLogic's warranty is 1 year. The Sojag Everest is a permanent building: Galvalume steel walls and roof, a roll-up door you can motorise, and a 20-year limited warranty. It usually needs a permit and a proper base.

How do I anchor it, and what about snow?

ShelterLogic recommends one anchor per leg; the steel foot plates bolt to ground anchors, concrete or a pony wall, and the Garage-in-a-Box ships with temporary anchors only. Brush snow off a fabric roof after every storm. Snow-load ratings explained shows what a psf rating means where you live, and our portable garage assembly guide covers the set-up.
