18 x 20 ft Car Shelters & Winter Car Shelters

A winter car shelter keeps snow, ice and freezing rain off your car, truck or SUV for a fraction of the cost of a garage. IPATIO carries the shelters Canadians actually buy: ShelterLogic AutoShelter and Garage-in-a-Box for one vehicle, ShelterCoat round, peak and barn units from 10x16 to 22x28 ft, ShelterTube garages up to 20x32 ft, and Gazebo Penguin single and double car shelters. Every frame is galvanized steel; the covers are UV-treated polyethylene made to shed snow.

Choose by size

10 x 20 ft — one car or a small SUV (AutoShelter, Garage-in-a-Box)
12 x 20 ft — pickups and SUVs, with room to open the doors
13 x 20 ft and 12 x 24 ft — full-size trucks, or a car plus a snowblower
12 x 28 and 13 x 28 ft — two vehicles in line, or a boat on its trailer
18 x 20 ft and wider — two vehicles side by side

Need a permanent steel structure instead? See our carports and portable garages, and read the winter car shelter guide before you choose.

Car shelter FAQ

Do I need a permit for a temporary car shelter?

Most Canadian municipalities allow a temporary car shelter without a permit during winter only — typically from mid-October to mid-April — with rules on setbacks and the distance from the street. Dates and setbacks vary from one municipality to the next, so check your local bylaw before you install.

Will it hold up to Canadian snow?

ShelterLogic's wind-and-snow-rated ShelterCoat and ShelterTube frames are engineered for winter loads; AutoShelter and Garage-in-a-Box are lighter single-car units. Whatever the model, brush heavy snow off the cover after a storm and keep the frame tensioned and anchored.

How is a car shelter anchored?

ShelterLogic shelters include auger anchors for soil and gravel. On asphalt or concrete, use a permanent anchor kit or weighted anchors so the frame cannot lift in a winter wind.

How long does setup take?

Two people can assemble a single-car shelter in an afternoon with basic tools; the largest ShelterCoat units take a day. Every shelter ships flat, with free shipping on most orders over $88*.

*Conditions apply. See our Shipping Policy for details.
