We offer a wide range of sizes to accommodate your storage needs, from 5×5, or 25 square feet, to 10×30, or 300 square feet.* You can also contact one of our facility managers—they’re trained to help you out. *Sizes are approximate.

How do I use self storage?

Self storage can be used for many purposes: As an extension of your home and a place to store seldom-used items To store seasonal items such as decorations or sports equipment As a business storage solution to de-clutter your office or store inventory or equipment As a temporary home for your things while you move…and many more! First, make a list of what you want to store, and determine what size storage unit you need. Don’t forget to think about additional amenities like climate control , drive-up access, and convenient gate hours. Book your CubeSmart unit online at no cost or commitment, then go to the facility to complete your reservation. You’ll need to provide identification: a state-issued ID card, driver’s license, passport, or military ID. All that’s left to do is move in your stuff!
