Car storage units in SeaTac, WA, and nearby areas

Q: What size storage unit is best for a car?

A 10’&#215;20’ unit is the go-to size for most standard cars. Compact cars? You might only need a 10’&#215;15’. Trucks, vans, or larger SUVs? A 10’&#215;30’ will give you the extra space you need.

Q: Can two cars fit in a 10&#215;30 storage unit?

Yes – in most cases! A 10’&#215;30’ unit is about the size of a standard two-car garage, so you can usually fit two compact vehicles side by side.

It's as clean as one can expect a storage place to be. Employees were cheerful, welcoming, watchful without being nosey. It's secure. My son has had the same unit for many years now without problems! Thank you!

24 hour access says it all, especially when you're using it as a place to store ur businesses merchandise. The only issue I have is it's not climate controlled but some insulation foam should help with that.

I have been dealing with the Burien location for a couple years now. The office managers have always awesome and very helpful! They have gone over and above helping us, a few times when we had some urgent business that required a little extra from them. Sammy, Ashley... everybody that works there is always cheerful and quick with a smile and ready to be helpful if needed and even if it isn't needed. The grounds are well kept and clean. Adam really seems to take pride in keeping things well maintained. Would highly recommend!

Mrs. Shirley was incredibly helpful throughout the entire process of selling me a storage unit to keep all my belongings safe and organized. From the moment I walked in, she was friendly, patient, and genuinely attentive to my needs. She took the time to explain the different unit sizes, pricing options, and security features, making sure I felt confident in my choice. Her professionalism and willingness to answer all my questions made what could have been a stressful experience feel easy and straightforward. Thanks to Mrs. Shirley, I was able to find the perfect storage solution without any hassle.
