Frequently Asked Questions

  • How do I know what storage unit size I need? Start by listing the items you plan to store. Then compare your items to common unit sizes, such as a closet, walk-in closet, one-car garage, or two-car garage.
  • Should I rent a larger storage unit than I think I need? If you want easier access, plan to add more items later, or need room for an aisle, choosing a slightly larger unit may be helpful.
