The type of self storage space that is very similar to the drive up unit is the indoor unit. These units are completely enclosed, but their doors do not open to the outside. Instead, they are completely inside of the building and the unit doors are along hallways. Sometimes these buildings can have more than one floor of storage units. Often this type of storage unit is used for more valuable items or those that need to be in a controlled environment for protection. This means that the temperature and the humidity level are regulated using air conditioning, heat, and a dehumidifier. Not every unit of this type offers humidification, so it is best to ask before renting.
The final type of self storage space is the outdoor one. This is basically a parking space on a gravel or paved area within the fenced in facility grounds. Sometimes they may have some type of roofing over the space or be somewhat enclosed with cinder block walls for a bit of additional protection from the elements. This type of storage space can be rented for nearly any type of vehicle, including boats with trailers, as long as it is in working condition and has current permits.
Usually a self storage facility will have several different sizes of the storage space types that they offer, which can range from the size of a closet to a space for a full size RV. This helps the customers find the perfect fit for the items that they want to store there.
