Storage needs for city dwellers may be different than the needs of a typical suburban family. In a city, you are often going to find mini storage facilities when you look for a self storage location.
These mini storage facilities are largely the same as other storage facilities, but they focus on the smaller storage units and have few larger storage spaces.
Storage rental in a city may be higher than it would be in a smaller town, but space is also at a premium. The typical resident of a large city, such as New York or San Francisco, will likely have fewer personal belongings (on average) than a typical suburban dweller.
The need for storage in a large city is often the result of changing apartments or needing to move apartments, but not being able to coordinate the move-in and move-out days perfectly. Additionally, city dwellers are often very limited in the space they have available to them in their apartments, and a storage unit comes in handy to give them extra space to store out of season clothing, sporting equipment, or recreational equipment that takes up too much space in their apartments.
Families with children may simply give away or discard clothing and furniture or equipment as the children move from infant to toddler and then to child, but some want to save these items for future children, nieces or nephews or for charity, and they will rent a mini storage unit for that purpose.
