Since its first location opened in Salt Lake in 2001, Hawaii Self Storage has grown to five locations on Oahu. Spaces range in size, so you can store small household items, bigger furniture and kayaks, and even your vehicle. An intriguing trend: Some small- business owners rent a storage unit to use as an office space. Owner Mike Wood is a philanthropist. His company’s “Transition Assistance Program” offers free or reduced- rate storage to help families who have been laid off from jobs or had their homes foreclosed on.
