Security Often self storage units offer more security than homes. Self storage facilities provide security features not normally found on homes. In addition to a lock, facilities are often protected by a security fence, surveillance cameras, a gated entry, limited entry after hours, exterior lighting and possibly security guards or onsite management. You may choose to purchase an in-home security system for your home. While this may protect the items stored in your home, will it protect items left in your yard? What about that backyard storage shed? Self storage units give you the benefits of both extra storage space and added security.
