Insurance – Self-storage facilities are generally not responsible for the contents of your unit so it is always a good idea to insure the goods you are storing. Self-storage insurance is almost always available to you at the time you rent your unit through the self-storage facility or through an independent third party who is referred by the self-storage property. Before you buy insurance, check with your own agent. In many cases, your homeowner’s or renter’s policy will cover you at no extra cost.
