You need for coverage depends on the homeowner’s renter’s insurance you already have. But the short answer is, YES! You do need to make sure your belongins are insured.
The good news is that most standard homeowner’s and renter’s insurance policies cover personal property, even if it isn’t in your home. That should include the items in your storage unit.
However, the property coverage for items inside and outside of your home is not necessarily equal. Depending on your policy, your stored items could have a little as 10 percent of the coverage of the belongings in your house. That’s as a huge discrepancy. So if you’re putting in storage, one of your first steps should be to ask your insurance agent how much coverage your policy provides for stored items.
