Standard homeowners insurance policies usually cover the other structures on your property. These include facilities that aren’t attached to your home, like guesthouses, gazebos, detached garages, sheds, mailboxes, fences and more.
Your policy protects these structures under dwelling coverage (specifically the Coverage B portion). Coverage B for other structures is typically set at 10% of your dwelling coverage limit. So if your dwelling limit is $200,000, your insurance coverage for other structures would be $20,000.
