Under which coverage in a dwelling policy would a detached garage be insured?

The detached garage is insured under Coverage B - Other Structures in a dwelling policy. This coverage is specifically designed to insure structures on the property that are not attached to the primary dwelling. Coverage B typically includes garages, sheds, fences, and other similar structures that are separate from the home itself.

Coverage A pertains to the main dwelling and any attached structures, while Coverage C focuses on personal property owned by the insured. Coverage D is meant for lost rental income due to a covered loss affecting rental properties. Therefore, detaching the garage from the main dwelling means it would fall under the category of "other structures," ensuring that it is covered against risks specified in the policy.
