Definition - What does Blanket Policy mean?
A blanket policy is a form of property insurance that covers more than one type of property at one location, or the same type at various locations, or multiple types at multiples locations. It allows the policyholder to extend the coverage of a basic homeowner's policy.
Insuranceopedia explains Blanket Policy
For example, blanket coverage may allow a homeowner to protect certain personal belongings or other items that their homeowner's policy does not. It may also provide coverage to specific kind of property, such as furniture, found within the home and in a storage unit elsewhere. Because a blanket policy offers additional coverage, a person cannot acquire it without a basic homeowner's policy.
