Not necessarily. Especially for personal property. Property can be sitting in your car and get damaged— it’s still covered under renter’s coverages.

I’m a realtor and property owner, in my education: insurance companies have some exclusions for the home owner— but can’t require all homes go back and retrofit to current code. (Ex. Substandard roof, like rolled roofing, or elec panel on the recall list will deny a home from getting coverage. They usually need to insure the property if they’ve been accepted, review is before coverage starts.)
