Which type of endorsement would amend the definition of resident premises in a homeowners policy?

The endorsement that would amend the definition of resident premises in a homeowners policy is related to mobilehomes. This is because mobilehome endorsements specifically expand the coverage to include mobilehomes as part of the residence. They define what constitutes a resident premises by including mobile homes within the scope of coverage, which is important in states where mobilehome living is common. This ensures that homeowners living in mobilehomes have the necessary coverage for their specific type of dwelling.

In contrast, the other options – business pursuits, personal injury, and watercraft – serve different purposes. The business pursuits endorsement addresses liability related to business activities conducted in the home, the personal injury endorsement pertains to coverage for claims of personal injury, and the watercraft endorsement relates specifically to boats and watercraft. None of these endorsements change the definition of what constitutes a resident premises in the same way that a mobilehome endorsement does.
