Whether your homeowners insurance is cancelled or not renewed, the result is the same: your insurance policy is being discontinued. But the rules for each are a bit different. Nonrenewal occurs at the end of the term when the policy is expiring and may occur for multiple reasons. An insurance company generally may cancel your policy within a certain number of days after the inception of your policy for any reason. After that, they're typically only able to cancel the policy for limited reasons, such as the following:
Nonpayment
Material misrepresentation or fraud occurs
A substantial change in risk happens
