A peril is a cause of loss. The TDI guide uses the term for events that can damage property and distinguishes named-peril and all-risk approaches.

The cause matters

Named-peril wording lists insured causes. Open-peril wording still includes exclusions, so “all risk” should not be read as “everything is covered.”

Different coverage sections can use different approaches. Read building and belongings terms separately and check endorsements.

See HO-3 versus HO-5 for form-review questions and what homeowners insurance covers for the wider reading checklist.
