Coverage E pays for the increase in normal living expenses the insured incurs while the described premises are unfit for normal use. This is an indirect loss of use coverage, so it applies only when a direct damage claim to A, B, or C is covered by the policy. These additional expenses include things such as rent for alternative housing and increased expenses for food, clothing, utilities, etc. The intent is to allow the family to maintain their normal standard of living, but it does not pay normal expenses that continue such as the mortgage.
