If your home's unlivable from a covered incident, this'll help pay for temporary housing, food, and other living accommodations. That way, you can maintain your normal standard of living while away. In most states you'll be covered for up to 12 months. In others, coverage could last for 24. ALE coverage has a limit of 10% of your dwelling coverage. You can increase or decrease it to your liking. Just know that 10% might only cover a few months' living expenses.
