How Do Home Insurance Companies Calculate Loss of Use?
They estimate what it costs to rent a comparable home plus extra living expenses, up to your policy's loss of use limit.

Loss of use usually appears on your quote as a set percentage of your dwelling coverage, calculated automatically rather than chosen by you. Your declarations page will list it as its own number, separate from dwelling coverage. If you're ever displaced, the insurer looks at what it would cost to rent a comparable home in your area, plus added costs like meals eaten out, and pays out until you're back in or that limit is reached. Before closing, check the figure against typical rental prices in your area.
Loss of use limits are not all the same
The percentage behind that number varies by insurer, and so does what counts as a comparable rental. Comparing quotes shows whether the limit on offer actually covers what your area would cost to rent.
What counts as a living expense under loss of use
Loss of use pays the added cost of living somewhere else, not your full rent or hotel bill. If a comparable rental costs more than your normal mortgage payment, the policy covers that difference. The same logic applies to other costs that come up because you're displaced. Extra miles driven to work from a temporary rental, laundry costs because the washer is in a house you can't access, pet boarding if the rental won't allow animals. Keep every receipt, since insurers ask for documentation before reimbursing any of it.
Meals work a little differently. If the kitchen is unusable, the insurer typically covers what you spend eating out above what you'd normally spend on groceries. It does not cover the full restaurant bill. Adjusters usually ask for a rough estimate of your normal food spending so they can calculate that difference. Knowing this going in helps. People sometimes expect every meal covered and find out otherwise partway through a claim.
Coverage starts when the home becomes uninhabitable because of a covered loss, something like a fire or a burst pipe. Routine renovation does not count. It ends when the home is repaired and ready to live in, or when you reach your policy limit, whichever happens first. If repairs run long because of contractor delays or materials on backorder, you're still only covered up to that limit no matter the reason for the delay. Some policies also cap the payout period at a set number of months even if the dollar limit hasn't been reached, so it's worth checking which kind of limit applies to your policy.
None of this applies if you're only temporarily inconvenienced, like a few days without power after a storm that left the home undamaged. Loss of use kicks in for displacement tied to a covered peril serious enough to make the home unlivable. Your declarations page shows the dollar limit, but the policy wording spells out what triggers that coverage and what it excludes. Reading that section before closing is worth the time, rather than learning it for the first time during a claim.
What triggers a loss of use payout and what doesn't
Loss of use only comes into play once an adjuster confirms the home is unlivable from a cause your policy actually covers. A pipe bursts and floods the living room, a kitchen fire leaves smoke damage through the whole upstairs, a tree comes through the roof during a storm. These trigger it. A dishwasher that stops working or a leaky faucet usually doesn't, because the home is still livable even if inconvenient.
Flood and earthquake damage are the two that catch new buyers off guard. A standard homeowners policy doesn't cover flood and usually excludes earthquake too. If either forces you out of the house, loss of use under a standard policy won't apply, because the underlying damage was never covered to begin with. If you're closing on a house in an area prone to either, this is worth checking into separately, since it affects more than just loss of use.
Chosen displacement doesn't count either. If you decide to repaint the whole house and can't sleep there for a week because of fumes, that's not a covered loss, so there's no loss of use payout. The same goes for a planned renovation that makes the kitchen unusable for a month. Loss of use responds to damage that happens to you, not plans you made yourself. Some policies draw a narrow line here, so if a claim involves any ambiguity about cause, the insurer will look closely at what actually happened before approving the expense.
Partial displacement gets handled case by case. If a fire damages only the upstairs bedrooms and the rest of the house is livable, an insurer might still cover a hotel if there's no safe way to isolate the damaged area, or might decide the home remains habitable and deny the claim. This is one of the more disputed areas of a loss of use claim, since habitability isn't always clear-cut. Asking how a policy defines uninhabitable, and whether that determination falls to the adjuster alone, is a fair question to raise before deciding between quotes.
Before you sign anything
Find the loss of use number on your declarations page and check it against what a comparable rental actually costs in your area. If the gap looks wide, that's worth raising while you're still comparing quotes.
