Dwelling coverage (Coverage A)

The part of a homeowners policy that pays to repair or rebuild the house itself, including attached structures such as a garage, porch or deck.

Also called: Coverage A, building coverage, dwelling limit

Dwelling coverage, labeled Coverage A on the declarations page, pays to repair or rebuild the house you live in and the structures attached to it, such as an attached garage, porch or deck. It reaches built-in items like cabinets, flooring, plumbing and wiring, and building materials stored on or next to the property for work on the home. The land is not covered.

On an HO-3, Coverage A is written on an open perils basis: it covers direct physical loss unless the policy excludes the cause, such as flood, earth movement or neglect. The limit also anchors the other coverages. The ISO form sets other structures at 10% of Coverage A, and insurers commonly start personal property at about 50% and loss of use at about 20%, so a $400,000 dwelling limit typically starts you near $40,000, $200,000 and $80,000.

The number to get right is the limit itself. It should reflect what it would cost to rebuild, not the market value or purchase price, because rebuilding costs follow labor and materials rather than the housing market. An underinsured dwelling can trigger a penalty at claim time, as explained under insurance to value. Our guide on how much dwelling coverage you need shows how to check your figure.
