Constructive total loss

A constructive total loss describes a house that still stands but is treated as lost, because repairs would cost more than the building is worth, or more than the policy will pay, or cannot lawfully be done. The phrase is common in auto and marine insurance, where a vehicle is "totaled" once repair cost passes a share of its value. Homeowners policies rarely set such a formula, so for a house the decision rests on the adjuster's estimate, the dwelling limit and local building rules.

Code rules are the usual trigger. Many communities require a building in a flood zone that is "substantially damaged" (repair cost at 50% or more of its pre-damage market value) to be brought up to current floodplain standards, often by elevating it. That can make repair impractical. In that situation ordinance or law coverage coverage on the homeowners policy and increased cost of compliance on a flood policy come into play. The substantial damage decision is made by the local building official or floodplain administrator, not by FEMA or your insurer.

If your insurer calls the house repairable and your engineer or contractor disagrees, get both opinions in writing and ask the insurer to explain its position in writing. The guide on when your house is a total loss covers what follows a total loss settlement.
