Guaranteed replacement cost

Dwelling coverage under which the insurer agrees to pay the full cost to rebuild, even above the policy limit, if the owner meets the policy's conditions.

Also called: guaranteed rebuild, guaranteed replacement cost coverage, guaranteed dwelling coverage

Guaranteed replacement cost promises to pay whatever it takes to rebuild your home with materials of like kind and quality, even if that is more than the Coverage A limit. That separates it from extended replacement cost, which stops at a stated percentage above the limit. In theory the guarantee has no ceiling.

The guarantee comes with conditions. Typically you must insure the home to 100% of the insurer's rebuild estimate, accept limit increases at renewal, tell the insurer promptly about additions and remodels, and rebuild at the same location. If you fall short, the insurer may reduce the guarantee to the policy limit or an extended amount. Many forms also set a lower limit for code upgrades or exclude special features.

Availability has narrowed. After years of surging construction costs and large catastrophe losses, many insurers stopped offering it, capped it or replaced it with extended replacement cost. If your policy still has it, the most useful step is keeping the records the conditions depend on. Report each renovation in writing, keep the insurer's rebuild estimate in your file, and test your limit with How much dwelling coverage do I need?. See extended and guaranteed replacement cost coverage for the difference in practice, and insurance to value for the ratio insurers watch.
