What kind of coverage does a structural warranty from 2-10 HBW include?

A structural warranty for home builders provides 1 year surety coverage for workmanship, 2 years surety coverage for distribution systems and a full 10 years of third-party insurance-backed coverage for qualifying structural defects on newly constructed homes. Builders must register to become members of the 2-10 HBW program, and home buyers may refer their builder.
