TWIA & TDI
While Texas Windstorm Insurance Association (TWIA) is the insurance mechanism by which Texas coastal residents may secure windstorm and hail coverage, the Texas Department of Insurance (TDI) is the state agency charged with the enforcement of building codes and standards are met for the property being insured. Additions and alterations to existing property, as well as all new construction, must secure state certification of applicable building codes to be eligible for windstorm and hail coverage through TWIA.
