HI HB643

Exempts sales and installation of wind resistive devices from Hawaii's general excise tax for the period January 1, 2016 through December 31, 2017.

Requires the Department of Commerce and Consumer Affairs to certify that wind resistive devices meet exemption requirements and to adopt rules under Chapter 91 to assess device qualifications.

Defines "wind resistive devices" as devices and techniques that increase building or structure resistance to wind damage, including uplift restraint ties, fastened roof sheathing, impact-resistant protective devices, wall-to-foundation connections, and residential safe rooms.

Takes effect July 1, 2050, with the exemption applying retroactively to gross proceeds received from January 1, 2016 through December 31, 2017.
