R ESIDENTIAL B UILDING C ODE §5B-2-1 <br />(8) Table R301.2(1), “Climatic and Geographic Design Criteria,” of the <br />International Residential Code is deleted in its entirety and replaced with the <br />following: <br />“TABLE R301.2(1) <br />CLIMATIC AND GEOGRAPHIC DESIGN CRITERIA <br /> <br />WIND SEISMIC <br />SUBJECT TO DAMAGE FROM <br />FLOOD <br />SPEED DESIGN <br />HAZARDS <br />Weathering Termite Decay <br />(mph) CATEGORY <br />Per FEMA or <br />Very Moderate <br /> <br />Figure D2 or E NegligibleChapter 27 <br />Heavyto severe <br />R301.2(8) HCC” <br />(9) Subsection 301.2.1, “Wind design criteria,” of the International Residential <br />Code is amended to read as follows: <br />“R301.2.1 Wind design criteria. Buildings and portions thereof <br />shall be constructed in accordance with the wind provisions of this <br />, as <br />code provided that the ultimate design wind speed, V <br />ULT <br />determined from Figure R301.2(5)A, is less than 130 mph, unless the <br />building is a single-story with a slab-on-grade foundation and in wind <br />exposure category B, then wind provisions of this code shall be <br />applicable when V is less than 140 mph. The structural provisions <br />ULT <br />of this code for wind loads are not permitted where wind design is <br />, determined from Figure R301.2(5)(A), is equal to <br />required when V <br />ULT <br />or greater than 130 mph, unless the building is a single-story with a <br />slab-on-grade foundation and in wind exposure category B, then <br />structural provisions of this code for wind loads are not permitted <br />where wind design is required when V is equal to or greater than <br />ULT <br />140 mph. Where different construction methods and structural <br />materials are used for various portions of a building, the applicable <br />requirements of this section for each portion shall apply. Where not <br />otherwise specified, the wind loads listed in Table R301.2(2) adjusted <br />for height and exposure using Table R301.2(3) shall be used to <br />determine design load performance requirements for wall coverings, <br />curtain walls, roof coverings, exterior windows, skylights, garage <br />doors and exterior doors. Asphalt shingles shall be designed for wind <br />speeds in accordance with Section R905.2.4. A continuous load path <br />shall be provided to transmit the applicable uplift forces in Section <br />R802.11.1 from the roof assembly to the foundation. The ultimate <br />design wind speed, V, in the State Residential Code is equal to the <br />ULT <br />basic design wind speed, V, in the Building Code, Chapter 5A, Hawai‘i <br />County Code. <br />SUPP. 16 (7-2024) <br />5B-9 <br /> <br />
