§ 5C-2-1 H AWAI‘I C OUNTY C ODE <br />(8) Subsection 506.4.2, “Snow and wind loads,” of the International Existing <br />Building Code is amended to read as follows: <br />“506.4.2 Snow and wind loads. Where a change of occupancy results <br />in a structure being assigned to a higher risk category, or where the <br />change is from a Group S or Group U occupancy to any occupancy <br />other than Group S or Group U, the structure shall satisfy the <br />requirements of Sections 1608 and 1609 of the Building Code, Chapter <br />5A, for the new risk category. <br />Exceptions: <br />1. Where the area of the new occupancy is less than 10 percent <br />of the building area, compliance with this section is not <br />required. The cumulative effect of occupancy changes over <br />time shall be considered. <br />2. Where the change is from a Group S or Group U occupancy, <br />use of 75% of snow and wind forces shall be permitted.” <br />(9) Subsection 506.4.3, “Seismic loads,” of the International Existing Building <br />Code is amended to read as follows: <br />“506.4.3 Seismic loads (seismic force-resisting system). Where a <br />change of occupancy results in a building being assigned to a higher <br />risk category, or where the change is from a Group S or Group U <br />occupancy to any occupancy other than Group S or Group U, the <br />building shall satisfy the requirements of Section 1613 of the Building <br />Code, Chapter 5A, for the new risk category using full seismic forces. <br />Exceptions: <br />1. Where the area of the new occupancy is less than 10 percent <br />of the building area, and the new occupancy is not assigned to <br />Risk Category IV, compliance with this section is not <br />required. The cumulative effect of occupancy changes over <br />time shall be considered. <br />2. Where a change of use results in a building being reclassified <br />from Risk Category I or II to Risk Category III and the <br />seismic coefficient, S, is less than 0.33, compliance with this <br />DS <br />section is not required. <br />3. Unreinforced masonry bearing wall buildings assigned to <br />Risk Category III and to Seismic Design Category A or B, <br />shall be permitted to use Appendix Chapter A1 of this code. <br />4. Where the change is from a Group S or Group U occupancy, <br />use of reduced seismic forces shall be permitted.” <br /> <br />SUPP. 11 (1-2022) <br /> <br />5C-8 <br /> <br />
