Notwithstanding the provisions of section 25.02.01 of this article, section 1705.13 of the Building Code is amended to read as follows:
1705.13 Special inspections for seismic resistance. Special inspections itemized in Sections 1705.13.1 through 1705.13.9, unless exempted by the exceptions of Section 1704.2, are required for the following:
1. The seismic force-resisting systems in structures assigned to Seismic Design Category C, D, E or F in accordance with Sections 1705.13.1.1 through 1705.13.1.2, as applicable.
2. Designated seismic systems in structures assigned to Seismic Design Category C, D, E or F in accordance with Section 1705.13.4.
3. Architectural, mechanical and electrical components in accordance with Sections 1705.13.5.
4. Storage racks in structures assigned to Seismic Design Category D, E or F in accordance with Section 1705.13.7.
5. Seismic isolation systems in accordance with Section 1705.13.8.
Exception: Special inspections itemized in Sections 1705.13.1 through 1705.13.9 are not required for structures designed and constructed in accordance with one of the following:
1. The structure consists of light-frame construction; the design spectral response acceleration at short periods, SDS, as determined in Section 1613.2.4, does not exceed 0.5; and the building height of the structure does not exceed 35 feet (10 668 mm).
2. The seismic force-resisting system of the structure consists of reinforced masonry or reinforced concrete; the design spectral response acceleration at short periods, SDS, as determined in Section 1613.2.4, does not exceed 0.5; and the building height of the structure does not exceed 25 feet (7620 mm).
3. The structure is a detached one- or two-family dwelling not exceeding two stories above grade plane, is not assigned to Seismic Design Category D, E or F and does not have any of the following horizontal or vertical irregularities in accordance with Section 12.3 of ASCE 7:
3.1 Torsional or extreme torsional irregularity.
3.2 Nonparallel systems irregularity.
3.3 Stiffness-soft story or stiffness-extreme soft story irregularity.
3.4 Discontinuity in lateral strength-weak story irregularity.
