Section 2308.1 General. The requirements of this section are intended for conventional light-frame construction. Other methods are permitted to be used, provided a satisfactory design is submitted showing compliance with other provisions of this code. Interior non- load -bearing partitions, ceilings and curtain walls of conventional light-frame construction are not subject to the limitations of this section. Section 2308.3.4 of the California Building Code, 2013 Edition is amended as follows: Section 2308.3.4 Braced wall line support. Braced wall lines shall be supported by continuous foundations. Exceptions: 1. One-story buildings with maximum plan dimension not exceeding 50 feet (15240 mm), may have continuous foundations located at exterior braced wall lines only. 2. Two-story buildings with a maximum plan dimension not exceeding 50 feet (15240 mm) may have braced wall lines supported on continuous foundations at the exterior walls only, provided: a. Cripple walls do not exceed 4 feet (1219 mm) in height. b. Where the first story is supported on a raised wood framed floor, the interior braced wall panels are directly supported by doubled joists, continuous 4x blocking or minimum 4x floor beams. Section 2308.12.4 of the California Building Code, 2013 Edition is amended as follows: 2308.12.4 Braced wall line sheathing. Braced wall lines shall be braced by sheathing prescribed by Table 2308.12.4 as shown in Figure 2308.9.3. The sum of lengths of braced wall panels at each braced wall line shall conform to Table 2308.12.4. Braced wall panels shall be distributed along the length of the braced wall line and start at not more than 8 feet (2438 mm) from each end of the braced wall line. Sheathing shall be minimum of 3/8” thick and be fastened to studs, top and bottom plates and at panel edges occurring over blocking. Wall framing to which sheathing used for bracing is applied shall be nominal 2 inch wide [actual 1½ inch (38 mm)] or larger members, spaced a maximum of 16 inches on center. Nailing shall be minimum 8d common placed 3/8 inches from panel edges and spaced not more than 6 inches on center, and 12 inches on center along intermediate framing members. Cripple walls having a stud height exceeding 14 inches (356 mm) shall be considered a story for the purpose of this section and shall be braced as required for braced wall lines in accordance with Table 2308.12.4. Where interior braced wall lines occur without a continuous foundation below, the length of parallel exterior cripple wall bracing shall be one and one-half times the lengths required by Table 2308.12.4. Where the cripple wall sheathing type used is Type S-W and this additional length of bracing cannot be provided, the capacity of Type S-W sheathing shall be increased by reducing the spacing of fasteners along the perimeter of each piece of
