Tempo:
the roof provides lateral resistance by being either:
contiguous with the roof of the rest of the building with framing members not more than 400 mm (16 in.) on centre, or constructed with roof framing not more than 400 mm (16 in.) on centre fastened to the framing of the main structure.
Braced wall bands and braced wall panels on the front wall of an attached garage significantly change current construction, and the width would have to be increased to accommodate both garage doors and braced wall panels. Because people do not generally spend a lot of time in garages or accessory buildings and do not sleep in these buildings or spaces, less stringent requirements apply to these structures, provided they do not support more than one floor above the garage, have limited depth and have a certain percentage of the back and side walls constructed of braced wall panels.
The requirements for walls in detached garages and in accessory buildings serving a single dwelling unit are also less stringent, provided these walls are not supporting a floor.
BALLOON FRAMING For balloon-framed construction, both the studs and first-floor joists rest on the foundation sill plate (Figure 74) and an intermediate beam or bearing wall. Studs are toe-nailed to these supports with at least four 63 mm (2½ in.) nails; the joists in turn are nailed to the studs with at least two 76 mm (3 in.) nails. When lumber subfloor is laid diagonally, blocking is required between the joists at the wall lines to support the ends of the boards. Upper-floor joists bear on a ribbon board not less than 19 × 89 mm (1 × 4 in. nominal) that has been let into the studs, and the joists are nailed to the studs. The end joists parallel to the exterior walls on all floors are also nailed to the studs.
