9.23.10.1. — Stud Size and Spacing
(1) Except as provided in Sentence (2), the size and spacing of studs shall conform to Table 9.23.10.1.
(2) Studs for walls not listed in Table 9.23.10.1. and supporting roof loads shall conform to Table A-30 to A-33, provided,
(a) the studs are clad with not less than 9.5 mm thick plywood, OSB or waferboard sheathing on the exterior face, and not less than 12.5 mm gypsum board on the interior face,
(b) solid bridging is provided at not more than 1 200 mm on centre,
(c) the studs are fastened to the top and bottom plates with no fewer than three 82 mm toe-nails,
(d) the double top plates are fastened together with not less than 76 mm nails spaced not more than 200 mm on centre,
(e) roof framing members spaced not more than 600 mm are fastened to the top plates with no fewer than four 82 mm toe-nails, and
(f) the bottom plate is fastened to the floor joists, blocking or rim joist with not less than 82 mm nails spaced not more than 200 mm on centre.
Editor's note
In the appendix tables for Article 9.23.10.1. (Table A-30 through Table A-33, Maximum Spans for Roof Joists and Rafters), the note markers '(1)' to '(4)' are superscripts each followed by a space and the headnotes are in plain weight, as filed in O. Reg. 350/06; the e-Laws consolidation removes the space after each marker, sets the headnotes in bold, and renders the markers of Tables A-30 to A-32 as plain text (those of Table A-33 remain superscript). The Table A-30 column heading also reads 'DesignSnow' run together as filed (a missing space), which this map reproduces; the e-Laws consolidation supplies the space ('Design Snow'). The table content is otherwise identical and none of these changes was enacted by an amending regulation.
