In Plain Language

This article is marked 'Reserved' — the Code has held this numbering slot without an active requirement in it, a common practice that keeps clause numbering stable across editions even where content has been removed or relocated.

This is a plain-language summary of the 2012/2017 Ontario Building Code text above, for general understanding only and not a substitute for the Code. Always confirm current requirements against the 2024 edition (O.Reg. 163/24) or a qualified professional before construction.
