Room area requirements for dwelling units, dormitories, boarding houses, and rooming houses are governed by Part 9 rather than by this Section, keeping the detailed room-sizing rules in one consistent place in the Code.

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.
