Ontario Building Code, O.Reg 332/12 · Table 1.3.1.4.

Overview

A one-page City of Mississauga information sheet reprinting Ontario Building Code article 1.3.1.4 in full. It lists the changes of use the Code treats as an increase in hazard under section 10 of the Act: a change of major occupancy designated with a Y in Table 1.3.1.4., a Group C suite converted into more than one Group C suite, conversion to gaming premises, a farm building changed to a major occupancy, a change to a post-disaster building or a retirement home, and an undeterminable previous occupancy. Two exemptions follow.
