3.1.3.1. — Separation of Major Occupancies

(1) Except as permitted by Sentences (2) and (3), major occupancies shall be separated from adjoining major occupancies by fire separations having fire-resistance ratings conforming to Table 3.1.3.1.

(2) In a building not more than 3 storeys in building height, if not more than 2 dwelling units are contained together with a Group E major occupancy, the fire-resistance rating of the fire separation between the 2 major occupancies need not be more than 1 h.

(3) The fire separations required between major occupancies in Sentence (1) are permitted to be penetrated by floor openings protected in conformance with Subsection 3.2.8., except for fire separations for Group F, Division 1 major occupancies and for mezzanines described in Sentence 3.2.8.2.(1)v1v2.

Editor's note

In the notes to Table-3.1.3.1., a separating space follows the footnote reference numbers; the e-Laws consolidation omits it. The footnote text is identical.
