| Application | Application 1: Maximum spacing of wooden stringers for stairs serving
not more than one dwelling unit, where the risers
support the front portion of the treads, in buildings to
which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application
of Part 9]. Application 2: This also applies to stairs within dwelling
units, in buildings to which Part 3 applies
[see Sentence 1.3.3.2.(1) of Division A for application of Part 3], as
stated in Sentence 3.3.4.7.(1). |

| Intent | Intent 1: Where the continuous support of the treads and the lesser
loading due to the nature of the occupancy allow a greater span between stringers,
to limit the probability of excessive space between stringers, which could
lead to structural failure of the stringers, which could lead to harm to persons.
Intent 2: To supersede the requirement stated in Clause 9.8.9.4.(1)(d) regarding
the maximum distance between stringers, where the continuous support of the
treads and the lesser loading due to the nature of the occupancy allow a greater
span between stringers. |
