9.10.8.10.(1)

Intent 1:

To limit the application of Article 9.10.8.1. by excluding certain dwelling units and houses with a secondary suite.

Intent 2:

To exempt certain dwelling units and houses with secondary suites from the requirements of Sentence 9.10.8.1.(1), which would otherwise require a minimum fire-resistance rating for floor and roof assemblies, on the basis that:

• the vertical spread of fire from one unit or occupancy to another is not possible, and
• for houses containing a secondary suite:
  • the construction of rated fire separations may be cost-prohibitive, and
  • the reduction in protection from spread of fire is off-set by more stringent requirements for notification of occupants.
