Subsection 9.10.15. applies to the spatial separation between houses which may contain one dwelling unit above another.
The designer has the option of using either Subsection 9.10.14. or Subsection 9.10.15. for the determination of spatial separation requirements for these types of buildings. However, the requirements of these two Subsections cannot be mixed.
The buildings to which Subsection 9.10.15. applies include:
- traditional individual detached houses with or without a secondary suite,
- semi-detached houses (doubles) where each house may contain a secondary suite,
- row houses, where any house may contain a secondary suite (see Sentence 9.10.11.2.(1)), and
- stacked dwelling units where one of them is a secondary suite.
Subsection 9.10.15. does not apply to stacked row houses/townhouses or stacked dwelling units that are not within a house with a secondary suite.
