Intent 1:

To limit the probability of insufficient clear height over ramps serving a single dwelling unit or a house with a secondary suite including common spaces where occupants are likely to be intimately familiar with their surroundings.

This is to limit the probability of users accidentally contacting the ceiling with their head, which could lead to:

  • persons falling, or
  • persons falling in an emergency, which could lead to delays in the evacuation or movement of persons to a safe place.

This is to limit the probability of harm to persons.
