What does Part 10 govern?

Part 10 of the Ontario Building Code specifically addresses the requirements and guidelines related to changes in major occupancy, particularly when no construction is proposed. This section provides direction on how to manage situations where the occupancy classification of a building changes, potentially impacting health and safety standards, fire protection measures, and other aspects of building safety.

Understanding this part is crucial for ensuring that any major changes to how a building is used are handled appropriately, maintaining compliance with necessary regulations without the need for construction work. It emphasizes the importance of evaluating the implications of a change in use in the context of the built environment and ensures that existing structures remain safe and functional in their new role.

Other options focus on aspects that are governed by different parts of the Ontario Building Code, such as maintenance requirements, energy consumption standards, and demolition procedures, but they do not pertain to occupancy changes without proposed construction.
