What does the cancellation of occupancy refer to in building regulations?

The cancellation of occupancy in building regulations refers to the termination of approved usage, indicating that a building or part of it is no longer permissible for the use that had been authorized. This can occur due to various reasons such as safety concerns, failure to comply with codes, or a change in the conditions under which the occupancy was approved. When occupancy is cancelled, it signifies that the building is not safe or suitable for the activities that were previously allowed, leading to potential legal and compliance issues for the owners and occupants. Understanding this concept is vital for ensuring safety standards and regulatory compliance within the built environment.
