What triggers the need for notification regarding the occupancy of buildings?

The need for notification regarding the occupancy of buildings is primarily triggered by the completion of construction work. This step is essential because it signifies that the building is now ready for use and has likely gone through the necessary inspections to ensure it meets safety and zoning regulations. Proper notification is required to inform the relevant authorities and stakeholders about the readiness for occupancy, which is crucial for compliance with local building codes and regulations.

While change in property ownership and change of use can affect how a building is utilized or categorized, they do not inherently trigger the same requirements for occupancy notification as the completion of construction. Upgrading utilities may improve the building's functionality but does not necessarily indicate that the building is complete or ready for occupancy in the context of safety and compliance. Therefore, the completion of construction stands out as the key event that necessitates notifying authorities about occupancy.
