Summary: The progressive expansion of the occupancy certificate exemption, extending the threshold from 1,200 square feet to 2,400 square feet and from ground+2 floors to ground+3 floors, shows a clear legislative intent to broaden administrative relief to owners of small residential properties. However, the lifting of the occupancy certificate requirement neither diminishes the obligation to comply with approved building plans and safety standards, nor can it be construed as authorisation for deviation from substantive compliance requirements under applicable building laws and town planning legislation.
