Questão jurídica principal
Whether a full-site floor-area compliance proof could be required for a partial conversion despite a prior validly ordered AZ transfer for the existing building mass.
Decisão extraída
No. For a project affecting only part of the building, the authority may require proof only for the additional floor area, not a new conformity test for the entire property.
Fundamentação extraída
Requiring full-site proof would in substance partly revoke the earlier final building permit that had expressly ordered the AZ transfer and registered it in the land register. Where the existing overuse remains unchanged and only additional area is legally covered by a new transfer, the difference between an AZ-neutral conversion and an AZ-increasing conversion cannot justify disparate treatment.
