Which party is responsible for enforcing the Act after an order has been referred?

The principal authority that issued the permit holds the responsibility for enforcing the Act once an order has been referred. This is because the principal authority is typically tasked with ensuring compliance with building codes and regulations. When an order to comply is issued, it falls under their jurisdiction to monitor and enforce adherence to the directives laid out in the order, ensuring the safety and legality of constructions and modifications made to properties.

The role of the principal authority involves overseeing the implementation of orders regarding building permits and to address any issues that arise from non-compliance. They have the power to take necessary actions, such as issuing fines or further legal steps if the order is not followed, thereby reinforcing the regulations set forth by the Act.

In this context, while other parties like inspectors or property owners have roles in the process, enforcement of the Act after an order has been referred is primarily the responsibility of the principal authority. This situates them as the central figure in ensuring that the building standards and regulatory framework are upheld.
