This page outlines building and certification-related processes and requirements, including fire safety, pools and spas.

If you're planning on building and your development application is approved (consent issued), you must:

have a construction certificate
appoint a principal certifier (PC) to carry out inspections during the construction process.

Appoint a principal certifier

You will need to appoint a PC before starting any building work. A PC is a registered certifier that oversees the construction or subdivision process. The PC carries out the required inspections throughout the construction period at critical stages. The PC's role is to ensure the development is completed in line with the:

conditions of the development consent, approved plans and documents
National Construction Code
associated restrictions listed on the title of the property.

Once construction is complete

Once building work has finished, your PC will carry out final inspections and may issue the occupation certificate if you've met all requirements.
