Post-Consent Certificates

Occupation Certificate

The Occupation Certificate (OC) authorises the occupation and use of a new building or part of a building.

The Occupation Certificate (OC) authorises the occupation and use of a new building or part of a building. For staged works, a Part OC may be issued which allows you to occupy the completed part of the building.

Depending on the particular OC sought, the Principal Certifier must be satisfied the development meets various regulatory standards. These generally include that:

  • A development consent is in force.
  • The design and construction of the building is not inconsistent with the development consent.
  • Any pre-conditions set out in the consent or requirements of planning agreements have been satisfied.
  • A Construction Certificate (CC) has been issued.
  • That the building is suitable for occupation (in accordance with its Building Code of Australia (BCA) classification).

Issuing the OC for the whole of the development is the last step in the formal Development Application (DA) and construction process (though there could be ongoing ‘operational’ conditions such as maintaining appropriate noise levels or landscape maintenance).

Class 2 Residential applications

Property developers for Class 2 developments are required to lodge their intention to seek an Occupation Certificate.

As such, compliance gates to ensure compliance with the Residential Apartment Buildings Act, Strata Schemes Management Act 2015 and the Design and Building Practitioner Act 2020 have been implemented into the NSW Planning Portal to prevent the applicant/property developer from initiating an application for an occupation certificate if compliance gates are not met.

These are:

  • Failure to give notice within 6-12 months before the application for the occupation certificate was made.
  • Failure to give expected completion amendment notice (if original estimate expected date changed).
  • Failure to give your intention to commence building work, for building work starting after 1 July 2021.
  • Fair Trading compliance officers have determined that a pre-OC audit is required, or serious defects exist.
  • Compliance declarations and regulated designs not lodged by registered practitioners.
  • Strata building bond under Strata Management Act 2015 has not been lodged with associated documents, if applicable.

Compliance declarations are lodged online through NSW Planning Portal. Certain declarations must be lodged: before building work commences, as variations arise, before the issue of an OC, and 90 days after OC is issued.

More information on the application process for developers and practitioners, including the intent to seek an occupation certificate, is available in our Developer and Practitioner Resources section.
