Following completion of works, you can apply for an Occupation Certificate through the NSW Planning Portal, nominating your certifier.
You cannot legally occupy a building - or change the use of an existing building - until an Occupation Certificate is issued.
Occupation of a part of a building can be given by a ‘Part Occupation Certificate’, but there are limitations.
Refund of Bond
If you paid a bond or bank guarantee to cover damage to any Council assets or the environment as a result of the development work, you can request a refund after you receive your Occupation Certificate.
