What is an Occupation Certificate?
An Occupation Certificate (OC) is the legal approval that authorises a building to be occupied or used. Under the Environmental Planning and Assessment Act 1979, occupying a new building – or changing the building use of an existing one – without a valid OC is an offence.
There are two types. An interim OC allows occupation of a completed portion of a building while work continues on the rest. A final OC is issued for the whole building once construction is fully complete. Both are legally referred to as partial OC and OC for the whole building, respectively.
Do You Need an Occupation Certificate?
An OC is required in the following situations:
You've completed construction of a new home, granny flat, townhouse, or apartment and want to move in
A multi-residential or commercial development is ready for handover or tenant occupation
You're completing a staged project and need to occupy part of the building while work continues elsewhere on site (interim OC)
You're changing the use or classification of an existing building, such as converting a commercial premises to residential
Your development consent or Complying Development Certificate (CDC) includes a condition requiring an OC before occupation

How It Works
Notify us that the build is complete: Once construction is finished (or a stage is complete for an interim OC), submit all required completion documents, including compliance certificates and contractor warranties.
Documentation review: We check all paperwork against the approved Construction Certificate (CC) or CDC plans, consent conditions, and critical-stage inspection records to confirm everything is in order.
Final site inspection: One of our certifiers inspects the completed building to verify it has been built in accordance with the approved plans and is suitable for occupation.
Outstanding conditions check: We confirm that any pre-occupation conditions have been met. This may include landscaping completion, driveway construction, stormwater connection, and payment of infrastructure contributions.
OC issued and lodged: Once we're satisfied, we issue the Occupation Certificate and lodge the required records with the consent authority and the NSW Building Commissioner's portal.
Timeframes
Most final Occupation Certificates are issued within days of the final inspection, provided documentation is complete and the building is compliant.
Delays typically arise when required documents are missing, such as fire safety certificates for commercial or multi-residential buildings, compliance certificates, or contractor warranties. Delays also happen when outstanding consent conditions haven't been met. Getting your paperwork together early is the best way to avoid a hold-up at handover.
