Occupation Certificates

Q: Do you prepare Development Applications (DA) as a service?

No — PROCERT does not provide DA preparation services. PROCERT focuses on certification and approval services such as CDC, CC, Principal Certifier services and Occupation Certificates.

An Occupation Certificate (OC) confirms a building is suitable to be occupied or used in accordance with relevant approvals and requirements. Whether you need an Interim Occupation Certificate (allowing partial occupation) or a Final Occupation Certificate at completion, PROCERT can guide you through documentation, compliance checks and inspection requirements to support certification.

What is an Occupation Certificate (OC)?

An OC is issued when a building (or part of a building) is considered safe and suitable for occupation and use. It is typically required before a new building can be occupied, or before a change of use can commence.

🏠

Confirms suitability for occupation

The OC supports that the building is appropriate to be occupied or used in line with approvals and compliance requirements.

🧾

Requires supporting documentation

Depending on the project, you may need certificates, reports and evidence of compliance to support OC issuance.

✅

May be Interim or Final

An Interim OC can allow occupation of part of a building while works continue, while a Final OC is issued at full completion.

Tip: Plan ahead — OC requirements often depend on your approvals and project type. Early advice helps avoid delays at handover.

OC process and what you may need

OC requirements vary by project type and approvals, but most follow the same approach: confirm readiness, complete inspections, and provide the evidence required for certification.

Confirm readiness for inspection

We help identify what must be completed and what documentation is typically required before progressing to OC.

Complete inspections and compliance checks

Inspections may be required to confirm key items are complete and align with approved plans and requirements.

Provide documents and finalise certification

Once requirements are satisfied, we finalise the OC (Interim or Final) and outline any remaining conditions if applicable.
