DA approved. Start building with your CC in hand.
"Our DA was approved but our original certifier couldn't issue the CC for three weeks. Every day of delay was costing us in holding costs and subcontractor rescheduling. No1 Building Services assessed our documentation in 48 hours and issued the CC in 8 business days, getting our project back on schedule."
A Construction Certificate (CC) is the mandatory approval confirming that your detailed construction drawings and specifications comply with the National Construction Code (NCC), Building Code of Australia (BCA), and the conditions of your Development Consent. No commercial construction work can legally commence without a valid CC.
- Required after DA approval, before any construction begins
- Confirms structural, fire safety, accessibility, and energy compliance
- Issued by your appointed Principal Certifier
- Lodged and managed via the NSW Planning Portal

Commercial CC FAQs
A CC is required before starting DA-approved commercial building work. If the work is approved by CDC, a separate CC is generally not required.
A Principal Certifier is appointed to carry out statutory certification functions, required inspections and OC assessment. Certification must be carried out by an appropriately registered certifier.
No. For DA-approved commercial building work, construction should not start until the CC is issued, the PC is appointed, required notices are given and pre-commencement conditions are satisfied.
We typically aim for 7-14 business days after receiving complete and compliant documents. Timing depends on project complexity, reports, referrals and further information.
