Commercial Building Certification Sydney
"Our retail lease started but the fitout could not open - the previous certifier had missed a BCA fire compliance requirement. No1 identified the gap, resolved it with the engineer, and we opened 11 days later."
Whether developing a new office building or performing a corporate tenancy fit-out, compliance with BCA Part D (access & egress), fire safety schedules, and mechanical ventilation is mandatory. We provide fast private certification so your project stays on schedule.
- Complying Development Certificates (CDC) for office tenancies issued in 5–20 days
- Construction Certificates (CC) and Occupation Certificates (OC) for new office developments
- Access, mobility, and fire safety audits handled by our unrestricted certifiers

Office Buildings & Fit-outs FAQs
Yes, if the fitout involves building work such as structural changes, altered egress, fire-safety changes, accessibility changes or services modifications. Some works may qualify for CDC instead.
Minor cosmetic works may not need certification. Work affecting walls, ceilings, fire systems, access, structure or services should be checked before starting.
An access report assesses whether the fitout meets applicable NCC accessibility requirements and relevant AS 1428 provisions.
