Frequently Asked Questions
Our FAQs cover the most common queries about CDCs, CCs, inspections, and more. Whether you’re a homeowner or a builder, we aim to provide clarity and confidence throughout the process. If you need more help, our team is just a call or click away.
What documents are needed for my application?
To begin the certification process, you’ll need your architectural plans, site plan, BASIX certificate (if required), property title, and any other supporting documentation relevant to your development. During your initial consultation, we’ll guide you through exactly what’s required based on your project type.
How long does the CDC/CC/OC process take?
Timelines can vary based on the complexity of your project and the quality of submitted documents. For straightforward projects, a CDC can often be approved within 10 business days. Construction Certificates and Occupation Certificates may take longer depending on inspections and compliance checks. We always strive for the quickest possible turnaround.
Can Zephyr handle inspections and certifications?
Yes, Zephyr Approvals is fully licensed to act as the Principal Certifier. We manage mandatory construction inspections at key stages and issue your final Occupation Certificate upon successful completion. Our team ensures your development complies with all relevant building regulations throughout the process.
What if my project doesn’t meet all criteria?
If your development doesn’t meet specific criteria for CDC or CC approval, we’ll advise you on the next best steps. This may include modifying plans, obtaining additional reports, or exploring alternate approval pathways such as a DA. We’re here to help you navigate challenges and stay on track.
Do you work with homeowners as well as builders and architects?
Yes, we work closely with homeowners, builders, architects, and designers to ensure every project meets compliance standards. Whether it’s your first build or a large-scale development, we tailor our services to suit your needs.
What types of residential developments do you certify?
We provide certification for a wide range of residential projects, including new homes, dual occupancies, townhouses, alterations, additions, granny flats, pools, decks, and more.
