Class 2 - Residential
High-Rise Residential Towers
Approvals typically in ~35 days
Your new home. Approved and ready to build.
"Council told us our project was non-complying and we would need a DA - an 18-month process. Our certifier approved it as CDC in 12 days."
In NSW, you cannot legally begin construction on a new home without either a CDC or a CC - and every day waiting costs you in finance and holding charges.
- CDC issued privately - no council, no public exhibition period
- CC issued with full BCA and NCC compliance review in one step
- BASIX certificate, soil report, and engineering checked before you mobilise

New home certification - your questions answered.
Yes, if your site and design qualify for CDC. A CDC can avoid the full DA process, but NSW Planning Portal, notification and other approvals may still apply.
A CDC combines planning and construction approval for eligible work. A CC is construction approval issued after a DA has already been approved.
We typically issue single-dwelling CDCs within 10-14 business days after receiving complete and compliant documents. Timing depends on site constraints, notifications and further information.
BASIX is a NSW sustainability certificate covering water, energy and thermal performance. You generally need it for new residential development.
Usually, yes. A soil or geotechnical report helps the engineer design suitable footings for the site.
