Building a new home is one of the biggest investments you will make, and getting the certification right from the start is essential. Whether your new home is approved via a Complying Development Certificate or a Development Application with Construction Certificate, Sydney Wide Certifiers provides a complete certification service — from initial approval through every mandatory inspection to the final Occupation Certificate. We work with owner-builders, project home companies and custom builders across Sydney.

What's Included

Assessment and issue of Complying Development Certificates for new dwellings under the General Housing Code of the Codes SEPP, including single and two-storey homes, where the proposal meets all applicable development standards.

Issue of Construction Certificates for DA-approved new homes, with thorough assessment against BCA/NCC Volume Two (residential) provisions covering structure, fire safety, damp and weatherproofing, health and amenity, and energy efficiency (BASIX).

Principal Certifier services for the full construction phase, including all critical-stage inspections from excavation through to final completion.

Review of structural engineering designs for footings, slabs, retaining walls, framing and roof structures against the relevant Australian Standards (AS 2870, AS 1684, AS 4100, AS 3600).

BASIX compliance verification to confirm the design achieves the required water, thermal comfort and energy targets for the climate zone.

Issue of the final Occupation Certificate once all inspections and conditions are satisfied, enabling you to move into your new home.

FAQ

Frequently Asked Questions

Can my new home be approved as Complying Development?
Many new homes in Sydney can be approved as complying development under the General Housing Code in the Codes SEPP, provided the site and the proposed dwelling meet every applicable development standard. The standards cover matters such as lot size, building height (typically up to 8.5 metres), setbacks from boundaries, site coverage, landscaped area, floor space ratio, car parking, private open space and solar access to neighbouring properties. Sites that are heritage-listed, in certain flood zones or bushfire flame zones, or subject to other specific exclusions may not be eligible. Our preliminary CDC assessment service can confirm whether the CDC pathway is available for your site.
What does BASIX mean for my new home?
BASIX (Building Sustainability Index) is a NSW Government policy that requires all new residential developments to meet specific sustainability targets for water efficiency, thermal comfort and energy use. A BASIX certificate must be obtained before a CDC or CC can be issued for a new home. The BASIX certificate sets out specific commitments — such as insulation levels, glazing types, water tank sizes, efficient fixtures and sometimes solar photovoltaic systems — that must be incorporated into the design and constructed on site. Compliance with BASIX commitments is verified during the certification and inspection process.
How long does the entire certification process take for a new home?
The timeline depends on the approval pathway. A CDC can be issued within 10 business days of a complete application. A CC typically takes 5–10 business days once all documentation is in order. The inspection phase then runs concurrently with construction, which for a typical new home in Sydney ranges from 6 to 12 months depending on the builder and complexity. The final Occupation Certificate is usually issued within a few days of the final inspection being satisfactorily completed. The key to a smooth timeline is submitting complete, compliant documentation at each stage — our team provides checklists and guidance to ensure nothing is missed.
