Most of the expensive mistakes I see start before anyone lodges. The wrong pathway gets locked in, the drawings keep moving, and weeks later you’re redesigning work that was never going to fit.

Construction certificates, complying development, principal certifier inspections and occupation certificates can sit with one practice instead of being split across disconnected files.
The practice assesses class 1 and 10 buildings.
An approval pathway review can identify the pathway to investigate and the information required, without treating an enquiry as an approval or a free document assessment.
NSW Housing Pattern Book and Low and Mid-Rise Housing (LMR) work is covered as part of our certification services, including Pattern Book CDC assessment for eligible low-rise class 1 and 10 homes.
Enquiries are welcome from across the metropolitan area. Request a fee proposal and we will reply with the next step.
We also cover Low and Mid-Rise Housing (LMR) and NSW Housing Pattern Book work as part of our certification services — including Pattern Book CDC assessment for eligible low-rise class 1 and 10 homes.

As builders in Sydney we have been using Joe and the team at Exclusive for a number of years now and have always been impressed with the great level of service and attention to detail on plan reviews. Thanks for the ongoing support and I openly recommend them to anyone looking for an honest certifier.

Joseph from Exclusive Certifiers and Building Consultants could not have been more helpful to my husband and I. We had tried a number of certifiers before finding Joseph. He was always available to answer our many questions and willing to freely assist with his vast knowledge. I could not recommend this company more highly; very ethical, honest and reliable. Thank you Joseph.

I have engaged Joe through my architect as my private certifier, and Joe approved my application within a very short timeframe. He would always answer my calls, or call me back when he couldn't answer straight away. He would also go above and beyond his job duties to help his clients. Highly recommended!
A private certifier assesses building applications, carries out required inspections and issues certificates so work can legally start, continue and be occupied. They check proposed work against the National Construction Code and relevant NSW planning pathways. Exclusive Certifiers’ certification work is limited to class 1 and 10 buildings.
A Construction Certificate (CC) confirms that detailed building plans are consistent with the development consent and the National Construction Code. In most projects with development consent it is required before building work can start.
A Complying Development Certificate (CDC) is a combined planning and construction approval for development that meets the relevant state codes. Pathways include a standard CDC, the Low-Rise Housing Diversity Code and, where the design is an endorsed low-rise pattern, a NSW Housing Pattern Book CDC.
An Occupation Certificate is required before a new building, or an approved stage or part of a building, can be occupied or used. For consents granted from 1 December 2019, interim and final certificates are no longer the current general model. Staged occupation may still be available.
The principal certifier is appointed by the owner before work starts, carries out critical-stage inspections during construction and issues the occupation certificate when the work is complete and suitable to occupy or use. The builder cannot choose or influence that appointment.
The practice does not prepare DAs, design buildings or supply engineering design — independent professionals prepare those documents. Owner-side project management for class 1 and 10 programme and consultant liaison is offered separately; it is not site supervision and is not available when Exclusive Certifiers is appointed principal certifier on the same job.
