Planning to build a new home, duplex, granny flat, commercial property, or undertake alterations and additions in NSW?
Navigating building approvals and certification can be complex. Depending on your development and approval pathway, you may require a Complying Development Certificate (CDC), Construction Certificate (CC), appointment of a Principal Certifier, mandatory inspections during construction, and an Occupation Certificate (OC) before the building can be occupied or used.
At StoneyBark Certifiers, we provide professional building certification services across Sydney and NSW. We work with homeowners, builders, architects, designers, developers and other industry professionals to assess applications, undertake required inspections and provide certification services in accordance with applicable NSW legislation and the National Construction Code (NCC).
Our aim is to make the certification process clear, responsive and efficient while maintaining the independence required of registered certifiers.
What Does a Private Building Certifier Do?
In NSW, a registered certifier is an independent professional who carries out statutory certification functions relating to building and development work.
Depending on their registration and the type of development, a registered certifier may:
- Assess applications for Complying Development Certificates
- Assess applications for Construction Certificates
- Act as the Principal Certifier
- Conduct required critical stage inspections
- Assess building work against approved plans and applicable requirements
- Assess applications for Occupation Certificates
- Issue certificates where all applicable legislative requirements have been satisfied
- Identify certain non-compliances observed as part of their certification functions
A certifier’s role is independent. A certifier is not the builder, project manager or site supervisor and does not manage construction work on behalf of the owner or builder.
At StoneyBark Certifiers, we focus on providing clear certification advice and helping clients understand the documentation and certification requirements relevant to their project.
DA, CDC or Construction Certificate – What’s the Difference?
One of the most common questions we receive is:
“Do I need a DA, CDC or Construction Certificate?”
The answer depends on the type of development, the property and the applicable planning controls.
Development Application (DA)
A Development Application is generally submitted to the relevant consent authority, commonly the local council, where development consent is required.
If the DA is approved, building work covered by that consent will generally require a Construction Certificate before construction can commence.
Complying Development Certificate (CDC)
A Complying Development Certificate provides a streamlined approval pathway for development that satisfies predetermined planning and building requirements.
A CDC combines planning and construction approval into one process for eligible complying development.
Construction Certificate (CC)
Where development consent has already been obtained through the DA process, a Construction Certificate generally confirms that the detailed construction plans and specifications are consistent with the development consent and satisfy applicable building requirements before construction commences.
The appropriate pathway will depend on your individual project and site.
Complying Development Certificate (CDC)
A Complying Development Certificate can provide a streamlined approval pathway for eligible development that meets applicable NSW complying development standards.
Rather than proceeding through the traditional DA followed by Construction Certificate pathway, eligible development may be approved through a CDC.
At StoneyBark Certifiers, our CDC services may include:
- Preliminary review of the proposed development
- Assessment against applicable complying development standards
- Review of architectural documentation
- Review of engineering and supporting documentation
- Assessment against relevant NCC requirements
- Identification of additional documentation that may be required
- Determination of the CDC application
- Issue of a CDC where all applicable requirements are satisfied
Depending on the site and proposal, complying development may be available for certain types of:
- New dwelling houses
- Alterations and additions
- Secondary dwellings/granny flats
- Dual occupancies/duplexes
- Swimming pools
- Outbuildings
- Commercial or industrial development
Eligibility depends on the property, development type and applicable planning controls.
Not every property or development qualifies for CDC.
Construction Certificate (CC)
If your development has received development consent through the DA process, you will generally require a Construction Certificate before commencing building work covered by that consent.
A Construction Certificate relates to the detailed construction documentation for the approved development.
As part of the assessment, relevant documentation may be reviewed against requirements including:
- Development consent and applicable conditions
- National Construction Code
- Architectural plans and specifications
- Structural engineering documentation
- Fire safety requirements, where applicable
- Energy efficiency requirements
- Accessibility requirements, where applicable
- Other relevant statutory requirements
Where the applicable requirements have been satisfied, a Construction Certificate may be issued.
Principal Certifier Services
Before certain building work commences, a Principal Certifier must be appointed.
The Principal Certifier performs an independent regulatory role during construction.
Depending on the development, the Principal Certifier’s functions may include:
- Undertaking required critical stage inspections
- Maintaining required certification records
- Assessing matters relevant to certification
- Reviewing required documentation during construction
- Identifying certain non-compliances observed during inspections
- Assessing an application for an Occupation Certificate
- Issuing an Occupation Certificate where all applicable requirements have been satisfied
It is important to understand that the Principal Certifier does not supervise the builder or manage the construction project.
The builder remains responsible for carrying out the building work in accordance with the approved plans, applicable standards and legal requirements.
Critical Stage Building Inspections
Inspections are an important part of the NSW building certification process.
The inspections required will depend on the type and classification of the building, approval pathway and particular project.
Depending on the development, inspections may relate to stages such as:
- Excavation and footings
- Reinforcement before concrete placement
- Slab construction
- Structural framing
- Waterproofing
- Stormwater or drainage-related work where applicable
- Fire safety measures
- Other prescribed stages
- Final inspection
Not every project requires exactly the same inspections.
Your Principal Certifier can advise which inspections are required for your particular development.
Why are inspections important?
Required inspections help the Principal Certifier assess relevant aspects of the building work at prescribed stages before construction progresses further.
Builders and property owners should ensure required inspections are booked at the appropriate time.
Occupation Certificate (OC)
An Occupation Certificate is an important final stage in the certification process.
An Occupation Certificate authorises the occupation or use of a new building, or a change in use of an existing building, where the applicable requirements have been satisfied.
Before determining an Occupation Certificate application, the Principal Certifier may need to consider:
- Completion of required critical stage inspections
- Final inspection
- Required certificates and documentation
- Fire safety requirements, where applicable
- Compliance with relevant conditions of consent or approval
- Other applicable statutory requirements
Where all applicable requirements have been satisfied, the Principal Certifier may issue an Occupation Certificate.
StoneyBark Certifiers can assist clients in understanding the documentation required to progress an Occupation Certificate application.
Building Code & Compliance Reviews
Identifying potential compliance issues early can help reduce redesign, additional documentation and unnecessary delays later in the project.
StoneyBark Certifiers can review relevant documentation within the scope of our certification services against applicable requirements.
Depending on the project, this may involve consideration of:
- National Construction Code
- Building classifications
- Fire safety provisions
- Access and egress
- Accessibility requirements
- Energy efficiency requirements
- Relevant construction requirements
- Applicable approval conditions
The exact requirements depend on the building classification, proposed development and certification pathway.

Private Certifier vs Council – What’s the Difference?
Depending on the development and approval pathway, certain certification functions may be carried out by either a registered private certifier or a local council.
A private certifier may provide benefits such as:
- A dedicated certification contact
- Direct communication regarding certification requirements
- Coordinated inspection bookings
- Clear documentation requirements
- Ongoing certification services across relevant stages of the project
However, private certifiers and council certifiers must perform their certification functions in accordance with applicable NSW legislation.
A private certifier does not have discretion to approve development that fails to satisfy the applicable statutory requirements simply because they have been privately engaged.
The certifier must act independently when performing certification functions..

Frequently Asked Questions
What does a private building certifier do in NSW?
A registered private certifier performs independent statutory certification functions. Depending on their registration and appointment, this may include assessing CDC and Construction Certificate applications, undertaking required inspections, acting as Principal Certifier and assessing Occupation Certificate applications.
What is a Complying Development Certificate?
A Complying Development Certificate is a streamlined approval pathway for eligible development that meets predetermined NSW planning and building requirements.
It combines planning and construction approval for qualifying complying development.
Is a CDC faster than a DA?
The CDC pathway is designed as a streamlined approval process for eligible complying development.
However, a development must satisfy all applicable requirements to qualify. The time required will also depend on the completeness of the application and supporting documentation.
Do I need both a CDC and Construction Certificate?
Generally, no for the same building work.
A CDC combines planning and construction approval for eligible complying development.
Where a project instead receives development consent through the DA pathway, a Construction Certificate will generally be required before the approved building work commences.
When do I need a Construction Certificate?
A Construction Certificate is generally required before commencing building work that has been approved through a Development Application.
What is a Principal Certifier?
A Principal Certifier is appointed to carry out prescribed certification functions during construction, including required critical stage inspections and, where applicable, assessment of an Occupation Certificate application.
The Principal Certifier is an independent regulatory professional and does not supervise the builder.
Can my builder choose my private certifier?
For residential building work, there are important NSW requirements concerning the appointment of the Principal Certifier and the owner’s right to choose their certifier.
Speak with StoneyBark Certifiers if you need information about the appropriate appointment process for your project.
What happens if an inspection is missed?
Required inspections should be arranged before work progresses beyond the relevant stage.
A missed critical stage inspection can create significant certification issues and may affect the ability to issue an Occupation Certificate.
Contact your Principal Certifier as soon as possible if you believe an inspection has been missed.
Can a private certifier approve anything?
No.
Private certifiers must act independently and can only issue certificates where the applicable statutory requirements have been satisfied.
What is an Occupation Certificate?
An Occupation Certificate authorises the occupation or use of a new building, or a change of use of an existing building, where applicable requirements have been satisfied.
