Complying Development Certificate
Complying Development Certificate.
A Complying Development Certificate confirms that a proposed development complies with specific planning controls, zoning requirements, and building standards. Once issued, the certificate provides both planning consent and construction approval, meaning building work can begin after the required notification period.
The proposed development must meet strict guidelines relating to building size, height, setbacks, landscaping, and environmental standards. The certifier will also ensure that the design complies with the National Construction Code before the certificate is granted.
Why a Complying Development Certificate Is Important
A Complying Development Certificate plays an important role in ensuring that building projects are safe, compliant, and legally approved.
Benefits of a Complying Development Certificate
Choosing a Complying Development Certificate instead of a traditional Development Application can provide several advantages for homeowners, builders, and property developers.
Faster approval times
A CDC approval is usually much faster than a Development Application, allowing construction projects to begin sooner.
Combined planning and construction approval
A CDC provides both planning consent and construction approval in a single certificate, simplifying the overall approval process.

Reduced paperwork and simplified approval
The CDC pathway involves fewer administrative requirements, making the approval process quicker and more efficient.
Clear development standards and guidelines
CDC projects follow clearly defined planning rules and building standards, making it easier to determine if a development qualifies.
Lower risk of delays during the planning process
Because the approval criteria are predefined, compliant projects are less likely to face delays or extended assessment periods.
Types of Projects That May Qualify for a CDC
Many types of developments in Sydney may be approved through the CDC pathway if they meet the required planning standards.
- New residential houses
- Granny flats (secondary dwellings)
- Home extensions and additions
- Swimming pools and outdoor structures
- Garages, carports, and sheds
- Internal alterations and renovations
- Certain commercial or industrial building works
Working with an experienced building certifier ensures your project is monitored properly from construction commencement through to final approval.

CDC vs DA: Which Approval Do You Need?
Understanding the difference between a Complying Development Certificate and a Development Application can save you months on your project timeline.
| Complying Development Certificate (CDC) | Development Application (DA) | |
|---|---|---|
| Approval Body | Private certifier (e.g. Stoneybark) | Local council |
| Timeframe | 10–20 business days | 3–12 months |
| Suitable For | Standard residential and commercial projects meeting pre-set criteria | Complex, non-standard, or heritage-sensitive projects |
| Neighbour Notification | Not required | Mandatory public consultation period |
| Approval Criteria | Predefined. Tick-box assessment against State planning codes | Merit-based. Council planners assess subjectively |
| Risk of Delays | It is low if your plans meet the standards, approval must be issued | It is high if subject to council backlogs, objections, and design requests |
| Cost | Generally lower and more predictable | Generally higher due to council fees and extended timeframes |
| Flexibility | It is less flexible as the project must meet set standards | It is more flexible as non-standard designs can be assessed |
If your project meets NSW State planning standards, a CDC is almost always the faster and more cost-effective route. Stoneybark can assess your plans and confirm CDC eligibility before you commit to either pathway.
