Do I Need Architectural Plans For Both CDC and DA Approvals?

Yes, both CDC and DA applications require detailed architectural plans to be submitted for assessment.

But the type of information required, and who assesses it, varies between the two processes.

At Town Planning Sydney, we prepare accurate, compliant plans tailored to each NSW planning pathway.

Here’s what you need to know before you lodge your application.

1. All building approvals start with architectural drawings

Whether you go through a private certifier or local council, you must provide clear, scaled plans.

These drawings explain the size, layout, structure and design of the proposed building work.

We help clients prepare architectural drawings that meet the specific requirements of either DA approval or CDC.

2. DA applications need plans that match local council rules

When you lodge a development application with council, your plans must respond to the zoning and planning controls set out in the Local Environmental Plan and Development Control Plan.

This includes site coverage, setbacks, landscaping, floor space ratio and design guidelines.

Our planning consultants work with our drafting team to make sure these rules are embedded into the drawings before submission.

In Hornsby, we revised a balcony and roof height after identifying non-compliance with rear setback rules.

3. CDC approvals require strict compliance with state codes

If you’re applying for Complying Development, your architectural plans must meet the exact standards of the NSW Housing Code.

There is no flexibility or discretion. Our team prepares CDC drawings that show all required information, including setbacks, private open space and building envelope.

For a duplex in Georges River, we adjusted the internal layout and roof form to stay within height and FSR limits under CDC.

4. Supporting documents rely on accurate plans

Your Statement of Environmental Effects, shadow diagrams, stormwater plans and BASIX reports all rely on the architectural drawings being correct.

Errors or inconsistencies between documents cause delays or rejections. We coordinate these documents in-house to ensure they match the approved plans.

This streamlined approach helps reduce back-and-forth with council approval teams.

5. Revisions cost time and money, get it right the first time

Submitting the wrong set of plans, or leaving out key information, often results in requests for changes.

This leads to added drafting fees, council delays and unnecessary frustration. We help avoid this by reviewing each drawing against the approval pathway.

In Camden, our early intervention saved a client four weeks by correcting height errors before submission.

6. One firm to manage planning and drawing saves you stress

Working with a company that offers both drafting and town planning under one roof ensures your plans meet both design and legal requirements.

Town Planning Sydney offers seamless preparation of plans and documents for both CDC and development application processes.

This gives you the best chance of success, whether you’re building a new home, adding a storey or extending your property.
