CDC vs DA: Which Pool Approval Do You Need in NSW?

Understanding Your Pool Approval Options in NSW

Every inground swimming pool in NSW requires approval before construction can begin. As a Greater Sydney homeowner, you have two main pathways: a Complying Development Certificate (CDC) or a Development Application (DA) to your local council.

For the vast majority of standard fibreglass pool installations in Greater Sydney, the CDC pathway is the clear recommendation — and this guide explains exactly why.

What is a CDC?

A Complying Development Certificate is a fast-track approval pathway for development that meets pre-set standards defined in the NSW State Environmental Planning Policy (Exempt and Complying Development Codes) 2008 — known as the Codes SEPP.

The key difference from a DA is that a CDC is assessed and issued by a private certifier (also called a Principal Certifier), not by your local council. This removes council from the process entirely, resulting in:

• Faster approvals — typically 10–20 days
• More predictable outcomes — pass/fail against objective standards
• Lower costs — private certifier fees are generally lower than DA fees

When Can You Use CDC for a Pool?

Under Clause 3.28 of the NSW Housing Code, a swimming pool can be approved as complying development if it meets all of the following:

Most standard Greater Sydney residential properties — particularly in newer estates like Gregory Hills, Oran Park, Gledswood Hills, Harrington Park, and Leppington — will easily meet these requirements.

When is a DA Required?

A Development Application to council is required when your property or proposed pool does not meet the CDC standards. Common situations include:

Heritage properties: If your home is in a heritage conservation area or is listed as a heritage item, a DA is required. This is more common in older parts of Greater Sydney.

Setback issues: If your block is too narrow to achieve the 1-metre setback from all boundaries, you'll need a DA. This is sometimes an issue with smaller or irregular-shaped blocks.

Flood or bushfire zones: Properties in flood planning areas or bush fire prone land may require a DA if they can't meet the relevant provisions.

Exceeding site coverage: If adding a pool would push your total site coverage over the maximum permitted under your local LEP, a DA is required.

The DA Process: What to Expect

If a DA is required, the process involves:

1. Preparing a full development application with architectural plans, site analysis, and supporting documentation

2. Lodging the application through the NSW Planning Portal

3. Council assessing the application — typically 3–6 months, sometimes longer

4. A notification period where neighbours can comment

5. Council issuing a determination (approval or refusal)

The DA process is significantly more time-consuming, expensive, and uncertain than CDC. If there's any way to design your pool to meet CDC standards, it's strongly recommended.

Our Recommendation

For most Greater Sydney homeowners: pursue CDC. Work with your pool installer and a private certifier to confirm your property's eligibility early in the process. A good installer will know the CDC requirements inside out and will design your pool to comply.

If your property genuinely requires a DA, factor in the additional time (3–6 months) and cost when planning your project timeline.
