Complying Development Certificate Checklist: What You Need to Know

If you're planning to build a new home, add a secondary dwelling or make alterations and additions to an existing residence in NSW, you may be able to apply utilising the Complying Development Certificate (CDC) process.

We've compiled a comprehensive checklist outlining the essential documents you’ll need to lodge a CDC application, along with additional requirements that may apply depending on your site conditions.

Essential Documents for Lodging a CDC Application

Before your application can be processed, you'll need to gather the following key documents:

1. Application Form

A completed CDC application form, signed by all property owners, must be submitted.

2. Architectural Plans

Your project requires professionally drafted plans, including:

• Site plan

• Floor plan

• External elevations

• Section plan

• Construction details

• CDC building envelope

These drawings ensure an accurate assessment of the proposed development. Town Planning Sydney can assist by providing these.

3. Title Search, Deposited Plan & 88B Instrument

A Title Search confirms ownership, while the Deposited Plan (DP) and 88B Instrument identify any restrictions or easements on the property.

4. Section 10.7 Planning Certificate

This certificate outlines zoning details, land-use permissions, and any constraints impacting the property.

5. Structural Engineering Plans

Endorsed by a Structural Engineer, these plans detail key structural components, including slab and/or piers, and must incorporate soil classification results.

6. Stormwater Management Plan

This plan illustrates the placement of downpipes, rainwater tanks, and designated discharge points, ensuring proper stormwater drainage.

7. Local Water Authority Approval

Approval from your local water provider is required to confirm compliance with infrastructure regulations.

8. Building Specifications

A detailed statement specifying the quality standards for materials and workmanship used in construction.

9. Section 138 Driveway Approval

For projects involving a driveway crossing over a public road or nature strip, council approval under Section 138 is required.

10. BASIX Certificate (Building Sustainability Index)

A BASIX certificate is mandatory for:

• New dwellings

• Renovations exceeding $50,000

• Swimming pools with a capacity of over 40,000L

This certificate outlines energy and water efficiency measures for your project.

11. Long Service Levy Receipt

For projects valued at $250,000 or more, a Long Service Levy must be paid (0.25% of the total cost). A payment link will be provided once the CDC application is lodged.

Additional Documents That May Be Required

Depending on the location and characteristics of your property, the following extra documentation may be necessary:

Bushfire Attack Level (BAL) Certificate

If the property is in a Bushfire Prone Area, a BAL Certificate issued by a certified Bushfire Consultant or Council is required. This document confirms that the project meets the required bushfire safety standards (BAL29 or lower).

Flood Certificate

For properties within a Flood Prone Area, a Flood Certificate from Council or an Engineer must confirm compliance with CDC requirements.

Geotechnical Report (Landslip Prone Area)

If the land is identified as a Landslip Prone Area, a Geotechnical Report will outline additional construction or engineering requirements.

Pre-Construction Requirements

At least two days before construction begins, the following additional documents must be provided:

Principal Contractor Details

You must confirm whether an Owner Builder Permit or a Licensed Builder will be overseeing the project:

• Owner Builder: If the total project cost exceeds $10,000, an Owner Builder Permit must be obtained from Service NSW.

• Licensed Builder: If a contracted builder is in charge, they must be licensed to carry out all required work. For contracts exceeding $20,000, Home Builders Compensation Fund Insurance is also required.

Council Contributions

Some councils charge local development contributions based on the scale or cost of the project. If applicable, these fees will be outlined during the CDC assessment process.

Security Bonds

Certain councils require a refundable security bond to cover potential damage to public assets (such as footpaths and gutters) during construction. If applicable, this will be confirmed during the CDC approval process.

Final Thoughts

A Complying Development Certificate (CDC) provides a faster and more streamlined approval process for residential projects in NSW. However, ensuring that you have the correct documentation from the outset can save time and prevent unnecessary delays.

For expert guidance on your CDC application, consult a Town Planning Sydney to confirm which documents apply to your project.
