Step-by-Step Guide to Getting Council Approval for a Renovation in NSW

Renovating your home in NSW can feel overwhelming – not because of the tiles and benchtops, but because of the paperwork and approvals.

The good news: once you understand the steps, the process is a lot less scary. This guide walks you through the typical journey a mum-and-dad renovator takes from first sketch to council approval.

Step 1: Clarify Your Brief and Budget

Before you talk to council, you need to be clear on:

• Why you’re renovating (more bedrooms, better living space, accessibility, future resale)
• How much you’re roughly prepared to spend
• Must-haves vs nice-to-haves (extra bathroom, bigger kitchen, better indoor-outdoor flow, etc.) A short written brief helps everyone – architect, designer, builder, planner and ultimately council – understand what you’re trying to achieve.

Step 2: Get a Site Check and Feasibility

This is where you or your design professional:

• Confirm the zoning of your property

• Check the relevant planning controls (height, floor space, setbacks, private open space, heritage, flooding, bushfire, etc.)

• Identify possible approval pathways – DA, CDC, exempt development or a mix At this stage you want answers to questions like:

• Is my idea even possible here?

• Are there any big red flags (heritage, easements, significant trees)?

• Are we aiming for DA, CDC, or both (Plan A / Plan B)?

Step 3: Concept Design

Once feasibility is done, your designer or architect prepares concept plans, usually including:

• Floor plans
• Basic elevations
• A sense of massing (how the extension sits on the site) For mums and dads, this is the fun part – you start to see how your renovated home could actually work.

Good concept design will already respect key controls like height, bulk, overshadowing and privacy, so that you’re not setting yourself up for a battle later.

Step 4: Pre-Lodgement Advice (Optional but Helpful)

Many councils offer pre-lodgement meetings or written advice.

Your designer/planner can:

• Present the concept to council
• Ask for feedback on any sensitive issues
• Clarify whether council sees any “show-stoppers” This isn’t mandatory, but it can save time later by ironing out issues before you lodge.

Step 5: Detailed DA/CDC Documentation

Approvals need more than just pretty plans. For a typical renovation you may need:

• Architectural drawings (plans, elevations, sections, roof plan, site plan)
• Shadow diagrams and privacy diagrams (for upper storeys)
• BASIX certificate (for certain dwellings/works)
• Stormwater / drainage design
• Bushfire or flood reports, if applicable
• A Statement of Environmental Effects (for a DA) explaining how the proposal meets the controls and addresses any variations Your design team will coordinate these documents and consultants so that the package is complete and consistent.

Step 6: Lodging the Application

Depending on the path:

• For a DA:Lodge through the planning portal (and pay fees).

• Council does a completeness check.

• Neighbours are usually notified and can comment.

• For a CDC:Lodge with a council certifier or a private certifier.

• They check your project strictly against the relevant codes.

Make sure your name, contact details and builder (if known) are all correct – simple admin errors can cause delays.

Step 7: Assessment and Possible Requests for Information

During assessment, council or the certifier may ask for:

• Clarifications or extra notes on the plans
• Minor changes to address overshadowing, privacy, trees, setbacks or design issues
• Updated reports from specialists Don’t panic – requests for information are normal. Respond promptly and have your designer handle technical matters so you don’t get lost in jargon.

Step 8: Determination – Approval (Hopefully!)

At the end of the assessment you’ll receive:

• A consent / certificate (DA consent or CDC)

• Conditions of approval – these are important Conditions often cover things like:

• Construction hours

• Tree protection

• Materials and finishes

• Privacy screens or window changes

• Stormwater requirements Your builder and designer need to understand these conditions and factor them into the construction drawings and contract.

Step 9: Construction Certificate and Building

For most projects, you’ll still need a Construction Certificate (CC) or the equivalent building approval before you start work. This confirms that the detailed construction drawings comply with the Building Code and relevant standards.

Once your CC or CDC is in place, you can arrange:

• Builder engagement and contract
• Insurances
• Site set-up and the first inspection

Key Tips for a Smooth Council Approval

• Get advice early – a quick feasibility check can save months.
• Be realistic about what your site can handle.
• Respond quickly to council/ certifier queries.
• Lean on your professionals – architect, building designer, planner and certifier do this all the time. With the right team and a clear process, council approval doesn’t have to be a nightmare – it’s just another step between you and your renovated home.
