Granny Flat Approvals in NSW: What You Need to Know

Granny flats, also known as secondary dwellings, are one of the most popular forms of small-scale housing in NSW. They offer flexibility for families, rental income for investors and a practical solution for downsizers.

However, before construction can begin, you’ll need to go through the correct town planning and approval process.

There are two main pathways for granny flat approvals in NSW: a Development Application (DA) through council or a Complying Development Certificate (CDC) through a private certifier.

Both options require compliance with NSW planning legislation, zoning rules and building regulations.

To be eligible for a granny flat under CDC, the property must be in an R1, R2, R3 or RU5 zone, be at least 450sqm in area and have a minimum 12m street frontage.

If your site doesn't meet these requirements, a DA is still possible with the right planning advice.

We assess your site, explain the most efficient pathway, and prepare all necessary documentation.

This includes a Statement of Environmental Effects, architectural plans, site analysis and any required specialist reports.

If your project includes elements like reduced setbacks or parking variations, we can help prepare a Clause 4.6 variation request as part of the DA submission.

We also assist with council submissions for secondary dwellings, whether on standard residential lots or more complex sites.

Councils vary in how they interpret their Development Control Plans (DCPs), so working with a planner who knows local policy can save weeks of unnecessary back-and-forth.

Many clients come to us asking how to get a DA approved in NSW for their granny flat.

The key is preparing a complete, compliant application that addresses all planning controls and presents your proposal clearly.

Councils are more likely to approve a well-supported submission backed by professional planning consultants.
