How to Get a Backyard Studio Approved in NSW

Writer's picture: Mikal JensenMikal Jensen

A backyard studio is a versatile, standalone structure in your backyard designed for uses like a home office, art studio or guest room, offering additional space without major renovations.


Getting approval in NSW typically involves either a fast-track Complying Development Certificate (CDC) or a more detailed Development Application (DA), depending on the size, design, and compliance with local council regulations.


It’s an increasingly popular solution for homeowners seeking extra room without major renovations. However, before building a backyard studio in NSW, you need to navigate the planning and approval process to ensure compliance with local regulations.


Approval Pathways: CDC vs DA


In NSW, there are two primary ways to get your backyard studio approved: a Complying Development Certificate (CDC) or a Development Application (DA). Each process has its criteria, benefits, and considerations.

Complying Development Certificate (CDC)


A CDC is a fast-track approval process that bypasses council and involves assessment by a private certifier. This is the preferred route if your backyard studio meets specific pre-set criteria, including:

  • Minimum Lot Size: Your property must be at least 450m².

  • Street Frontage: A minimum of 12m is required.

  • Design and Site Compliance: The studio must adhere to design standards, including setbacks, height limits, and open space requirements.


To proceed with a CDC:


  1. Review the NSW Affordable Housing SEPP guidelines to confirm eligibility.

  2. Engage a private certifier to assess your proposal.

  3. Submit detailed documentation, including site plans and compliance reports.

  4. Receive approval, often within 20 days, and start construction.


Development Application (DA)


If your studio doesn’t meet CDC criteria, a DA is required. This process is more detailed and involves lodging an application with your local council. Key steps include:


  1. Reviewing the Local Environmental Plan (LEP) and Development Control Plan (DCP) for your council area.

  2. Preparing documentation such as site plans, elevation drawings, and a BASIX Certificate for sustainability compliance.

  3. Submitting the application and waiting for council assessment, which can take 40–90 days.

  4. Addressing public notifications and potential objections.


While a DA takes longer, it allows greater flexibility for unique designs or properties in areas with specific constraints, such as bushfire zones or heritage overlays.





Key Considerations for Approval


1. Is It Habitable?


Defining your backyard studio's use is crucial for approval. If it includes a kitchen or kitchenette, it may be classified as a secondary dwelling, requiring additional approvals and compliance with stricter regulations. To maintain its classification as a studio:


  • Clearly define the purpose as non-habitable, such as an office, art studio, or guest room.

  • Avoid installing facilities like full kitchens that suggest it will be used as a separate dwelling.


2. Defining the Development


A Preliminary Planning Report from an expert town planner can help determine the best classification for your studio. Engaging a consultant ensures your proposal aligns with council expectations while maximising your development potential.


They can also explore whether modifications to your design could achieve an even better outcome than a standard studio approval.


3. Residential Amenity


Backyard studios must consider their impact on neighbours. To minimise objections and ensure approval:


  • Privacy: Position windows and entryways to avoid overlooking neighbouring properties.

  • Stormwater Management: Address drainage issues to prevent water runoff affecting neighbouring yards.

  • Setbacks: Comply with minimum setback requirements to maintain open space and neighbourhood harmony.


Documentation and Planning Essentials


Whether pursuing a CDC or DA, the following documentation is typically required:


  1. Site Plans and Elevations: Detailed drawings showing the location, size, and design of the studio.

  2. BASIX Certificate: Demonstrating compliance with sustainability standards for energy and water efficiency.

  3. Technical Reports: Depending on your property, you may need reports addressing:

    • Stormwater drainage

    • Traffic impacts (if parking is included)

    • Bushfire risks (for properties in bushfire-prone areas)

  4. Neighbour Consultation (if DA): Engage neighbours early to address concerns and minimise objections during the public notification process.


Tips for a Smoother Approval Process


  • Engage Professionals Early: A town planner can assess your property and proposal to determine the best approval path, saving you time and resources.

  • Work with the Right Certifier or Architect: Ensure your team is familiar with NSW state and local requirements to avoid delays or redesigns.

  • Plan for Parking: If the studio includes parking, consider whether it meets council standards or if alternative contributions to public infrastructure might be required.

  • Understand Appeal Rights: If your DA is rejected, you have the option to appeal the decision through the NSW Land and Environment Court.
