How to Get a Large Shed Approved in NSW

Writer's picture: Richard MeadRichard Mead

A large shed is typically a versatile structure with a span of 12 metres or more, designed to serve various purposes such as a home gym, guest house or creative studio.


Whether you're planning to build a spacious shed for storage or convert one into a functional space like a home office, the approval process in New South Wales (NSW) requires careful planning and adherence to local regulations.


Here's everything you need to know about getting a large shed approved in NSW.


Step 1: Understand the Definition and Purpose of a Large Shed


Large sheds are more than just storage solutions. People use them for a variety of purposes, including:


  • Entertainment areas like "man caves" or hangout spaces.

  • Gardening headquarters or micro-farming barns.

  • Creative studios, music rooms, or home gyms.

  • Pool houses or guest accommodations.


These multi-functional spaces must comply with specific regulations depending on their location, size, and intended use.

Step 2: Determine If Your Shed Qualifies for Exempt or Complying Development


Exempt Development


In some cases, you may not need council approval to build your shed. If it qualifies as exempt development, it must meet strict requirements, including:


  • Maximum height and floor area restrictions.

  • Compliance with setback requirements from boundaries, easements, or drains.

  • Adherence to specific zoning conditions as outlined in the Local Environmental Plan (LEP) or Development Control Plan (DCP).


Tip: Use the NSW Planning Portal or consult StraightLine Planning to determine if your shed meets exempt development criteria.


Complying Development Certificate (CDC)


If your shed does not qualify as exempt development, a CDC may provide a faster approval pathway compared to a full Development Application (DA).


  • The shed must comply with pre-determined state-wide criteria for setbacks, height, and materials.

  • Engaging a private certifier can streamline the CDC process, typically resulting in approval within 10-20 days.


Step 3: Prepare the Necessary Documentation


Regardless of the approval pathway, you’ll need detailed documentation to support your application. This typically includes:


  1. Site Plans: Showing the shed’s location on your property, setbacks, and compliance with council requirements.

  2. Engineering Drawings: Including specifications for the shed’s structure, footings, or slab.

  3. Elevations and Dimensions: Detailing the shed’s height, materials, and visual appearance.

  4. Stormwater Management Plan: Addressing how rainwater will be managed, especially if the shed is near drains or easements.

  5. BASIX Certificate: If the shed is intended as a habitable space, energy and water efficiency compliance will be required.


For sheds in heritage conservation areas, additional documentation such as material specifications and heritage reports may also be necessary.





Step 4: Submit Your Application


Development Application (DA)


If neither exempt development nor a CDC applies, you'll need to submit a DA to your local council.

  • Prepare all forms and documentation.

  • Pay the application fee, calculated based on the estimated cost of the shed.

  • The council will assess your application, notify neighbours, and allow for public comments.


Approval Timeline: A DA typically takes 40-90 days for council determination, depending on the complexity of the project.


CDC Submission


For a CDC, submit your plans to a private certifier or council. The process is quicker as it skips neighbour notifications and focuses solely on compliance with state regulations.


Step 5: Address Specific Challenges


Building Materials and Heritage Requirements


In Heritage Conservation Areas, councils often require sheds to blend with the surrounding aesthetic. While cost-effective materials like Colorbond are common, some councils may insist on timber construction with heritage features.


Solution: Work with a town planner to negotiate material choices that satisfy council requirements while maintaining affordability.


Location Challenges


If the only feasible location for your shed is near a council drain or easement, you’ll need to provide a comprehensive survey and stormwater management plan.


Tip: Engage a qualified surveyor early to identify potential issues and propose solutions, such as rerouting stormwater or adjusting the shed’s placement.


Conversion to Habitable Use


If you plan to convert your shed into a granny flat or guest house, the rules are more stringent. You’ll need to:


  • Comply with the Building Code of Australia (BCA) for habitable spaces.

  • Address monetary contributions or development levies.

  • Ensure the design respects neighbours’ privacy and amenity.


Tip: Clearly differentiate between a storage shed and a habitable building in your application.

Step 6: Post-Approval Compliance


Once your shed is approved, you’ll need a Construction Certificate before beginning work.


Additionally:


  • Comply with conditions outlined in the approval, including construction hours, noise, and dust control.

  • Ensure your builder adheres to approved plans and uses materials as specified in the documentation.


Key Considerations


Floor Space Ratio (FSR)


Councils often limit the total floor area of structures on a lot. Ensure your shed’s size doesn’t exceed the FSR specified in the LEP or DCP for your property.


Stormwater Management


Proper drainage is critical to prevent waterlogging or runoff issues. Include a drainage plan that demonstrates compliance with Australian Standards.


Neighbour Objections


Even if your shed meets all technical requirements, objections from neighbours regarding overshadowing or visual impact could delay approval. Address these concerns proactively by including privacy measures such as landscaping or fencing.


Why Engage a Town Planner?


Navigating the complex approval process for a large shed can be daunting, especially with varying requirements across councils. A professional town planner can:


  • Advise on the most suitable approval pathway (DA or CDC).

  • Prepare detailed documentation, ensuring compliance with all relevant standards.

  • Negotiate with council and neighbours to minimise objections.
