Building a Backyard Shed or Workshop? What to Know About Council Approval in NSW

For a lot of blokes, a proper shed is the dream. Somewhere to keep the tools, work on projects, store the gear or just crack a cold one away from the house.

But before you order a kit or pour a slab, there's one question worth answering first: do you need council approval? Getting it wrong can mean fines, orders to modify the structure or problems when you come to sell.

For anything beyond a basic garden shed, talking to an outdoor building drafter in Sydney early can help you understand your options and get the right plans in place from day one.

Does Every Shed Need Approval?

Not always. In NSW, some smaller outbuildings can be built as exempt development, which means no formal approval is needed, as long as the structure meets a strict set of criteria.

Those criteria typically cover things like size, height, setbacks from boundaries, materials and where the structure sits on the property. Restrictions may also apply if your home is heritage-listed or in a bushfire-prone or flood-prone area.

If your shed or workshop doesn't meet every requirement, you'll likely need either a complying development certificate (CDC) or a development application (DA) through council.

Common Backyard Projects That Need Planning

Sheds aren't the only outdoor structures that can trigger approval requirements. Other popular projects include:

• Workshops and home offices
• Garages and carports
• Pergolas and patio covers
• Outdoor entertaining areas and alfresco roofs
• Retaining walls
• Cabanas and pool houses

The bigger and more permanent the structure, the more likely it is that plans and approvals will be needed.

6 Things to Consider Before You Build

1. Size and Height

It's tempting to go big, especially if you want room for a car, a workbench and a few toys. But size and height are two of the main factors that decide whether a structure needs approval.

Work out what you actually need before settling on a design.

2. Setbacks and Boundaries

How close your shed sits to the fence line matters. Building too close to a boundary can affect your neighbours and your approval pathway, so check your property's boundaries carefully before choosing a location.

3. Easements and Services

Sewer lines, stormwater pipes and easements often run through Sydney backyards. Building over them can be restricted and may cause problems later if access is needed for maintenance.

A dial-before-you-dig check and a look at your property's survey or plans can help identify what's underground.

4. Drainage

A new roof means more rainwater to manage. Make sure water from the shed is directed appropriately and doesn't flood your yard or flow into a neighbour's property.

5. Power and Plumbing

If you want lights, power points, air conditioning or a sink in your workshop, plan for it early. Electrical work must be done by a licensed electrician, and plumbing by a licensed plumber.

6. How You'll Use It

There's a big difference between a storage shed and a space you plan to spend a lot of time in. Using an outbuilding as a bedroom, studio or habitable space generally involves different building requirements and approvals than a standard shed.

If you're thinking of turning it into an office, gym or granny flat later, factor that into your planning now.

What Happens If You Build Without Approval?

Building without the required approval can lead to council compliance action, which may include orders to modify or remove the structure. It can also create problems when selling, as buyers and their solicitors often check approvals during due diligence.

In some cases, unapproved work may affect insurance claims. It's far easier to get things right at the start than to fix them later.

How a Draftsman Can Help

A draftsman can prepare the drawings needed for your project, including site plans, floor plans, elevations and sections. These plans show exactly what you intend to build and where it will sit on the property.

They can also help you understand which approval pathway may apply and prepare documentation for a CDC or DA, working alongside certifiers, engineers and your builder where needed.

If you're unsure what your project requires, an experienced council approval draftsman can help you plan a design that suits your site and gives your application the best chance of moving smoothly.

Final Thoughts

A backyard shed or workshop can be one of the best upgrades a bloke can make to his home. But a little planning goes a long way.

Check whether your project needs approval, think carefully about size, location, drainage and services, and get proper plans drawn up. That way, you'll spend more time enjoying the shed and less time dealing with council.
