Common Questions
What you need to know about exempt development
What if my project doesn't qualify as exempt?
If your project doesn't meet the exempt development criteria, you'll likely need either a Complying Development Certificate (CDC) or a Development Application (DA). A CDC is faster and can be approved by a private certifier, but has stricter rules. A DA goes to council and takes longer, but offers more flexibility. We can help you work out which pathway suits your project.
Can I still build if I'm in a heritage area?
Being in a heritage conservation area doesn't mean you can't build — it just means exempt development rules don't apply to most structures. You'll usually need a DA, but councils are often supportive of well-designed additions that respect the heritage character. The key is getting the design right from the start.
What about bushfire prone land?
Bushfire prone land has extra requirements, but many projects are still possible. Some exempt developments (like small sheds) may still be allowed with specific construction standards. Larger projects will need a bushfire assessment. The rules depend on your bushfire attack level (BAL) — we can help you understand what applies to your site.
Is this tool legally binding?
No — this tool gives you a preliminary indication based on planning constraints. Exempt development is "self-assessed," meaning you (or your builder) are responsible for ensuring all criteria are met. If you're unsure, it's worth getting professional advice before starting work. We're happy to do a detailed review if you need certainty.
What's the difference between exempt and complying development?
Exempt development requires no approval at all — if you meet all the criteria, you can just build it. Complying development needs a certificate from a certifier, but it's much faster than a DA (usually 10-20 days). Think of it as a middle ground: more flexibility than exempt, less process than a DA.
Do I need a builder or can I do the work myself?
That depends on the work. In NSW, owner-builders can do work on their own home, but there are licensing requirements for work over $10,000. Structural work, plumbing, and electrical need licensed tradespeople regardless. Exempt development doesn't change these rules — it just means you don't need planning approval.
