Does My Renovation or Extension Likely Need Exempt, CDC or DA Approval?
Use SCE Corp’s approval pathway tool NSW page to get rough early guidance on whether your renovation, extension or related works are more likely to be exempt development, complying development, a development application, or a matter needing specialist review.
This tool is NSW-only and is for early pathway guidance only. It is not legal advice, certification or authority advice. Final outcomes depend on the site, planning controls, building class, heritage context, hazards and the exact scope of work.
What This Approval Pathway Tool NSW Covers
This page is designed to help users compare likely NSW approval pathways for common project types before going further with design, consultant engagement or formal application steps.
- Renovations and internal alterations
- Extensions and additions
- Decks, pergolas, outbuildings and related residential works
- Façade and cladding-related changes
- Secondary dwelling and granny flat relevance
- Heritage, strata and hazard-triggered red flags
How to Use the Output Properly
This tool gives a likely pathway only. It should not be relied on as formal planning, legal, certification, council or private certifier advice.
How This Approval Pathway Tool NSW Works
This approval pathway tool NSW page is designed to distinguish likely low-impact works from projects that are more likely to need complying development, a development application or specialist planning review. In NSW, exempt development is for very low-impact works that meet all relevant standards; complying development is a fast-tracked approval pathway for straightforward development; and local development generally proceeds through a DA where consent is required. These categories are used here as rough guidance only.

Common Approval Pathway Triggers in NSW
Low-impact works that meet all relevant standards may be exempt. Straightforward development that meets prescribed requirements may be eligible for CDC. Larger, more visible, more constrained or more site-sensitive projects often move toward DA or specialist review.
- Heritage and conservation context can quickly change the likely pathway.
- New floor area, roofline changes and visible external works often push a matter beyond simple low-impact treatment.
- Hazard overlays, strata/common property issues and mixed scopes often justify more detailed review.
- Secondary dwelling and granny flat projects frequently need more targeted pathway checking than basic renovation work.
Frequently Asked Questions
1. Is this approval pathway tool NSW page formal planning advice?
No. It is a rough NSW pathway guide only and should not be treated as legal, certification, council or planning advice.
2. Can minor renovation work be exempt development?
Sometimes yes, if the work is very low impact and meets all relevant standards. But that depends on the actual project, site and controls.
3. When is CDC more likely?
CDC is more likely where the project is straightforward and can satisfy the relevant complying development pathway requirements, but it is not available in every case.
4. When is a DA more likely?
A DA becomes more likely where the works are larger, more visible, more constrained, more site-sensitive or do not fit an exempt or complying development pathway.
5. What if my project involves heritage, hazards or strata issues?
Treat the pathway more cautiously. Those triggers often justify more detailed project-specific review before relying on a likely pathway.
6. Does this tool cover granny flats and secondary dwellings?
It can flag that those projects need more specific review, but secondary dwelling and granny flat pathways often need more targeted assessment than standard renovation work.
7. When should I contact SCE?
Contact SCE when you need project-specific guidance, scope review, a likely next-step recommendation or help coordinating the right consultant or approval pathway inputs.
