The short version
In NSW, a house demolition generally needs approval. There are three possibilities:
- Exempt development — no approval needed, for certain minor structures meeting specific conditions.
- Complying development certificate (CDC) — a fast-track approval from an accredited certifier or council, where the proposal meets predetermined standards.
- Development application (DA) — merit assessment by council against its planning controls.
Which one applies is decided by the property and the proposal. Not by what you would prefer.
Complying development
The State Environmental Planning Policy (Exempt and Development Codes) sets out codes under which development can be approved as complying development. Demolition of many dwellings can be approved this way.
How it works: a certifier checks the proposal against the standards. If it meets them, the certificate is issued. There is no merit debate and no neighbour submission process of the kind a DA has, though notification requirements apply.
Why it is quicker: fixed standards, defined timeframes, and a choice of certifier.
When it is not available: where the property or proposal falls outside the standards or is excluded — most commonly because of heritage.
Development application
Council assesses the proposal against its local environmental plan (LEP) and development control plan (DCP), and considers submissions from neighbours where the application is notified.
Why it takes longer: merit assessment, notification periods, possible requests for more information, and council workload.
When it is required: heritage items, many heritage conservation areas, sites excluded from complying development, and proposals that do not meet the codes.
What pushes a Sydney demolition to a DA
Heritage
The single biggest factor. Sydney has extensive heritage conservation areas — across much of the Inner West, Paddington and Woollahra, parts of Randwick and Waverley, Ku-ring-gai, parts of Hornsby, Parramatta, the lower North Shore and elsewhere.
Where a house is a heritage item, complying development for demolition is generally not available. Where a house sits in a heritage conservation area, demolition commonly needs a DA and council considers whether the building contributes to the area's character. Approval to demolish a contributory building is not assured.
Other constraints
Depending on the property and the proposal, other matters can affect the pathway or conditions — for example certain environmental, coastal, flood or bushfire considerations. The planning certificate and a certifier are the right sources.
The proposal itself
Anything that does not fit the codes.
How to check your property
- Get the planning certificate from council.
- Check the LEP maps for heritage items and conservation areas, via council or the NSW Planning Portal.
- Ask a certifier or town planner to confirm the pathway for your specific proposal.
- Check the tree controls in council's DCP.
Do this before buying a property intending to knock it down.
Trees are separate but connected
Council tree controls usually sit in the DCP. A tree may be:
- Approved for removal as part of the development.
- Subject to a separate permit.
- Required to be retained and protected.
Removing a tree without the right approval can bring significant penalties, and on some blocks tree retention changes the design.
Conditions you will live with
Both pathways attach conditions. For demolition these commonly cover:
- Neighbour notification before work.
- Hours of work.
- Dust, noise, erosion and sediment control.
- Asbestos survey, licensed removal and clearance.
- Waste management and records.
- Dilapidation reports.
- Tree protection.
- Use of the footpath or road.
A demolition contractor's job is to follow those conditions exactly.
Who does what
| Task | Who |
|---|---|
| Choosing the pathway | Certifier or council, based on the property |
| Preparing the application | Owner, builder, designer or planner |
| Issuing a CDC | Accredited certifier (or council) |
| Determining a DA | Council |
| Supplying demolition details | Demolition contractor |
| Complying with conditions | Everyone on site |
Nobody — including the demolition contractor — can guarantee an approval outcome.

Questions people ask before they commit
What is the quickest way to get demolition approved in Sydney?
Where the property qualifies, a complying development certificate from an accredited certifier is usually the quicker route, because it is assessed against set standards rather than on its merits. Whether a property qualifies depends on its zoning, heritage status and other constraints.
Where can I find out if my property is heritage-listed?
The planning certificate issued by council for the property sets out many of the planning controls that apply, including heritage listings and conservation areas. Council's local environmental plan maps and the NSW Planning Portal are also useful starting points.
Can a certifier approve demolition in a heritage conservation area?
Generally complying development is restricted in heritage conservation areas and not available for heritage items, so demolition there commonly needs a development application to council. The detail depends on the controls that apply to the specific property.
Do I need approval to demolish a shed?
Some small outbuildings can be demolished as exempt development if they meet specific conditions. Larger structures, those in heritage areas, or those containing asbestos may need more. Check the conditions for the specific structure rather than assuming.
Can neighbours stop a demolition?
For a development application, neighbours can make submissions that council considers. They cannot veto it, but objections can affect conditions and timing. Complying development does not involve the same merit-based submission process, although notification requirements still apply.
