Demolition Permits Sydney NSW — What You Actually Need
Updated March 2026 — Direct Demolition Sydney
Every house demolition in New South Wales needs an approval — there's no legal "just knock it down" path. The two routes are a Complying Development Certificate (CDC) through a private certifier, or a Development Application (DA) through your local council. This guide explains which one you need, how long each takes, and what documents you'll need to have ready.
The Two Approval Paths
| Approval type | Typical timeline | Typical fee | Best for |
|---|---|---|---|
| CDC (private certifier) | 1–3 weeks | $1,200 – $2,800 | Standard demolitions meeting state standards |
| DA (local council) | 6–12+ weeks | $700 – $5,000+ | Heritage, conservation, larger commercial |
| Section 4.55 modification | 2–6 weeks | $500 – $2,000 | Modifying an existing DA |
| Exempt development | No formal approval | Nil | Small sheds, fences, minor structures only |
When You Can Use a CDC
Under the NSW State Environmental Planning Policy (Exempt and Complying Development Codes), most standard residential demolitions can be approved as Complying Development if they meet specific standards:
- The property is not heritage-listed or contributory.
- The property is not in a heritage conservation area (most councils).
- The land is not affected by flood, bushfire or environmental hazard overlays that exclude CDC.
- Setback, height and access requirements are met for the planned works.
- Asbestos removal will be carried out by a licensed contractor.
When You'll Need a DA
- The dwelling is a heritage item or contributory item.
- The property is in a heritage conservation area.
- The site has bushfire, flood or coastal overlays that exclude CDC pathways.
- Demolition is part of larger commercial or multi-dwelling redevelopment.
- Significant trees are involved that need separate council approval.

Documents You'll Need
- Demolition Work Plan — Sequence, plant, traffic management, dust and noise controls. We provide this for every job.
- Hazardous Materials / Asbestos Survey — Required for properties built before 1990 (and recommended for everything pre-2000).
- Service disconnection evidence — Letters or job numbers from gas, electricity, water, sewer and Telstra.
- Public liability insurance certificate — Demolition contractor's $20M minimum.
- Demolition contractor licence — NSW Demolition Licence number (Direct Demolition: AD214611).
- Asbestos contractor licence — Class B for bonded (we hold AD214613); Class A required for friable.
- Site plan — Existing structures, neighbours, trees, services.
- Waste management plan — Where the material will go and how much.
The Approval Process Step by Step
- Engage a private certifier (or lodge with council if DA required).
- Commission asbestos survey and obtain a report.
- Apply for service disconnections — start early, gas is the slowest.
- Provide all documentation to certifier/council.
- Certifier issues the CDC, or council determines the DA.
- SafeWork NSW notification (5 working days before commencement for asbestos work).
- Demolition commences.
Common Permit Mistakes
- Booking a demolition before approval is in hand. Certifiers can request changes; never lock in a date until the certificate is issued.
- Skipping the asbestos survey on a pre-1990 home. Almost guarantees questions back from the certifier.
- Forgetting Telstra. The pit and lead-in often need formal abolishment, not just a phone-line cancellation.
- Assuming exempt development applies to attached structures. Most attached additions don't qualify.
- Heritage assumption errors. Many Inner West and Eastern Suburbs streets are conservation areas even when individual houses aren't listed.

Frequently Asked Questions
Do I need a permit to demolish a house in NSW?
Yes. Every demolition in NSW requires either a Complying Development Certificate (CDC) issued by a private certifier, or development consent (a DA) issued by your local council. Heritage and conservation-area properties usually need a DA.
What's the difference between a CDC and a DA?
A CDC is a faster, standards-based approval issued by a private certifier — typically 1–3 weeks. A DA goes through council with public notification and assessment — typically 6–12+ weeks. CDCs only apply where the proposed work meets pre-set standards.
How long does a demolition CDC take in Sydney?
From application to certificate: 1–3 weeks for most jobs, assuming complete documentation and no objections. Asbestos reports, service disconnection evidence and structural reports speed things up.
How much does a demolition permit cost?
Private certifier CDC fees for demolition typically run $1,200–$2,800. Council DA fees vary by property value but start around $700 and can run several thousand for larger sites.
Do I need a permit to demolish a shed or garage?
Detached structures under certain size limits may be exempt development. Most attached garages and habitable outbuildings still need a CDC or DA. Always check with a certifier or council first.
Can my demolition contractor get the permit for me?
We can refer you to certifiers we work with regularly and help coordinate the asbestos report, structural advice and service disconnection evidence the certifier needs. The application itself is between you and the certifier or council.
