The Ultimate Guide to Council Demolition Approval in Sydney

Demolishing an old structure to build your dream home or a new duplex is an exciting step, but navigating Sydney's regulatory framework can be challenging. Whether you need a local council Development Application (DA) or a Complying Development Certificate (CDC) from a private certifier, understanding the process keeps your project on timeline and budget.

1. Complying Development Certificate (CDC) vs. Development Application (DA)

In NSW, you have two primary pathways for demolition approval. A Complying Development Certificate (CDC) is typically the fastest option, often approved within weeks rather than months. To qualify for a CDC, your demolition project must comply with the State Environmental Planning Policy (SEPP). A traditional Development Application (DA) is required if your property lies within a heritage conservation zone, is affected by specific ecological overlays, or does not meet standard SEPP criteria.

2. SafeWork NSW Asbestos Notification & Licences

Many older homes in Sydney contain legacy asbestos building materials, particularly fibro sheeting under eaves, in wet areas, or behind wall cavities. Demolition contractors must hold a Class A or Class B asbestos removal licence. Any removal of more than 10 square metres of non-friable asbestos must be officially notified to SafeWork NSW at least 5 days prior to work commencing. On completion, an independent, certified assessor must issue a clearance certificate before structural machinery can touch the site.

3. Services Disconnection & Utility Capping

You cannot legally or safely knock down a structure with active utilities. Standard council conditions require water, sewer, gas, electricity, and telecommunications to be disconnected at the mains supply point. The property owner must coordinate with energy and gas providers to remove meters and perform a 'truck roll' disconnection. Once street service lines are disconnected, licensed plumbers and electricians cap the entry pipes and cables at the property boundary to ensure no damage occurs to local grids.

4. Asset Protection Permits

Before any heavy plant machinery rolls onto your property, you must obtain an Asset Protection Permit from your local council (e.g. Inner West, Canterbury-Bankstown, or Randwick Council). This permit holds the builder or owner liable for any damage to public assets, including footpaths, road kerbs, nature strips, and drainage grates. Demolition contractors lay heavy rubber crossing pads or steel plates over public footpaths to distribute the weight of 20-tonne excavators and tippers, preventing costly repair fines.
