Property and scope information
Record the site address, title details, structures to be removed or retained, adjoining conditions, access constraints and the intended post-demolition use. Make partial demolition boundaries explicit.

Demolishing a House in NSW: Approvals and Pre-Demolition Checklist
A practical guide to the decisions and documents to organise before residential demolition—from the approval pathway and asbestos controls to service disconnections, site access and lawful waste handling.
Confirm the pathway before booking demolition
House demolition is not simply an equipment and disposal exercise. The lawful pathway depends on the property, planning controls, heritage and environmental constraints, the proposed demolition scope and what is intended for the site afterwards.
The NSW Planning Portal explains that some demolition can proceed as complying development when every relevant standard is met. Other proposals require a development application or another approval pathway. Council or a registered certifier should confirm the route for the actual property before work is programmed.
Eight items to organise before demolition starts
Planning and approval pathway
Ask council or a registered certifier whether the work may satisfy the Demolition Code for complying development or needs a development application. Check heritage, vegetation, flood, bushfire and other site controls.
Surveys and site records
Gather available survey, service, drainage and hazardous-material information. Identify boundaries, easements, neighbouring structures and public assets that may affect access or protection measures.
Asbestos and hazardous materials
Have the structure assessed by an appropriately competent person. SafeWork NSW says asbestos should be identified and removed before demolition, with licensed removal used where the law requires it.
Utility disconnections
Arrange required electricity, gas, water, sewer and communications isolations with the relevant providers and licensed trades. Keep written evidence of completed disconnections for the demolition team.
Access and neighbour interfaces
Plan machinery access, temporary fencing, exclusion zones, public-domain protection and deliveries. Confirm the notification duties attached to the approval and communicate practical impacts early.
Waste and material destinations
Identify waste streams, transport arrangements and authorised receiving facilities. Separate asbestos and contaminated material from recyclable or reusable building materials and retain disposal records.
Completion and handover records
Agree what evidence will be supplied at completion, such as waste dockets, clearance documents, service records and confirmation of the site condition before the next construction stage.
A practical approval sequence
Do not assume that a neighbour’s approval pathway will apply to your property. Use the sequence below to identify the decision-maker and required evidence.
| Stage | Question to resolve | Useful evidence |
|---|---|---|
| Site check | What planning, heritage, environmental or title constraints apply? | Planning property information, title, survey, council advice and known site constraints. |
| Pathway decision | Can the demolition meet every complying-development standard, or is a DA required? | Defined demolition scope, building information, site plan and advice from council or a registered certifier. |
| Pre-start conditions | What notices, bonds, controls and documents must be in place before work? | Approval conditions, neighbour notices, utility records, asbestos information, waste plan and site controls. |
| Handover | What evidence is needed before the next stage starts? | Clearance and disposal records, photos, service confirmation and the agreed condition of the cleared site. |
Asbestos, services and site risk need separate proof
- Asbestos: do not rely on appearance alone. SafeWork NSW directs demolition duty holders to check the asbestos register or arrange competent inspection when a register is unavailable.
- Hazardous materials: identify other chemicals, contaminated materials and unsafe building elements before workers or machinery are exposed.
- Services: obtain disconnection or isolation evidence from the relevant providers and licensed trades rather than treating an inactive appliance as proof.
- Adjoining property: document structures, retaining elements, shared boundaries and access conditions that may need protection or monitoring.
- Site access: check overhead and underground constraints, road interfaces, temporary fencing, delivery timing and the safe operating area for plant.
Make the waste pathway visible in the quote
The NSW EPA identifies concrete, bricks, timber, plasterboard, asphalt, excavated soil, asbestos and contaminated soil among common construction and demolition waste streams. A useful demolition proposal should explain how major streams will be separated, transported and received.
Ask who selects the receiving facilities, who retains dockets and clearance documents, and how unexpected material will be handled. The cheapest headline allowance can become expensive when hazardous material, unsuitable soil or access restrictions are excluded or undefined.
Questions to make demolition quotes comparable
Scope
Which structures, slabs, footings, pools, tanks, pavements, vegetation and services are included? What must remain and how will it be protected?
Approvals and notices
Who is responsible for applications, conditions, neighbour notifications, public-domain controls and any council security requirement?
Hazardous materials
What inspection information is included, what is provisional, and how will licensed asbestos or contamination work be priced and documented if required?
Waste and handover
Which disposal, recycling, clearance, dockets, final levels and site-condition records will be supplied at completion?
Connect demolition planning to the next project stage
This article supports the approval and preparation questions around demolition. For service scope, visit SCE’s residential demolition scope review. If the cleared site will move into excavation, drainage or new external works, review earthworks, concreting and underground services.
When the scope is still being defined, send the site address, proposed works, available approval information, hazardous-material records and intended next stage through the SCE enquiry page.
House demolition in NSW FAQs
Does demolishing a house in NSW need a DA or CDC?
It depends on the property and proposed work. Some demolition may proceed as complying development when every relevant standard is met; other sites or scopes need a development application or another approval. Ask the local council or a registered certifier to confirm the pathway.
Can demolition start before approval for the replacement home?
Do not assume it can. Approval sequencing can affect knockdown-rebuild projects, and the NSW Planning Portal advises confirming the demolition and new-home pathways before work begins. Check the actual approvals and conditions with council or the certifier.
Who should disconnect utilities before demolition?
Disconnections and isolations should be arranged with the relevant utility providers and licensed trades. The demolition team should receive written evidence that required electricity, gas, water, sewer and communications services are safe for the agreed scope.
How should asbestos be checked before house demolition?
SafeWork NSW says the asbestos register should be checked before demolition or, if no register is available, a competent person should inspect the structure. Asbestos must be removed before demolition, with licensed removal used where required by law.
Do neighbours need to be notified?
Notification duties depend on the approval pathway, location and approval conditions. Complying development can include pre-approval and pre-construction notification requirements. Confirm the required recipients, notice period and format before programming work.
What demolition waste records should an owner retain?
Retain the records required by the approval and contract. These may include waste and recycling dockets, asbestos or contamination clearances, service-disconnection evidence and completion records showing the agreed condition of the site.
What information should I send when requesting a demolition review?
Provide the site address, structures to remove or retain, available survey and approval information, known asbestos or contamination records, service information, access constraints and what is planned after demolition. This helps identify missing inputs before scope and pricing are compared.
Need a clearer demolition scope before you seek pricing?
Share the site, proposed demolition boundaries, available approvals and the intended next stage. SCE can review the information and clarify an evidence-based next step without treating unverified assumptions as project facts.
