Planning a renovation, extension or commercial refit often starts with one big question: can you begin demolition straight away, or do you need council approval first?
For partial demolition in Sydney, the answer depends on the scope of work, the property type and whether structural elements are involved. Some minor works may be simple, while other demolition projects may need formal approval before anything can begin.
At WasteWise Services, we help homeowners, builders and commercial clients plan partial demolition safely and correctly. Before work starts, it is important to understand whether approval, certification or additional checks are required.
What Is Partial Demolition?
Partial demolition involves removing selected parts of a building while keeping the remaining structure intact.
This may include wall removals, bathroom demolition, internal strip outs, removal of non-load bearing sections, or selected structural demolition as part of a renovation or fit out.
Unlike full demolition, partial demolition requires careful planning. The goal is to safely remove what is no longer needed while protecting the building structure and maintaining structural integrity.
When Might Council Approval Be Required?
Council approval may be required when demolition affects the structure, external appearance or approved use of a building.
For example, approval may be needed if the work involves removing load-bearing walls, altering the building footprint, modifying a heritage property, or carrying out works that form part of a larger renovation or extension.
In NSW, some demolition can be assessed as complying with development if it meets the relevant standards under the Codes SEPP. The NSW Planning Portal explains that the Demolition Code can allow demolition of certain dwellings, industrial buildings and associated structures as complying with development, provided the standards are met.
What About Minor Internal Demolition?
Not every internal demolition project requires the same level of approval.
Minor internal works may be treated differently from structural demolition, especially if they do not affect load-bearing elements, fire safety systems, heritage features or external walls.
However, it is always worth checking before work begins. Removing the wrong section without approval or proper assessment can create delays, safety risks and compliance issues.
WasteWise Services can help assess the demolition scope and identify when further advice from a certifier, engineer or council may be needed.
Heritage Properties and Strata Buildings
Partial demolition in Sydney can become more complex if the property is heritage-listed, located in a conservation area or part of a strata scheme.
Heritage properties may have stricter controls around what can be removed or altered. Strata buildings may require approval from the owners corporation before internal demolition or strip out work begins.
This is especially important for apartment renovations, commercial suites and older buildings where structural elements, shared services or asbestos containing material may be present.
Safety, Asbestos and Demolition Notifications
Approval is only one part of planning a demolition project. Safety requirements also need to be considered.
If asbestos is present, licensed asbestos removal may be required before demolition continues. SafeWork NSW states that licensed asbestos removal work must be notified 5 calendar days before starting.
Certain demolition works may also require notification to SafeWork NSW. SafeWork NSW states that licensed demolition work must be notified 5 calendar days before it begins.
WasteWise Services can coordinate partial demolition with asbestos removal where required, helping reduce risk before the main works proceed.
Why Planning Before Demolition Matters
Partial demolition should never be rushed.
A proper review helps confirm what can be removed, what must stay in place and whether approval is needed. It also helps protect structural integrity, avoid damage and keep the wider renovation or refit on track.
For commercial spaces, this planning can also involve lease agreement obligations, building management requirements and safe access arrangements.
The earlier you confirm these details, the less likely you are to face delays once work begins.
