Strata Renovation Rules NSW: What Sydney Apartment Owners Need to Know Before Starting Interior Demolition
Renovating an apartment in Sydney is not the same as renovating a freestanding home. The building is shared. The structure is shared. And the rules that govern what you can do, when you can do it, and how you must do it are set by the owners corporation, not just by council.
Most apartment owners find this out the hard way. A bathroom demolition gets booked. The crew arrives. And someone from building management is at the door explaining that no approval was obtained and work cannot start. That is an expensive morning.
What follows covers what the approval process actually looks like, what your contractor needs to provide, and what the common restrictions are so nothing gets in the way of your renovation programme. For anyone planning their first interior demolition, our residential interior demolition service page covers the full scope across apartment and house projects.
Key Takeaways
- ✓
Most strata schemes require owners corporation approval before any interior renovation begins, regardless of council requirements - ✓

Your contractor must provide SWMS, licence copy, and current public liability insurance before the OC will approve works - ✓
Noise hours, lift booking, waste routes, and common area protection are all governed by strata by-laws - ✓
Proceeding without OC approval is a by-law breach that can result in NCAT orders, remediation costs, and programme delays - ✓
Heritage strata buildings require council consent on top of OC approval before interior elements can be removed
Why Interior Demolition in a Strata Building Is Different
Unlike a freestanding home, interior demolition in a strata building usually requires approval from the owners corporation, even when council approval is not required.
Strata changes that entirely. Under the Strata Schemes Management Act 2015 (NSW), the owners corporation is responsible for the common property of the building. This includes structural elements, waterproofing systems, shared services, lift shafts, lobbies, and corridors. Interior demolition inside an individual lot can affect all of these, even when the work stays within the unit boundaries.
A bathroom tile removal that damages the waterproofing membrane affects the lot below. Waste being carried through the lobby damages the common area carpet. A skip in the car park blocks emergency access. These are not hypothetical concerns. They are the real reasons strata schemes require works approval before renovation begins.
The approval and compliance framework for interior demolition in NSW is covered more broadly in our article on interior demolition approvals in NSW. What follows covers the strata-specific layer on top of that framework.
The Owners Corporation Approval Process
The OC approval process varies between strata schemes. But the general sequence is consistent across most buildings in Sydney.
| Step | Typical Time |
|---|---|
| Obtain and review strata by-laws | 1 to 2 days |
| Prepare works notice and contractor documents | 2 to 5 days |
| OC committee review | 2 to 4 weeks |
| Book service lift and lodge renovation bond | 2 to 7 days |
| Demolition commences on site | After written approval |
Allow at least two to four weeks for OC approval before committing to a builder start date. Booking trades and a demolition crew before approval is in hand creates programme conflicts when the OC takes longer than expected or requests additional documentation.
Common Strata By-Law Restrictions for Interior Works
These are the conditions that appear most frequently in OC approvals for interior demolition across Sydney apartment buildings.
| Restriction | Usually Required |
|---|---|
| OC approval before works begin | ✓ Yes |
| Approved noise hours | ✓ Yes |
| Lift booking and protection | ✓ Yes |
| Common area and corridor protection | ✓ Yes |
| Renovation bond | Often |
| Public liability insurance certificate | ✓ Yes |
| Safe Work Method Statement (SWMS) | ✓ Yes |
Noise hours
Most strata schemes in Sydney restrict noisy works to Monday to Friday, 8 am to 5 pm. Some allow Saturday works between 8 am and 1 pm. Sunday works are almost never permitted. Power tools, angle grinders, and jackhammers all fall under noise restrictions. Works outside approved hours are a by-law breach, even with approval in hand. Confirm the exact hours in the OC approval before scheduling the crew.
Lift booking and protection
Buildings with lift access require the service lift to be booked in advance for waste removal and tool movement. Most buildings require protective pads on lift walls and floor protection in the lift cab during works. The demolition crew cannot use the passenger lift for waste movement. Lift booking slots fill quickly in busy buildings. Book as soon as OC approval is received.
Common area protection
Lobby floors, corridor carpets, and the building entry must be protected during works. Heavy-duty ram board or construction film on hard floors and masonite over carpet in corridors from the unit door to the lift is the standard. Any damage to common areas during works is the owner’s financial responsibility, not the strata’s. Document the condition of common areas before works begin and after completion.
Waste removal routes
The OC will specify which route waste must travel from the unit to the skip. In most buildings this means a designated service corridor or goods entry, not through the main lobby. Skip placement is often restricted to a designated area of the car park or requires a street permit. Waste removal timing may be restricted to specific hours or days to avoid peak resident traffic times.
Renovation bond
Many strata schemes require a renovation bond before works begin, typically between $500 and $2,000, held by the OC against potential damage to common property. The bond is returned after works are complete and a building manager inspection confirms common areas are undamaged. Factor this into the project budget. It is not a fee. It is a security deposit.
Contractor credential requirements
Most strata schemes require the demolition contractor to hold current public liability insurance (minimum $10 million, most buildings require $20 million), a SafeWork NSW demolition licence, a site-specific SWMS, and workers compensation insurance. The strata manager will not forward the works notice for OC review without these documents attached.
Documentation Your Contractor Must Provide for OC Submission
A professional demolition contractor working in strata buildings provides these without being asked. If you have to chase any of them, that is worth noting before committing to a booking.
Required Documents
- ✓ Safe Work Method Statement specific to the scope and building
- ✓ Current public liability insurance certificate of currency ($20 million minimum)
- ✓ SafeWork NSW demolition licence copy
- ✓ Workers compensation insurance certificate
- ✓ Method statement for dust and noise management during works
Sometimes Also Required
- ➞ Structural engineer’s letter for load-bearing wall removal
- ➞ Asbestos clearance certificate for pre-1990 buildings
- ➞ Waterproofing protection plan for wet area works
- ➞ Contractor’s subcontractor list (plumber, electrician) with their insurances

What Happens If You Proceed Without OC Approval
Proceeding with interior demolition in a strata building without OC approval is a by-law breach under the Strata Schemes Management Act 2015. The consequences are real and the financial exposure can exceed the cost of the renovation itself.
- ✗
Stop-work order. The OC or strata manager can issue a notice requiring all works to cease immediately. The crew leaves. Costs continue. - ✗
NCAT application. The OC can apply to the NSW Civil and Administrative Tribunal for orders requiring the owner to rectify the breach, which can include restoring the unit to its pre-demolition state. - ✗
Financial liability for common area damage. Without approved documentation, proving a pre-existing condition is nearly impossible. Any damage to common areas is the owner’s liability. - ✗
Impact on sale. Unapproved renovation works that affect strata common property or structure can create disclosure obligations and affect settlement if the property is sold while the breach is unresolved. - ✗
Penalty notices. Fair Trading NSW can issue penalty notices under the Strata Schemes Management Act for certain by-law breaches.
The OC approval process takes two to four weeks. The consequences of skipping it can take months to resolve and cost significantly more than the renovation itself. There is no practical argument for proceeding without it.
Heritage Strata Buildings: The Additional Layer
Sydney has a significant number of heritage-listed apartment buildings, particularly in inner suburbs like Potts Point, Paddington, Surry Hills, Newtown, and Balmain. If the building is heritage-listed or in a heritage conservation area, interior demolition requires council consent on top of OC approval.
Heritage listing at the building level does not necessarily mean every internal element is protected. But it does mean council assesses whether the proposed works affect the heritage significance of the building, including internal fabric where the listing covers it.
The process involves a Development Application to council, a Statement of Heritage Impact prepared by a heritage consultant, and council review. The OC cannot approve the works until council consent is granted. Both approvals must be in hand before demolition begins.
Check your section 10.7 planning certificate to confirm whether the building or area carries a heritage overlay before booking any trades or engaging a strata manager on the works notice process.
How It Works in Practice: Apartment Bathroom Demolition
Here is how a standard apartment bathroom interior demolition runs from start to handover in a typical Sydney strata building.
How Strata Affects Interior Demolition Costs
Interior demolition in a strata building costs more than the equivalent scope in a freestanding home. Not dramatically. But the additional time, planning, and compliance requirements add up.
The main cost additions in a strata environment: restricted working hours reduce daily output which adds to the programme; lift access for waste adds time to each waste run compared to a driveway skip; corridor protection, common area inspection, and administration of the OC submission add overhead; and asbestos assessments in older buildings (common in Sydney’s 1960s to 1980s strata stock) add cost before the demolition itself begins.
