Renovating an apartment or unit in Sydney can be exciting, but strata approval is one of the biggest hurdles owners face before work begins. If you start renovations without the right approval, you may be ordered to stop work, reverse completed changes, repair common property, deal with neighbour complaints or face costly disputes through the owners corporation.

For anyone planning unit renovations in Sydney , understanding the approval process early can save time, stress and money. The good news is that strata approval is manageable when you know what type of renovation you are doing, what documents are required and who needs to approve the work.

In a strata building, you own your lot, but many parts of the building are shared common property. This can include external walls, structural elements, waterproofing membranes, pipes, ceilings, floors, windows, balconies and service infrastructure.

That means even renovations inside your apartment may affect areas you do not exclusively own. A bathroom renovation , flooring replacement or kitchen upgrade may seem straightforward, but it can still trigger strata requirements if it affects plumbing, waterproofing, noise transfer or common property.

Getting approval protects you by confirming the work is properly documented before construction begins.

Before speaking with builders or ordering materials, request a copy of your strata scheme’s by-laws. By-laws often outline:

Renovation approval requirements
Permitted work hours
Noise rules
Flooring and acoustic requirements
Lift protection requirements
Waste removal rules
Contractor insurance requirements
Common property restrictions

Every building is different. A renovation that is simple in one Sydney apartment building may require more documentation in another.

NSW strata renovation approvals generally fall into three broad categories.

Cosmetic work is usually low-impact and does not affect common property, structure or waterproofing. Examples may include:

Painting internal walls
Installing curtains or blinds
Filling small wall holes
Replacing removable fixtures
Installing picture hooks

Cosmetic work often does not require formal approval, but owners should still check their scheme’s by-laws and notify strata where required.

Minor renovations usually require approval from the owners corporation or strata committee, depending on the scheme’s by-laws. Examples may include:

Kitchen renovations
Replacing flooring
Renovating internal cabinetry
Installing or replacing hard flooring
Some non-structural internal changes
Bathroom upgrades that do not affect waterproofing

Minor renovations usually need a formal application with supporting documentation before work starts.

Major renovations generally require more formal approval, often by special resolution at a general meeting. Examples may include:

Structural changes
Work affecting waterproofing
Changes to common property
External appearance changes
Moving plumbing services
Altering load-bearing walls
Bathroom renovations involving waterproofing membranes

Major works may also require a renovation by-law, legal documentation and additional technical reports.

Strata approval and council approval are not the same thing. Some renovations may require only strata approval, while others may also need council approval, a complying development certificate or certification from relevant professionals.

This depends on the scope of work. Structural changes, changes to fire safety systems, changes to building services or certain layout alterations may require further approval. A professional renovation contractor experienced in Sydney apartment projects can help identify approval requirements early.

A strong application is one of the best ways to avoid delays. Your strata renovation application may need:

Scope of works
Floor plans or drawings
Product specifications
Waterproofing details
Acoustic reports for flooring
Engineering reports if structural work is involved
Contractor licence details
Public liability insurance certificates
Work schedule
Waste management plan
Access and lift protection plan
Proposed work hours

The more complete your application is, the easier it is for the strata committee or owners corporation to review.

Once your documents are ready, submit the application to the strata manager, strata committee or owners corporation, depending on your building’s process. Your application should clearly explain:

What work is being done
Where it will occur
How long it will take
Which contractors are involved
How common property will be protected
How noise, dust and waste will be managed

For apartment renovations in Sydney, clarity is critical because neighbouring residents, shared access areas and building services are often affected.

Approval timeframes vary widely between buildings. Some minor renovations may be approved relatively quickly if the strata committee has authority. Larger or more complex renovations may need to be tabled at a general meeting, which can take longer. Common causes of delays include:

Missing documents
Unclear scope of works
No contractor insurance details
No acoustic report for hard flooring
Waterproofing concerns
Work affecting common property
Committee meeting schedules

Starting early helps avoid delays to your renovation start date.

Strata approval often comes with conditions. These may include:

Work only during approved hours
Lift and common area protection
Licensed and insured contractors only
Noisy works limited to certain times
Waterproofing certification
Acoustic certification
Rubbish removal requirements
Final inspection or completion documents

These conditions are not optional. Failing to follow them may cause disputes or delays.

Do not rely on verbal approval from a neighbour, committee member or building manager. Before starting work, make sure you have written approval and a clear record of any conditions attached. This protects you if questions arise later.

During the renovation, keep copies of:

Strata approval
Contractor licences
Insurance certificates
Receipts and warranties
Waterproofing certificates
Compliance certificates
Acoustic documents
Completion photos

These records may be useful if you sell the apartment later or if strata requests proof of compliance.

Many approval problems happen because owners underestimate what counts as strata-related work. Common mistakes include:

Replacing carpet with timber or hybrid flooring without acoustic approval
Starting bathroom renovations without waterproofing approval
Assuming internal walls are automatically non-structural
Changing plumbing locations without checking common property impact
Booking trades before approval is granted
Submitting incomplete applications
Ignoring building work-hour restrictions

Avoiding these mistakes can save significant time and cost.

Strata approval can feel overwhelming, especially if this is your first apartment renovation. Between by-laws, forms, drawings, trade licences, insurance documents and committee questions, the paperwork can quickly become stressful.
