How to manage renovation approvals in a strata building? (Bathroom | Building & Approvals)

Renovating a bathroom in a Sydney strata building can feel like juggling flaming hammers while walking a tightrope over Sydney Harbour. Between neighbours, strata committees, building managers, councils, and licensed trades, the approval process can seem overwhelming. But with the right approach, planning, and communication, you can navigate it smoothly and legally — without turning your renovation into a nightmare.

Here’s a practical, step-by-step guide for managing renovation approvals in strata buildings, specifically tailored to Sydney homeowners.

1. Understand strata rules and by-laws

The first step to smooth renovations in a strata building is knowing the rules. Every Sydney strata scheme has a set of by-laws — often covering:

• Renovation approvals

• Noise restrictions

• Waterproofing requirements

• Common property usage

• Waste disposal

• Access for trades

Key point: Even minor bathroom renovations can involve common property (for example, pipes, walls, or floor slabs), meaning the owners corporation may have final say. Ignorance is not bliss — it can result in formal complaints, fines, or even a stop-work order.

Tip for Sydney residents: Always request a copy of the current by-laws from the strata manager before submitting your application.

2. Determine if you need formal strata approval

Not all bathroom works need strata approval, but most do when they involve:

• Structural changes (removing or moving walls, cutting slabs)

• Altering plumbing connected to common property

• Waterproofing or tiling that could affect neighbouring units

• Installation of major fixtures like spa baths or new showers

If your work is cosmetic (repainting, replacing vanity, or similar), approval may not be required. Always check first — assuming you’re exempt can create major headaches if a neighbour lodges a complaint.

3. Prepare your renovation plan

Before contacting your strata committee, prepare a detailed renovation plan, including:

• Floor plans showing existing and proposed layouts

• Detailed plumbing and drainage diagrams

• Waterproofing specifications and membranes

• Proposed materials and finishes

• Project timeline, including noisy works and trades involved

Sydney strata committees appreciate well-prepared applications — it shows professionalism and reduces unnecessary back-and-forth.

4. Lodge a formal renovation application

Most strata buildings have a standard renovation request form, sometimes called a “Renovation Approval Form” or “Alteration Form.”

A typical application should include:

1. Owner details — name, unit number, contact info

2. Scope of works — explain exactly what is being renovated and why

3. Contractor details — include licensed trades for plumbing, electrical, and waterproofing

4. Supporting documents — plans, engineering certificates, waterproofing certificates

5. Timeline and working hours — clarify when noisy works will occur

Some Sydney buildings require council approval or Construction Certificates before strata will consider your application. Make sure you check first.

5. Communicate with your strata committee

Communication is key. Even if your application is technically compliant, poor communication can trigger complaints.

• Notify neighbours of renovation dates and expected disruptions

• Share key details like contractor names, contact numbers, and work hours

• Address concerns proactively before they escalate

Tip: In Sydney apartments, it’s common for neighbours to complain even about minor drilling. By preemptively informing them, you reduce the chance of formal disputes.

6. Follow building and council requirements

Strata approval does not replace council or building requirements. Depending on your bathroom renovation, you may need:

• Development Application (DA) approval

• Complying Development Certificate (CDC)

• Construction Certificate (CC)

Sydney councils, such as City of Sydney, Inner West, or Northern Beaches, often require certified waterproofing, licensed plumbing, and correct engineering details. Ensure all documentation is ready before lodgement.

7. Ensure all trades are licensed

In NSW, only licensed tradespeople can carry out plumbing, electrical, and waterproofing work.

• Ask for licences and ensure they are current

• Ensure waterproofers provide a Certificate of Compliance

• Licensed trades are usually required for Council inspections and strata approval

Using unlicensed trades can void your approval, delay your project, and create legal issues in case of leaks or damages.

8. Address strata conditions

Most strata committees will approve renovations with conditions. Common conditions in Sydney include:

• Noise restrictions (e.g., 8am–5pm weekdays)

• Protection of common areas (lift, hallways)

• Daily cleanup of dust and debris

• Waterproofing certification before tile installation

• Notification to neighbours of critical works

Tip: Keep a checklist of these conditions and ensure trades comply. Non-compliance is the fastest way to receive complaints or stop-work orders.

9. Track approvals online where possible

Some Sydney strata buildings integrate with online portals for approvals or council submissions. Even if your building doesn’t, maintaining digital copies of all submitted forms, emails, and certificates is essential.

This helps when:

• Follow-up queries arise

• Insurance or warranty claims are needed

• You sell the property — buyers and valuers will request evidence of proper approvals

10. Manage complaints proactively

Even if everything is compliant, complaints may arise:

• Respond quickly and politely

• Provide evidence that approvals are in place

• Show certification from licensed trades

• Engage the strata manager if complaints escalate

Sydney strata complaints are often triggered by noise, dust, or neighbour fear of water damage. Managing expectations upfront prevents unnecessary disputes.

11. Inspect and certify post-renovation work

Once the renovation is complete:

• Obtain final plumbing, waterproofing, and building compliance certificates

• Schedule any required critical stage inspections

• Lodge certificates with the strata office and, if necessary, council

Proper certification ensures your renovation is fully legal, protects your insurance, and avoids future disputes.

12. Learn and document for the future

Post-renovation, maintain records of:

• Strata approval forms

• Contractor licenses and certificates

• Compliance certificates (waterproofing, plumbing, CC/CDC)

• Emails and communications with neighbours and strata

This documentation is invaluable for resale, insurance claims, and avoiding penalties.

13. Common pitfalls Sydney homeowners face

1. Starting renovations without strata approval — leads to fines and disputes

2. Using unlicensed trades — invalidates approvals and insurance

3. Ignoring noise and working hours — triggers complaints fast

4. Failing to submit required compliance certificates — delays occupancy or final approvals

5. Poor communication — neighbours feel excluded and complain

Avoid these, and your bathroom renovation will be smooth, legal, and neighbour-friendly.
