How to apply for strata approval for bathroom works

23 April 2026

If you’re planning a bathroom renovation in Sydney and your property is part of a strata scheme, obtaining strata approval is a critical first step. Bathroom works often involve plumbing, waterproofing, and structural elements—areas that fall under common property—so you cannot legally proceed without approval from the owners corporation.

Step 1: Understand the Type of Renovation

In NSW strata properties, bathroom renovations are typically classified as “major renovations” because they involve waterproofing and changes to plumbing. This means you’ll need formal approval under the Strata Schemes Management Act 2015.

Minor cosmetic updates (like replacing taps or fixtures without altering walls or pipes) may not require full approval, but it’s always safest to confirm with your strata manager first.

Step 2: Prepare Detailed Documentation

To apply for strata approval, you’ll need to submit a clear and professional renovation proposal. This usually includes:

  • A detailed scope of works

  • Bathroom layout plans (existing and proposed)

  • Waterproofing details and materials

  • Licensed contractor information (builder, plumber, waterproofer)

  • Proof of insurance (public liability and workers compensation)

  • Estimated timeline for the works

The more complete your submission, the faster and smoother the approval process will be.

Step 3: Submit a By-Law Application

For major renovations, you’ll need to request a by-law to be added or amended. This gives you legal permission to carry out the works and often transfers responsibility for future maintenance of the renovated bathroom to you.

Your application is typically submitted to the strata committee or strata manager, who will then arrange for it to be voted on at a general meeting.

Step 4: Attend the Strata Meeting

Your proposal will be reviewed and voted on by the owners corporation. Approval usually requires a special resolution (at least 75% of votes in favour).

Timeframes vary, but most approvals take:

  • 2 to 6 weeks, depending on meeting schedules and how prepared your documents are

Step 5: Comply With Conditions

Once approved, you’ll likely need to follow specific conditions, such as:

  • Working within approved hours

  • Protecting common areas (lifts, hallways)

  • Notifying neighbours before works begin

  • Providing a completion certificate, including waterproofing compliance

Why Professional Help Matters

From experience, many delays in strata approval come from incomplete or unclear submissions. Working with a Sydney-based bathroom renovation specialist ensures:

  • Your documentation meets strata requirements

  • All trades are properly licensed and insured

  • The process is handled efficiently with minimal back-and-forth

Final Tip

Strata approval isn’t just a formality—it protects both you and the building. Getting it right from the start avoids disputes, delays, and costly rework.
