What’s the easiest way to check if my bathroom is compliant

23 April 2026

The easiest way to check whether your bathroom is compliant in Sydney is to look at a combination of documentation, visible workmanship standards, and whether licensed professionals were used during the renovation. Compliance isn’t just about how the bathroom looks—it’s about whether it meets Australian building, plumbing, waterproofing, and safety regulations.

If you’re unsure, you can follow a simple, practical checklist that homeowners commonly use before selling, renovating further, or making an insurance claim.


1. Check for Compliance Certificates

The most reliable starting point is paperwork. A compliant bathroom renovation should include:

  • Plumbing compliance certificates issued under Certificate of Compliance for Plumbing Work

  • Waterproofing documentation confirming adherence to AS 3740 Waterproofing of domestic wet areas

  • Electrical safety certificates (if any electrical work was done)

If these documents are missing, it doesn’t automatically mean your bathroom is non-compliant—but it does mean you should investigate further.


2. Confirm Licensed Trades Were Used

In NSW, all plumbing, electrical, and waterproofing work must be completed by licensed professionals. You can verify licences through NSW Fair Trading registers.

A compliant bathroom renovation should clearly show:

  • Licensed plumber details

  • Qualified electrician records

  • Certified waterproofer or builder involvement

If unlicensed trades were used, compliance risks increase significantly.


3. Look at Waterproofing and Drainage Quality

Waterproofing is one of the most important compliance areas. Signs of proper compliance include:

  • No signs of water leaks or damp patches

  • Properly sealed corners and junctions

  • Shower area fully contained with no overflow risk

Poor waterproofing is a common cause of non-compliance in older or DIY renovations.


4. Review Approval History (If Applicable)

Depending on the scope of your renovation, you may need to check whether formal approvals were required, such as:

  • Complying Development Certificate

  • Development Application

  • Strata by-law approval (for apartments)

If your bathroom layout was changed significantly and no approvals exist, it may indicate compliance issues.


5. Compare Against Basic Building Standards

All bathrooms must comply with the National Construction Code, which includes:

  • Proper ventilation

  • Safe electrical placement

  • Adequate drainage fall

  • Slip-resistant flooring in wet areas

Even without formal documents, visible design and safety features can give you clues about compliance.


Final and Easiest Method

From experience, the simplest and most reliable way to confirm compliance is to have a licensed builder or certifier perform a quick inspection. They can immediately identify whether the bathroom meets current NSW standards or if there are hidden risks.
