Do You Need Council Approval to Renovate a Bathroom in NSW?

Renovating your bathroom in NSW can breathe new life into your home, boost property value, and improve day-to-day functionality. But before you get started, many Sydney homeowners ask the same important question: Do I need council approval to renovate my bathroom? The answer depends on a few key factors, including the scope of work and whether any structural or plumbing changes are involved.

When You Don’t Need Council Approval

In most cases, minor internal bathroom renovations do not require council approval. This includes work such as:

  • Replacing tiles or waterproofing

  • Installing a new vanity, shower screen, or toilet in the same position

  • Updating fixtures and finishes without moving plumbing

  • Cosmetic upgrades like painting, lighting, and fittings

As long as the renovation doesn’t alter the structure of the building or move plumbing/drainage, it typically falls under exempt development. That means you’re free to proceed without council approval — provided the work complies with the NSW Building Code and Australian Standards.

When Council Approval Is Required

Council approval, a Complying Development Certificate (CDC), or a Development Application (DA) may be necessary if your bathroom renovation includes:

  • Working in a heritage-listed property

  • Adding a bathroom as part of a home extension or new build

In these situations, you’ll likely need to engage an architect or certifier to submit plans for approval before any work begins.

What About Waterproofing & Plumbing?

Even when council approval isn’t required, bathroom renovations must still comply with NSW building regulations, including:

  • Waterproofing must be done by a licensed professional with a waterproofing certificate

  • Plumbing work must be completed by a licensed plumber and lodged with Sydney Water where applicable

At Fresher Bathrooms Sydney, we ensure every renovation is fully compliant with state and local regulations, giving you confidence that your bathroom is built to last.

Strata & Apartment Living Considerations

If you live in a strata property (like a unit or townhouse), you’ll need to:

  • Get approval from the owners corporation

  • Submit plans showing what changes you’re making

  • Comply with strata by-laws and renovation rules

We recommend checking with your strata manager early in the process to avoid delays.

Final Tip: Always Check Before You Start

Regulations can vary slightly between councils, especially for heritage homes or homes in flood-prone areas. It’s always smart to:

  • Speak with your local council or private certifier

  • Consult a renovation expert like our team at Fresher Bathrooms

  • Ensure all trades are licensed and insured
