1. Overview: Do You Usually Need Approval?

Here’s the simple version:
Most standard bathroom renovations in Wollongong do NOT require council approval.

If you’re:

  • Keeping the same layout, OR
  • Upgrading fixtures, tiles, and finishes, OR
  • Replacing old plumbing with new plumbing in the same position

…you’re usually in the clear. These fall under what NSW calls
“exempt development” — meaning no DA, no CDC, no council paperwork.

But — and this is where most people get confused — there are definitely situations where approval is required.
It depends on structural work, waterproofing changes, drainage modifications, and whether your home is heritage-listed.

2. When You Don’t Need Council Approval

The majority of bathroom renovations in Wollongong fall into this category. You generally do not need
approval if your renovation is:

2.1 A like-for-like update

  • New tiles
  • New vanity
  • Replacing the toilet
  • Installing a new shower screen
  • Upgrading lighting or ventilation

As long as everything stays in roughly the same position, there’s usually no approval required.

2.2 Internal, non-structural work

NSW planning rules consider most internal cosmetic work to be “exempt development”. That means you can go ahead
without notifying council.

2.3 Waterproofing done by a licensed tradesperson

Waterproofing does NOT require council approval, but it must be carried out by a licensed professional
who provides a certificate — this is essential for compliance and insurance.

2.4 No changes to drainage or external walls

As long as you’re not altering major plumbing infrastructure outside the bathroom or cutting into structural or external
walls, you’re usually fine.

3. When You Do Need Council Approval

While many bathroom renovations are exempt, approval is required when you make bigger changes. You may need
either a Development Application (DA) or a Complying Development Certificate (CDC)
in the following cases:

3.1 Significant structural changes

  • Removing or altering load-bearing walls
  • Widening windows or doors
  • Changing the building footprint

3.2 Major plumbing or drainage relocation

If your renovation moves key plumbing lines into new positions — especially if drainage is involved — you may
require approval.

3.3 Converting another room into a bathroom

Turning a bedroom, laundry, or study into a new bathroom often requires approval because you’re changing the
property’s layout and plumbing infrastructure.

3.4 Heritage-listed properties

Parts of Wollongong, especially older suburbs, have homes with heritage protections. In these cases,
any renovation may require approval — even interior work.

3.5 Larger extensions involving a bathroom

If the bathroom is part of a bigger home extension or second-storey addition, the entire project requires council
approval — including the bathroom.

4. What is a Complying Development Certificate (CDC)?

A CDC is a fast-tracked version of council approval. Instead of waiting months for a DA,
a CDC can be approved by a private certifier in as little as 10 days.

You might need a CDC if your renovation involves:

  • Moving plumbing to a new location
  • Internal changes that affect structure
  • Compliance with specific building codes

It’s a popular option because it speeds up approvals compared to the DA process.

5. Development Application (DA): When Is It Required?

A DA is the traditional, more detailed approval process through Wollongong City Council.
You’ll generally need a DA if:

  • Your home is heritage-listed
  • You’re making significant structural changes
  • The work exceeds the limits of exempt or complying development
  • You’re adding an entirely new bathroom where plumbing doesn’t currently exist

A DA takes longer than a CDC — sometimes several months — but is required for complex renovations.

6. Special Conditions for Strata Apartments & Townhouses

If you’re in an apartment or townhouse under strata title, there’s an extra step:

You must get approval from your Owners Corporation.

Even if the renovation is exempt development, strata rules override council rules for internal changes.
Expect the following:

  • Providing drawings or plans
  • Showing waterproofing certificates
  • Proving your trades are licensed and insured
  • Formal approval via a special or ordinary motion

Strata approval can take anywhere from 2 to 8 weeks depending on meeting schedules.

7. Real-Life Scenarios: Approval or No Approval?

Scenario 1: Replacing old fixtures, tiles and vanity

No council approval needed.

Scenario 2: Moving the shower and toilet to different positions

Possibly — a CDC may be required.

Scenario 3: Turning a laundry into a second bathroom

Yes, likely requires CDC or DA.

Scenario 4: Bathroom renovation in a heritage home in Wollongong

Yes, DA required.

Scenario 5: Renovating a bathroom in a strata apartment

Strata approval required.

Scenario 6: Adding a skylight or modifying a window

Often requires approval depending on structural impact.

8. Risks of Renovating Without Approval

It might be tempting to skip the red tape — but the risks are real and can be expensive.

  • Fines from council for unauthorised work
  • Insurance complications if something goes wrong
  • Problems when selling — missing approval documents can turn buyers away
  • Forced demolition of non-approved work in serious cases

It’s always cheaper to get the right approvals than to fix problems caused by skipping them.

9. Tips to Stay Compliant and Avoid Delays

Tip 1: Work with licensed, experienced renovators

They’ll know exactly when approvals are needed and will guide you step by step.

Tip 2: Finalise your design early

Changing your mind later can affect compliance and trigger extra approvals.

Tip 3: Check your property’s zoning and heritage status

This is easy to do and saves a lot of headaches down the road.

Tip 4: Get strata approval early if you’re in a unit

Strata can be slow — start the process ASAP.

Tip 5: Keep copies of all certificates and documentation

Especially waterproofing certificates, plumbing approvals, and compliance documents.
