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.
