If you're planning a bathroom renovation in Sydney, it’s important to understand whether you need council approval before work begins. The answer depends on the extent of the renovation, the type of property, and whether structural changes are involved. Getting this part right from the beginning can save you time, money and legal headaches down the line.
When council approval is not required
For most standard bathroom updates that don’t involve major structural changes or moving services, formal approval from council is not needed. These are generally considered exempt development under NSW planning laws.
Works that generally do NOT require council approval:
- Replacing tiles, tapware or fittings
- Installing a new toilet, shower or vanity in the same location
- Painting and cosmetic updates
- Waterproofing or re-sealing
These types of changes are considered low-impact, provided the work complies with the Building Code of Australia and relevant Australian Standards. However, using licensed professionals and maintaining good documentation is still essential.
When approval is required: DA or CDC
If your renovation includes structural changes or impacts external elements of your property, you’ll likely need some form of approval. In New South Wales, this will either be a Development Application (DA) or a Complying Development Certificate (CDC).
You may need council approval for:
- Moving internal walls
- Adding windows or skylights
- Altering plumbing locations (especially slab penetrations)
- Extending or reconfiguring the floor plan
- Converting a bedroom or laundry into a bathroom
The CDC process is a fast-tracked approval path for straightforward works that meet the strict development standards. A DA, on the other hand, is a more formal process submitted through your local council and may take longer, especially in heritage zones or flood-prone areas.
Your builder or designer can often help determine which path is suitable. At Balmoral Bathrooms, we assess each project and help clients secure the appropriate approvals when required.
Living in a strata building? Read this first
If your home is part of a strata scheme—such as an apartment or townhouse—you’ll also need approval from your owners’ corporation before commencing work. This is in addition to any council permissions that may be required.
Most strata schemes will require:
- A formal renovation application
- A by-law or special resolution (for major works)
- Details of waterproofing and insurance
- Trade licences and work schedules
It’s common for strata properties to have shared walls, floors or plumbing, which are considered common property. This means even minor bathroom updates can affect other units. Starting work without approval could result in legal disputes or being asked to restore everything at your own cost.
What about heritage-listed properties?
If your home is heritage-listed or located in a conservation area, any change—no matter how small—may require council approval. This includes internal changes such as altering layouts or materials. It’s essential to check your property’s zoning status before beginning any works.
We recommend contacting your local council or checking the NSW Planning Portal to confirm whether your property falls into this category.
Common pitfalls to avoid
Renovating without the right approvals can result in:
- Stop-work orders from council
- Penalty notices or fines
- Delays in future property sales (non-compliant work must be disclosed)
- Insurance issues if defects occur
It’s always cheaper and easier to get approval upfront than to deal with remediation later.
What’s the safest way to proceed?
Here’s a simple checklist:
- Scope your renovation. Will it include layout changes, plumbing, or structural work?
- Check zoning. Use the NSW Planning Portal or ask your builder.
- Confirm with your strata. If applicable, prepare the right documents.
- Speak with your builder. At Balmoral Bathrooms, we handle these checks as part of our quoting process.
