The short answer
- Planning approval and building approval are separate. Planning approval comes from Brisbane City Council and is mostly about what the house does to the street. Building approval comes from a building certifier and is about whether the work is structurally and legally sound.
- Renovations that only involve internal work are unlikely to need planning approval, in Brisbane City Council's own words — but they can still need building approval if anything structural changes.
- Brisbane City Council states you will need building approval before starting work on extensions, raising and renovations. Your certifier is the one who determines what your specific job needs.
- Moving a toilet, shower, basin or kitchen sink is notifiable plumbing work. Your licensed plumber must register it with the QBCC, and you should keep the record.
- Getting the right approvals in place before work starts is the home owner's responsibility, even when you have engaged a builder.
Almost every homeowner planning a renovation asks some version of this question, and almost every answer they find online is unhelpful, because it treats "council approval" as one thing. It is not. There are two separate approvals in Queensland, they come from two different places, and they are triggered by two different aspects of your project.
Get that distinction clear and the rest of it becomes straightforward.
Planning approval and building approval are not the same thing
Planning approval is a decision by Brisbane City Council under the city's planning scheme. It is concerned with land use and with the effect your project has on its surroundings: how close it sits to a boundary, how tall it is, what it does to the streetscape.
Building approval is a decision by a building certifier — usually a private one — under Queensland's building laws and the Building Code of Australia. It is concerned with whether the thing you are building is safe, structurally adequate, weatherproof and compliant.
A renovation can need planning approval and not building approval, building approval and not planning approval, both, or neither. They are assessed independently, so satisfying one tells you nothing about the other.
Planning approval: when Brisbane City Council gets involved
For most renovations, the deciding factor is whether the work is visible from outside and whether the house is old enough to sit in a character overlay.
Brisbane City Council's own guidance is direct on the common case:
If your renovations only involve internal works, you're unlikely to need planning approval.
That covers a large share of the work we do — bathrooms, kitchens, laundries, reworked internal layouts — as long as the building's external form is not changing.
Where it gets more involved is with older housing stock. Council states that some extensions and renovations to a house built during or before 1946 require planning approval. If your site sits in the Traditional building character overlay, Council's position is that you will generally need planning approval for external extensions, and that extensions and renovations to a pre-1947 house involving some demolition may need assessment against the Traditional building character (demolition) overlay code and the Traditional building character (design) overlay code.
The overlay is about the street, not about your taste. Council describes its purpose as maintaining the traditional, pre-1947 streetscape, limited to the cohesive and visual qualities of the street. That is why interiors are largely left alone and front elevations are not.
Council also identifies categories of minor building work in the overlay that may not need planning approval — enclosing under an existing building, an external stair or ramp, a carport at the front or side in specific circumstances, a carport, garage, shed or other outbuilding at the rear, and raising a house where the new height does not exceed 9.5 metres. The detail matters here, and it is set out in Council's City Plan rather than summarised well anywhere else, so treat that list as a prompt to check rather than as permission.
If your house is pre-1947, our companion guide to renovating a Queenslander or character home goes through what the overlay actually restricts in practice.
Building approval: what a certifier signs off
This is the approval most people miss, because it does not come from council and there is no obvious moment where someone asks you for it.
Brisbane City Council's guidance states plainly that you will need building approval before starting work on extensions, raising and renovations, and that you should contact a licensed building certifier for advice on your proposed work. In practice, the trigger is structural: if you are removing or replacing structural elements of the building, that is building work requiring assessment and approval.
The most common trigger on a renovation is removing an internal wall. Opening a kitchen into a living room is one of the changes owners ask for most often, and if that wall is carrying load — which in Brisbane's older housing stock it frequently is — the job now involves an engineer's design for a beam, and a certifier approving it.
Two points that catch people out:
- The certifier decides, not the builder and not the internet. A certifier can tell you in one conversation whether your specific job needs approval. That conversation is cheap and it happens before you commit to anything.
- It is your responsibility. The QBCC is explicit that it is the home owner's responsibility to make sure the right building approvals are in place before work starts, even if you have hired a builder. A good builder will manage the process for you; the obligation still sits with you, which is a reason to work with someone who treats approvals as part of the scope rather than as your homework.
The third layer nobody mentions: plumbing
Renovation articles almost never cover this, and it applies to nearly every bathroom, ensuite, laundry and kitchen job in Queensland.
Installing new or relocating fixtures such as toilets, showers, basins and kitchen sinks is notifiable work under Queensland's plumbing rules. Notifiable work is a category that a licensed plumber or drainer can carry out without a local government permit or mandatory inspections — but it is not unregulated. The plumber must register the work with the QBCC using a Form 4, within 10 business days of issuing an invoice for it.
Two practical consequences:
- Moving a toilet three hundred millimetres is regulated work, done by a licensed plumber, with a record attached to it. It is not a job for an unlicensed handyman, whatever the price.
- Ask for the Form 4 record and keep it with your renovation paperwork. It is evidence that the plumbing in your bathroom was done by someone licensed to do it, and it costs you nothing to have. A future buyer's solicitor will be pleased to see it.
What this means for three typical Brisbane jobs
A bathroom rebuilt in its existing footprint, post-war brick and tile house. Internal work only, so planning approval is unlikely to be in play. Whether building approval is required depends on what is being altered structurally — often nothing is, but the certifier makes that call, not us. The plumbing is notifiable work and gets registered.
A kitchen opened into the living room by removing a wall. Still internal, so again planning approval is unlikely — but the wall is the issue. If it is load-bearing you are into engineering and building approval, and that has a lead time which needs to sit at the front of the program, not in the middle of it.
A pre-1947 house in a character overlay, with any change to the exterior. Now you are in planning territory as well as building. This is the case where the approvals timeline genuinely shapes the project schedule, and where starting the conversation early is worth real money.
Where approvals sit in a well-run renovation
Approvals are the most common cause of a renovation stalling before it starts, and the cause is almost always sequencing rather than difficulty. The certifier needs drawings. The engineer needs a site inspection to produce the design the certifier needs. Council needs a complete application. None of that is hard, and all of it takes time that has to be spent before demolition rather than after.
On our projects the approvals path is worked out during the site assessment, before you receive a proposal, and the program you are given reflects it honestly. That is less exciting than a demolition date, and it is the difference between a renovation that runs and one that sits half-finished waiting for a document.
Common questions
- Do I need council approval for a bathroom renovation in Brisbane?
- If the bathroom stays inside the existing house and you are not altering the structure, it is unlikely to need planning approval — Brisbane City Council states that renovations only involving internal works are unlikely to need planning approval. Building approval is a separate question and depends on what you are changing; a building certifier can tell you in a short conversation. The plumbing work involved in relocating fixtures is notifiable work that your plumber registers with the QBCC.
- Does removing an internal wall need approval?
- If the wall is load-bearing, you are altering the structure of the building, and that is building work a certifier needs to assess and approve. Even where a wall looks non-structural, it is worth confirming before demolition rather than after — in older Brisbane homes, walls that were never designed to carry load often end up doing so after decades of movement and previous alterations.
- What is the difference between a building certifier and Brisbane City Council?
- Brisbane City Council administers the planning scheme — zoning, overlays, and what a development does to its surroundings. A building certifier assesses building work against the Building Code of Australia and Queensland's building laws, and issues the building approval. Private certifiers do most residential work in Queensland. Some jobs need a decision from both, some from one, some from neither.
- How long does approval take?
- It depends entirely on which approval you need. A straightforward building approval for internal work is typically a matter of weeks once the certifier has the drawings and engineering they need. A development application to Brisbane City Council for work in a character overlay is a longer and less predictable process. The honest answer is that approvals are the part of a renovation program most likely to slip, which is why they belong at the front of the schedule rather than the middle.
- What happens if renovation work was done without approval?
- Unapproved building work does not simply disappear. It tends to surface at the least convenient moment — usually during a sale, when a buyer's solicitor asks for the approval documents and there are none. Resolving it after the fact means opening up finished work so it can be inspected, which costs considerably more than doing it in the right order. If you have inherited unapproved work from a previous owner, a certifier can advise on what is involved in regularising it.
