One of the very first questions homeowners ask us is whether their renovation needs council approval. It's a smart thing to check early, because getting it wrong can cause real headaches later. The honest answer is that it depends on what you're doing, but this guide will help you understand where you're likely to stand. (A quick but important note: this is general information to help you plan, not formal advice. Every project should be properly assessed before any work begins, because the details matter.)
Work that usually needs building approval and certification
As a general rule, the more your project affects the structure, the footprint, or the external appearance of the home, the more likely it needs approval. Work that typically requires building approval and certification includes:
- Structural changes, removing or altering load-bearing walls, for example, to open up a living space.
- Adding to the home's footprint, extensions and additions of almost any kind.
- Second-storey additions and house lifts (raise and build under), major structural work that always needs approval.
- New or relocated wet areas, adding a new bathroom, or moving plumbing and drainage.
- Decks and patios above a certain height off the ground.
- Most external alterations, and this is especially strict on character or heritage-affected homes.
Work that's often more straightforward
By contrast, some work is simpler from an approval standpoint:
- Like-for-like internal updates, replacing a kitchen or bathroom within the same footprint, without structural changes or major plumbing relocation, is often more straightforward (though wet-area work still has to meet standards and be done by licensed trades).
- Cosmetic work, painting, replacing flooring, installing new cabinetry, and similar surface-level updates generally don't trigger building approval.
Even here, though, "straightforward approval" doesn't mean "no standards." Waterproofing, plumbing, gas and electrical work all still have to be done properly and by the right licensed people, regardless of whether a formal building approval is needed.
The character and heritage factor
This is the one that catches the most Brisbane homeowners by surprise. Many of the city's inner and older suburbs have character or heritage overlays under the Brisbane City Plan. If your home falls under one of these overlays, external changes, particularly to the street-facing parts of the house, are much more tightly controlled and almost always require approval. Homeowners frequently don't realise their home is affected until they're well down the planning path, so it's worth checking early.
It's not a reason to avoid renovating a character home, these homes are wonderful and highly valued, but it does mean the right builder and the right process matter even more.
Who actually handles approvals?
For most residential building work, a private building certifier assesses and certifies the project against the National Construction Code and relevant standards. Some work, particularly anything triggering planning rules, like certain character-overlay changes, also needs council planning approval. It can sound daunting, but a good builder manages this entire process on your behalf: engaging the certifier, preparing what's needed, and making sure the work passes inspection. That coordination is a core part of what you're paying a licensed builder for.
Why it genuinely matters
It can be tempting to skip approvals for a quicker, cheaper job, but unapproved building work tends to come back to bite. It can cause failed inspections, serious problems when you try to sell the home (buyers' solicitors and lenders ask about approvals), complications with insurance if something goes wrong, and expensive rectification to bring non-compliant work up to standard. Done properly the first time, approvals protect both you and the value of your home, and they're far cheaper than fixing an unapproved job later.
The simplest path forward
If you're unsure, and most people are, because the rules genuinely are nuanced, the simplest thing is to talk to a licensed builder early in your planning. We'll tell you what your particular project is likely to need and handle the approvals process so it's done right from the start.
