When does a Gold Coast repair need a QBCC-licensed trade?

In Queensland, the headline rule is a number: building work valued at more than $3,300 must be carried out by a QBCC-licensed contractor. That comes from the QBCC's own guidance on when a licence is required, and it is the single figure worth remembering.

What catches people out is what "valued at" covers. It is not just the labour. The figure is the reasonable total cost of having a licensed contractor do the job, with materials, labour and GST counted in, regardless of who supplies the materials. So a job where you buy the tiles and the contractor lays them still counts the tiles toward the threshold. It is easier to cross $3,300 than people assume.

There is also a lower line for one specialty: hydraulic services design needs a licence at anything over $1,100, not $3,300. For the everyday repairs most homeowners deal with, though, the $3,300 figure is the one that decides whether the person on site needs to be licensed.

Here is the part that surprises people. For a set of trades, there is no dollar threshold at all. A $200 job needs a licensed person just as much as a $20,000 one.

On the QBCC's list, the trades that are licensed regardless of value include plumbing and drainage, drainage on its own, gas fitting, chemical termite management, fire protection, mechanical services, completed residential building inspections, building design and site classification. The practical takeaway: if your repair touches plumbing, drainage, gas or fire safety, the value of the job is irrelevant. It needs a licensed specialist, full stop.

This is exactly why a service like ours dispatches rather than improvises. If you ring about what looks like a small job and it turns out to involve a gas connection or a drainage line, the right answer is a licensed plumber or gas fitter, not a generalist with a spanner. One number takes the brief; the correctly licensed person gets sent.

Waterproofing deserves its own mention because it is where homeowners most often get caught out. In Queensland, waterproofing is a regulated trade with its own QBCC licence. The scope covers applying, installing and repairing waterproofing, including the surface preparation underneath, and any material or system for preventing moisture penetration.

Why care? Failed shower and balcony waterproofing is one of the most common and most expensive building defects there is. Salt air and constant wet-area use on the Gold Coast do not help. If a membrane was put down by someone unlicensed and it fails two years later, the cost of ripping out and redoing the tiling lands on you.

So the question to ask before any bathroom or balcony re-tile is simple: who is doing the waterproofing, and are they licensed for it? A tiler tiles; the waterproofing layer beneath is its own licensed step. That is the same reason our bathroom and tiling work always brings in a licensed waterproofer with their licence number on the quote.

It is tempting to treat licensing as the tradesperson's paperwork problem. It isn't. The protection mostly runs to you, the owner.

The first reason is consumer cover. Queensland's Home Warranty Insurance Scheme can step in if a contractor abandons your job, becomes insolvent or leaves defective work behind. Using an unlicensed contractor can void access to that scheme, which means if the job goes wrong, the cost of putting it right falls on you with no safety net. Worth knowing: the scheme applies to residential building work, so it is a homeowner protection rather than something that automatically covers a body corporate's building.

The second reason is that unlicensed building work is treated as a real offence. The QBCC describes a zero-tolerance approach, and its own published example of a maximum court penalty for unlicensed work is $41,725 for an individual and $20,625 for a company. Those figures move with the value of a penalty unit, which is $166.90 from 1 July 2025. The point is not the exact dollar amount; it is that the law treats unlicensed work seriously, which tells you how much it wants the work done by someone qualified.

For body corporates the licensing question is about due diligence, not the Home Warranty Scheme. That scheme is residential-focused, so it is not the protection a committee should lean on. The real value for strata is risk management: a body corporate that engages an unlicensed contractor for common-area work carries the same defect-and-no-warranty risk a homeowner faces, with a building full of lot owners watching.

Checking that the contractor on a common-area job holds the right QBCC licence is part of prudent committee governance. It is verifiable in a minute, and it matters a great deal if a repair is ever questioned later. The work that crosses the $3,300 line on a building, common-area painting, balustrade repair, plasterboard, balcony waterproofing, is exactly the work where a current licence should be on file.

When we coordinate common-area repairs, the licence numbers of the specialists we dispatch go on the quote and into your records, so the paper trail is there before anyone asks for it.

Fences sit in a slightly different corner of Queensland law, governed by the Neighbourhood Disputes (Dividing Fences and Trees) Act 2011 rather than the QBCC alone. Worth a mention because it is one of the more common neighbour questions on the southern Gold Coast.

Under that Act, neighbours generally contribute equally to building and maintaining a dividing fence on the common boundary, and the fence is owned equally. A "sufficient" dividing fence for residential land sits between 0.5 and 1.8 metres high and is made substantially of the prescribed materials. To get a shared job moving you serve the neighbour a formal notice to contribute to fencing work, setting out the proposed work, at least one quote, and how the cost is to be split. If you cannot agree, the path runs through mediation and then QCAT.

Two things tie this back to the rest of the guide. Building or replacing a fence is not a QBCC-licensed activity in itself, but fencing work valued over $3,300 still falls under the general building-work licence threshold. And a taller boundary or dividing fence may need a building approval, so it is worth checking with the council before going high rather than assuming. We handle dividing fences, including the notice and the neighbour conversation, if you would rather not.
