Licences. The QBCC licenses building work in Queensland, and its advertising rules (the licensed name, licence number and a statement that you're licensed under the QBCC Act, on your website as much as your ute) are set out on our page for Brisbane builders. What's particular to bathrooms is the licence class. Queensland has a builder licence restricted to kitchen, bathroom and laundry installation: it covers installing, refurbishing, restoring and repairing those rooms in houses, and in class 2 to 9 buildings, which include apartment blocks, only where the room's gross floor area is 50 square metres or less. It doesn't extend to work that may affect the structural performance of the building, and the holder can't personally do work that needs an occupational licence, such as plumbing, unless they hold that licence too. Waterproofing is a trade class of its own, and the wall and floor tiling class includes waterproofing done for tiling. Plumbing and drainage need a QBCC licence whatever the job is worth.
Units and the home warranty gap. At the 2021 Census the City of Brisbane had 465,124 occupied private dwellings, and 118,894 of them were flats or apartments. About 58,000 of those were in blocks of four storeys or more, and that height matters: Queensland's building regulation leaves work on a multiple dwelling of more than three storeys out of the Home Warranty Scheme (the QBCC doesn't count one storey that is mainly car park), and its own example is renovating the bathroom of a single unit in a 10-storey building. Ownership lines matter too. Multi-storey unit blocks are usually on a building format plan, where the boundary between a lot and its neighbour or the common property runs through the centre of the floor, wall or ceiling. Pipes and wiring inside those boundary structures, or serving more than one lot, are common property that the body corporate maintains. The owner looks after fixtures and fittings inside the lot and, in a community titles scheme, the shower tray their lot uses even where it sits outside the boundary. Changes an owner makes to common property generally count as improvements, which need approval from the committee for smaller jobs or an ordinary resolution at a general meeting.
Plumbing paperwork. Queensland's plumbing regulation sorts work into categories. Replacing a fixture where it already stands is minor work. Installing or relocating a fixture in a house is notifiable work: the plumber lodges a Form 4 with the QBCC once it's finished and gives the owner a copy, and Brisbane City Council's plumbing page names new fixtures in bathroom and kitchen renovations as typical notifiable work. For unit buildings, the notifiable list only takes in buildings of one or two storeys, and even there not the sanitary drainage, so in a taller block a relocated toilet or shower may need a Council plumbing permit before work starts. The QBCC has a questionnaire for checking which applies. Council also sells copies of the drainage plans it holds for houses and offers virtual viewings, so you can see where the drains run before pricing a new layout. Our Brisbane plumbers page covers the QBCC side in more detail.
Older homes and rentals. Queensland's asbestos website says asbestos cement sheeting was common from the 1940s to the late 1980s and was often used for wall and ceiling sheets inside houses, particularly in wet areas such as bathrooms. It rates a house built before the mid-1980s as highly likely to contain some, warns that earlier renovators sometimes sheeted straight over it, and says the felt backing on older vinyl sheet flooring is friable and must be removed by a Class A licence holder. Removing any friable asbestos, or more than 10 square metres of the non-friable kind, needs a licence. Rentals are the other large market: about 38 percent of the city's occupied homes were rented in 2021, including two in three apartments. Since 1 September 2024 every Queensland tenancy has had to meet minimum housing standards, among them bathrooms that give privacy, toilets that flush, adequate plumbing and drainage, and premises free of damp and mould. A landlord who wants tenants to pay for all the water they use also needs efficient fittings: showerheads and the cold taps over basins, sinks and laundry troughs flowing at no more than 9 litres a minute, and dual-flush toilets using no more than 6.5 litres on a full flush and 3.5 on a half.
People search by suburb, so it helps to name Bulimba, Wilston or Indooroopilly rather than writing "Greater Brisbane". List the suburbs you'll quote in, add any in neighbouring Moreton Bay, Logan, Ipswich or Redland if you cross council lines, and say plainly whether you take high-rise jobs. WebCraft Studio is an Adelaide team at Ste 3/110 Hutt St, so Brisbane renovators work with us by phone and email: you send your words, licence details, photos and suburb list, we send a draft link, and you pay once you've approved it.
