Licensed Bathroom Renovators in Tasmania — What CBOS Requires
In Tasmania, every licensed builder and tradesperson is registered with Consumer, Building and Occupational Services — CBOS. It’s the body that issues licences, maintains the public register, and sets the legal baseline for anyone performing building work in this state.
A CBOS licence isn’t a nice-to-have. It’s the legal difference between a contractor you can hold accountable and one you can’t — and it’s the foundation your statutory warranty protections, insurance coverage, and compliance certificates all rest on.
Every renovator Lifestyle Bathrooms works with in Tasmania holds a current CBOS licence. Verified before they’re engaged, confirmed against the class of work they’re being hired to do. Not a box-tick — it’s how we make sure you’re actually protected.
Tasmania’s Building Regulator — and One Detail Most People Miss
CBOS — Consumer, Building and Occupational Services — is a division of the Tasmanian Department of Justice. It issues and manages licences for builders, plumbers, electricians, gas-fitters, and other building services providers across the state. Licensing is governed by the Occupational Licensing Act 2005 (Tas), and if someone’s working on your home without a current licence from CBOS, they’re not just uncredentialled — they’re operating illegally.
That’s broadly true in most Australian states. But there’s a detail specific to Tasmania that’s worth understanding before you hire anyone, particularly if you’re getting quotes from contractors who work across state lines.
An Interstate Licence Doesn’t Work Here
Most Australian states have joined the Automatic Mutual Recognition scheme, which lets licensed tradespeople carry their credentials across state borders. Tasmania hasn’t — not for builders, not yet.
In practice, that means a builder who’s fully licensed in Queensland, NSW, or Victoria cannot automatically perform building work on a Tasmanian property on the strength of that licence. They need a current CBOS licence, full stop. If someone tells you their interstate credentials are good enough, they’re wrong — and it’s worth confirming before work starts.
CBOS maintains a free, publicly searchable register of all current Tasmanian licence holders. It takes about two minutes to check and the section below walks through exactly how.
Important for Tasmanian Homeowners
Tasmania has not joined the Automatic Mutual Recognition scheme for builders. An interstate building licence does not authorise work on your property here. Always verify your renovator holds a current CBOS licence — regardless of where else they’re licensed.
The Licences Your Renovator Actually Needs
Not all CBOS licences are the same, and the class matters. A licensee can only work within the scope they’re registered for — so when you’re hiring a bathroom renovation contractor, it’s worth knowing what to look for.
Builder (General Construction) — Domestic Subclass is the primary licence for contractors managing or carrying out renovation, alteration, addition, or repair work on residential buildings. It’s what your bathroom renovator should hold as head contractor. The General Construction licence also covers Low Rise, Medium Rise, and Open subclasses — relevant for apartments and multi-storey buildings — but for a standard house or townhouse bathroom, the Domestic subclass is the right scope.
Worth knowing: even if a contractor holds a higher-class licence, CBOS requires all licensees to work within their actual area of competence. An Open licence isn’t a blanket authorisation across every building type and complexity.
Plumbing and electrical are separate licences. The builder licence doesn’t extend to plumbing or electrical work. All plumbing and drainage must be carried out by a licensed plumber working to AS/NZS 3500. All electrical work must be done by a licensed electrician working to AS/NZS 3000. Both trades issue their own compliance certificates on completion.
Some contractors cut costs by using unlicensed labour for trade work. The law doesn’t allow for that. Neither do we.
The Two-Minute Licence Check You Should Run Before Signing Anything
CBOS provides a free public licence register at cbos.tas.gov.au called “Find a Licensed Tradesperson.” Search by name, trade category, or licence number. The register only shows current, active licence holders — so if your contractor doesn’t show up, their licence has either lapsed or it doesn’t exist.
Do this before you sign anything. It takes two minutes.
Three things to check when you pull up a result: the licence class should match the work being done (Domestic builder licence for a residential bathroom renovation), the status should be current, and there shouldn’t be any conditions or restrictions limiting the scope of what they’re authorised to perform. Ask for the licence number before you agree to anything. Any renovator worth hiring hands it over immediately.
Ask for the Licence Number
Request your contractor’s CBOS licence number before any contract is signed. A contractor who hesitates when you ask is already raising a flag worth paying attention to.
Go to the CBOS Licence Register
Visit “Find a Licensed Tradesperson” at cbos.tas.gov.au — it’s free, no login required, and lists all current Tasmanian licence holders.
Confirm Class, Status, and Scope
Enter their name or licence number and confirm the class is current and covers residential bathroom renovation work. Check for any conditions or restrictions on the registration.

This doesn’t need to be told as a horror story — it’s just the legal reality of what follows when a Tasmanian homeowner hires an unlicensed contractor for a bathroom renovation. And it’s fairly consistent every time.
Your statutory warranty rights under the Residential Building Work Contracts and Dispute Resolution Act 2016 only apply when the work is performed by a licensed contractor. Hire unlicensed, and that framework simply doesn’t apply. Doesn’t matter what the contract says, doesn’t matter how much you paid, doesn’t matter how good the tiles look on day one. If the work is defective and the contractor wasn’t licensed, you have no claim to make.
Home insurers assess whether licensed tradespeople performed renovation work before paying out a claim. Rectification from non-compliant work lands entirely on you. And compliance certificates can’t be issued by unlicensed contractors — their absence gets noticed at sale, refinance, or claim time. The money saved on an unlicensed quote tends to get spent again. Usually more than once.
No Statutory Warranty Protection
Your legal rights under the RBWCDR Act 2016 require licensed work. Unlicensed renovation sits entirely outside that framework — there’s no remedy available regardless of what a contract says.
Home Insurance Claims at Risk
Insurers check whether licensed tradespeople performed renovation work before paying claims. Unlicensed involvement gives them documented grounds to decline.
Rectification Falls Entirely on You
When unlicensed work fails, there’s no comeback. The cost of bringing a bathroom up to code after the fact comes out of your pocket — and it’s rarely cheap.
Compliance Certificates Won’t Exist
Unlicensed contractors can’t issue compliance documentation. Buyers’ solicitors, insurance assessors, and lenders all look for these — their absence creates problems you’ll eventually have to solve.
Your Statutory Warranty Rights — What Tasmania’s Law Actually Provides
When a licensed contractor completes residential building work in Tasmania, you’re entitled to statutory warranty protections under the Residential Building Work Contracts and Dispute Resolution Act 2016 — the RBWCDR Act. These aren’t something a contractor offers on top of a contract. They’re implied by law into every qualifying residential building work agreement in the state.
The Act covers residential building work contracts of $20,000 or more — a threshold that captures all substantial bathroom renovations. Your contractor warrants that the work will be completed in compliance with the contract and all statutory requirements; that materials supplied will be new and suitable for their intended purpose; that the work will be carried out with reasonable care and skill; and that it will comply with the National Construction Code and relevant Australian Standards. These don’t need to be written into the contract — they apply regardless.
Tasmania applies a single six-year warranty period from the date of practical completion — not a split between structural and non-structural categories as some other states do. If you sell the property before the six years are up, the warranties transfer to the new owner and run until the original period expires. There’s also a separate 10-year avenue under the Building Act 2016 (Tas) for loss resulting from defective building work — a distinct mechanism worth knowing about.
For disputes on contracts of $20,000 or more, CBOS offers free mediation. If that doesn’t resolve it, the matter can go to the Tasmanian Civil and Administrative Tribunal (TASCAT) — a more accessible alternative to the courts that makes binding orders.

These protections only apply when work is performed by a CBOS-licensed contractor. Unlicensed work sits entirely outside this framework — there’s no legal remedy available, regardless of what a contract says or how much was paid.
Owner Builders in Tasmania — What the Rules Actually Say
A CBOS Owner Builder Permit allows a property owner to manage building work on their own residential dwelling — but there are conditions attached that regularly catch people off guard.
Permits are only issued for Class 1a buildings: detached dwellings and conjoined units. Not investment properties you don’t intend to live in, not commercial buildings. Only two owner builder projects are allowed within any 10-year period, and once a project is complete you can’t continue performing additional work on that building under the original permit. Each new project needs its own new permit.
Insurance requirements are the same as for a licensed builder: contract works insurance and $5 million public liability insurance are mandatory. The statutory warranty protections under the RBWCDR Act apply to owner builder work on the same six-year terms as any other residential building contract.
The Part That Trips People Up
An Owner Builder Permit doesn’t give you the right to perform licensed trade work yourself. It covers the management and coordination of the project. Plumbing, electrical, and gas work on the bathroom still needs to be done by CBOS-licensed tradespeople — full stop. This catches a lot of people out, particularly investors who’ve done owner builder work in states where the rules are less prescriptive.
If you’re considering the owner builder route for a bathroom renovation, make sure you understand exactly what you’re permitted to do — and what still requires a licensed contractor.
⚠ Owner Builder Licensing Reminder
Owner builders cannot perform licensed trade work on a Tasmanian renovation. All plumbing, electrical, and gas work must be completed by CBOS-licensed tradespeople — regardless of the owner builder permit held.
Do You Need a Permit? The Honest Answer Is: It Depends on What You’re Doing
Tasmania’s Building Act 2016 categorises building work into three tiers: low risk, notifiable, and permit work. Where your renovation sits determines whether any formal approval is required before work starts.
For most standard bathroom jobs — swapping out fixtures in the same position, re-tiling a shower recess, updating tapware or vanity hardware — the work generally falls into the low risk category and no permit is required. That covers the majority of residential bathroom renovations.
It gets more nuanced once you start moving things around. Relocating plumbing fixtures, removing walls, or creating a new wet area where one didn’t exist shifts the project into notifiable or permit territory. Those jobs require a licensed building surveyor to be engaged — an independent professional whose job is to confirm the work meets the Building Act 2016 and the NCC at each stage and on completion.
Lifestyle Bathrooms assesses the permit category as part of the initial consultation, so you know exactly what approvals are required before anyone picks up a tool.
| Type of Work | Category | Permit or Approval Required? |
|---|---|---|
| Like-for-like fixture replacement | Low Risk | No |
| Retiling, cosmetic updates | Low Risk | No |
| Relocating plumbing fixtures | Notifiable / Permit | Often — confirm with your renovator |
| Removing or adding walls | Permit | Yes |
| Creating a new wet area | Permit / Notifiable | Usually — AS 3740 inspection required on completion |
| Full gut and rebuild | Depends on scope | Confirm with a licensed building surveyor |
How We Make Sure Every Tasmanian Renovation Is Actually Done Properly
Saying your contractors are licensed is easy. Here’s what the verification process actually looks like on a Lifestyle Bathrooms project in Tasmania.
Licence Verified Before Anyone Is Engaged
Every Tasmanian renovator in our network is checked against the CBOS public register before they’re listed or assigned to a job. We confirm the licence class matches the scope of residential bathroom renovation work — not just that a licence number exists somewhere.
Trade Licences Are Checked Separately
The builder licence doesn’t cover plumbing or electrical work, and we don’t treat it as if it does. Plumbers and electricians are independently verified for their CBOS trade licences before being assigned to any Tasmanian project.
Waterproofing Inspected Before Tiling Begins
AS 3740-compliant waterproofing is applied and inspected before a single tile goes down. That sign-off goes on file. Tiling doesn’t proceed until it’s confirmed — once the tiles are on, there’s no way to verify what’s underneath them.
Compliance Certificates Handed Over on Completion
Electrical certificate of compliance, plumbing compliance certificate, waterproofing sign-off — all collected when the job wraps and handed to you. Keep them with your property records. You’ll want them when you sell, refinance, or make an insurance claim.
Final Walkthrough Before We Leave the Site
Before the site is packed up, the bathroom is reviewed against scope, finish quality, and compliance requirements. If anything isn’t right, it gets sorted before we leave — not chased up in a callback next week.
