Looking to hire a licensed builder in Tasmania for a renovation in Battery Point, a new home in Sandy Bay, or an extension in Launceston? The builder you pick will determine whether your project runs smoothly or turns into an expensive headache. Tasmania’s building industry is smaller than the mainland states, which means word gets around fast, but it also means fewer options and longer wait times if you get it wrong. This guide covers everything you need to know to hire a builder in Tasmania with confidence. From checking CBOS building licences to understanding deposit limits, contract rules, warranty protections, and what to do when things go sideways, it is all here. Start by browsing licensed builders in TradieVerify’s builder directory.
Why You Need a Licensed Builder in Tasmania
Consumer Building and Occupational Services (CBOS) regulates building work in Tasmania. If you are having residential building work done, the building services provider carrying out the work must hold a current CBOS building licence. This is a legal requirement under Tasmanian law.
Legal protection. A licensed builder in Tasmania has met formal qualification requirements and demonstrated practical experience. Their work must comply with the National Construction Code and all applicable Tasmanian building regulations. Hiring a licensed builder means the person working on your home has been vetted by the regulator.
Statutory warranties. When you hire a licensed builder in Tasmania, you receive statutory warranties under the Residential Building Work Contracts and Dispute Resolution Act 2016. These give you 6 years of cover for structural defects and 2 years for non-structural workmanship issues. These warranties cannot be excluded or watered down by the contract.
Accountability. Licensed builders are registered with CBOS. If there is a dispute, you can lodge a formal complaint and CBOS has powers to investigate, issue directions through the Director of Building Control, and refer matters to TASCAT. With an unlicensed operator, you are left chasing them through the courts with no regulatory backup.
Penalties for unlicensed work. If you knowingly hire an unlicensed tradesperson, you may not be covered by statutory warranties or the future home warranty insurance scheme. That leaves you completely exposed if something goes wrong.
You can check any Tasmanian builder’s licence status on TradieVerify’s search page in seconds.
How to Check a Builder’s Licence in Tasmania
Before you sign anything or hand over a deposit, verify the builder’s licence. This takes a few minutes and could save you tens of thousands of dollars. Here is how to check a Tasmania builder licence.
Step 1: Use TradieVerify search. Head to TradieVerify’s licence search and enter the builder’s name or licence number. TradieVerify cross-references CBOS data so you can confirm their licence status, class, and scope in one place. This is the fastest way to run a Tasmania builder licence check.
Step 2: Verify on the CBOS portal. For a second check, visit the CBOS Occupational Licensing portal. Search by licence number or name and confirm the details match what the builder provided.
Step 3: Check PlanBuild Tasmania. You can also verify a builder’s credentials at planbuild.tas.gov.au under the “Find a Licensed Professional” section. This gives you another independent confirmation that the licence is current and active.
What to check on the licence:
- Licence number — does it match the number on their quote and marketing materials?
- Licence class and sub-class — is it appropriate for your project type? (See licence classes below.)
- Scope of work — does the scope cover your specific project? A builder licensed for domestic work cannot take on medium-rise construction.
- Expiry date — is the licence current, not expired or suspended?
Red flag: contract signer must match licence holder. The person who signs your building contract must be the actual CBOS licence holder, or an authorised representative of the licensed company. If someone else signs, your contract may not be valid and your statutory warranty protections could fall away.
You can also browse licensed builders in TAS on TradieVerify to find verified builders in your area.
Understanding Tasmania Builder Licence Classes
Not all builder licences are the same in Tasmania. CBOS issues different licence classes based on the type and scale of building work. Before you hire a licensed builder in Tasmania, make sure their licence class matches your project.
Builder (General Construction)
| Sub-Class | Scope |
|---|---|
| Domestic | Residential dwellings only (Class 1 and 10 buildings) |
| Low Rise | Buildings up to 2 storeys |
| Medium Rise | Buildings up to 3 storeys |
| Open | No height or scope restrictions |
Other Builder Licence Classes
| Licence Class | Scope |
|---|---|
| Builder (Fire Protection Services) | Installation and maintenance of fire protection systems. Also has Low Rise, Medium Rise, and Open sub-classes. |
| Builder (Demolisher) | Demolition work. Also divided into Low Rise, Medium Rise, and Open sub-classes. |
For a standard house build or renovation, you need a builder with at least a Builder (General Construction) - Domestic or Low Rise licence. If the project involves a multi-storey build or commercial elements, Medium Rise or Open is required.
One thing that catches mainlanders off guard: carpenters, concreters, and bricklayers are not separately licensed trades in Tasmania. These workers operate under the builder licensing framework, so your licensed builder takes responsibility for their work. This is different from states like Queensland and New South Wales.

Tasmania Warranty Protections and Home Warranty Insurance
Warranty protections are a major reason to hire a licensed builder in Tasmania rather than taking a chance on an unlicensed operator.
Statutory warranties under the Act. The Residential Building Work Contracts and Dispute Resolution Act 2016 provides statutory warranties on all residential building work. These include:
- 6 years for structural defects from the date of practical completion
- 2 years for non-structural workmanship defects from the date of practical completion
These statutory warranties apply automatically. They cannot be excluded, limited, or overridden by anything in your building contract Tasmania. If a builder tells you warranties do not apply, they are wrong.
New Home Warranty Insurance scheme. Tasmania is introducing a Home Warranty Insurance (HWI) scheme. Once fully operational, builders will need to purchase HWI for residential building contracts over $20,000. The scheme will cover:
- 5% of the contract value for deposit losses
- 20% of the contract value for incomplete or defective work
- Up to $200,000 maximum claim
Until the HWI scheme is fully operational, statutory warranties remain your primary protection. The builder must also provide you with the Residential Building Consumer Guide before you sign the contract. This document explains your rights and is a mandatory requirement.
Financial Assistance Package. Tasmania also has a Financial Assistance Package available for consumers affected by construction company failures. This provides a safety net while the HWI scheme is being rolled out.
TAS Contract Requirements and Deposit Limits
Tasmania has clear rules that protect homeowners when you enter a building contract Tasmania. These protections are set out in the Residential Building Work Contracts and Dispute Resolution Act 2016.
Written contract is mandatory for residential building work. Verbal agreements leave you exposed.
Deposit Limits
The maximum deposit a Tasmanian builder can charge is 5% of the contract value. Any builder who asks for more than this is breaking the law. If someone demands 20% or 30% upfront, walk away.
Cooling-Off Period
You have a 5 business day cooling-off period after signing a residential building contract. During this time, you can cancel the contract. Use this period to get independent advice if you have any doubts.
Mandatory Contract Inclusions
Under the Act, your building contract must include:
- Builder’s CBOS licence number
- Full scope of work to be performed
- Contract price (or how it will be calculated)
- Start and completion dates
- Deposit amount (maximum 5%)
- Progress payment schedule tied to building stages
- Warranty information
- Dispute resolution procedures
Residential Building Consumer Guide
The builder must give you a copy of the Residential Building Consumer Guide before you sign the contract. This is not optional. The guide explains your rights, the complaints process, and what protections apply. If a builder does not hand you this guide, ask for it before signing anything.
Progress payments must follow a defined schedule tied to actual building stages. You have the right to inspect work before paying each stage claim.

How to Get and Compare Quotes in Tasmania
Getting multiple quotes is standard practice, and it matters even more in Tasmania where the builder pool is smaller. Aim for at least 3 written quotes before deciding who to hire as a builder in Tasmania.
What a Tasmanian builder quote should include:
- Builder’s full name and CBOS licence number
- ABN (Australian Business Number)
- Detailed scope of work
- Itemised pricing for each stage or component
- Prime cost items and provisional sums clearly listed
- Timeline with start and completion dates
- Inclusions and exclusions stated clearly
Comparing quotes — the right way: Compare like-for-like. One builder may quote $450,000 for a new build in Hobart while another quotes $380,000, but the cheaper quote might exclude site preparation, landscaping, and driveways.
Island logistics matter. Being on an island adds 10-15% to material costs compared to mainland capitals. Materials need to be shipped across Bass Strait, and that cost flows through to your quote. Limited builder availability in regional areas like the West Coast, Huon Valley, and East Coast can also push prices higher due to travel and accommodation.
Ask each builder: What is your CBOS licence class? Can you provide references from recent clients? Have you worked on similar projects in this area?

Red Flags When Hiring a Tasmanian Builder
The warning signs are consistent across Australia, but some are especially relevant in Tasmania’s smaller market. If you spot any of these when trying to find a licensed builder in Tasmania, proceed with caution or walk away.
-
Asking for cash payments to avoid GST. No paper trail means no recourse if something goes wrong. Insist on invoiced payments every time.
-
No CBOS licence number on quotes or marketing materials. A licensed builder should display their licence number on all business documents. If it is missing, ask for it and verify it.
-
No Residential Building Consumer Guide provided before signing. This is a legal requirement. If the builder does not hand you this guide, they are either ignorant of the law or deliberately withholding your rights. Both are bad signs.
-
Pressure to sign the contract quickly. You have a 5 business day cooling-off period. Any builder who rushes you past this is a red flag.
-
Quote significantly below all other quotes. If one quote is 30-40% cheaper than the rest, the builder is either underquoting to win the job (then hitting you with variations) or cutting corners on materials and labour.
-
No fixed business address or ABN. A legitimate Tasmanian builder has a registered business address and an active ABN you can verify on the Australian Business Register.
-
Cannot provide references from recent clients. In Tasmania’s tight-knit building community, every established builder should be able to provide contact details for recent clients. Refusal is suspicious.
-
Wants to start work before the contract is signed. No signed contract means no statutory warranty protections and no access to the CBOS complaints process.
-
Different person signs the contract than the licence holder. The contract must be signed by the CBOS licence holder or their authorised representative. If someone else signs, your protections may be void.
-
Licence sub-class does not match your project. A builder licensed for domestic work only cannot legally take on a low-rise commercial fitout. Always confirm the scope of their licence covers your specific project type.
Owner-Builder Permits in Tasmania
If you are considering managing the build yourself rather than hiring a builder in Tasmania, you will need an owner-builder permit. Here is what the rules look like.
Course requirement. You must complete an approved Tasmanian owner-builder course within the last 12 months before applying. This course covers your legal obligations, safety requirements, and project management basics.
Key restrictions:
- Owner-builder permits are only available for residential buildings (Class 1a)
- Maximum 2 projects per 10-year period — you cannot use this as a way to build and flip properties repeatedly
- All owners listed on the Title must be part of the application
- You must hold a current White Card (construction induction card)
Small works exemptions. Some smaller projects do not require an owner-builder permit:
- Shed, garage, or carport up to 18 sqm (or 36 sqm for prefabricated structures)
- Porch or veranda up to 9 sqm
- Deck up to 1 metre in height
Insurance and fees. As an owner-builder, you carry the same insurance and fee obligations as a licensed builder. You are also responsible for all workplace health and safety on site.
For a full breakdown of owner-builder rules across all states, read the owner-builder permits guide.
What to Do If Something Goes Wrong: CBOS Complaints and TASCAT
Even with thorough preparation, building projects can hit problems. Tasmania has a structured dispute resolution process through CBOS and TASCAT. Knowing the steps helps you act quickly.
Step 1: Notify the builder in writing. Put your complaint in an email or letter. Describe the problem clearly, reference your building contract, and give the builder 14 days to respond. Keep copies of all correspondence.
Step 2: Contact CBOS. If the builder does not respond or you cannot reach a resolution, contact Consumer Building and Occupational Services. Call 1300 654 499 or email CBOS.info@justice.tas.gov.au. CBOS handles complaints about defective work, incomplete work, and licensing breaches.
Step 3: Mediation through the Director of Building Control. CBOS can refer your dispute to the Director of Building Control for mediation. This is a free service with no application fees. Mediation aims to resolve the issue without going to a tribunal, and many disputes are settled at this stage.
Step 4: TASCAT for unresolved disputes. If mediation does not resolve your issue, you can apply to the Tasmanian Civil and Administrative Tribunal (TASCAT). TASCAT has jurisdiction for residential building work disputes and can:
- Order the builder to rectify defective work
- Award financial compensation
- Make binding decisions on contract disputes
- Terminate contracts in serious cases
Keep records of everything. Photos, emails, contracts, invoices, and any communication with the builder. Good documentation strengthens your position at every stage of the process.
For detailed advice on handling disputes, read the building disputes guide.
How Much Does a Builder Cost in Tasmania?
Builder costs in Tasmania vary depending on project type, location, and finish level. Here are typical ranges to help you budget before you hire a licensed builder in Hobart, Launceston, Devonport, or regional areas.
Common Project Costs in TAS
| Project Type | Typical TAS Price Range |
|---|---|
| New home build (standard) | $1,800 - $2,800 per sqm |
| New home build (premium) | $3,000 - $4,500+ per sqm |
| Full renovation | $1,200 - $3,500 per sqm |
| Kitchen renovation | $18,000 - $50,000 |
| Bathroom renovation | $12,000 - $35,000 |
| Granny flat | $90,000 - $200,000 |
| Deck or pergola | $10,000 - $30,000 |
| Home extension | $2,000 - $3,500 per sqm |
Factors Affecting Tasmania Builder Cost
- Island logistics. Materials shipped across Bass Strait add 10-15% to material costs compared to mainland capitals. This is the single biggest factor that makes Tasmania builder cost higher than equivalent projects in Melbourne or Sydney.
- Location within Tasmania. Hobart metro is the most competitive market with the widest choice of builders. Regional areas like the West Coast, East Coast, and Huon Valley cost more due to transport, travel time, and limited local builder availability.
- Site conditions. Many Tasmanian building sites are sloped, heavily treed, or have difficult access. These factors add to excavation and preparation costs.
- Heritage considerations. Areas like Battery Point, Salamanca, and parts of Launceston have heritage overlay requirements that can increase costs and approval timeframes.
- Market conditions. Tasmania’s smaller builder pool means demand fluctuations have a bigger impact on pricing and availability. Book well ahead.

Frequently Asked Questions
Do I need a licensed builder for all work in Tasmania?
A licensed building services provider is required for residential building work in Tasmania. Minor maintenance and repair work may not require a licence, but any structural work, new construction, or significant renovation should always be done by a licensed builder. If in doubt, check with CBOS or search for a builder on TradieVerify.
How do I verify a CBOS building licence is current?
The fastest way is to search on TradieVerify, which cross-references CBOS data and shows licence status, class, and scope. You can also search directly on the CBOS Occupational Licensing portal or PlanBuild Tasmania at planbuild.tas.gov.au. A quick Tasmania builder licence check before signing the contract protects you from unlicensed operators.
What is the maximum deposit a Tasmanian builder can charge?
The maximum deposit is 5% of the contract value under the Residential Building Work Contracts and Dispute Resolution Act 2016. Any builder asking for more than 5% is acting outside the law. Report excessive deposit demands to CBOS.
What statutory warranties apply in Tasmania?
Statutory warranties give you 6 years of protection for structural defects and 2 years for non-structural workmanship issues from the date of practical completion. These warranties apply automatically and cannot be excluded by your building contract. They are your primary protection until the new Home Warranty Insurance scheme is fully operational.
How do I lodge a complaint about a Tasmanian builder?
Start by notifying the builder in writing and giving them 14 days to respond. If that does not resolve the issue, contact CBOS on 1300 654 499 or email CBOS.info@justice.tas.gov.au. CBOS can investigate and refer the matter for mediation through the Director of Building Control. For more steps, see the building disputes guide.
Can I be an owner-builder in Tasmania?
Yes, but you must complete an approved Tasmanian owner-builder course within the last 12 months, hold a White Card, and apply for a permit. You are limited to 2 projects per 10-year period, and only for residential Class 1a buildings. All owners on the Title must apply together. Read the full owner-builder permits guide for details.
What is the Residential Building Consumer Guide?
The Residential Building Consumer Guide is a document your builder must give you before you sign the building contract. It explains your rights, the statutory warranty protections, the complaints process, and other key information. If a builder does not provide this guide, do not sign until they do. It is a mandatory requirement under Tasmanian law.
Are carpenters and bricklayers licensed in Tasmania?
No. Unlike some mainland states, Tasmania does not separately licence carpenters, bricklayers, or concreters. These trades operate under the builder licensing framework. Your licensed builder is responsible for the work carried out by these tradespeople on your project. Check the TAS state page for more on how licensing works in Tasmania.
