There is one fact about building in Tasmania that every owner needs to understand before they sign anything, and most do not: Tasmania has no mandatory home warranty or builder’s insurance scheme. Not a weak one, not a limited one — none. New South Wales has the Home Building Compensation Fund. Victoria has Domestic Building Insurance. Queensland has the QBCC scheme. Western Australia has Home Indemnity Insurance. Tasmania has nothing equivalent.
The practical consequence is stark. If your builder becomes insolvent halfway through your renovation, there is no insurance product standing behind your contract. Nobody will finish the work. Nobody will refund what you have paid ahead. You join the queue of unsecured creditors, and in a builder’s collapse unsecured creditors typically recover very little.
The Tasmanian Government has at times operated a Financial Assistance Package for consumers affected by construction company failures. That is a genuine and welcome thing, but it is discretionary assistance, not insurance. It is not a right, it is not guaranteed to exist when you need it, and you cannot underwrite a $400,000 renovation on the hope of it.
What this means is simple and it should reorganise how you approach the whole project. In Tasmania, builder selection, financial due diligence and staged payment discipline are your real protection. They are not best practice here; they are the only protection there is.
Building a shortlist in a small market
Hobart’s trade base is small. The good renovation builders — particularly those who can work on old masonry, on steep sites, or in heritage precincts — are a knowable group, they are busy, and they are booked three to nine months ahead. That works in your favour if you start early and against you if you are in a hurry.

- Ask the professionals first. Building designers, architects, building surveyors, structural engineers and heritage consultants see the finished work and the paperwork. A surveyor who certifies twenty jobs a year knows exactly who is good.
- Ask the specialist trades. Stonemasons, plasterers and cabinetmakers know which builders pay on time, run an organised site and do not push them to cut corners.
- Look at completed projects like yours. A builder who is excellent at new houses on flat land in Kingston may be genuinely poor on a Battery Point cottage. The skills barely overlap.
- Neighbours with recent renovations are the most candid source you will find, and Hobart is small enough that this actually works.
- Be sceptical of anyone immediately available for a large renovation in this market. Sometimes it is a genuine gap in the programme. Often it is not.
- Shortlist three to four for pricing. More than that and you will not get considered quotes, because good builders can tell when they are one of eight.
- Start the conversation before your drawings are finished. The best builders will give you buildability input at design stage, and it will save you more than it costs.
The checks you must actually do
Licensing
Tasmania licenses a specific set of occupations, and it is worth knowing precisely which.
- Licensed: builders, building designers, electricians, plumbers and gas-fitters. Verify every one of these through CBOS (Consumer, Building and Occupational Services) before they set foot on the site.
- Not licensed in Tasmania: paving, concreting, painting and landscaping. There is no licence to check, so your due diligence on these trades has to be references, insurance certificates and written scope.
- Check the licence class and any conditions, not just that a licence exists. Classes carry limits.
- Check the name on the licence matches the entity on the contract. Contracting through a different company from the licensed one is a serious warning sign.
- Get certificates of currency for public liability and contract works insurance, dated and naming the correct entity.
Financial and company history
Because there is no warranty scheme, this is the check that matters most in Tasmania, and it is the one owners skip.
- ASIC company search on the exact contracting entity — directors, registration date, and whether the company was incorporated recently.
- Search the directors’ names for previous companies. A director with a string of deregistered or externally administered building companies behind them is the single clearest signal available.
- Check for external administration and any winding-up applications on the current entity.
- Personal Property Securities Register search for charges over the company’s assets.
- Court and tribunal records for TASCAT matters and civil judgments involving the builder.
- Ask for a bank reference and trade references from suppliers. A builder in good standing will provide these without fuss. Hesitation here is informative.
- Ask directly how many jobs they are running. Overextension is the most common cause of builder failure, and it is visible if you ask.
- Watch for cash-flow signals: pressure for a large deposit, requests to bring payments forward, suppliers chasing you for payment, or trades leaving site unpaid.
References and site visits
- Ask for three references: one completed within the last six months, one from two to three years ago, and one from a job that went wrong. Every builder has one; how they talk about it is the test.
- Visit a current site. Is it tidy, safe, protected from weather, with materials stored properly? A wet, disorganised Hobart site in winter tells you everything.
- Visit a completed job two or more years old. In this climate, defects show up in the second winter — condensation, mould in corners, failed junctions, damp at wall bases.
- Ask past clients specific questions: did the final cost match the contract; how were variations handled and priced; did the builder keep to the programme; were trades paid on time; did they come back to fix defects.
The contract: what Tasmanian law requires
The Residential Building Work Contracts and Dispute Resolution Act 2016 governs this, and its provisions are not optional.
- A written contract is mandatory for residential building work valued at $20,000 or more, covering new houses, renovations, alterations, extensions, improvements, repairs and conversions.
- Deposit caps: 10% for contracts between $20,000 and $50,000; 5% for contracts over $50,000; 20% where off-site work exceeds half the total price. The 5% cap over $50,000 is stricter than the mainland — a builder asking for 15% on a $400,000 job is asking you to break the law and to expose yourself.
- Progress payments cannot exceed 50% of the contract price until at least half the work is completed. This is your central protection against paying for work you will never receive.
- Statutory warranties are automatic and run for six years from practical completion, covering quality of materials, compliance with codes and laws, skilful workmanship, work carried out in accordance with the plans and specifications, and completion within the agreed time. They cannot be contracted out of.
Payment discipline is your insurance
Since no insurer will make you whole, the structure of your payment schedule is the substance of your risk management.
- Never pay ahead of the work. Every payment should follow a completed, inspected stage — not a date on a calendar.
- Stay behind the line at every point. Aim for the value of completed work to always slightly exceed the total you have paid.
- Have the building surveyor or an independent inspector confirm each stage before you release funds.
- Refuse front-loaded schedules. A schedule with 30% at slab and 30% at frame on a renovation is designed to get money out early.
- Price and sign every variation in writing before the work is done. Verbal variations are where projects and relationships both fail.
- Hold a meaningful final payment until defects from the completion inspection are actually rectified.
- Do not pay suppliers or trades directly to help a struggling builder’s cash flow. You take on the risk and lose your contractual position.
The building surveyor: your independent check
Tasmania’s system gives the building surveyor a role that mainland owners find unfamiliar, and it is genuinely valuable to you.
- You engage and pay the building surveyor, not the builder and not the council. They work for the compliance of the building, and their independence is real. Fees run $2,500–$8,000 for Category 3 or 4 work.
- They choose whether to certify. A surveyor who declines a project is telling you something you should listen to.
- They issue the Certificate of Likely Compliance before work starts, and a Notice of Work and Start Work Authorisation are lodged with council for Category 3 notifiable work.
- They inspect at nominated stages during construction.
- They can issue inspection directions and orders requiring defective work to be rectified — during construction and for up to two years after completion. This is a real enforcement power and owners underuse it.
- Category 4 permit work — triggered by owner-builder status or by a discretionary planning permit — additionally requires a formal building permit from council as permit authority.
- Choose the surveyor for your project type. One who has certified solid masonry, steep-site footings and cold-climate condensation detailing is worth far more than the cheapest quote.
Questions that reveal genuine Hobart knowledge
Ask these in the first meeting. The answers separate builders who understand this city from those who will learn on your project.
- “What do you allow for rock, and how do you price it?” A good answer references rock breaking at $250–$700 per cubic metre, distinguishes dolerite from sandstone, describes a provisional sum with a measured rate rather than a guess, and asks whether a geotechnical investigation has been done.
- “How do you deal with the fall on this block?” Listen for bored piers ($1,500–$3,500 each on rock), engineered retaining ($700–$1,800 per square metre of wall face), pole-frame or split-level construction, pumped concrete, craneage and materials handling. Someone who says “we’ll just cut and fill it” has not priced Hobart.
- “Who prepares the landslip hazard report and when?” The correct answer is a Civil Engineer, Geotechnical Engineer or Engineering Geologist meeting the Director of Building Control’s qualification requirements, at $3,500–$12,000, and done before the design is finalised. Not a builder, not a designer.
- “How would you repoint this wall?” The only acceptable answer for colonial sandstone or soft brick is lime mortar, at $120–$280 per square metre of wall face, raked out by hand. Anyone who says cement, or does not immediately understand why cement traps moisture and causes the stone to spall, should not be near a colonial building.
- “How do you manage condensation in a solid masonry wall?” Look for a grasp of vapour permeability, why you must not seal a solid wall from the inside with impermeable insulation, the NCC condensation management provisions, and ducted extraction discharging outside rather than into the roof space.
- “What’s your approach to draught sealing and ventilation together?” Sealing without a ventilation strategy causes mould. A good builder says so unprompted.
- “Have you built to BAL-29 or above?” On the elevated fringe this matters. Look for familiarity with Bushfire Hazard Management Plans by a TFS-accredited practitioner ($1,500–$5,000), Hazard Management Areas, shutters, screening, glazing, sarking and decking requirements.
- “What are your current lead times on windows, steel and joinery?” Bass Strait freight is real. A builder who quotes mainland lead times has not ordered anything lately.
- “How do you programme around a Hobart winter?” Wet, cold winters genuinely stop external work, and lime work needs warm, protected curing conditions. The right answer sequences external and masonry work into the warmer months.
- “What’s your asbestos process?” Survey $400–$900, licensed removal $2,500–$15,000, and a clear answer on who holds the licence.
Reading a quote properly
- Compare inclusions, never headline prices. The cheapest quote is usually the one with the least in it, and the difference emerges as variations.
- Look for the exclusions list. A good quote has one and it is honest. No exclusions list means they are all coming later as variations.
- Interrogate provisional sums and prime cost items. A $12,000 PC allowance for a kitchen you have specified at $40,000 is not an oversight, it is a lower headline number.
- Check the site works allowance specifically. On a Hobart block this is where the money hides: rock, retaining, piering, access, spoil, pumped concrete, crane.
- Check who pays for what fees — designer, engineer, building surveyor, landslip report, bushfire plan, planning fees.
- Look for a programme with dates, not just a duration, and a stated approach to weather delays.
- Check the payment schedule against the legal caps before you look at anything else.
- Confirm the defects liability period and how defects will be handled — separately from, and in addition to, the six-year statutory warranties.
Red flags
- A deposit above the statutory cap — 10% between $20,000 and $50,000, 5% above $50,000.
- Pressure to sign quickly, or a price that expires in days.
- No written contract on work of $20,000 or more. This is a breach of the law, not a shortcut.
- A price dramatically below the others. In a small market with known input costs, a 30% gap is not efficiency.
- Cash discounts or a request to pay a different entity from the one on the contract.
- Vagueness about licence details, insurance certificates or company history.
- No fixed address, no site presence, no supervisor you can name.
- Requests to bring payments forward mid-project, or trades and suppliers contacting you about unpaid accounts.
- Reluctance to work with the building surveyor you have engaged.
If it goes wrong: the dispute pathway
Tasmania has a defined escalation path, and the later steps are closed to you if you have skipped the earlier ones.
- 1. Direct negotiation. In writing, specific, dated, with a reasonable timeframe for response. Keep every record — this becomes the evidence that you attempted genuine negotiation.
- 2. The building surveyor. On anything touching code compliance, they can issue inspection directions and orders for defective work, during construction and for up to two years after completion. This is often the fastest and cheapest resolution available and it costs nothing extra.
- 3. Free informal advice from CBOS. Consumer, Building and Occupational Services will advise on your position and frequently resolve matters through informal contact with the builder.
- 4. Formal mediation through the Director of Building Control — a 20-day process with mediator costs shared between the parties. Take it seriously; a large proportion of disputes settle here.
- 5. TASCAT, the Tasmanian Civil and Administrative Tribunal. Note carefully: TASCAT cannot hear a dispute where genuine negotiation and mediation have not been attempted, or where the contract predates 1 January 2017. Skipping the earlier steps does not accelerate the process; it disqualifies you.
- And note what is not on this list: an insurer. If the builder is insolvent rather than merely difficult, the dispute pathway leads to a company with no assets. Which is why the checks at the front end matter so much.
For the cost benchmarks you will be measuring quotes against, see the 2026 Hobart renovation price guide, and for what the approval process asks of your builder, the 2026 council approval rules. If the work involves early fabric, test your shortlist against the technical material in renovating a colonial cottage and heritage and character controls. For steep-site and overlay economics, home extensions in Hobart covers the ground, and it is worth reading the most expensive mistakes people make here before you sign anything.
A view on choosing a builder in Tasmania
In a state with a mandatory warranty scheme, a bad builder choice is an expensive inconvenience. Someone pays to finish the work. In Tasmania, a bad builder choice can simply take the money. That asymmetry should change your behaviour, and for most owners it does not, because the absence of the scheme is invisible until the day it matters.
So do the unglamorous things. Spend two hundred dollars on company searches. Read the licence class. Ask for the bank reference and notice whether it arrives. Refuse the deposit above the cap even when the builder is charming and you want the job to start. Have the surveyor sign off before every payment. Walk away from the cheap quote.
None of this is adversarial, and good Hobart builders — of whom there are many — will not blink at any of it. They have seen the collapses too, they have watched clients lose money to people who should never have held a licence, and the ones worth hiring understand precisely why you are asking.
