Statutory Warranties Under the Residential Building Work Contracts Act 2016 (Tas)

What it is

Tasmania's Residential Building Work Contracts and Dispute Resolution Act 2016 (Tas) is the youngest statutory warranty regime in Australia. It commenced 1 January 2017 and replaced the older Housing Indemnity Act 1992 (Tas) framework. Sections 27 to 32 imply a set of statutory warranties into every residential building work contract and section 32(1) fixes the proceedings limit at 6 years from practical completion.

The Act carries the industry-standard warranty list but pairs it with a statutory definition of practical completion in section 4, which makes the completion date more provable than in states that leave it to the contract.

The statutory warranties

The Act implies the following warranties into every residential building work contract:

• the work will be carried out in a proper and workmanlike manner
• the work will be carried out in accordance with the plans and specifications for the work
• materials supplied will be of a merchantable quality and will be fit for the purpose for which they are being used
• new materials will be used unless otherwise agreed in writing
• the work will comply with the Building Act 2016 (Tas) and all other statutory requirements
• the work will be carried out with reasonable diligence
• the residential premises will be reasonably fit for occupation as a residence
• the work will be reasonably fit for any particular purpose the owner has made known to the building contractor

Any residential building work contract must include or be treated as including these warranties. The Director of Building Control's Determination on Mandatory Contract Provisions requires the contract itself to state them.

The 6 year proceedings limit runs from practical completion

Section 32(1) requires proceedings for breach of a statutory warranty to be commenced within 6 years after the date of practical completion. That measurement is unusually clean because section 4 of the Act supplies a statutory definition of the date of practical completion.

Section 4 defines the date of practical completion as the day by which three things are true. The work is completed in compliance with the contract including plans, specifications and statutory requirements. The work is completed without defects or omissions other than minor defects or minor omissions that will not unreasonably affect occupation. And, if the owner claims minor defects or minor omissions, the building contractor has given the owner a defects document for them.

Section 32(3) supplies a fallback cascade where that date cannot be established by reasonable diligence: the date a certificate of completion issues under the Building Act 2016, otherwise the occupancy permit date, otherwise 2 years after the building permit date, otherwise 2 years after building surveyor authorisation.

The defects document mechanic

Section 44 of the Act sits alongside the warranties. Where on or after the completion day the owner claims minor defects or omissions and the building contractor agrees they exist, the contractor must give the owner a defects document as soon as practicable. Section 44(3) then requires the contractor to correct the defect within 6 months after giving the defects document.

That 6 month period runs from the defects document rather than from practical completion. It is the statutory analogue of a defects liability period elsewhere in Australia, but narrower: it attaches only to defects recorded in a defects document.

Waivers void, contracting out prohibited

Section 78 of the Act voids any arrangement that defeats or evades the operation of the Act. That reaches contract terms that purport to exclude, shorten or narrow the section 27 to 32 warranties. TASCAT may also declare a term unjust under section 62(2) and vary or void it, weighing the factors in section 62(5).

No compulsory home warranty insurance stands behind the warranties

Tasmania has no compulsory home warranty insurance. The Home Warranty Insurance Amendments Act 2023 (Tas) passed but has not been proclaimed as at July 2026, and the Fair Trading (Home Building) framework that was scheduled to introduce compulsory cover is still on hold.

That absence is important. In every other state a statutory warranty regime is backstopped by a compulsory insurance scheme (icare HBCF in NSW, BPC Home Warranty in VIC from 1 July 2026, QBCC QHWIS in QLD, HII in WA, BII in SA, MBA Fidelity Fund in ACT, Fidelity Fund NT in NT). Tasmania has the warranties without the insurance backstop, which pushes owners onto the CBOS dispute pathway and, if necessary, TASCAT under section 62 for a money order or rectification.
