The short answer
Tasmanian statutory warranties on residential building work last six years from practical completion, apply even if they are not written into the contract and pass to new owners if you sell. A 2023 Act also requires home warranty insurance, but we could not confirm when it starts.

The implied warranties include that materials are suitable and of good quality and that work is carried out with care and skill. They also apply to work done by owner builders.
How long you have
Warranties last six years from practical completion. A claim must be lodged with a court within six years, and complaints can be mediated for the same period.
Home warranty insurance
The Residential Building (Home Warranty) amendment Act 2023 requires a policy in force for insurable work that covers the owner and later owners for at least six years after practical completion, with cover set at a minimum of $200,000 or twenty percent of the contract price, whichever is lower. We did not find the start date, so check CBOS.
