What matters for building & renovation in Hobart

  • Tasmania scrapped the annual fire safety check. The Building Act 2016 replaced it with an approved schedule of maintenance for the building's essential building services, prepared by the owner and approved by a building surveyor, with maintenance done to that schedule rather than simply once a year.

  • Under section 206 of the Building Act 2016 a Tasmanian responsible owner must keep the maintenance records and produce them to an authorised officer or to the Tasmania Fire Service Chief Officer on request. Penalties reach 100 penalty units for an individual and 500 for a body corporate.

  • In Tasmania the responsible owner can be the tenant. Section 204 of the Building Act 2016 includes an occupier with a contractual responsibility to maintain the essential building services, as well as the owner and a strata body corporate.

  • Tasmania scales its dumping penalty by volume. Under section 9 of the Litter Act 2007 a load over 10 cubic metres reaches 200 penalty units for an individual and 500 for a body corporate, which is $42,600 and $106,500 at the 2026-27 penalty unit of $213.
