What matters for building & renovation in Devonport

  • Devonport Airport records a mean 3pm wind speed of 24.1 km/h across the year, rising to 26.9 km/h in December, because the north west coast faces straight into Bass Strait. Roof sheeting, flashings, fascia and fixings on an exposed Devonport block take a much harder beating than inland Tasmania.

  • Devonport gets 764 mm of rain across 130 days a year, and 15 to 16 of those rain days fall in each of July and August. Fixed price outdoor jobs quoted over a Devonport winter should say who wears the weather delays.

  • 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.
