Underpinning Licensing & Rules in Tasmania
Important regulations and resources to help you hire with confidence in Tasmania.
Building work approval
Underpinning is building work and requires an approval based on risk. High-risk permit work needs a building permit from council, engineered design, a licensed builder and inspection by a building surveyor before work starts.
Licensed building practitioner
Builders performing building work must hold a relevant building services provider licence under the Occupational Licensing Act 2005. Only licensed practitioners can undertake or supervise underpinning.
Notice of work and certification
For notifiable work, a Notice of Work and Certificate of Likely Compliance must be lodged with council. Work cannot commence until accepted by the permit authority.
Occupancy permit
An occupancy permit must be issued before a building can be occupied after structural work. The building surveyor verifies that the work complies with the Building Act and National Construction Code.
General construction induction card
All persons entering a construction site must hold a White Card obtained from an approved training provider.
Insurance requirements
Builders should maintain public liability, workers compensation and, where applicable, home warranty insurance to protect owners against incomplete or defective work.
