Home building insurance and deposits

Home indemnity insurance is required for building work that needs a building permit and is valued at more than $20,000.

The maximum deposit is 6.5% for contracts between $7,500 and $500,000.

Check more than the licence

A current licence doesn’t tell you whether the business is in financial trouble. These national registers cover businesses in every state:

ABN Lookup: Confirms the ABN is active and who it belongs to.
ASIC published notices: Liquidation, administration and winding-up notices.
ASIC banned and disqualified register: People banned from managing companies.
