Review of the residential home building laws


The New South Wales Government is reviewing the residential home building laws. Visit the Review of the home building legislation page to read more and to download the position paper which outlines the 50 proposed changes to the current laws.


You must have a contractor licence to contract, subcontract or advertise to do:

  • residential building work where the total cost of labour and materials is more than $1,000
  • electrical wiring work
  • plumbing, draining and gas fitting work
  • air conditioning and refrigeration work (except plug-in appliances).

Licensing helps stamp out illegitimate operators from the industry and creates a level playing field for all tradespeople.

Caution. By law, your licence number must be shown on all advertising, stationery and signage.

If you work without the proper licence, you are breaking the law and can be fined. Also, you will be unable to enforce a contract for the work against the other party.
