Most domestic sheds and garages require a building permit. If a building permit is required and the building work, including supply and installation, costs more than $5,000, unless you are an owner-builder, you must use a registered building practitioner to carry out the work.
A major domestic building contract must be entered into with the registered building practitioner for work over $5,000.
If the cost of the work (including labour and materials) exceeds $16,000 the builder is required to provide domestic building insurance.
The installation of roof sheeting, flashings, guttering and downpipes on a shed, regardless of scale, must be carried out by a licensed or registered plumbing practitioner:
- If it is connected to a stormwater collection or disposal system
- If the value of the roof plumbing work exceeds $750 a compliance certificate is required from a licensed plumbing practitioner
