Sheds and garages

Consumers must be aware of their responsibilities when constructing a shed or garage.

Where retailers suggest a consumer becomes an owner-builder, the owner-builder will be required to adhere to certain obligations under the Building Act 1993 and the Building Regulations 2018, particularly when selling their property.

If an owner-built shed or garage is sold within six and half years of the domestic building work being completed (i.e. from the date of your occupancy permit or certificate of final inspection), a defects report by a prescribed building practitioner is required.

Warranty Insurance may also be required if the shed or garage is sold within six years of the completion of building work.

When constructing a shed or garage, it is important to note:

  • 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 $10,000, 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 works over $10,000.
  • If the cost of the work (including labour and materials) exceeds $16,000 the builder or owner-builder is required to provide domestic building insurance.
  • The installation of roof sheeting, flashings, guttering, downpipes or other regulated plumbing work on a shed, regardless of scale, must be carried out by a licensed or registered plumbing practitioner. If the value of the plumbing work exceeds $750 a compliance certificate is required from a licensed plumbing practitioner.
