Owner builder - restrictions, home projects and farmers

An owner builder permit will only be issued for work on a residential building (detached dwelling or a conjoined unit).  Permission won’t be issued for any work on commercial buildings.  Restrictions include:

  • Only two owner builder projects are allowed in a ten-year period.  However those two projects can include two entirely new dwellings.
  • Owner builders cannot keep performing more work on what they have already constructed.  Each new building project must receive a new owner builder permit.
  • There is a fee for each owner builder permit (registration) issued
  • Owner builder insurance
  • Fee and insurance requirements for owner builders are the same as a licensed builder.

  • Notify your council if you are building a larger shed.

Home projects

  • Smaller sheds and outbuildings (Low Risk Buildings) are exempt from owner builder registration
  • The Building Act 2016 further simplifies the building approvals process.  A homeowner can build:
    • a shed, garage or carport up to 18m2, or up to 36mif prefabricated.
    • a porch or veranda up to 9m2, or a deck up to 1m high
    • a temporary swimming pool up to 9mwith a child safety fence
    • perform maintenance or repairs on a dwelling using similar materials as those replaced.
