   Above 10,000 dollars of work on your own home, yes — where you are supervising or doing it rather than engaging a licensed builder to supervise. The permit is what makes that legal.

   Above 20,000 dollars there is a second hurdle: you have to complete certain units of competency, or hold approved equivalent qualifications and experience. A white card from SafeWork NSW, or an equivalent interstate qualification, is required either way.

   The part that is easy to miss is what the permit does to you rather than for you. As an owner-builder you are just as responsible for the building work as a fully licensed builder would be — which means the warranties other people rely on are now yours to give, not yours to receive.

   That is also why the Consumer Building Guide warns about a builder who suggests you take out an owner-builder permit while they organise the work. That arrangement moves the responsibility onto you and can mean they do not hold the right licence or the right insurance cover for the job at all.
