If the value of the proposed domestic build work is more than $16,000 (including labour costs and materials), you must apply for a certificate of consent from the Victorian Building Authority (VBA) to become an owner-builder.
You must obtain a building permit before you commence building works, and be named as the owner-builder on that permit.
It is your responsibility to ensure that the work meets:
You must arrange for building inspections as required by your building permit at particular stages of the building work.
You must obtain an occupancy permit, or certificate of final inspection from the relevant building surveyor once work is completed.
