Owner-builder terminology (QLD)

The state body that regulates building work, licensing, owner-builder permits, and the statutory insurance scheme.

A private or council-employed professional who issues building approvals, sets inspection stages, and issues final certificates.

Responsible for planning approvals (DA) and receiving final certification. Council does not manage inspections unless they are also the certifier.

Issued by QBCC. Allows you to personally take responsibility for building work over the monetary threshold. It does not approve construction.

Planning approval issued by council. Decides whether you may build what you propose on the land.

Issued by a certifier. Confirms the design complies with the Building Code and sets inspection stages. This is what lets construction legally start.

A mandatory checkpoint during construction (e.g. footing, slab, frame, final) where work must be inspected before continuing.

A certificate confirming an inspection or aspect of work complies. Often relied on by the certifier as evidence.

Common final certificate for single detached houses (Class 1a). Its issue date usually becomes the “completion date”.

Required for some building types. Confirms the building may legally be occupied.

Mandatory insurance for work done by licensed builders. It does not cover owner-builder work.

Optional private insurance covering damage to works in progress and materials on site.

Covers injury or property damage to third parties during construction. Strongly recommended for owner-builders.

The date your certifier issues the final certificate. This anchors the 6-year owner-builder disclosure period.

A written notice you must give a buyer before contract signing if selling within 6 years of completion.

An administrative note on the property title indicating owner-builder work. It can usually be removed after 6 years.
