Renovation permits and contractor licences in South Australia
South Australia licenses by activity rather than by job value: Consumer and Business Services requires a building work contractor's licence from anyone who carries out or organises building work for others, and all building work must be supervised by a registered building work supervisor. Approvals run through PlanSA, where a development approval is made up of separate planning and building consents.

Trades that need a licence in South Australia
General contracting and renovation
The trigger in South Australia is the activity, not the value. Individuals and businesses must be licensed as building contractors — including subcontractors running a business — if they carry out or organise building work for others, or to sell or let land or buildings. All building work must be supervised by a registered building work supervisor.

Plumbing
Individuals, partners and companies must be licensed as plumbing, gas fitting or electrical contractors if they run a business that carries out or organises that work — and if you do the physical trade work yourself, you must also register as a plumber, gas fitter or electrician.

General contracting and renovation
The National Construction Code sets the technical provisions for designing and constructing buildings and plumbing and drainage systems, but it has no force of its own: the ABCB states that the NCC is given legal effect through state and territory building and plumbing legislation, and that adoption dates are set by each state's administration. Requirements can apply at different times, or not at all, because of state variations — and the ABCB notes that gasfitting and electrical work are not covered by the NCC at all.

Building and renovation permits in South Australia
In South Australia, "development approval" is an umbrella rather than a single document: PlanSA states that a development approval consists of one or more types of consent granted during assessment, and that one or more of planning consent, building consent and land division consent may be required. Planning consent is for development that may have a planning impact on its surroundings — building or extending a house, changing a land use, removing a significant tree — and is assessed against the planning rules. Building consent covers work such as building a carport or garage, a swimming pool, or demolition, and is assessed against the building rules; it is usually granted by a local council building officer or an independent accredited professional. Applications are assessed under the Planning, Development and Infrastructure Act 2016, and approval is needed before you start.
