Regulator: Office of the Technical Regulator (OTR) for technical standards; Consumer and Business Services (CBS) for licensing
SA uses an electronic Certificate of Compliance (eCoC) system — plumbers must lodge one within 7 days of completing regulated work. Plumbing licensing is split between the OTR for technical regulation and CBS for licence applications and renewals. The OTR maintains a searchable register of licensed plumbers. DIY plumbing is limited to replacing tap washers, cleaning showerheads, unblocking drains with a plunger, and replacing garden tap handles. Everything else requires a licensed plumber.
Typical build costs in Adelaide and regional SA as of early 2026: new residential construction runs $1,800–$2,800 per square metre for a standard project-home build, and $3,000–$5,000+ per square metre for custom architecturally designed homes. Renovation costs average $2,200–$3,500 per square metre depending on the scope. SA remains one of the more affordable states for construction, though labour costs have risen 15–20 percent since 2022 due to skilled-trade shortages. Concrete supply in Adelaide averages $250–$320 per cubic metre delivered. Structural pine framing (MGP10 90×45) runs about $4.50–$6.00 per lineal metre.
Adelaide has a Mediterranean climate — hot, dry summers frequently exceeding 40°C and mild, wet winters. This has significant implications for construction: concrete slabs poured in summer need aggressive curing (keep damp for 7+ days, or use curing compound) to prevent cracking from rapid moisture loss. Metal roofing expands substantially in extreme heat — allow for thermal movement in long runs. The Barossa Valley and Adelaide Hills have slightly cooler microclimates but increased bushfire risk. Most of SA falls within Termite Risk Area A (high risk) — termite management systems per AS3660 are essential for new builds and should be inspected annually in existing homes. Stormwater drainage must account for the city's clay soils, which have poor permeability and cause significant runoff during winter rain events.
Regulatory information is current as of April 2026 and is provided for general guidance. Always verify current requirements with PlanSA or your local council before starting work.
