How Building Certification Works in South Australia
A guide to SA building certification, accreditation levels under the PDI Act, the PlanSA portal, and bushfire building requirements.

SA certification framework
Building certification in South Australia is governed by the Planning, Development and Infrastructure Act 2016 (PDI Act). The Office of the Technical Regulator (OTR) accredits building surveying professionals who assess compliance with the NCC and state-specific requirements.
SA uses the term "accredited professional" for practitioners authorised to conduct building assessments. They assess plans for NCC compliance, conduct inspections, and issue certificates of occupancy for completed work.
Accreditation levels
South Australia accredits building surveyors at three levels. Level 1 can assess all building classes without restriction. Level 2 handles buildings up to three storeys and certain floor area thresholds, covering most residential and low-rise commercial work. Level 3 is restricted to residential buildings only (Class 1 and 10).
Each level requires specific qualifications and professional experience. For commercial or multi-storey projects, verify your practitioner holds the appropriate level before engagement.
PlanSA portal
PlanSA is the online planning and development assessment portal for South Australia. Building certification integrates with the PlanSA system, allowing accredited professionals to lodge assessments and issue decisions through the digital platform.
This has streamlined the certification process compared to the previous paper-based system. Applications, assessments, and decisions flow through a single platform, providing transparency for applicants and practitioners alike.
Bushfire building requirements
Properties in designated Bushfire Protection Areas (including parts of the Adelaide Hills, Mount Lofty Ranges, and other areas) must meet enhanced building standards under the NCC and the Minister's Specification SA 78A.
A Bushfire Attack Level (BAL) assessment determines the construction requirements for your site. Building certifiers verify compliance with the BAL requirements during plan assessment and construction inspections. Higher BAL ratings require more fire-resistant materials and construction methods, which increases building costs.
Heritage considerations
South Australia has significant heritage-listed buildings, particularly in Adelaide and regional towns. Building work on heritage-listed properties requires coordination between the building certifier and the South Australian Heritage Council.
The certifier assesses NCC compliance while the Heritage Council assesses heritage impact. Performance solutions may be needed where NCC compliance conflicts with heritage conservation objectives. Engaging a practitioner with heritage experience is advisable for these projects.
