Building practitioner registration and compliance in NSW
NSW requires building practitioners to hold a licence or registration before carrying out residential or commercial building work. The Home Building Act 1989 governs licensing for residential work, while the Design and Building Practitioners Act 2020 introduced a registration scheme for design and building practitioners working on class 2 and related buildings. NSW Fair Trading administers both schemes. This guide sets out 10 core obligations.
Coverage
Builders, trade contractors, and design practitioners carrying out residential building work (Home Building Act) and practitioners doing regulated design or building work on class 2 buildings and above (Design and Building Practitioners Act). This includes general builders, specialist contractors, engineers, architects, and building designers.
Legal basis
Home Building Act 1989 (NSW), Home Building Regulation 2014, Design and Building Practitioners Act 2020 (NSW), Design and Building Practitioners Regulation 2021. NSW Fair Trading administers licensing and registration.
The obligations
Obtain the correct licence or registration
Apply for and hold the correct contractor licence class under the Home Building Act, or registration under the Design and Building Practitioners Act, before performing any regulated work.
Lodge regulated designs with NSW Fair Trading
For class 2 buildings and related structures, lodge regulated design compliance declarations and supporting documents on the NSW Planning Portal before building work commences.
Issue a design compliance declaration
A registered design practitioner must issue a compliance declaration confirming the regulated design complies with the Building Code of Australia before the design is used for building work.
Maintain home building compensation fund cover
Hold cover through the NSW Home Building Compensation Fund (icare) for residential building work exceeding $20,000. Provide evidence of cover to the homeowner before entering the contract.
Enter compliant building contracts
Use contracts that comply with the Home Building Act requirements for residential work over $5,000, including cooling-off periods, progress payment schedules, and prescribed terms and warnings.
Keep building records and documentation
Maintain records of all building work, variations, inspections, certificates, and compliance documentation for at least 10 years. Records must support any future audit or dispute resolution.
Complete CPD and maintain competency
Complete the continuing professional development requirements for licence renewal. CPD topics must include legislative updates, safety, and technical competency relevant to the licence class.
Renew the licence or registration before expiry
Submit renewal applications before the licence or registration expires. Home Building Act licences run for 1 to 3 years; DBP Act registrations are renewed periodically. Working on an expired credential is an offence.
Comply with the duty of care to homeowners
Building practitioners owe a statutory duty of care to current and future homeowners to avoid economic loss caused by defective building work. This duty is retrospective and non-excludable.
Report notifiable incidents and defects
Report serious defects in class 2 buildings to the Building Commissioner. Cooperate with Fair Trading investigations and respond to building rectification orders within the prescribed timeframe.
What happens if you do not comply
Unlicensed residential building work carries penalties of up to $110,000 for individuals and $330,000 for corporations. Failure to lodge regulated designs under the DBP Act attracts penalties of up to $110,000. The Building Commissioner can issue stop-work orders, prohibition orders, and building rectification orders.
Reporting requirements
Regulated designs and compliance declarations must be lodged on the NSW Planning Portal. Home building compensation fund cover must be evidenced before contract execution. Serious defects in class 2 buildings must be reported to the Building Commissioner.
