Ask Chalkline about this →DBP stands for Design and Building Practitioners, the registration scheme established by the Design and Building Practitioners Act 2020 (NSW) for professionals working on Class 2 (apartments), Class 3 (boarding houses, care facilities), and Class 9c (residential care buildings) buildings.
Under the DBP Act, registered design practitioners must prepare and lodge regulated designs before construction starts, and registered building practitioners must provide a building compliance declaration confirming that the building is constructed in accordance with the regulated designs. This is separate from the contractor licence issued under the Home Building Act 1989 (NSW), which covers Class 1 and Class 10 residential building work. From 1 July 2026, renovation and alteration work on existing Class 3 and 9c buildings also falls under DBP obligations, and all registered building practitioners must hold Professional Indemnity insurance (verified 2026-05-08, NSW Government: Building classes and roles).
